Dell 4TB SAS 12Gb/s Hard Drive

This Dell 400-ALNY is a 4TB internal hard drive spinning at 7200 RPM with a SAS 12Gb/s interface in a 3.5 inch form factor. It is built for Dell PowerEdge servers including the R430, R530 and T430. The drive uses a 512n sector format and supports hot-plug installation for straightforward capacity expansion.

Suits Servers Needing Hot-Plug SAS Storage

This drive suits administrators adding nearline capacity to compatible Dell PowerEdge servers that accept 3.5 inch SAS hot-plug drives. It is not for systems limited to 2.5 inch drive bays, nor for platforms requiring a different interface protocol or sector size than 512n. Buyers without a SAS backplane or controller should look elsewhere.

SAS 12Gb/s Interface Decides Compatibility

The single specification that decides fit is the SAS 12Gb/s interface combined with 3.5 inch hot-plug mechanics. Your server backplane and RAID controller must support this exact interface standard and form factor. Verify the system service manual for the R430, R530 or T430 to confirm the drive is listed as a supported part before purchase.

Questions about this item

Will this 12Gb/s SAS drive work with the 6Gb/s SAS backplane in my older PowerEdge server?

The drive uses a 12Gb/s SAS interface and is hot-pluggable. It will negotiate down to the backplane speed, so it functions in a 6Gb/s SAS environment.

How can I verify the 7200 RPM spindle speed is active after installation?

Check the drive properties in the RAID controller BIOS or OS disk utility; the reported spindle speed should read 7200 RPM.

The listing says bare drive — does the package include a 3.5" hot-plug caddy or mounting screws for a PowerEdge R430?

It ships as a bare 3.5" drive only. The hot-plug caddy and any mounting hardware must be sourced separately for the R430, R530 or T430.
