SATA ditching power cables
The Serial ATA International Organisation (SATA-IO) is working on a new specification to provide power to external SATA devices, without the need for a separate power source.
At the moment, eSATA devices – which include external hard disk drives and portable optical drives – need an extra power source. Under the Power Over eSATA initiative, a specially designed cable would provide power from the host machine.
“Enhancing eSATA with power delivery will provide a new level of convenience to the designer and the end user,” says Knut Grimsrud, SATA-IO’s president. “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.”
The Power Over eSATA cable would remain compatible with existing connector form factors and keep the current maximum transfer rate of three gigabits per second, SATA-IO claims.
The technology is expected to be rolled out in the second half of the year.
