UGREEN NASync Celebrates 2 Years – But Is UGREEN Ready for the Big Leagues?

Two years ago, the popular battery and PC accessory company UGREEN, launched their Kickstarter campaign for the NASync personal NAS series of devices. The brand already had a steadily growing foothold in China with their DX series of NAS devices, but were still a huge outsider in the world of NAS globally. Fast forward two years, a $6 Million crowdfunding campaign, 6 new NAS releases, a new NAS kickstarter in progress (the IDX6011 AI NAS) and generally undermining long-time players who have been in the NAS market for more than a decade – UGREEN is looking like quite a beast in the world of NAS! But two years, UGREEN now finds that along with an increased market position also comes increased demand, scrutiny and expectation. I went to Shenzhen, China, to speak directly with the teams who direct and create their NASync division to ask them them questions about the development of this series, lessons that were learnt, where they are going and what they still need to do to further establish their position in the turnkey NAS market.

Full Disclosure – this Q&A has NOT been sponsored, subsidised or creatively controlled by UGREEN. These questions are my own, submitted to UGREEN 48 hours prior to the interview, and the answers provided were directly from their team.

UGREEN was already a well-established company in its own right before it expanded into NAS systems. So, currently, what is the scale of the teams and resources that your company has allocated to this? R&D, Design, Development, Technical Support, etc?

UGREEN put together its NAS team back in 2018, released its first NAS product in China in 2021, and went global for the first time in 2024, bringing its NAS products to markets around the world. NAS is one of the company’s key strategic product lines, with a team of several hundred people working on it—including product, R&D, design, testing, security, and more. This doesn’t count shared support teams like industrial design, legal, or finance; we’re only talking about people directly focused on NAS. In this whole building, every floor is filled with NAS team members—except for the third floor, which is just the cafeteria.

What has been the biggest challenge in the continued development of your NASync/UGOS services in these last 2 years?

One challenge is resource allocation. We need to support international users at the same time, which means balancing different priorities and expectations. Another challenge is localization. It’s not just about language, but also understanding different user behaviors and usage scenarios. So we had to spend a lot more time to research and validate what users actually need in each region. Based on that, we’ve been continuously adjusting our product direction and improving UGOS to better fit a global audience. It’s definitely an ongoing process, but it’s helped us build a much clearer understanding of the market.

Two years on from your initial crowdfunding, your position in the ‘turnkey NAS market’ from comparative obscurity has catapulted to effectively being in the top 5 (if not top 3) – What do you think UGREEN have brought to the market (or change in the market as a whole) that caused this?

There are a few key things behind that.

Hardware DNA, Built for AI

UGREEN is a hardware company at heart. With our NAS products, we insist on solid hardware—high-performance CPUs, ample memory, high-performance CPUs and ample memory—not just for reliability, but for computing power. AI NAS demands serious performance. Without a strong hardware foundation, AI is nothing more than a concept. Our hardware is designed to make AI run stable and fast.

User-Centric, Not Just a Slogan

We’ve always put ourselves in our users’ shoes. We listen to every voice—on social media, in forums, through user interviews. Many of our features, like snapshots and SAN Manager, came directly from users telling us, “I need this.” Our products aren’t built in a vacuum; they’re shaped together with you.

R&D Investment, Bringing NAS to Everyone

We established our software R&D team, including an AI pre-research team, early on. User feedback has driven us to keep investing, with one goal in mind: to shorten the learning curve. NAS shouldn’t be just a toy for tech enthusiasts. We believe the future of NAS is for everyone—simple, smart, and accessible. This is the path we’re on, and it’s one we want to walk together with you.

The UGREEN IDX6011 AI NAS series has been in development for a long time, and will be headed to its own crowdfunding campaign shortly. What was the biggest challenge you faced in its development and/or lesson that you learned about this new profile of solution?

The biggest challenge was finding the right balance between AI capabilities and real user value. It’s relatively easy to add AI features from a technical perspective, but making them actually useful, stable, and well-integrated into everyday workflows is much harder. Especially on a NAS, NAS is essentially a local storage product, everything runs locally, so for us, it was important that AI features also run locally. But hardware resources and compute power are limited. So the question is, how do we build useful and stable AI features without affecting NAS core functionality like storage, backup and overall system performance? That’s very difficult.

