Can anyone give me advice on which portable hard drive to buy. It needs to be 1tb, I have a mid- 2010 15" MBP, so no thunderbolt. Does it matter if it's FireWire, USB 2.0 or USB 3.0? The models I have been considering are: LaCie rugged 1tb G drive 1tb LaCie Porsche P9221 *1tb My passport 1tb Freedom 1.5 tb Is there anything else I need to consider? Basically I am moving to another country and want to back up my MBP, I am also considering selling the MBP before I move. Any advice would be appreciated, Thanks Jenko.
