Fujitsu Limited and Hitachi Global Storage Technologies have both announced today their latest 500GB 2.5" hard disk drive (HDD) products featuring low power consumption and built-in encryption functions.
Fujitsu MJA2 BH and MJA2 CH series
Fujitsu has developed two new 500 GB 2.5" hard disk drive (HDD) models that
feature a rotational speed of 5,400 RPM. The MJA2 BH series will be
available from the end of December 2008, and the MJA2 CH series will be
available in the first quarter of the 2009 calendar year.
The new models consume only 1.4W of power when recording data, one-third
less than previous models. Moreover, these are Fujitsu's first halogen-free
HDD models, making them an environmentally friendly products across their
lifecycle, from deployment to disposal.
In addition, the MJA2 CH series is equipped with 256-bit Advanced Encryption
Standard (AES) encryption.
By increasing recording density, the new models deliver a maximum of 500 GB
in storage capacity. To prevent data leaks for customers handling sensitive
information, the MJA2 CH model has a built-in encryption function. This
model automatically encrypts data as it is recorded, and all data stored on
the HDD can be erased instantly, in less than a second, using the advanced
secure erase feature.
Both MJA2 BH and MJA2 CH series target the expanding notebook PC market but
also other markets such as desktop PCs.

Hitachi Travelstar 5K500.B
Hitachi Hitachi GST introduced the Travelstar 5K500.B, a mobile hard drive
that also combines advanced data encryption technology with eco-friendly
The Travelstar 5K500.B, Hitachi?s second 500GB mobile drive, uses the latest
250GB-per-platter technology to deliver a half terabyte (500GB) of capacity
in a standard 9.5mm mobile form factor.
The Travelstar 5K500.B features optional Bulk Data Encryption (BDE) for
hard-drive-level data security. The drive also meets the forthcoming Storage
Security specification established by the Trusted Computing Group (TCG), an
organization focused on developing open industry standards for security
hardware and software. The TCG Storage Security specification, targeting
consumer and commercial applications, is intended to discourage HDD/system
theft, as well as prevent data access after HDD/system disposal.
BDE encrypts data using a private security key as it is written to the disk
and then decrypts it with the key as it is retrieved. The TCG Storage
Security specification implemented in the Travelstar 5K500.B supports
pre-boot authentication in hardware, and up to four separate encrypted data
ranges with multiple user and administrative authentication credentials. It
also speeds and simplifies the drive re-deployment process. By deleting the
encryption key, the data is rendered unreadable, thereby eliminating the
need for time-consuming data-overwrite.
The Travelstar 5K500.B also features a read/write power specification of
1.4W, resulting in more energy-efficient notebooks that run cooler and have
longer battery life.
The Travelstar 5K500.B operates at 5400 RPM and is available in capacities
ranging from 120GB to 500GB.
Hitachi will also offer an enhanced-availability (EA) version of the drive,
called the Travelstar E5K500.B, which is designed for applications requiring
24x7 operation in lower transaction environments.
The Travelstar 5K500.B will be shipping worldwide in December. The
Travelstar E5K500.B will be available by the end of the first quarter, 2009.
