Hitachi Endurastar J4K50 Hard Drives
Built Like a Tank
Hitachi 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 30GB 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 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 rigors 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.
Highlights
- Highest capacity Automotive HDD at 50GB; 67% more than prior model.
- Expanded operating temperature range from -30° C to +85° C.
- Highest operating altitude range of up to 5000 meters.
- 4th generation product, based on proven technology.
