HGST delivers an industry leading 320GB capacity in its latest Endurastar line of 2.5-Inch hard drives designed especially for extreme environments. The Endurstar J4K320 models provide up to three times the capacity of their predecessors and are built to operate at altitudes of up to 5500 meters. The Endurastar J4K320 is designed for the most severe conditions, with an operating temperature range of -30oC to +85oC. The drives are offered in a SATA 1.5Gb/s interface and leverage Advanced Format, which increases the physical sector size on hard drives from 512 bytes to 4096 (4K) bytes to increase drive capacities and improve error correction capabilities. Consult the HGST Advanced Format Technology Brief for more information on using these hard drives. Endurastar hard drives are built to meet the rigors of the automotive environment and are ideal to support automotive applications including navigation, telematics, in-car entertainment and vehicle relational management. Leveraging a proven 6th generation platform, the Endurastar J4K320 delivers the right blend of capacity and performance to meet the needs of extreme conditions found in automotive environments. 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 and compensates for variations caused by altitude and temperature changes. Perpendicular magnetic recording (PMR) technology on Endurastar J4K320 delivers 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.
