What are you guys using to store your gigs upon gigs of photos? I've got a 500GB HD in my home PC, but that's where I save everything so it's running out of room pretty quick. I'm thinking about picking up a nice external HD for my photos ONLY, since I edit on a whole other PC it makes a little more sense being able to have them wherever I need them... right? Any deals going on right now? Brands I should look in to or stay away from?
