SKU CH-25CV-Y0YQG

A 4 TB 3.5 inch internal hard drive with 7200 rpm spindle speed and 12Gb/s SAS interface

  • 4 TB capacity stores large datasets
  • 7200 rpm spindle speed delivers responsive data access
  • 12Gb/s SAS interface provides high-throughput connectivity
  • 5-inch form factor fits standard desktop drive bays
  • Near-line SAS design suits mixed read-write workloads

Dell 400-ATKM 4 TB nearline SAS drive

The Dell 400-ATKM is a 4 TB internal hard drive built for nearline workloads on a 12Gb/s SAS interface. It spins at 7200 rpm in a standard 3.5 inch form factor. This new drive targets administrators adding capacity to compatible storage arrays or servers.

Fits SAS bays with 12Gb/s controllers.

This drive suits administrators expanding a SAS-based storage array or a server that already provides 12Gb/s SAS connectivity. Builders whose chassis or controller only accepts a different physical or electrical interface cannot use this unit.

12Gb/s SAS interface decides compatibility

The single specification that decides fit is the 12Gb/s SAS interface. A matching SAS backplane, HBA or RAID card is mandatory for the drive to function. Without that specific connection the 4 TB capacity and 7200 rpm spindle remain inaccessible.

Questions about this item

What is the sustained transfer limit of the 12Gb/s SAS interface?

The drive uses a 12Gb/s SAS interface; sustained throughput is limited by the 7200 rpm spindle speed and the SAS link rate.

How much heat and noise does the 3.5" 7200 rpm drive produce under continuous operation?

A 3.5" 7200 rpm near-line SAS drive generates typical enterprise-level heat and audible seek noise during all-day workloads.

Which host connector must my system provide for this 12Gb/s SAS drive?

The drive requires a 12Gb/s SAS host bus adapter, RAID controller or backplane with a compatible SAS connector.
