Samsung T5 Slow on all USB Ports on Desktop

Jan 25, 2019
Hey Friends,

I have a couple Samsung T5's I've been using for a while. I usually get 300-450 MB/s transfer. In the last couple days my desktop decided that they can only transfer at 41-42 MB/s. I've tried in USB 3.0 and 3.1 Gen 2 (both USB A and C) and it is always the same. I have a laptop as well, and it seems to run fine. I've removed the USB Controllers and let Windows reinstall them. Updated everything I can think of and uninstalled everything from the last few days to no avail. I used a Lexar flash drive and it copied at 150MB/s off the USB A 3.0 and 3.1 ports. I don't know where else to check.

Any ideas?
