Zimaboard 2 Review – Design and Hardware

The physical build of the ZimaBoard 2 continues IceWhale’s trend of delivering thoughtfully designed hardware. The full aluminum enclosure gives the board a sturdy, premium feel, while also serving as its main cooling surface. Every port is clearly labeled, and the board layout is practical and accessible.

The PCIe slot includes a pre-cut section to accommodate longer cards, allowing for flexibility even in this small form factor. IceWhale also includes eco-friendly packaging, a detail that reflects both brand identity and attention to user experience. A cardboard insert allows users to hold the board upright alongside drives, useful for initial setup before a case is selected.

Optional accessories like a SATA adapter board with combined data/power connectors and third-party-compatible drive cages help complete the DIY experience. However, there are some practical limitations to consider: the soldered RAM means users must carefully plan for memory demands, and the internal storage, while functional, will not satisfy users looking for fast OS performance.

At the core of the ZimaBoard 2 is the Intel N150 processor, part of Intel’s Twin Lake architecture, offering four cores with a base clock that boosts up to 3.6GHz. This chip represents a significant step forward compared to the Celeron N3450 used in the original ZimaBoard, delivering better single-thread and multi-thread performance while maintaining a low 6W TDP.

Complementing the CPU is 8GB of LPDDR5x memory clocked at 4800MHz. While the use of fast memory is a welcome improvement, the limitation lies in its soldered nature—users cannot expand beyond this capacity.

This decision may be acceptable for light workloads such as running a Plex server, Docker containers, or Home Assistant, but it could become a bottleneck for users planning to run multiple VMs or resource-heavy services. The N150 CPU does support hardware virtualization and Intel AES-NI, which is essential for tasks like encrypted storage or virtual machine deployment.

In testing scenarios, the CPU delivered solid performance across typical tasks, and managed to keep up during multi-tasked environments with multiple services active. However, users with ambitions for more demanding applications will need to balance those expectations against the non-upgradable memory ceiling.

ZimaBoard 2 comes with 32GB of onboard eMMC storage, a choice that is both practical and limiting. This eMMC module is soldered to the board and is intended to house ZimaOS out of the box, giving users a ready-to-use system upon first boot. While this inclusion lowers the barrier to entry and simplifies setup for beginners, it presents performance limitations and a lack of flexibility. In testing, write speeds hovered around 35MB/s during mixed I/O operations, which is noticeably slow for tasks that involve frequent read/write cycles.

Moreover, should a user opt to install a different OS—such as TrueNAS SCALE, Proxmox, or Unraid—they would either overwrite the bundled ZimaOS or need to boot from an external USB or PCIe-based drive. Since the internal storage is neither M.2 nor socketed, it lacks the speed and modularity enthusiasts often seek in modern setups. As a result, users planning to use ZimaBoard 2 as a primary virtualization or storage server are better off supplementing it with faster storage via USB 3.1, SATA, or the PCIe slot for booting alternative OS environments. This caveat underscores a recurring theme with ZimaBoard 2: it’s well-positioned for entry-level use but requires external upgrades for more ambitious workflows.

One of the ZimaBoard 2’s most compelling features is its inclusion of two SATA 3.0 ports alongside a full PCIe 3.0 x4 slot. This greatly expands the device’s potential beyond typical SBCs, offering users a reliable way to build custom NAS setups, integrate high-speed NVMe storage, or even install networking and accelerator cards. During testing, a Synology combo card featuring two M.2 NVMe slots and a 10GbE Ethernet port was installed in the PCIe slot. The board successfully recognized all interfaces, demonstrating full PCIe compatibility and allowing throughput measurements to confirm the system could push high-bandwidth traffic.

With up to 4GB/s of bandwidth over PCIe, users can install expansion cards for fast storage, additional networking, or even compute offloading—although the small form factor means thermal and power considerations become important quickly. The SATA ports, while standard in speed, proved perfectly functional for connecting 2.5″ SSDs or traditional HDDs. IceWhale’s own accessories, like SATA power adapters and drive cages, help streamline this process, though third-party solutions work just as well.

For users aiming to transform this board into a flexible micro-server, this PCIe slot is a gateway to many possibilities and a key reason ZimaBoard 2 stands out in its category.

