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