So I just got my external and I have it set up and looking all nice an pretty... but that is all it is doing. I have never used one before and so I am a little unsure of how to put my stuff onto it. I would like to put all my music and iTunes and all my games onto it so it can clear up my laptop hard drive a bit. I want to be able to run them from the external too (I don't want to use it just as a back up drive) you know what I mean? Will things still run as fast if I run them from the external as opposed to my internal? Thanks!
