Dell 381CG 8 TB SAS hard drive

This Dell 381CG drive provides 8 TB of storage in a 3.5 inch form factor. It spins at 7200 RPM and connects through a SAS 12Gb/s interface. The unit is supplied as a bare drive without a tray. It is built for nearline workloads that demand sustained throughput.

Ideal for servers and storage arrays needing SAS

This drive suits administrators expanding Dell PowerEdge or compatible SAS backplanes where 12 Gb/s bandwidth is available. It is not for systems that lack a SAS controller or that accept only 2.5 inch bays. Desktop boards without enterprise drive support should look elsewhere.

SAS 12Gb/s interface determines compatibility

The single specification that decides fit is the SAS 12Gb/s interface; the host must provide a matching controller and backplane. Capacity of 8 TB and 7200 RPM speed follow once the interface requirement is met. Verify controller and firmware support before purchase.

Questions about this item

What controller or backplane do I need to run this 12 Gb/s SAS drive?

A SAS host-bus adapter, RAID controller or server backplane that supports 12 Gb/s SAS is required for the 381CG to operate.

Will this 7.2K Nearline SAS drive work in a system that currently uses 7.2K SAS drives?

Yes, the 381CG uses the same 12 Gb/s SAS interface and 7.2K spindle speed, so it will integrate with existing 7.2K SAS volumes.

How can I verify the 381CG is running at 12 Gb/s after installation?

Check the negotiated link speed in your RAID controller BIOS or OS utility; it should report 12 Gb/s for this drive.
