HUA722010CLA330 WD Ultrastar A7K2000 1TB SATA 32 MB 3.5" Server HDD

Enterprise 3.5in SATA HDD for Reliable Capacity Tiers with the HUA722010CLA330

The HUA722010CLA330 is a 3.5in internal enterprise HDD designed to deliver predictable, always-on storage behavior in SATA server backplanes and storage arrays. As part of a tiered architecture, it provides a stable 1TB capacity point for OS volumes, log repositories, and bulk data pools where cost-efficient magnetic media and consistent latency characteristics are required.

With 7200 RPM mechanics and CMR recording, the HUA722010CLA330 supports steady write performance under mixed workloads and avoids the write-amplification side effects common to SMR designs. Integration is straightforward in standard SATA controllers and expanders, and the 4Kn (512e) sector format helps align with modern OS and RAID configurations for efficient block management. The 32MB cache assists with command queue smoothing and burst handling, while power profiles (3.9W idle, 8.4W active) support denser deployments without over-allocating rack-level power budgets.

Why Choose the HUA722010CLA330?

The HUA722010CLA330 fits enterprise environments that prioritize deterministic behavior and serviceability over peak IOPS, enabling clean separation of performance tiers and capacity tiers. It scales efficiently across multi-drive arrays, supports 24/7 duty cycles, and provides a pragmatic density-to-performance balance for SATA-based platforms where operational stability and predictable rebuild behavior are key.

WD engineering emphasizes lifecycle consistency, controlled component qualification, and reliability practices aligned with modern data centre expectations. This focus supports sustained operation in servers and storage systems that demand continuous availability, repeatable acoustics/thermals, and straightforward fleet management.

Key Applications:

• Boot and OS volumes
• Log and audit retention
• General-purpose file storage tiers
• Backup staging and repositories
• Archive and bulk data pools