And from product design perspective，it’s also challenging to define the right AI use cases. It’s not about adding more AI features, but making sure they are scenario-driven and actually solve real problems, like better file organization, smarter search, easier intraction… We need to keep the experience simple. Many users are still new to AI on a NAS, so we wanna make things natural and do not add extra complexity. So right now, we’re still in the process of refining and validating these ideas, and making sure we deliver something that’s both practical and reliable for users.

I think it would be fair to say that UGREEN has chiefly focused on Desktop NAS server ownership in their portfolio of solutions to date. But have you explored rackmount solutions, and/or is this something that could happen in the near future?

Actually we’ve done some internal research on rackmount solutions, it’s quite different from desktop NAS in terms of target audience, hardware, software and sales. So it’s not just an extension of what we’re doing now, it requires a different product strategy. For now, our focus is still on improving and expanding our desktop NAS lineup, in the short term, we don’t have a concrete plan for rackmount products, but it’s something we’ll continue to evaluate over time.

Now that UGREEN is a largely established player in the turnkey NAS market, there is a lot more scrutiny on the extent to which your brand preemptively prepares against cyber security threats. What is UGREEN doing to address (in terms of foundations on this platform and broader services) this to avoid a potential slow moving snowballing security incident?

Security is something we take very seriously. At the product level, we provide a range of built-in security features. For example, users can enable DoS protection to defend against network attacks, automatically block IP addresses after multiple failed login attempts, and set up firewall rules to control access from specific IP addresses and built-in Security app to scan for suspicious files We also have a dedicated internal security team and a well-established vulnerability handling process, so critical issues can be identified and resolved quickly. We also provide a vulnerability reporting channel on our official website. If users discover any potential security issues, they can report them to us, and we will assess and respond accordingly.

(Below is a snippet of the Security Disclosure page from UGREEN, available HERE)

At CES 2026, UGREEN unveiled its surveillance platform and edge AI cameras. At that time, your team was kind enough to allow me to see the early development of your NAS surveillance application that will allow full management, direct control and storage of these new Surveillance services. Is development still continuing on this and will this be a service that existing NASync owners will have access to in the future

Yes, development is still ongoing. The surveillance platform you saw at CES is actually a part we are exploring, and is still under active development. From what I understand, AIOT is a broad ecosystem that is going to feature ai NAS, ai-based home security cameras, and many more AI-empowered hardware devices for a smarter lifestyle. On the NAS side, we’re also building our own surveillance application for NASync. We plan to launch it within this year. In terms of compatibility, we aim to support both UGREEN cameras and third-party cameras, so users have more flexibility to build their setup. So overall, both sides are moving forward, but they are different products within the UGREEN ecosystem.

In the last year, UGREEN released two ARM RK chip-powered NAS solutions in the DH2300 and DH4300 – How easy/hard was scaling UGOS onto this more modest hardware base, and were there any useful lessons learned that have benefited your NAS development as a whole?

DH series is our entry-level lineup, designed mainly for NAS beginners and users with simpler needs. From a technical perspective, running UGOS on an ARM-based platform is definitely more constrained compared to x86, especially in terms of performance and resource availability. A lot of things can’t just be directly carried over, we need to re-adapt them for the ARM architecture, including the kernel, system services, and many core features. So we had to be more selective and thoughtful about which features to include and how to optimize them. And from a product perspective, it actually helped us become more focused. With the DXP series, we already emphasized user-friendliness, but with the DH series, we really wanted to take that further and make it as simple as possible, essentially positioning it as a user’s first NAS.

So in practice, we streamlined certain features based on the hardware and target users. For example, we simplified or did not include things like virtual machines and some AI capabilities, and instead focused on delivering a smooth and reliable core experience. One key lesson we learned is that not every product needs to do everything. It’s more important to match the right experience to the right user group. And that thinking has also helped us better define our overall NAS product lineup.

I canvased a large group of UGREEN NAS users (many of whom were part of your original Kickstarter campaign) who are still using their NASync systems to this day, and have followed you on your journey so far. I asked them which features or improvements they would like to see in future updates and revisions to UGOS. Are you able to share if these are features that are on the roadmap, or have been explored?

