How do I know which SSD(PCI-E) is right for me?

Question

Iron

I bought a used laptop, took it apart, and there is an m.2 slot, so I think I’ll put an SSD there, but I don’t know which one is suitable, I realized that PCI-E but there are a lot of them:

Here is the connector on the motherboard:

I calculated that I have 5.29 pins on the connector and those ssds that sell 5.28 and it's not clear whether they will suit me, or is there still no difference?

Answer 1

mSata or (xs what is microsata - probably the same), PSIexpresses are not like that - see what kind

Answer 2

Open the specification on your laptop and find out if you can install an ssd there. Otherwise, it may turn out that only a wifi / wwan module can be installed there.
