identified itself as PLEXTOR DVDR PX-755A. DMA (Direct Memory Access) and autorun was enabled for all devices.

And another screenshot
from Nero InfoTool below:

From the screenshot from
Nero InfoTool above, we can see the Plextor PX-755A does not support Mount
Rainier. The drive came shipped with firmware version 1a02.

Firmware
Update:

We checked Plextor's
website and found a later firmware version. (1.02) so we proceeded to update the
firmware.

Below we can see the
firmware update process in action.

Our review PC was
restarted after the firmware update process had completed.

We once again run
InfoTool to check that the firmware had updated correctly (see the above
screenshot).

Installed
Software:

Windows XP Professional
x64 Edition is installed on the computer along with Service Pack 1. We will be
using the following software in this review:

• Nero Burning ROM version 6.6.1.4
  
• Nero CD/DVD Speed V4.11
  
• Nero InfoTool v4.00
  
• Slysoft CloneCD v5.2.5.1
  
• Exact Audio Copy v0.95 beta 2
  
• K-Probe v2.5.1
  

Features and techniques:

AUTOSTRATEGY: The best
DVD Quality

For the best writing
quality, the drive's AUTOSTRATEGY technology selects the optimized write
strategy for every DVD disc and, if necessary, creates a new write strategy for
unknown media. (DVD+/-R)

A separate database
stores all strategies that are created by the AUTOSTRATEGY function for media
that is not currently supported in the firmware. A maximum of 31 write
strategies can be held in the non-volatile memory of the drive. The entries can
be activated or de-activated, and deleted. The list of database entries can be
viewed and saved or printed.

The user can select the
write strategy from the AUTOSTRATEGY database or from the database that resides
in the drive's firmware by activating a different Mode.

Remark: This function
is only available for DVD+R and DVD-R media (4X and higher).

1. Auto Selection
Mode:

The drive will select the
best write strategy, whether it is located in the AUTOSTRATEGY database or in
the firmware database. If no suitable strategy is found, AUTOSTRATEGY will
create a new, optimized strategy in the database.

2. AUTOSTRATEGY On
Mode (Forced):

The drive will create a
new write strategy for every new recording, whether a corresponding strategy
exists already in the firmware or not.

3. AUTOSTRATEGY On
Mode:

The drive will use the
write strategies from the AUTOSTRATEGY database for recording. If no suitable
strategy is found, a corresponding write strategy from the firmware's database
will be used.

4. AUTOSTRATEGY Off
Mode:

The drive will only use
the write strategies from the firmware's database for recording. If no
corresponding write strategy is found, the default write strategy will be
used.

Media Quality
Check

To assure you're
receiving the best results with your drive, this function checks the quality of
blank media.

Write strategy
creation

This function offers to
create a new write strategy for your blank media. The drive will create a new
write strategy in the AUTOSTRATEGY database without recording a disc. It is
possible to create several write strategies for the same media, which can be
useful if there is a quality difference among media with the same MID code.

PlexTools Professional XL Auto Strategy Database

PlexEraser

PlexEraser is a data
destruction utility that makes a recorded CD-R or DVD disc unreadable. The drive
will "re-record" over the Lead-in and data sectors of a write once disc
rendering the disc data unusable. Initially this feature will support DVD+/-R
and CD-R media. Firmware upgrades will add support for DVD+/-R DL media.

SecureRecording

The SecureRecording
function lets you write on a CD-R disc and protect the data with a password. To
view the contents of a password-protected disc-or even to see a catalog of
files-the user must enter the correct password. The password can be entered via
PlexTools Professional software, or with SecuViewer software.

Buffer underrun
proof

The buffer underrun proof
technologies offer a solution to prevent writing failures during the burning
process for CD and DVD by pausing the burn if the data to the drive write buffer
is slowed or stopped. The drive resumes the burn process after the drive write
buffer is refilled.

Silent
mode

If the drive needs to be
used in a quiet environment, the drive can be switched to silent mode. Unique
technology that sets the drive for super-silent operation. By controlling access
speed, read/write speed, and tray opening and closing speed, you reduce drive
noise to a whisper. This technology is excellent for recording studios or
offices where low noise is required.

SpeedRead

Enable reading CD-R media
up to the maximum speed of the drive. Discs that may be damaged due to
mishandling or improper use may shatter due to the higher rotational forces
reached at the maximum read speed of the drive. The drive's maximum read speed
is therefore limited as a safety function. SpeedRead enables the user to
increase the read speed of the drive to the maximum possible. Plextor recommends
examining each disc before enabling this function.

GigaRec

GigaRec lets you change
the recording capacity of a standard CD-R disc from 70 percent up to 130 percent
of its standard capacity. You can use GigaRec for CD-DA or data writing at 4X
and 8X disc-at-once (DAO). The feature allows you to get that extra storage on a
single disc for a larger project. For smaller projects, like an audio master,
the feature enables you to use the entire capacity of the disc, increasing the
size of the pits and lands for higher reproductive quality.

VariRec

VariRec provides user
adjustment of the recording power above or below a default level. The default
level reflects an optimized laser power setting with reduced jitter. Changing
this setting will result in a change of sound or sound quality and may increase
the playability or compatibility with existing players.

Q-Check

PlexTools Professional
software provides a suite of diagnostic tests for blank and recorded media. The
pre-recording tests of blank media allow you to choose the best media brands and
recording parameters for your drive. The post-recording tests quantify the
recording session and provide analyzer-type results to guarantee you're getting
the best recording possible.

 

PoweRec

Plextor Optimized Writing
Error Reduction Control (PoweRec) adjusts laser power and writing speed so
they're at the optimum settings for that particular disc. Using real-time
monitoring of the write data, PoweRec can increase or decrease write power and
speed to guarantee the best possible writing quality with whatever brand media
is used.

