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),
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.
