Capacity and interface
The Seagate Exos X16 ST14000NM003G is a 14TB 3.5-inch internal hard drive with a SATA 6.0Gb/s interface. It spins at 7200 RPM and includes a 256MB cache for enterprise workloads. A helium-sealed design supports 24x7 operation in dense racks. The drive uses 512e/4Kn sector formats with Seagate Secure encryption.
Suited workloads and limits
This drive suits hyperscale storage, cloud archives and massive scale-out deployments that prioritise capacity per rack and low latency on large sequential transfers. The 2.5M-hour MTBF rating targets continuous duty cycles. Builders needing a smaller footprint or a different interface should consider other form factors. Systems limited to 12TB per bay will not accept this capacity.
Deciding specification
The 14TB capacity combined with the SATA 6.0Gb/s interface determines whether this drive fits the storage array and controller. The 3.5-inch form factor requires a standard drive bay with 26.11mm height clearance. The 512e/4Kn FastFormat must match the host controller's sector-size expectations.

Questions about this item
How can I verify the ST14000NM003G is operating correctly after installation?
The drive should be recognised by the BIOS or OS at its full 14TB capacity, spin at 7200 RPM with a 4.16ms average latency, and report a healthy SMART status with no reallocated sectors.
What ships with the ST14000NM003G and what must I source separately?
The bare drive arrives in retail or OEM packaging without cables, mounting screws or a SATA power adapter; you must supply a SATA 6.0Gb/s data cable and a compatible power connector.
Which capacity version of the Exos X16 series should I choose for maximum density?
The ST14000NM003G provides 14TB; the series peaks at 16TB for 33% more petabytes per rack compared to 12TB drives, so select 16TB if your chassis and budget allow.
