Is a 500GB external hard drive enough for a film student? Im starting University soon to study Film production, just wanted to know your opinions if 500gb is big enough? I have a Canon 550d t2i and plan on storing all my footage for my current films and future films on my hard drive. Apart from that I plan on having some music and photos on the harddrive too, but its the videos that will take up most space. What do u guys think?
