If you don't believe the maker, you can't believe anyone at this point.
When I shopped for my SSD I just got the Samsung Evo stick and was done. I didn't see it offered in different electrical layouts.
I owned a Asus ROG GL552VXK, not GL552VX. When i check on the specification list on the official website, it stated that my GL552VXK do support M.2 PCIe Gen3x4. However, some claimed that it doesn't. It stopped me from choosing to buy M.2 sata or M.2 PCIe. Anyone have idea about this?
