Solid-state drives seem destined to shed their Serial ATA interfaces. The tide is already beginning to turn in enterprise, where PCI Express provides considerably more bandwidth than SATA or SAS links. To cater to that market, OCZ has announced a new member of its growing PCIe SSD family: the VeloDrive.
This low-profile card sports a PCI Express 2.0 x8 interface and no fewer than four SandForce 1565 SSD controllers. The SandForce chips are linked together by a RAID controller, but there’s no mention of whether it uses the same proprietary Virtualized Controller Architecture as OCZ’s Z-Drive R3. OCZ does note that the VeloDrive can be configured with hardware or software RAID stacks, though.
The VeloDrive will be available in 300GB, 600GB, and 1.2TB capacities built on MLC NAND. As one might expect, the drive’s performance specifications are rather impressive. The VeloDrive is said to be capable of hitting maximum read and write speeds of 950 and 1000MB/s, respectively. Take that, 6Gbps SATA.
Update: OCZ has confirmed that the VeloDrive does not use VCA, which is currently being refined on the Z-Drive R3.
