I have a Dell Latitude E6530 and the OEM drive, a 500GB Seagate Hybrid is pretty full, and occasionally the computer doesn't find it. Thinking it's time to pop an SSD in. I am noticing the older Samsung 850 EVO is TWICE the price of the newer 860 EVO. WTH? I understand sometimes a newer product CAN be just as good or better but cheaper due to newer technology, but wouldn't they discount the 850s to get rid of old stock? It's selling at a PREMIUM! Is there something "classic" about the 850 that make it actually better than the 860?
