Doubtful about this "performance"
Used the Samsung Magician on my regular Samsung SSD drives and turned on "Rapid Mode" which speeded up the SSD drives at higher speeds than the EVO 970 can handle!
Download Samsung Magician and compare yourself between a Samsung 860 EVO and 970
In addition, the M.2 disks get very hot and are expensive vs SSD.
If you drive as usual, ie without Samsung Magician, the EVO 970 will of course be faster than the 860 EVO
