Dell 400-AKIH 6TB SAS drive

This Dell 400-AKIH is a 6TB internal hard drive built for desktop and server storage. It spins at 7200 RPM and connects through a SAS 12Gb/s interface in a 3.5" form factor. The drive arrives as a bare unit without cables or brackets.

Check SAS controller and hot-swap bay

Verify that your system has a SAS controller or backplane supporting 12Gb/s speeds before ordering. The drive is hot-pluggable, so it requires a compatible hot-swap bay or cage for that feature. Ensure the chassis accepts 3.5" drives and supplies the correct power connector.

Suits capacity-focused arrays; not for boot speed

This drive suits builders expanding storage arrays, NAS units or servers where high capacity and SAS reliability matter. It is not intended for users who need the low latency of solid-state media for operating-system boots or heavy random workloads. Buyers wanting silent desktop operation should also consider alternatives.

Questions about this item

Does the 400-AKIH ship with a mounting bracket or cables, or is it a bare 3.5" SAS drive?

It is supplied as a bare 3.5" drive only; brackets, screws and SAS cables must be sourced separately.

The listing shows a single 6 TB 7200 RPM model — are there other capacity or speed variants under the same part number?

Part number 400-AKIH identifies only this 6 TB 7200 RPM configuration; different capacities carry different Dell part numbers.

What does the 12 Gb/s SAS interface deliver for a 7.2K spindle in a typical server backplane?

The 12 Gb/s SAS link provides full bus bandwidth for the 7200 RPM mechanism, supporting hot-swap operation in compatible Dell chassis.
