Average Bench: 16% (300th of 639)

Based on 1,288 user benchmarks.  Device: VID 125f PID dc1a Model: ADATA USB Flash Drive

The 16GB DashDrive UV150 is a budget USB 3.0 drive from Adata. Unfortunately the performance profile is far more "budget" than the price. With sequential read/write speeds of 50/20 MBps the UV150 struggles to keep up with similarly priced USB 3.0 drives. Even Adata's own S102 Pro costs only slightly more but has nearly double the read speed. In terms of small file speeds the UV150 fares a little better with 4K read/write speeds of 10/0.3 MBps. Overall the DashDrive UV150 has a pretty bright red case, offers below average performance for a 16GB Flash Drive and is somewhat overpriced. There are far better alternatives available in today's market. [Feb '14 USBFlashPro]
