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]

Sandisk had phenomenal success with the Sandisk Extreme which I reviewed nearly two years ago. The Extreme is still one of the best flash drives available. I had high hopes for the Ultra despite its marginally more budget orientation. Unfortunately the 16GB Ultra turned out to be a disappointment. With sequential read/write speeds of just 75/9 Mbps the Ultra lies in the bottom 25% of 16GB USB 3.0 flash drives. Small file (4K) read/write speeds clocked in at 8.35/0.08 MBps which is also in the bottom 25%. On the bright side the Ultra USB 3.0 isn't overpriced so it does represents reasonable value for money but I would happily spend a little more and get the record breaking 16GB Sandisk Extreme [Feb '14 USBFlashPro]

USB Flash Drive Rankings (Price vs Performance) April 2018 USB Rankings.

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]
