Seagate EXOS X24 12TB SATA 3.5" ST12000NM002H

Enterprise capacity drive

The Seagate EXOS X24 is a 12TB 3.5" internal hard drive built for enterprise workloads. It uses a SATA 6Gb/s interface and carries a 550TB per year workload rating with a 2.5M-hour MTBF. The drive includes Seagate Secure and ISE for hardware-based encryption. It is designed for maximum rack-space efficiency in high-density storage deployments.

Upgrade from lower-capacity arrays

This model replaces multiple smaller drives by delivering 12TB in a single bay. The jump is worth it when a server or storage array needs higher density without adding shelves. Advanced write caching and sustained transfer rates up to 285MB/s help maintain throughput during heavy write workloads. PowerChoice and PowerBalance features let administrators tune power draw for active and idle periods.

Fits standard 3.5" SATA bays

The drive installs in any 3.5" drive bay with a SATA data and power connection. Its enterprise-grade reliability suits NAS, RAID and JBOD configurations that demand continuous operation. The high capacity frees physical slots for future expansion or reduces the total drive count needed for a given raw capacity target. No proprietary controller or carrier is required beyond standard SATA infrastructure.
