Whether you’re building a robust media library, archiving precious data, or safeguarding critical backups, this 4-bay expansion lets you expand capacity while keeping your current NAS configuration intact. The unit is designed to integrate smoothly with ASUSTOR control workflows, enabling you to manage volumes and pools from your NAS interface.
• seamless ASUSTOR integration and control: Engineered specifically for ASUSTOR NAS systems, the Xpanstor 4 is optimized for easy integration with ASUSTOR ADM. It slots into your existing NAS environment, allowing you to manage the expansion from the same control panel you already rely on. This minimizes setup time and simplifies ongoing storage management, backups, and data protection tasks across your ASUSTOR fleet.
• Versatile use cases for growing data needs: Use the Xpanstor 4 as a high-speed extension for media libraries, surveillance storage archives, or large-scale backups. Its high-speed USB-C interface ensures quick initial data seeding, while the expanded capacity gives you room to scale as your media collections and business data grow. The unit’s design supports a range of storage configurations within the ASUSTOR ecosystem, making it a practical upgrade path for households and small to mid-sized offices.
• Future-ready design with broad compatibility: The USB 3.2 Gen 2 Type-C interface positions the Xpanstor 4 for current and future hardware, delivering high-speed data transfers when connected to compatible devices.
