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 Toshiba HG5d is a reasonable SSD. Considering that Toshiba is amongst the few manufacturers that produce both their own NAND flash and SSD controllers, the HG5d is a little disappointing. With a Real World Speed of 444 MBps the Q Series lies just above the 50th percentile. Relative performance is better for server orientated workloads where the HG5d scored an AS SSD Total score of 970 points putting it in 11th position and at the 66th percentile, additionally the HG5d demonstrated very strong mixed 4K transfer rates peaking at 51.1 MB/s, the second highest seen to date on a 256GB SSD. The Toshiba HG5d is not a bad SSD but neither is it cutting edge which given it's relative youth counts strongly against it. Overall there are both faster and cheaper deals to be had elsewhere. [Sep '13 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.
