VS

Average Bench: 98% (105th of 921)

Based on 42,794 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]

i got this on sale for only a 120 bucks last year with the mounting kit. It is by far the best upgrade anyone can do

Awesome drive, own one and can say that coupled with Windows 8.1, the boot speed is virtually instantaneous—Sep '14

Comment 

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

Comment 

very impressed with speed compared to the 850 evo which was noticibly slower on my system. I sent the evo back and now all I will buy is 850 pro.—Feb '15

Comment 

Very reliable product, 10 year warranty provides a lot of relief and the rapid discounting in the channel has made this a no brainer—May '15
