The 64GB SanDisk Ultra Fit is the largest capacity available in the Ultra Fit range. Both the 16GB and 32GB siblings fared well in terms of peak performance but with the majority of flash based products larger capacities are faster. Unfortunately for the Ultra Fit this proved not to be the case. Comparing the performance leading Mushkin Ventura and 64GB Ultra Fit shows that the Ventura is around 600% faster but just 60% more expensive. Although the Ultra Fit is a contender in the 32GB and 16GB capacities it doesn't fare well against the 64GB competition. If you are looking for a tiny form factor the 64GB SanDisk Ultra Fit is superb but otherwise there are better alternatives available with better peak and significantly better sustained transfer speeds. [Oct '14 USBFlashPro]

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]
