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.

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.

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 software-based 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.

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.

The Ultrastar A7K2000 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.
