High-Density 3.5in Datacenter SAS HDD for Capacity Storage featuring the 0B47747
The 0B47747 is a WD Ultrastar DC HC555 18TB 3.5in enterprise HDD engineered for always-on datacenter environments where predictable latency, sustained throughput, and RAID-friendly behavior are critical. Designed for capacity-tier platforms rather than compute acceleration, the 0B47747 integrates a 12Gb/s SAS interface to fit modern server backplanes and storage shelves while maintaining consistent integration across mixed-drive fleets.
Architecturally, the 0B47747 targets scale-out storage and dense JBOD/RAID designs where rebuild times, vibration tolerance, and controller interoperability determine operational stability. ePMR with TDMR supports high areal density for bulk datasets, while a 512MB cache and 7200RPM profile help sustain sequential performance for backup repositories and object/file nodes. 512e sector formatting provides broad compatibility with enterprise OS and RAID stacks, simplifying migration planning across legacy and 4Kn-aligned environments.
Why Choose the 0B47747?
The 0B47747 is optimized for maximizing terabytes per rack unit without sacrificing datacenter reliability, making it a practical standard drive for capacity nodes and shared storage pools. With a 24x7 duty cycle design, rotational vibration sensors, and a triple-stage actuator, the 0B47747 supports higher bay counts and predictable performance under multi-drive vibration, improving scalability for growing arrays.
WD engineers Ultrastar platforms for sustained enterprise duty cycles, focusing on mechanical stability, tight tolerance head positioning, and lifecycle consistency aligned with modern datacenter qualification processes and SAS infrastructure standards.
Key Applications:
- Backup and restore repositories
- Archive and bulk data lakes
- Scale-out file and object storage
- SDS and HCI capacity nodes
- RAID arrays and JBOD expansion shelves
At Happyware - Server Hardware you benefit from non-binding offers tailored to your storage architecture and procurement model, and you can extend the warranty up to 6 years to align the 0B47747 deployment with your operational risk and lifecycle plans.
