Both the cable and the port on the PC has to support USB 3.X speed.
I connected my external USB 3.x cabinet to my laptop USB 3.x port yesterday with my mobile phone's USB charging cable. That did not go well, the cable only supported USB 2.0 speed, 480 Mbit/s = 60 MB/s (theoretical). When I switced to a USB 3.x cable I got 10 Gbit/s = 1250 MB/s (theoretical).

Maybe because of a bad/loose USB cable or worn port.
- try a different USB 3.0 cable
- try another USB 3.0 port (rear if desktop)
