SanDisk Ultra Dual Drive m3.0 32GB to 256GB Flash Drive

About the SanDisk Ultra Dual Drive m3.0

Older Android phones with a micro-USB port and OTG support are what the m3.0 is built for. One end plugs into your phone, the other into a USB-A port on your computer, and both slide back into the body. You can choose 32GB, 64GB or 256GB.

SanDisk rates transfers from drive to computer at up to 150 MB/s on the 32GB and 64GB and up to 130 MB/s on the 256GB. Writes are lower. Once you set it up, the Memory Zone app from Google Play backs up your photos and videos to the drive by itself.
