As of mid-2025, the sub-$499 NAS market is more competitive than ever, with several brands offering systems that deliver strong hardware, dedicated operating systems, and multiple drive bays within a modest budget. For home users, prosumers, and small teams looking to centralize data, manage backups, or stream media locally, this price bracket now includes options that would have cost significantly more just a few years ago. From rackmount storage appliances to compact flash-based servers, there are now choices to suit a wide variety of workloads and network environments.

This article examines five out-of-the-box NAS systems that are currently available for $499 or less. While each system takes a slightly different approach—whether prioritizing raw bandwidth, containerization, virtualization support, or software simplicity—they all represent viable solutions for users seeking value without compromising core functionality.

Important Disclaimer and Notes Before You Buy

All of the NAS systems featured in this list are diskless, meaning they do not include storage media by default. Users will need to purchase compatible 3.5″ HDDs, 2.5″ SSDs, or M.2 NVMe drives separately depending on the system’s configuration. This significantly affects the total cost of ownership, particularly for all-flash systems where NVMe drives are required. Some devices also use onboard flash or eMMC storage to house the operating system, but this is not sufficient for general file storage. Buyers should also consider the cost of drives, RAID redundancy planning, and any accessories (e.g., cables or cooling enhancements) when budgeting for deployment.

Another consideration is the variation in NAS operating systems provided. While most models come with a vendor-specific OS—such as Synology DSM, TerraMaster TOS, UGOS, or Unraid—some platforms allow or even encourage the installation of third-party alternatives like TrueNAS or Unraid without voiding hardware warranties. However, in cases where the software stack is less mature or limited in features, users may need to invest more time configuring services such as Plex, Docker, or SMB sharing manually. As such, these systems are best suited to users who are comfortable managing basic network services or are willing to explore more advanced functionality over time.

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.

Synology Beestation Plus 8TB Revealed and Detailed

Synology has unveiled the BeeStation Plus (BST170-8T) in their pre-Computex build up (alongside an early reveal back in Jan 2025 at CES/Pepcom), the latest addition to its growing portfolio of personal cloud storage solutions aimed at everyday users. Building on the success of the original BeeStation (BST150-4T), the Plus model directly addresses feedback from users who wanted greater capacity, faster performance, and more versatile applications—without the steep learning curve of traditional NAS systems. This one-bay device ships pre-populated with an 8TB Synology HAT3310 hard drive (7200 RPM), powered by a quad-core Intel Celeron J4125 processor and 4GB of non-upgradable DDR4 memory. The combination is notable because it brings x86-class processing and hardware transcoding support to an ultra-simplified setup—something virtually unheard of in this form factor. With its out-of-the-box readiness, cloud-linked setup process, and focus on seamless user experience, BeeStation Plus is designed for those seeking to move away from Google Drive, iCloud, and Dropbox subscriptions, offering complete local control of data without compromising on usability. Features such as AI-driven photo management, native mobile apps, and Plex Media Server support are now included, making this device far more than just cold storage. For individuals and families looking to centralize their backups, photos, videos, and personal files in a user-friendly ecosystem—without paying monthly cloud fees—Synology positions the BeeStation Plus as an appealing middle ground between cloud services and more complex NAS platforms like the DiskStation DS224+.

Synology Beestation Plus 8TB – Who Is This For?

The BeeStation Plus is designed with a clear goal: to serve individuals, families, and small teams who want private, centralized storage without the barriers that typically come with managing a traditional NAS. It’s aimed at users who are familiar with cloud platforms like Google Drive, Dropbox, or iCloud, but want to move away from recurring subscription fees and the privacy concerns associated with third-party cloud storage. For many, the idea of hosting data locally remains appealing—yet the complexity of DSM-based Synology systems can be overwhelming. The BeeStation Plus sidesteps that entirely by offering a plug-and-play experience: no drive installation, no volume configuration, no knowledge of RAID, and no need to navigate DSM’s enterprise-leaning control panels.

