Average Bench: 111% (151st of 992)

Based on 1,789 user benchmarks.  Models: Samsung SSD 860 PRO 256GB, Samsung SSD 860 PRO 256G

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]

2012 i bought hyperx 120 gb and only 1 gb free space left. it was full with application then looked results and tough 860 pro better then kingston. kingston hyber x 120 gb read speed 555 Mb (2012 model) and 860 pro (2019 model) 560 mb read speed honestly i replaced only ssd drive and kingston definetly faster then samsung even it has 1 gb free space, when i click applications it load faster then samsung.. windows starts, opening firefox, photoshop or intellij vs 7 years old kingston ssd definetly faster then samsung 860 pro ssd disc.
