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 new 3TB Seagate Barracuda 2016 (ST3000DM008) replaces its hugely successful predecessor, the 3TB Barracuda 7200.14 2011 (ST3000DM001). Comparing performance between the two models shows that the newer drive has 12% faster sequential speeds, comparable 4K speeds, improved mixed sequential speed and reduced mixed 4K speed. Overall, the effective speed is 12% faster on the 2016 model. Since there is normally little price difference between the two models the 2016 version is the clear winner especially for use as a backup drive with its impressive sequential read and write speeds of nearly 200 MBps. See the current value leaders here. [Feb '17 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.
