The worst issue is, unless I am wrong you won’t have hot swap. At least when I tried the code
for the “warm swap” ritual was not in place. You can’t just unplug like you would a SAS disk. You need
to put the device in quiescent mode before.

Also, beware the NVMes and their TRIM implementation. Check firmware versions and test in advance.
I had a nasty surprise with Intel NVMEs some time ago.
