4 TB NL-SAS 12Gb/s 7200 RPM drive

This 4 TB Dell hard drive uses a Near Line SAS interface running at 12Gb/s and spins at 7200 RPM. The 3.5-inch form factor fits standard internal drive bays in servers and storage arrays. It is supplied new in retail or OEM packaging.

Suited to near-line storage and bulk data workloads

The drive serves capacity-focused roles such as archival, backup targets and secondary storage where sustained throughput matters more than peak IOPS. It is not for workloads that require solid-state latency or higher spindle speeds. Buyers needing a different interface or smaller form factor should consider other options.

SAS 12Gb/s interface

The single specification that decides fit is the 12Gb/s SAS connection; the host controller or backplane must support this standard for the drive to operate. Verify that your system provides a compatible SAS port before purchase.

Questions about this item

What practical throughput does the SAS 12Gb/s interface cap at?

The SAS 12Gb/s interface caps at 12 Gb/s raw bandwidth; real-world throughput depends on the controller and workload.

What physical space and mounting does the 3.5" form factor require?

The 3.5" drive fits a standard 3.5-inch internal bay and uses the usual four side-mount screw holes.

How is the 400-ATKM installed, and which step is often missed?

Mount the drive in a 3.5" bay, attach the SAS data and power cables, then configure the drive in the RAID or HBA BIOS before the OS sees it.
