Conclusion 
Average Bench 443%

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 Evo, like its 250GB sibling, features a second level Turbowrite cache (TWC). This 3GB block of high speed SLC memory allows the Evo to write data at 370 MB/s, nearly double its normal rate. When the TWC is full write speeds drop by around 50% but since consumers generally write less than 3GB in a typical write operation, the performance drop will rarely be noticed. On the other hand, in a server environment this sort of performance degradation would be unacceptable. Comparing the 120GB and 250GB Evos shows that they have similar performance profiles. The performance equivalence between the different capacities, coupled with the fact that their prices are almost linear, implies that both capacities represent roughly the same value for money. Within its TWC, the 120GB Evo is capable of chart topping burst IO rates and it sits squarely amongst the best performing 120GB drives. [Aug '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.
