4TB SAS drive for Dell servers

This 4TB internal hard drive uses a 3.5-inch SAS 6Gb/s interface and spins at 7200RPM with a 128MB cache. It is built for Dell PowerEdge servers ranging from the T100 through the T640 series. The drive ships new with an R-series caddy for direct installation.

Suits direct replacement in listed PowerEdge models

The part fits the specific Dell server models named in the compatibility list including T20, T100, T105, T110, T300, T310, T320, T330, T410, T420, T430, T440, T605, T610, T620, T630, T640 and T710. Builders using non-Dell chassis or controllers without SAS 6Gb/s support should look elsewhere.

SAS 6Gb/s interface determines controller match

The single specification that decides fit is the 6Gb/s SAS interface; the host system must provide a compatible SAS backplane or HBA. Capacity, rotational speed and cache are fixed at 4TB, 7200RPM and 128MB respectively.

  • 7200 RPM spindle delivers fast sequential throughput
  • 128 MB cache smooths burst workloads

Questions about this item

Should I pick the 4 TB model for a Dell T430 server?

The 4 TB capacity matches the ST4000NM0023 part number and fits the T430 drive bays listed in the compatibility table.

How does the 7200 RPM speed perform inside a Dell T620?

At 7200 RPM the drive delivers consistent throughput for database and virtualization workloads on a T620 backplane.

What does the SAS 6 Gb/s interface limit in a T420 chassis?

The SAS 6 Gb/s link caps maximum transfer rate at the controller level, so sustained reads and writes cannot exceed that bandwidth.
