@Sebastian-Roth I agree we need a system with a dual nvme drive so we can compare. I have a pdf of what all the short names really mean that I’ll link in too. I’m suspecting the field you pointed to will tell us how many and then there are other fields that will tell use more details about the drive. Also in the nvme list command I’m interested in seeing if the name space field changes if there are more drives as well as the interaction when these disks change ordinal position in respect to what udev assigns them.
