Mini PC NAS N355 5M.2 Nvme Pocket NAS Small PC - Compact 4K Mini PC

In this review the Mini PC NAS N355 5M.2 Nvme Pocket NAS Small PC is evaluated as a space-saving, storage-focused micro desktop for small offices and home lab users. The bottom line: this unit stands out for massive NVMe expansion via five M.2 lanes and four 2.5GbE Intel NICs, making it a practical choice when high-speed local storage and multiport networking matter more than raw CPU power. It is best for those who need a quiet, low-power NAS or router appliance with dual 4K display support rather than a heavy-duty workstation.

Key Features

• 5M.2 NVMe expansion: Five M.2 2280 NVMe lanes (split via adapter boards) provide abundant high-speed internal storage for multi-drive NAS setups without large 3.5 in bays.
• Quad 2.5GbE networking: Four Intel i226-V 2.5G Ethernet ports deliver elevated LAN throughput for small office file sharing, virtualization, or bonded storage links.
• DDR5 memory support: A single SO-DIMM DDR5 slot supports up to 48GB at 4800MHz (compatible with faster modules), letting light server tasks and caching run smoothly.
• Low-power N100 processor: The Alder Lake-N N100 CPU (6MB cache, up to 3.4GHz, 6W TDP) keeps energy use and noise down while handling web services, file serving, and light graphics tasks.
• Dual 4K video output: HDMI 2.1 plus DP 1.4 support 4096 x 2160 at 60Hz for a compact desktop or console display while the system runs as a NAS or firewall.
• Included accessories: Ships with two free M.2 adapter boards, two WiFi-to-M.2 adapters, two small fans and a screwdriver to aid assembly and cooling customization.

Who It's For

The Mini PC NAS N355 suits small business owners, home lab enthusiasts, and network professionals who need concentrated NVMe capacity and multiple 2.5GbE ports in a compact chassis. It works well as a QNAS/router/firewall appliance or as a compact NAS for fast local backups and media serving while keeping power consumption low.

It is less suitable for users who require heavy CPU throughput for video encoding, large virtual machine farms, or high-end gaming; the N100 is efficient but not a workstation-class processor. Also, those needing many 3.5 in HDD bays or integrated 10GbE should look at larger dedicated chassis.

Pros & Cons

Pros

• Exceptional NVMe expandability with five M.2 slots via adapter boards for high-performance storage arrays.
• Multiple Intel i226-V 2.5GbE ports provide real-world network speed improvements over gigabit for file transfers.
• Low-power N100 processor and DDR5 memory support keep operating costs and heat low for always-on applications.
• Compact footprint and dual 4K display outputs add desktop flexibility while functioning as a headless NAS or router.

Cons

• Limited CPU performance for heavy compute or many simultaneous VMs due to the N100's low TDP design.
• Single SO-DIMM slot limits upgrade paths compared with larger systems that offer dual-channel memory.

Our Verdict

The Mini PC NAS N355 is a strong choice for users who prioritize internal NVMe capacity and multiport 2.5GbE connectivity in a tiny, energy-efficient package. It delivers excellent value as a compact NAS, router, or small office server where low power draw and fast local storage matter more than multi-core CPU performance.

Frequently Asked Questions

Can this unit boot from an NVMe drive?
Yes. The TF card holder and M.2 NVMe slots support system boot from NVMe storage when configured in BIOS.

Does it include fans and adapter boards?
Yes. The package includes two small fans, two M.2 adapter boards and two WiFi-to-M.2 adapters to enable the M.2 expansion.

Is the N100 powerful enough for a small office NAS?
For file serving, backups, and light services the N100 is adequate thanks to low power and fast NVMe storage, but heavy virtualization or CPU-bound tasks will need a stronger CPU.