• Full Volume Encryption
• WORM support
• A mixed drive RAID storage system (comparable to Synology Hybrid RAID or Terramaster TRAID)
• A tiered storage system (unlike the copy system of ‘caching’, but a SSD+HDD composite pool that intelligently moves ‘hot’, ‘warm’ and ‘cold’ data to appropriate storage areas)
• ZFS as a file system choice
• A native Plex Media Server Application
• A local client application for Mac/Windows for file pinning, streaming, intelligent 30-day deletion (see Synology Drive, QNAP Qsync, etc)
• A more comprehensive security scanner (eg scanning for unsecure open ports, SSH being open, weak passwords, admin accounts, auto blocks disabled, etc)

 

We’ve actually seen many of these requests from our users as well, these are very valuable suggestions and we’ve already had internal discussions around most of them. But many of these features, like full volume encryption, hybrid RAID, or tiered storage are quite complex, they take time to design, develop and validate, especially we wanted to make them stable and reliable.

So at this stage, we don’t have a specific timeline we can share yet. But these are definitely things we take seriously, and we’ll plan them carefully based on user demand and overall product direction. If we see strong demand from users, we’ll absolutely prioritize them accordingly.

Thank you to the team at UGREEN for their time in this interview. As mentioned, the answers about were provided in their entirety and without prejudice. This will be a video soon that covers this, the tour of the facilities, as well as further discussion around the IDX6011 NAS Kickstarter and how this has been managed.

How Good is the Terramaster TOS 6 NAS Software?

TerraMaster’s TOS 6 represents the company’s most comprehensive evolution of its NAS operating system, delivering an interface and architecture that is redesigned both visually and structurally. Replacing the earlier TOS 5, it builds on user feedback from the last three hardware generations and now arrives preinstalled on systems such as the F4-425 Plus, F2-425, and F6-424, as well as the all-flash F8 SSD Plus. The system adopts the Linux Kernel 6.1 LTS, which improves memory handling, file system performance, and hardware compatibility across newer Intel and AMD processors. With over forty new functions and more than three hundred individual refinements, TOS 6 is positioned as a more capable and robust platform for modern data storage and multi-user environments. TerraMaster’s objective with this version is to combine an accessible setup process with enterprise-style administration tools, allowing users to deploy features such as ACL permissions, SMB multichannel, Hyper-Lock WORM protection, and advanced RAID management within a simplified interface. Although still developing its ecosystem when compared with long-established NAS vendors, TOS 6 signals a step toward bridging the gap between budget and professional-grade systems.

Terramaster TOS 6 – Design, GUI and UX

TOS 6 introduces a significantly redesigned interface that emphasizes simplicity and consistency while retaining the technical depth expected from a NAS management platform. The desktop layout has been decluttered, removing excess icons in favor of a single navigation bar that centralizes access to applications, settings, and the new “Start” shortcut menu. This layout, combined with subtle animation effects and theme customization options such as Night Mode and accent color selection, is intended to make the environment less visually overwhelming than previous releases. While the interface feels smoother and more responsive, some users may still find it utilitarian compared to the polished design language of DSM or QTS. Nevertheless, the decision to reduce visual clutter and allow personalized dashboards marks a meaningful progression toward a more user-centric control experience.

The control panel, which is the backbone of the system’s configuration layer, has undergone extensive structural improvement. It now allows users to jump between related settings without closing the current menu, effectively halving the time required to perform complex administrative tasks. The inclusion of a keyword search bar further simplifies access to hundreds of configuration options ranging from network tuning to caching policies. Real-time monitoring panels, including the resource manager and storage manager, remain integrated into the main interface, but TOS 6 refines them with more accurate live updates and adjustable widgets.

This customization extends to the new system dashboard, where users can drag and rearrange data modules to match their monitoring preferences. Despite these improvements, the GUI still presents a text-heavy design, particularly in areas dealing with drive management, which could be challenging for newcomers.

The user experience, while substantially enhanced, continues to cater more toward technically proficient users than beginners. Nearly every system element is accessible from the web interface, with contextual right-click menus providing file and folder actions similar to desktop OS environments. This native browser-based functionality eliminates the need for third-party explorers for most operations and allows complete administrative control without client software. However, the interface’s dense arrangement of settings can still appear intimidating for users expecting guided wizards or visualized workflows.

TerraMaster’s focus on efficiency and configurability, rather than aesthetic guidance, reflects a deliberate design choice favoring control and transparency. For experienced users, this approach offers depth and predictability, but it remains less forgiving to casual or first-time NAS owners.

