I've been using a Terramaster D6-320 (USB-C 10Gbps enclosure) with TrueNAS Scale since October and had no issues so far. I'm aware that's not a long time so can't speak for longterm results.
Before purchasing I reviewed the points raised there, and whilst they are good general points, I feel most of the potential issues listed can be mitigated for.
If you have the space to install a HBA card and connect the drives via that, I feel that is still the preferrer method.
In my case I don't have the space for that and had two unpopulated USB4 connections on my host. If you do go for a USB disk enclosure I would recommed going for a higher end one rather then a cheaper one. The one I use passes each disk through as a seperate device and has no built in raid funtionality.
