Hardware-based full disk encryption

Hardware-based full disk encryption (FDE) is available from many hard disk drive (HDD) vendors, including: iStorage Limited, Seagate Technology, Hitachi, Western Digital, Samsung, Toshiba and also solid-state drive vendors such as OCZ, SanDisk, Samsung, Micron and Integral Memory. The symmetric encryption key is maintained independently from the 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.