Instead of DSM, BeeStation Plus runs a simplified, task-oriented operating system that emphasizes automation and immediacy. Setup is handled via a QR code and cloud-linked sign-in process using your existing Apple or Google account. Within minutes, users can begin backing up photos, syncing cloud drives, or transferring personal data using intuitive applications like BeePhotos and BeeFiles. Notably, BeePhotos offers local AI processing for face recognition and subject categorization—no data is sent to the cloud, and everything runs on-device using the integrated GPU in the Intel Celeron chip. These features mimic what users expect from modern photo cloud services, but with full local ownership.

Where the DiskStation platform caters to power users—with capabilities like multi-tiered storage pools, user-group policies, virtualization, Docker containers, and dual-LAN failover—BeeStation Plus avoids this complexity altogether. While some may view it as limiting, Synology has correctly identified a growing segment of mainstream users who simply want a secure, reliable, and easy-to-manage storage hub for their files, memories, and work. For them, BeeStation Plus delivers a near turn-key solution that doesn’t demand IT knowledge or ongoing configuration, while still offering meaningful tools like Plex integration, two-way cloud sync, and internal snapshot recovery.

Synology Beestation Plus 8TB – Hardware Specifications

At the heart of the Synology BeeStation Plus is the Intel Celeron J4125, a quad-core x86 processor that, while not cutting-edge, is a substantial leap from the Realtek RTD1619B used in the original BeeStation. The J4125 brings integrated Intel UHD Graphics 600, enabling hardware video transcoding—critical for smooth 4K Plex streaming and responsive AI-powered photo recognition within BeePhotos. This CPU choice also allows Synology to run a broader range of services, including native Plex Media Server installation and enhanced indexing performance for large photo or document libraries. Paired with 4GB of DDR4 memory, the system is built to handle simultaneous user access and background tasks like backups and media processing without performance degradation—something the original model struggled with due to its lower RAM and ARM-based chip.

The BeeStation Plus ships with a pre-installed 8TB Synology HAT3310 hard drive, a 7200 RPM SATA HDD from Synology’s own verified drive lineup. While the device only supports a single internal bay, the included drive offers ample performance for most home and SOHO workloads, and the use of a higher-RPM disk ensures better responsiveness for large file transfers and indexing tasks. The storage is non-removable by design, as BeeStation products prioritize simplicity and stability over modularity. This also means there is no RAID support—underscoring that this device is not built for redundancy, but rather for centralized storage with optional external or cloud-based backup using BeeProtect or a secondary Synology NAS.

Connectivity is modest but practical. The system includes one 1GbE RJ-45 Ethernet port for network access and two USB 3.2 Gen 1 ports (one Type-A and one Type-C) for expanding storage or performing external backups. External drives can be browsed directly via BeeFiles or automatically backed up using the system’s USB Backup function. While some users may lament the lack of 2.5GbE or additional LAN ports, it’s worth noting that the target audience likely won’t saturate even gigabit speeds in everyday use. In real-world tests, BeeStation Plus can hit 150–180MB/s read speeds from its internal drive—enough to support simultaneous multimedia streaming and active file transfers across the network. The compact chassis also includes a cooling fan, a new addition over the passive original BeeStation, helping ensure thermal stability during extended workloads like Plex streaming or bulk photo indexing.

Synology Beestation Plus 8TB – BSM Software and Services

The BeeStation Plus is tightly integrated with Synology’s Bee-branded suite of applications, which form the foundation of its user experience. Chief among them is BeePhotos, a powerful photo management tool that automatically backs up images from mobile devices and organizes them using on-device AI for face, subject, and location recognition. Unlike cloud photo services, all indexing occurs locally, ensuring that sensitive images never leave the device. BeePhotos now supports iCloud Photo Backup, enabling direct migration of Apple photo libraries without requiring intermediate steps via your phone or computer. The web interface replicates the timeline-based design familiar to users of Google Photos or iCloud, complete with album views, smart filters, and Chromecast streaming. Meanwhile, BeeFiles acts as the central file manager, supporting version history, password-protected sharing, USB device browsing, and desktop sync via the BeeStation desktop client for Windows and macOS.

