Customize storage to fit your needs
Synology NAS empowers you to securely store terabytes of data at your home, without any of the monthly fees that come with cloud storage. Our NAS and expansion units support a variety of hard disks (HDD) and flash drives (SSD), allowing you to adjust and expand your storage to fit your needs.


Access and share your files intuitively
Providing you with simple options to store, access, and share data is what a Synology NAS does best. Upload files at the speed of your local connection, share them quickly through secure sharing links, and access them from any browser, desktop, or mobile device.
Back up your PCs and Macs automatically
Keep files synced across all your devices with the Synology Drive private cloud. Drive also allows you to restore documents to a previous version when things go wrong. If you are using macOS, you can use Time Machine to back up files to your Synology NAS.


Safeguard and organize your media
Let Synology Photos automatically back up photos and videos taken on mobile devices. To save you time, the system groups media based on people appearing in them, places they were shot at, and more.
Secure your home with private video surveillance
Keep people and property safe with a powerful and intuitive suite of surveillance solutions. Synology Surveillance Station works with a wide range of IP cameras and even enables you to monitor your home from anywhere through a handy mobile app.
