yes…
I think the best choice of Hitachi as it comes with the original Mac, but I am not an expert in this practice, so I want to hear other views
well i looked extensively for a 1tb 2.5", and they are hard to come by.
you could go for a 750GB... however i recommend the seagate momentus 500gb. good size and its a 7200rpm speed, so you'll get aslight performance boost.
