Hard Drive from 1975
Although this link is suggesting that this harddrive is 500KB, there seems to be a little disagreement on what the actual memory size of the drive is. Regardless, the image is fascinating and makes you realize just how fast technology can advance. Either that or Oompa-Loompas are branching out into new fields of work.
imagine the inertia of 35 pounds spinning at 3600 RPM. It had electric brakes, because if you just switched off the power, it would spin for a loooong time.
Update: If you liked this picture, you'll also like this picture of a table made from an ancient, gigantic hard-drive platter. I want one!
