One M.2 port is for NVMe storage (PCIe), another for WiFi CNVi device.Each slot has different pin key and second (WiFi) slot is for short devices only (2230 standard)
I have a Dell micro 3060. In the BIOS there is reference to a second M.2 port: slot2_M.2 Is this physically present and if so how can it be used?Do any of the other form factors of these machines have the ability to install 2 M.2 data devices? I am assuming that this is not referring to the wifi or video connectors, but not sure.
