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]

Having just done a review of the 16GB Sandisk Ultra which wasn't a great performer but still managed to represent reasonable value for money, I was expecting much the same from the 32GB Ultra. Generally speaking moving from the 16 to 32 GB capacity results in a doubling of the write speed. This was not the case for 32GB Ultra which had a performance profile that was almost identical to its 16GB sibling. As a consequence the 32GB Ultra is amongst the bottom 5% of 32GB Flash Drives in terms of performance and only slightly better in terms of value for money. There is no doubt that it's worth spending a little more on the superb 32GB Sandisk Extreme[Feb '14 USBFlashPro]
