When I worked PC support contracts at Honeywell, we would always tell people
to leave the CPU (and HD) running. Electrically, there are a lot of
transients at startup. With older supplies, it was probably a lot more of
an issue. Systems that weren't power cycled once a day were almost trouble
free even back then.
I have had systems running 98% around the clock and have very little
hardware trouble. HDs have the obvious strain of spinning up. I am not
sure how APM plays in with fatiguing a drive due to regular rotational speed
changes. These are obviously harder on a drive than running constantly.
How much power is saved would depend on how long the HD was actually
permitted to sleep. On my server, I don't think it would sleep that much.
Anyway, I choose the same route you have. Leave them up. I had
significantly greater trouble when powering up and down. Improvements in
hardware might make it a wash today. Just staying with what works.
