Enterprise storage drive

The Seagate Exos X16 is a 16TB 3.5-inch internal hard drive with a SAS 12Gb/s interface and a 7200 RPM spindle speed. It includes 256MB of cache and an average seek time of 4.1ms for high-capacity data storage.

Suits high-capacity servers and arrays

This drive fits servers and storage arrays that accept a 3.5-inch SAS 12Gb/s device and need 16TB of capacity. Builders whose chassis or controller only supports a different physical interface or a smaller form factor should look at other options.

SAS 12Gb/s interface requirement

The drive connects exclusively through a SAS 12Gb/s port, so the host system must provide a compatible SAS controller or backplane. Without that specific interface the drive cannot be used.

Questions about this item

Does the ST16000NM004G need a SAS 12Gb/s controller to operate?

Yes, the drive uses a SAS 12Gb/s interface and requires a compatible SAS controller or HBA for connection.

Will the 16TB Exos X16 work in a chassis with existing 7.2K RPM SAS drives?

Yes, it shares the 7.2K RPM spindle speed and SAS 12Gb/s interface, so it integrates with similar enterprise drives.

How can I confirm the 256MB cache is active after installation?

Check the drive identification in your RAID utility or OS device manager; it will report the 256MB cache size for the ST16000NM004G.
