SanDisk Ultra Dual Drive m3.0 Review

To use the drive, you need to install the `SanDisk Memory Zone app for Android (available on Google Play) that helps you manage your device’s memory and your content. The Dual Drive m3.0 is compatible with Android smartphones and tablets featuring OTG (On-The-Go) USB support. The SanDisk Memory Zone app lets you view, access, and back up all the files from your phone’s memory in one location. It can also automatically move files from your device to your drive to free up space.


SanDisk claims to offer up to 150MB/s of high transfer speed with the drive and it seems to deliver the same. We tested its performance in real life and it’s really impressive. Transferring files such as photos and files were real quick. We transfer the 5 GB of assorted data from PC to drive and it took about 5 min and 51 sec. while transferring the same data from USB to PC it took 7 min 38 sec. While running CrystalDisk Mark benchmark it delivered, 108 MB/sec read speed of 34.68 MB/sec write speed.
