3.5IN 26.1 26TB 512 7200RPM SAS ULTRA 512E SE P3 DC HC590

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

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.