Beyond personal use, Synology has also included multi-user support for up to eight invited users, each with isolated private storage spaces and individual access rights. Users can connect to BeeStation from anywhere via the Synology cloud portal or mobile apps, allowing seamless collaboration and remote file access. BeeStation Plus also introduces native support for Plex Media Server, offering hardware-accelerated streaming of 4K content to TVs, tablets, or mobile devices. Integration is simplified through the BeeStation web portal, and libraries can be organized via BeeFiles’ dedicated “Plex Media Library” folder structure. Users can also take advantage of BeeProtect, a low-cost, unlimited-capacity cloud backup service that stores a full copy of the BeeStation’s data offsite—ideal for disaster recovery. Internal snapshot-based restore points add another layer of protection, allowing users to roll back the system in the event of accidental deletions or ransomware events, without relying on third-party services.

Synology Beestation Plus vs Synology DS224+/DS225+ and Beestation

The BeeStation Plus represents a clear technical upgrade over the original BeeStation, featuring a move from an ARM-based Realtek RTD1619B processor to a quad-core Intel Celeron J4125, along with a jump from 1GB to 4GB of DDR4 RAM. It also swaps the 5400 RPM 4TB HAT3300 drive for a faster 7200 RPM 8TB HAT3310, doubling the storage and improving responsiveness for tasks like AI photo indexing and multimedia playback. The inclusion of an active cooling fan further reinforces its suitability for continuous workloads, while added support for Plex Media Server and iCloud Photo Backup expands its capabilities far beyond the entry-level functionality of its predecessor. Both units share the same compact 1-bay form factor and cloud-integrated setup process, but the Plus model is built for heavier use, particularly in multi-user homes or for users archiving large libraries of photos and videos.

Synology Beestation Plus 8TB – Pricing and Release

The Synology BeeStation Plus (BST170-8T) launched globally in May 2025 with a suggested retail price of $369.95 USD (excluding VAT), positioning it as a compelling middle-ground between basic cloud drives and full NAS systems. This price includes the pre-installed 8TB Synology HAT3310 hard drive, three months of complimentary BeeProtect cloud backup, and full access to the BeeFiles and BeePhotos applications out of the box. While significantly more expensive than the original BeeStation’s $199.95 launch price, the BeeStation Plus delivers a considerable leap in performance, storage, and application support. Synology is clearly aiming to attract users looking to escape rising cloud subscription fees, with the device’s total cost of ownership undercutting comparable iCloud or Google One plans over just a few years. With increasing emphasis on private cloud solutions that are easy to deploy, the BeeStation Plus marks Synology’s most consumer-friendly push yet into the mainstream storage market.

How to Install TrueNAS Scale/Core on a Terramaster NAS

If you’re new to private server storage, you’ve probably heard the phrase “everything runs on Linux.” While that’s not entirely true (many other platforms exist with their own foundations), Linux remains the dominant base for much of the software we use daily—including Network Attached Storage (NAS). When it comes to NAS, most new or less experienced users fall into two main categories:

1. DIY Enthusiasts – Those who prefer to build their own systems, optimizing costs and flexibility with open-source platforms like TrueNAS Scale (the Linux-based counterpart to the popular TrueNAS Core on FreeBSD).
2. Turnkey Buyers – Those willing to pay extra for a prebuilt system, even if it means dealing with some software limitations.

But what if you want the best of both worlds? Good news—you can have it! In this guide, I’ll show you how to transform TerraMaster’s highly affordable NAS solutions (arguably the best value on the market right now) into a TrueNAS -powered, ZFS-backed NAS system. Even the 2024/2025 models come well-equipped with multiple NVMe support (the F8 SSD PLUS as a particular stand out device), 2.5GbE networking, embedded graphics CPUs, and more, making them a fantastic base for a Linux NAS.

Best of all, setting this up is much easier than you might think, completely reversible, and provides you with the customization and flexibility of TrueNAS while still benefiting from a prebuilt 24/7 server at an unbeatable price. Sounds great, right? Let’s get started with the step-by-step guide!

Note – You can watch my FULL 30 Min+ beginners Guide to installing TrueNAS on a Terramaster NAS Here

TrueNAS on Terramaster – What You Need?

