Serial ATA powers up

The Serial ATA International Organization has begun work on a new specification that will provide power to external SATA devices without the need for a separate power connection, filling a small but significant hole in its coverage for the successful storage interconnect. Devices based on the spec could hit the market before the end of the year, enabling a new class of portable, external SATA hard disk and optical drives.

The new spec will provide power for a single drive directly from the host system using a Power-Over-eSATA cable. The cable will maintain compatibility with the existing eSATA connector form factor and the current maximum interface transfer rate of 3Gbits/second.
