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]

ALL FAQs »

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
