Capacity and interface

The Seagate Exos X14 ST14000NM0018 is a 14TB 3.5-inch enterprise hard drive built for SATA 6.0Gb/s interfaces. It spins at 7200 RPM with a 256MB cache and uses a helium-sealed design to deliver sustained transfer rates up to 261 MB/s. The drive is rated for 2.5 million hours MTBF and carries a five-year limited warranty.

Who this suits and who should look elsewhere

This drive suits hyperscale storage arrays, big data workloads and rack-mounted servers that prioritise maximum capacity per slot and low power per terabyte. It is not for systems that cannot accept a 3.5-inch form factor or that require a non-SATA interface. Buyers needing higher random IOPS or a smaller physical footprint should consider alternative storage types.

Deciding specification

The 14TB capacity on a single SATA 6.0Gb/s drive is the specification that determines fit; it provides 40% more petabytes per rack compared to lower-capacity models while maintaining a 4.16ms average latency and 512e/4Kn sector support.

Points forts

  • 14 TB capacity fits 40 % more petabytes per rack
  • 7200 RPM and 256 MB cache deliver up to 261 MB/s sustained transfer
  • 5 million-hour MTBF supports continuous enterprise workloads
  • Helium-sealed design with digital sensors protects against leaks and pressure changes
  • PowerBalance feature optimises IOPS per watt for data-centre efficiency

Questions sur cet article

What SATA host controller or backplane do I need to run this ST14000NM0018 at its full 6.0 Gb/s interface speed?

A SATA 6.0 Gb/s controller or backplane with a standard 3.5" drive bay and SATA power connector will let the Exos X14 reach its rated 261 MB/s sustained transfer rate.

Will this 14 TB helium-sealed Exos X14 work in an older server that only supports 512-byte sector drives?

Yes, the drive uses 512e emulation so it appears as 512-byte sectors to the host while writing 4Kn physically, keeping compatibility with legacy controllers.

How can I verify the drive is healthy and performing at its specified 2.5 million-hour MTBF after installation?

Monitor SMART attributes for reallocated sectors and pending sectors; a sustained transfer rate near 261 MB/s and average latency around 4.16 ms confirm normal operation.
