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]

Because of its fantastic headline read/write speeds, there is often a lot of interest in this drive. It's not available in 16GB so I couldn't include it in the standardized tests. Quickly looking at the 64GB Kingston HyperX 3.0 (manuf.) claimed seq r/w speeds 225/135 @ £78 or $100. Compared to the November leader - Sandisk Extreme 64GB version (manuf.) claimed r/w 190/170 @ £45 or $79. The extreme is significantly better value, and has much much faster 4K write speeds. [Nov '12 USBFlashPro]
