reviewed (and subsequently adored), along comes revision two. The RevoDrive X2 PCI-Express SSD looks, feels and smells the same as the first, but the performance is obviously looking north. The unit we saw introduced at Computex was capable of hitting 540MB/sec, while the X2 pushes that to 740MB/sec and up to 120,000 IOPS -- "nearly triple the throughput of other high-end SATA-based solutions." Furthermore, this guy packs double the SandForce SF-1200 controllers (four versus two in the original), and it retains the onboard RAID 0 design that you've come to know and love. It's available as we speak in 100GB to 960GB capacities, but there's nary a mention of price; something tells us that you're probably not the target market if you have to ask.
