This 11-disk HDD platform delivers a capacity of up to 26TB (CMR) to help quench customers' insatiable demand for increased storage density in the existing storage footprint.

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.

The higher storage density provided by 11 disks, combined with WD's energy-assisted Perpendicular Magnetic Recording (ePMR) technology which increases tracks-per-inch (TPI), allows data centers to maximize their storage efficiency.

Western Digital's 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, it offers exceptional drive reliability and protection from unexpected shock events.

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

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.

The stable internal environment created by WD's HelioSeal technology enables this high-capacity helium drive to deliver a low power profile.
