In an illustrative embodiment, a method, computer program product, and apparatus for managing encryption of data are provided. The method comprises determining whether the number of data units contains a known pattern responsive to receiving a number of data units to write to a storage device; storing the number of data units on the storage device in an unencrypted form responsive to a determination that the number of data units contains the known pattern; encrypting the number of data units to form encrypted data units responsive to an absence of a determination that the data contains the known pattern; and storing the encrypted data units on the storage device.