PlexTools
Professional

This software tool offers
a complete suite of recording applications and supports your drive's advanced
quality check functions. Advanced drive settings such as GigaRec or Silent Mode
can be changed. High quality audio extraction, various recording modes, and
copying of files or disc images can be selected. Media testing with the drive's
Q-Check function allows you to select the best media for your drive and examine
the quality of your recordings. (www.plextools.com)

PlexTools Professional
XL

Based on the existing
solid code of PlexTools Professional, PlexTools Professional XL offers more
features and extra options. The new layout with resizable windows and improved
graphs, enhanced audio functions and project options, as well as the unique
update check system, is designed and tuned for the demanding user. (www.plextools.com)

Writing Technology:

In the following tests,
we take a look at the disc writing technology used by the Plextor
PX-755A.

For these tests we simply
burned a disc with Nero CD-Speed's 'create data disc" function.

CD-Recordable:

The Plextor PX-755A uses
CAV (Constant Angular Velocity), to write at its maximum
speed of 48x. This gives an average write speed of 36.68x, and as we can see, it
took the PX-755A 2 minutes 44 seconds to write the disc.

Below we have 3 other
drives for comparison.

The Samsung SE-W164C uses
CAV (Constant Angular Velocity), to write at its maximum
speed of 48x. This gives an average write speed of 37.22x.

The
Samsung TS-E552U uses P-CAV (Partial-Constant
Angular Velocity) to write at its rated
speed of 40x. This gives an average speed of 34.39x.

The LG GSA-5160D uses
Z-CLV, (Zone-Constant Linear Velocity), to write at
its maximum speed of 40X. The drive wrote the last zone at 40.41X and this gives
an average speed of 31.70x.

 For comparison we have made the
following table: 

As we can see from the
table, the Plextor PX-755A was one of the fastest drives when it comes to
writing CD-R's.

CD-Rewritable:

The Plextor PX-755A uses
Z-CLV (Zoned Constant Linear Velocity) to write
CD-RW at its maximum speed of 24x, with an average write speed of 23.51x and a
total write time of 3 minutes and 50 seconds.

Below are some other
drives for comparison.

The Plextor PX-750A uses
CAV (Constant Angular Velocity) to write CD-RW at its
maximum speed of 24x, with an average write speed of 17.81x and a total write
time of 5 minutes and 13 seconds.

The Samsung SE-W164C uses
Z-CLV (Zone Constant Linear Velocity) to write CD-RW
media at its maximum speed of 32x, with an average write speed of 28.32x and a
total writing time of 3 minutes 35 seconds.

The NEC ND-3540A uses Z-CLV,
(Zone-Constant Linear Velocity) writing
technology to write at 32X for CD-RW discs, the average speed is 29.75x.

For a better overview we
present the following comparison table:

As we can see from the
table, the Plextor PX-755A was about average when writing CD-RW
media.

16X DVD+R
Writing speed:

The Plextor PX-755A uses
CAV (Constant Angular Velocity) to write DVD+R at the
maximum supported speed of 16x. This gives an average write speed of 11.28x and
a writing time of 6 minutes and 2 seconds.

16X DVD-R
Writing speed:

The Plextor PX-755A uses
CAV (Constant Angular Velocity) to write DVD-R at the
maximum supported speed of 16x. This gives an average write speed of 11.17x and
a writing time of 5 minutes and 27 seconds.

Below are some write
graphs from some other drives for comparison.

The Pioneer DVR-110 uses
CAV (Constant Angular Velocity) to write DVD-R at the
maximum supported speed of 16x. This gives an average write speed of 11.59x and
a writing time of 6 minutes and 1 second.

The NEC 3540A uses CAV
(Constant Angular Velocity) to write DVD+R at 16x. This gives an average writing speed of 11.81x and a writing time of 5 minutes and 58
seconds.

The Philips DVDR16LS uses
CAV, (Constant Angular Velocity) to write DVD+R at 16x. The
average speed is 11.33x and total writing time is 6 minutes and 8 seconds. The
average speed is lower and the writing time is higher than it could have been
due to the Walking OPC generation 2 using some time to constantly adjust the
writing quality, we could see this as constant dips in the speed
curve.

The LG GSA-4163B uses
P-CAV, (Partial-Constant Angular Velocity) to write
DVD-R at 16x. The average speed is 12.90x and total writing time is 5 minutes
and 20 seconds.

Below, we made a
comparison table:

*1 '“ Actual writing speed
was max 14x due to USB-Bridge limitations.
*2 '“ Actual writing speed was max
13x due to USB-Bridge limitations.

From the table above, we
can see that the Plextor PX-755A is about average when it comes to burning DVD±R
media.

8X DVD+RW
writing speed:

The Plextor PX-755A uses
P-CAV, (Partial Constant Angular Velocity) to write DVD+RW
at 8x. The average speed is 7.88x and total writing time is 7 minutes and 18
seconds.

The Plextor PX-755A was
above average when writing DVD-RW media

10X DVD+R DL
writing speed:

The Plextor PX-755A is
the world's first drive to support 10x writing speed on DVD+R DL
media.

The Plextor PX-755A used
P-CAV, (Partial Constant Angular Velocity) to write
the Verbatim DVD+R DL disc at 10x. The average speed was 8.61x and the total
writing time was 14 minutes and 14 seconds.

Below are three other
drives for comparison.

The Pioneer DVR-110 uses
Z-CLV, (Zone-Constant Linear Velocity) to write
DVD+R DL at 8x. The average speed is 7.00x and total writing time is 18:06
minutes.

The NEC ND-4550A uses
Z-CLV (Zone Constant Linear Velocity) to write DVD+R
DL media at 8x which gives an average write speed of 6.55x and a total write
time of 18 minutes and 40 seconds.

