Currently one of the highest capacity HDD or storage devices to appear in UserBenchmark. Performance is slightly slower than much more popular and mainstream Seagate Barracuda 1TB/2TB and WD Blue 1TB. Can potentially store thousand (if not tens of thousand and more) games (not even recent triple-A ones which bogs up large amount of storage!) but transferring all of them requires waiting for couple hours to few days. [Nov '19 ColdSpy]

 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.
