Encryption Algorithm

Wipe technology
[1] AES 256 (256-bit Advanced Encryption Standard) is the selected encryption algorithm by U.S. National
Institute of Standards and Technology. This is the standard form of encryption used by the U.S. government.
AES defines three possible key lengths; 128, 192, 256 bits. The longer the key, the stronger the encryption.
*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.
*Wipe technology: Toshiba's unique technology which automatically erases data when an HDD is accessed by
an unregistered system.
