1. Understanding Synology NAS and Plex

Synology is one of the more prominent brands in the Network Attached Storage game. These handy devices allow you to centralize data storage in one place. Even better, you can configure your NAS for access virtually anywhere.

However, a Synology NAS is more than just a storage device; it’s a hub where you can manage files, share content, and even run various applications. The specific features will vary depending on which Synology NAS model you choose since they come in a broad range. 

Combining Plex With a Synology NAS

One of the many applications you can run on your Synology NAS is Plex. It’s a media server software that organizes your media libraries and streams them to any device, including your TV, smartphone, or computer. You can handle anything from mobile formats to 4K streaming with Plex.

When Plex is installed on a NAS system like Synology, it transforms your NAS into a powerful media server. Your media files stored on the Synology NAS can be easily accessed and streamed using the Plex app on any device, anywhere in the world, as long as it’s connected to the internet.

Running Plex on your Synology NAS offers several advantages;

  • You can centralize your media library, saving space and reducing redundancy
  • It allows you to access your content anytime and from anywhere.
  • Synology reliability ensures a smooth and stable streaming experience.
  • The convenient interface makes management and organization simple.

Pro Tip! You can use a seedbox to build up your media content remotely with high-speed downloads/uploads and ultra-privacy. You can then transfer your files to your NAS via secure FTP. A remote seedbox will help you reduce the load on your home internet, optimize NAS storage, serve as content backups and more. You can also run Plex Media Server on your seedbox or Synology NAS and then remote-share your content with other Plex clients.

4. How to Optimize Plex Performance on Synology NAS

One of the most vital things you must remember is that most NAS devices are less powerful than PCs. Because of that, getting Plex streaming well on your Synology NAS sometimes takes tweaking.

Here are some ways to do this;

Use Wired Connections

Utilize Ethernet cables to connect your Synology NAS and streaming devices. Wired connections offer enhanced stability and speed compared to wireless connections, ensuring uninterrupted streaming.

This can be somewhat frustrating since you’ll be tied to the NAS (quite literally). Think of it as a troubleshooting step. If you can stream well with a wired connection, it may be time to update your wireless router or the WiFi interface of your device.

Activate Hardware Transcoding

If supported by your Synology NAS, activate hardware transcoding in Plex. This feature utilizes the NAS hardware to convert media formats, relieving the CPU and ensuring smooth streaming even for high-definition content.

Properly Format Your Media Files

Plex works best with media file formats that it knows and are standardized. If it encounters media it can’t handle correctly; Plex will try to convert it to something it can handle. This conversion takes a lot of power and may cause stuttering during the streaming process.

To avoid this, convert your media files to formats supported by Plex and your streaming devices. Using compatible formats minimizes transcoding demands, ensuring quicker access and smoother streaming.

5 Troubleshooting Common Issues

While getting Plex to run on your Synology NAS is straightforward, unfortunately, bad things sometimes happen for unknown reasons. Consequently, in this final section, we will cover some common issues you might encounter. Furthermore, we’ll provide solutions to resolve them.

a. Problem: Plex Server Not Accessible

  • Ensure your Synology NAS is powered on and connected to the network.
  • Check your internet connection and ensure your device is connected.
  • Verify that you are using the correct Plex account credentials.

b. Problem: Media Not Loading or Buffering

  • Ensure your media files are in supported formats.
  • Check the network connection and bandwidth; upgrade if necessary.
  • Restart your Synology NAS and the device you are streaming on.

c. Problem: Remote Access Issues

  • Ensure remote access is enabled in your Plex settings.
  • Check your router settings and ensure the necessary ports are open.
  • Consult Plex’s official documentation for detailed remote access troubleshooting.

6. Conclusion

Investing the time and effort to set up and optimize Plex on your Synology NAS properly is worth the exceptional, streamlined, and high-quality media streaming experience you will enjoy. After all, while your setup serves as a media server, it’s also essentially a gateway to endless entertainment.

So don’t rush the process. Think of the experience as crafting a personalized media landscape. Ensure that every beat of your favorite song, every frame of that cherished movie, and every pixel of those memorable photos is delivered to you with precision and quality.

Here’s a friendly tip! Use a seedbox for fast, private downloads and uploads to build up your media collection remotely. Then, securely transfer your files to your NAS via FTP.

A seedbox reduces the load on your home internet, optimizes NAS storage, and serves as a backup. You can even run Plex Media Server on your seedbox or Synology NAS to share your content with other Plex clients remotely.
