Dell 12TB SAS 12Gb/s Enterprise HDD

This Dell 400-AUTD hard drive delivers 12TB of near-line SAS storage in a 3.5-inch form factor. It spins at 7200 RPM with a 256MB buffer and uses a 12Gb/s SAS interface for high-throughput enterprise workloads. The drive ships factory-sealed in a hot-plug carrier designed for Dell PowerEdge 10th to 13th generation servers. It is built for 24x7 duty cycles in compatible rack and tower systems.

Suited for Dell PowerEdge server upgrades

IT teams expanding capacity in supported PowerEdge R-Series and T-Series servers will find this drive matches the required form factor and hot-plug tray. Systems that lack SAS 12Gb/s backplanes or cannot accept a 3.5-inch carrier will not be able to use this unit. Buyers needing a different interface protocol or a 2.5-inch form factor should look at alternative drives.

12Gb/s SAS interface and 3.5" hot-plug tray

The single specification that decides fit is the combination of a 12Gb/s SAS interface and the included 3.5-inch hot-plug carrier for 10th to 13th generation PowerEdge servers. The drive uses 512e formatting and presents a 12TB capacity at 7200 RPM. Verify that the target server lists the 400-AUTD part number in its qualified hardware list before purchase.

Questions about this item

What real-world throughput does the 12Gb/s SAS interface deliver on this 12TB drive?

The Near Line SAS 12Gb/s link caps at 12Gb/s; the 7200 RPM spindle and 256MB buffer determine sustained transfer rates in practice.

Which drive bays accept the 3.5" hot-plug tray supplied with this 400-AUTD unit?

The factory-sealed tray fits 10th to 13th generation Dell PowerEdge servers including R730, T630, R430, R530, T430 and R730xd.

How is the hot-plug carrier installed and what step is often missed?

Slide the carrier into the bay until the latch engages; the step people miss is pressing the release button fully so the lever locks the drive electrically.
