The 22TB CMR HDD incorporates OptiNAND to deliver areal-density leadership on a mature 2.2TB/platter HelioSeal platform with ten disks.

Western Digital’s new UltraSMR technology introduces large block encoding along with an advanced error correction algorithm that increases tracks-per-inch (TPI) to enable higher capacity.

The result is Western Digital’s new 26TB Ultrastar DC HC670 UltraSMR HDD that delivers 2.6TB per platter, offering 18 percent more capacity for cloud customers optimizing their stacks to take advantage of the benefits of SMR.

The HDDs also include the ArmorCache write cache data safety feature, which gives customers the performance of write cache enable (WCE) combined with the data protection of write cache disable (WCD) for added data protection or resiliency in case of an emergency power off (EPO).

At common HDD application transfer lengths of 256KB or greater, IOPS and throughput improve by more than 40 percent relative to a non-OptiNAND drives, with a peak improvement of over 80 percent at 1MB transfer length. See the tech brief here for more details.

Western Digital said the 22TB Ultrastar DC HC570 HDD and the new 26TB Ultrastar DC HC670 UltraSMR HDD are now sampling to select hyperscale customers. The DC HC570 HDD will begin volume shipments to the channel, and the UltraSMR HDD will begin shipping to select customers in the summer of 2022.

The Ultrastar Data60and Data102JBODs will feature the new 22TB CMR Ultrastar HDDs this summer, delivering the industry’s highest storage density in a fully optimized platform for added durability and data reliability for software-defined storage.

Western Digital will deliver 22TB WD Purple Pro HDDs for smart video/surveillance, WD Red Pro HDDs for NAS solutions, and WD Gold HDDs for system integrators and resellers serving enterprises and SMBs. These drives will be available this summer.
