The benchmark scores for the SanDisk Extreme were stunning. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards at the lower end of the range (10.8 MB/s - 1.71 MB/s) we observed. We suspect the inconsistency relates to the way the controller batches page cleanup. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. The SanDisk Extreme has not been released in the UK. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. We will update the price if/when the drive becomes officially available in the UK ... [Jul '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]
