The new 4TB WD Red Pro is an upgraded version of WD's popular Red NAS (Network Attached Storage). The Pro Reds have a rotation speed of 7200 RPM unlike their regular Red counterparts which are marketed as "IntelliPower" but actually spin at fixed speeds of 5400 or 5700 RPM depending on the exact model. Comparing the regular 3TB Red and the 4TB Pro shows that the pro version is significantly faster across the board. The biggest performance gains are seen in the small file 4K area and are a direct consequence of lower access times due to the higher rotation speed of the Pro Red. As well as offering better performance the Pro Reds have 5 year warranties vs 3 years on the regular Reds. Unfortunately it's not all good news as the Pro Red is priced around 50% higher than its regular Red sibling and thus currently represents average value for money at best. [Oct '14 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.
