I just got FCS from my teacher and I installed it. The program is much more of a beast than I expected it to be, and now I have 98 gigs left. I was wondering, can I run FCP off of an external HD? And what is the best external HD for my money? I'm hoping to buy the cheapest HD I can get with a respectable amount of memory. I doubt I will need 500gb. I am not going to be editing heavily, so I think 100-250 is the best area, but I am open to anything where I can get the best bang for my buck. Thanks a lot. EDIT: What is the best way to manage my memory? Right now the bulk of my memory taken is 50 gigs in FCS, and about 14 gigs in music.
