what is a good hdd to run wii games off of. i have about 70 games i want to put on the hdd but i dont want one that has to be constantly plugged into the wall. the games range in size though. theyre from like wii sports to black ops to super smash bros brawl. would a 500gb one suffice. also where does the save data memory from the games save to. there is no way that the wii itself could hold all that save data. does that also save to the hdd. thanks.
