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]

The 16GB DashDrive UV150 is a budget USB 3.0 drive from Adata. Unfortunately the performance profile is far more "budget" than the price. With sequential read/write speeds of 50/20 MBps the UV150 struggles to keep up with similarly priced USB 3.0 drives. Even Adata's own S102 Pro costs only slightly more but has nearly double the read speed. In terms of small file speeds the UV150 fares a little better with 4K read/write speeds of 10/0.3 MBps. Overall the DashDrive UV150 has a pretty bright red case, offers below average performance for a 16GB Flash Drive and is somewhat overpriced. There are far better alternatives available in today's market. [Feb '14 USBFlashPro]
