At CES 2018, SanDisk showed off a prototype of what is supposed to be the world’s smallest 1TB USB-C flash drive.
SanDisk’s slimmed-down prototype is far smaller than Kingston’s 2TB DataTraveler Ultimate GT. In addition, the SanDisk prototype fully embraces USB-C, instead of the old USB 3.0. That means you’ll be able to use it to directly transfer storage to Android phones and computers.

With no price or release date announced, for now, this drive is just a prototype. Considering a full-sized 1TB USB-C SSD already costs around $350, it’s less likely that SanDisk’s prototype will be affordable should it become available right now.
