Hey all, i'm planning on buying a 2TB SATA drive for my octoPro. When I bought the Mac Pro last week I read that the machine recognizes 4TB of hard drive space. I want to know if I should buy a 2TB drive and if it will be recognized. I also know they have the 1.5TB drives...do those work? If not, then I'm left to buying the 1TB Black Caviar. Thanks in advance for any information!
