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. � 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 from parallel ATA easy by providing legacy software support. Serial ATA w

2.8.1.1 Typical current profiles Figure 1. Typical 5V startup and operation current profile Figure 2. Typical 12V startup and operation current profile 2.8.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line. � Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10 MHz
