It's so interesting to see how things keep getting more and more dense with data as time goes on. When I was in elementary school we would use 3 1/2 floppy drives to store our computer work on. The computer lab would sell them to us for a dollar a piece. Or maybe it was 50 cents, I'm not sure. At 1.44 MB, they got the job done. I don't currently have a working machine that reads those things anymore, but I do have some lying around somewhere, I'm sure.
It's just really strange to see these things out-pacing disk-based media now.
