Average Bench: 16.1% (293rd of 639)

Based on 464 user benchmarks.  Device: VID 125f PID dc1a Model: ADATA USB Flash Drive

The 32GB DashDrive UV150 has an average performance profile for a 32GB USB 3.0 flash drive. With sequential read/write speeds of 108/34 MBps the DashDrive favours reading over writing and lands somewhere near the middle of the pack for overall sequential performance. Small file performance is much better with peak 4k read/write speeds of 7.4/1.15 MBps. The 32GB DashDrive UV150 doesn't break any records but puts in an above average performance at an average price. The UV150 isn't a bad drive but despite this, there are far better value for money USB 3.0 drives available in the group test[Feb '14 USBFlashPro]
