Rough and harsh terrain are fair game

HGST , a subsidiary of Western Digital, today announced it has begun shipping its new Endurastar J4K320 family of single platter hard drives specifically designed for automotive infotainment and telematics markets. The J4K320 line represents HGST's sixth generation of automotive HDDs and offers the highest capacity for such drives at 320GB. These drives are also built to handle extreme and varying temperatures and altitudes, HGST says.

Since your treks could take you to high altitudes in the Alps to scorching hot temperatures in the Sahara Desert, these types of drives carry different requirements than the ones that end up in your desktop PC or laptop. In this case, the Endurastar J4K320 operates at up 18,044 feet and supports an operating temperature range of -30C to +85C (-22F to 185F). It also has improved operating shock tolerance of 300G and a non-operating shock of 800G.

"HGST has been working with the automotive industry for nearly two decades to develop the right hard drive products for use in cars," said Brendan Collins , vice president of product marketing, HGST. "These onboard systems integrate a combination of entertainment (video, audio, radio), navigation, connectivity, security services, diagnosis and much more to help provide a seamless in-car user experience. The combination of these services, especially navigation, requires reliable and durable storage for the supporting application software, as well as the needed capacity to store end-user content. As our sixth generation automotive drive, our new Endurastar J4K320 drive family continues to deliver on the needed requirements, and provides long-term data stability and reliability for the automotive market."

HGST offers it Endurastar J4K320 family in 80GB, 100GB, 200GB, 250GB, and 320GB capacities, each operating at 4260 RPM with a SATA 1.5Gbps interface and a standard 9.5mm 2.5-inch form factor.
