Enterprise capacity drive

The Western Digital Ultrastar DC HC310 HUS726T4TALE6L4 is a 4TB 3.5-inch internal hard drive built for continuous operation in servers and storage arrays. It runs at 7200 RPM over a SATA 6.0Gb/s interface with a 256MB cache and CMR recording technology. The 512e format ensures compatibility with legacy and modern operating systems alike.

Upgrade from consumer drives

This model replaces desktop-class drives when workloads exceed occasional backups or single-stream media. The jump is worth it when the system writes around the clock, when vibration from multiple spindles is present, or when data integrity features such as Secure Erase and non-volatile cache are required. It is not for buyers who need more capacity than 4TB or who require a second drive for RAID expansion.

Sustained workload behaviour

Under sustained load the dual-stage micro actuator maintains head positioning accuracy while the non-volatile cache protects in-flight data during unexpected power loss. The 7200 RPM spindle delivers consistent throughput for sequential workloads without the thermal throttling seen in burst-oriented designs. Enterprise firmware prioritises reliability over peak benchmark speeds.

I korthet

  • Enterprise-grade reliability with 7200 RPM performance
  • 4TB capacity for large-scale data storage
  • 256MB cache accelerates read and write operations
  • CMR recording technology ensures consistent data integrity
  • Non-volatile cache plus dual-stage micro actuator protect data during power loss

Frågor om den här produkten

Will the 3.5-inch form factor fit my standard desktop drive bay?

Yes, the 3.5-inch form factor matches the standard desktop drive bay dimensions used in most tower and small-form-factor cases.

Does the SATA 6.0Gb/s interface require any special driver or BIOS setting during installation?

No special driver is needed; the drive is recognised by any modern BIOS or OS that supports SATA 6.0Gb/s, but ensure the SATA controller is set to AHCI mode for full performance.

How often should I run a secure erase on this CMR drive to maintain performance?

Secure erase is a one-time sanitisation feature, not a routine maintenance task; regular SMART monitoring and firmware updates are the ongoing maintenance steps.
