Dell 400-AJOS 300GB SAS Drive

The Dell 400-AJOS is a new 300GB 2.5-inch internal hard drive with a SAS 12Gb/s interface spinning at 10000 RPM. It arrives as a bare drive with hot-swap capability for direct installation into compatible drive bays.

Suited for 10K SAS environments

This drive fits servers and storage arrays that accept 2.5-inch SAS drives running at 12Gb/s and require 10000 RPM performance. It is not for systems lacking a SAS backplane or controller, nor for users who need larger capacities or solid-state latency.

12Gb/s SAS interface decides fit

The single specification that determines compatibility is the SAS 12Gb/s interface; the host must provide a matching SAS connection and support 2.5-inch hot-swap trays for this drive to function.

Questions about this item

Does my server need a 12 Gb/s SAS controller to use the 400-AJOS drive?

The drive uses a SAS 12Gb/s interface so the host controller must support that speed for full performance.

Can I keep my existing 6 Gb/s SAS backplane when adding this 10000 RPM 2.5" drive?

The 400-AJOS is backward compatible with 6 Gb/s SAS backplanes but will run at the lower link speed.

How can I confirm the 300 GB drive is operating at 12 Gb/s after installation?

Check the negotiated link rate in your RAID controller BIOS or OS utility; it should report 12 Gb/s for this model.
