yeah buy high speed hdd, case with enough spec and use as portable. I got cheaply 2.5 seagate 500 7.2 (they are crap but price is low..), and bought 2.5 logilink alium case... Works like a charm and saved myself $50 Also it is good that you can change then every time with laptop hdd.... Seagate warranty 6 years... case 2 years ( but they never fail).....
