There are two SSD series which sold extremely well during the last year: the Samsung 840 Evo series and the Crucial MX100 series. Perhaps the most important factor was the extremely competitive prices of both series. Although other manufacturers are certainly trying their best, the battle for the favour of the SSD-purchasing consumer appears to become more and more about Samsung and Crucial. Recently, the 850 Evo series was introduced as the successor to Samsung's 840 Evo SSDs. These new Evo drives should be faster and (even) more reliable than their predecessors. Will Samsung be able to break Crucial's stride? We have extensively tested the complete 850 Evo series ? that is, the 120 GB, 250 GB, 500 GB, and 1 TB models ? in order to be able to answer that question.
