Jan 14 — The consortium dedicated to sustaining the quality, integrity and dissemination of SATA technology, Serial ATA International Organization (SATA-IO), announced its Power Over eSATA initiative. SATA-IO has begun work on a new specification that will provide power to external SATA (eSATA) devices without the need for a separate power connection. Led by the organization’s Cable and Connector group, the specification is targeted for completion in the second half of 2008.

Currently, eSATA devices require an external power adapter to supply the necessary voltage for operation. The new SATA-IO specification is designed to eliminate this requirement by providing power for a single drive directly from the host system using the Power Over eSATA cable. Key benefits will be to maintain compatibility with the existing eSATA connector form factor and retain high performance at the current maximum interface transfer rate of 3Gb/s (gigabits per second).

“Its fast transfer rate and efficient protocol makes eSATA the highest performing external mainstream storage connection,” said Knut Grimsrud, SATA-IO president and Intel Fellow. “Enhancing eSATA with power delivery will provide a new level of convenience to the designer and the end user. By eliminating the need for a separate power connection, customers can more easily expand their storage, making Serial ATA an even more attractive solution for mainstream storage applications.”

Power Over eSATA solutions are expected to be available on the market as soon as the second half of 2008, creating new business opportunities by using either a SATA Hard Disk Drive or a SATA Optical Drive in a portable external enclosure. This gives consumers the option of carrying their digital content portably in addition to using these external devices for data back-up purposes.