In terms of networking, the ZimaBoard 2 comes equipped with two 2.5GbE Ethernet ports, both powered by Intel chipsets—a choice that emphasizes reliability and driver compatibility across various operating systems. These ports are more than just a checkbox feature; they performed reliably under load and achieved full link saturation during file transfer tests and when used in conjunction with PCIe expansion.

In more advanced setups, users can configure bonding or load balancing to maximize throughput or redundancy. Additionally, there are two USB 3.1 ports for attaching external drives, peripherals, or USB-bootable OS images.

The inclusion of a Mini DisplayPort 1.2 allows for 4K video output at 60Hz, which is useful for users who want to use the board as a lightweight desktop or for initial OS installation and diagnostics—though it does require an adapter to convert to standard HDMI. Notably absent is built-in Wi-Fi or Bluetooth, which aligns with its target audience of wired-first home labs and embedded installations. Overall, ZimaBoard 2 offers a well-rounded set of connectivity options that exceed expectations for its size, with the dual 2.5GbE ports making it particularly attractive for networking-focused use cases like firewalls, proxies, or containerized gateways.

Thermal management on the ZimaBoard 2 is entirely passive, with the aluminum enclosure doubling as a heatsink to dissipate heat away from the CPU and other key components. This fanless approach results in completely silent operation, which is ideal for home or office environments where noise is a concern.

However, the trade-off is that the board’s temperature will steadily rise over time, especially in enclosed cases or cabinets with poor airflow. During idle operation, with minimal system load and attached drives in standby, temperatures hovered around 50°C after an hour, increasing slightly to 52–54°C over a 24-hour window.

Under heavier usage—including Plex playback, VM activity, active networking, and full PCIe slot utilization—the system remained thermally stable but showed significant heat buildup. Power consumption in these high-usage scenarios peaked at approximately 39–40W, which is quite efficient given the workload.

Still, users planning to run the board continuously under load are strongly encouraged to introduce active airflow or leave the system in a well-ventilated space. The all-metal build is a clever and minimalist solution, but it has practical limitations that users need to plan for—especially if operating in warmer environments or planning to enclose the unit in a tight chassis.

When put through real-world workloads, the ZimaBoard 2 delivered performance that largely aligned with its specs and design goals. File transfers over the onboard 2.5GbE interfaces reached full saturation in controlled conditions, proving the CPU and I/O subsystems are capable of pushing maximum throughput without significant bottlenecks. PCIe expansion further unlocked performance potential—especially with the Synology combo card, where simultaneous NVMe and 10GbE performance were tested. While NVMe read speeds reached up to 1.6GB/s, write speeds hovered around 500–700MB/s depending on traffic from the 10GbE port.

These variances are expected, given shared PCIe lanes and bandwidth contention, but overall results were respectable. Multimedia performance was also acceptable, with Plex running smoothly and able to stream and scrape metadata while supporting light VM usage concurrently.

In these scenarios, RAM utilization climbed past 50% and CPU usage approached 100%, but the board remained operational and responsive. It’s clear that ZimaBoard 2 is well-suited to low-to-moderate workloads, and can punch above its weight with strategic expansion. However, pushing it into more demanding territory—like simultaneous virtualization, AI inferencing, or high-speed file serving across multiple interfaces—will begin to test its limits.

The lack of active cooling makes thermal planning essential for any serious workload. But overall, the ZimaBoard 2 feels polished and reliable, with a design philosophy that caters well to its core audience of DIY server builders and edge compute experimenters.

Zimaboard 2 Review – Software

ZimaBoard 2 ships with ZimaOS, a custom-built operating system from IceWhale that is based on CasaOS—a lightweight, open-source platform designed for simplicity and ease of deployment. ZimaOS retains the core principles of CasaOS but adds refinements tailored to the Zima ecosystem, particularly features that emerged during development of the more powerful ZimaCube. The out-of-the-box experience is beginner-friendly, offering an intuitive web dashboard called “LaunchPad,” which centralizes access to installed applications, system controls, and file management.

ZimaOS is pre-installed on the board’s eMMC storage, enabling immediate setup without requiring users to flash a drive or download additional software. Despite the modest resources of the ZimaBoard 2, the OS performs responsively, even with several services running in parallel. The interface is clean, albeit minimalistic, focusing on usability over deep customization.

