Samsung MZ-7KE256BW

850 Pro 256GB

▲ 5441,218 ▼

Controller: Samsung Triple Core MEX. Memory: Samsung 40nm MLC V-NAND. Release date: Q3 2014.

Average Bench: 102% (237th of 1058)

Based on 137,752 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]

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

For a 2014 released and bought SSD drive this still kicks ass in 2020. Its light weight, easy to mount, plug n play, ofcourse its SATA but above all, its still fast to this date!
