Enterprise capacity drive

The Seagate Exos X16 ST14000NM002G is a 14TB 3.5-inch internal hard drive built for enterprise storage arrays. It spins at 7200 RPM with a 256MB cache and connects through a SAS 12Gb/s interface. The helium-sealed design reduces weight and power draw per terabyte while supporting 512e and 4Kn sector formats. A 5-year limited warranty and 2.5M-hour MTBF rating back the drive for continuous operation in rack-mounted systems.

Suited for scale-out storage

This drive targets cloud data centres and massive scale-out deployments that need maximum capacity per rack slot. The 14TB capacity and SAS interface suit workloads demanding sustained throughput and dual-port redundancy. Buyers who need a SATA interface, a smaller form factor, or a drive rated for desktop workloads should look elsewhere. The 26.11mm height also requires a drive bay that accepts standard 3.5-inch enterprise dimensions.

Straightforward rack installation

Installation follows standard 3.5-inch enterprise drive procedures: mount in a hot-swap carrier or fixed bay, attach the SAS data and power connectors, and configure the HBA or RAID controller for 12Gb/s operation. The helium seal is permanent and must not be breached; handle the drive by the edges to protect the side-sealing weld. Firmware should be updated before deployment to ensure compatibility with the storage enclosure’s sensor monitoring.

Questions about this item

What type of SAS controller or backplane is required for the 12Gb/s interface?

A SAS controller or backplane that supports 12Gb/s speeds is needed to utilise the full interface bandwidth of the ST14000NM002G.

Can this 3.5" drive fit in a standard server chassis alongside older 3.5" SAS drives?

Yes, the drive uses the standard 3.5" form factor with maximum dimensions of 147.00mm length, 101.85mm width, and 26.11mm height, matching typical enterprise bays.

How can I verify the 256MB cache and 7200 RPM speed are active after installation?

Check the drive properties in your RAID controller BIOS or operating system utilities; they will report the 256MB cache size and 7200 RPM rotational speed.
