Serial Attached SCSI and Serial ATA Seek Their Levels

摘要

Serial Attached SCSI (SAS) and Serial ATA (SATA) are two important technologies emerging in the market after years of positioning, and are seemingly poised for market success. We appear to be at a point in time where the cards are falling into place for both I/O technologies. This article will explore the capabilities of SAS and SATA, first as complementary interconnect schemes and secondly as high-volume storage devices. The article will also attempt to cut through some of the rhetoric surrounding both interfaces and draw some honest conclusions about where and how these important technologies will coexist within the mainstream storage markets.
