    Solid-state drive - Wikipedia

    A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, and solid-state disk. SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The … See more

    An SSD stores data in semiconductor cells, with its properties varying according to the number of bits stored in each cell (between 1 and 4). Single-level cells (SLC) store one bit of data … See more
