SED (Self Encrypting Drive)

A self-encrypting drive (SED) is a type of hard disk drive (HDD) or solid-state drive (SSD) that automatically encrypts and decrypts data without requiring user intervention or additional software. Here are the key features and benefits of SEDs:

Automatic Encryption: SEDs use hardware-based encryption to secure all data written to the drive. This process is seamless and does not require any action from the user.

• Security: The encryption keys are stored within the drive, making it difficult for unauthorized users to access the data. If the drive is removed from the system, the data remains encrypted and inaccessible.
• Performance: Since the encryption is handled by the drive’s hardware, there is minimal impact on system performance compared to software-based encryption solutions3.
• Ease of Use: SEDs are designed to be user-friendly, with encryption and decryption processes occurring transparently in the background.
• Data Protection: If a drive is lost or stolen, the data remains protected due to the encryption, reducing the risk of data breaches.
• Disposal: Issuing the erase command is issued, the MEK is erased, rendering the data unrecoverable
  

SEDs are widely used in environments where data security is critical, such as in corporate, government, and healthcare settings.
