High-Performance 3.5in Enterprise SAS Capacity HDD engineered for dense storage tiers with the 0F38528
The 0F38528 is a WD Ultrastar DC HC550 3.5in internal SAS hard drive designed for 24/7 data centre duty where predictable latency, sustained throughput, and high capacity per bay are required. Built on a 7200 RPM platform with 512MB cache, the 0F38528 targets capacity tiers in scale-out and object storage as well as bulk storage pools in virtualized and HCI environments.
To keep performance consistent under multi-drive concurrency, the 0F38528 combines EAMR with TDMR to maintain signal integrity at high areal density, supporting large RAID sets and rebuild scenarios. The SAS interface integrates cleanly into dual-ported enterprise backplanes and storage controllers, while 4Kn with 512e compatibility simplifies alignment planning across mixed OS and hypervisor stacks. Architectural features such as Rotational Vibration Safeguard with a triple-stage actuator help protect IOPS stability in dense rack enclosures where mechanical coupling and airflow profiles can otherwise impact seek accuracy.
Why Choose the 0F38528?
For capacity-centric designs, the 0F38528 delivers a strong density-to-performance balance that reduces rack footprint and power per TB without compromising operational continuity. With 2.5M hours MTBF and enterprise SAS integration, the 0F38528 supports scalable deployment across JBOD shelves and server bays, enabling consistent fleet behaviour for tiered storage, backup targets, and large datastore expansions.
WD engineers Ultrastar platforms for continuous workloads, emphasizing vibration tolerance, sustained duty operation, and predictable integration into modern data centre serviceability standards. The 0F38528 reflects this focus with mechanisms and firmware tuned for multi-drive environments and long lifecycle planning.
Key Applications:
- Scale-out and object storage capacity nodes
- RAID arrays and JBOD expansion shelves
- HCI and virtualization bulk datastores
- Backup-to-disk and archive tiers
- Log retention and compliance storage
At Happyware - Server Hardware you benefit from non-binding offers tailored to your capacity and RAID design, and the option to extend warranty coverage up to 6 years to align the 0F38528 deployment with long-term maintenance and lifecycle requirements.
