Sharing a tablet is a drag, even with Android’s built-in guest mode. You may have separate spaces for apps and logins and data, but those music and movies will still take up space. 

Thus, it’s a blessing that Android allows its users to read and write to outside storage modules. If you’re considering a flash drive for your Android device, SanDisk’s 64GB Ultra Dual USB Drive is an insanely great deal—$30 for only 64GB on Amazon, and about $30-50 everywhere else. (It’s also available in 16GB and 32GB flavors.) You’ll just have to reconcile with the fact that it’s only USB 2.0.

Tiny little flash drive

SanDisk’s 64GB Ultra Dual USB flash drive has covers for each end of the drive.

SanDisk’s Ultra Dual USB Drive is the cutest little flash drive. It’s double-headed, with a regular USB 2.0 connecter on one side, and a microUSB connector on the other. Both ends are shielded by a retractable plastic covering, which can become loose after a few uses. That’s actually the most annoying part of this flash drive—I hurt myself plugging it into my computer because the shield moved, exposing the sharp edges of the microUSB head. 

Tops out at USB 2.0

It took 17 minutes and 40 seconds to transfer over 8.33GB of photos from my MacBook Air to the drive. LG’s own dual-headed 32GB MU1 flash drive was two minutes faster, clocking in at 15 minutes and 34 seconds. Bear in mind that the read and write speeds of both flash drives are held back by the limitations of USB 2.0.

The SanDisk Ultra Dual USB Drive isn’t the most premium storage around, but it sure does hold a lot of stuff. 

You don’t have to set much up to use the drive on your Android device. I plugged it into various devices—including the second-generation Nexus 7, Samsung Galaxy Tab S, HTC One (M8), and the second-generation Moto G—and then downloaded a file manager like Astro File Manager to access the USB directory. (SanDisk offers its own Memory Zone app for “file managing,” but you can manage just fine without it.) I played back episodes of Beverly Hills, 90210 in AVI format; there were some issues with stuttering on some episodes with the Galaxy Tab S, though the Nexus 7, One (M8), and Moto G fared just fine.

Surprise! Sharp edges!

Regardless, it’s extremely convenient being able to plug in a flash drive into your device rather than storing everything locally. SanDisk’s 64GB Ultra Dual USB Drive might not be the fastest, flashiest flash drive out there, but it’s too good of a deal to pass up.
