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

The 16GB SanDisk Ultra Fit USB 3.0 is a remarkable flash drive. As well as packing a tiny form factor, the Ultra fit also boasts an impressive peak performance profile with maximum sequential read/writes of 129/46 MBps and 4K read/writes of 6.08/1.51 MBps. The Ultra Fit is actually only bested by three other 16GB models (Sandisk Extreme, Lexar P10, Lexar Triton) all of which cost between from 60-230% more. In terms of outright performance there are better alternatives but in terms of value for money the Ultra Fit is hard to beat. The superbly low price coupled with an amazing form factor which is barely larger than a USB socket make it easy to recommend the 16GB Ultra fit as the best small form factor flash drive on the market. The only thing to watch with the Ultra Fit are its sustained speeds which are significantly lower than peak. [Oct '14 USBFlashPro]
