Starting with Windows Server 2012 and Windows 8, Microsoft has complemented BitLocker with the Microsoft Encrypted Hard Drive specification, which allows the cryptographic operations of BitLocker encryption to be offloaded to the storage device's hardware, for example, self-encrypting drives.
The symmetric encryption key is maintained independently from the computer's CPU, thus allowing the complete data store to be encrypted and removing computer memory as a potential attack vector. Hardware-FDE has two major components: the hardware encryptor and the data store. There are currently four varieties of hardware-FDE in common use:

Disk encryption is a technology which protects information by converting it into code that cannot be deciphered easily by unauthorized people or processes. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. It is used to prevent unauthorized access to data storage. [1]
The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux.. LUKS implements a platform-independent standard on-disk format for use in various tools.
The Opal SSC (Security Subsystem Class) is an implementation profile for Storage Devices built to: Protect the confidentiality of stored user data against unauthorized access once it leaves the owner's control (involving a power cycle and subsequent deauthentication).
A hardware security module (HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys), and performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1]
Some disk encryption software (e.g., TrueCrypt or BestCrypt) provide features that generally cannot be accomplished with disk hardware encryption: the ability to mount "container" files as encrypted logical disks with their own file system; and encrypted logical "inner" volumes which are secretly hidden within the free space of the more obvious ...
