Yes, a spinning disk gathers no moss! Once a disk is running, the
heads are flying and the shaft remains centered in its bearing
by hydrostatic forces from the film of oil that circulates around
the "Oilite" (sintered bronze) bearings. There is virtually no
wear. It's the startup and shutdown that takes its toll. That's
why there are so may crashed PCs after a power failure at a
large company. The "@*(%^@_*(" disk drive(s) won't start up,
having been running fine for the past five or more years!

Cheers,
