The Serial ATA International Organization (SATA-IO) today 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 specification for the popular Serial ATA storage interface will double the maximum transfer speed from three to six gigabits per second (Gbps).
Developers can now begin designing products based on SATA 6Gbps 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, preserving its inherent cost-conscious design while minimizing changes to existing implementations and infrastructures. The same cables and connectors used for current SATA implementations can be used to connect SATA 6Gbps devices, although SATA-IO recommends utilizing quality components to ensure data integrity and robust operation at the fast 6Gbps transfer rate.
"Fast transfer rates, low cost and efficient protocol have made SATA the mainstream storage interface of choice," said Knut Grimsrud, SATA-IO president. "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."
