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,
