14TB Enterprise SAS Drive

The Seagate Exos X16 ST14000NM002G is a 14TB 3.5-inch internal hard drive built for enterprise storage workloads. It spins at 7200 RPM with a 256MB cache and connects via a SAS 12Gb/s interface. A helium-sealed design supports the high capacity in a standard form factor.

Upgrade From Lower-Capacity SAS Drives

This drive replaces smaller SAS enterprise drives when arrays need more raw capacity per bay without changing the controller or backplane. The jump is worth it when 7200 RPM throughput and 12Gb/s bandwidth match the workload and the 4.16ms average latency meets the service-level target. Buyers who need faster access times or a different interface cannot use this model.

Fits Standard 3.5-Inch Hot-Plug Bays

The unit measures 26.10mm high, 101.85mm wide and 147.00mm long, matching common enterprise drive trays. Hot-plug support allows insertion or removal without powering down the enclosure. PowerChoice and PowerBalance technologies let the system manage idle power and performance trade-offs. A SAS 12Gb/s backplane or HBA is required to operate the drive.

Questions about this item

What 3.5" drive bay dimensions does the 26.10mm high Exos X16 need?

The drive fits a standard 3.5" bay measuring 101.85mm wide by 147.00mm long with a maximum height of 26.10mm.

How is the SAS 12Gb/s drive installed and what step is often missed?

Connect the drive to a SAS 12Gb/s backplane or HBA, then enable hot-plug support in the controller BIOS so the drive is recognised on insertion.

When will the helium-sealed 14TB drive need replacement?

The helium-sealed design has no user-serviceable parts; replace the drive when SMART attributes indicate wear or the 2048-bit firmware verification fails.
