Large capacity, robust features for extreme environments

Hitachi delivers an industry-leading 100GB capacity in its latest Endurastar line of 2.5-inch

hard drives designed especially for extreme environments. The Endurstar J4K100 and

N4K100 models provide twice the capacity of their predecessors and are built to operate

at altitudes of up to 5500 meters. The Endurastar J4K100 is designed for the most severe

conditions, with an operating temperature range of -30ºC to +85ºC. For milder conditions, the

Endurastar N4K100 provides an operating temperature range of -20ºC to +75ºC. The drives

are offered in SATA and PATA interface options for design configuration flexibility.

ATA-6 and SATA 1.5Gb/s

Right choice for the road

Endurastar hard drives are built to meet the rigors of the automotive environment, including

navigation, telematics, in-car entertainment and vehicle relational management. The drives

have been designed using a proven 5th generation platform.

Rugged, durable design

These new Endurastar drives leverage time-proven technologies pioneered on Hitachi hard

drives for notebook PCs to deliver quiet acoustics and robust performance. FDB motors

provide quiet operation, and Thermal Fly-height Control (TFC) enhances reliability by

maintaining more consistent spacing between the read/write head and the disk. Already in

use across its other product lines, perpendicular magnetic recording (PMR) technology has

been implemented on Endurastar J4K100 and N4K100 to deliver excellent soft error rates for

improved reliability and performance under even the harshest environmental conditions.

All models come standard with proven shock sensor technology and enhanced humidity

absorption for superior reliability.
