TaiwanSynology is a Taiwanese company founded in 2000 that specializes in network attached storage, backup appliances and surveillance recorders. Its DiskStation Manager (DSM) operating system is the most established in the category, covering Btrfs snapshots, cloud sync, and a Surveillance Station package that turns a NAS into a local network video recorder for IP cameras. Models with Intel or AMD processors run Container Manager, which is the usual way people self-host Home Assistant and similar services at home.

It entered network attached storage in 2024 with the NASync series, which became the highest-funded NAS campaign on Kickstarter. Its UGOS Pro operating system uses Btrfs by default and offers Docker containers, virtual machines and local AI photo recognition on the Intel-based models, alongside HDMI output and SD card slots that most rival NAS omit.
