The WD Black SN850X has a superb consumer performance profile. As well as offering solid burst speeds of 5 GB/s, the SN850X also offers respectable out of cache performance. At current prices (1TB $90 USD, 2TB $145 USD and 4TB $290 USD) the WD Black SN850X is our top value pick at every capacity. [Jun '24 SSDrivePro]

MORE DETAILS

The Intel 520 Series was Intel's first SSD to feature a Sandforce 2281 controller. This controller has powered countless SSDs over the last three years but is now dated and is known to be limited in the area of incompressible write speed. The 120GB Intel 520 scored peak and average sequential read/write speeds of 514/157 and 421/133. These read speeds are good but the peak write of 157 MB/s lags the group leaders average of 313 MB/s by nearly 100%. This relative inability to write lowers the 520's overall effective speed to 403 MB/s or 15% lower than the 459 MB/s achieved by the group leaders. At two years of age the Intel 520 can no longer compete with newer drives, there is far better value available amongst the group leaders. [Feb '14 SSDrivePro]

 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.