For users who are new to home servers or Docker deployments, the learning curve is surprisingly gentle. Though it lacks some of the granularity of more established platforms like OpenMediaVault or TrueNAS, it’s clear that IceWhale has designed ZimaOS to get users up and running quickly without sacrificing key functionality.

One of the more distinctive features of ZimaOS is its integrated App Store, which acts as a curated hub for Docker-based applications. Unlike traditional NAS interfaces that require command-line Docker commands or extensive Portainer configuration, ZimaOS simplifies deployment through one-click installation and automated environment setups.

Popular applications like Plex, Jellyfin, Stable Diffusion, and more are available by default, with the option to add third-party sources for broader container variety. Behind the scenes, the system leverages containerization frameworks to handle resource isolation and volume mappings, but much of this complexity is hidden from the end user.

Application setup is further eased by pre-configured defaults such as port assignments, directory structures, and even PUID/PGID settings, reducing friction for non-technical users. For those with more experience, ZimaOS still allows you to tweak or override these settings manually. Notably, ZimaOS also includes a basic virtualization interface that supports downloading and running lightweight VMs using prebuilt images.

While this feature is better suited to the higher-specced ZimaCube due to memory and cooling constraints, its presence on the ZimaBoard 2 is still a nice touch and shows that the OS is aiming to grow into a more comprehensive platform. Overall, the application and container ecosystem here punches above its weight, especially considering the resource constraints of the board itself.

In terms of storage and file sharing, ZimaOS delivers a capable if somewhat minimal feature set that prioritizes simplicity over enterprise-style depth. Users can create RAID groups—a new feature compared to earlier CasaOS iterations—manage individual drives, and set up file-level sharing using standard protocols like SMB.

The file manager, accessible through the main dashboard, allows for browsing, copying, and sharing content in a familiar web-based interface. Integration with IceWhale’s own client tool enables a peer-to-peer feature called “peerdrop,” which links multiple Zima-based systems or client devices (like phones and laptops) for rapid syncing and data exchange.

This is especially useful for users who want an easy method to upload media, backup devices, or move files between multiple systems on a local network. Remote access can be enabled through a simple relay-based mechanism, which generates shareable links for specific files or folders, complete with read/write controls. While more advanced access control, encryption, or user quotas are not present in this build, the essentials for home or small office use are here and function as expected.

Cloud integration is also available, allowing the addition of third-party storage such as Google Drive or Dropbox for backup or syncing purposes. Though ZimaOS doesn’t try to replace full-fledged NAS operating systems in terms of depth, it successfully delivers the features most users will need, and its lightweight design ensures responsiveness even on modest hardware like the ZimaBoard 2.

Zimaboard 2 Review – Conclusion & Verdict

The ZimaBoard 2 is a competent and thoughtfully assembled single-board server that builds meaningfully on IceWhale’s earlier efforts, especially the original ZimaBoard and the ZimaBlade. Its design clearly targets users who want more flexibility and performance than traditional ARM-based boards can offer, but who also value power efficiency, silence, and a small footprint. The use of an Intel N150 CPU, 8GB of LPDDR5x memory, dual 2.5GbE ports, and a PCIe 3.0 x4 slot makes it viable for a variety of home server roles—from basic NAS and smart home coordination to lightweight container hosting and local media streaming. Features like onboard SATA, USB 3.1, and a DisplayPort connection further add to its utility. However, there are hardware limitations that may affect long-term suitability for advanced deployments. The soldered RAM cannot be upgraded, and the internal eMMC storage, while useful for initial setup, is too slow for OS-level responsiveness in more demanding use cases. Passive cooling, while appreciated for silence, also imposes some thermal limitations depending on the deployment environment.

On the software side, ZimaOS offers a decent out-of-the-box experience that caters to users with minimal technical background. It handles core tasks like application deployment, file sharing, and system monitoring without requiring advanced configuration, and its Docker-based App Store simplifies access to popular tools. For more experienced users, the system supports third-party OS installation, which is likely how many will ultimately use the ZimaBoard 2. Still, as a bundled solution, ZimaOS has matured significantly and now presents itself as a lightweight, capable, and non-intrusive platform for those who prefer to get started immediately. In the broader context of DIY server hardware, ZimaBoard 2 occupies a middle ground: more powerful and modular than Raspberry Pi-class systems, yet more constrained than full x86 mini PCs or enthusiast-grade NAS hardware. For those who understand and accept these trade-offs, and are willing to plan around its limitations, the ZimaBoard 2 offers a reliable and flexible foundation for compact, energy-efficient computing at the edge.

