HUS724020ALS640 WD Ultrastar 7K4000 2TB SAS 64 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for 24x7 RAID and Capacity Tiers with the HUS724020ALS640

The HUS724020ALS640 is a 3.5in internal enterprise HDD designed for server boot/media roles and general-purpose capacity where predictable latency and consistent throughput are required. In CPU-dense rack platforms and storage shelves, the HUS724020ALS640 complements modern compute nodes by offloading bulk data and log retention from NVMe tiers while keeping a familiar SAS management model for fleet operations.

For infrastructure built around multi-core CPU generations with high memory bandwidth, the HUS724020ALS640 enables cost-effective scaling of persistent datasets without consuming PCIe lanes needed for GPUs, NICs, or NVMe expansion. Its 512n sector format supports legacy OS images and boot environments, while CMR recording and 7200 RPM operation provide stable RAID behavior in controller-backed arrays, SAN/NAS capacity tiers, and transactional service partitions.

Why Choose the HUS724020ALS640?

The HUS724020ALS640 delivers an enterprise reliability profile aligned with continuous datacentre duty cycles and RAID rebuild demands. As a 2TB SAS HDD, it supports straightforward density planning in 3.5in bays, consistent serviceability in hot-swap backplanes, and scalable deployment across homogeneous storage pools where operational standardization matters.

WD engineers the Ultrastar platform for controlled vibration environments, sustained workloads, and predictable failure characteristics that simplify spares strategy. With enterprise qualification focus and interoperability in SAS ecosystems, the HUS724020ALS640 aligns with modern data centre requirements for availability, manageability, and long-term lifecycle continuity.
