                        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 normally necessary to set  any jumpers 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 tran

                        2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.  Actual drive case temperature should not exceed 70°C (158°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet.
