Self-Encrypting Drive (SED): A storage device that automatically encrypts the data it contains without requiring any action from the user. It employs hardware-based encryption, where the encryption key is never stored in the computer’s operating system. Instead, the key is kept within the drive’s controller. This feature offers significant protection against data breaches, especially in cases where physical drives are lost or stolen, as it renders the data unreadable without the correct encryption key.
