Verdict: The CWWK X86-P6 is an appealing ultra-small, quiet, low-power NAS and server platform with four M.2 2280 slots and dual 2.5GbE. However, its four SSDs connect through a shared PCIe Gen3 x4 uplink and operate at roughly Gen3 x1 per drive. That makes it a compact solid-state storage appliance—not a four-drive high-speed NVMe array. For ordinary NAS duties, the cheaper Intel N150 version is often the better value; the eight-core N355 is worth considering mainly for heavier virtualization and mixed server workloads.
ServeTheHome reviewed two nearly identical CWWK X86-P6 systems on August 7, 2025: a green model with Intel’s eight-core N355 processor and a black model with the four-core N150. Both target buyers who want a tiny x86 appliance for file serving, backups, containers, Proxmox, or a portable media server rather than a conventional desktop or enterprise NAS.

The concept is strong. Four internal M.2 drives provide silent, compact storage, while two Intel i226-V 2.5GbE ports offer substantially more network capacity than basic 1GbE appliances. But the platform has important compromises: limited USB connectivity, difficult memory access, no 10GbE, uncertain seller bundles and support, and a storage topology that limits each SSD to a PCIe Gen3 x1 link.
What is the CWWK X86-P6?
The X86-P6 is best understood as a barebones x86 mini-server with NAS-oriented storage expansion. It is not necessarily a turnkey appliance with a proprietary operating system, polished management interface, or enterprise support contract. Depending on the seller and bundle, it may arrive with memory, SSDs, a power adapter, and a USB cooling fan—or as a barebones chassis requiring you to supply those parts.

The platform can run operating systems such as Proxmox VE, TrueNAS SCALE, OpenMediaVault, Unraid, Debian or Ubuntu with Docker or Podman, and Windows where appropriate. ServeTheHome used Proxmox VE 8.4 and later upgraded the system to Proxmox VE 9. That demonstrates practical compatibility in the tested configuration, not formal vendor certification.
Typical uses include:
- A small SMB or NFS file server.
- A backup target for PCs and other servers.
- A compact all-flash NAS without mechanical-drive noise.
- A travel or field media server.

