Dell 400-AAFV 4TB Nearline SAS Drive

This Dell 400-AAFV is a 4TB 3.5-inch nearline SAS hard drive spinning at 7200 RPM with a 12Gb/s interface. It arrives as a bare drive intended for enterprise storage arrays and compatible Dell servers.

Suits administrators expanding nearline SAS capacity

It fits IT teams adding bulk storage to systems that accept 3.5-inch SAS drives running at 7.2K speed. It does not suit builders whose chassis or controller only supports 2.5-inch form factors or a different drive interface.

12Gb/s SAS interface

The drive communicates over a 12Gb/s SAS link, so the host controller and backplane must support that signalling rate. Verify the system accepts 3.5-inch nearline SAS drives before purchase.

Questions about this item

Does my system need a 12 Gb/s SAS controller to use this 4TB drive?

The drive uses a SAS 12Gb/s interface, so a compatible SAS controller or backplane is required for operation.

Will this 7200 RPM Nearline SAS drive work in a server that currently runs 6 Gb/s SAS drives?

Yes, the 12 Gb/s SAS interface is backward compatible with 6 Gb/s SAS infrastructure, allowing mixed-speed deployments.

How can I verify the 4TB capacity and 7200 RPM speed are recognised after installation?

Check the drive properties in your RAID controller BIOS or operating system disk management; both should report 4TB capacity and 7200 RPM.
