But its not enough this information in Dell site, because in my Inspiron 5570 you can see 4 pin in the connector, as the picture below.
All M.2 ssd I see it's 5 pin, it's work in this notebook? Thanks.
Can you check if its read/write velocity exceeds that for SATA III ? This matter depends on socket type, ist wiring, and the bios.
Thanks in advance.
