I have several very cheap big-ish external harddrives as well as a big high quality backupdrive. All of them are 3,5'' and have their own power supply and I havent lost any of them yet. The one I use for my WiiU is one of the cheap ones and it works well.
I have made very bad experiences with 2,5'' ones however. they always grow too powerhungry, even with a y-cable or die of mechanical failure.
