  • storing a non-transformed logical data object (LO) in a storage device;

    logically dividing the non-transformed LO into a non-transformed first segment and one or more non-transformed subsequent segments in response to a respective transformation request;

    generating a header for the non-transformed LO;

    transforming the non-transformed first segment to generate a transformed first segment comprising data in transformed form; and

    overwriting the non-transformed first segment in the storage device with the header and the transformed first segment if a combined size of the header and the transformed first segment is less than a predefined size.
