I appreciate the data point.  Even though my Shield TV has usb3 ports and
my usb memory key was usb3, I think that internal storage has to be faster.
I'm only using USB external storage for transfers from now on.

I've had no issues since removing that USB stick.  I did lose one app, but
quickly reinstalled it.
