High-Density 3.5in Enterprise SAS HDD for data centre bulk storage with the 0F38353
The 0F38353 is a WD Ultrastar DC HC550 18TB 3.5in internal enterprise HDD engineered for SAS-connected storage tiers where predictable latency, sustained throughput, and continuous duty cycles matter more than peak IOPS. Designed for scale-out file and object platforms as well as dense RAID shelves, the 0F38353 supports single-port SAS connectivity and 512e sector formatting to align with modern controllers while maintaining broad legacy compatibility.
Architecturally, the 0F38353 focuses on capacity-per-slot and stable performance under long sequential streams and mixed read/write patterns typical of rebuilds and background scrubbing. EAMR paired with TDMR improves areal density and head positioning accuracy to keep performance consistent at high platter densities. A 7200RPM spindle and 512MB cache help absorb burst activity and reduce host backpressure during queue transitions, while the 512e format enables controlled migration paths toward 4Kn strategies without forcing immediate end-to-end changes.
Why Choose the 0F38353?
The 0F38353 delivers a strong density-to-rack-unit ratio for enterprise storage pools, enabling fewer drives per usable PB and simplifying enclosure planning, power budgets, and spares strategy. With a 2.5M-hour MTBF profile and 24x7 duty-cycle alignment, the 0F38353 is suited to standardized fleet deployments where operational continuity, predictable maintenance windows, and scalable capacity expansion are core requirements.
WD engineers the Ultrastar platform with a focus on data centre reliability, vibration-aware mechanics, and firmware behaviors optimized for RAID and storage enclosure environments. The 0F38353 aligns with modern enterprise standards for SAS integration, sector-format interoperability, and sustained operation across mixed workload storage tiers.
Key Applications:
- Scale-out file and object storage
- Data centre bulk capacity tiers
- RAID arrays in servers and storage enclosures
- Backup and archive repositories
- Distributed storage nodes
At Happyware - Server Hardware you benefit from non-binding offers tailored to your rollout plans for the 0F38353 and the option to extend the warranty up to 6 years for additional investment security in long-lived storage tiers.
