0B36015 WD Ultrastar 6TB SAS 256 MB 3.5" Server HDD

Enterprise 3.5-inch Datacenter SAS HDD for 24x7 Capacity Tiers with the 0B36015

The 0B36015 is a 3.5-inch, 6TB datacenter HDD engineered for SAS backplanes in JBOD shelves and RAID arrays where predictable performance and operational continuity matter. Built on CMR recording with 7200 RPM mechanics and a 256MB cache, the 0B36015 delivers stable latency characteristics for rebuild-sensitive pools and capacity-focused virtualization and file services.

With a 4Kn sector format, the 0B36015 aligns well with modern storage stacks that standardize on native 4KB blocks to reduce translation overhead and improve capacity efficiency at scale. The SAS interface supports dual-port enterprise connectivity and streamlined integration into scale-out storage nodes, while the drive’s 24/7 duty design and 2.0M-hour MTBF profile target always-on backup, archive, and secondary tiers that still require datacenter-class reliability. For regulated environments, the 0B36015 also supports Self-Encrypting Drive deployments with TCG Enterprise SSC, enabling policy-driven data-at-rest controls.

Why Choose the 0B36015?

The 0B36015 provides a pragmatic density-to-reliability balance for capacity pools where fleet consistency and serviceability drive total cost of ownership. By standardizing on the 0B36015 across shelves and nodes, infrastructure teams can simplify qualification, maintain predictable RAID behavior, and scale storage footprints while keeping enterprise operational requirements in focus.

WD designs Ultrastar-class drives around sustained datacenter workloads, emphasizing mechanical durability, firmware behavior tuned for multi-drive environments, and compatibility with common SAS storage architectures. This engineering approach supports long service life in modern racks and aligns with operational standards for continuous monitoring and lifecycle management.

Key Applications:

• SAS JBOD and RAID capacity arrays
• Backup and archive tiers
• Scale-out object and file storage nodes
• Bulk capacity for virtualization and file services
• Self-encrypting drive (SED) compliance deployments
