SATA was announced in 2000<ref>"Seagate, APT and Vitesse Unveil the First Serial ATA Disc Drive at Intel Developer Forum", Seagate Technology, Aug. 22, 2000</ref><ref>{{cite web |last1=Andrawes |first1=Mike |title=Intel IDF Report #2 - Serial ATA & USB 2.0 |url=https://www.anandtech.com/show/484 |website=AnadTech |publisher=Future plc |access-date=30 August 2020}}</ref> in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native [[hot swapping]], faster [[data transfer]] through higher signaling rates, and more efficient transfer through an (optional) [[I/O]] queuing protocol. [[#1.0|Revision 1.0]] of the specification was released in January 2003.<ref name="SATA1a" />

Serial ATA industry compatibility specifications originate from the [[Serial ATA International Organization]] (SATA-IO). The SATA-IO group collaboratively creates, reviews, ratifies, and publishes the interoperability specifications, the test cases and [[plugfest]]s. As with many other industry compatibility standards, the SATA content ownership is transferred to other industry bodies: primarily INCITS T13<ref name="INCITS_T13" /> and an INCITS [[T10 subcommittee]] ([[SCSI]]), a subgroup of T10 responsible for [[Serial Attached SCSI]] (SAS). The remainder of this article strives to use the SATA-IO terminology and specifications.

Before SATA's introduction in 2000, PATA was simply known as ATA. The "AT Attachment" (ATA) name originated after the 1984 release of the [[IBM Personal Computer/AT|IBM Personal Computer AT]], more commonly known as the IBM AT.<ref>{{cite web|url=https://ecse.rpi.edu/courses/S15/ECSE-4780/Labs/IDE/IDE_SPEC.PDF|title=Lamars, Lawrence J., ''Information technology - AT Attachment Interface for Disk Drives'', Computer and Business Equipment Manufacturers Association, 1994, xi (introduction)|access-date=2016-08-02|url-status=live|archive-url=https://web.archive.org/web/20160617193535/https://ecse.rpi.edu/courses/S15/ECSE-4780/Labs/IDE/IDE_SPEC.PDF|archive-date=2016-06-17}}</ref> The IBM AT's controller interface became a de facto industry interface for the inclusion of hard disks. "AT" was IBM's abbreviation for "Advanced Technology"; thus, many companies and organizations indicate SATA is an abbreviation of "Serial Advanced Technology Attachment". However, the ATA specifications simply use the name "AT Attachment", to avoid possible trademark issues with IBM.<ref>{{cite book |url=https://books.google.com/books?id=Hyl8SA1eHzIC&q=AT+&pg=PA105|title= Govindarajalu, B., ''IBM PC And Clones: Hardware, Troubleshooting And Maintenance''|publisher=Tata McGraw-Hill Publishing Company|date=2002|page=xxxi |isbn= 9780070483118|access-date=2016-08-02}}</ref>

SATA host adapters and devices communicate via a high-speed [[serial communications|serial]] cable over two pairs of conductors. In contrast, parallel ATA (the [[retronym|redesignation]] for the legacy ATA specifications) uses a 16-bit wide data bus with many additional support and control signals, all operating at a much lower frequency. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and [[ATA Packet Interface|ATAPI]] command sets as legacy ATA devices.

The world's first SATA hard disk drive is the Seagate Barracuda SATA V, which was released in January 2003.<ref>{{cite web|url=https://www.seagate.com/support/disc/manuals/sata/cuda5_sata_pm.pdf|access-date=2023-08-17|title=Barracuda Serial ATA V Family}}</ref>

SATA has replaced parallel ATA in consumer desktop and laptop [[computer]]s; SATA's market share in the desktop PC market was 99% in 2008.<ref name="rev30">{{cite web|url=http://www.serialata.org/documents/SATA-Rev-30-Presentation.pdf|title=Serial ATA: Meeting Storage Needs Today and Tomorrow|website=serialata.org|access-date=2011-10-30|url-status=dead|archive-url=https://web.archive.org/web/20120417133358/http://www.serialata.org/documents/SATA-Rev-30-Presentation.pdf|archive-date=2012-04-17}}</ref> PATA has mostly been replaced by SATA for any use; with PATA in declining use in industrial and embedded applications that use [[CompactFlash]] (CF) storage, which was designed around the legacy PATA standard. A 2008 standard, [[CFast]], to replace CompactFlash is based on SATA.<ref>{{cite web|url=https://www.engadget.com/2008/02/25/cfast-compactflash-cards-now-said-to-be-coming-in-18-to-24-mont/|author=Donald Melanson|publisher=[[Engadget]]|title=CFast CompactFlash cards now said to be coming in "18 to 24 months"|date=2008-02-25|access-date=2009-03-19|url-status=live|archive-url=https://web.archive.org/web/20090303144033/http://www.engadget.com/2008/02/25/cfast-compactflash-cards-now-said-to-be-coming-in-18-to-24-mont|archive-date=2009-03-03}}</ref><ref>{{cite web|url=http://www.dpreview.com/news/2009/1/9/preteccfaststoragecards|publisher=[[DPReview]]|title=Pretec release CFast card with SATA interface|date=8 January 2009|access-date=19 March 2009|url-status=live|archive-url=https://web.archive.org/web/20121025074641/http://www.dpreview.com/news/2009/1/9/preteccfaststoragecards|archive-date=25 October 2012}}</ref>
