The Adata Dashdrive Elite S102 Pro 64GB has proven to be a popular USB 3.0 flash drive. I did a full review of the 16GB version back in 2012 and little has changed since then. The S102 Pro still has the same robust form factor and reasonable performance profile. The 64GB S102 Pro has sequential read/write speeds of 105/50 MBps which is exactly in line with the indicated speeds on Adata's website. Peak small 4K file performance is currently measuring 7.84/1.49 MB/s which is well above average for a 64GB flash drive. At present our users have only submit four benchmark samples for this model, the peak 4K speeds are likely to drop as we accumulate more samples. The 64GB S102 Pro's performace is largely in line with its 32GB sibling and it bests its 16GB sibling by around 30%. Overall the 64GB S102 Pro Dashdrive Elite represents good value for money. [Feb '14 USBFlashPro]

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]
