so my mobo is the 4 years old asrock z97x killer and it was among the first to feature an M Key M.2 slot
it's very primitive, running at pcie2.0 2x (10gbps theoretical) through the chipset but apparently supports a few newer 3.0 x4 drives...
this is the official tested drive list: https://www.asrock.com/mb/Intel/Fatal1ty Z97X Killer/#Storage
noteworthy is the fact that the board had multiple bios revisions that stated "improved nvme compatibility"
my question then is could this support super modern nvme drives such as the 960/970 series by samsung?
