No need to check availability of NAS every 5 seconds

What I REALLY care about is that I want my NAS to put my hard drives into standby mode. (sleep).
my NAS wont put my hard drives to sleep because ROCK is checking its “availability” every 5 seconds.
With this constant accessing every 5 seconds my NAS never puts my hard drives to sleep. Hard drives have a life span and banging on them every 5 seconds is not going to help with that.