The BenQ DW1640 uses
P-CAV (Partial Constant Angular Velocity) to write
DVD+R DL at its maximum speed of 8x. This gives an average write speed of 7.32x
and a total write time of 15 minutes and 36 seconds.

time of 17 minutes and 55 seconds.

The NEC ND-4550A uses
Z-CLV (Zone Constant Linear Velocity) to write DVD-R
DL media at 6x which gives an average write speed of 5.67x and a total write
time of 20 minutes and 41 seconds.

We present the table
below for easy comparison.

With its 10x DVD+R DL
write speed, the Plextor PX-755A was the fastest drive writing our test DVD+R DL
media, and was around average when writing our DVD-R DL media.

Book type
(Bitsetting):

The Plextor PX-755A
supports auto Bitsetting, and supports DVD+R/DL media with DVD-ROM book
type.

Here is how you could
check if your discs are really written with DVD-ROM book type:

Start Nero CD-DVD Speed
and click the Disc info button and you should get the following
screen:

DVD+R DL with
book type DVD-ROM.

Another quick test is to
start Nero CD-Speed and look at the disc information:

This
should say DVD-ROM.

Now let us take a look
at the reading performance of the Plextor PX-755A on the next page….

---

Reading
performance:

For these tests we will
use Nero CD/DVD-Speed to read various CD and DVD's, including audio discs and
DVD-media. As already mentioned in the introduction, this drive
supports:

• DVD-ROM :
  16x
  
• CD-ROM :
  48x 

Pressed
discs:

For this test we used a
pressed CD-ROM disc containing the Roxio Media Creator 7.5 install CD that is
close to 75 minutes in length. Below you will see the produced
result:

The Plextor PX-755A
reached 48.51x, and will reach faster speeds on a full disc. Let's compare the
result in the table below:

The Plextor PX-755A was
above average reading a pressed CD-ROM.

CD-Recordable
Discs:

For this test we made a
copy of the original Roxio Media Creator 7.5 install CD. The disc we used was a
Ricoh 52X certified CD-R disc manufactured by Moser Baer India. 

As we can see from the
above screenshot, the Plextor PX-755A reached 47.33x when reading CD-R. This
gives an average read speed of 35.85x.

Now let us compare with
the drives below.

Once again the Plextor
PX-755A was above average for reading CD-R media, but the seek times were quite
slow.

* Some drives
including the NU HDW-164 will simply execute the seek command without actually
moving the pickup.

 CD-Rewritable discs:

Again, we made a copy of
the original Roxio Media Creator 7.5 install CD; this time we used a Verbatim
Ultra Speed (32X) CD-RW disc made by Mitsubishi Chemicals
Corporation.

As we can see above, the
Plextor PX-755A is speed locked to 40x when reading CD-RW; now let us compare it
to other drives below.

The Plextor PX-755A was
one of the fastest drives at reading CD-RW media.

* Some
drives including the NU HDW-164 will simply execute the seek command without
actually moving the pickup.

100
minutes CD:

We used Nero CD-DVD Speed
to measure the transfer rate. The 100 min disc we used is slightly larger than
the disc used for the other tests, to be exact it is 97 minutes and 50 seconds
long.

As we can see, the
Plextor PX-755A had no problems in reading the disc.

Audio '“
Digital Audio Extraction:

To test the digital audio
extraction performance of the Plextor PX-755A, again we used Nero CD/DVD-Speed
to measure the transfer rate. The audio disc we used is slightly larger than the
disc used for the other tests, to be exact it's nearly 79 minutes in length
(78:53:31).

The Plextor PX-755A
reached 42.58x when reading our Audio-CD; let us compare the result with other
drives:

The Plextor PX-755A
performed about average reading the Audio-CD.

* Some
drives including the NU HDW-164 will simply execute the seek command without
actually moving the pickup.

For this test we used EAC
(Exact Audio Copy) to test the drives Audio extraction performance. As we can
see from the screenshot below, the drive supports accurate stream and C2 Error
Info.

Below is the results
produced by EAC:

 Burst
mode

 Secure
mode

The drive performed very
well in burst mode, but was slower in secure mode.

Advanced
audio '“ DAE quality test:

Before we move on to
testing DVD read speeds, we will take a last audio test, and this time we used
the 'Advanced DAE Quality Test" feature in CD-Speed. For this test we used a
CD-R media from RICOH (Thanks to RICOH Europe (BV) for sending us this
media).

The extracting quality is
excellent, and the drive performed flawlessly with this test, an excellent
result.

DVD
reading performance:

Again, we
will use Nero CD-Speed to measure the reading performance, this time for various
types of DVD discs. The drive should read pressed single layer DVD-discs at
16X.

DVD '“
DVD-Video:

For our DVD reading
performance tests we are going to start with a single and Double Layered DVD
video discs. While only 1X speed is required to watch DVD movies, it's useful to
be able to read the discs at higher speeds if you're going to extract (rip) the
content of the disc to your hard drive.

DVD-Video Single Layer

 
DVD-Video Double Layer (OPT)

DVD-Video Double Layer (PTP)

The Plextor PX-755A is
not RIPLOCKED and reads a pressed DVD-Video at up to 16x for a Single Layer
disc, and at 12x for a Double Layer disc.

Now let us test a pressed
DVD-ROM disc. For this test we used the 'Plextor PX-716A" install DVD, which is
around 4.37 Gigabyte in size.

As we can see from the
above screenshot, the Plextor PX-755A reads a DVD-ROM at 16x.

The Plextor PX-755A
performed well with our SL DVD-Video test. It was one of the fastest drives at
reading a pressed SL DVD-Video disc. With the Double Layer DVD-Video it was
among the fastest drives.

