A standard hard disk drive is a non-volatile storage that retains stored data even when powered off. It is a data storage device that uses magnetic storage to store and retrieve the data. Rapidly rotating disks or platters coated with magnetic material are used to perform these operations. Data is accessed in a random-access manner, thus making it slow. Individual blocks can be stored or retrieved in any order and not only sequentially.
