OCZ Technology has just announced two new PCI Express x4 solid state drives, the RevoDrive 3 and RevoDrive 3 X2, that use the company's recently introduced Virtualized Controller Architecture (VCA) 2.0 technology and can reach capacities of up to 960GB.
These are the first drives to use the second iteration of the VCA technology, which was developed in order to increase the performance of multi-controller SSDs.
Its main advantage over the regular RAID 0 internal setups, used by most other PCIe solid state drives, is that it enables the operating systems to use the TRIM command in order to wipe blocks of data which are no longer in use.
Furthermore,
VCA 2.0 also adds support for the creation of a virtual pool of logical units (LUNs) as well as for the SCSI Unmap command.
The RevoDrive 3 will be available in 240GB and 480GB capacities and, according to
OCZ, it can deliver sequential read and write transfer speeds of 1GB/s and 925MB/s, respectively, while the maximum 4K random write performance is rated at 230,000 IOPS (input/output operations per second).
Its older brother, the RevoDrive 3 X2, will be available in 240GB, 480GB and 960GB capacities, and features a similar IOPS performance, but sequential read and write speeds were raised to 1.5 and 1.25 GB/s, respectively.
"OCZ RevoDrive 3 PCIe
SSDs use our VCA 2.0 technology to deliver superior performance and functionality for everything from scientific computing to high availability clustering," said Daryl Lang, vice president of Product Management of OCZ Technology.
"This exciting new workstation-class storage product accelerates application performance and takes full advantage of today's multithreaded processors and software, providing customers with greater throughput in an easy-to-deploy, single card solution," concluded the company's rep.
OCZ Technology hasn't revealed when the two drives become available, or their recommended retail price.
