OCZ Launches New RevoDrive 3 (X2)
OCZ has launched its latest PCIe solid state drives for the enthusiast consumer market, the RevoDrive 3 and RevoDrive 3 X2, along with promises of exceptional performance. The new lineup is based on the latest SandForce controllers (SandForce-2281)–two or four of them working in an internal RAID 0 configuration to boost performance. TRIM support is also present and the speeds offered are up to 1.5GB/s and 230,000 IOPS.
OCZ is focusing on the most demanding consumers with the RevoDrive series–the main difference between the two new models is that the RevoDrive 3 uses two controllers, which the X2 version comes with four SF-2281 controllers to achieve even higher performance. The capacities range from 240 GB to 960 GB.
The big news with RevoDrive 3 is called VCA, Virtualized Controller Architecture, which uses a proprietary SAS RAID circuit that divides the data and sends different parallel I/O to the various controllers. This makes it possible to get the same performance as with RAID, while maintaining support for TRIM.
The problem remains that TRIM in Windows 7 has a well-known limitation that prevents it from issuing the TRIM command over any SCSI/SAS controller and this is a problem only Microsoft itself can solve. A solution is expected in the next generation Windows Server, but when the TRIM command will operate on the RevoDrive 3 together with Windows 7 is still unclear.
It is said to
work with most Linux distros, as long as it is capable of sending out the TRIM command to a SCSI / SAS controller. None of the units are available on the market at this writing, but the price for RevoDrive 3 X2 will be $ 699.99 (240 GB), $ 1699.99 (480 GB) and $ 3199.99 (960 GB).
