HDD

Hard Disk Drive

A type of computer storage device that uses magnetic storage to store and retrieve digital information.

An HDD consists of one or more spinning disks or platters that are coated with a magnetic material. Data is written to and read from the disks using a read/write head that moves back and forth over the surface of the disk.

HDDs are commonly used in desktop and laptop computers as the primary storage device for operating systems, applications, and user data. They are also used in servers, storage arrays, and other data storage systems.

The capacity of an HDD is determined by the number of platters it contains and the density of the data that can be written to each platter. Modern HDDs can store several terabytes of data, making them ideal for storing large files such as photos, videos, and databases.

HDDs are known for their relatively slow read and write speeds compared to other types of storage, such as solid-state drives (SSDs), but they remain popular due to their low cost, high capacity, and long-term reliability. However, as technology advances, solid-state drives are becoming increasingly popular due to their faster read and write speeds and lower power consumption.
