I have a lenovo 320S-15IKB that I bought 3 months ago with coffee lake CPU and SATA SSD,
thing is that I'm willing to replace it to an M.2 NVMe drive, so I dissembled the laptop, and have
seen it might have an NVMe slot but i'm not sure about that,

I've attached some pics.. can someone approve that it is an M.2 NVMe 2280 slot and not M.2 SATA?
If it is correct, any recommendations for NVMe drives close to 960 EVO 250GB zone?

I thought I had an answer since that sure _looks_ like an M2 setup -- socket with roughly the right overall number of pins with keyed location and threaded mounting stud. Then I started counting pins and came to a different conclusion. All of the PC M2 drives I've dealt with have 5 pins to the side of the key location while your setup seems to have 4 so I have to conclude that it is either not an M2 slot or is some freakish variant.
 




So according to the manual PM961 is test and supported by Lenovo, thing is, is this M.2 port is active? I also thought about that it has 4 pins instead of 5 on the left side,

how it is possible that there is 4 left pins?
