SHR maximizes the data capacity of your RAID when different sizes of HDDs are used. Calculate your RAID needs.

Easy Management

For novice users who have no technical background and still want to protect their data using RAID technology, a convenient installation wizard will guide you through all the steps during your first installation.

Scalability

You can add new disks on the fly in Storage Manager with a simple click. Learn more about SHR.

Flexibility

While creating a volume, you can plan ahead and leave empty and unallocated space for future usage.

Easy file access with QuickConnect

Access files on your Synology NAS over the Internet without the hassle of setting up port forwarding rules, DDNS, or other complicated network settings.
