Well.I Just recently bought Samsung 850 EVO + New Windows installation disc. After many tries to install on it, I failed. Felt like it is just not accepting the installation, by complainig that there can't be found a necessary drivers to continue.. wth just unboxed original WIN 7 64 HP. OK, maybe installation problems. Then i decided to clone my HDD to it. Yay it worked fine, took some time to clone nearly 400GB, but it was running ( was happy that ssd is not broken and actually I can get a windows on it) , but trying to play the games (actually thats why i bought it), my happiness blurred away. Had couple of games cloned with the Windows from my HDD, such as battlefield 4, CS:GO, ESO. All of them was glitching like hell and showed 5x times less FPS. Like for example, CS.go where i usually had 200 FPS, now i have 20-50 + it freezes like every two miliseconds and the same happened/was infeced with the source HDD and to games on it. I used Original Samsung software - Data Migration and Data Magican. Can someone help, please ?
