Quiet and efficient: very satisfied
This enclosure is well finished, it's quick and easy to install and deploy. The performance is excellent, with a SATA slot and an M2 slot for disks.
I'm running an ESXi with lots of VMs in it, it never falters and is completely silent!
Exactly what I wanted. My only complaint is that the M2 slot is quite large, I would have liked to see dual SATA / M2 connectivity.
I don't use the M2 slot at the moment, as M2 drives are more expensive and offer less storage, and above all they heat up a lot more, something I wanted to avoid as the machine will be running 24/7 on passive cooling.
