[1] Energy Consumption Efficiency: Energy consumption efficiency is calculated based on power consumption divided by formatted capacity, as defined by Japanese law.
[2] Reference: Based on the evaluation method of the International Civil Aviation Organization. Variation can occur depending on such condition as temperature and other factor.
[3] Reference: It depends on the Chronological Sciencetific Table. It is different depending on the condition of the temperature etc.
[4] Cannot be applied for high operating ratio system kind of the business-critical.
*Definition of Capacity: TOSHIBA defines a megabyte(MB) as 1,000,000bytes, and a gigabyte(GB) as 1,000,000,000 bytes.
