The 128GB Samsung 830 is nearly two and a half years old which puts it at a significant disadvantage to more recent models. With peak and average sequential read/write speeds of 512/323 and 410/239 MB/s it's not too shabby, especially considering its age. The sequential figures actually match the current group leaders. The small file 4K peak and average read/write speeds of 22.5/60.3 and 17/40 MB/s are not as impressive and lag the group leaders by 50%. Reduced small file performance weighs on the 128GB 830's effective speed which is 376 MB/s and 20% lower than the average of 453 MB/s for the highest voted group leaders. Finally comparing the 128 and 256GB versions shows that the larger drive has a superior performance profile, which is not uncommon for SSDs but newer models from Samsung don't share this trait. [Feb '14 SSDrivePro]

The OCZ Vertex 460A is basically a tweaked re-release of last years Vertex 460. The two drives share the same controller and the same basic NAND, although the 460A apparently uses a newer version of Toshiba's 19nm MLC. Unsurprisingly there is little difference in performance between the 460 and 460A. In absolute terms, with peak sequential read/write speeds of 516/500 MBps and peak 4K random read/write speeds of 25/120 MB/s the 460A does have a rock solid performance profile but OCZ cannot afford to re-release 12 month old technology, at least not of they want to continue to compete with the likes of Samsung, SanDisk and Crucial who are continuously innovating. Overall the 240GB 460A still sits amongst the top handful of drives both in terms of outright performance and value for money. [Jan '15 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
