Synology Network Upgrade Module adds 1x 10GbE RJ-45 - Faster NAS

Our review of the Synology Network Upgrade Module finds it is a straightforward, cost-effective way to add 10GbE to compatible Synology systems. Ideal for small business and advanced home NAS users, the module's single biggest advantage is that it delivers clear, real-world speed gains for large file transfers and concurrent tasks with minimal fuss. Installation is simple, and compatibility with mixed-speed RJ-45 networks means this module slots into many existing environments without forcing a full network overhaul.

Key Features

• 10GbE connectivity: Adds a single 10GbE RJ-45 port so large video files and backups move much faster across the LAN.
• Multi-speed support: Works with 10/5/2.5/1GbE networks to ensure compatibility with common switches and cabling without extra adapters.
• Easy installation: Designed for quick fitment into Synology systems so users can upgrade performance with minimal downtime.
• Optimized for Synology: Built to provide maximum performance and reliability when paired with supported Synology NAS models.
• Long warranty: A 5-year warranty gives buyers confidence in durability and long-term value.

Who It's For

The module is best for creators and small teams who regularly move multi-gigabyte video files, run concurrent backup jobs, or host many simultaneous users accessing large datasets. It is also a sensible upgrade for home power users who want to future-proof a compatible Synology NAS without replacing their network switch immediately.

Those who should look elsewhere include users with NAS models that are not listed as compatible on Synology's website, or people who need more than one 10GbE port or fiber connectivity; in those cases a different network card or external solution may be a better fit.

Pros & Cons

Pros

• Noticeable performance boost for large transfers and simultaneous tasks, as reported by customers praising the speed.
• Very simple install and often plug-and-play with Synology systems, matching user comments about ease of installation.
• Works across mixed-speed RJ-45 networks, giving flexibility with existing cabling and switches.
• Backed by a 5-year warranty, which adds confidence for long-term use.

Cons

• Only a single 10GbE port is provided, so environments needing multiple 10GbE uplinks will need additional hardware.
