Seagate Exos X12 12TB SATA Drive

The Seagate Exos X12 is a 12TB 3.5 inch internal hard drive built for enterprise storage systems. It operates at 7200 RPM with a 256MB cache and a SATA 6.0Gb/s interface. The helium-sealed design supports 24x7 operation in servers, JBODs and business NAS environments.

Enterprise Workloads and Compatibility

This drive suits organisations that need high-capacity bulk storage with a 550TB per year workload rating and 2.5 million hour MTBF. It is not intended for desktop PCs or consumer NAS units that cannot sustain enterprise-class duty cycles. Systems requiring a different physical interface or form factor cannot use this SATA 3.5 inch device.

261 MB/s Sustained Transfer Rate

Advanced Write Caching helps deliver up to 261 MB/s data transfer rates for heavy application usage. This throughput figure is the key metric for deciding if the drive matches your storage array performance requirements.

Questions about this item

How much heat and power should I expect from the 7200 RPM helium drive when it runs 24×7?

The 3.5-inch helium design and PowerChoice feature keep power draw low and heat manageable during continuous operation, while the 2.5 million hour MTBF rating reflects reliability under sustained load.

My server backplane only has SATA 6.0Gb/s ports — will the Exos X12 connect without an adapter?

Yes, the drive uses a native SATA 6.0Gb/s interface and standard 3.5-inch form factor, so it plugs directly into any SATA backplane or controller without extra hardware.

Will the 256 MB cache and 261 MB/s transfer rate work well with my older 6 Gb/s RAID card?

The 256 MB cache and up to 261 MB/s sustained transfer rate operate fully within the SATA 6.0Gb/s bandwidth, so performance scales to the limit of your existing controller.
