Toshiba Expands 2.5-inch HDD Line With First Commercially Available
200GB-Per-Platter Product and New 7,200 RPM Family
Eco-Conscious HDDs Deliver Superior Performance and Highest Capacity for
Holiday Season Mobile PCs
IRVINE, Calif., July 15 /PRNewswire/ -- Toshiba Storage Device Division
(SDD), the pioneer in small form factor hard disk drives (HDDs), today
announced the industry's first commercially available 200GB-per-platter 5,400
RPM HDD, which will provide the highest HDD capacity at 400GB for integration
into mobile PCs for the holiday season. In addition, the company also
introduced a new family of high-end 7,200 RPM HDDs, offering up to 320GB
storage capacity and superior performance.
The standard 9.5-millimeter-high package of both HDDs fits existing
product designs, enabling an easier migration path to high-capacity storage
for portable PC, gaming and personal storage manufacturers catering to the
diversified needs of mobile users in the digital age.
In addition to increasing areal density to 308 gigabits-per-square-inch,
the 400GB MK4058GSX incorporates acoustic techniques that make the 5,400 RPM
HDD nearly inaudible during seek operations. The large storage capacity and
silent operation of the MK4058GSX are particularly suited for video and audio
playback.
For optimum user experience in data-intensive applications such as image
processing, video editing, multimedia and gaming, Toshiba's new 7,200 RPM,
MKxx54GSY series delivers first-rate performance through a combination of
factors, including optimized firmware, caching algorithms and fast data
throughput of 1,020 megabits per second.
The MKxx54GSY provides a variety of capacity options ranging from 320 to
80GB. For added durability in mobile applications, free-fall sensor options
also are available on the new HDD series.
Environmentally Conscious HDDs
Both the MK4058GSX and MKxx54GSY series reflect progress Toshiba has made
toward its corporate initiative to enhance the environmental soundness of its
products by discontinuing use of certain chemical substances and reducing
carbon dioxide emissions during HDD operation. The company ceased use of the
six substances banned by the European Union Directive on the Restriction of
the Use of Certain Hazardous Substances in Electrical and Electronic Equipment
(RoHS) in all new products developed since April 2005, achieving full
compliance with the RoHS Directive before the requirement came into effect in
July 2006.
Focus on the elimination of toxic substances in halogenated flame
retardants began in 2001 when Toshiba shipped HDDs with halogen-free printed
circuit boards. The MK4058GSX takes this initiative further by discontinuing
the usage of specified hazardous halogens and toxic chemicals such as
polyvinyl chloride (PVC), antinomy trioxide and red phosphorus across all
components incorporated in the drive.
Better Power and Temperature Performance vs. 3.5-inch HDDs
The eco-conscious MK4058GSX and MKxx54GSY also deliver lower power
consumption and cooler operation than 3.5-inch HDDs at the same capacity
points, offering PC manufacturers a solution to miniaturize designs with more
environmentally sound storage alternatives. Power consumption during read and
write operation can be reduced by as much as 70 percent over the most
power-conservative 3.5-inch HDDs with both of Toshiba's new 2.5-inch HDDs.
"These introductions up the ante in capacity and performance as Toshiba
remains focused on designing and developing innovative storage solutions to
fuel the next generation of digital products for end users," said Maciek
Brzeski, vice president of marketing at Toshiba Storage Device Division.
"Beyond building storage products that are technically excellent based on our
rich engineering heritage, we also continue to collaborate on a global basis
to bring environmentally conscious products to market."
Information and Availability
Toshiba's new 7,200 RPM 2.5-inch HDD series will begin shipping to PC
manufacturers in August, while the 400GB 5,400 RPM HDD will enter high-volume
production by September for installation in products for the holiday shopping
season. These new HDDs will be shown at the Intel Developer's Forum, August
19-21, in the Serial ATA International Organization booth. Interested

(1) One Gigabyte (1 GB) means 10 to the ninth power = 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 = 2 to
the thirtieth power = 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.