Zettlab D6 AI NAS Prototype Review – A Glimpse at the Future of Local AI NAS?

The Zettlab D6 represents a compelling entry into the increasingly competitive world of AI-integrated network-attached storage. Developed by a relatively new player in the market, Zettlab is attempting to blend traditional NAS functionality with localized artificial intelligence features, positioning its devices as intelligent storage hubs capable of far more than simple file serving or backups. It’s important to emphasize from the outset that the Zettlab D6 — and its siblings in the D4, D6 Ultra, and D8 Ultra series — are still under development, with the company preparing to launch these systems via crowdfunding rather than established retail channels. This distinction is not trivial: what we’re looking at here is a prototype, an early production model meant to demonstrate core functionality, not a finalized consumer-ready product. As such, this review assesses both the current capabilities and the projected potential, while keeping in mind the expected evolutions that may come post-launch.

This review is based on a pre-release prototype of the Zettlab D6, supplied ahead of the official crowdfunding campaign. While the unit demonstrated strong hardware build quality and successfully showcased many of the local AI features promoted by the brand, it’s important to note that this version may not fully reflect the final product that backers will receive. As development continues, both software and functionality are expected to evolve. A follow-up video will be produced closer to the end of the crowdfunding campaign to reassess the system, evaluate any updates, and determine how closely the final release aligns with early expectations.

PROS

Real local AI processing (image recognition, OCR, transcription, semantic search) works without internet access on the D6.
Intuitive natural language commands for system control (e.g., adjust fan speed, create users, reboot) via built-in AI chat. But still very early days...
Excellent LCD display provides real-time system stats (CPU, RAM, IP, disk status) — rare at this price point.
Fast and responsive UI with good UX; even advanced features like RAID setup and AI search feel snappy and polished, if a little feature lite at this development stage
One-click SD card backup with programmable automation tasks (copy, transcode, eject) — ideal for photographers and creators.
Unique design and solid build quality
Fully populated app center, thanks to the community, ready packaged container deployment at 1 click
Clear product segmentation between D6 and Ultra models (better AI support, faster connectivity, PCIe expansion), allowing users to scale as needed - but could be clearer about the need for an included 1-click local AI client model on the client app requirements.

CONS

Not final software — many features are still in beta or marked “coming soon,” including VM hosting and first-party AI enhancements.
Partial dependency on desktop client for advanced AI functions (like document chat and LLM integration) on the D6 model.
Crowdfunding risks — as a pre-release, crowdfunded device, the final user experience may differ from the reviewed prototype.

Zettlab D6 AI NAS – Hardware Design

Positioned as a mid-tier offering in the range, the D6 occupies a unique spot in Zettlab’s portfolio. It’s more powerful than the compact 4-bay D4, but stops short of the considerable hardware resources found in the D6 Ultra and D8 Ultra. At the heart of the D6 lies the Rockchip RK3588, an ARM-based SoC (System on Chip) that features eight processing cores and an integrated NPU (Neural Processing Unit) capable of six trillion operations per second (6 TOPS).

This chip has become a popular choice for AI-at-the-edge applications due to its low power draw, reasonable performance, and growing developer ecosystem. Complementing the CPU is 16GB of LPDDR4x memory — soldered to the board and non-upgradable — which is ample for many NAS workloads but may bottleneck under high AI load or virtualization. Storage-wise, the system includes six SATA drive bays and a single M.2 NVMe slot for SSD caching or high-speed application hosting. The OS resides on a 32GB eMMC module, which, while functional, is slower and less durable than SSD alternatives found in higher-tier models.

