Probably.  There's a tradeoff, spinning wears the disk (rather slowly;
look at the estimated lifespan for modern disks!), but starting the disk
spinning is a lot of extra wear.  So it depends how many starts vs. how
many hours of spinning.  And the exact numbers for any given drive aren't
really known and aren't available even as estimates.

Powering a system down (well, it's more the powering it *up* step) has an
even bigger impact.  Again, sitting vs. starting tradeoff, with the
numbers not known.  20 years ago it was pretty clearly better to leave a
system running for 24 hours rather than subject it to one extra power
cycle.  I'd expect that period of time to have been reduced since then,
but haven't seen recent estimates.
