Dell 1.8 TB SAS Drive

The Dell 400-AJQN is a new 1.8 TB internal hard drive with a 2.5 inch form factor. It connects via a SAS 12 Gb/s interface and spins at 10,000 RPM for fast data access. The drive is hot-pluggable and ships as a bare unit without a caddy or bracket.

Suits high-performance arrays

This drive suits administrators expanding Dell PowerEdge servers or storage arrays that accept 2.5 inch SAS hot-plug drives. The 10K spindle speed supports demanding workloads such as databases or virtualisation. It is not for systems that only accept 3.5 inch bays or that lack a SAS backplane and controller.

12 Gb/s SAS interface

The single specification that decides fit is the 12 Gb/s SAS interface. Your server or enclosure must provide a compatible SAS backplane and controller running at this speed. If the system uses a different drive protocol or cannot negotiate 12 Gb/s, the drive will not function correctly.

Questions about this item

Will the 2.5" form factor fit my server's hot-swap bay?

The drive uses a standard 2.5" form factor designed for hot-swap bays that accept SAS drives; verify your chassis supports 2.5" SAS trays before ordering.

How do I install the drive and what step is often missed?

Slide the drive into the hot-swap tray until the connector seats firmly, then lock the lever; the step often missed is ensuring the tray latch clicks fully to complete the SAS 12Gb/s connection.

When will the 10,000 RPM drive need replacement?

Enterprise 10,000 RPM SAS drives typically run several years under normal workloads; monitor SMART attributes and replace when reallocated sectors or latency increases appear.
