One would think that the cause of hard drive heat is mechanical friction, but somewhere, I recently read that the main factor contributing to heat buildup in a hard drive is air friction across the platters. If that is true, I wonder why someone doesn't make a hard drive operating in a vacuum? Has anyone ever experimented with this?

Obviously, hard drive temperature directly relates to hard drive wear, the main weakness of hard drives. I would also imagine that if it did spin in a vacuum, that higher RPMS would be feasible, and offset the edge that SSDs have over them.

yeah..ah...the heads actually float on an air cushion generated by the platters.
This allows a very light 'arm' mechanism.
I don't think there's a viable replacement for the approach at this time.
