Hitachi Endurastar N4K20 20 GB

Hitachi Endurastar N4K20 20 GB ... creates a new generation of hard drives to meet the expanding needs of emerging markets.

Built to operate in temperature ranges of up to -20° C to +85° C, the Hitachi Endurastar hard disk drives are the only drives available in the market today which support the environmental conditions commonly found in the automotive industry. These drives are the ideal choice for automotive applications, including car navigation and car audio products.

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.

The N4K20 incorporates fluid dynamic bearings (FDB) in the spindle motor, re-designed to support a wider temperature range. The new FDB allows the same quiet operation 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 100G/11ms.
