Western Digital Introduces New Enterprise Class 20TB HDDs

Western Digital has introduced new 20TB HDDs for use in high end hybrid work environment.


Available in 1TB to 20TB 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 20TB HDDs are suitable for the enterprise level work.

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 20TB, WD Gold HDDs work in demanding storage environments.

With up to 2.5M hours MTBF, these 20TB HDDs claim to deliver enhanced levels of dependability and durability. Built for yearly operation (24x7x365) within the most demanding storage environments.

WD Gold has advanced monitoring electronics that help correct linear and rotational vibrations in real time using enhanced vibration protection technology for improved performance in high-vibration environments.

WD Gold offers 20TB on a 9-disk CMR drive with reimagined HDDs utilising the first implementation of OptiNAND™ technology’s capacity-enabling features.

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.
