Toshiba Announces 1.8-Inch HDD Family With Industry-Leading 240GB Capacity for Portable Media Players, Camcorders and Ultra-Mobile PCs
IRVINE, Calif., Sept. 9 /PRNewswire/ -- Toshiba Storage Device Division
(SDD), the pioneer in small form factor hard disk drives (HDDs), today
announced the world's first dual-platter 240GB(1) (MK2431GAH) and
single-platter 120GB (MKxx31GAL series) 1.8-inch HDDs for integration into
portable media players, camcorders and compact ultra-mobile PCs for the
holiday shopping season.
The new MKxx31GAL series also includes an 80GB capacity offering, rounding
out the most complete line of high-capacity 4,200 RPM 1.8-inch HDDs for
consumer electronics (CE) and mobile PC system manufacturers.
Toshiba's two new Parallel ATA HDD families feature the industry's highest
areal density at 344 gigabits-per-square-inch, using fourth-generation
perpendicular magnetic recording (PMR) technology, which was first introduced
and commercialized by Toshiba in 2005. Toshiba's technology leadership in PMR
has enabled the company to consistently deliver leading-edge capacities in the
1.8-inch form factor to support growing demand for the miniaturization of
mobile devices to run digital video, photo, audio and computing applications.
The new 1.8-inch HDD series uses a new mechanical and firmware design for
enhanced durability, making the 80GB and 120GB single-platter HDDs well-suited
for slim-line mobile gadgets and PC applications. The new dual-platter 240GB
MK2431GAH product is especially suitable for light-weight mobile PC
applications and high-end digital video camcorders, which require high
capacity and ruggedness to protect users' valuable digital assets.
Striking Balance Between Performance and Energy Consumption
Design elements incorporated in the 240GB MK2431GAH optimize power
performance to new levels with a 33 percent overall improvement in energy
consumption efficiency(2) over Toshiba's previous generation two-platter,
160GB 3,600 RPM 1.8-inch model. In addition, Toshiba's entire line of new
4,200 RPM 1.8-inch HDDs delivers solid performance while state-of-the-art
electrical components reduce power consumption during read and write
operations by 20 percent, resulting in a cumulative improvement in power
management. In addition, PC applications benefit from the performance boost
of an 8MB buffer.
"Toshiba's dedication and focus on 1.8-inch HDD product development over
the past decade has enabled us to continually drive innovation in this form
factor -- from robust capacity introductions to improved performance and power
efficiency," said Maciek Brzeski, vice president of marketing at Toshiba
Storage Device Division. "Thanks to these continual advancements, 1.8-inch
HDDs have become an ideal form factor for the digital world, where the ability
to handle rich digital content in a mobile environment is king."
Toshiba has been the market share leader in the 1.8-inch HDD category
since its first product was introduced in 2000 and has cumulatively shipped
more than 60 million 1.8-inch HDDs worldwide. The company's new 1.8-inch HDDs
also reflect a commitment to enhancing the environmental soundness of its
products by discontinuing use of certain environmentally harmful chemical
substances across all components incorporated in the drive and reducing carbon
dioxide emissions during HDD operation. In particular, the MKxx31GAL series
has been designed to lower carbon dioxide emissions by 54 grams per year.(3)
Toshiba's new 1.8-inch HDDs will be incorporated into CE and mobile PC
products shipping this holiday season. Interested developers and design

(1) One Gigabyte (1 GB) means 109 = 1,000,000,000 bytes using powers
of 10. A computer operating system, however, reports storage capacity using
powers of 2 for the definition of 1 GB = 230 = 1,073,741,824 bytes, and
therefore shows less storage capacity. Available storage capacity will also be
less if the computer includes one or more pre-installed operating systems,
pre-installed software applications or media content. Actual formatted
capacity may vary.
(2) Energy consumption efficiency is calculated based on power consumption
divided by formatted capacity, as defined by Japanese law.
(3) Comparison against Toshiba's one-platter, MK6015MAP model, which
generates 887 grams per year in carbon dioxide emissions and is used as the
established baseline for carbon dioxide emission measurements on the company's
1.8-inch products.
