HUS724040ALE641 WD Ultrastar 7K4000 4TB SATA 64 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SATA HDD featuring CMR durability and vibration tolerance with the HUS724040ALE641

The HUS724040ALE641 is a capacity-optimised 3.5in enterprise HDD engineered for 24/7 server duty where predictable throughput, controlled latency, and RAID behaviour matter more than peak IOPS. As a SATA tier drive, it integrates cleanly into mainstream x86 server platforms and storage controllers, supporting dense multi-bay chassis designs and simplifying fleet standardisation for bulk storage pools.

With CMR/PMR recording and 512e formatting, HUS724040ALE641 aligns with common enterprise file systems, backup targets, and object storage nodes, reducing risk in rebuild and scrub operations compared to host-managed alternatives. The 7,200 RPM class profile and on-drive cache are designed to sustain mixed read/write streams typical of backup repositories, log retention, and secondary datasets, while maintaining consistent behaviour across large RAID sets and JBOD shelves where airflow, bay density, and vibration can impact steady-state performance.

Why Choose the HUS724040ALE641?

HUS724040ALE641 delivers a pragmatic density-to-reliability balance for enterprise fleets that require scalable SATA capacity without sacrificing operational stability in multi-drive environments. By combining proven mechanics with enterprise error-handling expectations, HUS724040ALE641 supports predictable deployment in RAID arrays, backup tiers, and capacity nodes where uptime, service intervals, and consistent drive characteristics drive platform efficiency.

HGST Ultrastar engineering focuses on sustained datacentre duty cycles, disciplined qualification, and field-proven reliability targets aligned with modern server and storage standards. In environments sensitive to vibration and head positioning accuracy, the HUS724040ALE641 benefits from Dual Stage Actuator control and Rotational Vibration Safeguard to maintain dependable operation as bay counts scale.

Key Applications:

• RAID capacity tiers in rack servers
• Backup and recovery repositories
• Archive and compliance retention storage
• General-purpose bulk storage pools
