'''Hardware-based full disk encryption''' ('''FDE''') is available from many [[hard disk drive]] (HDD) vendors, including: [[Hitachi]], iStorage Limited]], [[Seagate Technology]], [[HitachiSamsung]], [[Western DigitalToshiba]], [[SamsungWestern Digital]], [[ToshibaViasat, Inc.]], [[solid-state drive]] vendors such as [[OCZ Storage Solutions|OCZ]], [[SanDisk]], [[Samsung]], [[Micron Technology|Micron]], [[Integral Memory]] and USB vendors such as [[Yubikey]] or [[iStorage Limited]]. The [[symmetric-key algorithm|symmetric encryption key]] is maintained independently from the [[Central processing unit|CPU]], thus removing computer memory as a potential attack vector. In relation to hard disk drives, the term '''self-encrypting drive''' ('''SED''') is in more common usage.
Hardware-FDE has two major components: the hardware encryptor and the data store.
