Average Bench: 23.6% (178th of 639)

Based on 1,380 user benchmarks.  Device: VID 125f PID 312b Model: ADATA USB Flash Drive

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]
