i've been running Samsung 840 Pro 256GB drives for the last several years, they're excellent. Will be getting an 850 Pro for next build.

  He is recommending EVO. Given 840 EVO has problems with read performance deterioration for old data and the fact that Samsung doesn't even acknowledge similar problems with 840 non-EVO (I have one in an ultrabook I don't use too often and was shocked to see <10MB/s read performance on old data as well), I would be very very wary to buy any EVO in the future. We will see if Samsung actually fixed these issues in 850 EVO or they will appear as well.

    i wouldn't touch an EVO series drive for any data that mattered. EVOs use TLC NAND which is not worth giving up MLC endurance for a few $ in savings, imo.

      Hence "consumer-grade"

        their non-pro drives used to be just "830" or "840" previously and classed as "consumer grade" but still MLC. then they came out with the less durable TLC (EVO) and killed off non-pro MLC drives, re-branding the inferior EVO as the consumer drive. they also make SLC (enterprise) drives.

          840 was the first TLC quickly superseded by 840 EVO.
