Enterprise-Grade Internal Hard Drive: HGST Ultrastar 7K4000 4TB

The HGST Ultrastar A7K4000 is an enterprise-class, 7200 RPM, SATA III 6.0Gb/s 4TB hard drive designed for high-capacity nearline environments. It is built to deliver industry-leading reliability and enhanced data safety and security.

To ensure the utmost in data safety and security, the Ultrastar A7K4000 is available with a bulk data encryption (BDE) option. When enabled, the Hitachi BDE implementation encrypts all data on the drive using a private security key as it is written to the disk, and then decrypts it with the key as it is retrieved, providing users with an extreme level of data protection. Unlike software-based encryption solutions, the Hitachi BDE implementation is hardware-based, ensuring that it does not slow down the system. This technology also speeds up and simplifies the drive re-deployment and decommissioning process, as deleting the encryption key renders the data unreadable, eliminating the need for time-consuming, multi-pattern data overwrite.

The Ultrastar A7K4000 is built and tested specifically for the enterprise, with a robust fourth-generation mechanical design. The Ultrastar SATA drive family features Hitachi-patented Rotational Vibration Safeguard (RVS) sensor technology, which optimizes drive reliability in multi-drive RAID arrays and rack-mounted systems. Backed by a five-year warranty, the Ultrastar platform has earned Hitachi a reputation among server and storage vendors as a global partner dedicated to delivering the highest quality and reliability in the industry.

The HGST Ultrastar A7K4000 is a versatile hard drive that can be used in a variety of applications, including power PC/workstation servers, CCTV DVR security and surveillance systems, NAS (Network Attached Storage), and RAID systems. With a 4TB capacity, 7200RPM rotation speed, and 64MB cache, the Ultrastar A7K4000 is designed for 24/7 reliable operation.

All HGST Ultrastar A7K4000 hard drives are factory-tested and re-certified by state-of-the-art software, undergoing a full "sector-by-sector" test to ensure the best possible HDD quality, with zero bad sectors. This provides users with a worry-free return policy and a 100% full refund guarantee.

In conclusion, the HGST Ultrastar A7K4000 is an enterprise-grade, heavy-duty hard drive that offers exceptional data safety, security, and reliability, making it an ideal choice for a wide range of high-capacity nearline applications.
