Enterprise SAS drive for 18TB capacity
The Seagate Exos X18 ST18000NM005J is an 18TB 3.5-inch hard drive built for enterprise storage arrays and hyperscale data centres. It runs at 7200 RPM with a 256MB cache and a SAS 12Gb/s interface. The helium-sealed design supports high areal density and a 2.5M-hour MTBF rating.
Installation requires SAS host bus adapter
This drive uses a SAS 12Gb/s interface and is not compatible with standard desktop PC motherboards that only provide SATA ports. A dedicated SAS HBA or RAID controller with appropriate cabling is required for connection. The 26.10mm z-height fits standard 3.5-inch drive bays, but the system must supply adequate cooling for 7200 RPM operation.
Verify controller and backplane support SAS
Before ordering, confirm that your storage chassis, backplane and host bus adapter all support 12Gb/s SAS signalling. The drive uses 512E/4Kn sector formats with Seagate Secure encryption, so the controller must handle those formats. Ensure the enclosure provides sufficient airflow for the helium-sealed mechanism and that your firmware recognises 18TB capacity.

Perguntas sobre este artigo
How can I verify the Exos X18 ST18000NM005J is operating correctly after installation?
Check that the SAS 12Gb/s link negotiates at full speed, confirm the 18TB capacity appears in the RAID controller BIOS, and monitor SMART attributes for reallocated sectors and the 2.5M-hour MTBF rating during initial burn-in.
What ships with the ST18000NM005J and what must I source separately?
The drive itself in retail or OEM packaging; you must supply a SAS 12Gb/s HBA or RAID card, compatible backplane cables, a 3.5" drive bay with 26.10mm clearance, and 12V/5V power from the server chassis.
Which Exos X18 variant should I choose for a high-density storage node?
Select the ST18000NM005J with 18TB capacity, 7200 RPM, 256MB cache, SAS 12Gb/s interface and 512E/4KN SED format to maximise petabytes per rack and enable Seagate Secure instant erase.
