DELL MG03ACA400 4TB 7200RPM SATA 3.5" internal hard drive

4 TB 7200 RPM SATA enterprise drive

This 4 TB 3.5 inch SATA hard drive spins at 7200 RPM and includes a 64 MB cache. It is built for desktop workstations and entry-level servers that need large-capacity bulk storage. The drive ships new with an R Series caddy for tool-less installation in compatible Dell bays.

Compatibility checklist

Verify that your system has a free 3.5 inch drive bay and a SATA 6 Gb/s port on the motherboard or controller. Confirm the power supply provides a SATA power connector for the drive. The included caddy fits Dell R Series chassis; other enclosures may require a different mounting tray.

Thermals noise and power

At 7200 RPM the drive generates moderate heat and audible seek noise typical of enterprise mechanical disks. Power draw rises during spin-up and heavy random access but remains within standard SATA limits. Ensure the case airflow passes over the drive to keep temperatures in the normal operating range.
