Seagate Enterprise Capacity 12TB 3.5″” SAS 12Gb/s 7200RPM Helium Hot-Plug Hard Drive (ST12000NM0027)

Seagate Enterprise Capacity 12TB 3.5″” SAS 12Gb/s Helium Hard Drive

The Seagate Enterprise Capacity 3.5 HDD (Helium) delivers high-capacity, high-performance bulk storage for demanding enterprise storage systems and datacenters. With 12TB of capacity, a 7200 RPM spindle, and a 256MB cache buffer on a 12Gb/s SAS interface, it provides the dual-port enterprise connectivity and throughput required for storage arrays, SANs, and scale-out storage environments.

The helium-sealed design reduces internal air resistance, enabling higher platter density, lower power consumption, and reduced weight compared to conventional air-filled drives — delivering a lower total cost of ownership for high-density rack deployments. Hot-plug capable for live drive swaps without system downtime.
