Average Bench: 25.5% (131st of 615)

Based on 1,611 user benchmarks.  Device: VID 0781 PID 5583 Model: SanDisk Ultra Fit

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]
