- Disk Drive
A disk drive is a data storage device used for storing and retrieving digital information, traditionally using one or more rigid ( ‘hard ‘) rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. Disk Drives (Hard Disk Drive, Solid State Drive, Hybrid) are a type of non-volatile memory, retaining stored data even when powered off.
