I work with Raptors at work and yes the warrenty is sweet (5years). The performance is great, however. . . The 150GB one will cost you the same as 2 larger SATA drives. Maybe you can pick a raptor up for about 220, but you can get 2 x 320GB SATA with 16MB Cache for less than that price. Performance should be somewhat comparable with RAID 0 and your getting 600+ GB instead on 120 something after the thing is formated and winblows is on it. If you have built in SATA RAID on the motherboard, there are a TON of articles on how to setup and install an OS on it. Thank you Google.
