by default, the fans always spin and the disks always spin. Sure, in an office setting or even closed up somewhere, this would not bother me. But ours is in a room next to the bedroom, so at night I could hear it whirring away.

And the disks spin down after 5 minutes of non use (at which point it turns off the light ring on the front).

When you implement those to things, the device is completely silent most of the time, and I would assume using less power as well.

The best starting place is here:
