SanDisk launches prototype 4TB Flash Drive

Western Digital’s SanDisk brand unveiled a prototype flash drive, which it says is the world’s highest capacity USB drive featuring total of 4TB of storage. Equipped with a USB-C connector, the flash drive is a prototype and thus it’s not yet for sale. A 4TB USB-sized flash drive would be prohibitively expensive as even 2TB flash drives cost upwards of $1,000, but it does demonstrate advances in storage technology.
