Dell 400-AUUN 10TB SAS Hard Drive

This Dell 400-AUUN is a 10TB 3.5-inch internal hard drive built for desktop systems. It uses a SAS 12Gb/s interface and spins at 7200 RPM. The drive arrives as a bare unit without a mounting tray. It is suited for storage expansion in compatible workstations or servers.

Buyers who need a 12Gb/s SAS connection

This drive suits builders who need a 12Gb/s SAS connection and a 7200 RPM spindle speed. It is not for systems that only accept a different physical interface or a smaller form factor. Buyers who require a drive with an included mounting tray should look elsewhere.

SAS 12Gb/s interface

The single specification that decides compatibility is the SAS 12Gb/s interface. The host controller or backplane must support this exact interface for the drive to function. Verify that your system provides a SAS 12Gb/s connection before purchase.

Questions about this item

How do I install the 3.5" SAS drive and what step is often missed?

Mount the bare 3.5" drive in a compatible bay, connect the SAS 12Gb/s data and power cables, then ensure the backplane or controller is set to 12 Gb/s mode; many builders leave it at 6 Gb/s by default.

What maintenance or replacement will the 10TB Nearline SAS drive need later?

As a mechanical 7200 RPM HDD it has no user-serviceable parts; plan to replace the entire 400-AUUN unit once SMART attributes report reallocated sectors or after the rated workload limit is reached.

What limit appears first on the 400-AUUN under sustained 12Gb/s writes?

The 7.2K spindle caps sustained throughput well below the 12 Gb/s interface ceiling, so sequential write speed hits the mechanical ceiling before the SAS link saturates.
