hard disk drive (HDD)

A hard disk drive (HDD) is a device used for storing digital information in computers and other electronic devices. It consists of one or more spinning disks coated with a magnetic material, where data is written and read by a moving arm equipped with a read/write head. HDDs are known for their large storage capacity and cost-effectiveness, making them suitable for storing files like documents, photos, and videos. However, they are generally slower and more prone to mechanical failure compared to solid-state drives (SSDs), which use flash memory technology for storage.
