The Scalable Synology DS918 + NAS

The NAS comes with professional features which will satisfy all of your productivity and efficiency requirements for small as well as medium-sized companies. At the same time, it costs only a fraction of the price compared to large servers. With this NAS, you will not have to worry about the cost of its acquisition, operation, and its software. Synology will provide you with everything at once and with a light, easy administration system. As a classic server, it is scalable and the device can be extended with the 5-disc DX517 expansion unit with up to 2 M.2 NVMe SSD drives. The Synology DS918 + DiskStation will also meet the growth in data services.

Data protection and integrity with Btrfs

The Synology DiskStation DS918 + contains the new generation Btrfs file system which has many tools to prevent data corruption. The Btrfs file system holds two copies of metadata on the volume, allowing you to recover data in the event of hard drive corruption or bad sectors. Common file volume, errors with files are detected automatically. However, Btrfs creates the checksums for each read operation so that the error is detected immediately and auto-correction occurs. The snapshot features allow you to make a copy of the entire shared folder or system. This way, in the event of a database loss or corruption, you can quickly recover data back to the moment the image was taken.

Services at the tip of your finger with the Synology NAS

The Synology DiskStation DS918 + NAS has a sleek DiskStation Manager (DSM) browser operating system. With its clear, manageable environment, you can customise all of the services and even add different packages to it to customise it to your needs. To protect important data and other assets, DSM offers new management and security tools, so that the Synology NAS can serve as a strategic network centre. With Snapshot Replication, DSM offers almost continuous data protection and replication to multiple sites for a more comprehensive level of protection. In addition, Synology's Hyper Backup can now back up multiple versions to all of the types of target locations.


Get easy file access over the Internet without bothering to set up port forwarding rules, DDNS, or other complicated network settings. QuickConnect lets you connect to your NAS securely from any device that is connected to the Internet.

Use your NAS as a secure business cloud

Is it important for you to keep your files at hand no matter what device you use? With Cloud Station, synchronising files between different devices and creating your own private cloud is easier than ever before. Business security is covered by two-step verification, group authorisation (local and VPN), and encryption. If you are worried about accidental deletions or file changes, it can also save up to 32 older versions of each file. In addition, Cloud Sync offers a more accurate level of synchronisation control and backup of your files from your Synology DiskStation DS918 + onto your external cloud service host.