By contrast, the Ultra-class models — the D6 Ultra and D8 Ultra — are built around x86 architecture, using Intel’s Core Ultra 5 125H processor. This CPU offers a dramatic leap in compute potential, with 14 cores (combining performance and efficiency cores), 18 threads, and an integrated AI engine capable of 34 TOPS. These devices support up to 96GB of DDR5 memory via SODIMM slots and include dual PCIe Gen 4 M.2 NVMe slots for storage or app caching. So, an important thing that potential buyers of the standard D4 and D4 model need to note is that this system arrives with ‘on board’ memory, not ‘SODIMM’. This is not uncommon on more ‘efficient’ CPU-powered systems, but AI processes can get really memory hungry and that fixed 16GB, although good to have ‘out the gate’ could potentially serve as a low glass ceiling for heavier ops later on.

They also ship with a 256GB SSD for the operating system, eliminating the limitations of eMMC entirely. The D6 Ultra provides six drive bays like its ARM counterpart, while the D8 Ultra expands to eight, catering to users with higher storage demands.

Network interfaces also scale accordingly, with dual 10GbE ports on the Ultra devices, significantly improving throughput for AI workloads or media editing environments. This clear segmentation allows Zettlab to cater to both entry-level users and more demanding professional or prosumer environments.

Although the D6 is not as performance-heavy as the Ultra models, it still delivers a surprisingly mature and distinctive hardware design — especially for a product from a startup brand. Visually, the D6 breaks from the mold of black-box NAS devices with a more industrial design language. The drive trays are notably robust, offering support for both 3.5” and 2.5” drives without the need for tools, and include subtle shock absorption to reduce wear during hot-swaps. Behind the trays, a SATA backplane keeps cabling clean and ensures good airflow, aided by a rear-mounted fan.

The chassis is largely steel and aluminum, with solid build quality across panels and connectors. The front panel features a real-time 3.49-inch LCD display — one of the best I’ve seen in this price range — capable of showing system temperature, CPU and memory utilization, storage status, and network throughput.

This is complemented by an LED lighting strip and a programmable hardware copy button, as well as a comprehensive set of front ports including a USB-C and USB-A port (both USB 3.2 Gen 1), SD3.0 and SD4.0 card readers, and a TF card slot.

Connectivity on the D6’s rear I/O is functional, if modest by today’s standards. It includes one standard Gigabit Ethernet port and one 2.5GbE port — which, while useful for small workgroups or home streaming setups, may limit its viability in higher bandwidth environments.

USB 2.0 ports are also present, mainly for legacy peripherals or UPS/KVM support. There is a single HDMI 2.0 port capable of 4K output at 60Hz, which opens the door for potential direct media playback or GUI access, though its use cases are still undefined in the current firmware.

Notably missing is any PCIe expansion capability — a feature reserved for the Ultra models via their SFF-8654 Gen4 x8 connector. This omission makes sense in the product segmentation strategy, but prospective users who anticipate needing expansion — whether for faster networking, GPU acceleration, or additional storage — will need to look to the higher-tier models.

Still, for what it is, the D6 offers a complete and well-assembled foundation, and the early signs in terms of temperature control, acoustics, and system stability are encouraging.

Zettlab D6 – Software and Services Review

Before we get into exactly what this system can and cannot do, I need to highlight that the D6 prototype I received does not feel like a finished product yet. I have been monitoring this brand and it’s solution for 6 months (even having a different prototype sent to me as fast back as October 2024) and although I have seen ALOT of changes and improvements in the GUI, the software features, storage optimization, performance and consistency – the Zettlab OS does not feel finished yet.

The hardware feels robust and ready to go! But the software still feels like development is ongoing. This makes a lot of sense in the context of crowdfunding a product and I can appreciate that the brand needs real world feedback and development time. However, that does mean that reviewing the software is tough! As I have to balance what the system does TODAY against what the brand says it will be able to do TOMORROW. So keep that in mind as you read this software review.

One of the standout ambitions behind the Zettlab D6 is its integration of localized artificial intelligence. While most consumer NAS systems limit themselves to media management and basic data organization, Zettlab’s vision goes much further: a platform that applies real-time AI processing to images, audio, video, and documents — all without relying on cloud services.

This pitch is especially appealing in a world where data privacy is an increasing concern. In practice, the D6 delivers some truly novel capabilities, although it’s important to remember this software is still in active development. Not all features are complete, and the performance and behavior of certain AI tools are still subject to change.

The D6 runs on ZettOS, a proprietary operating system built around containerized apps, lightweight AI inference engines, and standard NAS functions.

