hi there, i have 3 hds in my mac pro: 250 original hd 300 gig hd 500 gig hd would you suggest to raid these hds? i would like atleast the 250 and 300 raided. for now, i just cloned each drive with leopard for back up, which seems kinda pointless to me. but just to be on the safe side. any help would be appreicated. thanks!
