Dell 8TB 3.5" SATA Hard Drive

The Dell 400-AKWX is an 8TB internal hard drive built for desktop workstations and servers. It uses a 3.5-inch form factor and connects through a SATA 6.0Gb/s interface. A 128MB buffer supports sustained read and write operations at 7200 RPM. The drive ships as a bare unit without cables or mounting brackets.

Suited for bulk storage in compatible Dell systems

This drive fits users who need high-capacity mechanical storage for backups, media libraries or archival workloads in supported Dell desktops or servers. It is not intended for boot drives where low latency matters, nor for laptops or small-form-factor chassis that only accept 2.5-inch devices. Buyers requiring faster random access or a different physical size should consider other storage types.

SATA 6.0Gb/s interface determines compatibility

The single specification that decides fitment is the SATA 6.0Gb/s interface paired with the 3.5-inch form factor. The system must provide a standard SATA data and power connection plus a 3.5-inch drive bay. Buffer size and spindle speed are fixed at 128MB and 7200 RPM, so performance characteristics cannot be changed after purchase.

Questions about this item

What practical throughput does the SATA 6.0Gb/s interface cap at for the Dell 400-AKWX 8TB drive?

The SATA 6.0Gb/s interface limits real-world sequential transfer to about 600 MB/s, so the 7200 RPM drive will hit that ceiling before the interface does.

What physical space and mounting does the 3.5" form factor require for this Dell 400-AKWX drive?

It needs a standard 3.5-inch internal bay with four side or bottom screw holes and room for the SATA data and power connectors on the rear edge.

How is the Dell 400-AKWX installed, and what step do people often miss?

Mount the bare drive in a 3.5-inch bay, attach SATA data and power cables, then initialise and format the 8 TB volume in the OS before use.
