⚡ Network Connectivity & Internet Performance

The Synology DS223j is designed for fast and stable network performance, ensuring smooth data access, media streaming, and surveillance monitoring. Here’s what you need to know about its internet connectivity:

🔌 Connecting the DS223j to the Internet

  1. Ethernet Connection – The NAS features one Gigabit Ethernet port (1GbE). Simply connect it to your router or switch using an RJ-45 Ethernet cable.
  2. DHCP & Static IP – By default, the NAS obtains an IP address automatically (DHCP), but you can set a static IP for better control.
  3. Port Forwarding & Remote Access – With QuickConnect or DDNS, you can access your NAS securely from anywhere in the world.
  4. LAN & WAN Speed – The 1GbE connection offers speeds up to 125 MB/s, ideal for media streaming, backups, and file sharing.

🚀 Can You Upgrade the Network Speed?

The DS223j does not support 2.5GbE or 10GbE, which means its network speed is capped at 1Gbps. However, for most home users and small businesses, 1GbE is sufficient for streaming, backups, and cloud access.

💡 Tip: If you need faster speeds, consider using Link Aggregation (with a compatible switch and multiple NAS devices) or upgrading to a higher-end Synology NAS with 2.5GbE support.

🌍 Benefits of a NAS with Internet Access

🔹 Remote Access – Work on files from anywhere via Synology Drive, DS File, or QuickConnect

🔹 Automatic Photo Backup – Sync photos from your phone to your NAS, just like Google Photos.

🔹 Media Streaming – Enjoy 4K video playback on smart TVs, PlayStation, Xbox, and more via Plex or Emby.

🔹 Surveillance Monitoring – View and manage IP camera footage remotely with Surveillance Station.

🔹 Private Cloud Hosting – Host your own cloud storage without third-party subscriptions.

🚀 High-Speed Caching: The Key to Smooth Performance

The DS223j uses a temporary storage cache to speed up file access and data transfer, reducing load times for frequently used files. This is especially useful for:

  • Streaming 4K videos without buffering 🎬
  • Faster file access when editing large documents 📂
  • Improving responsiveness when running multiple apps

Although RAM is non-expandable, Synology’s efficient DiskStation Manager (DSM) ensures smooth performance for home and small office users.


🎥 Surveillance System: Secure Your Home & Business

One of the most powerful features of the DS223j is its Surveillance Station integration. You can connect up to 12 IP cameras and manage recordings efficiently:

Customizable Storage Management – Set recordings to store for 1 month, 1 year, or until storage is full. Old footage is automatically deleted to free up space.
AI Motion Detection – Configure specific cameras to record 24/7, while others activate only when motion is detected.
Remote Access & Alerts – Receive instant notifications for unusual activities.

This makes it an affordable and reliable security solution for both homes and small businesses. 🔒


📸 Synology NAS as Your Private Google Photos & Google Drive Alternative

Instead of paying for cloud storage subscriptions, the DS223j allows you to create your own private cloud. Using Synology Photos and Drive, you can:

Automatically Backup Photos – Once you take a picture, it’s uploaded instantly to your secure NAS storage.
Sync & Share Files – Just like Google Drive, you can access your files from any device.
Strong Security – Your data is protected by password encryption and two-factor authentication.

With no monthly fees, this is a cost-effective, long-term solution! 📂🚀

🌐 Can You Host a Website on Synology NAS?

Yes, you can use Synology NAS to host a website, but with limitations:

✅ Great for personal blogs & small business sites.
