The BUFFALO TeraStation 5420 is a high-performance, business-grade desktop NAS designed to meet the storage demands of small-to-mid-size teams, creative studios, and remote offices. With a generous total capacity of 64TB delivered in a ready-to-use 4-bay package (4x16TB drives included), this system lets you deploy robust shared storage, fast backups, and centralized file access across Windows, macOS, and Linux workstations. Built for reliability under heavy workloads, the TeraStation 5420 combines enterprise-grade security features with flexible, user-friendly management, making it a smart cornerstone for collaboration, media libraries, archives, and workspace virtualization needs. Whether you’re streaming large video assets for a production team, preserving critical business documents, or enabling centralized file services for multiple departments, the 5420 provides the performance headroom and security you require while remaining compact enough for a conventional desk or small office rack.

• Out-of-the-box capacity and readiness: 64TB of total storage across four 16TB drives are included, enabling immediate, expansive shared storage for teams and departments without the waiting game of sourcing drives separately. This turnkey package is ideal for onboarding, backups, media libraries, and collaborative projects from day one.
• 4-bay desktop NAS design for compact offices: The compact desktop form factor combines space efficiency with robust storage expansion. It is designed to sit neatly on a desk, in a data closet, or alongside a small office rack, delivering centralized access without dominating your workspace. The 5420’s layout emphasizes quiet operation and straightforward drive maintenance, helping you minimize disruptions while maximizing uptime.
• Secure, enterprise-grade data protection: Beyond simple storage, the TeraStation 5420 emphasizes data security with AES-256 hardware encryption, strong user authentication, and access controls. Create encrypted volumes, implement role-based permissions, and enforce secure sharing policies to protect sensitive information and meet compliance requirements in business environments.
• Flexible networking and cross-platform compatibility: Designed to serve mixed environments, the 5420 supports common file-sharing protocols (SMB/CIFS, NFS, FTP) and works seamlessly with Windows, macOS, and Linux clients. Dual-network or bandwidth-multiplexing options help sustain fast data transfers, backups, and media streaming across teams and remote sites.
• Comprehensive management and growth-oriented features: The TeraStation 5420 offers web-based management with status monitoring, alerts, and centralized control. It scales with your business needs through flexible RAID options, scheduled backups, cloud integration, and compatible disaster-recovery workflows, giving IT teams a practical path from deployment to ongoing optimization.
