The 256GB Samsung 850 Pro is the fastest consumer SSD we have seen to date. Thanks to Samsung's new 3D V-NAND the 850 Pro has lower power consumption and better performance, albeit marginally, than both the 840 Evo and 840 Pro. Looking at the benchmark figures for the 840 and 850 Pros shows that the effective performance improvement is 10% whereas the 850 Pro beats the 840 Evo by 16%. These drives effectively saturate SATA 3.0 making it difficult to distinguish between them in day-to-day use. At current prices the 850 Pro is prohibitively expensive, prices need to drop by 15% before it approaches the 840 Pro from a value perspective. Samsung may release a value orientated 850 Evo soon, but for now "most" users are better off with the 840 Pro. [Oct '14 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]
