*Definition of Capacity: TOSHIBA defines a megabyte(MB) as 1,000,000bytes, a gigabyte(GB) as
1,000,000,000 bytes, and a terabyte(TB) as 1,000,000,000,000bytes.
*Energy Consumption Efficiency: Energy consumption efficiency is calculated based on power
consumption divided by formatted capacity, as defined by Japanese law.
