Very true.
One year in the Iraq/Kuwait desert turned a laptop fan into a
real noise-maker -- and that was operating ONLY indoors, and
usually with a thick blanket between my legs and the bottom
of the laptop (providing some filtering mechanism) primarily
because roomies always cranked the A/C as if living in the
desert meant that indoors it should be 60F (15C)

Well of course-- the motor bearing is generally NOT the

assembly bearing often is.
It doesn't matter if you spin down the disk if you still
do the same amount of disk-head movement per day.

I can very easily imagine that modern drives will last longer
