about SATA | Serial ATA

Serial ATA (ATA: serial serial advanced technology attachment) is a computer bus and is responsible for the board and mass storage devices such as hard drives and optical drive) to transfer data between the mainly used for PCS. Serial ATA and Serial SCSI (SAS:serial attached SCSI) for both cable compatible with SATA hard drives can be connected to a SAS interface. The respective 1.5gbit/s SATA SERIAL ATA, SATA, 3gbit/s and 6gbit/s three SATA specification. Device compatibility and both can use similar cable. Sas is a point-to-point (point-to-point) and allows multiple ports on a single controller, it can be integrated on the system board (mother board); can also be added. The technology is built on a robust parallel SCSI communication technologies.
Sata port to use (English: port multiplier), also known port multiplier that allows multiple SATA devices connect to one SATA primary port. Many conventional controller does not support this feature, because this is not the SATA controller is required. The multiplexer server port (port multiplier) has the following benefits: Reduce the number of wires supported number of SATA devices do not need to add additional SATA controller.