DVD

For this test we used a
Verbatim 16X DVD+R and a Verbatim 8X DVD+RW with about 4.4GB of data. Below are
the results:

The read speed is locked
at 12x when reading DVD+R/RW media. The Plextor PX-755A performed around average
when reading DVD+R media, but above average when reading DVD+RW
media.

reading DVD-RW media.

Overall
thoughts:

Overall reading
performance is very good, we would have liked faster DVD+R and DVD-R read
speeds. During our tests, the Plextor PX-755A proved to be a reliable
reader.

But now it's time to
head on to a more interesting part: Writing CD-R and CD-RW
discs…

---

The specifications of the
Plextor PX-755A state that the drive is able to write CD-R discs at 48x and
CD-RW at 24x. Let us find out how the drive really performs in speed and
quality.

Writing Data CD-R
discs:

For our data writing
tests, we simply set up a new compilation of 703Mb using Nero Burning ROM
software. Writing method used is DAO (Disc At Once), and
the disc is set up as a non-multisession disc with 'finalize disc" enabled. The
screenshot below shows how long it takes to write a disc at the highest speed.
(48x):

The drive took 2 minutes
and 43 seconds to write the disc at 48x. Let us see how this compares to other
drives in the table below:

Write
Quality:

We will test CD-R discs
from many different CD-R manufacturers. To really measure the write speed, we
used the 'create data CD" function in Nero CD-Speed. The discs were written at
the maximum speed that the drive supports. For the quality test, we used K-Probe
2 which is a tool developed by a Lite-On employee. It runs under Windows and
works with drives made by Lite-On. Also note that different drives and different
reading speeds may affect the results obtained when scanning the discs. We used
a Lite-On SOHR-5238S drive with firmware 4S09 and scanned the discs at 48X
speed.

A written CD-R disc will
always have some C1 errors; C1 errors are easily corrected by the drive's error
correction capabilities. The next level of errors is C2, while C2 errors could
also be corrected by most drive's error correction capabilities; they are not
wanted on a good quality disc. A good disc should not contain any C2 errors, and
preferably have an average C1 error amount of below 2.0 for the best discs, or
at least below 10.0 averages for good quality discs. After C2 errors, there are
only un-correctable errors that will make a disc unusable.

Below are the obtained

Due to
requests from our readers, we will add a few write quality tests with
re-writable media. Settings and testing procedures are the same as used earlier
in this review, so you may want to go back and read them if you are unsure. All
discs used for these tests have been written to before, but none have been

Summary:

The CD-R/RW
writing quality on the Plextor PX-755A is very good.

So let us head on to
next page and read about DVD-Writing
performance…

---

The specifications of
this drive tell us that it should write DVD±R at 16x and DVD+RW/-RW at 8x/6x. In
this part, we will measure the write time for various types of DVD+R/RW and
DVD-R/RW discs. We will also focus on write quality and media compatibility.

DVD-Writing
performance:

In this test we will
measure the time for writing to DVD±R discs. We used Nero Burning Rom to burn an
ISO compilation containing 4480MB of data. We used the Disc-At-Once write
method.

For these DVD writing
tests, the Plextor PX-755A was set to the following.

Look below for the
results.

The results are about
average when compared to other drives.

Write
quality:

You should
first notice that this is not a scientific and professional way to test the
discs. But according to our testing done in recent months, we would conclude
that there is a clear link between the quality reported when scanning the disc
and the playability of the disc in different devices. Also notice that different
drives report different amounts of errors. K-Probe was designed to work with
Lite-On
DVD-Writers, so we recommend
using a DVD-Writer from Lite-On. In this test we
use a Lite-On SHW-16H5S
DVD-Writer, as already said; remember that scans done with a Lite-On DVD-ROM or
Lite-On combo drive
can't be compared with the results obtained with a Lite-On DVD-Writer.
Also remember that
different PI/PO ECC sum settings along
with different reading speeds in K-Probe will affect the result, we use these
settings;  PI (Parity Inner) set to summarize 8
ECC blocks,
PIF (Parity
Inner Failures) set to
summarize 1 ECC block, reading
speed: 4X CLV (Constant
Linear Velocity). Setting the PI sum to 8 and the PIF sum to 1 will give
a result that we may compare to the standards for DVD+R/RW and
DVD-R/RW.

But what is
a good scan? That is a discussion that we don't think will end soon, as
different drives report different amount of errors, some players are more
picky about media than others, and so on. But as a comparison we present you
with a scan from two pressed DVD discs:

This scan shows the results from a pressed DVD-Video disc
(GoldenEye).

 

This scan
shows the result from a pressed DVD-Video disk (The Green Mile). Notice the
error jump when shifting to the second layer (the error level actually drops
from the end of the first layer to the beginning of the second
layer).

If you read
below, you will see that both the pressed DVD-discs are well within the
standards.

Download
the ECMA 267 Standard for
DVD-ROM, the ECMA 337 Standard for
DVD+R/RW and the
ECMA 338 Standard for
DVD-R/RW at http://www.ecma-international.org if you want to look
at the standards for yourself. Here is some data from the ECMA standards (same for
DVD-ROM, DVD-R/RW and DVD+R/RW):

Random
errors:

A row of an ECC Block that has at least 1 byte in error constitutes a PI
error. In any 8
consecutive ECC Blocks the total
number of PI errors before correction shall not exceed 280.

Here we see
that a PI error is defined as a row in an ECC block having 1 byte
or more containing errors and that the sum of PI errors in 8 ECC blocks after each
other should not exceed 280 PI errors.

