20 TB storage capacity in an advanced HDD

The evolution of HDDs to handle growing data volumes is crucial. Hyperscale cloud, cloud services, enterprises, intelligent video surveillance, NAS, and other storage-intensive applications require solutions that can manage the exponential growth of data. When it comes to cost-effective storage with large capacity, HDDs will continue to play a central role. HDDs provide the necessary capacity, performance, and reliability to store massive amounts of data today and in the future. Investments in HDD technology remain a critical solution for global data growth.

Western Digital has developed flash-based hard drives with OptiNAND™ technology through the vertical integration of its leading NAND flash into its top-tier HDDs. Western Digital HDDs feature leading areal density thanks to revolutionary technologies such as EAMR (Energy-Assisted Magnetic Recording), TSA (Triple-Stage Actuator), HelioSeal®, and now OptiNAND. The higher areal density results in greater capacity to meet the challenges of data growth.

20 TB HDDs with OptiNAND technology

OptiNAND combines iNAND® UFS EFD storage (Universal Flash Storage Embedded Flash Drive) with the proven rotating storage medium and makes innovative changes to the firmware algorithm and SoC (System-on-a-Chip). However, OptiNAND is not a hybrid technology. Thanks to improved firmware algorithms, the hard drives become smarter: they leverage the extensive metadata that has been offloaded to the iNAND, allowing for more TPI (Tracks Per Inch) and greater areal density to be achieved.
