Dell 400-AJUP 1.8TB SAS Drive

The Dell 400-AJUP is a 1.8TB 2.5-inch SAS hard drive spinning at 10000 RPM. It targets administrators expanding storage in compatible Dell PowerEdge or PowerVault servers. The 12Gb/s interface supports high-throughput workloads. Hot-swap capability allows replacement without system downtime.

Verify SAS Backplane and Tray Fit

Confirm the server backplane supports 12Gb/s SAS signalling before ordering. The drive ships as a bare unit with a tray; ensure the tray matches the specific server generation. Check that the RAID controller or HBA recognises 1.8TB capacity. Firmware compatibility should be validated on the Dell support site.

Integrates Into Hot-Swap Bays

This drive slots directly into 2.5-inch hot-swap bays, freeing 3.5-inch slots for other uses. The SAS interface connects to existing backplanes without extra cabling. Dual-port SAS architecture provides path redundancy for critical arrays. The 10K spindle speed balances latency and capacity for mixed read-write workloads.

Questions about this item

Does the drive arrive with a mounting tray or caddy, or do I need to source one separately?

The unit is supplied as a bare drive without a tray; a compatible 2.5" SAS tray must be purchased separately for installation in a PowerEdge or PowerVault bay.

The listing shows both 1.2TB and 1.8TB — which capacity will I actually receive?

The manufacturer part number 400-AJUP corresponds to the 1.8TB model, while the specifications table lists the 1.2TB variant 400-AHNS; verify the part number on your order to confirm the exact capacity.

How does the 12Gb/s SAS interface affect real-world throughput in a 10K RPM drive?

The 12Gb/s SAS link provides a maximum theoretical bandwidth of 12Gb/s, but sustained transfer rates are limited by the 10000 RPM mechanics and will be lower than the interface ceiling.
