Dell 8 TB Nearline SAS Drive

The Dell 400-AMJF is an 8 TB 3.5 inch nearline SAS hard drive spinning at 7200 RPM. It is built for servers and storage arrays that need high-capacity bulk storage with dual-port SAS connectivity. Buyers who need boot drives or low-latency transactional performance should look elsewhere.

SAS 12 Gb/s Interface Limits

The drive supports a 12 Gb/s SAS link but the specifications also list a 3 Gb/s average latency figure that reflects the mechanical rotational delay. Throughput will be bounded by the 7200 RPM spindle speed and the SAS protocol overhead. Systems limited to 3 Gb/s or 6 Gb/s backplanes will operate at the lower negotiated speed.

Installation Notes

The unit ships as a bare 3.5 inch drive without a mounting tray or caddy. Installers must supply a compatible hot-plug carrier or fixed bracket for the target chassis. Ensure the backplane provides both SAS data and power connections; a missing 12 V rail is a common cause of spin-up failure.

Questions about this item

Which SAS speed should I choose for this 8TB 3.5" drive?

The part is supplied with a 12Gb/s SAS interface; your controller will negotiate the highest link speed it supports.

What does the 7.2K speed mean once the drive is installed in a real machine?

7.2K equals 7200 RPM, giving typical nearline throughput and latency for bulk storage workloads.

What does the SAS interface cap in practice?

The SAS link runs at up to 12Gb/s, so sustained transfer is limited by the drive’s mechanical speed and the controller’s queue depth.
