Works well with Windows 10
Bought this to go into my PC to link to a Synology NAS via a Unifi XG Switch. It all just works without any messing with anything. Running windows 10 latest build.

Never see anything about 6GBps
Never seem to see a consistent throughput with this. My test includes 10g nics each side with NVME drives and i7 cpus. Usually only gets to 6Gbps, occasional spike to 8Gbps.

DO NOT WASTE YOUR TIME PLEASE
What an absolute waste of time. No driver for windows 11 and absolutely rubbish. Requested return after wasting over one day of life.
