Capacity and interface

The Dell 400-ATKM is a 4 TB internal hard drive built for 3.5-inch bays. It uses a SAS 12Gb/s connection and spins at 7200 RPM. The drive targets servers and workstations that need nearline storage with a 512n advanced format.

Throughput and limits

Sustained external transfers reach 1.2 GBps over the SAS link. The 7200 RPM spindle gives low average latency for random reads and writes. Workloads that exceed the 4 TB capacity or demand higher IOPS will need additional drives or a faster media tier.

Packaging and integration

The unit ships as a bare drive without cables, brackets or software utilities. Retail or OEM packing may vary. Installation relies on the host chassis providing power and a compatible SAS backplane or controller.

Questions sur cet article

Will this 12 Gb/s SAS drive negotiate down to 6 Gb/s on my older controller?

Yes, the SAS 12 Gb/s interface auto-negotiates to 6 Gb/s or 3 Gb/s on legacy controllers without any jumper changes.

How can I confirm the 4 TB nearline drive is running at 7200 RPM after installation?

Check the spindle speed in SMART data or the BIOS hardware monitor; both will report 7200 rpm when the drive is spinning normally.

The listing says bare drive — does the 3.5" unit ship with mounting screws or a SAS cable?

No, bare-drive packaging includes only the drive itself; mounting screws and a SAS data cable must be sourced separately.
