0B35914 WD Ultrastar DC HC310 6TB SAS 256 MB 3.5" Server HDD

Enterprise 3.5in SAS Datacenter HDD for capacity-tier storage with the 0B35914

The 0B35914 is a WD Ultrastar DC HC310 3.5in internal enterprise HDD engineered for SAS backplanes where predictable latency, sustained throughput, and serviceable density are required for bulk storage tiers. In capacity-optimised pools, the 7200 RPM spindle and 256MB cache support consistent rebuild behavior and steady queue performance under mixed read/write server profiles.

Designed around a single-port SAS interface and 4Kn sector format, the 0B35914 aligns with modern controller stacks and RAID implementations that benefit from native 4K alignment and reduced write amplification compared with emulated formats. CMR recording provides stable performance characteristics under continuous operation, while the 6TB form factor enables balanced capacity-per-slot planning across enclosures without disrupting existing 3.5in chassis thermals and airflow models. For data governance requirements, the 0B35914 integrates Secure Erase and self-encrypting drive functionality to support secure lifecycle handling in shared datacenter environments.

Why Choose the 0B35914?

The 0B35914 is a practical building block for scalable SAS storage tiers where operational predictability matters more than peak metrics. Its datacenter-class design supports high drive counts in RAID arrays, delivering a dependable density-to-performance ratio for general-purpose storage pools, log repositories, and backup staging, while maintaining enterprise duty-cycle expectations for 24x7 deployments.

WD builds Ultrastar platforms with an engineering focus on long service life, controlled vibration behavior in multi-drive environments, and consistent qualification for enterprise backplanes. This approach aligns with standard datacenter operational models, including structured maintenance windows, secure decommissioning, and capacity growth through incremental shelf expansion.

Key Applications:

• SAS RAID arrays and JBOD shelves
• Bulk capacity tiers for virtualisation clusters
• Backup repositories and archive staging
• Log, telemetry, and audit data retention
