The 6TB WD Red is one of the first 6TB consumer drives. Sporting five large 1.2TB platters the Red is targeted at consumers for use in 1-8 bay NAS (Network Attached Storage) devices. The large platters on the 6TB drive enable slightly faster peak read speeds than on the smaller capacity Reds. Comparing performance between the 2TB and 6TB versions shows that the 6TB version is between 10 and 15% faster. At current market prices ($300) the 6TB red isn't a bad value proposition and, considering that the 6TB Red is just a few months old, prices are likely to drop significantly over the coming months. [Oct '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.
