It tells you in the manual for the board. Some do both and others are either one or the other.So I see there's the M.2 form factor but there's also PCI 3.0 and PCI 4.0 SSDs. When looking at the motherboards, does it state whether the M.2 is PCI 3 or 4?

Alright cool. I just wanted to be sure these were still using the M.2 slots and not the PCIe slots.

First one is connected to the CPU. With a Ryzen 5000 series CPU, it offers PCIe 4.0 speed but with 5000G series and 4000 series, it can only run at PCIe 3.0 speed.
2nd M.2 connector will always run at PCIe 3.0 as that's the best this particular chipset can muster.
If you go with Alder Lake/Raptor Lake/Zen 4, the presence of at least one PCIe 4.0 M.2 slot is almost guaranteed, unless the mobo is a really crappy cheap model.
Is there something wrong with the information I posted? Trying to figure why it got downvoted.M.2 are typically SATA or PCIe (but I also believe they can be USB). PCIe drives only have a single notch on the edge connector. PCI 3 vs 4 (and now 5 with Zen 4 on AMD) not only is it motherboard dependent but also CPU dependent so you need to check both.
I meant PCIe.In general, no, they run off PCIe. I haven't seen PCI been used for some time.
