Serial ATA International Organization (SATA-IO), the consortium dedicated to sustaining the quality, integrity and dissemination of SATA technology, recently released to its members the physical layer (PHY) portion for its third generation storage interface, which will be defined in the upcoming SATA Revision 3.0 specification. This release ushers in a new generation of faster SATA 6Gb/s products. Developers can now begin designing products based on SATA 6Gb/s technology as work continues on the SATA Revision 3.0 specification, which is expected to be completed in the second half of 2008. Various SATA-IO work groups are engaged in the process of readying new features for incorporation in the final version of the SATA Revision 3.0 specification. These features will include advances for data streaming and better power management.
The new industry standard will enhance the appeal of the high-performance, low-cost interface, solidifying its prevalence as a long-term storage interface. According to John Rydning, IDC’s research director for hard disk drives, SATA has become the primary storage interface with more than 650 million SATA hard disk drives shipped since its introduction in 2001. He added that more than three-quarters of new desktop and mobile PC systems shipped in 2007 were equipped with SATA hard drives. Other devices adopting the SATA interface technology include optical disk drives, solid state drives and multi-user storage applications. Many entry and mid-level servers as well as external storage systems now feature the technology.
“Fast transfer rates, low cost and efficient protocol have made SATA the mainstream storage interface of choice,” said Knut Grimsrud, SATA-IO president and Intel Fellow. “By doubling transfer speeds while maintaining backward compatibility, the new specification will make Serial ATA an even more attractive solution for consumers and businesses alike.”
To accompany the new SATA Revision 3.0 specification, the industry organization has introduced a new
logo that can be used to easily identify SATA 6Gb/s-enabled products.
