Dell 400-ATKN 4 TB desktop hard drive

The Dell 400-ATKN is a 4 TB internal hard drive built for desktop computers. It uses a SATA interface and spins at 7200 RPM in a standard 3.5 inch form factor. The drive is supplied new and arrives in either retail or OEM packaging.

Suited for bulk storage on SATA platforms

This drive suits users who need large-capacity mechanical storage on a system with a free SATA port and a 3.5 inch bay. It is not for builds that only accept M.2 or PCIe storage, nor for laptops or small-form-factor cases that lack 3.5 inch mounting. Buyers who require solid-state speeds should consider a different technology.

The SATA interface determines compatibility

The single specification that decides fit is the SATA interface; the motherboard or controller must provide a matching SATA data and power connection. Without a SATA port the drive cannot be used, regardless of its 4 TB capacity or 7200 RPM spindle speed.

Questions about this item

Does the 400-ATKN 3.5" SATA drive ship with mounting screws or a SATA cable, or must I buy them separately?

The drive is supplied in retail or OEM packaging that may vary; mounting screws and a SATA data cable are not included and must be purchased separately if your chassis or motherboard does not already provide them.

I see only one capacity listed for the 400-ATKN — is the 4 TB version the only option available?

Yes, the 400-ATKN is offered solely as a 4 TB model; no other capacities are produced under this part number.

What does the 7200 RPM rating mean for everyday desktop use with this SATA drive?

The 7200 RPM spindle speed gives faster sequential read and write performance than slower desktop drives, reducing load times for large files and improving overall system responsiveness.
