Average Bench: 23.8% (166th of 634)

Based on 229 user benchmarks.  Device: VID 125f PID 312b Model: ADATA USB Flash Drive

The Adata Dashdrive Elite S102 Pro 64GB has proven to be a popular USB 3.0 flash drive. I did a full review of the 16GB version back in 2012 and little has changed since then. The S102 Pro still has the same robust form factor and reasonable performance profile. The 64GB S102 Pro has sequential read/write speeds of 105/50 MBps which is exactly in line with the indicated speeds on Adata's website. Peak small 4K file performance is currently measuring 7.84/1.49 MB/s which is well above average for a 64GB flash drive. At present our users have only submit four benchmark samples for this model, the peak 4K speeds are likely to drop as we accumulate more samples. The 64GB S102 Pro's performace is largely in line with its 32GB sibling and it bests its 16GB sibling by around 30%. Overall the 64GB S102 Pro Dashdrive Elite represents good value for money. [Feb '14 USBFlashPro]
