The 3TB Hitachi Deskstar 7K3000 once delivered performance that rivaled the long established class leaders in this capacity (WD Black included) and at an extremely competitive price. The drive was special in that it had 5 platters (vs the usual 3) and ran at 7K rpm despite having a relatively high capacity. The new design worked fantastically well resulting in a class leading product at launch. That was nearly three years ago. With peak sequential speeds of 95 MB/s and 4K speeds of 1 MB/s the Deskstar 7K3000 can no longer compete and clocks in around 35% slower than its modern day competitors. There are far better deals to be had elsewhere at this time. [Oct '12 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.