Before you begin, it’s important to note that simply owning a TerraMaster NAS isn’t enough. To get TrueNAS up and running, you’ll need to complete a few preliminary checks and have a few extra items—many of which you may already have at home or in the office. If not, a quick $10 purchase online should cover it.

To upgrade your TerraMaster NAS to TrueNAS , make sure you have the following:

• A Terramaster NAS Drive with (minimum) an Intel 64bit x86 CPU and a minimum 2GB of Memory (recommended 8GB+)
• Download the latest stable release of TrueNAS here as a system image (you will be converting this to USB later on) – DOWNLOAD
• Any Data that is currently on the Terramaster NAS RAID that is mission critical to be backed up or moved (as it will be completely formatted)
• A USB drive no bigger than 9mm x 17mm x 20mm ( I STRONGLY recommend THIS ONE here from Sandisk, as it is low price and incredibly small, even at 32GB)

 

• I recommend not using a USB larger than 32GB, due to the constraints of 1st party software to format larger than this in FAT32. Don’t be tempted to spend like $2 more for a 64GB, as the TrueNAS installation will occupy the full USB space (as you will create a system-image-USB) and space is utterly irrelevant when the TrueNAS installation is so small
• A Disk Image to USB conversion too. I recommend ‘Rufus’, currently in ver 3.19 and can be run in a portable .exe form that doesn’t require installation – DOWNLOAD
• A basic USB Keyboard (example HERE but really, any will do) and an HDMI Monitor (or simply any device that has an HDMI input – NOT output) such as a TV or Capture card
• Hard Drive and/or SSD media (you should already have these, but just in case) for your storage
• Optional – Download Advanced IP Scanner HERE, as it is a really useful tool for analyzing your network and finding your new TrueNAS NAS for remote access

That is about it. Most of these (maybe not the USB drive at that physical size) you will almost certainly already have to hand.

Can I Reverse the TrueNAS Installation back to Terramaster TOS?

Almost certainly, yes! However, there is one key consideration. When switching from TerraMaster’s TOS to TrueNAS , the internal drives (HDDs and/or SSDs) will be formatted to ZFS, meaning they won’t be recognized by TOS if you choose to switch back later.

The good news? Reverting back is incredibly easy—all you need to do is replace the internal USB drive and reboot the system. However, switching between NAS operating systems will wipe the data on the drives, so be sure to back up your important files elsewhere before proceeding.

Now that you’re ready, let’s move on to installing TrueNAS on your TerraMaster NAS!

TrueNAS on a Terramaster NAS – Step 1, Download TrueNAS

Head to the TrueNAS website HERE and download the latest stable release of the software to your local PC, Linux or Mac system. Make sure to remember where you downloaded it.

TrueNAS on a Terramaster NAS – Step 2, Download Rufus USB Image Tool

Head to the Rufus website and download the latest version of that tool – I recommend downloading the standalone executable file here, as then it will immediately run when you double click the file, without installation etc. It may redirect you to Github, but it will be the same executable file. Once again, remember where you downloaded it.

TrueNAS on a Terramaster NAS – Step 3, Preparing the USB

Connect the small form factor USB Drive to your system (again, this is the one I used from Sandisk) and after a few seconds, it should appear as an available USB Drive. The drive MAY need formatting (you will be prompted to do so), if that is the case, then you can format it via the system prompts and by default, it will format it to FAT32 (as long as your USB is less than 32GB). If you are not presented with a system prompt to format your USB, then you can head into My PC, or My Computer via a windows computer and right-click the drive, select ‘format’ and format it that way.

If you have used the USB for other things previously, there is a chance that the drive has existing partitions in place. For that, the quickest way to completely remove any partitions is to open up the bottom-left windows system menu as normal, and then just type diskpart and open the command-line GUI tool. From there, use the command list disk to show the available drives that are connected, you will see your USB (normally disk 1 or 2, but can differ depending on your system layout and can be spotted by the storage amount). From there, type select disk # (where # is the drive number that your USB is shown as) and then type clean, which which will then remove any index structure for the drive (i.e the partitions and existing format) and then you can go back to the My Computer/My PC page and format the drive to FAT 32 as normal.

