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]

The OCZ Vertex 460 replaces the Vertex 450. The main difference between the two is a change from Intel/Micron (IMFT) 20nm MLC NAND to Toshiba 19nm MLC NAND, a fitting move considering that Toshiba acquired OCZ shortly before the Vertex 460's release. Comparing the Vertex 460 and 450 shows that the two drives are broadly on a par in terms of performance. In terms of pricing the Vertex 460 is priced reasonably considering its age, I expect prices will drop rapidly as retailers build stocks of the relatively new drive. At current prices the 240GB Vertex 460 represents above average value for money but struggles to compete with its slightly more expensive sibling, the Vector 150. Comparing the 460 and 150 shows that Vector 150 leads in terms of effective speed by 10% but only costs 5% more than the 460. [Mar '14 SSDrivePro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
