Dell 400-AHKK 4 TB SAS drive

This Dell 400-AHKK is a 4 TB 3.5 inch nearline SAS hard drive spinning at 7200 RPM with a 6 Gb/s interface. It ships as a bare drive with a hot-swap tray included and is built for enterprise storage workloads. The unit is supplied new in original Dell packaging.

Suits servers needing high-capacity nearline storage

It fits 13G PowerEdge servers and other systems that accept 3.5 inch SAS drives with a tray. Buyers who need SSD latency or a different physical interface should consider other options. The drive is not intended for laptops or compact desktops that only support 2.5 inch bays.

SAS 6 Gb/s interface

The single specification that decides compatibility is the SAS 6 Gb/s interface. Your backplane or controller must support this exact protocol for the drive to function. Without a matching SAS connection the drive cannot be used.

Questions about this item

Does the Dell 400-AHKK come with cables or mounting hardware, or must those be purchased separately?

The drive ships as a bare unit with a hot-swap tray included; SAS data and power cables are not supplied and must be sourced separately.

Which capacity and interface version should I select for a 13G PowerEdge server that requires a 3.5" SAS drive?

Choose the 4TB model with SAS 6Gb/s interface and 7.2K RPM speed; it matches the 3.5" form factor and tray supplied for 13G PowerEdge bays.

What does the 7.2K RPM rating mean for everyday throughput in a server array?

At 7200 RPM the drive delivers nearline SAS performance suited to bulk storage and sequential workloads in a 13G PowerEdge environment.
