3D NAND

3D NAND is a type of data storage technology used in modern solid-state drives (SSDs). Unlike traditional NAND, which arranges memory cells in a flat, two-dimensional layer, 3D NAND stacks multiple layers of memory cells vertically. This stacking allows for higher storage density, meaning more data can be stored in a smaller space, and improves performance and durability. Essentially, 3D NAND is like building many floors of tiny memory apartments stacked high, enabling faster access, greater capacity, and longer lifespan in devices such as laptops and smartphones.
