i have a small music library (8 GB) and a big video library (260 GB)...and this is all stored on a 300 GB external hard drive (i have set it up so if i put something in iTunes it goes straight to the external HD).....i am eventually going to have to get another external HD because my library will just get bigger but.....i don't like the fact that all my content is on this external HD and if this somehow crashes and dies i loose everything and i know i would probably cry if this happened (not joking).....so i would like to buy another external HD to be able to back-up my current amount and also be able to hold another 100 GB or so.....what do you guys reckon??? what would be the best set-up??? i was thinking something like a 1 TB HD and back-up my current 300 GB external onto it and then set it so new iTunes stuff goes onto that now.......any suggestions would be great....
