The Serial ATA International Organization (SATA-IO), the storage industry consortium dedicated to sustaining the quality, integrity and dissemination of the Serial ATA (SATA ) technology, announced the publication of the SATA Revision 3.4 Specification. The newest SATA specification introduces features that enable monitoring of device conditions and execution of housekeeping tasks, both with minimal impact on performance.

The storage market continues to demand improvements in performance, reliability and compatibility.

The industry standard group has added new features to the specification revision 3.4 so that SATA devices may offer improvements in these areas, including:

  • Durable /Ordered Write Notification: enables writing selected critical cache data to the media, minimizing impact on normal operations.
  • Device Temperature Monitoring: allows for active monitoring of SATA device temperature and other conditions without impacting normal operation by utilizing the SFF-8609 standard for out of band (OOB) communications.
  • Device Sleep Signal Timing: provides additional definition to enhance compatibility between manufacturers’ implementations.
