When you first insert the disk (with Autorun enabled) you will get the Languange Selection screen.

The Menu Selection screen shows three options: Application Install (Nero install), Manual (electronic version of User's Guide) and User Support Web Page (links to Sony and Nero AG). Next we select the Manual button.


We would like to note that the electronic version of User Guide is less comprehensive than the printed version of Operating Instruction. Now let's continue with Nero installation.


Nero StartSmart shows a list of Nero applications that are installed. Nero Burning ROM version that came with the disc was 6.6.0.12 and we upgraded to version 6.6.0.16 without any problem. We also upgraded NeroVision Express 3 from version 3.1.0.7 to 3.1.0.16 and Nero Media Player version 1.4.0.29 to 1.4.0.35.

The software identifies as Nero 6 Sony Edition.
Turbo Boost Function:
The default CD-R and CD-ROM read/write speed of the Sony DRU-810A is 40x speed. With a single touch, you can activate the Turbo Boost function, to raise the read/write speed to 48x speed:
⋅ Insert a CD-R/CD-ROM disc into the drive
⋅ Press and hold the Eject button for five seconds.
The busy indicator blinks twice and the read/write speed switches to 48x. (The Turbo Boost function is active.)
Note: When you open the disc tray, the Turbo Boost function will be deactivated.
Write Technology:
Now it's time to take a closer look at the write technology used by the Sony DRU-810A:
CD-Recordable:

The Sony DRU-810A uses CAV, (Constant Angular Velocity), to write at its maximum speed of 48X (Turbo Boost function activated). This gives an average speed of 34.77x. Two drives for comparison are found below.

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 in four zones. The drive wrote the last zone at 40.41X and this gives an average speed of 31.70x.

16X DVD+R/-R Writing speed:

The Sony DRU-810A uses CAV (Constant Angular Velocity) to write DVD+R at the maximum supported speed of 16x. This gives an average write speed of 11.55x and a writing time of 5 minutes 43 seconds.

The Sony DRU-810A uses CAV (Constant Angular Velocity) to write DVD-R at its maximum speed of 16x. This gives an average write speed of 11.38x and a writing time of 6 minutes and 9 second.
Below are some write graphs from some other drives for comparison.

The Pioneer DVR-110D uses CAV (Constant Angular Velocity) to write DVD+R at the maximum supported speed of 16x. This gives an average write speed of 11.58x and a writing time of 6 minutes 9 seconds.

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.

From the table above, we can see that the Sony DRU-810A is among the fastest drives in writing DVD+R and DVD-R.
8X DVD+R DL writing speed:
The Sony DRU-810A supports 8x writing speed on DVD+R DL media.

The Sony DRU-810A uses P-CAV (Partial-Constant Angular Velocity) to write DVD+R DL at 8x. The average speed is 7.18x and total writing time is 15:52 minutes. Very fast!
4X DVD-R DL writing speed:
The Sony DRU-810A supports 4x writing speed on DVD-R DL media.

The Sony DRU-810A uses P-CAV (Partial-Constant Angular Velocity) to write DVD-R DL at 4x. The average speed is 3.76x and total writing time is 29:47 minutes. Pretty slow in this area considering other new drives can write DVD-R DL up to 8x speed (ie. Pioneer DVR-110D).
8X DVD+RW writing speed:

The Sony DRU-810A uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+RW at 8x. The average speed is 7.64x and total writing time is 7:40 minutes.
6X DVD-RW writing speed:

The Sony DRU-810A uses CLV (Constant Linear Velocity) to write DVD-RW at 6x. The average speed is 5.92x and total writing time is 10:19 minutes.
Book type (bitsetting):
The Sony DRU-810A supports bitsetting, and as default will write DVD+R, DVD+RW and DVD+R DL media with DVD-ROM book type.

With Nero CD-DVD Speed, we can see in the "Book Type" column in Drive Settings area that all disc types are currently bitset to DVD-ROM. When a disc is inserted in the drive, the Disc Settings area will show the Book Type. Screenshot above shows that there is a DVD+R DL disc in the drive tray and it shows that "Current book type" is set to DVD-ROM.

