4 TB Nearline SAS Drive

The Dell 04G9M is a 4 TB 3.5 inch nearline SAS hard drive spinning at 7200 RPM with a 6 Gb/s interface. It is built for desktop and server bays that accept 3.5 inch SAS drives and need high-capacity bulk storage. The drive arrives new in original or OEM packaging.

Suits SAS-only storage arrays

This drive fits systems equipped with a SAS controller or backplane that can address 6 Gb/s nearline drives. Buyers whose hardware lacks a SAS host bus adapter or whose drive bays are limited to 2.5 inch form factors cannot install this unit. It is also unsuitable for workloads that demand solid-state latency or higher spindle speeds.

6 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6 Gb/s SAS interface; the system must provide a matching SAS port and 3.5 inch bay. Without that interface the drive will not be recognised, regardless of its 4 TB capacity or 7200 RPM speed.

Questions about this item

How do I install the 04G9M in a 3.5" SAS bay and which step is often missed?

Slide the drive into the 3.5" bay, secure it with screws or the carrier latch, then connect both the SAS data cable and the power cable; the step most often missed is attaching the power connector.

What maintenance or replacement will the 4 TB Nearline SAS drive need later?

As a mechanical 7200 RPM hard drive, it has no user-serviceable parts; plan to replace the unit once SMART attributes show reallocated sectors or the drive exceeds its rated workload.

What limit appears first on the 04G9M during sustained 6 Gb/s SAS transfers?

The 7200 RPM platters cap sustained throughput well below the 6 Gb/s interface ceiling, so mechanical media speed becomes the bottleneck first.
