1. A computer implemented method for copying of data in a storage system between storage drives that have embedded compression, comprising:
providing a compressed data transfer interface in the storage drives;
determining that a copy operation of data is required from a source drive to a target drive wherein the source drive and the target drive use a same compression algorithm;
reading compressed data from the source drive including bypassing a decompression algorithm;
transmitting the compressed data from the source drive to the target drive; and
receiving and writing the compressed data at the target drive including bypassing the compression algorithm at the target drive.
