WD Smartware Excessively slow backup on PC

Following up to my post, the third party backup software finished the initial backup of my 1.2tb volume (1tb after compression) in about 12 hours.

Out of curiosity, I’m going to try to use SmartWare to back up the same volume to a USB3 drive to see if I can tell how much of the slowness is due to SmartWare and how much is do to MyCloud.
