Useful for travelling with essential data – This small, dual port (USB & USB-Micro), 256GB thumbdrive holds all the data I need from my desktop while I’m traveling with my phone that it also plugs into. My new phone has a USB-C port instead of a USB-Micro, so I adapted it using a USB Micro-to-USB-C converter. It works well in both devices and use it to transfer files between them. It’s compact enough to hide on your person while travelling.

Decent Flash Drive for Certain Applications – The micro USB connection will not fit all devices due to the housing of the flash drive getting in the way. Otherwise, the flash drive works as advertised with decent read/write speeds given its size.
