Seagate Exos X18 ST10000NM018G 10 TB Hard Drive

SKU CH-KMCW-VX2V1

Enterprise hard drive with 10 TB capacity, 256 MB cache, SATA 600 interface and helium-sealed design for 2.5 M-hr MTBF reliability

  • 10 TB capacity stores millions of files
  • 256 MB cache accelerates data access
  • SATA 600 interface optimises burst performance
  • Helium-sealed design reduces power per terabyte
  • 5 million-hour MTBF ensures enterprise reliability

High-capacity enterprise hard drive

The Seagate Exos X18 ST10000NM018G is a 10 TB internal hard drive built for hyperscale cloud and massive scale-out data centres. It uses a SATA 600 interface and conventional magnetic recording to deliver high rack-space efficiency. A 256 MB cache buffer supports rapid burst performance for large sequential workloads.

Suited for bulk storage arrays.

This drive fits builders filling rack bays with maximum terabytes per slot and operators who value the PowerBalance feature for Watts-per-TB optimisation. It does not suit teams that need a different interface or a smaller physical footprint for dense compute nodes.

10 TB capacity with helium-sealed design

The helium side-sealing weld gives the 10 TB model proven leak protection and lower weight for reduced total cost of ownership. Digital environmental sensors monitor internal conditions to maintain consistent operation across the 2.5 million-hour MTBF rating.

Questions about this item

What physical space is required to mount the 10 TB Exos X18?

The drive fits a standard 3.5-inch internal bay and uses the SATA interface for both data and power connections.

How is the drive installed and which step is often missed?

Secure the drive with four side or bottom screws, connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then initialise the disk in the operating system — the initialisation step is the one most people forget.

What maintenance or replacement will the helium-sealed 10 TB drive need later?

The helium-sealed design requires no internal maintenance; plan replacement after the 2.5 million-hour MTBF rating is reached or if SMART attributes report reallocated sectors.
