Dell 084KR4 4TB SAS drive

The Dell 084KR4 is a 4TB 3.5-inch internal hard drive with a SAS 12Gb/s interface spinning at 7200 RPM. It is built for nearline storage workloads in compatible Dell servers and arrays. Supplied as a bare drive with a hot-swap tray, it arrives in new condition ready for installation.

Suited for capacity-focused nearline tiers

This drive suits administrators expanding nearline storage pools where sequential throughput and cost per terabyte matter more than low latency. Environments that require a different physical interface or solid-state speeds should evaluate alternatives.

SAS 12Gb/s interface requirement

The single specification that determines fit is the SAS 12Gb/s interface; the host backplane or controller must support this exact connection. Without a compatible SAS link the drive will not function.

Questions about this item

How do I install this 3.5" SAS drive in a hot-swap bay and what step is often missed?

Slide the drive into the bay until the connector seats firmly, then lock the carrier latch; the step often missed is securing the latch fully so the 12Gb/s link stays connected under vibration.

What maintenance or replacement will this 7200 RPM nearline drive need later?

Plan to replace the drive after its rated service life or if SMART attributes show reallocated sectors; no user-serviceable parts exist inside the sealed helium enclosure.

What limit appears first on this 4TB SAS drive during sustained 7.2K workloads?

The 12Gb/s interface bandwidth saturates before the mechanical throughput peaks, so sustained writes level off at the controller’s maximum sustained transfer rate.
