Beyond Create and Modify: Purpose-built for Sequential Write Workloads

As cloud and hyperscale data centers look for affordable options to capture
the growing volume and variety of data, Western Digital delivers the world’s
first enterprise-class 15TB HDD, a new capacity high for our Ultrastar® DC HC620*
product line. This 3.5-inch hard drive is part of our Ultrastar DC HC600 series
portfolio, which is based on host-managed shingled magnetic recording (SMR)
technology, designed to help address Big Data challenges and the emerging
sequential write workload segment in the data center. Optimized to deliver the
highest capacity at low total cost of ownership (TCO), the DC HC620 provides
unprecedented capacity leadership by harnessing two core complementary
technologies—4th generation HelioSeal® technology and 2nd generation hostmanaged
SMR. These field-proven technologies provide the foundation for
delivering efficiency, quality and reliable performance required by cloud and
hyperscale data centers.
