Dell 400-AFZQ 4TB SAS drive
The Dell 400-AFZQ is a 4TB 3.5-inch internal hard drive built for Dell PowerEdge servers. It spins at 7200 RPM and connects through a SAS 12Gb/s interface. The unit ships as a bare drive with a tray for direct installation in compatible bays. Condition is new.
Suited for nearline storage arrays
This drive suits administrators expanding nearline storage in Dell PowerEdge systems that accept 3.5-inch SAS drives. Buyers who need solid-state latency, a different interface, or a 2.5-inch form factor should look elsewhere. It is not intended for external enclosures or desktop PCs lacking SAS controllers.
SAS 12Gb/s interface
The single specification that decides fit is the SAS 12Gb/s interface. Your server backplane and controller must support this exact connection to recognise and use the drive. Verify the part number 400-AFZQ against your system service manual before purchase.

Questions about this item
Will my SAS controller or backplane accept the 12 Gb/s interface of this 400-AFZQ drive?
The drive uses a 12 Gb/s SAS interface and will negotiate down to the speed your controller or backplane supports, so it works with 6 Gb/s or 3 Gb/s hosts without changes.
Can I keep using my existing 6 Gb/s SAS cables and backplane with this 400-AFZQ drive?
Yes, standard SAS cables and 6 Gb/s backplanes are fully compatible; the drive simply operates at the lower link speed while retaining its 4 TB capacity and 7200 RPM performance.
How can I verify the 400-AFZQ is running at 7200 RPM and the expected 12 Gb/s link after installation?
Check the negotiated link speed and rotational speed in your RAID controller BIOS, SAS topology utility, or OS tools such as smartctl; they will report 7200 RPM and the active SAS rate.
