In many edge computing, NAS, and small server deployments, typical mini PCs are limited by two things:
insufficient network interfaces and inflexible storage design.
The Qotom Q31100G4 series is built around these two aspects. Instead of focusing purely on CPU performance, this platform is designed as a combination of networking and storage capabilities.

4 × 2.5G LAN: Designed for Network Segmentation
The Q31100G4 comes with 4 Intel I226-V 2.5GbE ports, which is uncommon for standard mini PCs.
This allows the system to be used as more than just a single host. In practical deployment, these ports are often assigned different roles:
- WAN (Internet access)
- LAN (local network)
- Dedicated storage network
- Management or additional network
With this setup, storage traffic and general network traffic can be separated, which improves overall stability—especially in NAS or router-integrated scenarios.

4 × M.2 NVMe: Flexible Storage Layout
Unlike typical mini PCs with limited storage options, the Q31100G4 provides four M.2 SSD slots with different PCIe lanes:
- 2 × PCIe 3.0 x2
- 2 × PCIe 3.0 x1
This is not just about adding more storage, but about organizing storage roles:
- System drive
- Data drives
- Cache or log drive
With this structure, the system can handle multiple workloads—such as file services, containers, and background tasks—without heavy I/O conflicts.

Available Configurations
The Q31100G4 series is available in three main configurations:
Q31111G4 (Celeron 6305)
- 2 cores / 2 threads
- 1.8 GHz
- 15W TDP
Suitable for basic NAS, lightweight routing, and low-power deployments.
Q31131G4 (Core i3-1115G4)
- 2 cores / 4 threads
- Base 3.0 GHz
Offers better responsiveness and can handle NAS + light services (e.g., Docker or small applications).
Q31151G4 (Core i5-1135G7)
- 4 cores / 8 threads
- Up to 4.2 GHz
A balanced option for multi-service environments:
- NAS + router integration
- Multiple containers
- Edge computing workloads
Why It Stops at i5
The Q31100G4 has a compact form factor (142 × 210 × 39 mm) with active cooling.
In this size range, moving to higher-power CPUs (such as i7) introduces:
- Higher thermal output
- Increased fan noise
- Reduced long-term stability
Since this platform is typically used for 24/7 operation, stability and thermal control are prioritized over peak performance.
Typical Use Cases
With its multi-LAN and multi-storage design, the Q31100G4 fits well in:
- NAS servers
- Router / firewall systems
- Edge computing nodes
- Small virtualization or container platforms
Final Note
The Q31100G4 is not just a mini PC—it is a compact platform built around network segmentation and flexible storage architecture.
Its value comes from how these components work together, rather than raw CPU performance alone.
