Product Identity

This 1.2TB SAS 12Gb/s internal hard drive spins at 10000 RPM in a 2.5" form factor. It is built for enterprise storage workloads and compatible with Dell PowerEdge FC630 and M630 servers.

Setup Requirements

Verify that your server or controller supports SAS 12Gb/s and provides a 2.5" hot-swap bay. The drive ships as a bare unit without a tray or caddy, so ensure the correct carrier is available for your chassis.

Thermals and Power

Enterprise 10000 RPM drives generate more heat than lower-speed models and require adequate airflow within the server enclosure. Power draw will be higher than nearline alternatives, so confirm your system cooling and power budget can accommodate the additional load.

Questions about this item

Does the 400-AJQD ship with any cables, tray or mounting hardware included?

The drive is supplied as a bare 2.5" SAS unit with no cables, tray or screws; a compatible hot-swap caddy and SAS data and power cables must be sourced separately for installation in a Dell PowerEdge server.

How do I decide between the 1.2 TB capacity and other capacities that might be offered for this 10000 RPM SAS line?

Choose the 1.2 TB model when the workload fits within 1.20 TB of raw space and the 12 Gb/s SAS interface meets throughput needs; larger capacities in the same family would add space but keep identical spindle speed and interface.

What does the 12 Gb/s SAS figure mean for real-world throughput inside a PowerEdge FC630 or M630?

The 12 Gb/s SAS link supports up to 12 Gb/s per lane between the drive and the controller; actual sustained transfer rates depend on the 10000 RPM mechanics and the RAID controller configuration in the server.
