Conclusion 
Average Bench 76.9%

This is Seagate's most recent hard drive and their first 4TB consumer offering. With a rotational speed of just 5,900 RPM it's significantly slower than the 7,200 RPM Barracudas that it supersedes. The lower rotational speed results in approximately 10% slower sequential transfer speeds and longer access times which make this drive less suitable for use as a system drive. With peak 4k read/write speeds of 0.76/1.2 MB/s the 4TB HDD.15 lags the group leaders significantly. The HDD.15 is a far better candidate for use in a NAS (Network Attached Storage) where factors such as power consumption and cost per GB are more important than outright speeds. To conclude, the HDD.15 has a relatively disappointing small file 4K performance profile but it does offer a huge amount of storage at a very competitive price which makes it a good candidate for use in a NAS. [Aug '13 HDrivePro]

The 1TB Barracuda 7200.14 boasts impressive peak sequential read/write Lab speeds of 195/193 MB/s. These best case burst speeds indicate what the Barracuda is capable of under Lab perfect test conditions. Our real world benchmarks have been sourced from hundreds of users and give a better sense of how well this drive actually performs on a day to day basis. The 1TB 7200.14 has an average UBM sequential read/write speed of 147 MB/s, which is a superb result, especially for a budget drive. With 4K random read/write speeds of 0.77/1.53 MB/s small file performance is also respectable making the 1TB Barracuda a very good all round performer. In terms of value for money the relatively small 1TB drive is not as good value as its larger 3TB sibling but in the 1 TB category this is one of the best value for money drives available. [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.
