0B36402 WD Ultrastar DC HC320 8TB SATA 256 MB 3.5" Server HDD

Capacity-Tier 3.5in Enterprise SATA HDD for RAID and Datacenter Storage with the 0B36402

The 0B36402 is a WD Ultrastar DC HC320 8TB internal 3.5in SATA HDD engineered for capacity-focused server storage tiers where predictable latency and sustained throughput matter more than flash-class IOPS. Designed for 24/7 operation in general-purpose servers and SATA shelves, the 0B36402 supports always-on file services, virtualization storage pools, and scale-out backup targets with consistent behavior under multi-drive RAID workloads.

Architecturally, the 0B36402 combines 7200 RPM mechanics with a 256MB cache to stabilize burst absorption and write coalescing when controllers are balancing parity calculations. Using CMR recording, it avoids the write amplification patterns associated with SMR drives, making the 0B36402 suitable for rebuild-intensive RAID arrays and mixed read/write duty cycles. Its 4Kn native sector format aligns with modern OS and storage stacks for efficient metadata handling and reduced translation overhead, while standard SATA connectivity keeps expansion flexible across common HBAs and backplanes.

Why Choose the 0B36402?

The 0B36402 delivers a practical density-to-reliability profile for enterprises standardizing on SATA capacity tiers, enabling predictable scaling in multi-bay arrays without introducing interface complexity. With a 2.0M-hour MTBF design target and datacenter duty cycle focus, the 0B36402 supports repeatable deployment patterns for bulk storage growth, RAID resiliency planning, and controlled lifecycle refresh in rack and shelf architectures.

WD designs Ultrastar datacenter drives with an engineering emphasis on continuous availability, controlled acoustics and power behavior, and compatibility with established server and storage qualification processes, aligning the platform with modern operational standards for monitored, always-on infrastructure.

Key Applications:

• RAID arrays for capacity tiers
• Always-on file and print services
• Backup repositories
• Archive and retention storage
• SATA JBOD and storage shelves
