Increase capacity and decrease TCO forCloud and Enterprise Data Centers
The breadth and depth of big data creates a universal need for higher capacities across a broad spectrum of applications and workloads. As the foundation for a worry-free data center, Western Digital delivers the capacity to overcome the data explosion - the 18TB Ultrastar. DC HC550 hard drive. Built using HelioSeal technology, the industry's only fifth-generation helium platform and the foundation for our high-capacity DC-HC500 series, the Ultrastar DC HC550 is designed for public and private cloud environments where storage density, Watt / 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 a lower total cost of ownership (TCO) for cloud and enterprise customers.

HelioSeal technology helps solve challenges related to next-generation data centers.
Data centers are facing increasing pressure. The data volume increases, the operating costs increase, but the budgets remain the same. HelioSeal technology enables the Ultrastar DC HC550 to deliver one of the lowest power profiles in the industry, enabling data center architects to meet ecological environmental goals and requirements. Designed to handle workloads of up to 550 TB per year, the Ultrastar DC HC550 is based on conventional magnetic recording (CMR) technology for drop-in simplicity in enterprise and cloud data centers. Features such as two-dimensional magnetic recording (TDMR) technology and a third-generation dual-stage micro-actuator work together to improve head positioning accuracy and deliver better performance, data integrity and overall drive reliability, essential in environments with multiple drives where operational vibrations are present. A choice of 6 Gb / s SATA or 12 Gb / s SAS interface allows easy integration into high performance data center. Rely on Western Digital and the Ultrastar DC HC550 hard drive for more capacity, more efficiency, more reliability and more value for your data center.

Data durability and data security features to support compliance and privacy requirements
Since disk capacity is greater than single-digit TBs, erasure encrypted object storage systems generally provide better data durability compared to RAID systems, given their tolerance for concurrent errors. The Ultrastar DC HC550 is ideal for object storage deployments with its massive capacity and unmatched reliability rating. Compliance and privacy requirements drive the need for increased data security. The Ultrastar DC HC550 offers security and encryption options to protect data from unauthorized use, including TCG SAS models.
