SATA III is a new version of Serial ATA International (SATA-IO) officially released in 2009. The official name is SATA Revision 3.0, which is mainly to double the transmission speed to 6Gbps, and is backward compatible with the old version of "SATARevision2.6" (also It is now commonly known as SATA3Gbps), and the interface and data lines have not changed.
III Developed by Serial ATA International, dated May 26, 2009 Feature doubled to 6Gb/s compared to version 2.0 Serial ATA International (SATA-IO) SATA-IO announced on May 26, 2009 Completing the final SATA III specification, in addition to the 2.0 version, the bandwidth has doubled to 6Gb/s, and a number of new technologies have been added, including new NCQ instructions to improve the transmission technology and reduce the power consumption during transmission.  According to the SATA III specification white paper, in addition to the bandwidth up to 6Gb/s, SATA III will increase the number of NCQ instructions, including priority processing for immediate resources, mainly for video and audio and video transmission. In addition, SATA III will prioritize the resources being processed by the system, which greatly improves the system's execution efficiency. In order to improve battery life, SATA III adopts the new INCITS ATA8-ACS standard and is compatible with the old SATA devices, which not only further improves the transmission signal technology, but also greatly reduces the power consumption required for SATA transmission. In response to the current NB market demand for reduced product size, SATA III offers a smaller LIF interface (Low Insertion Force Connector) than the general SATA interface, specifically for 1.8-inch storage devices, including the upcoming 7mm thick disk drive.
SATA 3.4 standard officially released: hard drive is healthier
SATA-IO has announced the release of the latest SATA Revision 3.4 standard specification, which introduces features such as device status monitoring and cleanup task execution with minimal impact on performance.
SATA-IO said that the storage industry has always wanted better performance, reliability, and compatibility. To this end, the SATA 3.4 standard adds several new features to meet demand, including:
1, Durable / Ordered Write Notification (Durable / Ordered Write Notification)
Specific key cache data can be written to the hard disk with minimal impact on day-to-day operations.
2. Device Temperature Monitoring
Out-of-band data (ODB) communication utilizes the SFF-8690 standard to dynamically monitor the temperature of SATA devices, etc., without affecting daily operation.
3, device sleep signal timing (Device Sleep Signal Timing)
Add more definitions to enhance compatibility between different vendors.
4. Other corrections and clarifications regarding the SATA standard
The SATA 3.0 standard was released on May 26, 2009, which is SATA 6Gbps. It was upgraded to SATA 3.1 in July 2011, upgraded to SATA 3.2 in August 2013, and upgraded to SATA 3.3 in February 2016. It has been adding new features. , optimize device support.
