Greetings, My primary 850 Pro 512 is finally full and I am looking to add to my game library. I am thinking of adding another Sata III Samsung 850 Evo as additional storage, moving to 960 Pro 512 as system drive and old 850 Pro as game/ drive, or 1TB 960 Evo as a do all and moving old 850 pro to a spare PC. The 850 Evo is about $155. The 960 Pro is about $295. The 960 Evo is about $467. I am split between option 850 Evo and 960 Pro. I am pretty busy so I don't want to do much work. The 960 Pro would be a pretty simple DD op so I am not that concerned. The 960 Evo would be either a DD and repartition or maybe a backup and restore cycle. Thanks for your input.
