needs DRAM as booting causes stutters on this one  [Dec '19 ExecutableFiles]

MORE DETAILS

Probably the best SATA III SSD you can buy for 60 US Dollar. Offered excellent performance (albeit it won't match any NVMe ones!) and suitable amount of capacity for that price. Overall a reliable all around SSD for nearly every computers unless if the computer has no support for SATA which means your computer is too old! [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.
