I just got a 1tb portable external hard drive... nothing huge, but more space than anything i have. I currently use: iphoto for pictures itunes/spotify for music I have a imac (shared, roommate does time machine on his HD) and a MBA I occasionally deal with larger music files, so I'll be keeping/moving them on there. I back up using crashplan to a full external drive right now and i'm wondering how I can make everything more fluid with the larger new external. I use spotify for music on the macbook air and really only still use itunes to put music on my phone. For example, is it advisable to put my iphoto library on the external and point both computers to it? if so, would there be a way to have my air look for it connected first, then to look on the network? Basically I'm wondering how to best use all this space. Thanks!
