I have another that writes at the expected full speed or close enough (100+ MBps). I have tried: * Changing the enclosure from the stock to a new one * Using usb-storage "quirks" options in modprobe conf files to work around any UAS incompatibilities with the bridge (many reports of the drive working at full performance when disabling UAS, no such luck for me) * Checking the disk for errors * Updating the kernel to the most recent mainline (4.18.6 at the time) * Checking UEFI settings (I'm already on the most recent revision of the firmware) * Applying all available updates * Changing USB ports * Checking dmesg for any obvious errors (dead end, I googled everything) Again, a different external 3TB USB 3 drive does not have any write speed issues at all, so it's not the computer (Intel NUC7PJYH). However, the very same drive in both of the enclosures I have used works *perfectly* in Ubuntu 16.04 on kernel 4.15.0-34 in both a live session and installed. I am not sure what the difference is between the two LTS versions that is causing this, but unfortunately I think I've reached the end of my know-how on this. Thank you for your time, and please let me know what other information I can provide.
