USB 3 port used: on the back
Working reliably, no interruptions during transfer of large GB files.
Speed between DS218 and a PC with another USB 2.5G Ethernet Adapter: about 160 MBs.

Details:

With driver 2.16.3-1 DSM7.x
r8152-rtd1296-2.16.3-1.spk
Working only with DHCP assigned IP, if a static IP is assigned in GUI then it's not operative after reboot.

With driver: 2.16.3-2 DSM7.x
r8152-rtd1296-2.16.3-2.spk
Assigned static IP in GUI correctly working after reboot.

Driver updated simply reinstalling the package, no previous package uninstall.

UPDATE 2022-11-22

I was too optimistic...:(
Unfortunately, copying large files from the PC to the NAS always works, but I discovered that if I copy large files from the NAS to the PC, after 10-20 seconds the copy fails and the NAS becomes unreacheable on the network.
The NAS resumes the connectivity if I disconnect the ethernet cable from the USB dongle and reconnect it.
But this problem occurs again and again when transeferrring large files form the NAS.
Small transfers like simply navigating from the PC in the NAS directory structure doesn't cause the problem.

Tested both with NAS static IP and DHCP assigned IP.
Tested also previous with driver 2.16.3-1 DSM7.x (only in DHCP)

Note: The same problem occurs with my other DS218play NAS.
