Dell 4TB SAS 12G LFF drive

This 3.5 inch internal hard drive provides 4000GB of storage on a SAS 12Gbps interface spinning at 7200RPM. It is built for Dell PowerEdge servers such as the R230, R330, R430, R530, R630, R730, R730xd, R930, T330, T430 and T630. The drive suits administrators who need high-capacity bulk storage in a compatible chassis. It is not for systems that lack a 12Gbps SAS backplane or 3.5 inch drive bays.

Sustained workload behaviour

The 7200RPM spindle speed delivers consistent sequential throughput for streaming reads and writes across the full 4000GB capacity. SAS 12Gbps signalling maintains bandwidth during long backup, archival or surveillance recording sessions without the throttling seen on slower interfaces. Firmware tuned for Dell controllers preserves command ordering under heavy queue depths. Workloads requiring low-latency random IOPS at high queue depth will not be satisfied by this nearline drive.

Thermals noise and power

The 3.5 inch form factor dissipates heat through the server chassis airflow path without a dedicated fan on the drive. Typical idle and seek acoustics remain within the range expected for enterprise 7200RPM SAS drives. Power draw scales with rotational speed and SAS link activity, staying within the limits of standard backplane power budgets. Environments with restricted airflow or passive cooling may require additional case ventilation not addressed by the drive itself.

Questions about this item

How much heat does the 4000GB 7200RPM SAS 12Gbps drive generate under continuous load?

The 3.5" 7200RPM SAS 12Gbps mechanism produces typical enterprise nearline heat output; ensure your chassis airflow matches Dell's thermal specs for the R230 through R930 and T330 through T630.

What controller does the 3.5" SAS 12Gbps drive require to operate?

A 12Gbps SAS HBA or RAID controller with a 3.5" drive bay and backplane that supports 12Gbps SAS signalling is required for the ST4000NM0025 mechanism.

Will the 12Gbps SAS drive negotiate down on a 6Gbps backplane in a PowerEdge R430?

Yes, the 12Gbps SAS interface auto-negotiates to 6Gbps on older backplanes, so the drive works in R430, R530, R630, R730, R730xd and T430 systems.
