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

drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary. 2.9 Environmental specifications 2.9.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions for standard models. Recommended measur