But what is
a row and what is an ECC block? Again we
refer to the ECMA standards. We do
not copy and paste everything, but if you're interested, look in the
ECMA standards. A row is
182 bytes long where the last 10 bytes contain PI (Parity Inner)
information. An ECC block is 208 rows
long where the last 16 rows contain the PO (Parity Outer)
information. This gives us a maximum possible PI error amount of 208 errors per
block and for 8 blocks after each other this sum is of course 8 times higher,
giving a maximum possible amount of 1664 PI-8 errors. In practical use, a disc
with 1664 PI-8 errors is unreadable.

According
to our tests the specified max PI-8 sum of 280 for good discs seems to be a good
guideline, as some readers have problems reading discs when the PI-8 errors is
over 300 and most players starts to have problems when the PI-8 error level
reaches 600 or more.

But what
are the PIF errors that K-Probe
reports? They are Parity Inner Failures, meaning errors left after PI
correction. Only the ECMA 337 standard
describes the Parity Inner Failures. So how is a Parity Inner Failure defined?
Here is what the ECMA 337
states:

'If a row of an ECC Block as defined in 13.3 contains more than 5 erroneous
bytes, the row is said to be 'PI-uncorrectable"."

In theory, an ECC block may in the worst case have 208 PIF since every ECC block is 208
rows long. But the ECMA 337 standard goes further and
specifies the max amount of accepted PI Failures (uncorrectable errors) allowed on a good disc:

'In any
ECC Block the number of
PI - uncorrectable rows should not
exceed 4."  

This means
that when the PIF sum is set to 1,
the maximum error value should not exceed 4. The theoretical maximum value for
PIF is 208
errors.

But what
makes a disc unreadable? A POF (Parity
Outer Failure) error will make the disc unreadable, but K-Probe
does not display the POF's.

Notice
that there are other aspects such as disc reflectivity, jitter, tracking errors
and so on that also will affect the readability of a DVD disc '“ but for this we
do not have measuring equipment available.

Also,
another note is that we have scanned the discs at 4X CLV speed, by lowering
the speed to 2X(DVD-R/RW)/2.4X(DVD+R/RW) or 1X the amount
of reported errors may drop on some discs. We scanned at 4X CLV due to lower speeds
taking too much time.

To see if
there is a connection between the reported amount of errors and readability of
the discs we also include the reading curve from a NEC ND-3540A DVD-Writer. The
reason why we have changed the reader is that some companies disliked that we
used a modified firmware to obtain 16x reading speed. So to please them, we are
now using a drive that reads DVD+R/-R media at 16x as default. A small speed reduction near the end is still
accepted on good discs, but serious reading problems or reading failures is a
bad sign.

Easier explanation on how to read the test
results.

Maybe this
got too technical, and you are wondering what to look for in KProbe reports?

Use this as
a guideline for good discs:

• PI (Parity
  Inner): No larger areas
  on the disc should exceed 280 PI-8 errors, do not worry too much about high
  single spikes that exceed 280.
  
• PIF (Parity Inner
  Failures): No larger areas
  on the disc should exceed 4 PIF-1 errors, do not worry too much about high
  single spikes that exceed 4.

And as
always; lower is better

And look at
the reading curve; if it looks clean with no dips it should be good, a small
slowdown near the end is accepted.

DVD+R media compatibility and write quality:

In these tests we will be
using a Lite-On SHW-16H5S with firmware LS0T along with K-Probe to measure the
disc quality. We will also be using the NEC ND-3540A with firmware 1.03 along
with CD-Speed for our read-back tests. 

For these DVD writing
tests, the Plextor PX-755A was set to the following.

The Plextor PX-755A has
handled the Verbatim DVD-RW media well. A very good result.

To sum it
up: Overall, the
write quality is generally good/very good on DVD-R and DVD-RW media.

Head on to next page
and read about DVD+R DL compatibility and write
quality...

DVD+R/-R Double Layer writing
speed and compatibility:

The Plextor PX-755A
supports the DVD+R DL/-R DL standard for writing Double Layer/Dual Layer discs
with a size around 8.5 GB at a writing speed of 10x for DVD+R DL, and 6x for
DVD-R DL. Let us first take a look at the media we will use:

Let's find
the manufacturer and media information too, for this we will use Nero CD-DVD
Speed version 4.11:

Verbatim 8x '“
Manufactured by Mitsubishi Kagaku Media. Thanks to Verbatim for sending us this
media.

This media is
manufactured by Mitsubishi Kagaku Media. Thanks to SVP UK for sending us this
media.

Ricoh JPN D00,
manufactured by Ricoh. Thanks to Ricoh Europe for sending us this
media.

Infiniti reference series
- Manufactured by CMC Magnetics. Thanks to Medea International UK for sending us
this media.

Testing
procedure:
We
created an ISO Image from a pre-authored DVD-Video compliant file set, with a
total on-disc size of 8146 MB. We then wrote this image file using Nero Burning
ROM 6. Below are the results:

Verbatim 8x media

Nero reported a
successful burn with the Verbatim 8x media in 15 minutes and 7 seconds. (write
speed 10x)

Let us take a look at the
K-Probe result:

Brand:	Verbatim '“ Thanks to Verbatim for sending us this media.
Manufacturer:	Mitsubishi Kagaku Media
Code:	MKM 003
Disc Type:	DVD+R DL
Capacity:	8145MB
Certified Speed:	8x
Write Speed:	10x (P-CAV)
Write Time:	15m:07s
PI-8 errors Average/Sec:	3.01
PI-1 failures (PIF) Avg/Sec:	0.10

Although there are a few
PIF spikes and the usual cluster of PIF errors at and around the layer break,
the result is very good.