Specifications and connectivity
| Feature | CWWK X86-P6 N355 review configuration |
|---|---|
| Processor | Intel N355, eight cores |
| Memory | DDR5 SODIMM; 16GB is a practical baseline, with 32GB configurations observed |
| Storage | Four M.2 2280 SSD positions |
| Storage topology | Shared PCIe Gen3 x4 uplink, split into approximately Gen3 x1 per SSD |
| Networking | Two 2.5GbE ports using Intel i226-V controllers |
| Video | Two HDMI outputs |
| USB | Two USB 3 ports |
| Power | 12V DC; the reviewed N355 system used a 12V/8A, 96W adapter |
| Cooling | Internal processor fan; a top-mounted USB fan was used in the reviewed system |
| Tested operating systems | Proxmox VE 8.4, later upgraded to Proxmox VE 9 |
The rear and front I/O is functional but sparse. Dual 2.5GbE can be used for separate networks, independent services, routing, or link aggregation where the switch and operating system support it. Two ports do not automatically provide 5Gbps to one client: a single transfer normally remains limited by one link, and aggregation depends on the protocol, switch, client configuration, and workload.
Two USB ports are a more immediate limitation. A keyboard, mouse, installation drive, external disk, or USB fan can quickly consume all available ports. The HDMI outputs are useful for local installation and troubleshooting, but they do not turn the X86-P6 into a particularly practical desktop replacement. The use of a 12V barrel-style input rather than USB-C Power Delivery also makes it less convenient for travel.
The four M.2 slots are not four full-speed NVMe connections
This is the most important technical detail in the entire platform. The four-drive riser connects to the system through one PCIe Gen3 x4 connection, which is divided across four drive connections:
Intel platform PCIe Gen3 x4
|
four-drive riser
/ | |
Gen3 x1 Gen3 x1 Gen3 x1 Gen3 x1
SSD 1 SSD 2 SSD 3 SSD 4As ServeTheHome’s internal inspection explains, each SSD receives approximately a PCIe Gen3 x1 link rather than the PCIe x4 connection commonly associated with a standalone NVMe drive. Four drives also share the upstream bandwidth, so they cannot all deliver independent full-speed NVMe performance.
That does not make the design useless. A Gen3 x1 connection can still be adequate for file serving, backups, containers, and many light virtualization workloads. The drives offer capacity, low noise, low power consumption, and no moving parts. They can also be arranged for redundancy in software such as ZFS, Linux mdraid, or the storage layer supplied by another operating system.
It does mean that premium Gen4 and Gen5 SSDs are generally poor value here. Select drives for price, endurance, power efficiency, thermals, and compatibility. A lower-cost Gen4 SSD can still be sensible if it costs about the same as a Gen3 model, but paying a large premium for headline sequential speed is difficult to justify.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Internal layout and upgradeability
Drive installation is relatively accessible. Removing the top panel exposes the M.2 area and separate riser board. The SSDs are held with screws rather than tool-free latches, and thermal pads are supplied in the reviewed systems.
Memory access is much less convenient. The DDR5 SODIMM slot sits beneath the drive and riser assembly, so upgrading memory requires substantial disassembly. Buyers choosing a barebones unit should install the intended memory before completing the build rather than treating a later upgrade as a quick maintenance task.
Motherboard-level repair is not aimed at casual users. ServeTheHome specifically warns that the power button must be seated correctly before reinstalling the motherboard. A misplaced connection can turn reassembly into a troubleshooting exercise.
Intel N355 versus N150: is the premium worthwhile?
The N355 has eight cores compared with four on the N150, so it is easy to assume that it should deliver roughly twice the performance. The tested CWWK implementation does not support that conclusion.
ServeTheHome found that the N355 can boost to higher power briefly but settles near an approximately 9W sustained SoC power level. As a result, its advantage over the N150 was considerably smaller than the core count suggests. This does not mean the N355 is universally slower than the N150; it means its extra cores do not automatically translate into proportional performance in this chassis and power configuration.
Choose the N150 when:
- Your workload is mainly SMB, NFS, backups, and light file services.
- You plan to run only a few containers.
- The N355 price premium is substantial.
- You care more about purchase price and power efficiency than peak multicore performance.
- You will use one or two SSDs and do not need many simultaneous services.
Choose the N355 when:
- You expect several virtual machines or many concurrent containers.
- ZFS and other storage services will run alongside compute-heavy applications.
- You will transcode media while handling other server tasks.
- The price difference is small.
- You are prepared to validate sustained performance and cooling yourself.
The BIOS reportedly includes power-related options, but changing them does not guarantee a particular performance level, thermal result, or reliability outcome. The practical buying rule is simple: do not pay for the N355 solely because it has twice as many cores.
NAS, ZFS, and Proxmox suitability
For a simple NAS, 16GB of DDR5 SODIMM memory is a sensible starting point. A 32GB configuration may be useful for several VMs or memory-hungry services, but compatibility depends on the actual module, firmware, and seller configuration. Do not assume that every advertised capacity will work identically in every revision.
For ZFS, adequate memory is only one part of the design. Choose a sensible vdev layout, monitor drive health, test the array under sustained load, and maintain backups. Four drives can be arranged as mirrors, a RAID10-like pool, RAIDZ1, or another layout depending on the operating system. Each choice changes usable capacity, fault tolerance, rebuild behavior, and performance.

