Interesting idea. Maybe the Transcend XS-2000 4TB needs more power than 
the Sandisk Extreme Pro 2TB.

Not sure whether I have one at hand with USB-C here, cause my regular USB 
hub only has USB-A connectors. Need to look for one with enough USB-A and 
USB-C connectors as I use an USB hub as replacement for a docking station. 
But I do have at least optionally powered hub with USB-C one at another 
place. It does not have many ports. But for the task ahead one USB-C port 
is sufficient.

I will try this as well. Thanks.

Best,
