With a robust fourth-generation mechanical design, Ultrastar A7K2000 is specifically built and tested for the Enterprise. Operating at 7200 RPM, it offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power consumption rates. The Ultrastar A7K2000 also features HGST’s exclusive Rotational Vibration Safeguard (RVS) sensor technology to deliver the highest quality and reliability in the industry.
Industry-leading Reliability The Hitachi Ultrastar A7K2000 hard drive offers industry leading reliability with 1.2 million hours MTBF rating. It also features HGST’s Rotational Vibration Safeguard (RVS) sensor technology, which optimizes drive reliability in multi-drive RAID arrays and rack-mounted systems.
Combining 7200 RPM performance and granular power control Operating at 7200 RPM, the HGST Ultrastar 7K2000 offers better overall performance than slower-RPM, capacity-oriented drives at impressively low power-consumption rates. When compared to the previous generation Ultrastar A7K1000, the A7K2000 offers up to a 155% improvement in sustained data transfer rate, and a 120% improvement in watts-per-GB. With five Advanced Power Management modes, a 36% reduction in watts during low-RPM idle mode, and using less than 1W during standby/sleep mode, the Ultrastar A7K2000 can help data centers achieve lower AC power and HVAC requirements, freeing up precious headroom for growing enterprise needs.
Enhancing data safety and security To ensure the utmost in data safety and security, the Ultrastar A7K2000 is also 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, giving users an extreme level of data protection. Unlike software-based encryption solutions, the Hitachi BDE implementation is hardware-based, so it doesn’t slow the system down. This technology also speeds up and simplifies the drive re-deployment and decommissioning process. By deleting the encryption key, the data is rendered unreadable, thereby eliminating the need for time-consuming, multi-pattern data overwrite.
Innovation for a more sustainable environment The Ultrastar A7K2000 demonstrates Hitachi's ecological leadership with its halogen-free design and power-efficient operation. Both of these features serve to qualify the drive for the Hitachi EcoTrac classification, which identifies products that minimize environmental impact in the areas of product design, manufacturing, operation and disposal.
