HGST Ultrastar A7K2000:

3.5-inch Enterprise SATA Hard Disk Drives

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 at impressively low power-consumption rates. The Ultrastar A7K2000 also features HGST-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 HGST a reputation among server and storage vendors as a global partner dedicated to delivering the highest quality and reliability in the industry.

Doubling the capacity density
As data center professionals across the globe work to meet growing enterprise needs, they face the dilemma of storing more data in the same footprint while also reducing power and HVAC consumption. The new Ultrastar™ A7K2000 provides twice the data storage capacity of the prior generation Ultrastar A7K1000 drive, and does so using fewer watts. It is now possible to achieve a colossal 1.2 petabytes (PB) in the footprint of a standard 19-inch enterprise storage rack by deploying the 2TB A7K2000 in a stack of ten 4U, 60-bay enclosures.

Combining 7200 RPM performance and granular power control
Operating at 7200 RPM, the HGST Ultrastar A7K2000 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 HGST 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 softwarebased encryption solutions, the HGST 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.

Delivering industry-leading reliability
With a robust fourth-generation mechanical design, Ultrastar A7K2000 is specifically built and tested for the enterprise. The Ultrastar SATA drive family features HGST-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 HGST a reputation among server and storage vendors as a global partner dedicated to delivering the highest quality and reliability in the industry.

HGST Ultrastar 7K3000:

3.5-inch Enterprise 7200 RPM SATA Hard Disk Drives

The HGST Ultrastar™ 7K3000 is the world's first and only 7200 RPM hard drive rated at 2.0 million hours MTBF and backed by a five-year limited warranty. The Ultrastar 7K3000 represents the fifth-generation HGST 5-platter mechanical design, first introduced in 2004, and has been field proven by top server and storage OEMs as well as leading Internet giants. When the highest quality and reliability are a top requirement, customer field data proves that the Ultrastar 7K3000 delivers by reducing downtime, eliminating service calls and keeping TCO to a minimum. Engineered for the highest reliability, the Ultrastar 7K3000 is not only put through grueling design tests during development but must also pass stringent ongoing reliability testing during manufacturing. Across the entire Ultrastar family, world-class quality control, combined with scientific root-cause analysis and multi-faceted corrective actions, ensure that HGST GST remains the recognized leader in quality and reliability for enterprise-class hard drives.

Increasing capacity density by 50%
Recent measures such as data de-duplication and thin provisioning have not been able to stem the explosive petabyte (PB) growth requirements in cloud storage and data centers. Pervasive Internet computing with remotely stored email, pictures and social media, all being accessed from light-weight tablet and notebook computers, is changing consumer expectations. Ongoing worldwide government data retention regulations and security requirements are also driving up data center and private cloud storage needs. At the same time, tile space and megawatts remain at a premium, while in some highly built-out metropolitan areas both are at an absolute "no-growth" state. To meet these demands, the Ultrastar 7K3000 delivers 50% more capacity in the same footprint and does so at a 32% reduction in watts/GB versus our prior generation Ultrastar A7K2000 product. It is now possible to achieve a colossal 1.8 PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U, 60-bay enclosures.

Offering choices of interface and encryption
The HGST Ultrastar 7K3000 is the first HGST 7200 RPM drive available in both 6Gb/s SATA and 6Gb/s SAS interfaces and also available in two encryption options. The Ultrastar 7K3000 SATA model integrates easily with legacy SATA and Fibre Channel to SATA environments. The Ultrastar 7K3000 SATA model is available with a bulk data encryption (BDE) option. The Ultrastar 7K3000 dual-port SAS model is targeted at emerging 6Gb/s SAS enterprise infrastructure and is available with industry standard TCG Enterprise_A encryption. When enabled, both of these hardware-based implementations encrypt all data on the drive using a private security key as it is written to the disk, and then decrypt it with the key as it is retrieved, giving users an extreme level of data protection. These security options not only protect sensitive data but also reduce the time and effort involved in re-deploying hard drives since without the key, the data is unrecoverable.

Combining 7200 RPM performance and granular power control
Operating at 7200 RPM, the HGST Ultrastar 7K3000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power consumption rates. When compared to HGST's previous generation Ultrastar A7K2000, the 7K3000 is up to 3 times faster in sustained data transfer rates. The Ultrastar 7K3000 can help data centers achieve lower AC power and HVAC requirements. With five Advanced Power Management modes, the Ultrastar 7K3000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 1W during standby/sleep modes, freeing up precious headroom for growing enterprise needs.

Innovating for a more sustainable environment
The Ultrastar 7K3000 demonstrates HGST ecological leadership with its halogen-free design and power-efficient operation. Both these features serve to qualify the drive for the HGST EcoTrac classification, which identifies products that minimize environmental impact in the areas of product design, manufacturing, operation and disposal.
