What is the sata interface connected to?

The SATA interface is connected to the motherboard and a large number of storage devices. SATA is the abbreviation of Serial ATA, which is a computer bus; the SATA bus uses an embedded clock signal and has stronger correction capabilities. Error capability, if an error is found, it will be automatically corrected, which greatly improves the reliability of data transmission.

The SATA interface is used to connect the motherboard and a large number of storage devices.

SATA is the abbreviation of Serial ATA, that is, Serial ATA. It is a computer bus whose main function is to transmit data between the motherboard and a large number of storage devices (such as hard drives and optical disk drives). This is a new type of hard disk interface that is completely different from parallel PATA. It is named because it uses serial mode to transmit data. The SATA bus uses an embedded clock signal and has stronger error correction capabilities. Compared with the past, its biggest difference is that it can check the transmission instructions (not just data). If errors are found, they will be automatically corrected. This is very important. The reliability of data transmission is improved to a certain extent. The serial interface also has the advantages of simple structure and support for hot swapping.

Developed by the "Serial ATA Working Group" in November 2000, SATA has completely replaced the old hard drive with the old PATA (Parallel ATA or formerly known as IDE) interface. It is named after its use of serial data transmission. In terms of data transmission, SATA is faster than ever and supports hot swapping, allowing hardware to be plugged in or out while the computer is running. On the other hand, the SATA bus uses an embedded clock frequency signal, which has stronger error correction capabilities than before. It can check the transmission instructions (not just data). If errors are found, they will be automatically corrected, improving the reliability of data transmission. sex. However, the most obvious difference between SATA and the past is the use of thinner cables, which facilitates air circulation inside the chassis and increases the stability of the entire platform to a certain extent.

Currently, SATA has three specifications: SATA 1.5Gbit/s, SATA 3Gbit/s and SATA 6Gbit/s. There will be faster SATA Express specifications in the future.
