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 Hitachi 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 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.

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 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.

Innovation for a more sustainable environment

The Ultrastar A7K2000 demonstrates Hitachi ecological leadership with its halogen-free

design and power-efficient operation. Both 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.

sample population and is estimated by statistical measurements and acceleration algorithms under nominal operating conditions. MTBF ratings are not intended

to predict an individual drive’s reliability. MTBF does not constitute a warranty.
