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]

The 2TB Toshiba DT01ACA200 is a 3.5" desktop hard drive. This model sports a rotation speed of 7,200 RPM and is reasonably power efficient for a 2TB desktop drive consuming just 6.4 Watts when loaded and 5.2 Watts when idle. The DT01ACA200 has impressive performance with peak sequential read/write speeds of 193/182 MB/s and peak 4k read/write speeds of 1.16/2.28 MBps. These raw figures produce an effective speed of 141 MBps which ranks the 2TB DT01ACA200 amongst the top handful of 2TB hard drives. Not only is the 2TB DT01ACA200 a great performer but it is also priced aggressively and therefore represents superb value for money for a 2TB capacity drive. Comparing the 2TB and 3TB versions shows that performance is very similar but the 3TB offers 50% more capacity for just 25% more cash which makes the difference between good and great value for money. [Nov '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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
