Sandisk had phenomenal success with the Sandisk Extreme which I reviewed nearly two years ago. The Extreme is still one of the best flash drives available. I had high hopes for the Ultra despite its marginally more budget orientation. Unfortunately the 16GB Ultra turned out to be a disappointment. With sequential read/write speeds of just 75/9 Mbps the Ultra lies in the bottom 25% of 16GB USB 3.0 flash drives. Small file (4K) read/write speeds clocked in at 8.35/0.08 MBps which is also in the bottom 25%. On the bright side the Ultra USB 3.0 isn't overpriced so it does represents reasonable value for money but I would happily spend a little more and get the record breaking 16GB Sandisk Extreme[Feb '14USBFlashPro]
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.

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]
