Seagate Exos X18 14 TB SAS Drive

The Seagate Exos X18 ST14000NM004J is a 14 TB enterprise hard drive with a 12 Gb/s SAS interface. It uses a helium sealed-drive design to reduce weight and power consumption per terabyte. Digital environmental sensors monitor internal conditions for consistent operation in dense rack deployments.

Suited for Hyperscale and Cloud Storage

This drive targets cloud data centres and massive scale-out architectures that require maximum capacity per rack unit. The SAS interface supports dual-port connectivity for high-availability configurations. Buyers needing a SATA interface or a smaller capacity for desktop or entry-level server use should consider other models.

12 Gb/s SAS Interface Decides Compatibility

The drive connects via a 12 Gb/s SAS link, so the host controller, backplane and cabling must support that protocol and speed. A SATA-only backplane cannot operate this drive, and the SAS connection does not negotiate down to SATA signalling. Verify the infrastructure provides SAS ports before purchasing.

Questions about this item

How can I verify the 14 TB Exos X18 is operating correctly after installation?

Check that the drive reports its full 14 TB capacity in the RAID controller BIOS and run the manufacturer diagnostic to confirm zero reallocated sectors and a healthy SMART status.

What comes with the ST14000NM004J and what must I source separately?

The drive ships as a bare 3.5-inch helium-sealed unit with a 12 Gb/s SAS interface; you will need to provide SAS cables, a compatible HBA or RAID card, mounting screws and a drive bay.

Should I choose the 14 TB SAS model or the 18 TB SATA version for my array?

Select the 14 TB SAS drive when your controller uses 12 Gb/s SAS and you need dual-port redundancy; choose the 18 TB SATA model only if your backplane and controller are SATA-only.
