0B35950

High-Performance 3.5in Enterprise SATA HDD storage with capacity-optimised CMR engineering using the 0B35950

The 0B35950 is a 3.5in Western Digital Ultrastar DC HC310 enterprise HDD designed for capacity-oriented internal storage tiers where predictable latency and long-duty-cycle operation matter more than peak IOPS. Built around a 7200RPM CMR recording method and 512n sector format, the 0B35950 integrates cleanly into standard SATA backplanes in rack servers and storage nodes, supporting consistent write behaviour for logs, backups, and cold data archives.

In mixed server architectures, the 0B35950 complements NVMe and SSD tiers by offloading sequential and retention-heavy datasets, reducing cost per TB without compromising operational stability. With a 256MB cache and SATA interface compatibility, the 0B35950 is suited for broad controller interoperability, while its 24/7 design target and 2.0M-hour MTBF align with always-on datacentre maintenance windows and fleet-level reliability planning.

Why Choose the 0B35950?

The 0B35950 delivers an efficient density-to-performance balance for enterprises standardising on SATA HDD tiers for secondary storage, boot/archive partitions, or bulk repositories. The 0B35950 supports scalable deployment across homogeneous drive pools, enabling predictable rebuild and retention strategies, and it fits operational models that prioritise controlled power profiles, serviceability, and consistent CMR write characteristics.

Western Digital’s Ultrastar engineering focuses on predictable enterprise operation, validated compatibility, and reliability metrics aligned with modern data centre standards. With support for Secure Erase and an architecture tuned for continuous workloads, this platform is designed to integrate into disciplined lifecycle management and compliance-driven decommissioning processes.

Key Applications:

Server boot and archive volumes
Backup repositories and retention tiers
Log aggregation and audit trails
General-purpose SATA storage pools
Cold data and nearline archives

At Happyware - Server Hardware you benefit from non-binding offers tailored to your storage architecture and rollout plan, plus bulk order discount options for standardising the 0B35950 across larger server and storage deployments.
