0B36042 WD Ultrastar DC HC310 6TB SATA 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SATA HDD for Datacenter Storage Tiers with the 0B36042

The 0B36042 is a WD Ultrastar DC HC310 3.5in SATA datacenter hard drive engineered for predictable throughput and sustained 24x7 operation in scale-out storage nodes. It targets bulk storage tiers where consistent latency behavior, robust firmware controls, and long duty cycles matter more than peak IOPS, making the 0B36042 a practical building block for enterprise capacity pools.

Using 7200 RPM CMR recording with 4Kn (512e) sector formatting and a 256MB cache, the 0B36042 supports sequential-heavy and mixed read/write workloads typical of backup repositories and object storage landing zones. Its SATA interface enables broad platform compatibility and dense expansion behind HBAs and storage controllers, while the drive’s architecture aligns with high-bay JBOD designs, RAID groups, and erasure-coded storage where rebuild reliability and error recovery behavior are critical.

Why Choose the 0B36042?

The 0B36042 delivers a balanced density-to-performance profile for capacity-oriented arrays, pairing enterprise endurance and a 2.0M-hour MTBF with operational consistency across large drive counts. The 0B36042 also simplifies scalable rollouts in standardized 3.5in bays, enabling predictable capacity growth without redesigning host platforms or storage shelves.

WD designs Ultrastar datacenter drives around reliability engineering, controlled firmware behavior, and integration with modern rack and storage architectures. With the 0B36042, WD focuses on continuous-operation requirements, validated workload profiles, and long lifecycle alignment to enterprise procurement and qualification processes.

Key Applications:

• Scale-out storage nodes and JBOD shelves
• Backup targets and restore repositories
• Archive and secondary storage pools
• Compliance-focused self-encrypting deployments
