Move files between USB-C phones and USB-A computers without a cable or cloud upload. The SanDisk 128GB Ultra Dual Drive Go is a 2-in-1 flash drive with a reversible USB Type-C connector on one end and a traditional Type-A connector on the other, so the same 128GB of storage plugs straight into an Android phone, a tablet, a Mac, or an older desktop tower. The drive runs on USB 3.1 Gen 1 with read speeds up to 150MB/s, which makes offloading a folder of 4K clips or a photo library considerably quicker than a USB 2.0 stick. Write speeds are lower and vary by capacity, per SanDisk's own testing…
