Toshiba MKxx61GSYG Series Self-Encrypting Hard Drives

Toshiba announced its first family of self-encrypting hard disk drives, the MKxx61GSYG Series with the Wipe Technology, which 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 2.5-inch MKxx61GSYG series is available in 160GB, 250GB, 320GB, 500GB and 640GB capacities. These Self-Encrypting Drives (SED) use SATA 3Gbps interface and offers 16MB buffer memory and 7200RPM rotational speed. They feature AES 256-bit encryption.

Toshiba will start mass production of the MKxx61GSYG series SED in Q2.

Three level of control of the Wipe Technology:

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.
