Enterprise 12 TB SAS drive

The Seagate Exos X16 ST12000NM002G is a 12 TB helium-sealed hard drive built for enterprise storage arrays. It runs at 7200 RPM with a 256 MB cache and connects through a SAS 12Gb/s interface. The 3.5 inch form factor fits standard server bays and the bare-drive packaging is intended for volume deployment.

Suited for high-capacity servers.

This drive suits administrators who need dense, reliable capacity for cloud or scale-out data-centre workloads. The helium design and PowerBalance feature optimise watts per terabyte, while Seagate Secure aids drive retirement. Buyers who require the low latency or high IOPS of solid-state storage should look elsewhere, as should anyone whose platform lacks a SAS controller or backplane.

SAS 12Gb/s interface decides compatibility

The single specification that determines fit is the SAS 12Gb/s interface; the drive will only operate in systems equipped with a compatible SAS host bus adapter or RAID controller. SATA-only backplanes cannot use this model, so verifying the host connection is essential before purchase.

商品問答

Should I choose the 12TB or 16TB Exos X16 model?

The 12TB ST12000NM002G gives 12TB usable space; the 16TB version provides 33% more petabytes per rack but is a different part number.

What does the 7200 RPM speed mean for real workloads?

7200 RPM with 4.16ms average latency and 256MB cache delivers the highest 16TB-class performance for cloud and massive scale-out data centre applications.

How does the SAS 12Gb/s interface limit transfer rates in practice?

SAS 12Gb/s caps the drive at 12 gigabits per second, optimised for large data transfers and low latency in enterprise storage arrays.
