Can I also use this M.2 SSD in my computer?

Hello first I would like to ask what the difference between P1 and P2 SSD from Crucial are, because I would like to buy one for my computer this one: https://www.mindfactory.de/...8030.html) Mindfactory says as a form factor for notebooks now I ask myself does the SSD fit into my PC mainboard have an M.2 slot or is the size now only for notebooks so the P2 or could I also reinbuild a P1 over all?

Please do not ask the question twice.
