Reimagining the HDD for Exponential Data GrowthHyperscale 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. 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 our leading NAND flash with our 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 TechnologyOptiNAND 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 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 ScaleThe Ultrastar DC HC560 meets modern data center reliability requirements with 2.5M MTBF2 (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.

Highest Capacities for Lower TCOTotal Cost of Ownership (TCO) Drives the Data Center ArchitectureData center decisions are driven by TCO. Higher capacity hard drives play a leading role in reducing TCO. An 18TB data center HDD provides 29% more capacity in the same form factor as a 14TB HDD. Higher capacity HDDs enable data centers to lower CapEx by reducing supporting hardware and system level costs when compared to lower capacity drives. Helium-sealed, low power, high reliability drives reduce energy and maintenance costs, contributing to OpEx savings. For example, a data center using 18TB HDDs vs. 14TB HDDs can require 22% fewer racks while consuming 21% less power per TB at idle, resulting in significant overall TCO reduction for data center environments.Raising the Capacity Bar with New TechnologiesUltrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a new class of HDDs. 18TB capacity is achieved by combining technologies that improve areal density working together with technologies that improve performance and reduce power consumption.The first HDD in the industry to harness Energy-Assisted Magnetic Recording (EAMR) technology improves writability and therefore increases areal density.The industry’s first Triple Stage Actuator (TSA) enhances head-positioning accuracy, delivering better performance and increased areal density.HelioSeal® technology is the foundation for Western Digital’s high capacity HDDs and this is the 6th generation of HelioSeal product. Western Digital has shipped >65 million HelioSeal products to date.
