The SanDisk Ultra Dual USB Drive is a small thumb drive with a slider that enables you to switch between a USB 3.0 connector and Micro-USB connector.
The SanDisk Ultra Dual USB Drive does a good job at auto-mounting on your Android, assuming you have an OTG-enabled device. In terms of data transfer, it handles large files well. Movies for example, are really easy to transfer to your Android device. You simply copy all of the movies you'd like to transfer into the device's folder and they transfer over to the device itself. You can use the SanDisk Memory Zone app to do all the file copying and moving that you need or you can use any File Viewer app of your choosing.
The Memory Zone App is easy, it selects all files and puts them into categories, and you can easily back up your phone to your flash drive. You can choose to back up your built-in SD or an external SD, and the drive will back up photos, contacts, documents, movies and music.
