0F48155 WD Ultrastar 22TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5-inch Enterprise SATA HDD for data centre tiers with the 0F48155

The 0F48155 is a 22TB WD Ultrastar DC HC570 3.5-inch internal enterprise HDD engineered for capacity-optimised storage nodes and JBOD shelves where predictable throughput and sustained 24x7 duty are mandatory. Designed for modern server platforms, the 0F48155 integrates cleanly into SATA backplanes and RAID controllers, providing a pragmatic path to high-density storage expansion without consuming additional PCIe lanes or introducing NVMe management overhead.

Architecturally, the 0F48155 combines 7200RPM mechanics with 512MB cache and Advanced Format support for 4Kn and 512e, enabling alignment with contemporary file systems and object storage layouts while maintaining compatibility for mixed environments. OptiNAND and ArmorCache improve metadata handling and write protection during power events, while ePMR and a Triple Stage Actuator support track-following precision at scale. For operational confidence, the 0F48155 targets 2.5M hours MTBF and includes Secure Erase for controlled decommissioning in regulated data centre workflows.

Why Choose the 0F48155?

The 0F48155 prioritises density-per-rack-unit and consistent serviceability for enterprise storage tiers, making it a practical building block for RAID arrays and software-defined storage where rebuild windows, fleet uniformity, and predictable power profiles matter. With OCP 2.0 alignment and proven 3.5-inch form factor integration, the 0F48155 scales from single-node expansion to multi-shelf deployments with standardised spares and operational procedures.

WD engineering focuses on reliability disciplines required for data centre duty, balancing high areal density with firmware control, qualification processes, and interoperability that align with common storage enclosures, controllers, and monitoring standards across enterprise environments.

Key Applications:

• Capacity-optimised storage nodes
• JBOD shelves and expansion enclosures
• Backup and archive tiers
• Object storage repositories
• Software-defined storage clusters
• RAID arrays in server platforms
