Hard Drives

A hard drive is a device used in computers to store data permanently, similar to a digital filing cabinet. It contains spinning disks coated with a magnetic material where information such as documents, photos, and programs are recorded and retrieved using read/write heads. Hard drives come in various sizes and speeds, with traditional models (HDDs) offering large storage at a lower cost, and newer solid-state drives (SSDs) providing faster performance with no moving parts. Overall, hard drives are essential for saving and accessing data over time, ensuring your computer keeps all your files safe even when powered off.
