Average Bench: 21.1% (184th of 615)

Based on 1,260 user benchmarks.  Device: VID 0781 PID 5583 Model: SanDisk Ultra Fit

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]

As the other noted, this device is VERY SLOW. They TRICKED THE BENCHMARKS. Probably filling in some buffer in the driver instead of writing to the device, and only later dumping the data.

Testing software isn't relieable because it shows fake write speed which includes write buffer. The real write speed is ~10MB/s so it is really slow for that capacity. Even my old pendrive - Kingston Data Traveler 8GB USB2.0 has above 20MB/s write speed

Real-world write speeds are only 10-12MB/s which is very poor. The benchmarks seem incorrect.
