OCZ Storage Solutions, now part of the Toshiba Group today announced the introduction of the enterprise-class Z-Drive 4500 PCI Express (PCIe) SSD Series. The new Z-Drive 4500 Series uses 19 nm MLC NAND flash and is available in capacities of 800GB, 1.6TB and 3.2TB. The drives are all in the Full-Height / Half-Length (FHHL) form factor and come with a 5 year warranty.
Each model within the Z-Drive 4500 Series is integrated with OCZ’s new Windows Accelerator (WXL) Software, a flash management and caching solution for Microsoft Windows Server applications also announced by OCZ today. WXL Software should enable IT managers to deliver low-latency flash deployable as a local flash volume, a flash cache for HDD volumes or as a combination of both.
When deployed for caching, WXL Software performs statistical ‘out-of-band’ processing to cache the most frequently accessed data on Z-Drive 4500 flash. A cache warm-up and analysis mechanism is also featured to assure that critical data is available to the application at the exact time it is needed.
The new Z-Drive 4500 Series are driven by OCZ’s proprietary Virtualized Controller Architecture (VCA) and LSI SandForce SF-2582 SSD controllers. Based on SNIA test methodologies, the series delivers a maximum read bandwidth of up to 2,900 MB/s, maximum write bandwidth of up to 2,200 MB/s, random 4K block read throughput of up to 252,000 input/output operations per second (IOPS) and random 4K block write throughput of up to 76,000 IOPS.
The Z-Drive 4500 Series also feature power-loss data protection, end-to-end data path protection that performs data integrity checks at every data juncture ensuring that corrupted data is detected and not propagated, 128-bit AES encryption that complies with industry standard data security, TRIM command support that enables data pages to be overwritten and re-used and temperature sensing and thermal throttling for maintaining consistent operating conditions so drives can continue to function through adverse temperature variances
They are come in new SSD casings for providing a more stable and thermally efficient environment, come with complete rebuild of the Linux and Windows kernel device drivers from the Z-Drive R4 platform, optimized to improve SSD performance and stability and installation drivers are packaged with RedHat Package Manager (RPM) and Debian (DEB) package files to automate the installation process.
