I want to know if 3620rpm on the first one is the rotation speed of the outer cylinder or the inner cylinder or an avergae or something. Because if it's the outer cylinder, that's one slow hard drive.

Nice find man... that's amazing. Look how far we've come in 20 odd years. Could you imagine trying to install one of them babies in your PC? Hehehe, you would need a crane. And back then they probably would never have imagined having the hard drive capacity we have these days in such a small size.

Are you sure these aren't motorcycle engines? *grins* Seriously, I wonder how many MP3s I could get on one of those ... and my next question after that would be, "How badly would I hurt myself when I had to move that thing out of my apartment at the end of the semester?" Heh.
