Put the following to /usr/local/etc/rc.d/tune-spindown.
Perhaps, we could have more clever and generalized version in base...

#!/bin/sh

# PROVIDE: tune-spindown
# REQUIRE: FILESYSTEMS
# BEFORE: DAEMON
# KEYWORD: nojail

case "$1" in
*start)
         camcontrol standby ada0 -t 300
         # dd if=/dev/ada0 of=/dev/null bs=512 count=1 >/dev/null 2>&1
         ;;
stop)
         camcontrol standby ada0 -t 0
         ;;
