I need one, my computer is a shite thing that I've crammed with some decent stuff and it's running low on Hard drive space these days. So I'm either thinking but all my crap on it, or games....I'm thinking a fairly substantial one, (in my mind) so about 600GB up for all my music, photos etc but will ALWAYS be connected. I was wondering if I could shove most of my games on there? Or will I have to put 'my shite' on the external one and then keep the games on my actual internal one.

My bro got a virus on his external hard drive. lost soo much data.

Our external hard drive no.2 has loads of games on to provide extra space.

It's not the best idea to run programs off an external HDD. If you've got a desktop, you can quite easily buy an internal HDD and install it. They're much cheaper and fairly faster.

Use external HDD for storage (Music, Videos, Pictures Etc etc)
Use internal HDD for running programs.

Done!
