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]

The Supersonic boost has an interesting performance profile. The drive put in an excellent performance in the random 4K write test where it significantly outperformed more expensive drives but it scored very poorly in the random 4K read test. So where does that leave us? Well it really depends on the intended use for the drive. The strongest aspect of this drives performance is its outright read speed which is a very respectable 85MB/s and for most flash drive users that's the figure that's going to make the most difference. [Jun '12 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.
