Dell Constellation ES 1TB SAS Hard Drive

The Dell Constellation ES ST31000424SS is a 1000GB internal hard drive built for 3.5-inch bays. It spins at 7200RPM and connects through a SAS 6Gb/s interface with a 16MB buffer. The unit ships new and includes an R Series caddy for direct installation into compatible Dell chassis.

Suited for servers and arrays needing SAS

This drive fits systems that accept 3.5-inch SAS drives with a 6Gb/s interface. It is not suitable for platforms that require a different physical interface or a 2.5-inch form factor. Buyers needing higher capacity or larger cache should consider other models.

SAS 6Gb/s interface determines compatibility

The single specification that decides fitment is the SAS 6Gb/s interface on a 3.5-inch frame. Verify that your backplane or controller supports this exact interface before purchase.

Questions about this item

How can I confirm the ST31000424SS is running at 7200 RPM after installation?

Use a SMART monitoring tool such as CrystalDiskInfo or the controller BIOS to verify the reported rotational speed matches 7200 RPM and that the SAS link negotiates at 6 Gb/s.

What is included with the drive and what must I source separately?

The package includes the 1 TB SAS drive and an R Series caddy/tray; you will need a compatible SAS backplane or HBA, SAS data and power cables, and a 3.5" drive bay if your chassis does not already provide one.

Which capacity version of the Constellation ES should I choose for a 1 TB requirement?

Select the ST31000424SS model — it delivers exactly 1000 GB with a 16 MB cache and 7200 RPM spindle speed, matching the stated capacity need.
