Public bug reported:
I'm trying to copy files from internal filesystems to an external
Samsung SSD T5 EVO. I'm copying a long list of large files. The first
one copies fine. The next one hangs.
If I let it run, files after the first one copy at about 3M/s, which is
extremely slow. The drive is plugged into a USB3 slot. Other drives
work fine in that slot.
Here is the drive mounting log:

This happens repeatedly. As far as I can tell, there is nothing wrong with the
drive itself. SMARTD doesn't flag anything. Samsung's Magician tool doesn't
support running a drive diagnostic on this drive.
