Question M.2 for PCI Card only or both HD as well?

[v.malev]

Hi. I have Lenovo ThinkCentre M800 SFF. I have an empty slot for M.2
I thought it is for hard drive( m.2 hard drives that are new technology and better faster newer then SSD) but on the manual (that came with my pc) it states that M.2 card slot is for installing a PCI adapter card.
So i am confused. I cannot put m2 hard drive there instead and it is only for PCI ? or is it compatible for both? I have not purchased HD yet.

I have attached a photo of the manual.

And from the illustration on pg 6 & 7, that M.2 port is only for a PCIe slot.

The M.2 form factor is not always for a storage device.
Could be for WiFi, storage, or adding a PCIe slot. Or all 3.

In this case, it seems to be just for adding a PCIe slot.

Ok thanks for confirming. I’ll stick with the regular ssd SATA HD then.