Terramaster TOS 6 – Storage Services and File Services

Storage management within TOS 6 has evolved into a far more granular and flexible system. The platform supports both traditional RAID configurations and TerraMaster’s adaptive TRAID and TRAID+ systems, which allow mixed-capacity drives to be combined while retaining redundancy across one or two disks. This feature makes expansion and migration easier, particularly for users gradually upgrading storage capacity. RAID rebuilding efficiency has also improved through “fast repair,” a mechanism that prioritizes only data-occupied sectors rather than empty disk space, substantially reducing recovery times after drive replacement. The system now separates the operating system from storage volumes entirely, allowing users to install the OS on one or two designated drives, typically SSDs, to improve response speed and cache access performance. This separation not only increases system responsiveness but also helps to protect data pools from corruption caused by OS-level failures.

The volume creation process is more flexible than in previous iterations, supporting both Btrfs and EXT4 file systems alongside iSCSI targets for raw block-level storage. Btrfs, in particular, benefits from the Linux 6.1 kernel’s improved memory handling and snapshot reliability. The inclusion of Hyper-Lock WORM (Write Once, Read Many) in both Compliance and Enterprise modes offers organizations the ability to lock data for specific periods or indefinitely, preventing modification or deletion to meet audit or regulatory requirements.

Volume-level encryption can be enabled during creation, giving administrators the option to protect sensitive data without affecting system-level performance. The management interface also displays real-time disk health data and S.M.A.R.T. metrics, alerting users to failing drives through the Message Center and email notifications, minimizing downtime and data loss risks.

TOS 6’s file service layer emphasizes both accessibility and speed. SMB multichannel support, combined with link aggregation, allows the operating system to utilize multiple Ethernet ports simultaneously to multiply throughput on supported models, improving large file transfer rates in multi-user environments. Shared folder management includes advanced ACL permissions, extending beyond traditional read/write rules to thirteen distinct access types, providing fine-grained control for business use.

Native support for protocols such as SMB, AFP, NFS, FTP, and WebDAV ensures compatibility with Windows, macOS, and Linux systems, while local mounting enables users to attach external drives or even cloud-mapped directories that synchronize automatically. File management within the web interface now features a tab-based navigation system, a first among NAS platforms, enabling quick copy and move operations without opening multiple windows, reinforcing TerraMaster’s focus on operational efficiency.

Terramaster TOS 6 – Backups and Synchronisation

Backup management in TOS 6 consolidates all related tools into a single unified interface accessible from the desktop or the control panel. This centralized hub simplifies navigation between local, remote, and cloud-based backup options while maintaining compatibility with third-party systems. The platform supports Rsync for cross-NAS synchronization, Time Machine for macOS clients, and TerraMaster’s own Centralized Backup utility for deploying and scheduling protection across multiple TNAS and remote servers. Administrators can configure recurring snapshot tasks on individual volumes or shared folders, define retention policies, and even lock snapshots to prevent deletion within a specified period. While these snapshots are not substitutes for full backups, they provide a lightweight recovery mechanism that minimizes data loss in cases of user error or ransomware infection.

Local backup utilities have been expanded to support directory-level duplication, USB external drives, and iSCSI targets. This enables administrators to replicate data within the same device, between drives, or toward another NAS through the internal network. Although backing up within a single system cannot substitute true redundancy, it offers additional flexibility for temporary mirroring or fast internal restores. For users operating hybrid environments, TOS 6 integrates with major cloud providers using its CloudSync feature, which allows continuous bidirectional synchronization between TNAS and services such as Google Drive, Dropbox, OneDrive, and WebDAV storage. Mounted cloud directories appear as native local folders, simplifying file interaction and ensuring that any modifications are reflected remotely. The mounting mechanism also allows automatic synchronization of remote data without external applications, further streamlining multi-location workflows.

In terms of automation and security, backup tasks in TOS 6 can be scheduled to run incrementally or in real time, minimizing bandwidth usage and system load. Each task includes verification and logging, with the ability to send alerts on failure through the Message Center or by email. The inclusion of Hyper-Lock WORM at the backup level ensures archived backups cannot be altered for a defined compliance period, an important feature for business environments managing regulated data. Despite the lack of the same polish found in Synology’s Active Backup or QNAP’s Hybrid Backup Sync, TerraMaster’s solution achieves a comparable range of features for small-scale and mid-tier operations. The combination of flexible snapshot scheduling, cloud integration, and data-integrity verification makes TOS 6 a notable step forward from earlier releases and closes much of the functionality gap that existed between TerraMaster and its larger competitors.

