18TB CMR Enterprise Hard Drive

The Seagate Exos X20 ST18000NM003D is an 18TB 3.5-inch internal hard drive built for enterprise storage. It spins at 7200 RPM with a 256MB cache and uses the SATA 6.0Gb/s interface. CMR recording technology and a helium-sealed design support high-capacity workloads in standard drive bays.

Suited for NAS and Data-Center Arrays

This drive targets cloud storage, hyperscale deployments, and NAS systems such as Synology or QNAP. It handles big-data analytics, object storage, distributed file systems, and enterprise backup. Builders who need a smaller capacity or a different form factor should look elsewhere.

SATA 6.0Gb/s Interface Decides Compatibility

The single specification that determines fit is the SATA 6.0Gb/s interface. Your system or enclosure must provide a standard SATA data and power connection for this 3.5-inch drive to operate.

Bu ürünle ilgili sorular

Will the 3.5-inch form factor with 26.10mm height fit my standard desktop drive bay?

Yes, the drive measures 147.00mm long, 101.85mm wide and 26.10mm high, matching the standard 3.5-inch desktop bay dimensions.

What is the correct way to connect the SATA 6.0Gb/s interface, and what common mistake should I avoid?

Attach both the SATA data cable and the 15-pin SATA power connector; a frequent error is leaving the power cable unseated, which prevents the drive from spinning up.

The helium-sealed design and 2,500,000 MTBF rating suggest long life — what maintenance or replacement should I plan for?

No user-serviceable parts exist inside the sealed helium enclosure; monitor SMART attributes for reallocated sectors and replace the drive if the health indicators degrade.
