Dell 1.2TB SAS 10K hot-swap drive

This Dell 400-AJUO is a new 1.2TB internal hard drive with a 2.5 inch form factor. It uses a SAS 12Gb/s interface and spins at 10000 RPM. The unit is supplied as a bare drive with a hot-swap tray. It is built for Dell server and storage arrays that require this specific part number.

Fits 12Gb/s SAS hot-swap bays only

This drive suits administrators replacing a failed Dell 400-AJUO or expanding a compatible 12Gb/s SAS enclosure. Buyers whose backplane or controller lacks SAS 12Gb/s support should look elsewhere. Systems limited to slower SAS speeds or different tray formats cannot use this unit.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface. The host backplane and controller must support this exact signalling rate and connector type. Without 12Gb/s SAS capability the drive will not function.

Questions about this item

Does the 400-AJUO ship with a caddy or screws, or do I need to source a 2.5" SAS tray separately?

The drive is supplied as a bare unit with hot-swap capability; a compatible 2.5" SAS tray or caddy must be purchased separately if your chassis does not already include one.

I see only one capacity listed — is the 1.2 TB version the right choice for a high-IOPS database volume?

At 10 000 RPM with a 12 Gb/s SAS link, the 1.2 TB model delivers the spindle speed and bus bandwidth suited to random-read-heavy database workloads.

What does the 12 Gb/s SAS rating actually deliver inside a PowerEdge server backplane?

The 12 Gb/s interface supports full duplex transfers up to 12 Gb/s per port, so sustained throughput is limited by the 10 000 RPM mechanics rather than the bus.
