Dell 400-AFMO 1.2TB SAS Drive

The Dell 400-AFMO is a 1.2TB 2.5" internal hard drive with a SAS 6Gb/s interface spinning at 10000 RPM. It is built for servers and storage arrays that require hot-swap capability and enterprise-grade reliability.

Suits High-IO Workloads Not Archive Storage

This drive suits administrators who need low latency and consistent throughput for databases or virtualisation. It is not for users seeking maximum capacity per bay for cold data or backup archives where rotational speed is secondary.

10000 RPM Spindle Speed

The 10000 RPM spindle speed determines the drive's random access performance and sustained transfer rates. Verify that your controller and backplane support this rotational speed and the SAS 6Gb/s link before purchase.

Questions about this item

What controller or backplane do I need to connect the SAS 6Gb/s interface on this drive?

You need a SAS host-bus adapter, RAID card or server backplane that supports 6Gb/s SAS signalling and provides power to a 2.5" hot-swap bay.

Will the 1.2TB 10000 RPM drive share a SAS backplane with older 3Gb/s SAS disks?

Yes — the drive negotiates down to 3Gb/s on a legacy backplane, though sustained throughput will be limited to the slower link speed.

How can I verify the drive is running at 10000 RPM and 6Gb/s after installation?

Check the controller BIOS or management utility; it should report 10K RPM and a negotiated link rate of 6Gb/s for this device.
