Automatic hardware based encryption

HDDs with 320Gbyte capacity and the industry's highest rotational speed of 7200rpm will carry automatic hardware-based encryption to provide data security against theft or loss, according to Fujitsu Ltd, which is set to make the 2.5-inch HDDs available by the end of May.

The MHZ2 CJ series also offer a 3Gbit/s Serial ATA interface, and are geared for computers and external storage devices.

AES implementation
This series is the first HDD to support the 256bit Advanced Encryption Standard (AES). The drive implements the AES hardware encryption directly into the processor of the HDD, resulting in more robust security and faster system performance than software-based encryption.

All data stored on the HDD can be erased in less than a second using the advanced secure erase feature. For public institutions and companies that handle large amounts of personal and other confidential data, this dramatically lowers the time and cost involved in wiping clean the hard drives of computers that are disposed of or reused.

The built-in AES automatically encrypts all data when storing it on the hard disk drive and decrypts the data when read. Unlike software-based encryption, the key does not reside in the computer's memory. This makes it more resistant to attack and imposes no processing overhead on the CPU, optimizing system performance.

Moreover, with growing awareness of the problem of data stored on the hard drives of computers, anyone planning to discard or reuse a computer has been obliged to use specialized software to overwrite all the user accessible data blocks on the hard drive multiple times, a costly and time-consuming proposition. This new series of drives includes an advanced secure erase feature to dramatically reduce the total cost of ownership to public institutions as well as private enterprises.

Fujitsu is an active member of the Trusted Computing Group, an organization that promulgates and disseminates standards for security-related technology.
