I have an Acasis TB401E enclosure with 2 TB Samsung 980 pro nvme and it works fine as backup drive and as boot drive with Monterey and Ventura, but not with Sonoma. Boot time is more than 3 minutes in this case. It's also worth to mention that the Acasis should be connected when the computer is off, otherwise there are issues when you change the startup disk and reboot.Acasis enclosure with 2 TB Samsung 980 pro nvme.
Flawless on M2 Ultra. 2700MB read/write speeds.
