Specification 3.5 introduces features that enhance productivity and help integrate SATA devices and products with other industry-standard I / O standards.
SATA Revision 3.5 specification published
“SATA-IO has a long tradition of participating in the industry and supporting new innovative technologies. These new features underscore the versatility of the SATA standard, as Jim Hatfield, President of SATA-IO, described the new version of the standard. “SATA remains one of the most stable but adaptable interfaces in the industry. We are pleased to be able to extend the benefits of SATA compatibility for our members and the industry by adding features that allow SATA and other I / O standards to coexist in a variety of environments. ”
The following features have been added to the spec:
- Device Transmit Emphasis for Gen 3 PHY – Equals SATA with other I / O measurement solutions to help SATA-IO participants in testing and integration.
- Defined Ordered NCQ Commands – Allows the host to specify the relationship between the commands in the queue and sets the order in which they are processed.
- Command Duration Limit Features – reduce latency by allowing the host to define the quality of service categories, providing it with more granular control over the properties of commands. This feature helps align SATA with the Fast Fail requirements established by the Open Compute Project (OCP) and specified in the INCITS T13 Technical Committee standard.
In addition, the 3.5 specification includes all the latest updates to the T13 standard to provide developers with the latest requirements for drives and other products, as well as various fixes and refinements to the previous SATA 3.4 specification.
The specification is available to SATA-IO members for free, others can purchase it.
