First I will have a look on how to see what USB power management options may be in place and how to tell Linux to keep the USB port the SSD is connected to at all times.
Let's see how this story unfolds. At least I am in no hurry about it.
This may not be an issue of power management but rather one of insufficient power. A laptop may not provide enough power through its USB ports for the Transcend SSD to work properly under load.
You can test this by connecting a powered UBS-3 hub between the laptop and the drive.
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,
