I don't understand the pricing on this drive, on the face of it, it looks seriously overpriced. Although the Black has a marginal speed advantage compared to a 3TB Barracuda, one 4TB Caviar Black costs more than two 3TB Barracudas! I have only seen benchmarks from 3 user samples for the 4TB 2012 Black so I will re-visit this recap over the coming months by which time I should have a better sample size. Additional samples may indicate far better performance than I have seen so far. [Aug '13 HDrivePro]

MORE DETAILS

This drive can be used as a combined system and storage drive thanks to its fast 7200K rpm and enormous 3TB capacity. Recently prices for all large drives have been dropping and the 3TB Barracuda 7200.14 is currently a good choice in terms of both value for money and performance. Not only does the Barracuda have respectable sequential read/write speeds but it also goes head to head with the various green options, consuming a very reasonable 5.4W vs 5W (idle) on average for a "green" drive. That amounts to a tiny power consumption disadvantage and a lot more speed. Overall the Barracuda is priced aggressively and represents very good value for money. [Oct '12 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.
