SATA is the abbreviation for Serial ATA, Serial ATA. This is a new type of hard disk interface that is completely different from parallel ATA, and is named because it transmits data in a serial way. SATA bus using embedded clock signal, with a stronger ability to error correction, compared with the past, the biggest difference is that the transmission instruction

Technology Attachment (ATA ). when the IDE standard was first introduced, many motherboards required separate controller cards to interface with IDE devices.
Almost all modern motherboards have two on-board ide ports, with each port being able to control two ide devices, for a total of four. if you want to add more than four ide devices, you must install an additional controller card such as the one shown in Figure. IDE ports have 39 or 40 pins and
