HUS728T8TAL4204 WD Ultrastar DC HC320 8TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD featuring 4Kn CMR bulk storage with the HUS728T8TAL4204

The HUS728T8TAL4204 is an 8TB 3.5in internal enterprise HDD designed for capacity-focused server and data centre storage tiers where predictable sustained writes and consistent latency matter more than peak IOPS. Integrated into modern x86 server platforms and SAS backplanes, it supports dense drive counts behind SAS HBAs or RAID controllers, aligning with scale-out storage nodes, backup repositories, and virtualization clusters requiring stable throughput under 24x7 duty cycles.

By combining CMR recording with a 4Kn sector format, the HUS728T8TAL4204 is optimized for filesystems and object storage stacks that benefit from reduced write amplification and improved alignment efficiency. The 7200 RPM class design and 256MB cache balance sequential performance with deterministic behavior, while SAS provides enterprise-grade signaling, dual-port capable infrastructure compatibility, and robust error handling for multi-path architectures and serviceable disk shelves.

Why Choose the HUS728T8TAL4204?

The HUS728T8TAL4204 delivers a pragmatic density-to-reliability profile for capacity tiers where fleet consistency is essential. Its enterprise SAS positioning supports scalable deployment across shared backplanes, predictable maintenance windows, and controller-based data protection, while the 4Kn CMR design reduces operational risk for sustained ingest workloads typical of backup, archive, and logging pipelines.

WD engineers the Ultrastar line for continuous operation with a 2.0 million hour MTBF target and enterprise firmware behaviors tuned for array environments. The platform aligns with modern data centre standards through controlled acoustics and power characteristics, and includes Secure Erase (SE) support to streamline compliant drive retirement and redeployment processes.

Key Applications:

• Capacity-oriented server storage tiers
• Backup repositories and restore staging
• Archive and cold data pools
• Log retention and security telemetry storage
• Scale-out NAS and object storage nodes
