SATA connector is a necessary component for connecting storage devices (such as hard disk, optical drive, etc.) and motherboard. Its full name is Serial ATA, which is an interface standard for data transmission. SATA connector adopts serial transmission mode, which can greatly improve the data transmission rate and reduce the number of cables. It has the characteristics of simple structure, high transmission efficiency and small size, and has gradually replaced the old parallel ATA(PATA) connector.

SATA connector is L-shaped. Unlike PATA connector, SATA connector has only seven metal contacts, four of which are data transmission channels (TX, RX, GND, GND), two are power channels (+5V, +12V), and one is signal ground (SG) for signal transmission. The plug size is 1.27mm, which has good anti-insertion, anti-vibration, anti-drop and other functions, and can ensure the safety and stability of the connection.

SATA connectors are widely used, including desktops, laptops, servers and so on. SATA connectors can not only connect storage devices such as hard disks and CD-ROMs, but also be widely used in storage controllers such as solid-state hard disks and RAID cards. The high-speed transmission characteristics of SATA connector make it an indispensable part of modern storage system, which can meet the storage needs of different fields and different performance requirements.

In a word, SATA connector, as an important interface for data transmission, has the characteristics of simple structure, high transmission efficiency and small size, which makes it widely used. With the continuous development of computer technology, SATA connectors are constantly upgraded and improved, and will continue to be an important part of storage systems.
