Enterprise 3TB SAS drive

The HGST Ultrastar 7K4000 HUS724030ALS640 is a 3TB 3.5" internal hard drive built for 24x7 enterprise workloads. It spins at 7200 RPM with a 64MB cache and connects through a SAS 6Gb/s interface. The drive carries a 2.0 million hour MTBF rating for high-reliability environments.

Fits standard 3.5" bays with SAS backplanes

This drive requires a SAS 6Gb/s host controller or backplane and a 3.5" drive bay with appropriate power and data cabling. The SAS interface provides dual-port capability for path redundancy in multi-drive enclosures. SATA 6Gb/s models exist in the same series for configurations that need interface flexibility.

Sustained throughput with vibration safeguards

Under continuous load the Dual Stage Actuator and Enhanced Rotational Vibration Safeguard maintain positioning accuracy in multi-drive chassis. The 512e Advanced Format preserves compatibility with legacy sector-size expectations while the 2.0 million hour MTBF reflects the design target for always-on operation.

Questions about this item

Will the 7200 RPM spindle hit a thermal limit during 24x7 operation?

The drive is rated for 24x7 accessibility and carries a 2.0 million hour MTBF, so sustained spindle speed is supported within its enterprise thermal envelope.

How much noise and heat does the SAS 6Gb/s interface add under constant load?

The SAS 6Gb/s interface itself adds negligible heat; the 7200 RPM mechanism and 64 MB cache dominate thermal output, which the chassis airflow is designed to handle.

Do I need a SAS HBA or RAID card with a 6Gb/s port to use this 3.5" drive?

Yes, a SAS 6Gb/s host bus adapter or RAID controller with a compatible cable and backplane is required for the drive to function.
