0B28990 WD Ultrastar C15K600 0.45TB SAS 128 MB 2.5" Server HDD

High-Performance 2.5in SAS Enterprise HDD for mixed-tier arrays with the 0B28990

The 0B28990 is a WD/HGST Ultrastar C15K600 2.5in internal SAS enterprise HDD engineered for consistent low-latency I/O in legacy and modern storage shelves where predictable performance per slot matters. As a 15K RPM class drive with CMR recording and a 128MB cache, the 0B28990 supports sustained transactional access patterns typical of shared infrastructure and RAID disk groups.

Designed for SAS backplanes and enterprise controllers, the 0B28990 integrates cleanly into PCIe-based server platforms through standard SAS HBAs and RAID adapters, enabling straightforward expansion without introducing SSD qualification constraints. Its 512B native (512n) sector format targets compatibility-driven environments and simplifies replacement cycles in 512n arrays, reducing the need for reformatting or mixed-sector mitigations. With Self-Encrypting Drive (SED) capability using TCG Enterprise SSC, the 0B28990 provides hardware-based data-at-rest protection while maintaining stable throughput. A 24x7 duty-cycle and 2.0M hours MTBF align the drive with continuous operation requirements in dense chassis where power and thermals must remain controlled.

Why Choose the 0B28990?

The 0B28990 delivers a balanced density-to-performance profile for SAS HDD refresh projects, providing deterministic spindle-based I/O for RAID sets and mixed-tier arrays while preserving operational consistency. Its enterprise reliability characteristics support scalable deployments across multiple disk groups with predictable behavior under sustained load.

WD’s Ultrastar engineering emphasizes controlled firmware behavior, qualification for continuous data center duty cycles, and long-life mechanical design. The platform targets standards-aligned integration into SAS infrastructure with security and compatibility considerations appropriate for enterprise retention and governance models.

Key Applications:

• SAS HDD replacement in existing arrays
• RAID disk groups for transactional workloads
• Mixed-tier storage pools and caching tiers
• Security-conscious data-at-rest environments
• 512n legacy compatibility deployments
