Thank you, Alltruism. That is useful information. The one piece of information that still eludes me is whether they have a different purpose or whether they will both appear as hard drives on the computer.

I have a new desktop (from pcspecialist) with a Gigabyte B560M DS3H. I have an M2 SSD from my old computer that I was going to bring across but this motherboard has 2 M2 slots once marked M2P_CPU and the other M2A_SB. They must have different purposes but I can't find any information online...
