I would like to have all drives spin up around 22:20 or 22:25 - five minutes prior to scheduled mover to troubleshoot a problem versus just leaving drives spun up 24x7.  Is there a way to do this?  How big of a deal is it to leave drives spun up 24x7?  Assume its not a good thing from power and drive failure point of view?

Leaving drives spun up 24x7 will have an impact on power, but anecdotally it reduces the chance of disk failure as the spin up/down process is one of the more demanding processes on a drive.

Thats a myth - i use spindown since almost 10(!) years and no drive ever failed mechanicaly.

Try this - maybe it works

Put it into a file and create a cronjob.

Your sample size is WAY too small to make a declarative statement like that.

The WD-Red's have a LCC of 600.000 - my oldest disk is 4 years and 7 months old and has a LCC of 10.518 - far away from 600.000...

So spinning down the disks is absolutely not critical.