When you insert a DVD+RW disc, the "Set" button is available and we can change the Book Type without having to re-burn the disc.
Another way you could check if your discs are really written with DVD-ROM Book Type is by observing the Disc Info tab. You should see something similar to the following:

The Sony DRU-810A is among the fastest drives in writing various kind of CD and DVD media compared to other drives. Our tests shows that the drive is able to reach the specification write speed easily. The only downside is the support of DVD-R DL at 4x write speed where we can find other new drives that supports this type at 8x speed (ie. Pioneer DVR-110D).
Let's continue to the next page where we will examine the reading performance...
The specifications of Sony DRU-810A state that the drive is able to write CD-R discs at 48x with Turbo Boost activated (see page 2). Let us find out how the drive really performs in speed and quality.
Writing Quality with CD-R discs:
For our data writing tests, we simply set up a new compilation of about 700Mb 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 3 minutes and 1 seconds to write the disc at 48x. Let us see how this compares to other drives:

Write Quality:
We will test CD-R discs from a total of 6 different CD-R manufacturers. To really measure the write speed, we used the 'create data disc" function in Nero CD-DVD 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 LTR-40125S drive with firmware ZS0R 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 quality discs, or at least below 10.0 C1 average for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.
In short, our analysis will be based on these guideline to determine the quality of the burned disc:
CD-R/RW quality scan guideline
| Average C1 | C2 | Quality |
| 2 and lower | 0 | Best |
| 10 and lower | 0 | Good |
| Above 10 | exist | Poor |

Writing Quality with CD-RW discs:
Due to requests from our readers, we will add a few write quality tests with re-writable media. Settings and testing procedures is 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 are new and have not been written to before.

The Sony DRU-810A is an exceptional CD-R Writer that will write quality CD-R media with excellent results. Surprisingly the drive does not support its own Sony media very well, i.e. would only write at 32x speed with average write quality. The drive's performance is a lot different if we take a look at CD-RW part. On all CD-RW media we have tested, the writing quality is really poor. Sony should take a look at this area and improve support for CD-RW media in its next firmware upgrade.
But nevertheless, it's a DVD-Writer, so head on to next page and read about DVD-Writing performance and DVD media compatibility…
DVD-R media write quality:
In these tests we will be using a Lite-On SOHW-1693S drive with firmware KS0A along with K-Probe to measure the disc quality. We will also be using the Sony DRU-810A itself with firmware 1.0a for our read-back tests.

In the area of DVD-R, the Sony DRU-810A is quite optimized to burn high quality DVD-R and DVD-RW media with good to excellent results. There are some issues with media compatibility, i.e. OptodiscR016 and RITEKF1 are not supported at their certified write speed. Sony should investigate on these issues. We also hope that Sony would support overspeeding in future firmware, especially for higher quality media.
Head on to next page and read about DVD+R DL and DVD-R DL compatibility and write quality...
To round off this review, we will run some advanced tests on the Sony DRU-810A.
The 'Sheep Test":
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 Sony DRU-810A supports everything.

The Sony DRU-810A supports DAO-RAW96 recording mode, which basically means, it can write uncorrected data and sub-channel data.
| Sheep Tests | Reader: NEC 3540A |
| One Sheep Burner SD2OLD |
Yes |
| Two Sheep Burner SD251 |
Yes |
| Safedisc v2.90 SD290 |
No |
| Three Sheep Burner SHEEP3 |
No |





As we can see from the table the Sony DRU-810A is a 'Two Sheep Burner", but it however failed to write the Safedisc V2.90 and Sheep3 tests.
CD-R Overburning test:
To test the CD-R overburning capabilities of Sony DRU-810A, we used the overburning test in Nero CD-DVD Speed. According to Nero CD-DVD Speed the drive can overburn disc larger then 99/100 minutes. For this test we used unbranded Infodisc 99min/900mb CD-R which is rated 10x speed.

The Sony DRU-810A reported an overburn capacity of 99 Minutes and 57 Seconds, so we attempted to created a test disc slightly smaller then the max reported overburn capacity. See below:

There are no problem writing this media around 99 minutes. We now ran a transfer rate test to check the created discs readability.

The Sony DRU-810A read the disc up all the way to the end without any error. We conclude that the Sony DRU-810A supports overburning 99 minutes CD-R.
DVD+R Overburning test:
To test the DVD+R overburning capabilities of the Sony DRU-810A, we used the overburning test in Nero CD-DVD Speed

According to Nero CD-DVD Speed the drive can overburn DVD+R disc up to 4649MB. The media we use is Fujifilm's with code YUDEN000T02 8x certified speed. However for this test we attempt to overburn 4600MB (4.49GB). Let's see how the drive performs.

There are no problem writing this media up to 4600MB or 4.49GB. We now ran quality scan on a Lite-On 1693S and BenQ 1640A, as well as transfer rate test to check the created discs readability.



