0B36411 WD Ultrastar DC HC320 8TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in SAS Data Center HDD featuring secure 4Kn CMR recording with the 0B36411

The 0B36411 is an internal WD Ultrastar DC HC320 8TB 3.5in SAS HDD engineered for capacity-oriented datacenter platforms where predictable latency, deterministic sector formatting, and continuous duty cycles are mandatory. Designed for SAS backplanes and storage controllers, the 0B36411 integrates cleanly into existing JBOD and RAID enclosures, supporting streamlined replacement and expansion without disrupting established operational procedures.

Architecturally, the 0B36411 targets scale-out file and object storage nodes that depend on efficient sequential throughput and stable performance under sustained queue depth. Its 4Kn format reduces translation overhead in modern storage stacks, while CMR recording supports consistent write behavior compared with shingled approaches. The 7200 RPM mechanism and onboard cache help smooth bursty I/O patterns typical of metadata activity and rebuild operations. For security-sensitive deployments, the 0B36411 provides self-encrypting drive capability aligned to TCG Enterprise SSC and FIPS 140-2 Level 2 requirements, enabling encryption at rest without consuming host CPU cycles.

Why Choose the 0B36411?

The 0B36411 delivers a balanced density-to-serviceability profile for enterprise SAS infrastructures, pairing 8TB capacity with 24x7 datacenter reliability and a controller-friendly 4Kn/CMR design. The 0B36411 is well suited for scaled deployments where predictable behavior during RAID rebuilds, consistent firmware management, and long-life operational planning are critical to uptime and maintenance efficiency.

WD engineers the Ultrastar portfolio for sustained datacenter workloads, emphasizing validation under continuous operation, controlled acoustics and power behavior, and compatibility with modern server and storage-array standards. With the 0B36411, WD combines enterprise SAS integration with proven capacity engineering and hardware-based data protection aligned to regulated environments.
