Dell 4TB Nearline SAS Drive

The Dell 400-ALRX is a 4TB internal hard drive with a 3.5" form factor and a SAS 12Gb/s interface. It operates at 7200 RPM and is supplied as a bare drive with hot-swap capability for compatible bays. This new unit carries the original Dell part number 400-ALRX.

Suits servers needing high-capacity SAS storage

This drive fits systems that accept 3.5" SAS drives and require 4TB of nearline capacity at 7.2K speed. It is not for builds limited to 2.5" bays or interfaces other than SAS. Buyers needing a different capacity or form factor should consider other options.

Interface is SAS 12Gb/s

The drive connects via a SAS interface running at 12Gb/s transfer rate. The host system must provide a compatible SAS backplane or controller to use this drive. Without that specific interface support, the drive cannot function.

Questions about this item

How much heat and noise does the 400-ALRX produce when spinning at 7200 RPM all day?

The drive runs at 7200 RPM with a 12Gb/s SAS interface; typical nearline SAS drives at this speed draw moderate power and emit audible seek noise under sustained load.

What host connector and cabling must I already have for the 400-ALRX to work?

You need a SAS 12Gb/s backplane or controller with a compatible 3.5" hot-swap bay and SAS data and power cables.

Will the 400-ALRX work in a chassis that only supports 6Gb/s SAS backplanes?

The drive uses a 12Gb/s SAS interface and will negotiate down to the backplane speed, but maximum throughput will be limited to 6Gb/s.
