Many companies tout hard drives with built in encryption as the solution to the Cold Boot Attack. Additionally, these drives are sold as a major step forward in overall data security. In theory, this sounds like a good idea; in practice this could go horribly wrong.
This project is currently in a research state to find different drives that claim to offer specific security properties. It is expected that many products will fail even the most cursory look.
Please add links to products, vendors, standards, prices and places to purchase hardware. At some point, we'll start acquiring hardware to do specific implementation analysis.
Drive manufacturers and specific drive models
- Seagate
- Cheetah® 15K.6 and Cheetah FDE Hard Drives
"The Cheetah 15K.6 FDE drive is available only to major OEM suppliers."

The above whitepaper refers to FIPS 197 certification and the NIST AES Validation List, which informs us that Hitachi uses AES 128 or 256 in ECB mode: Part # 1 entry, 128-bit Part # 4 entry, either 128-bit or 256-bit (NB: large slow HTML table) - Bulk Data Encryption FAQ
