TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO:6502) today announced the launch of the world's first[1] series of Self-Encrypting Drives (SED) equipped with Wipe Technology, Toshiba's proprietary suite of security functions that bring an unsurpassed level of data protection to IT equipment. Wipe Technology allows users to determine a range of security settings, including invalidation of encryption keys and data invalidation when a drive is removed from its housing or connected to an unauthorized host system.
The five models in the 2.5-type MK6461GSYG family range from 160 gigabytes (GB) to 640GB and are designed for use in copiers, printers, POS systems, PCs and other IT devices. Sampling will start from the end of April with mass production following at the end of June.
IT departments must contend with various security risks, from lost and stolen PC through to compliance with increasingly strict privacy laws and regulations governing data security. These concerns also go beyond PCs. Today, most office copier and printing systems utilize HDD capacity and performance to support productivity and the security of recorded document image data that must be maintained. Furthermore, data invalidation required overwriting for hours or physically disrupting until now.
Wipe Technology directly addresses these concerns. In August 2010, Toshiba announced development of the Wipe Technology that offered users two levels of control, which achieved great interest from the IT industry. Reflecting voice of customers to meet varying using conditions, MK6461GSYG family drives not only offer the latest version of Wipe Technology adding the third level of control, but also configure areas for invalidation and encryption, achieving an optimized solution for data security.
1. Invalidation of all data by the system.
This invalidates all
data. This feature is designed for use prior to system disposal or
re-purposing to ensure that private data never leaves the control of the
responsible business unit or the IT department
2. Invalidation of data on powering down
The HDD encryption key is
automatically invalidated when the drive's power supply is turned off.
If a Wipe Technology SED drive is removed from a system, it can be set
to invalidate all data on the drive.
3. Invalidation of data when the equipment is connected to an
unauthorized system (The new technology which was added this time)
When
an SED HDD is inserted into a system it triggers "challenge response[2]"
authentication to confirm the system is known to the HDD. If the
authentication fails, the HDD automatically deletes the encryption key.
This level counteracts attempts to read a drive by physically removing
it from a secure host system and installing it in another system.
Wipe Technology HDD can be incorporated into existing system architectures and integrated into various IT equipments where users demand a high level of data security, including multifunction printers, POS systems and PCs. Toshiba is now studying future integration of the technology into solid state drives (SSD).
Toshiba Group will adopt Wipe Technology SED HDD into enterprise use such as its own brand PCs, multifunction printers, and POS system, as a further advance in enhanced information security for information and communications technology.

Environmental Aspects
(1) RoHS compliant
The new drives
comply with the European Union's RoHS Directive on the restriction of
the use of six hazardous substances in electrical and electronic
equipment.
(2) Recycling storage products
The new drives lead to less
electrical power, laborsaving, and enable re-purposing storage products,
by shortening time by immediate invalidation of the data, compared to
overwriting for hours or physically disrupting, which was required until
now.

[3]One Gigabyte (1 GB) means 109 =1,000,000,000 bytes using
powers of 10. A computer operating system, however, reports storage
capacity using powers of 2 for the definition of 1 GB = 230=
1,073,741,824 bytes, and therefore shows less storage capacity.
One
Megabyte (1 MB) means 106 =1,000,000 bytes using powers of
10. A computer operating system, however, reports storage capacity using
powers of 2 for the definition of 1 MB = 220= 1,048,576
bytes, and therefore shows less storage capacity.
Available storage
capacity (including examples of various media files) will vary based on
file size, formatting, settings, software and operating system.

[5]AES 256 (256-bit Advanced Encryption Standard) is the selected encryption algorithm by the 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, and 256 bits. The longer the key, the stronger the encryption.
