Built like a tank

Hitachi is first to deliver a 50GB per platter Endurastar hard drive for use in extreme environ- ments. The Endurastar J4K50 and N4K50 are offered in capacities of 30 to 50GB. Along with the increased capacity, comes a wider temperature range and improved altitude range. Endurastar J4K50 is designed to operate in the most severe conditions, at temperatures of -30°C to +85°C and altitudes of -300 to +5000 meters.Endurastar N4K50 offers a temperature range of -16°C to +70°C at altitudes of -300 to 3000 meters. The new Endurastar models con- tinue to leverage shock sensor technology for enhanced reliability and the proven technology of Hitachi HDDs for notebook PCs to deliver quiet acoustics and excellent performance. Hitachi Endurastar drives are designed to guard and deliver your data under the harshest environmental conditions.

50, 40 and 30GB 4200 RPM ATA-6

Made for the road

Hitachi Endurastar hard drives deliver the one-two punch of operating at the highest altitude and the most extreme temperatures. These drives are designed to meet the rigors of the automotive environment, including traditional navigation, telematics, in-car entertainment and vehicle relational management. This time-proven design supports around-the-clock applications in industrial environments.

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.

N4K50, J4K50 specifications

Hitachi's J4K50 and N4K50 are advanced hard disk drives designed to meet the increasing storage demands of modern enterprise applications. Geared towards data-intensive environments, both models leverage innovative technologies to optimize performance, reliability, and energy efficiency.

The J4K50 series is notable for its 4TB storage capacity, providing ample room for expansive data requirements. It features a 7200 RPM spindle speed, which ensures rapid data access and transfer rates, making the J4K50 ideal for applications such as large databases, backup solutions, and virtualization. The drive implements SATA III interface, enabling faster data throughput of up to 6 Gbps, which significantly enhances overall system responsiveness.

On the other hand, the N4K50, while also showcasing a 7200 RPM spindle speed, is tailored more towards nearline and cloud storage solutions. This model excels in environments where data integrity and longevity are paramount. It incorporates advanced error recovery features and a robust firmware design that minimizes downtime and maximizes accessibility. The N4K50 typically provides a similar 4TB capacity, yet its optimized architecture is particularly suited for large-scale data storage, big data analytics, and archiving.

Both models are equipped with Hitachi's exclusive technologies that bolster data integrity. The Integrated Cache (IC) system enhances read and write performance, allowing for a seamless flow of data even during high demand scenarios. Additionally, Advanced Format technology is utilized, which increases the sector size from 512 bytes to 4 KB, offering improved storage efficiency and error correction capabilities.

Energy efficiency is a hallmark of the J4K50 and N4K50 series. The drives come with features such as low power consumption, which not only reduces operating costs but also makes them a more sustainable choice for enterprises concerned with their environmental footprint.

In conclusion, the Hitachi J4K50 and N4K50 hard disk drives represent a perfect blend of capacity, performance, and reliability, making them invaluable assets for organizations aiming to improve their data storage solutions. With their tailored features and advanced technologies, they cater to diverse enterprise needs, from general-purpose storage to specialized applications requiring enhanced durability and efficiency.
