Self-Encrypting Drive (SED) technology provides verified and certified data security which offers nearly unbreakable pre-boot access protection for user data. Because SED access is pre-boot, there is no possibility of running an OS utility to break authentication codes. Following TCG Opal 2.0 specifications and IEEE-1667 access authentication protocols provide data security which meets government standards for data in banking, finance, medical and government applications. Support for Windows 10 eDrive provides the individual user with simple plug-and-play data security which can protect sensitive personal data, without having to modify BIOS settings, and without having to spend time to encrypt data already in place (as is the case for software encryption methods).
Since Windows 8 Professional, Enterprise, and RT editions all automatically support encryption key management of SEDs. Depends on manufacturer settings, usually and mostly SEDs will support Microsoft’s requirements for eDrive capability. This provides security for data at rest with no loss of throughput performance. In other words, in order to active the password feature, to arm the security system if you will, all it takes in Windows 10 is to enable Bitlocker. While Bitlocker in older Windows Operating Systems does not support SED technology, you can still use Bitlocker like on any other drive, it just won’t take advantage of the benefits of the hardware encryption on the SED. To help users on Windows 7 or other Operating Systems take advantage of the SED ability third-party software vendors, such as Wave Systems, WinMagic, and others provide advanced encryption and authentication management features for Opal 2.0 storage devices.
With SED, it will means that all data is always encrypted by the controller when written to the NAND and decrypted when read. Windows 10 Bitlocker, along with other products, can work with this built-in hardware encryption ability when you apply a password in Windows.
