I have poked around and watched some videos on M.2 and seems I can't really expect any noticeable performance boost. But I would like to at least use the slot to get some experience with it my self.
I got a MSI X370 GAMING PLUS AM4 AMD board
Newegg shows "KEY M" as the socket type but when I look at the hard drives they seem to go by numbers for the socket types.
But on the other hand none of the forums or videos I have watched mention anything about socket types... so not sure if there is any variations at all in the first place.
Any other pointers/information is welcomed also.. things have changed a lot since I went to tech school but I still like to at least try to keep up.
