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]

The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '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.
