I want to upgrade our homemade server at work and I have to decide whether to go SATA or SCSI. Currently I'm using 1 36 Gig and 1 72 Gig SCSI drive NOT in RAID. I have an additional 72 Gig drive waiting in the wings and a 36 gig that needs repairing. I would be replacing the MB at the same time anyway, so I could easily use the onboard SATA RAID controller. If I don't go that way, I would have to buy a SCSI controller. The use is a very large database that is accessed 24/7 on both read and writes, so I was thinking of either RAID 3 or 5, and at the minumum RAID 1. SATA seems like a great deal but what about the throughput?
