it really all depends what you want to use it for. But ive heard that a 7200rpm SATA drive is fast enough nowadays that you dont need a 10000 rpm SATA drive. But i dont know what other features the velociraptor has that makes it better... If you desire security, raid 1 is good, if you want speed raid 0 is good. But thats just what i learned from wikipedia.
but,2 HD driver=double space &RAID .RAID0 can offer better performance RAID1 can make sure your data safely,even 2 hd driver will make u pay more $,but i think that be must.
It's said that a single velociraptor is about as fast as 2 of the older 160 raptors in raid 0. this is because of the 10,000k rotation and that is uses laptop drive size platters. (smaller platters = less movement on the read/write head which = better performance. ) 2 of the older seagate 250 gig drives will not be able to keep up even in raid 0. To come close you would need larger drives (1TB) cuz the data will be more tightly packed together.

Both the old Raptors and the new Velociraptor use 2.5" platters, as do all 10K RPM drives. The access times for the old Raptors and the Velociraptor are approximately equal.
The Velociraptor has higher bit density on each platter, which gives it the higher transfer rates.
