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]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketing teams operate large numbers of reddit accounts. When UserBenchmark’s data contradicts their marketing spiel, they deflect by systematically attacking our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands make a large proportion lot of their profit from flagship hardware sales (4090, 14900KS, 7950X3D etc.). UserBenchmark's data helps consumers to choose hardware that offers similar real world performance at a fraction of the cost.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to make positive content about us. In addition, the brands with weaker products tend to spend more on youtube marketing, which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated reviews in an online community that's open and accessible to all. Looking at its 200+ UserBenchmark reviews, which are mostly written by virgin accounts, it is glaringly obvious that they were created by a marketing team. Real users don’t have any time or interest to promote one brand over another.
Why is UserBenchmark so popular with users?
Instead of trying to win lucrative sponsorship deals with billion dollar PC brands, we have spent the last 13 years 100% focussed on providing comprehensive, accurate and relevant information for our users. As a result, most of our users return over and over again because collectively they save millions of dollars every year.
The Best.
