0B36043 WD Ultrastar DC HC310 4TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in SATA Datacenter HDD for 24/7 RAID Storage Nodes with the 0B36043

The 0B36043 is a 3.5in WD Ultrastar DC HC310 enterprise HDD designed for predictable bulk storage performance in rack servers, disk shelves, and workstation-class storage nodes. Built around CMR recording and 7200 RPM mechanics, the 0B36043 targets sustained throughput and stable latency under concurrent read/write workloads typical of RAID groups and shared storage pools.

For platform integration, the 0B36043 connects via SATA, enabling broad compatibility across standard backplanes, HBA ports, and storage controllers while keeping PCIe lanes available for accelerators and high-speed networking. With 256MB cache and support for 4Kn sector format with 512e emulation, the 0B36043 helps architects align logical block sizing to modern filesystems and controller requirements, simplifying mixed-generation deployment and capacity expansion strategies across dense SATA shelves.

Why Choose the 0B36043?

The 0B36043 is engineered for enterprise duty cycles where density-to-performance consistency and operational predictability matter more than burst metrics. With a 24/7 design profile and 2.0M hours MTBF, the 0B36043 supports scalable RAID layouts and tiered storage designs that demand controlled failure domains, repeatable rebuild behavior, and fleet-wide standardization for capacity growth.

WD’s Ultrastar engineering focuses on datacenter reliability, qualification discipline, and interoperability with common server and storage ecosystems. This approach aligns the drive with modern data centre operational standards, including continuous operation, serviceability expectations, and security practices for managed infrastructure.

Key Applications:

• 24/7 RAID storage nodes
• High-density SATA disk shelves
• Backup and archive repositories
• Bulk storage for rack servers
• Capacity expansion in workstations