The Sony DRU-810A writes the overburned disc with high quality and the transfer rate test looks excellent. We conclude that the Sony DRU-810A supports overburning 4600MB DVD+R.
This concludes our Sony DRU-810A review, lets head on to the last page to read our conclusion…
Positive:
- Comprehensive retail bundle and includes extra black bezel
- Feature-rich software package suite from Nero
- Very good specifications
- Excellent DVD+R/-R writing and rewriting quality
- Excellent DVD+/-R DL writing quality
- Very good CD-R writing quality
- One of the fastest drive for writing DVD+R DL media.
- Drive has no riplock, reading speeds are not limited.
- Supports bitsetting for DVD+R/RW/R9 DL
- Very good and fast reader
- Reads DVD+/-R media at 16x and DVD+/-RW media at 12x
- Reads both pressed and recorded DL media at 12x
- Drive runs quietly
- Small form factor for small footprint desktop cases
- 'Two Sheep" writer
- Supports writing/reading 99 minutes CD-R media
- Supports overburning 4600MB DVD+R media.
Negative:
- Small 2MB buffer
- Does not support Mt. Rainier
- Does not support overspeeding 8x DVD+/-R media to 12x or 16x speed
- Poor CD-RW writing quality
- 16x DVD+R writing creates PIE/PIF spikes near the end of the disc
- 8x DVD+RW and 6x DVD-RW media compatibility needs improving
- Limited 4x DVD-R DL writing speed while other drives offer 6x and 8x
- Some 16x DVD-R media burns at lower speed than its rated speed
- Turbo Boost (48x CD-R/ROM read/write) is disabled by default
- Does not support disc quality (PI/PO) checking as well as superior features found in QSuite for BenQ 1640.
Conclusion:
Let us summarize the most important positive and negative points below:
The main positive points: Following our extensive tests we found that this drive is a very solid DVD burner with nearly no noticeable issues. It is bundled with a complete and fully functional software suite from Nero which is worth the extra price. The documentation is also satisfactory and you will also get an extra black bezel to match your desktop case color.
Sony seems to be very cautious with media compatibility, that is to say, the drive supports the majority media at its rated speed, although consequently the writing quality for all formats is very good to excellent with most media types we've tested. The reading capability is also worth noting; since the drive has no riplock therefore it offers very fast reading speeds. It is able to read DVD+R/-R and single layer DVD-Video format at a maximum speed of 16x and all other DVD types (DVD+/-RW/DL) at an efficient speed of 12x, while other competitors are still struggling with 8x or even 4x.
In our DAE quality test it shows that the extracting quality is excellent and it supports reading the lead-in and lead-out. The Advanced Tests specify that the Sony drive can be categorized as a 'Two Sheep" writer, which implies that it should be sufficient for backing up copy protected discs. The drive also supports overburning 99 minutes CD-R and 4600MB DVD+R which can be valuable for power users. Overall, given that the drive is based on highly rated BenQ DW1640, the Sony DRU-810A belongs in the best drives category.
The main negative points: There are few minor issues that we would like to mention in this section. The drive writes all 8x DVD+R and DVD-R media at its rated speed only. We have seen its outstanding performance on 8x writing and consequently we have no hesitation that overspeeding media will also perform nicely. After all, we notice that the drive does overspeed Verbatim 2.4x DVD+R DL at 8x with great result. We would like to see some overspeeding in future firmware updates, especially for high quality media.
The drive creates high PIF error spikes when writing 16x DVD+R media at its certified speed, although fortunately this anomaly doesn't seem to create read-back problems. In the area of media compatibility we also would like to suggest some improvements. There are a few *average quality* media that will not write at its rated speed either because they are not supported by the current firmware or OPC is too sensitive: CMCMAGM01 16x DVD+R, OPTODISC R016 16x DVD-R, RITEKF1 16x DVD-R, and RITEKP01 DVD-R DL 4x to name a few.
During our CD-R and CD-RW test we acquire a few minor issues. The drive will only write its own Sony 48x CD-R media at 32x speed although it might be due to the oversensitive OPC feature. Regrettably as in many other DVD drives, CD-RW writing quality is really poor showing the presence of C2 errors, which are not wanted. Finally, a slight issue that we feel needed to mention is the Turbo Boost function, which is deactivated by default. This means that without pushing the eject button for five seconds every time we need to read or write a CD, the drive will not reach 48x as stated in the specification.
Final Thoughts: The Sony DRU-810A is only a fraction behind its associate BenQ DW1640. Suffice it to say, it is 'A superior drive that can achieve high performance results in nearly all areas of DVD and CD burning today and undoubtedly will not let you down." We would like to present this drive our 'Safe Buy" award.

By using our CD Freaks price grabber feature we found the Sony DRU-810A is listed at $69.99 after rebate (October 2005).
