If your power strips are as overloaded as mine with cords and bulky transformers, you’ll be glad to hear that eSATA–a standard that gives external hard drives the data transfer speeds of internal drives–is untethering itself from its power cord.
eSATA is an external version of the Serial ATA technology used to hook up internal PCs, but today external eSATA drives need their own power supply. But on Monday, the Serial ATA International Organization (SATA-IO) announced it’s working on a version that will let external drives draw power over the cable that connects the drive to a computer.
The standard, called Power Over eSATA, is expected to be completed in the second half of 2008, and the first devices supporting the standard could arrive as soon as this year, too, the consortium said. The technology should be able to deliver enough power to run a single 2.5-inch drive, said Knut Grimsrud, the SATA-IO president and an Intel fellow, and likely will become a regular part of eSATA products.
“I would expect the powered eSATA (to) quickly become commonplace for applications where eSATA is used,” Grimsrud said of the new technology.
