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]

MORE DETAILS

The 2TB version of WD's Red NAS range of hard drives has a performance profile that is similar to that of its larger 3TB sibling. Both drives lag behind the group average significantly in terms of overall performance. With an average read speed of 108 MB/s the 2TB Red is 36% slower than the group leaders which manage an average of 147 MB/s. There is a huge amount of hype around the "NAS" aspects of these drives but there is very little substance in terms of specific characteristics that make this drive better suited to a NAS than any other. The obvious factors such as energy efficiency and operating temperature are only marginally improved on these drives. I would personally prefer one of the far better performing Seagate Barracudas as when looking at a direct comparison of the Barracuda vs the Red it's clear that the performance of the Barracuda is better across the board. [Feb '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.
