Hmm, I was going to suggest RAID 5 with SCSI as we have a few monster computers out here at work with about 3 300Gig SCSI HDD's in RAID 5 and 1 400Gig HDD for Windows

,you would not believe how fast these things go, if it wasn’t for the 30 second wait at boot while the RAID controller started up, Windows could load in about 10-15 seconds.
Then again, they do have Dual Xeon 3.8's in them with 16 Gig of RAM [img]tongue.gif[/img]
So yeah, I would suggest getting SATA drives, so long as you have a motherboard that supports more than 2 you should be fine, it really depends on how much storage you want, 3 250Gig HDD's is ALOT of space, and I doubt you will ever need that unless you intend to hire every DVD in your local video store and start ripping now
