DELL 400-ANWK 2TB 2.5" SAS 7.2K 12Gb/s internal hard drive

2TB Nearline SAS Drive

The Dell 400-ANWK is a 2TB 2.5-inch internal hard drive built for Dell PowerEdge servers. It spins at 7200 RPM and uses a SAS interface rated at 12Gb/s. Hot-pluggable design allows replacement without shutting down the system. This drive suits administrators expanding storage arrays in compatible rack or tower servers.

Upgrading from smaller SAS drives

Replacing lower-capacity nearline SAS drives with this 2TB model increases raw storage in the same bay count. The jump is worth it when current volumes are full and the server chassis has no free 3.5-inch bays. It also helps when a failed drive must be matched to the existing 12Gb/s backplane speed. Buyers who need faster random access or solid-state endurance should look elsewhere.

Check server model and backplane

Verify the server is a listed PowerEdge model such as R230, R330, R430, R630, R730, R730XD, T330, T430 or T630. Confirm the backplane supports 2.5-inch SAS drives and 12Gb/s signalling. Ensure the RAID controller or HBA recognises nearline SAS drives at this capacity. Buyers without a compatible Dell server or SAS backplane cannot use this drive.
