The RevoDrive PCI-Express SSD from OCZ uses multi-level cell (MLC) NAND flash and is targeted at consumers–or more precisely enthusiast consumers and client workstations that require both performance and relative affordability. Since it uses the PCIe interface, it removes the SATA bottleneck and offers sequential read speeds of up to 540MB/s as well as 75,000 IOPS in random 4k writes.
OCZ has used dual SandForce controllers similar to the ones found in their Vertex 2 2.5-inch drives, but in this case two controllers are used in an internal RAID 0 configuration to achieve these high speeds.
OCZ’s RevoDrive can be uses as a boot drive and is available in capacities ranging from 50GB to 480GB:
- 50GB – OCZSSDPX-1RVD0050
- 80GB – OCZSSDPX-1RVD0080
- 110GB – OCZSSDPX-1RVD0110
- 120GB – OCZSSDPX-1RVD0120
- 180GB – OCZSSDPX-1RVD0180
- 230GB – OCZSSDPX-1RVD0230
- 240GB – OCZSSDPX-1RVD0240
- 360GB – OCZSSDPX-1RVD0360
- 480GB – OCZSSDPX-1RVD0480
There is some variation in read/write performance between different capacities; the 50GB and 80GB drives are capable of read and write speeds of up to 540MB/s and 480MB/s respectively (350MB/s sustained write), the 110GB drive is capable of 530MB/s read and 435MB/s write, the 230GB drive can read and write at up to 530MB/s and 450MB/s, while the 120GB to 480GB drives are all capable of reads/writes of up to 540MB/s and 480MB/s respectively (400MB/s sustained write).

Reviews:
Despite there being little improvement in regards to random read or write performance, we were surprised to find the Revo was conclusively two seconds faster than a standard SandForce drive when loading games.
OCZ has really outdone themselves as the RevoDrive is probably the best bang-for-your-buck SSD purchase you can make right now.
