Cisco 1.8TB 12G SAS 10K RPM SFF HDD | SED, 4K Format, Enterprise — UCS-HD18T10NK9=

Add secure, high-capacity storage to Cisco infrastructure with a 1.8TB 12G SAS hard drive designed for enterprise deployment. The 10K RPM spindle speed provides a strong balance of capacity and responsiveness for mixed workloads, while the 12G SAS interface supports established server and storage backplanes. This model includes 4K format support and self-encrypting drive capability, making it a practical fit for organizations that need to align storage architecture with security policy. In regulated environments, encryption at the drive layer helps protect data at rest without changing application behavior. The small form factor supports dense chassis designs and simplifies replacement in supported systems. Compared with lower-capacity or slower mechanical drives, this model gives infrastructure teams more room to consolidate workloads while preserving the operational characteristics expected from enterprise SAS storage. It is a strong choice when storage must serve both performance and compliance requirements without moving to flash for every tier.
