TeraStation™ WS5020 IoT- Rackmount

Versatile IoT Storage and Backup

The Buffalo TeraStation WS5020 IoT Rackmount is a 4-bay NAS powered by Windows Server IoT 2019 Standard Edition, offering 8TB to 40TB capacities (4x2TB to 4x10TB). With an Intel Atom C3338 dual-core 1.5GHz processor and 8GB DDR4 ECC RAM, it supports up to 60 simultaneous clients for 24/7 operation. Designed for IoT scenarios, it manages edge-device data for surveillance, monitoring, or file serving, with seamless integration into Windows environments and Microsoft services like Azure and OneDrive. Pre-configured RAID 5 ensures out-of-the-box data protection.

High-Speed Connectivity and Security

Featuring a native 10GbE port (IEEE802.3bz-compliant) for up to 1,250MB/s transfer speeds, the WS5020 eliminates network bottlenecks, even on CAT 5e cables. It includes three USB 3.0 ports for external backups and supports protocols like iSCSI, CIFS/SMB, AFP, FTP, SFTP, NFS, and SNMP. Security is enhanced with a closed system, SSL encryption, FIPS 140-2 validation, and Active Directory support without CALs. Data Deduplication, Shadow Copy, and Storage Replica ensure efficient, secure backups.

Enterprise-Grade Reliability

Built in Japan with NAS-grade HDDs tested for reliability, the WS5020 supports RAID 0, 1, 5, and JBOD for flexible redundancy. It includes NovaBACKUP software, Hyper-V for virtualization, and a 3-year warranty (extendable to 5 years). The 1U rackmount design (TAA-compliant) with a rail kit ensures easy deployment. Users praise its plug-and-play setup but note the OS is not upgradable from Windows Server 2016 in some units. 24/7 North America-based support and optional data recovery services enhance reliability.
