HGST 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. 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. These new Endurastar drives leverage time proven technologies pioneered on HGST 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.
