Hitachi Endurastar J4K20 and N4K20 hard
disk drives
The industry's first and only hard drives built to perform in
extreme temperature environments
Highlights:
- 20GB capacity
- Operating temperature range from -20° C to +85° C
- Fly height compensation accommodates changes in air density
caused by temperature and altitude
- Built-in shock sensor enhances data integrity in automotive
applications
- Enhanced moisture control system ensures corrosion control in
extreme environments
Practical Innovation
Hitachi presents a 2.5-inch hard disk
drive designed specifically to perform
in extreme temperature environments.
Offered at 20GB capacities, the new
Endurastar J4K20 and Endurastar N4K20
create a new generation of hard drives to
meet the expanding needs of emerging
markets.
Ideal for Automotive Applications
Built to operate in temperature ranges
of up to -20° C to +85° C, the Hitachi
Endurastar hard disk drives are the only
drives available in the market today
which support the environmental conditions
commonly found in the automotive
industry.
These drives are the ideal choice for
automotive applications, including car
navigation and car audio products.
Performance and Reliability
The new Endurastar models feature glass
media and load/unload technology in
addition to shock sensor technology,
which cushions the drive in less than ideal
shock or vibration conditions.
The J4K20 and N4K20 incorporate fluid
dynamic bearings (FDB) in the spindle
motor, re-designed to support a wider temperature
range. The new FDB allows the
same quiet operation and improved shock
characteristics as with PC models, but
offers even higher reliability for automotive
environments.
