Tested with SAME Club3D adapter and SAME cable between two PCs, Windows 10, latest Realtek driver: 283 GB/s, Read and Write, completly stable. So the problem is the DS2415+ and/or the driver.

In the first posting, GB/s is wrong, should be MB/s of course.

Thank you for the detailed explanation.

I am now suspecting USB LPM issue, but I could not find a way to change kernel parameters in Synology environment...

So could you try to change the autosuspend settings by this command instead?

echo -1 > /sys/module/usbcore/parameters/autosuspend

How about /sys/bus/usb/devices/3-1/power/autosuspend? (3-1 is obtained by output of lsusb)
