Purpose-built server storage

The Dell 400-AOJC is a 1.2TB 10K RPM SAS hard drive in a 2.5-inch form factor designed for compatible PowerEdge servers. It targets administrators who need high-speed rotational storage for transactional workloads or database tiers.

Integration requirements

The drive connects via a 12Gb/s SAS interface and fits 2.5-inch hot-plug bays in the listed PowerEdge models. It requires a SAS backplane and controller; it will not operate on SATA-only connections. The tray is included for direct installation.

Sustained workload behaviour

At 10,000 RPM the spindle delivers consistent throughput for random I/O patterns typical of OLTP and virtualisation hosts. The SAS dual-port architecture maintains path redundancy during heavy queue depths without the latency spikes seen in burst-oriented architectures.

Questions about this item

At what spindle speed does the 400-AOJC hit its sustained throughput ceiling?

The 10000 RPM spindle sets the mechanical limit for sustained data rates on this drive.

What noise and heat should I expect from the 400-AOJC in a server workload?

A 10000 RPM SAS drive produces noticeable whir and warm exhaust under continuous operation.

Which controller interface must my system provide for the 400-AOJC to function?

The drive requires a 12Gb/s SAS backplane or HBA; SATA-only ports will not work.
