5 year warrenty.. You're forgetting the Raptors are using SCSI mechanical parts with a cheaper SATA interface controller. The interface is the only difference between them and SCSI disks in 10,000RPM catagory. I have two and I've had them for a year, and I havn't given them much resting time, still havn't died on me.
I don't have anything against SCSI, in fact if I had more money than sense I'd use it on every machine in this house. SCSI is very mature, and pretty much perfect for demanding disk I/O, but that doesn't change the fact that it costs a small fortune.
I just wish you'd stop blabbing unsubstantiated nonsense all the time, back in real world (tm) people buy SATA products because its a good ballance of price/performance, and Linux actually doesn't suck when you know how to use it.
