Dell 400-AIYK 1.2TB SAS Drive

The Dell 400-AIYK is a 1.2TB internal hard drive built for servers and storage arrays that need 10000 RPM performance over a SAS 12Gb/s link. Its 2.5 inch form factor fits hot-swap bays in Dell PowerEdge and compatible enterprise chassis.

Installation and hot-swap notes

The drive ships as a bare unit without a tray so you must mount it in the correct carrier for your server model. Insertion is tool-less once the carrier is ready, but the SAS connector must seat fully or the controller will not detect the drive.

Practical limits of SAS 12Gb/s

The 12Gb/s interface caps sustained throughput well below the theoretical maximum because the 10000 RPM platters and 1.2TB capacity set the real-world transfer ceiling. Random I/O latency is bounded by mechanical seek time so workloads needing sub-millisecond response should consider solid-state alternatives.

Questions about this item

How do I confirm the 1.2TB SAS drive is running at 10000 RPM after installation?

Check the drive's reported rotational speed in your RAID controller BIOS or OS disk utility; it should show 10000 RPM and a 12Gb/s link rate for the 400-AIYK model.

The listing says bare drive packaging — does the 400-AIYK include a hot-swap tray or caddy, or must I supply my own?

The drive is sold as a bare unit without a tray; you will need a compatible 2.5-inch SAS hot-swap caddy for your server or enclosure.

My chassis only takes 2.5-inch SAS drives — is the 400-AIYK the correct 1.2TB 10K 12Gb/s version for that bay?

Yes, the 400-AIYK is a 2.5-inch form-factor SAS drive with 1.2TB capacity, 10000 RPM and 12Gb/s transfer rate, matching those bay requirements.
