Have you wiped your nvidia drivers completely with ddu and then installed amd drivers?
I think this would take way to long to travel somewhere where things acutally live the light will probably only reach them long after humanity is gone.
I personally had the best experience with mergerfs (Drives can be any size and can be backuped by snapraid) and an external enclosure up until recently. Unfortunately USB is such a limiting factor because of bandwidth and also latency. I can only realy recommend to get a new cheap Server which has Support for sata If you want any usability while Transferring or moving files.
using less space for your storage is always better
I personally would recommend this n100 to get a real psu which can add many drives, 6 Sata ports and a standard form factor.
Edit: Also a PCIE Slot to add 10 Gbit Networking Card if dual 2.5gbit is too slow. And if you need more power there is also and i3 n305 variant of these mainboards.
I realy don’t want a cable i plug both ends in wrong and have to turn them a couple of times
