I wouldn't recommend to anyone to RAID 74g WD raptors. I know because i've had them RAID 0 before. The only advantage you get out of that is double the space in 1 drive letter @ 10,000rpm. Also, at double the cost. The performance that you get from a (2) WD raptor in RAID 0 vs. (1) WD raptor isn't noticable "AT ALL". I know this for a fact because I used to have this RAID array and now i only have 1. You can't tell the difference. Only in drive size.
