Does this offer more security than hardware encryption e.g. in latest Intel and Samsung drives? These drives can transparently encrypt all the content with 256-bit AES; the password is ATA password.
They lost me at "Firstly the encryption key is flipped". What does this mean?
Encrypted drives typically store the literal en/decryption key (derived from your password or credentials) and whatever salt is necessary on a chip. Nuking that information effectively makes your data unrecoverable, because it's no longer distinguishable from noise.
I assume "flipped" is a translation error for "cleared" or "randomized", especially given typos like "instantaineously".
I always wonder why this kind of drive-internal encryption comes up in serious discussions. To me it makes no sense whatsoever: I have no way of checking if the drive actually encrypts the data, I don't know what happens to my password, where is it stored, who else gets access to it (or my data), etc.
How can anyone consider this "transparent" encryption to be secure?

And that is before you consider back doors and the like
