Conclusion 
Average Bench 87%
Average Bench 85.8%

The 240GB OCZ ARC has a solid performance profile with particularly strong 4K speeds. The ARC is positioned below both OCZ's enthusiast Vector 150 and the mainstream Vertex 460 but based on hardware specs there is very little separating the drives (newer NAND on the ARC). Comparing the Vertex 460 and ARC shows that the ARC lags particularly in terms of sequential write speed but the overall difference in effective speed is marginal. The broad performance equivalence coupled with the fact that the Vertex 460 is available at the same price point makes the 240GB ARC somewhat redundant for the time being. Given that the ARC is relatively new, prices are likely to drop significantly over the coming months at which point the ARC may make more sense. [Sep '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.
