SATA is an abbreviation of Serial ATA. This is completely different from parallel ATA novel hard disk interface type. It is named of using the serial way to transmit data. SATA bus uses embedded clock signal, with a stronger capability of correcting error. The biggest difference compared with the previous lies in its ability to check the transmission instructions (not just data). If finding an error, it will be automatically corrected, to greatly extent, which improves the reliability of data transmission. The serial interface also has a simple structure, the advantages of hot-swappable.
