Hardware-based full disk encryption (FDE) is available from many hard disk drive (HDD) vendors, including: Seagate Technology, Hitachi, Western Digital, Samsung, Toshiba and also solid-state drive vendors such as Samsung, Micron and Integral. 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.
Hardware-FDE has 2 major components: the hardware encryptor and the data store. There are currently 3 varieties of hardware-FDE in common use:
- Hard Disk Drive (HDD) FDE (usually referred to as SED)
- Enclosed hard disk drive FDE
- Bridge and Chipset (BC) FDE

Famous quotes containing the words full and/or disk:
“With my desire to write he seemed in full sympathy, and in urging our early marriage he argued that my first necessity was leisure in which to develop and to master my craft. It appeared to me that with such a man as teacher and guide I could not fail, and it was in a queer mixture of young love and vaulting ambition that I became a wife.”
—Rheta Childe Dorr (1866–1948)
“Unloved, that beech will gather brown,
This maple burn itself away;
Unloved, the sun-flower, shining fair,
Ray round with flames her disk of seed,
And many a rose-carnation feed
With summer spice the humming air;”
—Alfred Tennyson (1809–1892)
