Very happy with the performance and stability. To echo the comments of others, many many thanks to @bb-qq for their great work :)

Note: per advice in other posted issues, you MUST use the front USB port. I had frequent stability issues that required a driver package reboot when using the back port.

TL:DR on performance Performance was largely dependent on the USB bus / adapter bandwidth, how busy the devices are, and caching. Performance was generally in the 1.2-1.4Gbps range with either my 2 x HDDs in RAID1 or older SSD drives in RAID0

The interface was very unstable on the back USB port (direct connected or via Hub so I could connect my UPS) Stability is great now that I am using the front port

Performance

Performance was largely dependent on the USB bus / adapter bandwidth, how busy the devices are, and caching. Performance was generally in the 1.2-1.4Gbps range with either my HDD or, albeit older, SSD drives in RAID0

+1. Works great on mine too. As long as you are plugged into the front USB port. When I had it plugged into the back, I'd lose the network connection every 2-3 days and had to stop and start the package to get it back. (Sabrent NT-SS5G)
