Hitachi Endurastar J4K50 50.0GB 4260RPM Ultra ATA-100Mb/s 8MB Cache 2.5" 9.5mm Laptop Hard Drive - HEJ425050F9AT00

HGST is first to deliver a 50GB per platter Endurastar hard drive for use in extreme environments. 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. Endurastar 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 HGST HDDs for notebook PCs to deliver quiet acoustics and excellent performance. HGST Endurastar drives are designed to guard and deliver your data under the harshest environmental conditions. HGST 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 rigors of the automotive environment, including traditional navigation, telematics, in car entertainment and vehicle relational management. 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.
