Answer to "Adding Samsung SSD 970 Pro M2 to Mac Mini 2014 with factory HHD"Actually I upgraded my mini (i5 2.6Ghz, 8gb RAM) with Samsung 970 pro myself. It was super easy: I bought an adapter for 8$ (with free shipping and tools) and installed it with this nvme added to it. In my mini, it works just perfectly, with speeds just above the 700 MB/s (that’s only because of mini bus limitations). But it’s still 2 times faster than my simple SSD which I have in the place of the old HDD. And now I have two discs in place. So I just love this solution, as it made my mac mini much more usable, at least for a few years ahead.
