You can hold all the data in the American Library of Congress AND all the data from Wikipedia on a small stack of solid-state drives especially considering a single SSD's capacity can reach up to 30 TB of data. In this video, we'll explore how tens of terabytes can be crammed into such a small space. This technology is called 3D NAND, and specifically, we'll explore the physics and concepts on how 3 bits of information can be written to and read from individual cells.
