ASUS A55VM series currently provides eSATA interfaces on many desktop motherboards and laptops. eSATA is actually the external SATA specification and an extension of the industry standard interface Serial ATA (SATA). Note that eSATA is just an extended SATA interface and is used to connect external rather than internal SATA devices. Simply put, eSATA technology is used to allow external I/O interfaces to use SATA functions. For example, with an eSATA interface, you can easily connect a SATA hard drive to the eSATA interface through an adapter without having to open the chassis to replace the SATA hard drive.

At present, many ASUS notebooks have eSATA interfaces, such as: F8Tr, F80Q, G70Sg/ G, M50Vn/Vc/Vm, etc. For notebook products, whether the eSATA interface is compatible with USB can be checked through the NB-Spec in the Call Center 800 Table.

Corresponding to SATA I (1.5Gb). /s) and SATA II (3Gb/s), eSATA is also divided into eSATA I (1.5Gb/s) and eSATA II (3Gb/s)
