The Samsung 990 Pro has a strong consumer performance profile. It offers burst read speeds of 3 GB/s and burst write speeds of 5 GB/s. The 990 Pro also offers respectable out of cache performance. At current prices (1TB $120 USD, 2TB $165 USD and 4TB $320 USD) the Samsung 990 Pro offers worse value for money than the WD Black SN850X. Samsung’s superior SSD technology allowed them to dominate the consumer market since SSDs became mainstream in 2010. However, in today’s market, their technology no longer justifies a price premium. [Jun '24 SSDrivePro]


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.

 Frequently Asked Questions

 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
