I've a Synology NAS with 2 WD Red hard drives. I've enabled the hibernation for the drives, so they stop after 20 minutes inactivity.
However, we use the NAS a lot and the disks get powered up very frequently. I was wondering if hibernation could cause earlier failure of the drives in the situation, and if I should disable it. I understand hibernation saves energy, but I care about the integrity of my data more.
Thank you!

I think hibernation would be more risky than just leaving the disk spinning simply because you are exercising the motor more. Steady state should be more reliable. However I can't find any studies supporting the theory.

The documentation says they are good for 600k load cycles with a 3 year warranty.
600k/(365*3) ~= 548
That is ~540 stop/start cycles per day. That sounds ok for me for normal power cycling as described.
