In all honesty, if you can - Raid 0 these drives:

It'll cost $460, but it's insane just how fast it is.

I recently built an i7 rig, and RAID 0 these drives, here's my results:

- Installed windows in literally 10min. ( it was unbelieveably fast )
- The drives are dead silent. Even quieter than my other 7200rpm ones.
- Installed WoW ( regular, BC, and Wotlk ) in about 15min.
- I click "down" on my mouse button to launch something, it's usually open before my mouse button comes back "up"... Im seriously not joking.
- Things load in WoW ( the loading bar ) in 1-2 seconds max.


I upgraded everything on my computer... Added 12gb ram, added a gtx 260, etc etc... and the biggest difference in performance were these HDD's, its insane how fast they are.
