0B36020 WD Ultrastar DC HC310 4TB SAS 256 MB 3.5" Server HDD

Enterprise 3.5in SAS Data Center HDD featuring Self-Encrypting Architecture with the 0B36020

The 0B36020 is a WD Ultrastar DC HC310 4TB internal 3.5in SAS HDD engineered for predictable performance in shared storage pools and RAID arrays. As a 7.2K RPM, CMR-based drive with 256MB cache and 512n formatting, the 0B36020 is optimized for consistent write behavior, stable rebuild characteristics, and sustained throughput under mixed read/write server workloads.

Designed for SAS backplanes and enterprise controllers, the 0B36020 supports single-port SAS connectivity for straightforward integration into SAN/NAS expansion shelves and general-purpose datacenter HDD tiers. Its mechanical and firmware tuning aligns with 24x7 duty cycles, while the power profile helps manage thermals and density in multi-drive enclosures. For security-conscious environments, the 0B36020 implements Self-Encrypting Drive capabilities with TCG Enterprise SSC and FIPS 140-2 Level 2 support to simplify compliance-driven at-rest protection without introducing host CPU overhead.

Why Choose the 0B36020?

The 0B36020 delivers a balanced capacity-to-I/O profile for enterprise HDD layers where reliability, serviceability, and predictable RAID behavior matter more than peak IOPS. With a 2.0M-hour MTBF target and hardware-based encryption, the 0B36020 fits standardized fleet deployments that require scalable operations, consistent lifecycle management, and secure asset handling across racks and sites.

WD Ultrastar engineering emphasizes datacenter-grade validation, firmware stability, and interoperability with common SAS infrastructure, aligning the platform with modern reliability expectations for always-on storage tiers and controlled change management.
