PQI U819V (Flash)

Intelligent Drive Micro USB 3.0 16GB

▲ 50375 ▼

Release date: Q4 2012.

Average Bench: 10.8% (409th of 639)

Based on 367 user benchmarks.  Device: VID 3538 PID 0901 Model: Generic USB Flash Disk

The PQI Micro is not a fast performer, in fact, it's the slowest USB 3.0 thumb drive we have reviewed to date and it's also considerably over priced. There is however one saving grace for this drive, its form factor is by far the smallest we have ever seen on a USB 3.0 drive. Every single dimension (length, breadth, height, volume, weight) comes in lower than the USB 3.0 competition. So if you want a tiny USB 3.0 thumb drive and you can live with relatively slow performance then this could be the drive for you. We would suggest checking the various micro USB 2.0 options before purchasing this drive, you might find better value for money with only slightly slower performance. [Feb '13 USBFlashPro]
