WD Ultrastar 26TB 3.5" 7200 512MB SATA DC HC590 (WUH722626ALE6L4)

Features

The Ultrastar DC HC590 series hard drive is designed for data center use, where storage density and operational stability are critical. The 26 TB capacity allows large data sets to be stored within a standard 3.5" form factor.

The design is based on an 11-disk platform, increasing areal density without changing the drive dimensions and enabling efficient use of rack space.

The drive uses CMR technology and energy-assisted perpendicular magnetic recording (ePMR). This ensures predictable performance with large data volumes and stable operation in enterprise environments.

A helium-filled design is implemented to reduce internal resistance and stabilize thermal conditions. This approach supports efficient operation at high component density.

For multi-drive environments, a vibration protection system with dual sensors is used. The solution maintains stable performance under increased mechanical stress.

OptiNAND technology is used, combining magnetic recording with embedded flash memory for background operations. This improves space efficiency and overall drive performance.
