0B48722

High-Capacity 3.5-inch Datacenter HDD featuring CMR nearline storage efficiency with the 0B48722

The 0B48722 is a WD Ultrastar DC HC555 16TB internal 3.5-inch enterprise HDD engineered for predictable throughput and consistent latency in SATA-based storage tiers. In server and JBOD architectures, the 0B48722 supports capacity-focused pools where controller CPU and cache manage IO aggregation while the drive delivers stable sequential performance at 7200RPM with a 512MB cache.

Designed for modern storage backplanes, the 0B48722 integrates cleanly into PCIe-attached HBAs and RAID adapters through its SATA interface, enabling straightforward expansion across dense enclosures. Its 4Kn native format with 512e emulation supports alignment with contemporary operating systems and filesystems, while CMR media with EAMR helps maintain write determinism for rebuilds and sustained ingest. For 24x7 duty cycles, the 0B48722 combines RV sensors and a triple-stage actuator to reduce vibration-induced performance variance in multi-drive chassis.

Why Choose the 0B48722?

The 0B48722 is optimized for high TB-per-rack deployments where cost-efficient capacity and operational consistency matter more than IOPS density. With 2.5M hours MTBF, it aligns to enterprise reliability targets for scale-out growth, simplifying lifecycle planning across nearline primary storage, backup repositories, and retention tiers while keeping power draw controlled in large drive counts.

WD designs Ultrastar platforms with a focus on datacenter integration, emphasizing mechanical stability, firmware behavior tuned for RAID/JBOD environments, and compatibility with standardized 3.5-inch service models used across modern data centre operations.

Key Applications:

Nearline capacity tiers in rack servers and JBOD shelves
Disk-based backup repositories
Archive and retention storage
Object storage platforms
Distributed file systems

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your needs for integrating the 0B48722 into existing storage shelves or new capacity builds, and can extend the warranty up to 6 years to protect long-term deployments.
