The Adata S102 Pro is a reasonable flash drive. Physically it has a reasonably compact form unlike its older sibling the N005 Nobility. In terms of performance the drive is around average and in terms of price it's also average. There are no obvious problems in the drive's performance profile. Overall the drive is ok but there are better bargains to be had at this time. [Aug '12 USBFlashPro]

MORE DETAILS

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]
