Hello there, I'm thinking of getting a 1 terabyte USB 3.0 external for games, music, movies etc, but, is there any performance loss when playing games this way? I was thinking of moving the whole steam app to it. Which one would you recommend? How much is the difference between 5400 and 7200? I ask because I'm not sure if the bottleneck here would be the USB or the RPM. This is for the retina 2.3/16/256 under bootcamp.
