You probably know about the OCZ RevoDrive which has amazing IOPs. At the Sandstorm booth at IDF technology Showcase, the latest RevoDrive x2 is sighted at the Sandforce booth.
The new OCZ RevoDrive X2, which is a PCI Express-based SSD that features four Sandforce controllers in what’s essentially a 4-way RAID configuration looks just like the the existing RevoDrive, but with a daughterboard attached with two additional controllers and some additional NAND. The RevoDrive X2 also sports Intel NAND flash memory. The device offers a max read speeds in the 740MB/s range with writes approaching 730MB/s. Using IOMETER, 4K random writes are rated at up to 120,000 IOPS.
