Dell 4TB 3.5" SATA Hard Drive

This Dell 400-AENN is a 3.5 inch internal hard drive with a 4TB capacity. It connects via a SATA 6.0Gb/s interface and spins at 7200 RPM. The drive is supplied as a bare unit without a tray or caddy. It is designed for desktop systems that accept standard 3.5 inch SATA storage.

Ideal for desktop storage upgrades

This drive suits users adding bulk storage to a desktop PC, workstation or server that has a free 3.5 inch bay and a SATA port. Builders who need a 2.5 inch form factor, a different interface, or a drive that includes a mounting tray should look at other options.

SATA 6.0Gb/s interface

The single specification that decides compatibility is the SATA 6.0Gb/s interface. The system must provide a matching SATA data port and power connector for the drive to function.

Questions about this item

Will the 3.5-inch 7200 RPM SATA drive fit and run correctly in my older desktop that only has 3 Gb/s SATA ports?

The drive uses a SATA 6.0Gb/s interface and will negotiate down to 3 Gb/s on older ports, so it will work at the slower speed.

How can I verify the 4TB Dell 400-AENN is operating at the expected 7.2K RPM after installation?

Run the manufacturer diagnostic or a SMART tool; it should report 7200 RPM and a SATA 6.0Gb/s link speed when the drive is healthy.

Does the bare-drive package include mounting screws or a 3.5-inch tray, or must I buy them separately?

The unit ships as a bare drive only; screws, brackets or a Dell-specific tray are not included and must be sourced separately.
