Is it possible to replace the drive inside of the enclosure or is it proprietary? I wonder if it’s just an M.2 adapter to USB.

The cards are pretty small so I doubt there's enough space for an m.2. I would guess proprietary

Yeah they’re not quite long enough as it turns out, although a different module could stick out if you really wanted it to.

It is indeed proprietary, but I think they share the design resources for it.
