0B42258 WD Ultrastar DC HC330 10TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SAS HDD for JBOD and RAID Capacity Expansion with the 0B42258

The 0B42258 is a WD Ultrastar DC HC330 10TB 3.5in SAS hard drive engineered for predictable performance and fleet-scale serviceability in always-on storage tiers. Designed to integrate cleanly into SAS backplanes, expanders, and dual-controller shelves, the 0B42258 supports consistent throughput for sequential workloads while maintaining compatibility through 512e formatting options for mixed legacy and modern environments.

For systems engineers building capacity within JBODs and RAID shelves, the 0B42258 uses CMR recording to sustain stable write behavior under continuous ingestion, avoiding the variability often seen in write-rewrite workflows. A 7200RPM spindle and cache architecture provide responsive access for backup repositories and log-heavy platforms, while multi-drive chassis operation is supported through rotational vibration sensing to reduce performance deviation as enclosure density increases. Security features such as SED support and Secure Erase enable lifecycle control aligned to enterprise decommissioning processes.

Why Choose the 0B42258?

The 0B42258 delivers an efficient density-to-bay ratio for SAS capacity pools where reliability and predictable rebuild behavior matter. It fits deployment models that scale horizontally across many spindles, supporting high-availability architectures with consistent operational characteristics across 24/7 duty cycles and large RAID groups, while simplifying standardization for procurement and spares.

WD designs Ultrastar datacenter drives with a focus on mechanical stability, qualification discipline, and interoperability across common enterprise SAS storage platforms. The engineering approach prioritizes controlled acoustics, vibration tolerance, and long-life operation to meet modern data center expectations for continuous service.

Key Applications:

• SAS JBOD capacity expansion
• RAID shelf bulk storage tiers
• Backup and recovery repositories
