I said 501GB - 1TB, but I forgot about my external.
I have 250GB, 500GB, and 37GB internal drives, and then a 500GB external. Then I have a spare 100GB and various other 20-40GB IDE drives all over the place. Oh, oh, and then I have 2x30GB drives in my webserver. And an 80GB in my other spare computer that has no use right now.
I think that's it.
