'''Hardware-based full disk encryptionencrption''' ('''FDE''') is available from many [[hard disk drive]] (HDD/[[Solid-state drive|SSD]]) vendors, including: ClevX, [[Hitachi]], Integral Memory, iStorage Limited, [[Micron Technology|Micron]], [[Seagate Technology]], [[Samsung]], [[Toshiba]], [[ViaSat|Viasat UK]], [[Western Digital]]. The [[symmetric-key algorithm|symmetric encryption key]] is maintained independently from the computer's [[Central processing unit|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.
