I've heard a lot of mixed opinions on RAID. Some people say it's great, and some say it's not worth the money. I would say that that the majority of people would say to use RAID 0 with 2 80GB hard drives.
On a side note, I just purchased a 36GB Raptor and it's very silent. It could be due to my 4 case fans and large heatsink/fan.