TrueNAS on a Terramaster NAS – Step 4, Creating a USB Installer Image of TrueNAS

Open the Rufus application and from there you will see the USB Drive (listed as NO NAME, or ‘UNTITLED’, ETC) at the top. From there, look to the select image/find image option (depending on the ver. of Rufus or your USB Image Creator tool of choice) and find the TrueNAS disk image you downloaded earlier). If the drive is not listed, it may have downloaded as a compressed/archive file. If that is the case, head to the location of where you downloaded TrueNAS (in your file explorer, not in Rufus) and right-click the file you downloaded. If the option to ‘extract‘ is visible, then you can extract it (i.e unpack it to the original form) in that same download directory. From there, head back into RUFUS and then the TrueNAS system image should be visible. Select it, then run the Rufus System image creator tool and create your USB bootable TrueNAS disk image.

REMEMBER! This will completely format your USB drive and any files that are on that USB will be destroyed. The system image creator tool will turn the USB into a pure boot image tool – the USB will not be usable for traditional storage again unless you completely format it again.

TrueNAS on a Terramaster NAS – Step 5, REMOVE THE USB FROM YOUR PC!!!!!!!!!

Really, really important and sometimes overlooked. Once the USB creation is completed, you need to remove the USB (using the eject hardware safely option at the bottom right of your windows machine taskbar as normal). DO NOT accidentally leave the USB in your USB Ports for any longer than necessary. If you leave it in and your system reboots at any point (eg in a normal ‘end of day shut down, go home, reboot tomorrow’ scenario), then the system might boot directly into the TrueNAS installation and although it is easy to exit from, it can change your system default boot preferences, maybe even remove your primary boot drive as the OS drive – requiring a little messing with a windows installation disk to change it back. The odds of this are very small, but not zero, so make sure to safely remove your USB drive when the TrueNAS system image creator tool is completed.

TrueNAS on a Terramaster NAS – Step 6, Opening up your Terramaster NAS

This next step is going to differ depending on the Terramaster NAS Drive you are choosing to use. For this guide, I am using a 2022/2023 generation F4-423 4-Bay NAS, but the general steps are the same for any Terramaster NAS (though the location of the USB will differ) (the F8 SSD PLUS for example has a particularly secluded USB key internally). With the Terramaster NAS disconnected from the network and from any power source. From there you will need to remove the external casing. In the case of most Terramaster NAS, the chassis is held by 4-6 screws on the rear of the casing that, when removed, allow you to remove the rear pannel+fans and slide the internal framework out the front of the casing (be sure to check the fans are not disconnected accidentally in this process). IMPORTANT – Remove any HDD/SSD Media during the dismantling of the Terramaster NAS chassis, as it would be so, SO easy to harm these with accidentally dropping/motion damage. No need to remember the order of the drives when you re-install them, as they are going to be formatted during the TrueNAS installation.

Now, if you take a closer look at the main controller board of the Terramaster NAS (the one with network/USB ports attached, not the one that the HDD/SSD bays are on), you will spot a VERY small USB module in a tiny USB port. It should look something like this:

Now, THIS is where the default Terramaster TOS NAS software installation is kept. This is NOT where the OS actually runs from, but this is where the system checks in it’s BIOS when booting to find installation media (IF the system does not already have an active OS on the drives). Very delicately (as it IS a small USB and likely tucked in next to some other delicate components) remove the USB there is there, put it somewhere safe (as you will need this if you ever want to return the Terramster back to a TOS software system) and then replace it with the USB from earlier that has the TrueNAS system image you created in Rufus. THIS is why you needed a very small USB, as otherwise there is simply no way you would fit a traditional USB flash stick in the space provided.

