0B48608 WD Ultrastar DC HA340 12TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for capacity tiers and RAID arrays with the 0B48608

The 0B48608 is a 12TB WD Ultrastar DC HA340 internal enterprise HDD designed for 24x7 data center duty cycles where predictable throughput and sustained integrity matter more than peak IOPS. As a 3.5in, 7200RPM CMR drive on a SATA host bus, it aligns with widely deployed server backplanes and storage shelves, enabling consistent write behavior under RAID rebuilds and long sequential streams.

Architecturally, the 0B48608 supports capacity-focused tiers by combining a large cache and stable rotational characteristics with operational safeguards that mitigate vibration and shock in dense chassis. 4Kn media with 512e emulation simplifies interoperability with existing operating systems, controllers, and virtualization stacks while keeping sector alignment manageable during migrations. This makes the 0B48608 a practical building block for bulk storage pools, backup repositories, and archival targets where expansion slots and PCIe lanes are reserved for compute or NVMe acceleration rather than capacity.

Why Choose the 0B48608?

The 0B48608 delivers a strong density-to-bay ratio in standard 3.5in platforms, helping architects scale raw capacity per rack without introducing new enclosure standards. With an enterprise MTBF target and firmware tuned for array environments, the 0B48608 supports consistent fleet behavior, predictable service windows, and straightforward lifecycle planning across multi-drive deployments.

WD engineers Ultrastar enterprise HDDs for continuous operation, controlled acoustics and vibration tolerance, and alignment with modern data center qualification practices. The 0B48608 reflects this focus through rotational vibration protection, dynamic fly height control, and sensor-based safeguards that help maintain reliability in shared-chassis storage.

Key Applications:

• Server bulk storage
• RAID arrays and rebuild-intensive tiers
• Backup repositories
• Archival and capacity-focused storage pools
• Scale-out object storage nodes
