Worth considering other cheaper but still good drives though (Falcon, Agility (may not be out yet but should be good but cheaper than Vertex) or Samsung. Or if you're a games whore and need lots of OS/programs space, two Corsair S128, probably RAID0 (transfer rates important for working with big files, but even the Corsair S128 with slower transfer speeds - they are sufficient to not bottleneck general OS use because IOPS matter too. RAID0 benefit remains debatable - some say it helps, others don't, up to you.)
