SATA-IO Expands Supported Features

SATA continues to grow in functionality and market reach

The Serial ATA International Organization (SATA-IO), the consortium dedicated to sustaining the quality, integrity and dissemination of the Serial ATA (SATA™) technology, announced publication of the SATA Revision 3.3 Specification and Unified Test Document (UTD) 1.5. The latest SATA specification introduces new features that enable higher capacity, reliability and flexibility for SATA-based products.

The relentless growth of digital data continues to drive demand for higher capacity, lower-cost storage. Shingled Magnetic Recording (SMR) overlaps HDD tracks to yield a 25 percent capacity increase versus conventional magnetic recording technology. SATA-IO has incorporated SMR support into its new specification.

Additional advancements in the revision 3.3 specification include:

• Power Disable: Allows for remote power cycling of SATA drives to help ease maintenance in the data center.

• Single-Pin Activity Indicator and Spin-Up Control: An activity indicator and staggered spin-up can be controlled by the same pin, adding flexibility and providing users with more choices.

• Transmitter Emphasis Specification: A new transmitter specification increases interoperability and reliability in electrically demanding environments.

“As the organization responsible for an industry standard, SATA-IO understands the need to support an evolving storage market. We believe the revision 3.3 specification provides higher capacity, better reliability and more flexibility to users,” said Knut Grimsrud, SATA-IO president and chairman.
