I shouldn't get into this, not being a MacBook user , but your screed above only mentions Macrium when experiencing overheating... no mention of Hasleo doing the same (I assume it does).  If you haven't tried it, you should.  Both v8.x of Macrium AND Hasleo make extensive use of multi-core/thread operations so they will, indeed, run your external devices at their maximum capability if you're making all your cores/threads available to the Parallels virtual machine... possibly causing this condition you're seeing.  You can always shrink (less cores/threads) the size of your virtual machine to see if that may help.

I don't know about Parallels but VMware does allow you to configure "virtual" USB ports as either USB3 or USB2.  Since USB2 by design is slower in its protocol use, if that's possible with Parallels I would try it.  Your FULL image will be slower but your Incrementals should be decent.

The end result, though, should be the use of a UFD that doesn't overheat or die when used at its maximum speed allowed... remember, the device itself controls how fast it may be used, not the laptop and its device controller.

I'm not sure what else I could suggest... will give some more thought to it, though... good luck!
