The "ker-chunk" every 30 seconds is probably the syncer. There is
a patch floating around to create some sysctls to lengthen the
syncer interval. If there are no dirty vnodes, the syncer shouldn't touch
the disk, though. Personally, I'd rather have the syncer run on
schedule, then let the disk just remain quiet if there aren't any
dirty vnodes.
Every five minutes, cron launches "atrun" to see if any at(1) jobs
are pending. This triggers a write to /var/log/cron, which forces the
disk to spin up. If you don't care about at jobs, you can comment the
atrun line out of /etc/crontab.
