Which one should you choose?
Choose VNOPN Fanless 4-Port Firewall Mini PC if
- You need the lowest possible power draw for a always-on network node.
- You prefer DDR3 memory compatibility or have existing DDR3 constraints.
- You want a slightly more compact weight for VESA mounting.
Choose Sharevdi Fanless 2.5GbE J4105 Firewall Mini PC if
- You require faster CPU performance for higher traffic routing or virtualization.
- You want more built-in storage for logs or packages.
- You plan to upgrade RAM beyond 8GB using DDR4 modules.
Verdict: The Sharevdi is the better choice for most users due to its newer J4105 processor, DDR4 memory, and larger storage capacity. These specs provide better performance for modern firewall tasks and virtualization. Choose the VNOPN only if minimizing power consumption to 6W is your absolute priority.
VNOPN vs Sharevdi Firewall Specs
Processor Performance
The Sharevdi uses an Intel J4105 quad-core processor with a 10W TDP, while the VNOPN relies on an older Intel J3710 at just 6W. The J4105 offers a larger 4MB L2 cache compared to the J3710’s 2MB. Both chips support AES-NI for hardware-accelerated encryption, which is critical for firewall throughput. The Sharevdi’s higher thermal design power allows for slightly more sustained performance under load. For network routing tasks, the J4105 generally provides better efficiency and speed. The VNOPN’s lower power draw is notable, but the processing gap favors the Sharevdi for heavier network duties.
Memory Technology
Both mini PCs come equipped with 8GB of RAM, but they use different memory standards. The Sharevdi utilizes DDR4 RAM, which is faster and more power-efficient than the DDR3 found in the VNOPN. The Sharevdi also supports a maximum upgrade to 16GB, whereas the VNOPN is capped at 8GB. This difference matters for running virtualization software or multiple network services simultaneously. If you plan to expand your home lab later, the Sharevdi offers more headroom. For basic firewall routing, both provide adequate memory, but the technology gap gives Sharevdi the advantage.
Storage Capacity
Storage options differ between the two units. The Sharevdi includes a 240GB mSATA SSD, while the VNOPN comes with a 128GB mSATA SSD. Both systems support upgrades up to 512GB via the mSATA slot, but neither supports traditional HDDs. The larger base storage on the Sharevdi allows for more logs, updates, and local files right out of the box. This is useful for firewall appliances that record significant network traffic data. The VNOPN’s smaller drive may require earlier upgrades for heavy logging use cases.
Networking Ports
Both devices feature four 2.5GbE Intel i226-v LAN ports, providing identical high-speed connectivity options. This configuration is ideal for modern home networks or small offices requiring multi-gigabit throughput. Both units also include two USB 3.0 ports for peripheral connections. The VNOPN lists support for optional Wi-Fi and 3G/4G module expansion, which the Sharevdi data does not explicitly mention. However, the core wired networking capabilities are exactly the same. For standard firewall deployments, this aspect is a complete tie.
Cooling Design
Both mini PCs employ a fanless design with aluminum alloy chassis for passive cooling. This ensures silent operation and reduces maintenance needs for 24/7 network use. The VNOPN is rated for 6W TDP, while the Sharevdi is rated for 10W. Despite the higher power draw, the Sharevdi is designed to withstand ambient temperatures up to 60°C. Both units are compact and weigh approximately 500g, making them easy to mount with the included VESA kits. The cooling approach is functionally identical for most indoor environments.
Which Mini PC Fits Your Network Needs
Users needing maximum routing throughput
The Sharevdi uses the Intel J4105 processor, which is faster than the VNOPN's J3710. It also includes DDR4 RAM instead of older DDR3. This combination provides better performance for heavy firewall tasks. The 10W TDP supports higher sustained speeds. You get 240GB of storage for logs. Choose this if raw processing power matters most for your network traffic.
Users prioritizing energy efficiency
The VNOPN runs on a 6W TDP Intel J3710 chip. This is lower than the Sharevdi's 10W requirement. It uses a fanless aluminum design for silent operation. The unit weighs approximately 500g and fits small spaces. You get 8GB of RAM and 128GB of storage. Select this model if you want the lowest possible power draw for continuous 24/7 network uptime.
Users wanting more storage capacity
The Sharevdi includes a 240GB mSATA SSD, which is larger than the VNOPN's 128GB drive. Both use mSATA slots and do not support HDDs. The extra space helps store more system logs and data. You also get the newer J4105 processor. Pick this option if you need more room for your firewall records and open-source operating system files.
