Western Digital HDD 3.5" WD Ultrastar DC HC560 20 TB Serial ATA WUH722020BLE6L4

20 TB, 7200 rpm, SATA 6 Gbps, 3.5"

A newly defined HDD for exponential data growth
Hyperscale clouds, cloud service providers (CSPs), enterprises, smart video surveillance partners, NAS providers and others need storage solutions to meet the exponential growth of data creation. When it comes to costly, large-scale data storage, hard disk drives (HDDs) still play a key role. HDDs offer the capacity, performance, and reliability needed to store enormous amounts of data today and in the future. Investments in HDD technology remain critical to supporting global data growth.
Western Digital has engineered flash-memory-enabled drives with OptiNAND™ technology, combining our leading NAND flash memory with our best-in-class HDDs. Western Digital HDDs are leaders in areal density, introducing innovative technologies such as Energy-Assisted Magnetic Recording (EAMR), Three-Stage Actuator (TSA), HelioSeal®, and now OptiNAND technology. Higher areal density means higher capacities that can meet storage challenges.
20TB HDDs with OptiNAND technology
OptiNAND integrates iNAND® Universal Flash Memory (UFS) with traditional spinning media and introduces innovative changes to firmware and system-on-chip (SoC) firmware. OptiNAND is not hybrid technology. The drive operates smarter, with improved firmware algorithms that leverage extended metadata that has been moved to iNAND, enabling more bits per track (TPI) and resulting in increased areal density.
Ultrastar DC HC560, with the first implementation of OptiNAND capacity-enabling features, offers unparalleled 20TB capacity on a nine-disk platform (2.2TB per platter) with CMR recording format.
Trusted reliability and quality for data at scale

Trust Western Digital and the Ultrastar DC HC560 HDD to deliver the highest capacity and greatest value for your data center.
