I am concerned about keeping both my USB drive and MyCloud as healthy for as long as possible. For convenience sake I am thinking about leaving my USB hard drive plugged into the MyCloud device (I generally only use it as a backup of the NAS). Is it ok to be leaving the USB plugged in all the time like this or is it not good for either device? I’m actually wondering if,overall, the connecting/disconnecting may be more damaging. Or perhaps i’m just splitting hairs! Thanks in advance for advise.
