Does encryption slow down Linux?

Encrypting a disk CAN make it slower. For example, if you have an SSD capable of 500mb/sec and then do full disk encryption on it using some crazy long algorithm you might get FAR below that max of 500mb/sec. ... There is CPU/Memory overhead for any encryption scheme.
