Dell 1.2TB 2.5" SAS 10K Drive

This new Dell 400-AUXJ is a 1.2TB 2.5-inch internal hard drive with a SAS 12Gb/s interface spinning at 10000 RPM. It is built for servers and storage arrays that require high-speed enterprise storage in a compact form factor. The hot-swap tray allows drive replacement without powering down the system.

Suits SAS bays needing 10K speed

This drive fits 2.5-inch SAS drive bays that run at 12Gb/s and benefit from 10000 RPM performance. It is not for systems limited to slower transfer rates or lower spindle speeds. Buyers who need larger capacities or a different physical size should look at other models.

SAS 12Gb/s interface decides fit

The single specification that determines compatibility is the SAS 12Gb/s interface. The host controller and backplane must support this exact standard for the drive to function. Verify the system accepts SAS drives before purchase.

Questions about this item

Does my server need a SAS 12Gb/s backplane or controller for the 400-AUXJ to function?

Yes, the drive uses a SAS 12Gb/s interface and requires a compatible controller or backplane that supports 12Gb/s signalling to operate.

Will the 10000 RPM 400-AUXJ share a SAS 6Gb/s backplane with older 6Gb/s drives without slowing them down?

The drive is backward compatible and will negotiate down to 6Gb/s on an older backplane; existing 6Gb/s drives continue at their native speed while this unit runs at the lower link rate.

How can I verify the 400-AUXJ is running at 12Gb/s after installation?

Check the negotiated link speed in your RAID controller BIOS or OS utility — it should report 12Gb/s for this drive when connected to a 12Gb/s backplane.
