0B47076
Enterprise 3.5-inch SATA HDD engineered for secure bulk storage with the 0B47076
The 0B47076 is a WD Ultrastar DC HA340 4TB internal 3.5-inch enterprise HDD designed for predictable throughput and capacity-oriented tiers in servers and entry storage arrays. With a 7200RPM spindle and 256MB cache, the 0B47076 supports steady sequential performance while maintaining consistent latency behavior suited to shared infrastructure.
Built on CMR recording and 512e sector formatting, the 0B47076 aligns with mainstream SATA backplanes and broad OS compatibility, reducing integration friction in mixed fleets. The single-drive SATA interface supports standard HBA and RAID controller architectures, while enterprise mechanics such as a dual-stage actuator and rotational vibration compensation help preserve performance in dense multi-bay chassis. Hardware self-encrypting drive (SED) functionality adds at-rest protection without relying on host CPU cycles, supporting compliance-driven environments and secure decommissioning workflows.
Why Choose the 0B47076?
The 0B47076 provides a balanced density-to-reliability profile for capacity tiers where cost per TB, predictable service life, and operational consistency matter more than peak IOPS. Its 24x7 duty cycle design and 2.0M-hour MTBF target continuous operation in rack servers and storage shelves, enabling scalable pools for backups, archives, and cold VM datasets without complicating controller, cabling, or airflow planning.
WD engineers the Ultrastar portfolio around data centre duty cycles, controlled vibration behavior, and long-term fleet manageability. The platform is aligned with standard SATA infrastructure and maintenance practices, supporting consistent qualification in enterprise change-control processes and minimizing operational risk during refresh cycles.
Key Applications:
- Bulk capacity tiers in rack servers
- Backup and archive repositories
- File and print storage
- VM cold data and templates
- Log and telemetry retention
At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your capacity planning and RAID layout, and you can extend the warranty up to 6 years to match enterprise refresh and retention timelines for the 0B47076.
