Dell 401-AASR 1.8TB SAS Drive

The Dell 401-AASR is a 1.8TB internal hard drive built for desktop and server bays that accept a 2.5 inch SAS interface. It spins at 10000 RPM and carries the original manufacturer part number 401-AASR. The drive ships as a bare unit without a tray or caddy. It is suited for arrays that need high-speed rotational storage.

Who This Suits and Who It Does Not

This drive fits systems with a 12Gb/s SAS backplane that can address a 1.8TB capacity in a 2.5 inch form factor. It is not for buyers who need a larger capacity than 1.8TB or a 3.5 inch form factor. It is not for platforms that require a drive supplied with a mounting tray.

Deciding Specification

The interface is SAS with a 12Gb/s transfer rate and the spindle runs at 10000 RPM. These figures determine whether the drive matches the controller and performance tier required by the target array.

Questions about this item

Which SAS controller or HBA with a 12 Gb/s port do I need to connect the 401-AASR drive?

The drive uses a SAS interface rated for 12 Gb/s transfer, so a controller or backplane that supports SAS at that speed is required for full performance.

Will the 2.5 inch 10K RPM drive fit and spin up in a 3.5 inch bay using an adapter bracket?

A 2.5 to 3.5 inch adapter bracket lets the drive mount securely; the SAS power and data connectors are identical, so the drive will operate normally.

How can I verify the 1.8 TB capacity and 10000 RPM speed are recognised after installation?

Check the BIOS or RAID utility — it should list the model 401-AASR with 1.8 TB capacity and report the spindle speed as 10000 RPM.
