What is Full-Disk Encryption (FDE) and What are Self-Encrypting Drives (SED)?

Full-Disk Encryption (FDE) is a method of encrypting all data on a storage device, such as a hard drive or flash drive. It encrypts every file, folder, and a bit of free space on the disk.

This type of encryption is typically used to secure laptops, desktop computers, and other portable devices that may be lost or stolen.

Self-Encrypting Drives (SED) are a type of hard drive with encryption and decryption capabilities built into the drive hardware. The process is handled directly by the drive rather than by software on the host device.

This can provide an added layer of security, as it eliminates the need for software that could be vulnerable to malware or other types of attacks.

Additionally, SEDs can automatically encrypt and decrypt data as it is written to and read from the drive, making it more secure and convenient.
