Create an /etc/rc.local (if you don't have one already) and put this in
it:

  camcontrol idle ada0 -t 0

Put one of those lines for each drive.  -t 0 disables spindown.  Instead
of zero you can put the number of seconds of idle time you want before
the drive spins down.

To manually spin down a drive immediately:

  camcontrol standby ada0