That is pretty much it. This only other thing to factor in here is IF your Terramaster NAS does NOT have an external HDMI port. Most Terramsater NAS released in 2020-2025 have an HDMI port on the rear that although largely useless in TOS, is still accessible (something you will need for TrueNAS initialization. However, some Terramaster NAS with Intel Processors have the HDMI Port located INSIDE the main chassis (especially the older great box 2019-2020 gen devices). So, IF your NAS has an inside HDMI port, you are going to need to connect an  HDMI monitor to it and run the initial installation (covering in a bit) with the chassis in this open state. After installation is complete, you can close the Terramaster NAS chassis up. Otherwise, if your NAS already has an external HDMI port, you can go ahead and reconstruct the NAS chassis. Essentially, if you NAS has integrated graphics (Intel Celeron, Pentium, N100, N305, Core, etc), you will have an HDMI output.

NOTE – If you plan on upgrading the memory of your NAS to 8GB-16GB (in order to use ALL of the features of TrueNAS to their fullest extent), I would recommend doing so at this point before rebuilding the physical chassis again, as many Terramaser NAS have the 2nd SODIMM memory slot in really tight locations.

TrueNAS on a Terramaster NAS – Step 7, Accessing the HDMI Port and Keyboard Control

Next, you need to start getting the system ready for Initialization and Setup. I would strongly recommend running the first-time installation via a direct interface with the Terramaster NAS. You will need to connect an HDMI Monitor/TV/Capture Card to the HDMI port of the NAS, a Keyboard (and/or mouse) to an available USB port) and then connect the power/network connections to the NAS and boot the device up.

After a few minutes, the TrueNAS GUI/Command will appear on your monitor and all you need to do is navigate the config choices to set up your TrueNAS NAS the first time.

Important – TrueNAS Scale/Core runs at its best when it is run on a separate drive from your storage. Much like an Operating System, you can install TrueNAS on an available SSD in a SATA or NVMe SSD slot in the Terramaster NAS, then (after initialization) you can go into the TrueNAS > Storage area and create a pool of storage using the available storage media bays,

It is NOT recommended that you install it on a USB drive, for reasons of speed and power-connections.

After you have completed the setup and are back at the initial TrueNAS boot menu, select the ‘SHUTDOWN‘ option (not reboot/restart, for reasons I will explain in a moment).

TrueNAS on a Terramaster NAS – Step 8, Remove the Boot USB Drive

Once your Terramaster NAS has fully powered down, you need to disconnect the storage, power and any other cables, then open up the Terramaster NAS again (if it was re-constructed from earlier) and then remove the USB drive you installed earlier with TrueNAS boot loader on it. You need to do this as otherwise, when you reboot the Terramaster NAS, it will reboot into the bootloader again. You can skip past this and/or it will not action a reinitialization without your input, but better to remove the USB and therefore allow the system to always immediately boot into the TrueNAS system. After you have reconstructed the terramaster NAS, you can go ahead and connect all the cables and power on the device.

Note – Do NOT replace the USB with the original Terramaster USB Drive that it arrived with, or the system will auto boot into the Terramaster TOS Installation setup.

TrueNAS on a Terramaster NAS – Step 9, Reboot the NAS

Upon rebooting the Terramaster into TrueNAS (can take up to 5 mins, but usually much quicker). You have two options with how to access the configuration and controls. You can use the HDMI+Keyboard if you choose for console/command level access, but it will be ALOT higher a learning curve than the network GUI.

Alternatively (much more recommended), use a program such as Advanced IP Scanner, which is free and VERY useful anyway, or even network command prompt) to scan your local area network and find where the Terramaster with TrueNAS is located (i.e it’s IP). This IP (eg 192.168.1.111) is what you put into the URL bar ofay web browser and it will load into the login GUI for TrueNAS . From here you will need to use the username ‘root’ in combination with the password that you created during initialization.

And that is about it. You now have TrueNAS installed as the default OS of your Terramaster NAS. From here you can do anything and everything that his highly regarded ZFS powered server software offers. Head into the Storage area and start creating pools, as well as areas for caching and lots more features.

TrueNAS Core was recently updated to ver.13 in a stable release of the FreeBSD format, as well as new improvements in the Linux-based version ‘TrueNAS ‘. The first thing you are going to need to do when setting up your TrueNAS > Terramaster NAS server is set up your storage. Do this by heading into the storage tab and following the handy steps on screen. After that, you can pretty much do anything on your new ZFS NAS!
