Unfortunately I have a lot of experience with this: attaching permanent array members via USB is a bad idea. OP, if it's not too late, and assuming you haven't already and decided to double down on yolo, I'd recommend reading about the downsides of this approach. It is easy to find relevant discussions (and catastrophes) in r/zfs.
Thunderbolt enclosures are a bit more expensive, but they won't periodically fuck up your shit just because.
You are not ready to be lecturing on this topic.
