Is this a 2230 M.2 Slot? - Lemmy.World

Looks like one to me. Remember that M.2 is a form factor. You can have an M.2 slot that does not support SSD storage for example. I have one that is only intended to work with wifi adapters.
Oh thanks, I didn’t know that. I thought it was an all purpose PCIe connector. Is there any way to find out whether it supports SSD storage? Is that way the dmidecode from my other comment (and basically saying that it doesn’t support storage?)

Scroll down a bit in this article. There’s a list of what each of the available keys are required to provide. A “key” in this context is basically a notch in a certain location, which then defines the meaning of the various pins of the connector. Some devices have multiple keys, as some of the specifications include each other (like key A+E is common, because E provides everything that A does, so a device that can work in A can always work in E as well. This specifically is often used for WiFi cards.

Sockets always only have one key though, for obvious reasons.
