Hey im about to make a purchase with my hard earned money so i wanted to make sure i was getting the best.

which one would be faster & better serve me?

1x western digical velociraptor 300g 10,000rpm http://www.newegg.com/Product/Prod [...] 6822136260

2x seagate barracuda 250g 7,200 rpm http://www.newegg.com/Product/Prod [...] 6822148262

also, what would be some good raids for the option of having two seagate barracudas?

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.

The Velociraptor will be noticeably faster in almost all apps, due to the faster access time.

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.

Raid doubles the sequential data rate. However, it does not improve random access time. This is an area in which the 10k is always faster.

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.
