Versatile NAS server for centralized file storage andreal-time 4KH.265video transcoding
Synology DS418 comes with a new 64-bit quad-core processor, delivering excellent data transfer speed, large storage volume management, and 10-bit 4K H.265 video transcoding on the fly.

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.

Real-time collaboration on your private cloud
Office is a collaboration package combining the convenience and usability of public clouds with the data privacy and security guaranteed by private clouds. It allows you to work seamlessly together on documents and spreadsheets in a protected environment.

4K Multimedia Server
Access and stream your favorite 4K content anywhere, anytime. DS418 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 supportUltra HD formats.

Synology Hybrid RAID (SHR) technology
Storage management is easy with Synology Hybrid RAID (SHR) technology. SHR is an automated RAID management system allowing you to easily create and expand storage volumes and migrate RAID types without requiring details on RAID. SHR provides 1 to 2-disk redundancy to safeguard your data during drive failures.

Cost-effective
SHR maximizes the data capacity of your RAID when different sizes of HDDs are used.

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.

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. QuickConnect allows you to connect via a secure, customizable address, so that you can instantly access media and work files on any Internet-connected device with no additional charge.
