With peak sequential read/write speeds of 140 and averages of 120 MB/s the 3TB WD Red is around 25% slower than the group leaders. If the Red is used in a NAS (Network Attached Storage), that won't make much difference because the vast majority of home networks still operate at Fast Ethernet (~10 MB/s), even users with faster Gigabit (~100 MB/s) networks will be limited by their network bandwidth before the drive. I could assume that any of our drives are for use in a NAS but that of course doesn't excuse sub-par performance because they could equally be used in a desktop. It's true that the power consumption (4.4W) on the Red is lower than average (6W) but the performance hit isn't justified. Even assuming continuous usage, those extra couple of watts for something like the Seagate Baracuda 7200.14 amount to a few pounds a year at most. At £133 this dive is both overpriced and offers sub-optimal performance. [Feb '14 HDrivePro]

This is the current version (2013) of Western Digital's best performing, Black, consumer storage drive. A comparison between the 2013 and 2010 versions shows that core real world performance has improved by around 15%. The 38 month old 2010 FAEX Black is also slightly more expensive at the moment, probably because retailers are slowly running out of stock. With average sequential read/write speeds of 150 MB/s and read/write 4k speeds of 0.8/2.9 MB/s the 2013 2TB WD Black has a solid performance profile but it's slightly overpriced. There is better value available amongst other drives in the group test[Jan '14 HDrivePro]

 Frequently Asked Questions

 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
