Conclusion 
Average Bench 56.8%

The WD Black (2010) is not a great performer, at least not in today's market. With peak sequential read/writes of 162/129 MB/s the Black lags particularly at writing. In terms of small file random 4K performance things are a little better with peak read/writes of 1.21/2.7 MB/s but these figures still lag the current group leaders and place the 2010 version of the WD Black well below average. A direct comparison to the 2012 WD Blue shows that the newer Blue not only outperforms on nearly every single benchmark but also costs less. [Jan '14 HDrivePro]

 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.
