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 Intel 535 SSD was quietly released in April 2015, very few review samples were distributed and the release went largely unnoticed. The 535 sports the same basic specs as its predecessor, the 530. The 20nm NAND in the 530 has been replaced with marginally slower 16nm NAND and both drives use the same five year old SandForce 2281 controller. Comparing performance between 240GB 530 and 535 shows that the two drives share the same performance profile which is severely hampered by a particularly weak incompressible write speed, something the SandForce controller is notorious for. Overall the 240GB 535 scores an effective speed of 71.5% which puts it amongst the slowest handful of new SSDs on the market. There are other drives on the market that use newer technology and represent far value for money. [Aug '15 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.
