Since, I'm building my new PC, I have a big question in my mind that which SSD should I take. The 850 Pro 120GB is 90$ and 850 EVO is 65$ ( each ) ( as I like these two ) . So I wanted to get 1 of 850 PRO or 2 of 850 EVO . so, which one should I get? considering performance, durability . Cause I'm not planning to upgrade between 2-3 years after this upgrade. And also I'm getting 3 years warranty for each of these devices.
