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.

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]
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]
