The benchmark scores for the SanDisk Extreme were stunning. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards at the lower end of the range (10.8 MB/s - 1.71 MB/s) we observed. We suspect the inconsistency relates to the way the controller batches page cleanup. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. The SanDisk Extreme has not been released in the UK. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. We will update the price if/when the drive becomes officially available in the UK ... [Jul '12 USBFlashPro]

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]
