Hello All,

A Japanese article that discuss merits of making encryption part of HDDs:

English Summary:
In software encryption, the security-key and password is controlled
above the OS. Therefore the security is not perfect. Also with
software based solutions, full encryption is not possible, because the
encryption process creates temporary files. With hardware based
solutions this is not a problem since the security-key and password in
a separate part of the HDD, and no need for temporary files. Plus
hardware encryption is a lot faster then software enryption.

The article also describe how the Full Encryption Discs  <

work. Essentially they use RSA algorithm with 192-bit key.
