Synology DS416, 1GB Alpine4k model. Success, but speed is low. Cable Matters 2.5GB USB 3. Model Number: 202095 DSM: 7.0.1-42218 Driver version tested: 2.15.0-4 DSM7.0

Notes for functionality (it appears -5 may solve some of this, but I tested -4): Must install and let fail, run the command via SSH as instructions show, but then I had to reboot and STOP and START the service. Some testing has been done and in my case I need to stop and start the service after each reboot for the USB stick to be detected. Plus, the USB drive ONLY works in the Front USB port for me, it is not detected in either of the two rear ports no matter how many times I reboot and start / stop. Plugged into the front, it works first try.

Speed tests are only showing a max of 160MBps, running 3x IronWolf ST4000VN008-2DR166 drives in SHR. I have not tested with an SSD to see if it's the raid, or if the 1GB of ram is just slowing me down. Tests will continue.

*EDIT:

Updated to 2.15.0-5 DSM7.0 No longer have to stop/start after reboot. USB is detected properly as part of the startup sequence! Still must be plugged into front USB, Rear no detect.

Speeds are indeed an issue. Installed a Samsung Pro SSD, write speed average 190-200MBps with 225MBps peak, read speed 120MBps constant. It almost feels as if something is limited my read speed to 120, as there is little fluctuation. My 1gb connection can read at 109, so this is higher, but not by much. The write speeds are appreciated though.

Increase MTU to 9000 and set SMB protocol version to v3 may help to improve performance.

Thank you for posting. This increased my read speed from 120MB up to 165-170 in windows, and up to 195 from linux. A good improvement. Still not the full potential, but I am dealing with old hardware on 1gb ram, so it's a nice boost.
