Western Digital launches innovative Ultrastar® DC HC560 and WD Gold™ 20TB storage drives with OptiNAND.
The Ultrastar® DC HC560 and WD Gold™ 20TB with OptiNAND deliver an unsurpassed 20TB capacity on a proven 9-disk platform (2.2TB/platter) with CMR recording format, providing drop-in simplicity to help customers store vast amounts of data.
They also feature industry-first technologies such as energy-assisted magnetic recording (EAMR), triple-stage actuator (TSA), and HelioSeal® to enable the highest capacities with low power.
WD Gold HDD
Conquering Tough Workloads With Enterprise-class HDDs
Available in 1TB to 20TB¹ capacities, these highly reliable solutions for demanding storage environments provide up to 2.5M hours MTBF, vibration protection technology and a low power draw thanks to HelioSeal® technology (for 12TB and above). Specifically designed for use in enterprise-class data centers and storage systems, the WD Gold SATA HDDs deliver the world-class performance you expect from Western Digital® hard drives.
Beyond Expectations
WD Gold hard drives are performance-optimized for heavy application workloads and are designed to handle workloads up to 550TB2 per year. Available in capacities of 1TB to 20TB1 , WD Gold HDDs solve for the most demanding storage environments.
Enhanced Reliability
With up to 2.5M hours MTBF, WD Gold hard drives deliver enhanced levels of dependability and durability. Built for yearly operation (24x7x365) within the most demanding storage environments.
Vibration Protection
WD Gold has sophisticated monitoring electronics that help correct linear and rotational vibrations in real time using enhanced vibration protection technology for improved performance in high-vibration environments.
Play Well with Others
Specifically designed for use in enterprise-grade storage systems and data centers, the WD Gold SATA HDD is broadly compatible with major enterprise operating systems.
Reimagining the HDD
WD Gold offers 20TB1 on a 9-disk CMR drive with reimagined HDDs utilizing the first implementation of OptiNAND™ technology’s capacity-enabling features.
Leading the Way
Energy-assisted magnetic recording (EAMR) technology enables higher media precision and increases areal density. The triple-stage actuator (TSA) enhances the accuracy of head-positioning and delivers better performance and data integrity to also increase areal density. Both EAMR and TSA are available only in 16TB1 capacities and above.
5-Year Limited Warranty
Every WD Gold HDD comes with a 5-year limited warranty, so you can be confident in your storage.
Product Highlights
Ultrastar® DC HC560
Reimagining the HDD for Exponential Data Growth
Hyperscale cloud, CSPs, enterprises, smart video surveillance partners, NAS suppliers and more, need storage solutions to meet the exponential growth in data creation. When it comes to cost-effective storage of data at scale, hard disk drives (HDDs) continue to play a central role. IDC projects that in 2025, HDDs will represent 82% of storage capacity sold to the enterprise market*. HDDs deliver the capacity, performance, and reliability needed to store vast amounts of data today and well into the future. Investments in HDD technology remain critical to supporting worldwide data growth.
Western Digital has developed flash-enhanced drives with OptiNAND™ technology by vertically integrating the company’s leading NAND flash with its world-class HDDs. Western Digital HDDs have been leaders in areal density with industry first technologies of energy-assisted magnetic recording technology (EAMR), triple-stage actuator (TSA), HelioSeal®, and now OptiNAND technology. Higher areal density means higher capacities to meet storage challenges.
20TB HDDs with OptiNAND Technology
OptiNAND integrates an iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and incorporates innovative changes to the firmware algorithm and system-on-a-chip (SoC). OptiNAND is not a hybrid technology. The drive works smarter, with enhanced firmware algorithms taking advantage of expanded metadata that has been offloaded to the iNAND, enabling more tracks per inch (TPI) with resulting in increased areal density.
The Ultrastar DC HC560, with the first implementation of OptiNAND technology’s capacity-enabling features, delivers an unbeaten 20TB capacity in a nine-disk platform (2.2TB/platter) with CMR recording format.
Trusted Reliability and Quality for Data at Scale
The Ultrastar DC HC560 meets modern data center reliability requirements with 2.5M MTBF (projected) and a 5-year limited warranty. It offers security and encryption options to help protect data from unauthorized use, including SED models.
Trust Western Digital and the Ultrastar DC HC560 hard drive to deliver the highest capacity and greatest value for your data center.
