SanDisk Ultra Dual USB Drive: Android file transfers made easy

Michael Brown | Feb. 14, 2014
The two-headed thumb drive can be used with Android smartphones, tablets and PCs.

Press and hold a file name, and a pop-up menu will appear giving you the option to copy the file to another storage device or to your cloud account. You can also rename or delete the file, make the file private (these are password protected), or share the file on Facebook. Memory Zone also has a backup/restore function that you can set to automatically back up all or selected files from your phone to a USB storage device or--more practically--to your cloud-storage service.

This element of the app informs you of the backup's progress, how fast files are being transferred, and an estimated time of completion. Backups can be performed over a 4G connection or limited to using Wi-Fi, so they don't suck up your cellular data quota.

SanDisk's Ultra Dual USB Drive would be a lot faster if it were outfitted with a USB 3.0 interface, but that would also make it more expensive. It's already a bit pricey, with the 32GB model selling for $30. That's a $10 premium over a conventional 32GB USB thumb drive, and you can buy a 10-foot micro USB cable for as little as a buck and a half. (SanDisk also offers 16GB Dual USB drives for $20, and 64GB drives for $50). But a cable isn't nearly as convenient.

SanDisk isn't the first company to hit on the idea of a two-headed storage device. Sony announced its own line of two-in-one drives last December. But Sony's models top out at 32GB, and the company doesn't offer an Android file manager.
