Just get a box with a supported very-high-speed AES hardware accelerator (e.g. recent amd64/x86-64 processors with AES-NI), and tune your dm-crypt usage to cyphers that can be hardware accelerated. Even single-threaded AES-NI dm-crypt would be much faster than multithreaded non-accelerated dm-crypt, AFAIK. > Some manufacturers make hard drives with built-in encryption.

Yes, although it often requires proper support from the EFI/BIOS for it to be usable in the boot device (and also on the image device when using suspend-to-disk). YMMV. > Any other comments or suggestions? You better do your homework if you're going to trust the vendors of self-encripting devices. -- "One disk to rule them all, One disk to find them.