Verbatim 2.4x Media

Nero reported a
successful burn with the Verbatim 2.4x media in 19 minutes and 8 seconds. (write
speed 6x)

Let us take a look at the
K-Probe result:

Brand:	Verbatim '“ Thanks to SVP UK for sending us this media.
Manufacturer:	Mitsubishi Kagaku Media
Code:	MKM 001
Disc Type:	DVD+R DL
Capacity:	8145MB
Certified Speed:	2.4x
Write Speed:	6x (CLV)
Write Time:	19m:08s
PI-8 errors Average/Sec:	5.16
PI-1 failures (PIF) Avg/Sec:	0.12

The result is once again
very good, considering this 2.4x media was written at 3 times its rated
speed.

Ricoh Media

Nero reported a
successful burn with the Ricoh 8x media in 16 minutes and 55 seconds. (write
speed 8x)

Let us take a look at the
K-Probe result:

Brand:	RICOH '“ Thanks to Ricoh Europe for sending us this media.
Manufacturer:	RICOH
Code:	JPN D01
Disc Type:	DVD+R DL
Capacity:	8145MB
Certified Speed:	8x
Write Speed:	8x (P-CAV)
Write Time:	16m:55s
PI-8 errors Average/Sec:	17.28
PI-1 failures (PIF) Avg/Sec:	2.51

PI and PIF errors are out
of specification, with alarming spikes around and after the layer break. A poor
result.

Infiniti 2.4x Media

Nero reported a
successful burn with the Infiniti 2.4x media in 27 minutes and 41 seconds.
(write speed 4x)

Now let us take a look at
the K-Probe result:

Brand:	Infiniti '“ Thanks to Medea International UK for sending us this media.
Manufacturer:	CMC Magnetics
Code:	CMC MAD D01
Disc Type:	DVD+R DL
Capacity:	8145MB
Certified Speed:	2.4x
Write Speed:	4x (CLV)
Write Time:	27m:41s
PI-8 errors Average/Sec:	3.50
PI-1 failures (PIF) Avg/Sec:	0.50

Once again we have
alarming spikes at the layer break, a poor result.

Now let us try and read
the Double Layer media back, first on the Plextor PX-755A and then the BenQ
DW1640.

As we can see from our
results, both drives were able to read our Verbatim media without to many
problems. However, both drives had problems reading our Ricoh and Infiniti
media.

Let's compare the Plextor
PX-755A with some other DL capable drives.

*1 Verbatim DVD+R DL
(MKM001)
*2 Traxdata DVD+R DL (RITEK D01)
*3 Ricoh DVD+R DL (RICOH JPN
D00)
*4 Datawrite DVD+R DL (CMC MAG D01)
*5 Verbatim DVD+R DL (MKM

*6 Ricoh DVD+R DL (JPN D01)

DVD-R
DL

As mentioned at the top
of this page, the Plextor PX-755A supports the DVD-R DL standard at 6x. Let us
first take a look at the media we will use:

Let's find
the manufacturer and media information too, for this we will use CD-Speed
4.11:

This media is
manufactured by Mitsubishi Kagaku Media. Thanks to SVP UK for sending us this
media.

Again, we used Nero
Burning Rom 6 to write the DVD Image:

The Plextor PX-755A took
18 minutes and 39 seconds to write the Verbatim DVD-R DL media at 6x.

To check the disc quality
we used the Plextor PX-755A along with PlexTools Professional XL to test our
disc. First we carried out a sum8 test, and followed this by a
sum1 test.

PlexTools
Professional XL sum8 test

PlexTools Professional XL sum1 test

Brand:	Verbatim '“ Thanks to SVP UK for providing this media.
Manufacturer:	Mitsubishi Kagaku Media
Code:	MKM 01RD30
Disc Type:	DVD-R DL
Capacity:	8145MB
Certified Speed:	4x
Write Speed:	6x (CLV)
Write Time:	18m:39s
Sum8 error total PIE	191050
Sum1 error total PIF	3135

As we can see from our
PlexTools Professional XL results, the Verbatim DVD-R DL media has written with
very good quality

We will now check the
read-back curves on two different drives.

Plextor PX-755A read-back test

BenQ DW1640 read-back test

As we can see from the
above read-back tests; both drives were able to read the Verbatim DVD-R DL media
without problems.

Standalone DVD-Player compatibility:

We only have 3 standalone
DVD-Players available and 1 standalone DVD-RAM DVD-R recorder to test the DVD+R
DL medias (Book Type: DVD-ROM) and the DVD-R DL media (Book Type:
DVD-R):

• Panasonic
  DVD-RV32
  
• Panasonic
  SA-HT520
  
• Proline DVDP350

• Panasonic DMR-E50
  recorder

Compatibility
results: 

All our DVD Standalone
devices played the Plextor PX-755A burned Verbatim DVD+R DL media, but two of
our standalone players had problems playing the PX-755A burned Ricoh and
Infiniti DVD+R DL media, with both players failing at the layer break.

Only one DVD Standalone
device would play the Plextor PX-755A burned DVD-R DL media without any
problems.

We would like to mention,
that the compatibility issue with standalone DVD Players/Recorders and the DVD-R
DL media format is caused by incompatibilities with the standalone devices used
in this review, and not the Plextor PX-755A or media format used.

Summary: All our Verbatim double layer
media burned with very good quality, but there was clearly issues with the Ricoh
and Infiniti media. Let us hope this can be fixed with a future firmware update
for the Plextor PX-755A.

Let us take a look at
some of the features of PlexTools Professional XL on the next
page….

Plextor was kind enough
to supply us with a license for PlexTools Professional XL. On this page we will
take a look of some of the features of this application.

We will first take a look
at the features offered by PlexTools Professional XL, and we will then test some
of the advanced media diagnostic features of the Plextor PX-755A and PlexTools
Professional XL.

This application is used
for making your own disc compilations, and supports many formats including
DVD-Video and Audio CD.

