Samsung 860 Evo & 860 Pro SSD review: the counterattack!

Samsung also refreshes complete SATA lineup of SSDs


Samsung 850 Pro vs. 860 Pro

On the outside, the Samsung 860 Pro can be recognized by the red square on the housing and inside, the differences may be just as subtle. The memory is controlled with the Pro as MLC with two bits per cell, which means less data fits on one memory chip. As a result, no tricks like TurboWrite are needed to keep the writing speed high and Samsung gives a twice as long service life for the 860 Pro.

It is noteworthy that on the 860 Pro there is only a five-year guarantee, whereas on the previous 850 Pro it was ten years. Surely this is a bit sparse for an SSD that has its supposed longer life as one of its most important selling points. However, Samsung does guarantee a lifespan of 1200 p/e-cycles, whereas the Evo is only half that.

Samsung gives slightly higher throughput rates for the 860 Pro, both compared to the Evo and to its predecessor, the 850 Pro. For sequential speeds the SSDs should achieve 560 MB/s and 530 MB/s for read and write respectively, while random performance is specified at 100,000 and 90,000 IOPS.
