Dell 400-ALRY 4TB SAS Drive

This Dell 400-ALRY is a 4TB 3.5-inch internal hard drive built for nearline workloads. It spins at 7200 RPM and connects through a SAS 12Gb/s interface. The unit is supplied new and supports hot-swap installation.

Suits arrays needing high-capacity nearline storage

The drive fits servers and storage arrays that take 3.5-inch SAS drives and benefit from 4TB of nearline capacity. It is not for systems limited to 2.5-inch bays or interfaces other than SAS.

SAS 12Gb/s interface confirms host compatibility

The single specification that decides fit is the SAS 12Gb/s interface; the host backplane or controller must support this exact protocol. Verify the connection type before purchase.

Questions about this item

What drive bay size and tray type does the 400-ALRY require?

The 400-ALRY fits a standard 3.5-inch bay and uses a hot-swap tray, so it slides directly into a compatible caddy without tools.

How do you install the 400-ALRY in a Dell server and what step is often missed?

Insert the drive into the hot-swap bay until the carrier clicks; the step often missed is verifying the SAS 12Gb/s backplane negotiates the full 12 Gb/s link speed.

When will the 400-ALRY need replacement in a 7200 RPM nearline workload?

Plan replacement when SMART attributes show rising reallocated-sector counts or after the rated annualised workload limit for nearline SAS drives is reached.
