A new specification for the popular Serial ATA storage interface will double the maximum transfer speed from three to six gigabits per second (Gb/s).
This will enable large amounts of data to be moved at even faster rates, a key advantage as end-users amass ever-increasing amounts of high-resolution photos, videos, music and other multimedia files.
Serial ATA International Organization (SATA-IO), the consortium dedicated to sustaining the quality, integrity and dissemination of SATA technology, has 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. The new 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 specification will maintain the low cost and low power for which the popular storage interface is acclaimed. In addition, backward compatibility with earlier SATA implementations will be maintained by keeping the existing SATA connector configuration. The same cables and connectors
used for current SATA implementations can be used to connect SATA 6Gb/s devices, although SATA-IO recommends utilizing quality components to ensure data integrity and robust operation at the fast 6Gb/s transfer rate.
SATA-IO will demonstrate implementations of its new 6Gb/s technology at the Intel Developer Forum
(IDF) this week.
