Examine this first:

This is an interesting article. AIUI, it's useless to spin down
the disc anyway. The graph given is an expanded scale. The very best
it shows is 9.6% increase in lifetime. To put it another way,
only 18 minutes.
Plus, if the disk spins down every 10 minutes it will exceed the
typical rating of 50,000 start/stop cycles after about 1 year of
operating time. That would be a life of about 3 years if the
machine were used 8 hours a day, so maybe it's not too bad.
