Dell 4TB Nearline SAS Drive

The Dell 400-ALPR is a 4TB 3.5" Nearline SAS hard drive spinning at 7200 RPM with a 12Gb/s transfer rate. It is built for Dell servers and storage arrays that require high-capacity, nearline-class storage in a standard 3.5-inch form factor. The drive ships as a bare unit without a tray.

Suited for Nearline SAS Bays

This drive fits administrators expanding Dell PowerEdge or PowerVault systems that accept 3.5" Nearline SAS drives at 12Gb/s. It is not for platforms limited to 3Gb/s SAS signalling or those requiring a 2.5" form factor. Buyers needing a hot-plug tray or caddy must source that separately.

12Gb/s SAS Interface Decides Compatibility

The single specification that determines fit is the 12Gb/s SAS interface; the host backplane and controller must support this signalling speed to achieve the rated transfer rate. A system wired for 3Gb/s SAS will not negotiate the full 12Gb/s link. Verify the controller and backplane specification before purchase.

Preguntas sobre este artículo

How often should the 4TB 7200 RPM SAS drive be checked or replaced in a server?

Enterprise nearline drives are rated for continuous operation; monitor SMART attributes and replace if reallocated sectors or seek errors appear.

What limits sustained write throughput on the 12Gb/s SAS interface?

The 7200 RPM rotational speed and mechanical latency set the practical ceiling well below the 12Gb/s link rate.

How much heat and noise does the 3.5" 4TB SAS drive produce under all-day load?

Expect typical nearline HDD warmth and audible seek clicks; ensure chassis airflow matches the drive's operating temperature range.
