0F59373 WD Ultrastar DC HC590 24TB SAS 512 MB 3.5" Server HDD

High-Density 3.5in Datacenter SAS HDD for Bulk Storage Tiers with the 0F59373

The 0F59373 is a 24TB 3.5in internal datacenter HDD designed to expand capacity tiers in rack servers and JBOD enclosures where predictable throughput, serviceability, and fleet consistency are required. Using a 12Gb/s SAS interface, the 0F59373 integrates cleanly into dual-path enterprise backplanes and SAS HBAs, supporting scale-out architectures that prioritize availability and controlled rebuild behavior over peak IOPS.

Built on WD Ultrastar DC HC590 engineering, the 0F59373 uses EAMR with TDMR and OptiNAND to raise areal density while maintaining signal integrity under real datacenter conditions. A 512MB cache supports burst buffering and command queue efficiency, and the 512e format enables broad OS and storage stack compatibility while still aligning with modern block management. Rotational vibration safeguards help maintain performance uniformity in dense multi-drive chassis, and Secure Erase (SE) supports controlled decommissioning workflows.

Why Choose the 0F59373?

The 0F59373 delivers a strong density-to-slot profile for object storage, backup repositories, and distributed filesystems where $/TB efficiency and operational stability matter. With 24x7 duty-cycle design and 2.5M hours MTBF, the 0F59373 supports scalable deployments that rely on consistent drive behavior across large populations, reducing operational variance in capacity nodes and retention pools.

WD designs Ultrastar datacenter drives with a reliability-first approach focused on sustained workloads, firmware consistency, and compatibility with enterprise SAS ecosystems. This engineering aligns with modern data centre standards for high-density storage nodes, including vibration-aware chassis operation and secure lifecycle management.

Key Applications:

• High-density bulk storage tiers for servers and JBOD
• Backup and archive repositories
• Object storage and S3-compatible platforms
• Distributed filesystems and scale-out NAS
• Secondary storage for virtualisation environments

At Happyware - Server Hardware you benefit from non-binding offers tailored to your storage node and enclosure requirements, ensuring the 0F59373 is sourced and configured for your SAS topology and deployment timeline. For long-lived capacity tiers, you can also extend the warranty up to 6 years to strengthen operational planning and risk control.
