* [[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">
