Dell 1.2TB SAS Hard Drive

The Dell 400-AOQT is a 1.2TB 3.5" internal hard drive spinning at 10000 RPM. It uses a SAS interface for connection to compatible servers or workstations. The drive is supplied new in retail or OEM packaging.

Who This Suits

This drive suits administrators expanding SAS-based storage arrays or replacing failed units in Dell systems. Buyers whose controllers only support other interfaces cannot use this drive. Systems requiring a different physical form factor should look elsewhere.

10000 RPM SAS Interface

The 10000 RPM spindle speed and SAS interface are the decisive specifications for compatibility. Verify that your backplane and controller support SAS at this speed before purchase. The 1.2TB capacity and 3.5" form factor must also match the bay and storage requirement.

Questions about this item

How do I install the 3.5" SAS drive in a Dell server tray?

Slide the 3.5" drive into the hot-swap carrier until the SAS connector seats firmly, then lock the latch; the step most people miss is fully engaging the latch before closing the chassis door.

What maintenance will the 10000 RPM SAS drive need over time?

No scheduled maintenance is required; if the 1.2TB drive later shows SMART errors or excessive noise, replace the unit.

What limit appears first when the 10000 RPM drive runs sustained writes?

The 10000 RPM spindle speed and SAS interface set the sustained throughput ceiling; thermal throttling may engage before the interface saturates.
