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 '14USBFlashPro]
There are no read/write speeds on any of the official documentation for this drive, usually a pretty clear signal, and an accurate one in this case. I don't have this drive nor will I review it properly as the performance figures are terrible - the 4k write speeds are close to zero! This drive only just outperforms a lot of USB 2.0 drives from five years ago, I am really surprised that Kingston have released this so recently as it has no chance of competing in the now, extremely competitive USB flash drive market.
