Endurastar J4K30 30GB HDD, ATA-5
Extreme hard drives for extreme environments
-30GB and 20GB capacity in a 2.5-inch form factor.
-Operating temperature range from -20° C to +85° C.
-Built-in shock sensor enhances data integrity.
-Enhanced moisture control system ensures corrosion control in extreme environments.
Turn up the Heat
Hitachi delivers a 50-percent storage capacity increase in its line of “extreme” hard disk drives. The Endurstar J4K30 and Endurastar N4K30 are both offered in capacities of up to 30GB, and are designed specifically to perform in extreme temperature environments. With an operating temperature range as wide as -20°C to +85°C, the new Endurastar models are built to perform in the harshest environments—from the desert heat to the Antarctic chill.
Ideal for Automotive Applications
Endurastar hard drives are the preferred solution for automotive applications or other environments which require high robustness and wider operating temperatures than standard hard drive applications. In fact, the Endurastar J4K30 is already being used in car entertainment and navigation applications—and 30GBs of storage means users can store more than 5,000 audio files, four hours of MPEG2 video and enough navigation data to cover the entire planet!
Reliability and Performance
The new Endurastar models feature glass media and load/unload technology in addition to shock sensor technology which cushions the drive in less than ideal shock or vibration conditions. Endurastar drives incorporate fluid dynamic bearings (FDB) in the spindle motor, allowing the same quiet operations and improved shock characteristics as with PC models, but offers even higher reliability for automotive environments. These features enable the Endurastar drives to employ a non-operating shock tolerance of 800G/1ms and an operating shock tolerance of 250G/2ms.
Applications
-Automotive
-GPS navigation systems
-Applications running in hot and humid climates
