I am using Supermicro CSE-M35S SCA SCSI U320 drive enclosures on SCSI RAID. They hold 5 SCSI hard drives in 3 x 5.25" bays. They are hot swap and fail over ready. Do they make similar enclosures for WD Raptor 74GB NCQ drives? I was considering getting a 3Ware 9650SE controller and setting up 5 drive RAID 5 with a spare.
