WUS721010AL5204 WD Ultrastar DC HC330 10TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Datacenter SAS HDD for Scale-Out Storage with the WUS721010AL5204

The WUS721010AL5204 is a 10TB, 3.5in datacenter-class enterprise HDD engineered for predictable throughput and consistent latency in bulk storage tiers where capacity efficiency and uptime are primary design constraints. As a 7,200 RPM CMR drive on 12Gb/s SAS, it integrates cleanly into modern server and storage backplanes, supporting dual-ported SAS paths for resilient connectivity and controller failover in enterprise enclosures.

Architecturally, WUS721010AL5204 targets capacity-heavy RAID groups and scale-out nodes where PCIe lanes are reserved for compute accelerators, NICs, or NVMe tiers, while HDD pools deliver economical persistence. The 4Kn format with 512e compatibility simplifies alignment in mixed environments, and a 256MB cache supports sustained streaming patterns typical of backup windows and sequential ingest. Secure Erase (SE) enables operationally safe decommissioning workflows without disrupting established storage management processes, making WUS721010AL5204 suitable for regulated lifecycle handling.

Why Choose the WUS721010AL5204?

The WUS721010AL5204 provides an effective density-to-reliability profile for 24/7 duty cycles, delivering enterprise SAS integration for large RAID sets and distributed storage nodes where service continuity matters more than peak IOPS. With a 2.0M-hour MTBF design point, WUS721010AL5204 supports scalable deployments that standardize on proven HDD architecture for predictable capacity expansion.

WD’s Ultrastar engineering focuses on datacenter qualification, consistent firmware behavior, and long-life mechanical design aligned with rack-scale operational standards, helping reduce variability across high-drive-count environments.

Key Applications:

• Data center bulk storage
• RAID arrays and JBOD expansion
• Backup and archive tiers
• Scale-out storage nodes
• Virtualization datastore capacity growth
