if you own a ThinkPad already, why don't you use the built-in HD
encryption based on the TPM? You can set a password in the BIOS,
and the encryption is totally transparent to any OS you use. I
use it a lot on machines with dual or multi boot. The *whole
disk* is encrypted, and none of the OSes knows about it. I must
admit that I never tested w/ SSD so far, so I don't know if there
is any impact.
