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 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]
