Dell 4TB Nearline SAS Drive

This is a Dell 400-ADKK 4TB 3.5-inch internal hard drive using a 12Gb/s SAS interface and spinning at 7200 RPM. It arrives as a bare drive with hot-plug capability for supported bays. The nearline design targets bulk storage in enterprise servers and storage arrays.

Suited for capacity expansion

It fits administrators adding high-capacity nearline storage to compatible Dell PowerEdge or PowerVault systems that accept 3.5-inch SAS drives. Buyers needing faster random-access speeds or lower latency for transactional workloads should consider alternative drive types.

Interface speed is 12Gb/s SAS

The drive connects via a 12Gb/s SAS interface standard, which determines host-controller and backplane compatibility. Verify that your chassis and controller support this specific signalling rate before purchase.

Questions about this item

Will the 3.5" form factor fit a standard desktop drive bay?

Yes, the 3.5" form factor matches standard desktop internal drive bays and uses the common SAS connector layout.

How is the drive installed and what step is often missed?

Slide the bare drive into a 3.5" bay, connect the SAS data and power cables, then ensure the controller is set to 12Gb/s mode so the interface runs at full speed.

What maintenance or replacement should be planned for this 7200 RPM Nearline SAS drive?

Treat it as a mechanical drive: monitor SMART health, keep backups current, and replace the unit if reallocated sectors or seek errors appear.
