0F38527 WD Ultrastar DC HC550 14TB SAS 512 MB 3.5" Server HDD

High-Density 3.5in SAS Enterprise Datacenter HDD featuring helium EAMR/TDMR recording with the 0F38527

The 0F38527 is a 14TB 3.5in SAS 7,200 RPM enterprise HDD engineered for scale-out bulk storage, RAID arrays, and SAN/NAS disk shelves where predictable latency and sustained throughput matter more than peak IOPS. Its 512 MB cache and SAS interface integrate cleanly into dual-controller backplanes and expander topologies, supporting resilient multi-path access and standardized management across heterogeneous storage nodes.

Designed for 24x7 duty cycles, the 0F38527 uses a helium-filled platform with EAMR and TDMR to increase areal density while maintaining read-channel integrity as capacities scale. Support for 4Kn with 512e flexibility helps align sector formats to modern filesystems and RAID implementations, reducing translation overhead during rebuilds and scrubs. For regulated environments, the integrated TCG Enterprise SSC self-encrypting drive capability enables at-rest protection that can be centrally managed without introducing software-layer performance variability.

Why Choose the 0F38527?

The 0F38527 provides an enterprise-optimized density-to-power profile for capacity tiers, enabling higher usable TB per rack unit while controlling operational watts across large drive counts. With a 2.5M-hour MTBF design target and SAS interoperability for multi-path deployments, the 0F38527 scales reliably in RAID and erasure-coded pools, supporting consistent service levels during background maintenance, rebuild events, and continuous operation.

WD engineers the Ultrastar datacenter portfolio with a focus on long-life mechanics, firmware tuned for array behavior, and compatibility with established SAS storage standards to simplify qualification in modern data center architectures.

Key Applications:

• Datacenter bulk storage tiers
• RAID arrays and rebuild-intensive pools
• Backup and archive repositories
• SAN/NAS HDD expansion shelves
• Scale-out object and file storage nodes
