Re: Why not encrypt the whole Hard Drives?

Good data, and thanks very much for doing the tests and publishing the results.

With this kind of penalty, however, I have to wonder if the new
Seagate drives and/or the machines that use the TPM chips impose the
same kind of performance penalty, what the administrative overhead is
for each, and the cost differential for using them.

Seen any data on that?
