Driving Up Capacity and Driving Down TCO for

Cloud and Enterprise Data Centers

The breadth and depth of big data is driving the universal need for higher capacities

across a broad spectrum of applications and workloads. Laying the foundation for a worry-

free data center, Western Digital delivers capacity to conquer the data explosion–the 14TB

Ultrastar

DC HC530 hard drive. Built using HelioSeal technology, the industry’s only ﬁfth-

generation helium platform and the basis for our high-capacity DC HC500 series, Ultrastar

DC HC530 was designed for public and private cloud environments where storage

density, Watts/TB and $/TB are critical parameters for creating the most cost-efﬁcient

infrastructure. HelioSeal technology is key to achieving higher drive capacities, higher

reliability ratings and extreme power efﬁciency for lower levels of total cost of ownership

(TCO) for cloud and enterprise customers.

HelioSeal Technology Helps Solve Challenges

Facing Next Generation Data Centers

Data centers are facing growing pressures. Data volume is expanding, operating costs

are rising, yet budgets remain ﬂat. HelioSeal technology enables Ultrastar DC HC530 to

deliver one of the lowest power proﬁles in the industry, helping data center architects

meet eco-environmental goals and requirements. Designed to handle workloads up to

550TB per year, the Ultrastar DC HC530 is based on conventional magnetic recording

(CMR) technology for drop-in simplicity in enterprise and cloud data centers. Features like

TDMR technology (two-dimensional magnetic recording) and a third-generation dual-

stage microactuator work together to enhance head-positioning accuracy and deliver

better performance, data integrity and overall drive reliability, critical in multi-drive

environments where operational vibration is present. A choice of 6Gb/s SATA or 12Gb/s

SAS interface enables easy integration into high performance data centers. Trust Western

Digital and the Ultrastar DC HC530 hard drive to deliver more capacity, more efﬁciency,

more reliability and more value to your data center.

Data Durability and Data Security Features to

Support Compliance and Privacy Requirements

As drive capacity grows beyond single-digit TBs, object storage systems with erasure

coding generally provide better data durability compared to RAID systems, given its

tolerance for simultaneous error conditions. The Ultrastar DC HC530 is ideal for object

storage implementations with its massive capacity and an unbeaten reliability rating.

Compliance and privacy requirements drive the need for increased data security. The

Ultrastar DC HC530 offers security and encryption options to help protect data from

unauthorized use, on both SATA and SAS models.
