[QUOTE="martyp, post: 703402, member: 61183"] I setup a RAID0 on the last PC I build with two 160Gb 7,200rpm drives giving 320Gb space. Now to setup a RAID the drives have to be (or very close) to identical ie. Same size space, cache, bus speed, spindle speed & manufacturer. You cannot setup ANY RAID array with three different sized drives - unless Mac RAIDs are different from PCs although I doubt it. Since HDD's are so cheap now a days, I'd recommend buying 3x 500Gb drives and going for RAID5 (speed and redundancy), but if you don't want to buy a RAID card and the Mac Pro supports (RAID0/1) I'd get 2x 1TB drives and RAID1 'em - this way if one goes down you've got a back up and it also 'theoretically' doubles read speed. You could use one of your older drives for a scratch disk. HTH. [/QUOTE]
