HGST Ships New Endurastar Automotive Hard Drive


HGST is shipping a new Endurastar J4K320 family, a single-platter hard disk drive (HDD) specifically designed for the automotive infotainment and telematics markets.



As HGST's sixth generation automotive HDD, the new Endurastar J4K320 family is built to operate in extreme and varying temperatures and altitudes. The Endurastar J4K320 operates at altitudes of up to 5500 meters (18,044.62 feet), supports an operating temperature range of -30C to +85C (-22F to 185F), and has improved operating shock tolerance of 300G (2ms) and a non-operating shock of 800G (ms).

In early in 2006, HGST was granted a patent for its Thermal Fly-height Control (TFC) feature, which can compensate the head/media distance variations caused by altitude and temperature changes. The company says it has designed and tested the Endurastar J4K320 HDD beyond most industry specifications. The Endurastar J4K320 is HGST's second-generation automotive HDD to apply TFC.

The Endurastar J4K320 family comes in 320GB, 250GB, 200GB, 100GB and 80GB capacities, operates at 4260 RPMs and features a SATA interface. The drive family is based on a standard 9.5mm 2.5-inch form factor.

The HGST Endurastar J4K320 family is currently shipping.
