HUS153030VLS300 WD Ultrastar 15K300 0.3TB SAS 16 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for 24x7 Tiered Storage with the HUS153030VLS300

The HUS153030VLS300 is an internal enterprise HDD engineered for SAS backplanes in rack servers and storage arrays where predictable latency and sustained IOPS matter more than capacity density. As a 15K-class Ultrastar platform drive, it aligns with CPU-bound and transaction-heavy architectures by reducing storage wait states for OS, boot, and log tiers, keeping host resources focused on application execution rather than queue depth management.

With CMR recording and a single SAS interface, the HUS153030VLS300 integrates cleanly into dual-controller enclosures and expander-based SAS topologies, supporting deterministic behavior under mixed read/write patterns. The 16MB cache is tuned for command coalescing and write management in enterprise workloads, while its 3.5in design supports straightforward serviceability in hot-swap carriers. Power characteristics are optimized for continuous operation, enabling stable thermal planning in dense chassis and drive shelves.

Why Choose the HUS153030VLS300?

The HUS153030VLS300 provides a balanced density-to-performance profile for organizations standardizing a SAS HDD tier across enterprise servers and storage arrays. It is designed for 24x7 duty cycles, supports scalable deployment across multi-bay backplanes, and fits operational models where consistent performance, controlled acoustics/thermals, and predictable maintenance windows are required.

WD’s Ultrastar engineering emphasizes reliability under sustained utilization, firmware behavior suited to enterprise error handling, and mechanical tolerances built for continuous vibration and duty-cycle demands. The HUS153030VLS300 reflects this focus with a design aligned to modern data centre serviceability practices and long-lived SAS infrastructure.

Key Applications:

• SAS HDD tier for enterprise servers and storage arrays
• OS and boot volumes on SAS backplanes
• Database log, journal, and metadata volumes
• Legacy SAN/NAS environments with SAS drive shelves
