Dell 400-AMPN 8TB SAS enterprise drive

This 8TB 3.5" SAS hard drive operates at 7200 RPM with a 12Gb/s interface. It is a non hot-swap unit supplied as a bare drive for internal desktop or server installation. The Dell part number 400-AMPN identifies the exact component for procurement tracking.

Suits arrays needing high-capacity SAS spindles

Administrators expanding SAS-based RAID or JBOD volumes where drives remain fixed after installation will match this specification. Buyers whose chassis or backplane requires hot-swap trays cannot use this drive in those bays.

12Gb/s SAS interface and 7200 RPM spindle speed

The 12Gb/s SAS link and 7.2K rotation determine sustained throughput and latency for the target workload. Verify that the host controller and backplane support 12Gb/s SAS before purchase.

Questions about this item

What maximum throughput does the SAS 12Gb/s interface actually deliver with this 7200 RPM drive?

The 12Gb/s SAS link caps burst transfers at 12Gb/s, but sustained throughput is limited by the 7200 RPM mechanics, typically well below the interface ceiling.

Does the 3.5" non hot-swap form factor require a specific tray or caddy to mount in a Dell server bay?

Yes, the bare 3.5" drive must be secured in a compatible Dell 3.5" drive tray or caddy before it can be screwed into a server chassis bay.

How is the 400-AMPN installed in a non hot-swap bay, and which step is most often missed?

Power down the system, attach the drive to a Dell 3.5" tray, slide the assembly into the bay, connect both SAS data and power cables, then secure the tray screws — skipping the tray screws is the common error.
