A hard disk drive, often abbreviated as HDD, is a non-volatile storage device that stores digital data using magnetic storage. Data is stored on rotating platters coated with a magnetic material. Read/write heads, mounted on an actuator arm, move across the surface of these platters to access and modify data. The speed at which the platters rotate, measured in revolutions per minute (RPM), is a key factor in determining the drive's performance. HDDs were the primary form of mass storage in computers for decades due to their relatively low cost per gigabyte and high storage capacities. They are still widely used today for bulk storage in desktop computers, servers, and external storage solutions where cost-effectiveness and large capacities are prioritized. While solid-state drives (SSDs) offer faster performance and greater durability, HDDs remain a relevant technology for many applications.
