0B36404

High-Performance 3.5in Enterprise SATA HDD featuring CMR bulk capacity with the 0B36404

The 0B36404 is an 8TB 3.5in internal enterprise HDD designed for predictable throughput and consistent latency in always-on storage tiers. With 7200 RPM mechanics, CMR recording, and a SATA interface aligned to common rack server backplanes, the 0B36404 fits cleanly into mixed-vendor fleets where capacity density and serviceability drive platform decisions.

Architecturally, the 0B36404 supports 4Kn media with 512e emulation to ease migration across operating systems, RAID controllers, and legacy partitioning constraints while keeping sector handling consistent for modern filesystems. A 256MB cache helps absorb bursty metadata and write coalescing, and hardware encryption support enables policy-driven data protection without relying solely on host CPU cycles. For expansion planning, the 0B36404 is well suited to scale-out JBOD shelves, entry storage arrays, and server-based storage where SATA lane availability and bay density define the effective $/TB and watts/TB profile.

Why Choose the 0B36404?

The 0B36404 provides a balanced density-to-performance ratio for tier-2 pools, backup repositories, and capacity-focused RAID groups, combining enterprise duty-cycle operation with deployment simplicity. Its high MTBF class and 24x7 design target reliable fleet operation, while the standardized 3.5in SATA form factor supports straightforward spares management and consistent scaling across racks and sites.

WD engineers Ultrastar platforms for sustained data centre workloads, emphasizing controlled vibration tolerance, predictable error recovery behavior, and long-life reliability characteristics aligned with modern server and storage qualification processes. The result is an enterprise HDD profile that integrates cleanly into monitoring, lifecycle management, and secure data handling standards.
