UGREEN DH4300 PLUS vs UniFi UNAS 4 – Which Should You Buy?

The UniFi UNAS 4 and the UGREEN DH4300 Plus are being compared because they currently occupy a very similar part of the 4-bay NAS market, with both systems targeting buyers who want a relatively affordable turnkey storage solution with 2.5GbE connectivity, modern desktop design, and a lower entry price than many traditional NAS brands. On paper, they are close enough in price to be direct alternatives, but in practice they approach NAS deployment very differently. The UniFi UNAS 4 is built around tight integration with the wider UniFi ecosystem and focuses primarily on straightforward storage, backup, and remote file access, whereas the UGREEN DH4300 Plus is designed as a broader standalone NAS platform with more memory, a more powerful ARM processor, HDMI output, and a wider range of applications and services. That makes this comparison relevant not just because of the hardware and price overlap, but because each system reflects a different idea of what an entry to mid-range 4-bay NAS should be in 2026.

UniFi vs UGREEN NAS – Brand vs Brand

Before I dig into which of the DH4300 or UNAS 4 is best for you, it is worth highlighting again that these are two comparatively new players in the NAS scene (compared with long time multi-decade vetrans such as Synology, QNAP, Asustor and Terramaster), so let’s talk about their priorities and focus at a brand level. Both UGREEN and UniFi have entered the NAS sector from distinct starting points and continue to move in different directions, each targeting a particular type of user. UniFi’s UNAS series delivers consistency, predictable performance, and dependable integration with the broader UniFi ecosystem. Its software is stable, lightweight, and well-suited to users who prioritize straightforward storage management, reliable data handling, and unified control across routers, switches, and surveillance systems. While the hardware is limited to fixed ARM configurations and non-expandable memory, it is efficient, quiet, and designed for continuous operation with minimal maintenance. For organizations already invested in UniFi infrastructure, the UNAS systems provide a logical expansion that keeps management centralized and operational risk low. However, their value depends heavily on ecosystem synergy; outside of that environment, the systems remain competent but relatively inflexible standalone NAS options.

UGREEN’s NASync platform, on the other hand, appeals to users seeking broader performance capability and independence. Its x86-based models, upgradable memory, and open software environment allow it to serve as a hybrid between NAS and compact server, capable of running applications, containers, and virtual machines alongside storage tasks. The design language is more suited to individual or small business use than datacenter deployment, but the hardware range—from ARM to Core i5—covers a far wider performance spectrum than UniFi’s. Software maturity continues to evolve quickly, with new features added frequently, and the systems provide extensive compatibility with third-party clients and backup services. The trade-off is that long-term reliability and enterprise-level security validation are still developing.

Ultimately, UniFi NAS suits users who already rely on UniFi’s networking ecosystem and value simplicity, predictability, and centralized management, while UGREEN NAS caters to those prioritizing flexibility, compute power, and open software capability. Both brands have lowered the entry barrier into reliable NAS ownership, but they embody opposing philosophies: UniFi focuses on integration and control, whereas UGREEN emphasizes capability and independence.

UGREEN DH4300 vs UniFi UNAS 4 – Design and Storage

From a physical design perspective, these 2 NAS systems take very different approaches. The UniFi UNAS 4 has a taller, narrower chassis with a more vertical layout, while the UGREEN DH4300 Plus uses a more cubic desktop design that will look more familiar to buyers coming from Synology, QNAP, or Asustor hardware. The UniFi system is also available in black or white, which gives it a more deliberate visual identity within the wider UniFi product range, whereas the UGREEN keeps to a more conventional single-finish enclosure. In both cases, the chassis material is primarily plastic, so neither is especially premium in material terms, but each is clearly trying to prioritize compactness and low manufacturing cost rather than metal construction.

The drive arrangement is also notably different. The UniFi UNAS 4 places its 4 SATA bays in the base of the chassis, with the drives inserted from underneath, while the UGREEN DH4300 Plus uses a top-loaded vertical bay arrangement hidden under a removable outer shell. Neither system uses a particularly enterprise-focused tray design, and neither is really built around frequent hot-swap use in the same way as more expensive rackmount or prosumer NAS systems. That said, the UniFi trays are easier to describe as straightforward click-in drive carriers, while the UGREEN trays feel more budget-oriented in construction and do not leave the same impression of robustness as more established NAS brands.

