I don't see this.  I do see occasional disk activity from periodic
syncs and cron activity.  How much memory do you have?  Maybe you're
constantly paging lightly.

It's probably not realistic to expect a typical unix to leave the disk
idle for extended periods of time.  I'm sure it can be improved upon
by stripping down the crontab and the number and types of daemons that
run, but unix is inherently more disk-intensive than something like
DOS or Windows.
