Built like a tank
Hitachi is first to deliver a 50GB per platter Endurastar hard drive for use in extreme environ-
ments. The Endurastar J4K50 and N4K50 are offered in capacities of 30 to 50GB. Along with
the increased capacity, comes a wider temperature range and improved altitude range. Endur-
astar J4K50 is designed to operate in the most severe conditions, at temperatures of -30°C to
+85°C and altitudes of -300 to +5000 meters.Endurastar N4K50 offers a temperature range of
-16°C to +70°C at altitudes of -300 to 3000 meters. The new Endurastar models continue to
leverage shock sensor technology for enhanced reliability and the proven technology
of Hitachi HDDs for notebook PCs to deliver quiet acoustics and excellent performance.
Hitachi Endurastar drives are designed to guard and deliver your data under the harshest
environmental conditions.

Made for the road
Hitachi Endurastar hard drives deliver the one-two punch of operating at the highest
altitude and the most extreme temperatures. These drives are designed to meet the rig-
ors of the automotive environment, including traditional navigation, telematics, in-car
entertainment and vehicle relational management. This time-proven design supports
around-the-clock applications in industrial environments.

The implementation of TFC, which enables direct control of the read/write element using heat,
provides more consistent spacing between the read/write element and the media, thereby
improving robustness and performance. These new Endurastar models are preferred for
applications in the most radical environments ranging from desert heat to Antartic chill.