In storage flexibility, the UniFi has the more ambitious configuration. Alongside its 4 SATA bays, it also includes 2 dedicated M.2 NVMe slots for SSD cache. That gives it an advantage in hybrid storage architecture, since the hard drives can be used for capacity while the NVMe media handles read and write cache duties. The UGREEN DH4300 Plus does not include M.2 storage slots, so any SSD deployment has to consume one or more of the main SATA bays, which reduces total storage capacity. At the same time, UniFi currently limits those NVMe bays to cache use rather than general storage pools, so the practical advantage is still narrower than the raw hardware layout suggests.

The 2 brands also differ in RAID and storage management philosophy. The UGREEN supports a broader list of RAID modes, including JBOD, Basic, RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10, which gives it more deployment flexibility for different user priorities around performance, redundancy, or simple linear storage. The UniFi platform supports RAID 5, RAID 6, and RAID 10, but its overall storage structure is more controlled and less flexible, with a stronger focus on a simplified single storage pool approach. For buyers who want fewer decisions and a cleaner setup process, that may be acceptable, but for users who want more granular control over how storage is arranged, the UGREEN is less restrictive.

In pure storage potential, the UGREEN is also easier to quantify because it officially supports up to 128TB across 4 bays using 32TB drives, whereas UniFi focuses more on supported drive compatibility and cache pairing than on headline raw capacity figures. The UniFi does have the practical advantage of SSD caching built in, which can improve responsiveness in repeated access and write-heavy workloads, but the UGREEN has the simpler storage proposition overall and does not tie part of its internal design to optional accessories such as UniFi’s separate M.2 tray approach. As a result, the UniFi has the more distinctive and technically layered storage design, while the UGREEN has the more conventional and broadly flexible one.

UniFi UNAS4 vs UGREEN DH 4300 – Internal Hardware & Connections

Internally, the UGREEN DH4300 Plus has the stronger hardware specification. It uses an 8-core Rockchip ARM processor based on Cortex-A76 and Cortex-A55 cores running at up to 2.0GHz, alongside 8GB of LPDDR4X memory and 32GB of eMMC for the system. By comparison, the UniFi UNAS 4 uses a quad-core ARM Cortex-A55 processor at 1.7GHz with 4GB of memory. Both systems are clearly built around low-power ARM architecture rather than x86 processing, but the UGREEN has the more capable platform on paper and offers more headroom for multitasking, background services, and broader software functionality.

The UniFi system does, however, counter with a more unusual internal layout. In addition to its 4 SATA bays, it includes 2 M.2 NVMe slots dedicated to SSD cache, which gives it a storage acceleration feature that the UGREEN does not match natively. For users dealing with repeated file access, background synchronization, or burst-heavy write activity, that cache support has practical value. The UGREEN relies entirely on its 4 SATA bays for storage media, so although its CPU and memory are stronger, its internal storage architecture is less advanced in terms of tiered storage.

External connectivity is broader on the UGREEN. It includes 1x 2.5GbE LAN port, HDMI output at up to 4K 60Hz, 1x front USB 3.2 Gen 1 port at 5Gb/s, and 2 additional USB-A 5Gb/s ports. The UniFi UNAS 4 is much more limited, offering 1x 2.5GbE RJ45 port and 1x 5Gb/s USB-C port. This narrower I/O profile reflects the fact that UniFi has positioned the UNAS 4 as a focused network storage appliance rather than a multi-role NAS for media output, peripheral attachment, or application expansion. In direct hardware terms, the UGREEN is better equipped for users who expect more than basic file serving.

Power and deployment also separate these 2 systems. The UniFi UNAS 4 supports PoE+++ and includes a 90W PoE adapter, which allows both power and network connectivity over a single cable in supported environments. That is unusual in this part of the NAS market and makes it particularly relevant for users already invested in UniFi switching infrastructure or those deploying hardware in locations where simplified cabling matters. The UGREEN uses a more conventional external power arrangement, which is less distinctive but also less dependent on network infrastructure choices. Therefore, the UGREEN has the stronger internal compute hardware and broader physical connectivity, while the UniFi has the more specialized deployment advantage.

