Dual USB 3.0 and micro-USB drive

The SanDisk Ultra Dual Drive M3.0 combines a USB 3.0 Type-A connector and a micro-USB OTG connector in a single 64 GB flash drive. It lets Android phones, tablets and computers exchange files without cables or cloud services. The black housing slides to reveal either interface.

Upgrade from single-connector sticks

If you currently carry separate drives for USB-A ports and micro-USB devices, this replaces both. The jump is worth it when you move large media libraries between a laptop and an Android device daily. Users who only transfer small documents or who already use USB-C devices will not benefit.

USB 3.0 speed ceiling

The drive reads at up to 150 MB/s over USB 3.0; write speeds and micro-USB 2.0 transfers are slower. The micro-USB port is limited to USB 2.0 signalling, so OTG file moves on older phones will not reach the quoted peak. No hardware encryption or password protection is included.

Questions about this item

Does the SanDisk Ultra Dual Drive M3.0 fit a phone with a micro-USB port?

The drive has a micro-USB connector for Android devices with OTG support and a standard USB 3.0 plug for computers.

How do I install the SanDisk Ultra Dual Drive M3.0 on my Android phone?

Insert the micro-USB end into the phone, allow the file-manager prompt, then copy files; the step often missed is granting storage permission in the system dialog.

When should I replace the SanDisk Ultra Dual Drive M3.0?

Replace the 64GB drive when it no longer reaches the 150MB/s read speed, shows write errors, or the sliding mechanism fails to protect both connectors.
