Exos X16 12 TB SAS drive

The Seagate Exos X16 ST12000NM006J is a 12 TB 3.5-inch internal hard drive built for enterprise workloads. It uses a SAS 12Gb/s interface and spins at 7200 RPM with a 256 MB cache. CMR recording technology provides consistent performance for sustained writes. The drive is supplied in new condition.

Suited for high-capacity arrays

This drive fits servers and storage arrays that need 12 TB of bulk capacity on a SAS backbone. It also serves cloud, backup and big-data deployments where sustained transfer rates up to 270 MB/s are required. Buyers who need a different interface or a smaller form factor should look at other models. Systems without a SAS controller cannot use this drive.

SAS 12Gb/s interface decides fit

The single specification that determines compatibility is the SAS 12Gb/s interface. Your host bus adapter or backplane must support this exact interface for the drive to function. No other connector or protocol will work with this unit.

Questions about this item

How do I verify the Exos X16 ST12000NM006J is performing correctly after installation?

Check that the drive identifies as ST12000NM006J in the RAID controller BIOS, then run a sequential read test; sustained throughput should reach the specified 270 MB/s on the SAS 12Gb/s link.

What ships with the ST12000NM006J and what must I source separately?

The package contains the 3.5-inch 12 TB SAS drive only; you must supply a SAS 12Gb/s backplane or HBA, power and data cables, and mounting screws for your chassis.

Which capacity of the Exos X16 series should I choose for a new enterprise array?

This model provides 12 TB per drive; select it when your capacity planning calls for 12 TB modules in a 3.5-inch SAS 12Gb/s form factor.
