3TB Nearline SAS Drive

The Dell 400-AATJ is a 3.5 inch internal hard drive built for desktop and server storage arrays. It delivers 3TB of capacity on a Nearline SAS interface running at 7200 RPM. The drive ships as a bare unit without a mounting tray. This part suits administrators adding nearline capacity to compatible Dell systems.

Servers Needing 7.2K Nearline Storage

IT teams expanding storage pools in SAS backplanes will find the 6Gb/s transfer rate and 12Gb/s interface speed match nearline workloads. The 7.2K spindle speed supports sequential throughput for backup, archive and bulk data tiers. Buyers who need a mounting tray included or a different interface should look at other parts. The bare drive packaging assumes existing carrier hardware is available.

SAS 12Gb/s Interface at 7200 RPM

The single specification that decides fit is the Nearline SAS interface operating at 12Gb/s with a 7200 RPM spindle. Controllers and backplanes must support this SAS generation and physical 3.5 inch form factor. Verify the host system accepts 3TB nearline drives before purchase. No other single figure determines compatibility.

Questions sur cet article

Does the 400-AATJ 3.5" SAS drive ship with a mounting tray or cables, or must they be purchased separately?

The drive is supplied as a bare unit only. No mounting tray, screws or data cables are included; these must be sourced separately for installation.

The specifications list both 12Gb/s and 6Gb/s transfer rates — which figure should I rely on when choosing a controller?

The drive's SAS interface supports up to 12Gb/s, but the nearline rating is 6Gb/s. A 12Gb/s controller will negotiate down automatically, so either generation works.

With a 7200 RPM spindle speed, what sustained throughput can I expect once the drive is in a desktop array?

At 7200 RPM the drive delivers nearline-class sequential performance suitable for bulk storage and backup workloads in a desktop or entry server.
