The DataTraveler Ultimate excels not because of its headline sequential speeds but because of its respectable and very balanced performance. Regardless of the workload you throw at it, the Kingston will perform well. Physically this drive is much larger than most and it's well constructed. From a value perspective the Kingston falls down a bit because it's one of the more expensive drives. [Jun '13 USBFlashPro]

The 16GB SanDisk Ultra Fit USB 3.0 is a remarkable flash drive. As well as packing a tiny form factor, the Ultra fit also boasts an impressive peak performance profile with maximum sequential read/writes of 129/46 MBps and 4K read/writes of 6.08/1.51 MBps. The Ultra Fit is actually only bested by three other 16GB models (Sandisk Extreme, Lexar P10, Lexar Triton) all of which cost between from 60-230% more. In terms of outright performance there are better alternatives but in terms of value for money the Ultra Fit is hard to beat. The superbly low price coupled with an amazing form factor which is barely larger than a USB socket make it easy to recommend the 16GB Ultra fit as the best small form factor flash drive on the market. The only thing to watch with the Ultra Fit are its sustained speeds which are significantly lower than peak. [Oct '14 USBFlashPro]

ALL FAQs »

 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.
