The MHZ2 CJ Series from Fujitsu are 2.5 inch drives targeted to notebook/laptop deployments and are served in capacities of 80 to 320 GB.

The key feature of the drives is their support for built-in FDE (Full Disk Encryption), where the whole contents of the drive are encrypted/decrypted automatically via on-board hardware. The vendor states that the necessary key for the encryption of the data remains in the drive itself after boot up, and is regenerated when the correct password is received at system startup (and is therefore unattainable when the system is powered off). In brief, the password is requested by the BIOS before the OS boots up, which is then transferred to the drive using the ATA security command set. After OS boot, the password is no longer in system memory; and the vendor further notes that it's not possible to access the disk drive's CPU memory via the SATA interface and the drive firmware cannot be changed without cryptographic authentication. The encryption itself is 256-bit AES. Because the encryption/decryption itself takes place within the drive, the vendor notes that there is no impact to overall system performance.

Related to the drive's encryption capabilities is a Secure Erase feature, which enables the full contents of the drive to be made immediately inaccessible by changing the in-drive encryption key.

The drives themselves are SATA drives with a 3.0 Gb/sec interface and spin at 7200 RPM. Offered in capacities ranging from 80 to 320 GB, average seek times are 10.5 ms/12.5 ms (read/write), with a maximum seek time listed at 20.5 ms. A 16 MB buffer and 3 year limited warranty rounds out the drive's feature set.
