How is Serial Attached SCSI complementary to Serial ATA?
SAS complements SATA by adding dual porting, full duplex and device addressing, plus it offers higher reliability, performance and data availability services, as well as logical SCSI compatibility. STA will continue to enhance these metrics as the specification evolves, including increased device support and longer cabling distances. Most importantly, SAS and SATA are complementary technologies based on a universal interconnect, where SAS customers can choose to deploy cost-effective SATA drives in a SAS storage environment.
