The HGST Deskstar NAS is one of the few NAS drives to feature a 7,200 RPM rotational speed. This relatively high rotational speed helps the 4TB Deskstar NAS achieve a 4k read/write speed of 1.14/2.2 MB/s. 1.14 MB/s is actually the highest 4K read speed I have seen to date on a 4TB drive. In terms of sequential read/write speeds the Deskstar NAS clocked in at 161/144 MB/s which are also a reasonable set of scores. Overall the Deskstar NAS scored an effective speed of 116 MB/s which despite being 14% below the group leaders, is still second place for a 4TB capacity drive. With 4TB of capacity and an above average performance profile the HGST Deskstar NAS represents very good value for money. [Mar '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.
