Capacity and Interface

The Dell 400-AEQT is a 4 TB internal hard drive built for near-line storage workloads. It uses a 3.5-inch form factor and connects through a 12 Gb/s SAS interface. The spindle runs at 7200 rpm to deliver consistent throughput for bulk data.

Target workloads

This drive suits servers and storage arrays that require high-capacity, cost-effective SAS storage for archiving, backup or secondary data sets. It is not intended for boot volumes or transaction-heavy databases that demand low-latency random access. Builders without a SAS host bus adapter or backplane should look elsewhere.

Deciding specification

The single specification that decides fit is the 12 Gb/s Near Line SAS interface. The system must provide a compatible SAS controller or backplane running at that speed; a mismatched interface will prevent the drive from being recognised or from operating at its rated performance.
