Western Digital Ultrastar DC HC590 26TB - 7200 RPM 512MB SATA III Enterprise HDD - 0F65672 (Bulk)

Empower your data center with the groundbreaking Western Digital Ultrastar DC HC590 26TB Enterprise HDD (model 0F65672). Engineered to meet the insatiable demand for increased storage density, this massive 26TB drive utilizes the world's first 11-disk Conventional Magnetic Recording (CMR) architecture. Operating at 7200 RPM with a 512MB buffer and a SATA 6Gb/s interface, it maximizes rack-space efficiency without expanding your existing physical or thermal footprint. It is the perfect foundational storage solution for cloud environments, AI training pools, and converged infrastructures.

At the core of the Ultrastar DC HC590 lies Western Digital's exclusive energy-assisted Perpendicular Magnetic Recording (ePMR) and OptiNAND technology. By integrating iNAND embedded flash, the drive efficiently offloads critical housekeeping tasks, significantly improving metadata handling and overall performance. The internal environment is stabilized by HelioSeal technology, reducing internal air resistance to deliver one of the lowest power profiles in the industry. Additionally, ArmorCache technology offers users the flexibility to choose between Write Cache Disabled (WCD) mode for superior random write performance, or Write Cache Enable (WCE) mode for data protection during unexpected power loss events.

Designed for 24/7 reliability in densely packed server racks, the HC590 is equipped with dual-sensor Rotational Vibration Safeguard (RVS) and Dynamic Fly Height control. These features anticipate and counteract environmental disturbances to maintain peak read and write speeds. Rated for rigorous enterprise workloads of up to 550 TB/year, this robust 3.5-inch hard drive ensures that critical data remains accessible, secure, and protected against unexpected shock events.
