Capacity and interface
The Dell 400-AUWK is a 12TB 3.5-inch internal hard drive with a SATA 6.0Gb/s interface and 7200 RPM spindle speed. It uses a 512e disk format and includes a 256 MB buffer. The drive is designed for nearline storage workloads in compatible Dell systems.
Build integration
This bare drive requires a standard 3.5-inch bay and a SATA data plus power connection. It supports hot-plug and hot-swap operation in supported Dell PowerEdge servers, allowing insertion or removal without powering down the chassis. No mounting tray is included in the package.
Upgrade context
The drive replaces lower-capacity 3.5-inch SATA hard drives in supported Dell PowerEdge models such as the R330, R430, R730, R730XD, R730xd XL and T430. The jump is worthwhile when additional nearline storage is needed for archival, backup or bulk data workloads within those validated server platforms.
