The 860 Pro is Samsung’s latest consumer-grade SATA SSD flagship, superseding the popular, but now three years old, 850 Pro. Like the 850 Pro, the 860 Pro is based on Samsung’s proprietary and revolutionary (at the time), MLC V-NAND (3D). A 10% price premium over the 256 GB 850 Pro will purchase the 256 GB 860 Pro which has an impressive 16% faster effective speed. This is achieved via an updated controller (MJX) and 64 layers of V-NAND (versus 32 layers per the 850 Pro). The 860 Pro has sequential speeds of up to 540 MB/s which almost completely saturate its SATA 3.0 interface. These peak levels of performance are slightly higher, but still comparable to the peak performance of the 860 Evo before its SLC write cache (12 GB on the 250 GB Evo) is saturated, making the 860 Evo (at around 30% cheaper) a more economical choice for users who rarely write more than 12 GB at a time. There are also reliability improvements compared to the 850 generation with Samsung now offering a warranty of 300 TBW (terabytes written) for the 256 GB 860 Pro, compared to 150 TBW for the 256 GB 850 Pro. Thanks to higher density NAND, the 860 Pro is also available in a 4 TB variant, whereas previously 2 TB was the largest capacity for a Samsung SATA MLC SSD.  [Feb '18 SSDrivePro]

MORE DETAILS

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]
