Third-generation SATA interfaces run with a native transfer rate of 6.0&nbsp;Gbit/s; taking [[8b/10b encoding]] into account, the maximum uncoded transfer rate is 4.8&nbsp;Gbit/s (600&nbsp;MB/s). The theoretical burst throughput of SATA 6.0&nbsp;Gbit/s is double that of SATA revision 2.0. It is backward compatible with earlier SATA implementations.<ref name="SATA-600 announce"/>

The SATA&nbsp;3.0 specification contains the following changes:
* 6&nbsp;Gbit/s for scalable performance.
* Continued compatibility with SAS, including SAS 6&nbsp;Gbit/s, as per "a SAS domain may support attachment to and control of unmodified SATA devices connected directly into the SAS domain using the Serial ATA Tunneled Protocol (STP)" from the SATA Revision 3.0 Gold specification.
* Isochronous [[Native Command Queuing]] (NCQ) streaming command to enable [[isochronous signal|isochronous]] quality of service data transfers for streaming digital content applications.
* An NCQ management feature that helps optimize performance by enabling host processing and management of outstanding NCQ commands.
* Improved power management capabilities.
* A small [[low insertion force]] (LIF) connector for more compact 1.8-inch storage devices.
* A 7&nbsp;mm optical disk drive profile for the slimline SATA connector (in addition to the existing 12.7&nbsp;mm and 9.5&nbsp;mm profiles).
* Alignment with the [[International Committee for Information Technology Standards|INCITS]] ATA8-ACS standard.

In general, the enhancements are aimed at improving quality of service for [[streaming media|video streaming]] and high-priority interrupts. In addition, the standard continues to support distances up to one meter. The newer speeds may require higher power consumption for supporting chips, though improved process technologies and power management techniques may mitigate this. The later specification can use existing SATA cables and connectors, though it was reported in 2008 that some [[Original equipment manufacturer|OEM]]s were expected to upgrade host connectors for the higher speeds.<ref>

* [[Shingled magnetic recording]] (SMR) host-control support (device-controlled SMR HDDs are the same as standard CMR HDDs with respect to SATA compatibility). SMR provides a 25 percent or greater increase in hard disk drive capacity by overlapping tracks on the media.
* Optional ''Zoned ATA Command Set'' (ZAC) feature.<ref>ATA/ATAPI Command Set 4 (ACS-4)</ref>
* ''Power Disable'' feature (see PWDIS pin) allows for remote power cycling of SATA drives and a Rebuild Assist function that speeds up the rebuild process to help ease maintenance in the data center.
* Transmitter Emphasis Specification increases interoperability and reliability between host and devices in electrically demanding environments.
* An activity indicator and staggered spin-up can be controlled by the same pin, adding flexibility and providing users with more choices.

The new Power Disable feature (similar to the SAS Power Disable feature) uses Pin 3 of the SATA power connector. Some legacy power supplies that provide 3.3&nbsp;V power on Pin 3 would force drives with Power Disable feature to get stuck in a hard reset condition preventing them from spinning up. The problem can usually be eliminated by using a simple “[[Molex connector|Molex]] to SATA” power adaptor to supply power to these drives.<ref name="power-disable">

* 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.

* Device Transmit Emphasis for Gen 3 PHY: aligns SATA with other characteristics of other I/O measurement solutions to help SATA-IO members with testing and integration.
* Defined Ordered NCQ Commands: allows the host to specify the processing relationships among queued commands and sets the order in which commands are processed in the queue.
* Command Duration Limit Features: reduces latency by allowing the host to define quality of service categories, giving the host more granularity in controlling command properties. The 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.

SATA revision '''3.5a''' was released in March 2021.
