If your SSD supports encryption "in hardware", and you don't need to
protect your data against any entity likely to be able to break or
backdoor that implementation, then that's an obvious choice.
Advantages: No performance impact whatsoever (the SSD will run your data
through the same encryption controller whether or not you set a
password). OS independent. Encrypting everything, including the boot
loader and boot loader configuration.
