hard disk drives (HDDs)

Hard disk drives (HDDs) are storage devices used in computers to save data permanently. They consist of spinning magnetic disks (platters) and read/write heads that move across the disks to access information. Data is stored magnetically in tiny regions, allowing the HDD to retain information even when powered off. Faster and more affordable than some alternatives, HDDs are commonly used for storing large amounts of data, like documents, photos, and videos. Despite being slower than solid-state drives (SSDs), they offer a cost-effective solution for extensive data storage needs.
