The 32GB Sandisk Ultra Fit has both a tiny form factor and a respectable performance profile. With peak sequential read/write speeds of 136/55 MBps and peak 4K read/writes of 6.6/2.0 MBps the 32GB Ultra Fit sits amongst the top 25% of 32GB flash drives. In terms of value for money the Ultra fit fares even better and is bested only by the Sandisk Extreme. Comparing the 32GB Extreme and Ultra Fit shows that the Extreme has over double the effective speed yet the extreme is only 32% more expensive than the Ultra Fit. To conclude, the 32GB Ultra Fit has good peak performance (sustained performance is far less impressive) but its key strengths are its tiny form factor and reasonable price tag. [Oct '14 USBFlashPro]

The new Adata Dashdrive UV128 has a performance profile that closely matches its older, and recently rebranded, Dashdrive Elite S102 Pro sibling. Comparing the two shows that the drives are nearly identical except for form factor. Personally I prefer a retractable form factor as USB caps are easily lost. Overall in terms of performance the Dashdrive UV128 is slightly above average and in terms of value for money it is also reasonable. [Jul '13 USBFlashPro]
