If an adversary has physical access to a computer, they can get basically anything. In unencrypted scenarios they can pull out drives and mount them in their own run time (OS). If the device is also running then coldboot attacks can allow the encryption to be attacked. Finally, there is the eventual cracking of many encryption algorithms via cryptanalysis and moores law.