UGREEN DH4300 vs UniFi UNAS 4 – Software & Services

The biggest difference between these 2 NAS systems is not the chassis or the processor, but the software scope. The UniFi UNAS 4 runs UniFi Drive and is clearly built around a narrower storage-first brief, with support for SMB, NFS, snapshots, file encryption, Time Machine, share links, user groups, remote backup, cloud backup targets, and client apps. It covers the main NAS fundamentals expected by home users and small offices, but it does so within a more controlled environment that places simplicity and consistency ahead of feature breadth. The UGREEN DH4300 Plus, running UGOS Pro, aims much wider and includes not only file serving and backup tools, but also multimedia applications, container support, HDMI-based media playback, AI-assisted photo features, and broader service depth overall.

For pure storage management, UniFi Drive is cleaner and more focused, particularly for users who want the NAS to act primarily as private cloud storage, backup target, and centralized file repository. Its interface is built to align with the broader UniFi platform, and that gives it an advantage for users already running UniFi networking equipment and remote management tools. However, that same focus also means the UNAS 4 is less flexible as a general-purpose NAS. The UGREEN platform does not have the same ecosystem tie-in, but it operates more independently and gives the user more scope to use the system for different workloads beyond file storage.

Application support is where the gap becomes more obvious. The UGREEN DH4300 Plus supports Docker and has a noticeably broader service layer for media, backup, and user applications. That creates options for running third-party software, home media tools, and more customized services that simply are not part of the UniFi approach. The UniFi UNAS 4 does not currently try to compete in that area and instead presents itself as a dedicated NAS platform rather than an application host. For some users that will be a limitation, while for others it will be a benefit, because it reduces complexity and keeps the system centered on storage tasks rather than mixed workload experimentation.

In practical terms, the software decision comes down to whether the buyer values depth or focus. The UGREEN DH4300 Plus offers the broader NAS software experience and is better suited to users who want more features, more applications, and more ways to extend the system over time. The UniFi UNAS 4 offers the more controlled and storage-specific platform, with the clearest advantage appearing when it is deployed inside an existing UniFi environment. As a result, the UGREEN software stack is more versatile, while the UniFi software stack is more specialized.

UniFi UNAS 4 vs UGREEN DH4300 NAS – Conclusion & Verdict

Taken as a whole, these 2 systems are aimed at a similar buyer in price terms, but they are not trying to solve the same problem in the same way. The UniFi UNAS 4 is a more specialized NAS that focuses on storage, backup, remote access, and integration within the UniFi ecosystem. The UGREEN DH4300 Plus is a broader standalone NAS that gives the user more hardware resources, more software flexibility, and a wider overall role in the network. That difference matters more than the relatively small gap in price, because in day to day use they will appeal to different priorities. The UniFi UNAS 4 makes more sense for buyers who already use UniFi switches, gateways, and management tools, or for those who specifically want a NAS that stays focused on file storage instead of trying to become a media server or container host. Its built in NVMe cache support and PoE+++ deployment give it some useful differentiators, and its simpler software scope will suit users who want a more controlled experience. However, outside of the UniFi ecosystem, some of its strengths become less important, while its limitations in application support, connectivity, and hardware power become harder to ignore.

The UGREEN DH4300 Plus is the better fit for users who want a more traditional all-round NAS. It has the stronger CPU, more memory, broader external connectivity, more RAID options, HDMI output, Docker support, and a software platform with more room to scale into multimedia, backup variety, and third party services. It is the more capable choice for mixed home and small business use, particularly for buyers who are not tied to any specific network brand and want their NAS to handle more than just centralized storage. It is also the easier system to recommend to users comparing it against other established 4-bay NAS platforms in the same price bracket. So, in direct usage terms, the UniFi UNAS 4 is better for UniFi-centric deployments, cleaner storage-first use, and buyers who value NVMe caching and PoE-based installation. The UGREEN DH4300 Plus is better for users who want stronger hardware, more software features, better connectivity, and a wider long term usage profile. If the question is which is the better pure value NAS for the largest number of users, the UGREEN DH4300 Plus is the stronger overall option. If the question is which fits better into a UniFi-led network and a simpler storage-focused role, the UniFi UNAS 4 is the more appropriate choice.

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.
