Currently one of the highest capacity consumer SATA SSD on the market, this SSD offers huge amount of capacity and high R/W which is limited by SATA 3 max bandwidth. However, 4TB SSD and bigger begin to offer lower GB per dollar (which equals lower value) than the lower capacity SSD in the market such as 2TB NVMe SSD (Intel 660p 2TB at $194-209). [Dec '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.
