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]

We like the Kingston Datatraveler R3.0 a lot. It has an extremely well-rounded performance profile, rock solid construction, good real world performance and comes at a below average price for a USB 3.0 flash drive. Kingston have done a great job with this drive and we expect it will do well over the coming months. We could not help but notice several similarities between this drive and the Corsair Flash Voyager both in terms of construction and performance profile. Based on the success of the Voyager, that bodes well for the Kingston R3.0. In absolute terms there are faster drives to be had at this time but only if you are prepared to pay more. [Mar '13 USBFlashPro]
