I guess the question here is: what part of the hard-drive usually fails first
due to longevity or use over a long period of time??
As far as I know, most of the hard disk failures, I've heard of, have been
bering and drive-motor problems. If this was indeed the case then intensive
use by virtual memory drivers, which don't increase usage of these parts, would
NOT decrease the HD's life expectancy.
On the other hand if most of the failures come from the head or any other part
that will be affected by increased io then this would be a problem.
