10 TB SAS 12Gb/s 7200 RPM drive

The Seagate Exos X18 ST10000NM013G is a 3.5 inch internal hard drive with a 10 TB capacity and a SAS 12Gb/s interface. It spins at 7200 RPM and uses conventional magnetic recording. The drive is designed for data analytics, dense architectures and hyperscale storage environments.

Enterprise arrays and surveillance systems

This drive suits storage arrays, video surveillance systems and workloads that require a 550 TB per year rating with a 2.5 million hour MTBF. It includes PowerChoice and PowerBalance for customizable power use. Systems that lack a SAS 12Gb/s controller or backplane cannot use this drive.

SAS 12Gb/s interface

The SAS 12Gb/s interface is the single specification that determines compatibility. The drive delivers up to 270 MB/s transfer rates and features AES-256 hardware encryption with Seagate Secure. Verify that your controller and enclosure support SAS 12Gb/s before purchase.

Questions about this item

Which capacity of the Exos X18 should I choose for a surveillance array?

The 10 TB model provides 550 TB per year workload rating and 2.5 million hour MTBF, matching the density and endurance specs quoted for this drive.

What does the 270 MB/s transfer rate mean once the drive is installed in a server?

It is the maximum sustained data transfer rate the drive can deliver to the SAS bus, so sequential reads and writes will top out near that figure under typical workloads.

What does the SAS 12Gb/s interface limit in practice?

The 12 Gbit/s SAS link supports up to 12 Gbit/s raw bandwidth, which exceeds the drive's own 270 MB/s sustained throughput, so the drive rather than the interface sets the speed ceiling.
