Samsung released Magician ver 4.6. I have a 512GB 850 PRO and still have ver 4.5. If I go to Magician Info it says I am running 4.5 and that is the latest version. So, should I bother updating to 4.6? It almost looks like it has little to do with the 850 PRO. I did change my OS Optimization to Maximum Reliability from Max Performance and it saved about 16GB, so it must have had a pagefile of my whole RAM which is 16GB.
