Dell 400-ALDL 8TB SAS Drive

This Dell 400-ALDL is an 8TB 3.5-inch internal hard drive built for nearline workloads. It spins at 7200 RPM and connects through a SAS 12Gb/s interface. The drive ships as a bare unit with a hot-swap tray design. It suits storage arrays and servers that require high-capacity bulk storage.

Who This Suits And Who It Does Not

The drive fits systems with SAS backplanes that accept 3.5-inch hot-swap trays. Buyers whose hardware lacks SAS connectivity or cannot accommodate a 3.5-inch form factor should look at other options.

Deciding Specification

The SAS 12Gb/s interface is the single specification that determines compatibility. Verify that your controller and backplane support this exact interface before purchase.

Questions about this item

Does the 400-ALDL require any scheduled maintenance or wear-related part replacement?

No, the 400-ALDL is a sealed mechanical drive with no user-serviceable parts; it runs until the SAS interface or the motor bearings reach end of life.

What limits sustained write throughput on the 8 TB 7200 RPM SAS drive?

The 12 Gb/s SAS link and the 7.2 K spindle speed cap sequential transfer rates before any thermal throttle activates.

How much heat and noise does the 400-ALDL produce during all-day operation?

As a 3.5 inch nearline SAS drive it generates typical enterprise HDD heat and audible seek noise, requiring standard server airflow.
