I have a Samsung 960 Pro M.2 drive and after several months it is still not recognised as an SSD drive. It is not a new drive any longer and is a well-recognised brand name.
What is going on at Piriform that they can ignore an issue that many have complained about and with other M.2 drives as well, Speccy can recognise as a SSD, they send screenshots and still Piriform fail to rectify it - do they not read these columns ? If so, what's the point in posting here ?
