Average Bench: 19.9% (211th of 639)

Based on 338 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 1.1 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. Overall the 32GB s23 offers above average value for money and decent, especially small file, performance. [Jul '13 USBFlashPro]

Cute drive, but my daughter started using this for a big project at school. After hours of work and saving it diligently to the drive (going between different computers at class and home, so no other way), it starts disappearing off her desktop on the third day of use and shortly will not load at all. Tried it on different computers and it doesn't work at all. Hours of work down the tube. I've used a lot of flash drives and never had one give out. Watch out. Contacted Lexar and they didn't offer any help other than warranty exchange. Doesn't Lexar do any quality control any more?—Sep '14
