good flow.
The dock for 2.5" usb3 classic hard drives is recognized under ubuntu 18.04 without any problem. The speed for writing and reading large files (30 GB) on a 1 TB samsung 860 EVO SSD is 140 MB/second, which is much higher than what I had on my external hard drives, even with SSD.
Recognition under Windows 10 is not a problem either.
