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]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