Terramaster TOS 6 – Applications, Client Tools and Services

The application ecosystem in TOS 6 has expanded both in variety and integration depth, blending TerraMaster’s own utilities with third-party and open-source solutions. The App Center serves as the central hub for installing, updating, and managing applications, ranging from productivity tools and cloud clients to virtualization and multimedia services. Many of these applications are developed in-house, such as the Centralized Backup, File Manager, and Photo Gallery utilities, while others leverage established third-party frameworks like VirtualBox for virtualization and Portainer for container management. Users can deploy Docker containers directly from the interface or access the full registry for advanced workloads, making it possible to host additional media servers, AI indexing tools, or web applications. Although the ecosystem remains smaller than Synology’s Package Center or QNAP’s App Center, the available selection covers nearly all core NAS functions that general users and small business environments would require.

Client connectivity is also a strong component of the system’s service design. The TerraMaster desktop client for Windows and macOS allows users to discover NAS systems on the network, manage synchronized folders, and create automated transfer tasks. This complements the browser-based interface by offering a faster method for initiating replication jobs or file transfers between devices. Mobile applications are available for remote access, providing basic file management and media browsing functionality, though they remain limited compared to the desktop experience. One notable improvement in TOS 6 is the ability to download client tools directly from within the App Center rather than navigating to external links, streamlining deployment and maintaining version consistency across environments.#

In the area of multimedia and AI-driven services, TerraMaster has continued to refine its photo and video indexing utilities. The AI Photo Recognition tool, embedded within the Photo Gallery application, performs facial and object detection to organize content by identity or category. It uses metadata and machine learning libraries to recognize patterns across uploaded images, enabling faster search and auto-tagging capabilities. Video and photo thumbnails can be displayed directly within File Manager, which now supports large or small thumbnail scaling depending on user preference. For users requiring broader streaming capabilities, the system includes native support for Plex and Jellyfin through the App Center, allowing local or remote playback using widely adopted external platforms rather than proprietary ones. HDMI output remains inactive on TerraMaster NAS units, so these integrations rely solely on network streaming protocols.

System maintenance and troubleshooting services have also received attention in TOS 6. The platform’s security advisor can perform automated vulnerability checks, flagging weak passwords, exposed ports, or outdated configurations. Isolation Mode remains one of its more practical safety features, instantly disconnecting all non-administrative users and disabling PHP-based third-party apps to prevent intrusion. When users encounter system errors, they can utilize the integrated issue reporting tool, which generates diagnostic logs and can enable temporary remote support for TerraMaster engineers through an authentication key.

Although this feature should be used sparingly, it represents a more direct support pathway than previous versions. Taken together, these improvements show a gradual shift in TOS 6 toward professionalization, improving reliability and ease of management while still allowing extensive customization for experienced administrators.

Conclusion and Verdict

TOS 6 demonstrates that TerraMaster’s NAS platform has matured into a far more capable and structured ecosystem. The software now integrates a wide range of features that were once missing or underdeveloped, from advanced storage management and ACL permissions to cloud synchronization and AI-driven media tools. The interface redesign brings a measurable improvement in usability, and the decision to rebuild the system on the Linux Kernel 6.1 LTS ensures better hardware compatibility and long-term stability. However, it remains evident that the user experience still leans toward a more technical audience, with complex menus and limited guidance compared to the automated workflows found on Synology DSM or QNAP QTS. The system performs reliably, but its presentation and documentation could still benefit from refinement to fully appeal to non-specialist users.

Overall, TOS 6 is TerraMaster’s most complete and confident release to date, delivering a noticeable leap in speed, data protection, and operational consistency across the company’s NAS lineup. It now offers enough depth for small businesses, IT enthusiasts, and hybrid work setups while remaining open to third-party operating systems for those seeking additional flexibility. The platform still trails behind the larger ecosystems in app diversity and cloud integration polish, yet the progress made in this generation positions TerraMaster as one of the more serious alternatives in the mid-range NAS market. For users who value functionality and system control over visual refinement, TOS 6 provides a stable and expandable foundation that indicates TerraMaster is steadily closing the gap with its more established competitors.
