The Black Series from Western Digital is designed for high-performance systems and offers correspondingly high transfer rates. This is a version of the Black with a modern SATA 6G connection. While the limit of the SATA 2 connection at 150 MB/s has not yet been fully utilized, the SATA 6G implemented here not only provides the advantage of higher bandwidth. The protocol has also been significantly refined to enhance energy efficiency and optimize the transmission of multiple simultaneous high-bandwidth data streams.
