As ive said before, i went on a lot of research, & i mean constant 10-20 videos & web browsing, the best pc parts, what goes well into what, budget part..yada yada.. so i with that in mind, for the price it was on, Samsung 850 evo was a no brainer , it looks sleeks (black with a satin feel) & a superb read & write speed.
I wanted SSDs for my operating system and my favorite video games, but then I couldn't decide on which games I wanted to put on the SSD and which ones wouldn't get the special treatment. So I got one SSD for the OS and one for the games. Problem solved. Unless you like spending money I don't think there is any reason to go with anything else besides the 850 EVO. Almost nothing else performs as well (not even the 850 pro) and anything that does has a dumb price tag. So 850 EVOs for me. The 120GB for the OS and 250GB for games, in case you were wondering.
This SSD is very helpful! I'm using it to store all my important content that I want to load faster to be more efficient! It's working great so far and I really recommend it to you!
