0B47743

High-Density 3.5" Enterprise SAS HDD for 24x7 Datacenters with the 0B47743

The 0B47743 is a 14TB 3.5" internal enterprise HDD engineered for capacity tiers in servers and storage arrays where predictable latency and sustained throughput matter more than peak IOPS. Built on a 7200RPM platform with 512MB cache, it aligns with modern HBA and RAID controller designs using a single-port SAS interface for consistent multipath-free integration in scale-out shelves and traditional SAN/JBOD topologies.

For data integrity and host compatibility, the 0B47743 uses 4Kn sector format with 512e emulation to support both newer operating environments and legacy stacks during migration. CMR recording with ePMR/EAMR, TDMR, and a triple-stage actuator improves track control under enterprise workloads, while HelioSeal and RV sensors help maintain performance stability in dense enclosures. This architecture is optimized for bulk data, log retention, and cold-to-warm datasets where capacity efficiency and operational continuity drive design decisions.

Why Choose the 0B47743?

The 0B47743 delivers a pragmatic density-to-performance profile for always-on repositories, enabling higher usable capacity per rack unit while keeping integration straightforward across SAS backplanes and standard RAID policies. With an enterprise reliability target of 2.5M hours MTBF, the 0B47743 supports scalable growth strategies for backup, archival, and large file/object stores without forcing a change in storage architecture or operational processes.

Western Digital designs the Ultrastar platform around datacenter duty cycles, focusing on mechanical stability, thermal behavior, and qualification practices that align with 24x7 environments and common storage-array validation standards.

Key Applications:

Capacity tier for servers and storage arrays
Backup and archival repositories
Large-scale object and file storage
Log retention and compliance datasets
Cold-to-warm data pools
