[citation][nom]idroid[/nom]who actually uses that much storage?[/citation]
well... lets first go with porn
than lets also go high res raw photo storage
lets also add in uncompressed files (textures and such, for useing in photos)
lets also go in with rip and encode all the movies i own, so thats 700mb to 2gb a movie right there, and a large collection... that can be high up there
games and making backup copies of all your games, in case they ever break
and lets lastly go into just video production, whether you capture from a webcam/games/or full low/uncompressed hd, that crap takes up a crap ton of space no matter what.
and all that is without going into illegal things you can do with it. which i believe you were alluding to.
