Versatile, powerful and compact storage server
Synology DS118 comes with a new 64-bit quad-core processor, delivering excellent data transfer speed and 10-bit 4K H.265 video transcoding on the fly.
Ultimate file management and sharing
File Station is a web-based, fast and secure management tool built to allow easy, drag-and-drop operation without requiring any complex setup on Mac or PC. Advanced search and filtering tools allow for easy organization and sharing of files with just a link. Supports SMB, FTP, AFP, NFS, WebDAV, compatible with any environment.
Synchronize files across your devices
Cloud Station Suite provides real-time data synchronization across all your devices, such as computers, mobile devices, and other Synology NAS whenever a file is modified. “Intelliversioning” keeps the most important file versions to better utilize storage space.
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. QuickConnect allows you to connect via a simple customizable address (e.g. https://customID.quickconnect.to), so that you can instantly access media and work files on any Windows/Mac/Linux computer, laptop, or mobile device without additional charge.
4K Multimedia Server
Access and stream your favorite 4K content anywhere, anytime. DS118 supports 10-bit 4K H.265 online transcoding. With Video Station and DS video, you can convert and play 4K videos from any computer, mobile device, or other media players that don’t support Ultra HD formats.
