Take my advice however and don't get the biggest internal HD you can find. They die in a couple of years anyways. You'd be better off to get a 250gb internal HD and a 1,000gb external than a 500gb internal and a 750gb external. Let's say you have $250 to spend and you see an external 1,000gb hard drive for $219. Go ahead and get it and then go a little over budget and get a 250gb internal drive for $59. If you want you can go get a disk image program and just totally copy your current HD to your new one. It would save you the trouble of setting up a master and slave drive and ya gotta admit that 80gb is pretty useless by itself. Just believe me when I tell you this. No matter how large of a HD you get, it will never be enough. I remember when I spent a whole $350 on a 80gb hard drive 9 years ago and I thought I would have all the storage I'd ever need. Now 80gb is practically a flash drive.

: I mean, if you're going to spend $149 on a 500gb HD, you might as well get the 1,000gb for $50 more. Trust me, you'll need it.
Computers are money money money and when it comes to buying computer stuff, you'd be MUCH better off to spend a little bit more and get twice the performance or storage.
Want more specific buying instructions? Get this external HD. It's a little over priced, but it's a much better quality drive:

Speaking of hard drives, take a look at this sucker. They can't get hard drives past 1.5tb so they put two 1tb drives into one huge and ugly package.

It's about as big as the freaking computer itself!

Even their studio pic makes this thing look like a piece of garbage. I can't imagine having that sucker on my desk.
