Dell 400-AHID 8TB 3.5" SATA Drive

The Dell 400-AHID is an 8TB 3.5-inch internal hard drive spinning at 7200 RPM over a SATA 6.0Gb/s interface. It is built for Dell PowerEdge servers such as the R430, R630, R730, R730XD, T430 and T630 where high-capacity bulk storage is required. The 128 MB buffer helps sustain throughput for sequential workloads.

Hot-swap tray and Dell firmware

The drive ships in a hot-swap carrier that matches the drive bays of the listed PowerEdge models, allowing removal and insertion without powering down the chassis. Dell-specific firmware is pre-loaded to ensure correct reporting to the iDRAC management controller and to the RAID controller’s drive health monitoring. Retail or OEM packaging may vary but the carrier and firmware remain the same.

Tool-less bay installation

Installation consists of sliding the carrier into an empty 3.5-inch hot-swap bay until the latch engages; no screws or cables are needed because power and data connect through the backplane. The most common issue is inserting the drive into a bay whose backplane or RAID controller does not support 8TB SATA drives, which prevents the system from recognising the volume. Verifying the server’s drive-count limit and controller firmware beforehand avoids this problem.

Questions about this item

Will the 128 MB buffer on the Dell 400-AHID need any firmware updates or replacement over time?

The 128 MB buffer is a fixed hardware component on the drive and does not require maintenance or replacement; firmware updates for Dell drives are typically handled through the server's lifecycle controller if the vendor releases them.

What is the first limit the 7200 RPM spindle speed hits during sustained write workloads?

Sustained write performance is ultimately capped by the 7200 RPM mechanical latency and the SATA 6.0 Gb/s interface throughput ceiling.

How much heat and power does the 8TB 3.5" SATA drive draw when running continuously in a PowerEdge server?

The drive is designed for hot-swap server bays where chassis airflow manages heat; power draw varies by workload but stays within standard 3.5" enterprise SATA limits.
