The Adata Dashdrive Elite S102 Pro 32GB has proven to be a popular USB 3.0 flash drive. I did a full review of the 16GB version back in August 2012 and little has changed aside from the re-branding to Dashdrive Elite. The S102 Pro still has the same robust form factor and reasonable performance profile. With Sequential read/write speeds in the region of 110/37 MBps the 32GB version bests its smaller 16GB sibling by around 30% in terms of sequential performance. This performance improvement when jumping between capacities of the same drive is common amongst flash based drives. It stems from the increased parallelization potential on larger capacity drives. Small 4K file read/write performance clocks in at 13/0.4 MB/s which is above average for a 32GB flash drive. Overall the S102 Dashdrive Elite represents reasonable value for money. [Feb '14 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]
