Dell 3TB SAS Enterprise Drive

The Dell 4CMD9 is a 3.5 inch internal hard drive with a 3TB capacity and a SAS 6Gb/s interface. It spins at 7200 RPM and is supplied new in original Dell packaging. The drive includes a hot-swap tray for tool-less installation in compatible bays.

Suits servers and arrays needing SAS hot-swap

This drive fits Dell PowerEdge servers and storage arrays that accept 3.5 inch SAS drives with hot-swap trays. It is not for laptops, small-form-factor desktops or any system limited to 2.5 inch bays. Builders without a SAS backplane or HBA should look elsewhere.

SAS 6Gb/s interface determines compatibility

The single specification that decides fit is the SAS 6Gb/s interface. The system must provide a SAS port and a 3.5 inch hot-swap bay with the correct tray alignment. Without a SAS controller and matching bay, the drive will not function.

Questions about this item

Does this 3.5" SAS drive need a specific controller to function?

It requires a SAS 6Gb/s host-bus adapter or a backplane with native SAS ports to operate.

Will the 7.2K RPM spindle speed work in an array with slower nearline drives?

The 7200 RPM spindle matches standard nearline speeds, so it integrates without performance mismatch.

How can I confirm the 3TB capacity is recognised after installation?

The drive should appear as a 3TB SAS device in the RAID BIOS or operating-system disk utility.
