Seagate Exos X16 12 TB enterprise drive

The Seagate Exos X16 ST12000NM001G is a 12 TB helium-sealed hard drive built for 24x7 enterprise storage. It spins at 7200 RPM with a 256 MB cache and a SATA 6.0 Gb/s interface. The drive is tuned for large data transfers and low latency in hyperscale environments.

Verify SATA host and 3.5 inch bay

Confirm your system provides a SATA 6.0 Gb/s port and a standard 3.5 inch drive bay with at least 26.11 mm height clearance. The drive ships in 512e format and supports 4Kn fast format; check that your controller and operating system handle the chosen logical sector size. Bare drive packaging means no cables or mounting screws are included.

Sustained 261 MB/s with helium cooling

Maximum sustained transfer rate reaches 261 MB/s during continuous workloads. Helium filling reduces internal turbulence, allowing cooler, quieter operation under constant load. Digital environmental sensors monitor drive conditions to maintain performance. The 2.5 million hour MTBF rating reflects design for round-the-clock duty cycles.

Questions about this item

Does the bare drive include cables, brackets or any mounting hardware?

The unit ships as a bare drive only; SATA data and power cables, mounting screws and any tray or bracket must be sourced separately.

Should I select the 512e or 4Kn sector format for my server or NAS?

The drive leaves the factory in 512e mode and supports fast reformatting to 4Kn; choose 512e for broad OS and controller compatibility, or 4Kn if your platform explicitly requires native 4Kn sectors.

What sustained transfer rate can I expect from the 7200 RPM SATA 6.0Gb/s interface in a live array?

The drive is rated for a maximum sustained transfer rate of 261 MB/s, which is the practical ceiling for sequential workloads on the SATA 6.0Gb/s link.
