I have not done a full review of this drive but given its relatively rare positioning as a Rugged USB 3.0 drive, the first drive I put it head to head with, based in its official specs, was the Kingston Datatraveler R3.0. The Kingston R3.0 leads the budget end of the USB 3.0 flash drives spectrum and it also happens to be a rugged drive. The Kingston has quadruple the write speed and a 30% faster read speed than the 810. In terms of price the 810 leads but not by much. I don't think the 810 will be a terribly successful flash drive from Transcend, they need to deliver more performance, especially write, to compete in the now very competitive USB 3.0 flash drive market. [Jul '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]
