Supporting near-instantaneous snapshot technology and real-time 4K video transcoding, DS620slim is an all-around file management solution that fulfills professionals’ needs of advanced data protection and high-quality media streaming.

Remain classic while shrinking footprint

The mini 6-bay design keeps DS620slim classic and saves deployment space. With six 2.5" drive support, DS620slim is able to boost performance by installing SSDs.

Ultimate file management and sharing

File Station is a web-based, fast and secure management tool built to allow easy, drag-and-drop operations without requiring any complex setup on Mac or PC. Advanced search and filtering tools allow for easy organization and file sharing. For complete compatibility, DS620slim supports the following protocols: AFP, FTP, iSCSI, NFS, SMB, and WebDAV.

Synchronize files across your devices

Cloud Station Suite provides real-time data synchronization across all your devices and other Synology NAS. "Intelliversioning" keeps the most important file versions to better utilize storage space. 

4K Multimedia Server

Access and stream your 4K media content anytime and anywhere. DS620slim supports 4K H.264/H.265 online transcoding via Video Station and DS video, allowing 4K videos to be converted and played on the fly on other computers, smartphones, and media players that originally do not support Ultra HD formats.
