The Lexar S23 is an extremely interesting value proposition. The sequential read/write speeds of 100/30 MBps are very respectable considering the exceptionally low price point for this drive. The most interesting feature of this drive by far is its random 4k random write speed of 1.1 MB/s, this figure is actually the third highest I have ever seen on a 16GB flash drive. Overall the S23 is not a stellar performer and looses to several faster USB 3.0 Flash drives but it is, however, a superb value for money proposition, the best I have seen in 2013 by some margin. [Jun '13 USBFlashPro]

The new Adata Dashdrive UV128 has a performance profile that closely matches its older, and recently rebranded, Dashdrive Elite S102 Pro sibling. Comparing the two shows that the drives are nearly identical except for form factor. Personally I prefer a retractable form factor as USB caps are easily lost. Overall in terms of performance the Dashdrive UV128 is slightly above average and in terms of value for money it is also reasonable. [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.
