Just got this Sandisk Ultra Dual USB Drive 3.0 from the computer store last week for some file transfer purpose. The extra micro USB connector on this flash drive comes in handy when I need to transfer file to or from a tablet/smartphone. This is convenient because I don't need an extra USB cable/OTG cable to do it.
USB OTG connection to smartphone.
Here's a screenshot of the CrystalDiskMark (version 4.0.3 ) results.
The only downside to this flash drive is the iffy sliding mechanism. Push the flash drive too hard, it slides back in.
