A data storage device is a hardware component used to record, store, and retrieve digital information. These devices come in various forms, including hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, CDs, DVDs, and memory cards. Data storage devices are essential for both personal and business computing, enabling users to save files, applications, and system backups securely. In cybersecurity, protecting data storage devices is vital to prevent unauthorized access, data breaches, and loss of sensitive information. Encryption, access controls, and regular backups are common security measures applied to these devices.
