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 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]
