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 30 to 50GB. [. . . ] 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.
