1.1 About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: � Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jump- ers or other configuration options. � Thinner and more flexible cabling for improved enclosure airflow and ease of installation. � Scalability to higher performance levels. In addition, Serial ATA makes the transition f
