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]

The 120GB M500 is successor to the phenomenally successful Crucial M4. The M500 was poised to win loyal M4 customers but as it turns out the new M500 is worse for typical consumer use than the now nearly three years old M4. There are some cosmetic performance improvements over the M4 but they are purely synthetic. For example, deep queue speeds are significantly improved and the newer M500 handles mixed IO far better. Consumers require decent sequential read/write speeds which average 435/185 MB/s on the M4 vs 395/134 MB/s on the M500! Other manufacturers have come leaps and bounds over the last three years which has raised the performance bar is several notches. In today's market the new M500 simply cannot compete on performance, it doesn't even come close to the likes of the Samsung Evo or OCZ Vector 150. The M500, however, is one of the cheapest mainstream SSDs available at this time but it's easy to justify spending just a little more for a lot more performance. [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.