ZettOS resembles a more refined version of a web-based Linux desktop, complete with user management, storage setup, application deployment, network configuration, and protocol support (SMB, FTP, WebDAV, etc.).

While the core system functions well, it’s the AI layer where things begin to differentiate the D6. ZettOS offers native support for facial recognition, object detection, OCR, and natural language search — all running directly on the device.

Image tagging, semantic queries like “men standing near trees,” and auto-transcription of audio and video files are examples of what’s already functional today.

One of the more impressive capabilities is real-time media classification. Photos added to the NAS — whether uploaded manually, copied via SD card, or moved over the network — are immediately scanned and indexed. Users can search for visual content by descriptive terms rather than filenames. For example, searching for “cats,” “dice,” or “flowers” surfaces content accurately, regardless of how files were named.

This indexing happens locally and often within seconds of upload, leveraging the RK3588’s integrated NPU. Similarly, when audio or video files are uploaded to designated folders, the system automatically transcribes them using onboard tools. The Clip application handles this, and within moments, transcripts appear with speaker identification and time-linked navigation.

The AI features are tied to a broader system of prompts and shortcuts. A dedicated “AI Chat” interface allows users to type commands like “increase fan speed,” “reboot the system,” or “create a new user.” Many of these commands work today and are executed promptly, showing promise for a more natural interface between user and NAS.

While it’s far from full AI orchestration, the groundwork is clearly there. The system also supports basic automation — for example, auto-import tasks triggered when an SD card is inserted can move, rename, or transcode files and even safely eject the card afterward. These are practical, time-saving tools that go beyond novelty.

ZettOS includes a growing App Center with one-click deployments of popular open-source tools like Jellyfin, Nextcloud, Image, and Home Assistant. Apps are containerized and installed quickly, with port forwarding handled automatically. While this is becoming common among modern NAS platforms, ZettOS executes it cleanly and without needing user intervention.

Some proprietary applications, such as Creator Studio and virtual machine hosting, are marked “coming soon” in the current builds, with roadmap estimates targeting mid-2025. It’s clear that while ZettOS is already usable, it is also a work in progress.

Notably, the AI document analysis and generative chat features currently require the desktop companion app for full functionality on the D6 model, with a locally downloaded AI model (1 click from the client software install, but still, this could be clearer in the online documentation!).

While the basic indexing and media analysis are handled on-device, more advanced interactions such as querying large document sets or generating context-specific answers appear to rely on the Windows or Mac client.

This distinction is critical: the more powerful Ultra models promise full offline AI, while the standard D6 offloads some computation. Transparency about how much AI is truly local versus partially remote will be key for user trust going forward.

Zettlab D6 Prototype Review – Conclusion and Verdict

Overall, the Zettlab D6 offers one of the most advanced AI software stacks seen in a consumer NAS at this level — even in its unfinished state. With real-time image recognition, semantic search, speech-to-text transcription, natural language controls, and media classification, it exceeds what many larger NAS brands have offered to date. There are still rough edges, missing features, and questions about long-term support, but what’s already functional is impressive. For early adopters and tinkerers, this is a promising glimpse of what local AI NAS could become. For others, it may be worth waiting to see how ZettOS matures over the next development cycle.

Important – This review is based on a pre-release prototype of the Zettlab D6, supplied ahead of the official crowdfunding campaign. While the unit demonstrated strong hardware build quality and successfully showcased many of the local AI features promoted by the brand, it’s important to note that this version may not fully reflect the final product that backers will receive. As development continues, both software and functionality are expected to evolve. A follow-up video will be produced closer to the end of the crowdfunding campaign to reassess the system, evaluate any updates, and determine how closely the final release aligns with early expectations.

J’sais pas vous, mais moi ici, j’ai plein de vieux smartphones toujours en état de marche qui dorment dans les tiroirs. Des OnePlus, des Xiaomi, des Samsung… Des monstres avec 8 cœurs, 6 Go de RAM et 128 Go de stockage qui battent à plate couture mon Raspberry Pi, mais qui pourrissent lentement à cause d’un Android devenu obsolète. Parfois je les donne, parfois je bidouille un peu dessus mais concrètement, je n’en fais pas grand-chose.
