This is my first attempt at a poll so please, bear with me! I have been researching different options to consider for a new build. I'm aware that there are other makes and models but I've selected these two as a comparison. Samsung 850 PRO (512 GB) Samsung 960 EVO (500 GB) In Sweden, these two drives are priced within 5% (850 PRO the more expensive). An attempt to get an "average" of differences in performance ended with the 960 EVO as the winner by a factor of 3.2 (times higher performance). The 850 PRO has 3.3 times longer warranty (years) or 1.5 times more writes (TBW) and 1.3 times better reliability (MTBF). If you've got the time, feel free to expand on your choice!