Media player

You can play your media
files using this application. The application supports many audio and video
formats. The files can be played directly from a disc inserted in the drive, or
from the hard drive.

CD diagnostic
tests:

PlexTools Professional XL
is one of the most advanced diagnostic applications currently available for the
home user. In these tests, we will briefly run through the tests available for
testing CD-R/RW media.

Blank
media tests:

Write simulation test

Allows a simulated write
test, this can be useful for checking your system setup.

FE/TE test

Checks the quality of the
blank media and the drive lasers ability to focus and track the blank disc. It
will also recommend a maximum burning speed.

Recorded
media tests:

Read
transfer rate test

Checks the drives ability
to read the recorded media, any slowdowns could indicate a problem with the
recorded disc.

C1/C2 disc quality scan

Checks the quality of the
recorded media, in the screenshot above, the media has been recorded with good
quality.

CD All in
one test:

One of the nice features
of PlexTools Professional XL is the applications ability to do unattended
testing. This groups several tests and runs them in sequence.

We choose to include 3
tests.

⋅        
Read transfer
rate test
⋅        
Q check C1/C2
test
⋅        
Q check
Beta/Jitter test

Below is our
result.

The amount of information
presented with this test is staggering, and should prove invaluable to the
enthusiast.

DVD
diagnostics tests:

We will now carry out
some diagnostic tests with DVD recordable media, using the Plextor PX-755A and
PlexTools Professional XL. All our tests will be carried out with the 'Good
Accuracy" setting in PlexTools Professional XL.

Blank
media tests:

We carried out some blank
media tests with PlexTools Professional XL, and below you can find our obtained
results.

DVD write simulation test

In this test we used a
TDK 16x DVD+R media to test the maximum writing speed we could expect from this
media.

FE/TE test

The FE/TE test checks the
drive lasers ability to focus and track the blank media, and will also suggest a
maximum burn speed.

Recorded
media tests:

We will now run selected
tests using PlexTools Professional XL, which checks the recording quality of our
previously recorded DVD media.

DVD read test

This simply checks the
media for errors.

Sum8 (PIE) test

This test scans our
recorded media for PIE errors and reports them in a familiar graph.

Sum1 (PIF) test

This test scans our
recorded media and reports PIF errors and presents them with a familiar
graph.

Read transfer rate test

This test shows the
drives ability to read our recorded media; any major slowdowns could indicate a
problem with the recording quality of our recorded media.

TA test inner

TA test middle

TA test outer

The TA test checks the
quality of the recorded media by sampling the inner, middle, and outer sections
of the disc. It does this by measuring the 'lands and pits" of the recorded
disc.

Generally speaking, the
narrower the peaks the better, and each peak should be clearly defined from the
adjacent peak and should not merge to much with the adjacent peak.

All In
One test:

For this test we used a
previously burned DVD+R media manufactured by TDK. We choose to include 3
tests.

⋅        
Sum8
test
⋅        
Sum1
test
⋅        
Beta/Jitter
test

Below is our
result:

Once again the amount of
information given with this test is quite staggering, and gives a very good
representation of the quality of a previously recorded media. This data is
invaluable to the enthusiast.

To sum
up:

PlexTools Professional XL
is a very sophisticated application, and it is clearly aimed at the
enthusiast/professional end of the home user market.

We have only briefly
skipped through some of the features of this application. PlexTools Professional
XL has many more options for the enthusiast/professional home user to
investigate. 

The way in which
PlexTools Professional XL displays its diagnostic data is awesome; apart from
Plextor's own PlexTools Professional, there is no other diagnostics application
that comes even close.

Is it worth paying extra
for the XL version? Yes is the answer in my opinion.

We will now round of
this review with some advanced tests on the Plextor PX-755A on the next
page…….

---

The
'Sheep Test":

To round off this review,
we will run some advanced tests on the Plextor PX-755A. These tests are: 'Sheep
Test", protected audio discs and some special disc tests.

For this test, we
will use the Sheep tests made by Alexander Noé. Why is
it called sheep test? That's because the logo of the first 1 to 1 copy program
called CloneCD is a sheep. When
looking at supported writers, you will notice that the feature list has sheep to
indicate if a feature is supported or not. In this case we are interested
in the writer's ability to backup/write weak sectors.
Also called: 'Correct EFM encoding of regular
bit-patterns".

• No
  sheep: Can't backup any safedisc 2 versions
  without the help of software tricks
  
• 1 Sheep: Can backup
  safedisc 2 up to version 2.4x without software tricks
  
• 2 Sheep: Can backup
  safedisc 2, including version 2.5x
  
• 3 Sheep: Can write all
  possible weak sectors, few if any writers could do this.

One of our forum
moderators Womble, has written a guide concerning
the 'Sheep Test" that can be found here.

In the screenshot below
taken from CloneCD, we see the Plextor PX-755A supports most features but not
all.

The Plextor PX-755A
supports DAO-RAW96 recording mode, which basically means, it can write
uncorrected data and sub-channel data.

 

As we can see from the
table the Plextor PX-755A is a 'No Sheep Burner", and would not be suitable for
reading protected discs without using some software tricks.

Copy
protected Audio:

For our protected audio
test, we used the Exact Audio Copy program. We inserted the protected audio
discs and if the drive was able to recognize the disc we tried to extract the
music tracks to the hard drive. First let us look at the discs we had available
for this test: 

Celine Dion: A New Day
Has Come; protected with key2audio version 3.

 

Herbert Gé¶nemeyer: Mensch
- This disc is protected with Cactus Datashield 200.0.4 .3(build 12b)

And Michelle: Leben!;
protected with Cactus Datashield 200.5.1.91 '“ 5.10.090.

