Vibration on 4GB MyCloud

How much vibration is it normal to feel on this device before it becomes a concern?  I cannot hear much, but I can feel a little.

P.S.  Do something about that hurried how-to video on the get started page.  What was he on?

         Also fix the lame user community account creation page… so many gotchas there.

This NAS is beautifully silent in normal operation and should vibrate as much. Completely silent in my experience, compared with a Synology drive that hums (because of fans) and of which enclosure vibrates noisily easily.
