Its full-duplex signal transmission supports 3.0Gb/s. Using SAS, multiple devices (up to 128) will be enable to connect simultaneously with thinner and longer cables, confirming its superiority over the traditional SCSI.

SATA (Serial Advanced Technology Attachment) SATA or serial ATA is a standard hard disk interface invented to replace the parallel ATA (PATA). Since in parallel transmission, several bits are sent at the same time, it seems this method is better than serial transmission in terms of speed, but noise problem occurs in parallel transmission.
