I got a new laptop and swapped my 830 into it from my old laptop and I was wondering if the 850 Evo is a good upgrade from the 830 or should I get the 850 Pro? I will be using both with a hard drive caddy anyways in the new laptop but was wondering which one should I use for the OS or if it is even worth the trouble. Alternatively is there another SSD out there that is recommended? I havent been really up to date with SSDs.
