The eSATA external hard disk can be connected to the SATA interface of the motherboard by using the eSATA to SATA adapter cable. The eSATA standard is an external version of the SATA standard. The definition of its line pin is exactly the same as that of the SATA standard. The difference between the two standards is mainly due to the different interface shapes.The shape of the eSATA interface is a flat "I" shape, while the shape of the SATA interface is an "L" shape with corners, so the two interfaces cannot be directly inserted into each other.The eSATA to SATA adapter cable can be used to convert the shape of the interface, and the eSATA external hard disk can be connected to the SATA interface for use.
It is connected to the Internet cable.You can't use the telephone line directly. If you use ADSL broadband, Telecom will give you MODE and make a crystal head
The full name of eSATA is External Serial ATA.That is, external serial ATA. See, it is the external extension specification of 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, if the motherboard has an eSATA interface, you can easily connect the SATA hard disk to the eSATA interface of the motherboard without opening the chassis to replace the SATA hard disk.
Compared with SATA interface, eSATA has some changes in hardware specifications. Metal spring pieces are added at the connection of the data cable interface to ensure the firmness of the physical connection.The original SATA uses an L-shaped plug to distinguish the interface direction, while eSATA uses different thicknesses and grooves at the upper and lower ends of the plug to prevent mis insertion. It also supports hot plug.Although the interface mode has been changed, the underlying physical specifications of eSATA have not changed, and the 7-pin data cable is still used, so only changing the interface can achieve compatibility with SATA devices.However, eSATA only provides data interface and lacks power supply
