An HDD is a magnetic storage device that holds data on spinning platters. It has been used for decades due to its large capacity, stable performance, and affordability.

How HDD Works When asking \u201cwhat is HDD\u201d, it refers to the overall mechanism used for magnetic data storage: Platters coated with magnetic material store data bit-by-bit.
