disk drives

Disk drives are devices that store and retrieve digital data for computers. They use spinning disks (hard drives) or solid-state memory (SSDs) to save files, software, and the operating system. Hard drives rely on magnetic storage, where data is written and read using magnetic heads as the disks spin rapidly. SSDs use flash memory, similar to USB drives, with no moving parts, making them faster and more durable. The drive's capacity determines how much data it can hold, while its speed affects how quickly you can access or transfer files.
