Editing SATA (section)

== Revisions ==
SATA revisions are typically designated with a dash followed by [[Roman numerals]], e.g. "SATA-III",<ref>{{cite web|url=http://kb.sandisk.com/app/answers/detail/a_id/8142/~/difference-between-sata-i,-sata-ii-and-sata-iii| archive-url=https://web.archive.org/web/20211129075859/https://kb.sandisk.com/app/answers/detail/a_id/8142/~/difference-between-sata-i%2C-sata-ii-and-sata-iii|archive-date=2021-11-29| website=www.sandisk.com| access-date=2023-08-17| title=Difference between SATA I, SATA II and SATA III}}</ref> to avoid confusion with the speed, which is always displayed in [[Arabic numerals]], e.g. "SATA 6 [[Gigabit|Gbit]]/[[Second|s]]". The speeds given are the ''[[Data signaling rate|raw interface rate]]'' in Gbit/s including [[line code]] overhead, and the ''[[Goodput|usable data rate]]'' in [[Megabyte|MB]]/s without overhead.

=== SATA revision 1.0 (1.5&nbsp;Gbit/s, 150&nbsp;MB/s, Serial ATA-150) <span class="anchor" id="1.0"></span> ===
Revision 1.0a<ref name="SATA1a" /> was released on January 7, 2003. First-generation SATA interfaces, now known as SATA 1.5&nbsp;Gbit/s, communicate at a rate of 1.5&nbsp;Gbit/s, and do not support [[Native Command Queuing]] (NCQ). Taking [[8b/10b encoding]] overhead into account, they have an actual [[uncoded transfer rate]] of 1.2&nbsp;Gbit/s (150&nbsp;MB/s). The theoretical burst throughput of SATA 1.5&nbsp;Gbit/s is similar to that of [[Parallel ATA|PATA]]/133, but newer SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment.

During the initial period after SATA 1.5&nbsp;Gbit/s finalization, adapter and drive manufacturers used a "bridge chip" to convert existing PATA designs for use with the SATA interface. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and, in general, perform identically to their native-SATA equivalents.<ref>

{{As of|2010|4}}, the fastest 10,000&nbsp;rpm SATA [[hard disk drive]]s could transfer data at maximum (not average) rates of up to 157&nbsp;MB/s,<ref name="Tom2010HardDrives">{{Cite news|title=VelociRaptor Returns: 6Gbit/s, 600GB, And 10,000 RPM  |website=tomshardware.com |author=Patrick Schmid and Achim Roos |url=http://www.tomshardware.com/reviews/wd6000hlhx-velociraptor-600gb,2600-5.html |date=2010-04-06 |access-date=2010-06-26}}</ref> which is beyond the capabilities of the older PATA/133 specification and also exceeds the capabilities of SATA 1.5&nbsp;Gbit/s.

=== SATA revision 2.0 (3&nbsp;Gbit/s, 300&nbsp;MB/s, Serial ATA-300) <span class="anchor" id="2.0"></span> ===
[[File:SATA2.jpg|thumb|SATA 2 connectors on a computer motherboard, all but two with cables plugged in. Note that there is no visible difference, other than the labeling, between SATA 1, SATA 2, and SATA 3 cables and connectors.]]
SATA revision 2.0 was released in April 2004, introducing Native Command Queuing (NCQ). It is [[backward compatible]] with SATA 1.5&nbsp;Gbit/s.<ref name="SATA-IO website">{{cite web |url=http://www.sata-io.org/developers/naming_guidelines.asp |title=SATA-IO Specifications and Naming Conventions |website=sata-io.org |access-date=2012-08-30 |url-status=live |archive-url=https://web.archive.org/web/20120829113659/http://www.sata-io.org/developers/naming_guidelines.asp |archive-date=2012-08-29 }}</ref>

Second-generation SATA interfaces run with a native transfer rate of 3.0&nbsp;Gbit/s that, when accounted for the [[8b/10b encoding]] scheme, equals to the maximum uncoded transfer rate of 2.4&nbsp;Gbit/s (300&nbsp;MB/s). The theoretical burst throughput of the SATA revision 2.0, which is also known as the SATA 3&nbsp;Gbit/s, doubles the throughput of SATA revision 1.0.

All SATA data cables meeting the SATA spec are rated for 3.0&nbsp;Gbit/s and handle modern mechanical drives without any loss of sustained and burst data transfer performance. However, high-performance flash-based drives can exceed the SATA 3&nbsp;Gbit/s transfer rate; this is addressed with the SATA 6&nbsp;Gbit/s interoperability standard.

==== SATA revision 2.5 <span class="anchor" id="2.5"></span> ====

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">

* 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.
