I've searched the forum here and have found recommendations but also some warnings on all the 1TB HD's for the Mac Pro. So basically I'm coming here to ask probably a very redundant question because I'm still unsure as to which drive I should buy to add to my Mac Pro. Barracuda? Caviar? Hitachi? I'd much rather buy one that's below 250.00, so if that changes any opinions, there ya go.
