Western Digital Reveals World’s First High Capacity UltraSMR HDD

Western Digital has announced the release of the world’s first 22TB CMR and 26TB UltraSMR hard disk drives (HDDs). These HDDs are the first of their kind in the industry, and they’re currently being evaluated by a few hyper-scale cloud customers.

Western Digital’s latest hard drives take advantage of the company’s OptiNAND technology to boost capacity, speed, and data resiliency. The new 22TB CMR HDD, which uses this technology, can provide areal density on a 2.2TB/platter HelioSeal platform with 10 disks.

This will enable cloud computing providers to store more data in less space, lowering the cost of cloud storage services in the long run.

The new HDDs’ UltraSMR technology combines OptiNAND technology with the company’s own firmware for hardware upgrades. Large block encoding with an enhanced error correction algorithm enhances track-per-inch (TPI) to enable greater capacity HDDs.

The Ultrastar DC HC670 UltraSMR HDD, which has a capacity of 26TB, is the first to utilise this technology. It has a storage capacity of 18% larger than before, with 2.6TB per platter.

The 22TB Ultrastar DC HC570 HDD will be available to data center customers soon, while the 26TB Ultrastar DC HC670 UltraSMR HDD will be available to a limited number of customers later this summer.
