The 16GB version of the Lexar s23 has superb potential thanks to its decent read/write speeds of 100/30 MBps, an outstanding 4k random write speed of 0.6 MBps and its superb price. At the 32GB and 64GB capacities the s23 is no longer as attractive because its speeds remain mostly unchanged from those of its younger 16GB sibling. Generally speaking larger capacity drives have better write performance which makes the 32 and 64 GB segments faster and therefore significantly harder to compete in for drives that don't utilize the additional panellization opportunity. [Jul '13 USBFlashPro]

ALL FAQs »

 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.
