According to the tests shows a lower speed on my Z97M-G43. As I found out, the problem is that I have only two PCIe lines on M.2, by installing the adapter you can double the tests (it will work on PCIe2.0 4x), but for full speed you need PCIe3.0 4x, which is this mother can not be obtained in any way (if only instead of a video card). In general, as I understand it after reading articles, a growth in synthetic tests twice gives an increase in real applications of no more than 5%, so it may not make sense to twitch.
