The Supersonic Xpress has a great physical form, the innovative retractable design features a spring loaded back which snaps into place very satisfyingly, it's tempting to pop it in and out for no particular reason. In terms of performance the Xpress is below average across the board with the exception of an outstandingly high 4K read score of 14.2 MB/s. From a value perspective this drive is near the bottom of the pack, it has below average performance and is currently retailing at an above average price. [Jun '12USBFlashPro]
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.

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]
