15k drives with RAID

[flying.squirrel]

early MacPro 3,1 with RAID card and 2 15k rpm drives. Want to toss this RAID card so bad. Sorry I ever got it. That being said, if I yank out the RAID card can I still use the two 15k drives? One for OS and other for Logic, say? I'm assuming there are cables connecting each to RAID? How would I re-connect them to my motherboard? Thanx! - robert

Yes you can still use the drives. I thought the Apple RAID card enabled RAID through the backplane to the standard drive bays, meaning there are no cables involved. So I believe all you have to do is remove the card, boot to an OS installation disk, wipe the drives, and install a fresh OS on one of them.

That's true on 4,1 & 5,1.

The 1,1 - 3,1 drive bays are connected to the logic board via an sff-8087 cable. When using a raid card, this cable is moved to the raid card, and needs to be moved back to the logic board after removing the card.

Nice tidbit of knowledge there, thanks.

The native ports on the cMP are SATA-II while those 15K drives are almost certainly SAS so they will work directly connected to the Mac motherboard.
