Average Bench: 20.7% (193rd of 622)

Based on 144 user benchmarks.  Device: VID 05dc PID a833 Model: Lexar USB Flash Drive

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]

Use it on my Sony TV for recording, works perfectly, very cheap build though, don't think it would last long if actually using as a portable drive
