12 TB SATA enterprise drive

The Seagate Exos X14 ST12000NM0008 is a 12 TB internal hard drive built for continuous operation in servers and storage arrays. It uses a SATA 600 interface and a 3.5 inch form factor to fit standard drive bays. The helium-sealed design reduces weight to approximately 1.52 lb and lowers operating power consumption to 10 W.

Capacity headroom at 12 TB

With 12 TB of storage and a 256 MB cache, the drive handles large sequential workloads such as backup, archiving and media repositories. The 7200 rpm spindle speed supports sustained throughput for multi-drive RAID sets. The 512e sector format ensures compatibility with legacy operating systems and older storage controllers that do not support native 4Kn addressing.

Helium build and SATA connectivity

Helium filling cuts internal turbulence, allowing seven disks to spin in a standard 1 inch height while keeping vibration low in dense chassis. The SATA 600 connector provides a familiar cabling path for existing backplanes and host bus adapters. The drive weighs 1.52 lb and measures 4 inches wide by 5.8 inches deep, matching the standard 3.5 inch footprint for tool-less trays. It is not suited for portable use or laptops requiring 2.5 inch drives.

Questions about this item

Will the 3.5" 12 TB Exos X14 fit in the same drive bay and use the same SATA/600 cables as my older 3.5" SATA drives?

Yes, it uses the standard 3.5" form factor and SATA/600 interface, so it mounts in the same bays and connects with the same data and power cables as earlier 3.5" SATA drives.

How can I confirm the ST12000NM0008 is running at its rated 7200 rpm and 256 MB cache after installation?

Check the drive model and firmware in BIOS or a tool such as CrystalDiskInfo; both will report 7200 rpm rotation speed and 256 MB buffer for the Exos X14.

Does the retail box include mounting screws and a SATA data cable, or must I buy them separately?

Packing may vary between retail and OEM; the drive itself is the only guaranteed item, so plan to supply 3.5" mounting screws and a SATA data cable if your chassis or controller does not already include them.
