Dell 4TB 3.5" SAS Hard Drive

This Dell 400-ATKM is a 4TB internal hard drive built for desktop and server bays. It uses a SAS 12Gb/s interface and spins at 7200 RPM in a standard 3.5-inch form factor. The drive is supplied new in either retail or OEM packaging.

Suited for SAS bays needing 4TB at 7200 RPM

This drive fits systems that accept 3.5-inch SAS devices and require 12Gb/s throughput with 512n sector formatting. It is not for builds that lack a SAS host adapter or backplane, nor for users who need a different capacity or a 2.5-inch form factor.

SAS 12Gb/s interface decides compatibility

The single specification that determines whether this is the correct part is the SAS 12Gb/s interface; the host must provide a matching SAS connection for the drive to function.

Questions sur cet article

Does the Dell 400-ATKM 4TB SAS drive ship with a tray or caddy, or must I buy one separately?

The drive is sold as a kit that includes the carrier tray shown in the part number X7K8W, so no separate bracket is required for a compatible Dell bay.

The title lists both 7.2K RPM and 7200 RPM — which speed should I use when planning RAID rebuild times?

Both figures describe the same spindle speed of 7200 RPM; use that value for any RAID rebuild or throughput calculation.

What does the 12Gb/s SAS interface actually deliver in a server backplane that only supports 6Gb/s?

The drive will negotiate down to 6Gb/s on that backplane, limiting peak transfer to the slower link while retaining full 4TB capacity and 512n sector format.
