Western Digital Ultrastar DC HC590 26TB 3.5 inch Data Center Hard Drive

Western Digital Ultrastar DC HC590 26TB 3.5" SATA 7200RPM Data Centre Hard Drive

Feature

Massive 26TB Capacity with 11-Disk CMR Platform

The HC590 is the world’s first 11-disk Conventional Magnetic Recording (CMR) hard drive, delivering an impressive 26TB of storage in a standard 3.5" form factor—ideal for maximizing storage density without increasing physical footprint.

Enhanced Performance with OptiNAND™ Technology

Western Digital’s proprietary OptiNAND integrates embedded flash to offload metadata and improve performance, reliability, and usable capacity, especially in write-intensive environments.

Energy-Assisted PMR and HelioSeal® for Efficiency

Featuring energy-assisted Perpendicular Magnetic Recording (ePMR) and sealed with helium, the drive reduces turbulence and power consumption while increasing areal density and operational efficiency.

Enterprise-Grade Durability and Reliability

With a projected 2.5 million hour MTBF, 5-year limited warranty, and Rotational Vibration Safeguard (RVS), the HC590 is built for 24/7 operation in demanding data center environments.

Flexible Write Cache Modes with ArmorCache

Offers both Write Cache Disabled (WCD) for enhanced random write performance and Write Cache Enabled (WCE) for data protection during unexpected power loss, giving users flexibility based on workload needs.

World’s first 11-disk CMR HDD platform for increased storage density.

Western digital Ultrastar Data Center HC590 hard drives combine field-proven designs with the latest innovative technologies to meet data center demands for increased storage density in the existing storage footprint.

Future of More. Plus One

The world’s first 11-disk CMR HDD platform delivers unbeaten capacity of up to 26TB to help quench customer’s insatiable demand for increased storage density in the existing storage footprint.

Rapid Qualification and Rock Solid Reliability

Leveraging field-proven hardware and firmware designs from generations of highly successful products ensures easy qualification, seamless integration and rapid adoption while maintaining superior dependability and reliability.

Maximum Rack-Space Efficiency

The higher storage density provided by 11 disks combined with our energy-assisted Perpendicular Magnetic Recording (ePMR) technologies, which increase tracks-per-inch (TPI), allow data centers to maximize their storage efficiency.

Protected Against Vibration & Shock

Our exclusive Rotational Vibration Safeguard (RVS) uses dual sensors to anticipate and counteract disturbances, maintaining peak performance in high-vibration environments. Combined with Dynamic Fly Height technology, Western Digital offers exceptional drive reliability and protection from unexpected shock events.

Engineered with Industry-Leading Technology

Western Digital’s proprietary OptiNAND™ technology leverages integrated iNAND® embedded flash to perform key housekeeping functions, freeing up more capacity and improving the overall drive performance.

Powerful Performance and Resiliency

Choose ArmorCache™ write cache disabled (WCD) mode for increased random write performance or select write cache enable (WCE) mode to protect cached data in case of Emergency Power Off (EPO) or unexpected power loss scenarios.

Meet Eco Goals with Helium

Choose ArmorCache™ write cache disabled (WCD) mode for increased random write performance or select write cache enable (WCE) mode to protect cached data in case of Emergency Power Off (EPO) or unexpected power loss scenarios.
