Average Bench: 106% (137th of 956)

Based on 41,035 user benchmarks.  Models: Samsung SSD 850 PRO 256GB, Samsun SSD 850 PRO 256G, Samsung SSD 850 PRO 256G, Samsung SSD 850 PRO, Samsung SSD 850

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]

Besides killer raw speed, Samsung ships Magician software with it that provides additional tuning and longevity options. Fabulous overall package.—Dec '14
