They’re some boot issues using the adapter. I had some difficulty getting the BIOS to identify the adapter as a bootable HDD. Unfortunately I don’t remember how I solved it, but it was solvable. But you asked for potential pitfalls, so there’s one. Heat is also another issue. You don’t need to pay 200% more to get a NVMe drive with a heatsink already installed, you can just buy a normal NVMe and slap a $5 heatsink from Amazon onto it. I did that and it worked well.
