We had high expectations for this drive, unfortunately we were slightly disappointed. On the positive side the drive has excellent sequential read speeds, but the performance profile is unbalanced and the drive is significantly weaker at writing. In terms of build quality the drive is lacking, the plastic feels loose and the drive rattles when you shake it. Overall this drive has above average performance but is also priced higher than average leaving it reasonable value for money at best, there are better deals to be had at this time. [Jun '12 USBFlashPro]

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]
