SATA es una actualizaci\u00f3n del est\u00e1ndar de se\u00f1alizaci\u00f3n paralela (parallel ATA o PATA) de la d\u00e9cada de 1980 utilizado para la electr\u00f3nica de unidad integrada mejorada (EIDE) y la anterior electr\u00f3nica de unidad integrada (IDE).<\/p>\n<p>Serial ATA se introdujo en 2005. En 2010, se actualiz\u00f3 para utilizar un cable de datos con siete conductores compuestos por tres masas y cuatro l\u00edneas de datos activas de dos pares con conectores wafer en cada extremo.<\/p>\n<h2><span id=\"definicion_de_adaptador_serie_de_tecnologia_avanzada\">Definici\u00f3n de adaptador serie de tecnolog\u00eda avanzada<\/span><\/h2>\n<p>SATA ofrece varias ventajas sobre ATA y PATA. <strong>Las caracter\u00edsticas m\u00e1s destacadas son el intercambio en caliente<\/strong> y la mayor velocidad de transferencia de datos.<\/p>\n<p>El intercambio en caliente permite sustituir componentes del sistema inform\u00e1tico sin tener que apagarlo. Los sistemas antiguos ten\u00edan que apagarse antes de sustituir o instalar m\u00f3dulos del sistema. La velocidad de transferencia de datos de 6 Gbps de SATA tambi\u00e9n es mucho m\u00e1s r\u00e1pida que las de ATA y PATA.<\/p>\n<p>La interfaz est\u00e1ndar para SATA es la interfaz de controlador de host avanzado (AHCI), que i<strong>ncluye funciones innovadoras como el intercambio en caliente y la cola de comandos nativa.<\/strong> Si la placa base o el chipset no admiten AHCI, SATA funcionar\u00e1 normalmente en modo de emulaci\u00f3n IDE, que no admite funciones avanzadas.<\/p>\n<p>SATA tambi\u00e9n permite la cola de comandos nativa (NCQ). Esta tecnolog\u00eda pretende aumentar el rendimiento permitiendo que la unidad de disco duro aumente el orden en que se ejecutan los comandos de lectura\/escritura.<\/p>\n<p><strong>NCQ permite reprogramar varios comandos y permite al host enviar m\u00e1s comandos<\/strong> a la unidad de disco duro mientras busca datos para otro comando.
