By late 99 you could catch 10GB drives on sale for $99, dude. If you were cool you bought two of them and ran them in a raid configuration so you had 20GB of space and your drives read/write was way faster. 20GB single drives themselves were still a few hundred, but that was it. I think my pc from like 1995 had 4GB drive in it to start with.

Regardless of anything else, the posted numbers are obviously wack.
