Western Digital has unveiled its new 22TB CMR and 26TB UltraSMR hd drives (HDDs
(opens in new tab)
) which are now being tested by select hyperscale deject customers.

The reason the storage giant has been able to significantly expand the capacity of HDDs over the years is due to its always expanding engineering science portfolio which includes its unique OptiNAND

engineering, free energy-assisted PMR (ePMR
(opens in new tab)
), triple-stage actuator (TSA

and at present UltraSMR.

Western Digital’s new ePMR drives leverage the company’s OptiNAND engineering science to unlock higher levels of chapters, performance and information resiliency. For instance, its new 22TB CMR HDD incorporates OptiNAND to evangelize areal density on a 2.2TB/platter HelioSeal platform with ten disks.

While the boilerplate consumer likely doesn’t have a need for such a high capacity bulldoze

services for end users.

UltraSMR

By combining OptiNAND with proprietary firmware that leverages HDD system-level hardware advancements, Western Digital’south new UltraSMR engineering introduces large block encoding with an advanced error correction algorithm that increases track-per-inch (TPI) to enable higher chapters HDDs.

The first HDD to use this new technology is the company’s new 26TB Ultrastar DC HC670 UltraSMR HDD that features 2.6TB per platter and offers eighteen percent more storage capacity. Notwithstanding, as cloud service providers are increasingly adding SMR to their datacenter roadmaps, the drive’due south 26TB capacity could serve as a tipping signal to advance adoption.

, maxim:

“Every bit a longstanding partner of the industry’southward leading cloud providers, we understand their unique requirements in building next-generation cloud infrastructure and invested in several HDD innovations we developed alongside our areal density engineering science. Our intent with taking this development strategy was non only to address the chapters demands of the world’south largest cloud titans but to deliver on a roadmap that would as well back up the evolving economic science of their data centers for decades to come. With ePMR, OptiNAND and at present UltraSMR as the foundation of Western Digital’s HDD roadmap, our deject customers can keep speedily scaling their business past taking advantage of our innovations to lower their storage TCO.”

The 22TB Ultrastar DC HC570 HDD will presently brainstorm volume shipments to the channel while the 26TB Ultrastar DC HC670 UltraSMR HDD is fix to brainstorm shipping to select customers this summer.