Four 4TB SSDs provide 16TB of raw capacity—not 16TB of usable space. A mirror or RAID10-style layout sacrifices approximately half the raw capacity before filesystem overhead. Parity layouts have different capacity and rebuild trade-offs. RAID improves availability against some drive failures; it is not a backup.
The X86-P6 is a good Proxmox experimenter’s node, particularly when the goal is a compact x86 host with integrated storage. It is less compelling as the foundation of a large virtual infrastructure where predictable support, remote management, expansion, and long-term firmware availability matter more than size and price.
Power consumption, thermals, and noise
The following figures are measurements reported by ServeTheHome, not universal specifications. The N355 wall figures included four SSDs and a USB cooling fan, while the N150 setup used fewer drives, so the configurations are not directly equivalent.
| Measurement | Reported result |
|---|---|
| N150 SoC idle | About 2.2W |
| N150 SoC burst | About 8.6W |
| N150 SoC sustained after roughly 30 seconds | About 6.1W |
| N355 SoC idle | About 3.2–3.4W |
| N355 SoC burst | About 12W |
| N355 SoC sustained after roughly 30 seconds | About 8.6–9W |
| N150 wall idle, one SSD, no USB fan | About 10–11W |
| N150 wall burst | About 22–23W |
| N150 wall sustained | About 17–18W |
| N355 wall idle, four SSDs plus USB fan | About 12–13W |
| N355 wall burst | About 30–31W |
| N355 wall sustained | About 24.5–26W |
| Noise without USB fan | About 36–37dBA |
| Noise with USB fan | About 38–39dBA |
ServeTheHome’s measurements show why SoC power and wall power must not be confused. SSD count, memory, fan use, workload, room noise, power settings, and drive efficiency all affect the result. The X86-P6 is quiet rather than silent, and a USB fan can increase both cooling and noise while consuming one of the two USB ports.
Recommended Free Tools
The N355’s sustained power behavior is also central to the buying decision. Its higher burst ceiling can help short tasks, but the sustained limit reduces the benefit of its additional cores during longer workloads.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Reliability questions and owner reports
The review itself does not establish a confirmed design defect, but comments attached to the ServeTheHome article describe issues that prospective owners should take seriously. Some commenters reported RAID10 failures during benchmarking with four high-performance SSDs, drives temporarily disappearing from BIOS, and more stable behavior with only two drives. Others reported higher-than-expected idle power in TrueNAS SCALE and speculated about power delivery or PCIe-switch temperatures.
These are anecdotal owner reports, not independently verified findings, and the suspected causes were not established by ServeTheHome. They should not be treated as proof that every X86-P6 will fail. They are, however, good reasons to validate a particular unit before trusting it with important data.
- Use efficient SSDs instead of flagship, high-wattage models.
- Burn in all four drives under sustained simultaneous read and write load.
- Monitor SSD temperatures and SMART or NVMe health data.
- Test the exact memory module and capacity you plan to use.
- Use a UPS or a clean, correctly rated 12V power source.
- Keep current backups outside the X86-P6.
- Do not assume that electrical compatibility guarantees stable four-drive operation under load.
- Confirm whether the USB fan is included and whether the selected SSDs actually require additional airflow.

ServeTheHome described some configurations as around or below $200 before storage during the review period, but pricing and discounts vary. That figure should not be treated as a guaranteed current price. Four SSDs can easily cost more than the computer itself, and an expensive preconfigured bundle may remove much of the X86-P6’s value advantage.
The four-drive ceiling also matters. A four-drive pool may be enough for a compact home server, but it offers less capacity and expansion headroom than six- or eight-drive all-flash appliances. For context, ServeTheHome’s TerraMaster F8-SSD Plus coverage describes a larger eight-M.2 system with 10GbE. Its historical review-period pricing was several times higher, so it serves a different buyer rather than being a direct low-cost substitute.
Who should buy the X86-P6?
| Buyer profile | Recommendation |
|---|---|
| Low-cost four-drive home NAS | Consider the N150 first |
| Proxmox host with several VMs | Consider the N355, but validate sustained performance |
| Travel NAS or portable server | Good fit if 12V power and limited I/O are acceptable |
| 10GbE workstation storage | Poor fit |
| Large media archive | Poor fit unless four-drive capacity is sufficient |
| Enterprise or business-critical deployment | Poor fit unless support and warranty are independently acceptable |
| User with spare M.2 drives | Good candidate, subject to power and thermal testing |
| Buyer seeking maximum Gen4/Gen5 SSD performance | Poor value |
Buying checklist
Marketplace listings are not necessarily standardized. Before ordering, verify:
- The exact CPU: N150 or N355.
- Whether memory is included, and its capacity and type.
- Whether SSDs are included.
- The power adapter’s voltage, current rating, plug, and regional compatibility.
- Whether the USB fan is included.
- Chassis color and board revision, if relevant.
- Warranty, return terms, shipping origin, taxes, and seller reputation.
- Whether the listing describes a barebones unit or a complete system.
Final verdict
The CWWK X86-P6 succeeds because it puts four solid-state storage positions, x86 compatibility, dual 2.5GbE, and low-power operation into an unusually small chassis. It is a compelling platform for a quiet home NAS, backup server, travel appliance, or lightweight Proxmox node.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsIts limitations are equally important. The four drives share a PCIe Gen3 x4 connection and run at approximately Gen3 x1 each, the I/O is minimal, memory upgrades are awkward, support is seller-dependent, and the N355’s sustained power cap prevents its eight cores from delivering the expected premium. For most ordinary NAS workloads, buy the N150 if the price difference is meaningful. Choose the N355 when you have a real need for additional concurrent compute and the premium is small enough to justify testing the platform’s sustained behavior.
In short, the X86-P6 is best viewed as a compact, quiet, low-cost four-drive server—not as a miniature high-performance NVMe array or a fully supported enterprise NAS.
