DiskStation DS418
Powerful 4-bay NAS for home and office users

Features:

Versatile NAS server for centralized file storage and real-time 4K H.265 video 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, 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.

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 via Video Station and DS video, allowing 4K videos to be converted and played on your computers, mobile devices, or other media players that don't support Ultra 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 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.
