Dell 1.2TB SAS 10K hybrid drive

The Dell 400-AOQT is a 1.2TB hybrid drive with a 10000 RPM spindle and a SAS 12Gb/s interface. It fits 2.5-inch bays and includes a carrier for hot-swap trays. The unit is designed for Dell PowerEdge and PowerVault systems that accept SAS storage devices.

Hot-swap carrier simplifies bay insertion

The supplied carrier lets the drive slide into compatible hot-swap bays without tools or cables. Alignment pins on the carrier must match the chassis slots; forcing the drive can damage the backplane connector. Firmware mismatches between the drive and the RAID controller are the most common cause of detection failures.

SAS 12Gb/s link caps sustained throughput

The 12Gb/s SAS interface limits maximum sustained transfer rates to the link speed. Mechanical latency at 10000 RPM restricts random I/O performance compared with solid-state media. The drive cannot exceed the bandwidth of the controller or backplane it is attached to.

Questions about this item

How can I verify the drive is running at 10000 RPM after installation?

Check the SMART data or system BIOS for a spindle speed of 10000 RPM and confirm the SAS link negotiates at 12Gb/s.

The packaging is listed as bare drive; does the tray carrier ship with it or must I order it separately?

The specifications show a drive carrier is included, so the tray ships with the bare drive.

Which capacity should I choose if my PowerEdge R720 array needs 1.2TB per bay?

Select the 1.2TB model; it matches the 1.2TB per bay requirement for the R720.
