TeraStation WS5020 Windows Server IoT Network Attached Storage devices are purpose-built as efficient data storage and backup solutions for small businesses. These devices run on the Windows Server IoT 2019 operating system, which is a binary equivalent to Windows Server 2019, and integrate seamlessly into Windows-based environments as well as with various Microsoft services such as Azure and OneDrive. This Windows Server version is only available on NAS through the OEM.

The TeraStation NAS offers flexibility to be used as you see fit, such as acting as a multi-purpose file server, a central backup hub for all your files (including backing up to and from cloud services), being set up as a NVR server for security cameras, or serving as a subscription-free backup and disaster recovery (BDR) appliance.
