4 TB SAS drive for Dell servers

This 4 TB SAS hard drive fits Dell PowerEdge servers from the R210 through R930 families and ships with a compatible caddy. It is intended for administrators who need additional bulk storage in supported 3.5-inch bays.

Capacity and headroom

The 4 TB capacity suits archival workloads, backup targets and secondary data volumes where sequential throughput matters more than random IOPS. The 7.2 K rotational speed limits sustained transfer rates, so databases or virtualisation workloads that demand low latency will saturate the drive quickly.

Thermals, noise and power

The 12 Gb SAS interface and 7.2 K spindle produce typical enterprise drive heat and acoustic output for a 3.5-inch form factor. In normal operation the unit runs within standard server thermal envelopes without requiring extra cooling beyond the chassis airflow.

Questions about this item

Will the 12G SAS interface work with the 6G backplane in my R710 server?

The drive negotiates down to 6G on the R710 backplane, so it installs and runs at the controller's maximum speed.

How can I confirm the 7.2K spindle speed is active after installation?

Check the drive's SMART data or iDRAC inventory — both report the rotational speed as 7.2K RPM.

Does the compatible Dell caddy ship with the 3.5" drive or must I order it separately?

The listing states the drive comes with a compatible Dell caddy, so no separate tray purchase is required.
