Sorry if this is a duplicate, but upon searching I can't seem to find definitive answer. I have a lot of M.2 SSD cards and want to know what category they belong under. Some say as Low Grade SATA, some say Goldfinger card, I personally thought Laptop Wifi would be accurate, but I am hoping someone will give me a better answer. In the photo is both the SSD and a laptop wifi beside it for comparison. Thanks in advanced!
