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]


USB 2.0 is old tech, so in terms of performance this drive is less than half as fast as its USB 3.0 counterparts. Interestingly the 4K write speed is reasonable at 0.4 MBps. If you plan to move a lot of data to and from the drive you will be much better off with one of the faster USB 3.0 drives. That said, the SE9 has a beautiful form factor and is both rock solid and relatively light making it ideal for use on a keyring. [Nov '12 USBFlashPro]


USB Flash Drive Rankings (Price vs Performance) March 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]
