The hard disk using SATA (Serial ATA) port is also called serial port hard disk, which is the trend of PC hard disk in the future.
In 2001, the Serial ATA Committee consisting of Intel, APT, Dell, IBM, Seagate and Maxtor officially established the Serial ATA 1.0 specification.
In 2002, although Serial ATA related equipment was not officially launched, Serial ATA committee has pre-empted the Serial ATA 2.0 specification.
Serial ATA adopts serial connection mode. Serial ATA bus uses embedded clock signal and has stronger error correction capability. Compared with the past, the biggest difference is that it can check the transmission command (not just data). The error is automatically corrected, which greatly improves the reliability of data transmission. The serial interface also has the advantages of simple structure and hot swap support.
Serial hard disk is a new type of hard disk interface that is completely different from parallel ATA. It is well known for transmitting data in serial mode. Compared to parallel ATA, it has a lot of advantages. First, Serial ATA transfers data in a serial serial fashion, transferring only 1 bit of data at a time. This can reduce the number of pins on the SATA interface, making the number of connecting cables less and more efficient.
