Seagate Exos X14 ST12000NM0008 12 TB 3.5" SATA Hard Drive

Enterprise 12 TB Helium Drive

The Seagate Exos X14 ST12000NM0008 is a 12 TB 3.5-inch internal hard drive built for business-critical workloads, enterprise data archiving and surveillance storage. A helium-sealed design and a 2.5 million-hour MTBF rating target environments that demand sustained reliability.

SATA 6Gb/s Integration

The drive connects through a standard SATA 6Gb/s interface and requires both +12 V and +5 V power rails from the host system. At 7200 RPM with a 256 MB cache it delivers up to 261 MB/s sustained transfer, fitting into existing SATA backplanes without controller changes.

Capacity and Workload Limits

Twelve terabytes provide substantial space for sequential archives and write-heavy surveillance streams, while the 5.0 W idle and 10.0 W peak power envelope keeps thermal load predictable. Random 4K performance reaches 170 IOPS read and 418 IOPS write at queue depth 16, so heavy random databases or virtualised boot volumes will saturate the drive well before capacity runs out.
