Fujitsu has announced Full Disk Encryption (FDE) for their 2.5-inch SATA drives (7200-rpm 3.0Gb/s Serial ATA), boasting storage space of up to 320GB. The announcement means that these drives are the largest, and most secure, for data at rest.

Fujitsu's hardware-based encryption helps ensure that data on a lost or stolen machine can't be compromised. The MHZ2 CJ series is the first in the world to support hardware-based 256-bit AES security. Current software-based security offerings seen today have a few weaknesses. For example, one flaw is that the keys used to secure the data on the drive are stored in memory, thus they are subject to cold boot types of attack. In addition, the encryption itself is CPU intensive, which affects system performance.
In the MHZ2 CJ series, Fujitsu says that encryption and decryption are performed by the hardware of the drive instead of by the computer's CPU and memory. The key used to encrypt and decrypt data is cryptographically regenerated only when the correct password is received at power-on, and is unattainable when the system is powered off.
Attacks to the drive or computer when the device is in hibernate or sleep mode, as seen in alternate cold boot attacks, are also rendered useless as the drive automatically encrypts and decrypts the data. As data is saved to the drive, it is instantly secured, with zero impact to the CPU or memory.
Another secure feature deals with data removal, and disposal. The advanced secure erase feature immediately invalidates every piece of data just by changing the in-drive encryption key, making the stored data indecipherable. The entire disk is erased in a matter of seconds.
The drive is also available in 80GB, 120GB, 160GB, and 250GB capacities and is expected at the end of May.
