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

2.7 Power specifications The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 20. 2.7.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operat
