-400GB Drive Cuts Acoustic Noise During Data Seek By 2dB(1) For
near Silent Operation-
TOKYO--(Business Wire)--
Toshiba Corporation (TOKYO:6502) today announced a new line-up of
high performance 2.5-inch HDDs, including a low-noise flagship model
that boosts areal density to 477Mbit/mm2 (308Gbpsi) to achieve a
capacity of 400GB on just two platters, plus five drives that bring
new levels of performance and 7,200rpm rotational speeds to the
company's full range of storage capacities.
Mass production of the 400GB MK4058GSX will start from September,
targeting notebook PC and consumer electronic applications. Mass
production of the 7,200rpm drives will start in August. The line-up
includes the 320GB MK3254GSY and models with 80, 120, 160 and 250GB
capacities.
Toshiba will feature the new drives at DISKCON JAPAN 2008,
organized by The International Disk Drive Equipment and Materials
Association (IDEMA), which will be held in Tokyo, Japan, from July 22
to 23, and at IFA 2008, one of the world's largest consumer
electronics trade fairs, which will be held in Berlin, Germany, from
August 29 to September 3.
The MK4058GSX uses an improved read-write head and enhanced
magnetic layer to boost areal density to 477Mbit/mm2 and achieve a
capacity of 400GB on only two platters, the highest data density of
any of Toshiba's 2.5-inch HDD. A further plus is that acoustic noise
during data seek has been reduced by 2 decibels (dB), compared to the
company's current top-of-the-line 320GB MK3252GSX, making operation
almost inaudible. As a result, the new 400GB drive is ideally suited
for noise-free playback of movies and music on notebook PCs and
digital products. These advances are complemented by an improved
energy consumption efficiency(2) that makes the MK4058GSX
approximately 20% more efficient than Toshiba's current
top-of-the-line MK3252GSX.
The five other drives that Toshiba has added to its line-up take
full advantage of a 7,200rpm rotation speed to boost performance.
Compared to the current 200GB model (MK2049GSY), the 320GB MK3254GSY
improves maximum internal data transfers rate by approximately 14% to
support high-speed processing of high volume data, meeting demand for
notebook and desktop PCs offering faster performance. The 320GB drives
is also 37% more efficient than the MK2049GSY in terms of energy
consumption efficiency(2). All of the drives, available in a line-up
of 80, 120, 160, 250 and 320GB capacities, support an optional Free
Fall Sensor function, that detects a falling HDD and parks the head
before impact.
All the new drives comply with the European Union's RoHS
directive(3) for eliminating use of six hazardous substances in
electrical and electronic equipment, and the MK4058GSX is Toshiba's
first halogen-free(4) 2.5-inch HDD.
Toshiba Group, a Corporate Citizen of the Planet Earth, is
committed to realizing a better environment. Guided by "Toshiba Group
Environmental Vision 2050" the Group is implementing measures to boost
environmental efficiency by 10 times in FY2050, against the benchmark
of FY2000. The core target is to reduce projected CO2 emissions by a
total equivalent to 117.7 million tons a year by FY2025, through the
development and sales of highly efficient power supply equipment and
systems, and the manufacture of environmentally conscious home
appliances and office equipment. By working to mitigate global
warming, make efficient use of resources and control management of
chemicals, Toshiba Group creates value for people and promotes
lifestyles in harmony with the Earth.
Background
2.5-inch hard disk drives are now found in many and diverse
applications, from desktop and mobile PCs to other digital consumer
products. The market has a voracious appetite for larger data
capacities, as more powerful networks and applications bring
audio-visual capabilities to more products. Toshiba will sustain the
industry's ability to meet customer needs by providing cutting-edge
technologies that add to areal density, operating speed and overall
drive performance.
Key Features of New Products
MK4058GSX
1. Achieving areal density of 477Mbit/mm2 (308Gbspi).
MK4058GSX achieves an areal density of 477Mbit/mm2, by the result
of improving the read-write head and of an enhanced magnetic layer.
With the same two platter design as Toshiba's current 320GB design,
the new model offers a 400GB capacity, the largest yet achieved, while
retaining the 9.5mm thickness of its predecessor.
2. 2dB acoustic noise reduction in data seek.
Toshiba has directed its latest advances in HDD technology to
reduce noise by 2dB, suppressing it to a level where users can
playback movies and music without any noise distraction during data
seek.
3. Improved energy consumption efficiency.
Compared to the 320GB MK3252GSX, the new MK4058GSX improves energy
consumption efficiency, as defined under the Japanese legal standard,
to 0.0015W/GB, a 20% improvement.
4. Environmentally conscious products
(1) Halogen Free Product
The MK4058GSX is Toshiba's first 2.5-inch HDD that achieve
chlorine and bromine concentrations below the standard required for
recognition as a Toshiba environmentally conscious products, an ECP
(below 900ppm for each, and an overall total below 1,500ppm).
(2) Lower CO2 emissions during the product lifecycle
During their lifecycle, the new drives will lower CO2 emissions by
approximately 95g a year(5).
(3) RoHS compatible
The new drive complies with the European Union's RoHS directive
for eliminating use of six hazardous substances in electrical and
electronic equipment.
(4) MK4058GSX meets standards for certification as a standout
