I have a late 2010 MBA and am starting to run out of memory on it, with my itunes taking up the majority of my space. My question is, would it be wise/easy to get a 3.0/2.0 USB external hard drive to store some of my music and videos on? I am in college and live far away from home, so I'd prefer an external hard drive as opposed to using remote file accessing, and my school's connection is crap so that doesn't help matters. I've never had to use any sort of external storage and this is my first mac, so I'm new to all of this and any suggestion will help. Thanks.
