Western Digital Ultrastar DC HC590 24TB 3.5" SATA 7200RPM Data Centre Enterprise NAS Hard Drive

Massive 24TB Capacity with 11-Disk CMR Platform
The HC590 is the world’s first 11-disk Conventional Magnetic Recording (CMR) hard drive, delivering an impressive 24TB 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.
