The 860 Evo is the latest mainstream SATA SSD from Samsung. The 2.5-inch version of the 860 Evo will be available in several capacities ranging from 250 GB to a staggering 4TB. It’s also available in the slimmer M.2 and mSATA form factors. The 860 Evo demonstrates marginally reduced performance compared to its popular, but now three year old predecessor, the 850 Evo. In a head to head comparison the 860 looses by a very modest 6% in terms of effective speed. The 860 Evo is based on a refinement of Samsung’s consumer grade TLC V-NAND, this time featuring 256Gb and 512 Gb 64 layer V-NAND and it also features a new "MJX" controller. The 250 GB version can reach sequential write speeds of up to 520 MB/s, dropping to 300 MB/s once the SLC cache is exhausted (the 250 GB version has a 12 GB SLC write cache). Peak sequential read speeds of 560 MB/s are achievable across the different capacities. The 250GB version has a 512 MB LPDDR4 DRAM cache. All capacities have a five year warranty, but as a testament to the enhanced reliability of this new technology, the warrantied terabytes written (TBW) has doubled from 75 TBW to 150 TBW for the 250 GB 860 Evo. [Jan '18 SSDrivePro]
