Turn up the Heat
Hitachi delivers a 50-percent storage
capacity increase in its line of “extreme”
hard disk drives. The Endurstar J4K30
and Endurastar N4K30 are both offered
in capacities of up to 30GB, and are
designed specifically to perform in
extreme temperature environments. With
an operating temperature range as wide
as -20°C to +85°C, the new Endurastar
models are built to perform in the harshest
environments—from the desert heat to the
Antarctic chill.

Ideal for Automotive Applications
Endurastar hard drives are the preferred solution for automotive applications or other
environments which require high robustness and wider operating temperatures than
standard hard drive applications. In fact, the Endurastar J4K30 is already being used in
car entertainment and navigation applications—and 30GBs of storage means users can
store more than 5,000 audio files, four hours of MPEG2 video and enough navigation
data to cover the entire planet!

Reliability and Performance
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. Endurastar drives incorporate fluid dynamic bearings (FDB) in the spindle
motor, allowing the same quiet operations and improved shock characteristics as with
PC models, but offers even higher reliability for automotive environments. These features
enable the Endurastar drives to employ a non-operating shock tolerance of 800G/1ms
and an operating shock tolerance of 250G/2ms.
