I'm going to need a lot of space to back things up, I'm thinking about getting 2x 500GB rather than 1x TB, that way I want lose everything if 1 packs in.
I'd use 1 for my o/s, files etc then the rest of the space as storage, and the other would be purely storeage.
The thing is, my PC is quite old (XP 1900, 1 GB Ram) and they'd need to be IDE. So I'm looking for 2x IDE 500GB HDDs.
The alternative would be to flog off my pc and build a new one, I don't need a decent graphics card so it wouldn't cost much to build a half decent spec one. That way I could buy SATA HDDs.
