Western Digital announces that it has started shipping its high-capacity HDD samples to enterprise OEMs and hyperscale customers worldwide, so that users can efficiently scale their data centers for the zettabyte era.
The 20TB Ultrastar DC HC650 SMR HDDs and 18TB Ultrastar DC HC550 CMR HDDs, first previewed in June 2019, and announced in September 2019, feature its initial commercial implementation of energy-assisted magnetic recording technology on a nine-disk platform, enabling customers to more efficiently provision and scale their data center environments with improved total cost of ownership.
Optimized to deliver improved capacity and low TCO, the Ultrastar DC HC600 series provides unprecedented capacity capability by harnessing two core complementary technologies: HelioSeal technology and host-managed SMR (HM-SMR). These field-proven technologies provide the foundation for delivering efficiency, quality and reliable performance required by cloud and hyperscale data centers.
Unlike CMR drives, HM-SMR drives are not drop-in replacements for traditional drives and require system software modifications that take advantage of the new command sets to ensure data is written sequentially to the drive. This software investment helps yield cost-efficient storage solutions.
With zettabyte-scale data growth, the need for higher-capacity data storage across a broad spectrum of applications and workloads can be reliably met only with high capacity enterprise HDDs.
The capacities of Western Digital’s Ultrastar 20TB SMR and 18TB CMR HelioSeal HDDs enable customers to deploy up to 22 percent fewer racks and reduce their TCO by up to 11 percent, along with the corresponding reductions in power consumption, cooling costs, and data center infrastructure needs when compared with 14TB CMR HDDs.
Western Digital achieves high areal density performance in these drives through the innovative use of energy-assisted magnetic recording. Together with the company’s HelioSeal and SMR technologies, triple-stage micro actuation and 9-disk platform, the energy-assisted recording technology provides an integrated solution, resulting in the dramatic gain in drive capacities.
“The market outlook for capacity-optimized enterprise HDDs remains very positive as IDC expects petabytes shipped to hyperscale cloud data centers and for OEM storage systems and servers to grow at a combined compound annual growth rate of 28 percent through 2023,” said Ed Burns, Research Director, HDD and Storage Technologies at IDC. “Western Digital’s new 20TB and 18TB HDDs should make a compelling case for customers to transition to higher capacity points as they seek greater storage and energy efficiencies in the near-term while building more cost-effective and scalable infrastructures for the future.”
“Delivering samples of our Ultrastar 20TB SMR and 18TB CMR HDDs marks a significant milestone for Western Digital—demonstrating our enduring commitment to the open SMR-based ecosystem, as well as our strong track record of innovation to provide great value for our customers,” said Phil Bullinger, senior vice president and general manager of Western Digital’s Data Center Business Unit. “These new HDDs deliver unsurpassed capacity and are our first to leverage energy-assisted magnetic recording technology, enabling new levels of data center efficiency and driving value creation from data at scale.”
Western Digital is now sampling the 20TB Ultrastar DC HC650 SMR HDD and the 18TB Ultrastar DC HC550 CMR HDD, with qualification and volume shipments expected in the first half of next year.
