Description

eSATA connector plug and its socket

【Technical field】

【Background technique】

With the increasing development of electronic technology, portable electronic devices are more and more widely used by consumers. The demand for massive data transmission further prompts the corresponding interface connectors to support massive data transmission, thus SATA (Serial Advanced Technology Attachment: Serial Advanced Technology Attachment) technology appears. But in the mainstream market, SATA has never been involved in the mobile storage market. Most computer systems and retail motherboards do not have a standard external SATA interface; and because the SATA cable can only be plugged and unplugged dozens of times, in this case, eSATA technology came into being. The full name of eSATA is External Serial ATA (External Serial Advanced Technology Attachment), which is an external extension specification of the SATA interface. In other words, eSATA is the "external" version of SATA, which is used to connect external rather than internal SATA devices. For example, with the eSATA interface, you can easily connect the SATA hard disk to the eSATA interface of the motherboard without opening the case to replace the SATA hard disk. Compared with the SATA interface, eSATA has some changes in hardware specifications, and a metal shrapnel is installed at the connection of the data cable interface to ensure the firmness of the physical connection. eSATA also supports hot plugging. The 7-pin data cable is still used, so it only needs to change the interface to achieve compatibility with SATA devices.

Although eSATA has outstanding advantages in use, there are also some shortcomings. eSATA only provides data interfaces and lacks power supply, that is, devices based on eSATA interfaces must use additional configuration power supplies, and if users hot-plug data The sequence of plugging and unplugging the power cord and power cord is wrong, resulting in the failure of the hot-swapping function and making it unusable, or even affecting the performance of eSATA.