Results:

From our 'copy protected
audio disc" tests, we would have to conclude the Plextor PX-755A is a useful
drive for ripping protected Audio CD's

Overburning:

CD-R
900MB (99 minute) over-burn test:

For this test we used an
Infiniti Professional Compax 99min/900mb CD-R. (Thanks to Medea International
(UK) for providing the disc).

From the screenshot
above, it was clear the Plextor PX-755A should be able to write the 99 minute
media at up to 102 minutes and 10 seconds. We then set up a test over-burn with
Nero CD-Speed. We set the test at 102:00.74 to be exact, and then attempted to
write a test disc.

The Plextor PX-755A
successfully created our test disc. We then tested to see if the Plextor PX-755A
could read our created disc. As you can see from the screenshot below, the
PX-755A could read the disc up to 92 minutes then failed.

DVD+R
over-burn test (4600MB):

For this test we used a
Plextor branded Taiyo Yuden 16x DVD+R media. (Thanks to Plextor for providing
this media)

The Plextor PX-755A
reported the maximum over-burn capacity was 4.38GB. We however attempted to
create a data disc with a capacity of 4.6GB using CD-DVD Speed.

The burn failed at
4.38GB, and we have to conclude the Plextor PX-755A can not over-burn DVD+R
media.

GigaRec:

One of the nice features
of the Plextor Premium series drives, is that they support GigaRec. But what is
GigaRec? GigaRec lets you change the recording capacity of a standard CD-R disc
from 70 percent up to 130 percent of its standard capacity.

In this test we used
PlexTools Professional XL and a Verbatim CD-R media rated at 700MB (80 minutes),
and attempted to write 888.47MB of data to the disc with GigaRec
enabled.

GigaRec enable/setup screen

First of all we enabled
GigaRec and set the (rate) to 1.3x

Our compilation screen

As we can see from the
above screenshot, we dragged and dropped 888.37MB of data into the 'Disc Maker"
window in PlexTools Professional XL.

Write dialog

We then set the options
for our burn; GigaRec only allows 8x maximum writing speed.

Burn completed successfully

As we can see from the
above screenshot, our burn completed successfully at 8x. We then tried to read
the disc with the Plextor PX-755A.

Read back test

As we can see in the
above screenshot, the Plextor PX-755A had no problems in reading back our test
disc.

Mini
DVD-RW discs:

In this section we are
going to test if the Plextor PX-755A is capable of writing and reading mini
DVD-R/RW discs with a capacity of 30 minutes/1.46 GB.

The Memorex media is made by CMC
Magnetics.  Thanks to Memorex Europe for sending us this media.

As we can see, the
Plextor PX-755A had no problems in writing to our MINI DVD-RW disc.

Now it was time to test
if the Plextor PX-755A could read our disc.

The Plextor PX-755A had
no problems in reading the created MINI DVD-RW disc.

The Verbatim MINI DVD-R
was manufactured by Mitsubishi Chemicals Corporation. Thanks to SVP UK for
providing this media.

Now it was time to see if
the Plextor PX-755A could write our MINI DVD-R disc.

The Plextor PX-755A had
no problems writing our MINI DVD-R disc. Now let's see if the drive can read
back the disc.

The Plextor PX-755A
successfully read back our MINI DVD-R disc.

Video-CD
disc:

For our final test we
wanted to see how the Plextor PX-755A would read a Video-CD, for this test we
created a Video-CD with Nero Burning ROM 6, and used NERO CD-DVD Speed to read
the disc back. Below is our result:

The Plextor PX-755A is
locked at 40x when reading VCD discs. The Plextor PX-755A had no problems in
reading our test VCD disc.

This concludes our
Plextor PX-755A review, let's head on to the last page to read our
conclusion…

• Failed our 'Sheep
  tests" 
  
• Attempts to over-burn
  DVD+R media were unsuccessful

Conclusion:

Let us summarize
the most important positive and negative points below:

The main
positive points:
The Plextor PX-755A can write most DVD±R with very good quality. PoweRec and
Auto Strategy assured the best results possible over our large range of tested
media.

CD-R/RW write quality was
also very good, the Plextor PX-755A handling some troublesome media with ease.
CD-R/RW media compatibility was also very good.

The supplied software is
also of very good quality, with PlexTools Professional supplied with the drive.
Also included is the ever popular Nero suite, and Pinnacle suite 8.3 LE. 
This should provide enough software for the beginner and the more advanced user.
There are also trial versions of many other software packages, which will allow
the end user a chance to try out software before they buy it.

The Plextor PX-755A also
runs quiet and cool. This could be important if the drive was used in the main
living area or bedroom, and running cool could become important if the drive was
to be used in a hot climate or cramped PC case.

The build quality of the
Plextor PX-755A is of a very high standard, the media tray being very smooth in
operation, and the drive itself feeling very well built.

The media testing
capabilities of the Plextor PX-755A is second to none, with PlexTools
Professional/XL providing the most sophisticated media tests yet seen on a home
user drive.

Last but by no means
least. The 2 year collect and return warranty (within the EU) is the best
around.

The main
negative points:  Every drive has its weak points,
and the Plextor PX-755A is no exception.

Some work is required to
improve DVD+R DL write quality with certain DVD+R DL media.

The Plextor PX-755A
performed very poorly in our 'Sheep tests". Let us hope this can be improved
with a firmware update.

Although the drive is
said to be able to over-burn DVD+R media, all our endeavours to over-burn this
media type were not successful.

To sum it
all up, this is
what we would say: 'The Plextor PX-755A is
a very sophisticated and good performing drive". A few areas need
attention, but overall the drive works extremely well.

By using our price
grabber feature cdfreaks.pricegrabber we were
unable to locate a listed price for the Plextor PX-755A, however we found one UK
online retailer had the retail drive listed for £69.14 UK pounds including VAT
(March 2006).
