Is it different when you boot from an nvme drive? I have what I was told
was one and it appears as /dev/sdb or /dev/sda depending how the OS feels
that day. I didn't buy it new, it was given to me, so I may have been
misinformed. It's a thing that looks like a SIMM, and when it's plugged in
the motherboard disables one of the SATA ports, which is unfortunate.
