The UniFi Dream Machine Beast arrives as a more serious entry in the Dream Machine range, and that immediately raises the main question: who is it actually for? Existing UniFi users may look at it as a possible upgrade from a UDM Pro, UDM SE, or UDM Pro Max, while new buyers may see it as a way to start with a more capable console from day 1. On paper, it is clearly built for larger and busier networks, but that does not automatically make it the right choice for every UniFi setup. Whether the Dream Machine Beast makes sense depends less on the headline specification and more on the network around it. For some users, it may offer useful headroom for faster internet, heavier security processing, larger Protect installations, or wider UniFi management. For others, it may be more hardware than the deployment can realistically use, especially once the cost of switches, cabling, cameras, access points, and redundancy are taken into account. This article looks at where the Beast is a practical upgrade, where it may be excessive, and what trade-offs should be considered before buying.
The UniFi Dream Machine Beast is best viewed as a higher-capacity UniFi OS console for larger UniFi networks, rather than a default upgrade for every Dream Machine user. Its main advantages are the 8-core Arm v9 processor, 16GB of memory, 10GbE RJ45 ports, 10G SFP+ connectivity, 25G SFP28 support, 25Gbps-class IDS/IPS throughput, support for 750+ managed UniFi devices, 7,500+ concurrent clients, and 2 3.5-inch NVR bays for larger UniFi Protect deployments. These upgrades make it a more suitable option for businesses, multi-site networks, heavier camera installations, faster WAN environments, and users who are starting to outgrow the UDM Pro, UDM SE, or UDM Pro Max. It also makes sense where security inspection, VPN use, traffic analysis, and UniFi application hosting are all expected to run at a larger scale on the same appliance. However, the Beast is not a simple plug-in upgrade for every setup. The $1,499 price, lack of PoE, internal non-removable PSU, and dependency on wider 25GbE infrastructure all make the total cost higher than the unit alone suggests. Users with mostly 1GbE, 2.5GbE, or 10GbE networks may not see enough practical benefit to justify the move, especially if their existing Dream Machine is not close to its limits. In many smaller UniFi deployments, the better use of budget may be a UDM Pro, UDM SE, or UDM Pro Max combined with stronger switches, more access points, improved camera coverage, larger storage, or backup power. The Dream Machine Beast is therefore a strong option for larger and more demanding UniFi environments, but it should be bought with a clear network plan rather than as an automatic upgrade.

A key hardware change in the UniFi Dream Machine Beast is its move to an 8-core Arm v9 processor running at 2.1GHz. This is a notable step up from the older Dream Machine models, such as the UDM SE, which uses a quad-core Arm Cortex-A57 at 1.7GHz with 4GB of memory. The Beast is built around Arm Neoverse N2 architecture, which Arm describes as its 1st Arm v9 infrastructure CPU, designed for cloud-to-edge workloads with improved performance per watt and a claimed 40% scalar performance uplift over Neoverse N1.
In practical terms, the CPU matters because the gateway is not just passing traffic from 1 port to another. It may also be handling firewall rules, IDS/IPS inspection, VPN traffic, DPI, policy routing, SD-WAN, VLANs, and UniFi application management at the same time. The supplied specification lists IDS/IPS throughput at 24.9Gbps, which is far beyond the 3.5Gbps figure associated with the UDM Pro class. That does not mean every user will need this level of processing headroom, but for larger networks it reduces the chance that security features or encrypted traffic become the main limit before the ports themselves do.
The Dream Machine Beast makes a clear jump in physical connectivity compared with the smaller Dream Machine models. Instead of treating 10GbE as the higher-end connection, it uses 10GbE RJ45 as the baseline for its main LAN ports, alongside 10G SFP+ and 25G SFP28 connectivity. This matters because it gives the unit enough port flexibility to sit between faster WAN services, high-speed switches, NAS systems, and larger UniFi deployments without immediately forcing everything through a single 10GbE bottleneck.
The 25G SFP28 port is the more significant part of the design, as it gives the Beast room to aggregate traffic from larger networks rather than simply serve a handful of local devices. For users with multi-gig internet, large camera deployments, heavy internal routing, or multiple downstream switches, this creates a more capable central gateway than the UDM Pro Max. However, the benefit depends heavily on the rest of the network. A 25GbE port only becomes useful when switches, cabling, transceivers, and connected systems can also take advantage of it.
The Dream Machine Beast also increases system memory to 16GB, which is a practical upgrade when compared with smaller Dream Machine models. RAM is not as visible as the ports on the front of the unit, but it matters when the console is managing routing, firewall rules, VPNs, IDS/IPS, traffic identification, UniFi Network, UniFi Protect, and other UniFi applications at the same time. More memory gives the system more room to handle these services without the same pressure on resources as deployments grow.
In real terms, this is reflected in the stated management limits. The Beast is rated for 750+ managed UniFi devices and 7,500+ simultaneous connected users, while also supporting larger Protect deployments of up to 100 HD cameras, 60 2K cameras, or 40 4K cameras. Those figures put it in a different class from a typical small office or prosumer Dream Machine setup. The benefit is not just that the Beast can run faster, but that it is better equipped to keep multiple UniFi workloads active at once without becoming constrained as quickly.
The Dream Machine Beast includes 2 3.5-inch NVR HDD bays, which makes storage a more serious part of the appliance rather than a minor add-on. This is most relevant for UniFi Protect users, because camera recording is where local storage capacity has the biggest day-to-day impact. With support for up to 100 HD cameras, 60 2K cameras, or 40 4K cameras, the Beast is clearly intended to handle larger surveillance deployments than a basic Dream Machine setup.
The 2-bay design also gives users more flexibility than a single-drive console. It allows for higher total recording capacity or a redundant storage configuration, depending on how the system is deployed. The built-in 128GB SSD is separate from this and is used to keep the UniFi OS experience responsive rather than acting as the main video archive. This does not turn the Beast into a dedicated high-bay NVR, but it does make it more practical for sites that want gateway, management, and Protect recording in 1 rackmount device.
The main drawback with the Dream Machine Beast is the price. At the quoted $1,499 figure from the launch material, it sits well above the rest of the Dream Machine range. For comparison, the UDM Pro is listed by Ubiquiti’s UK store at £300 before VAT, while the UDM SE is listed at £395 before VAT and the UDM Pro Max at £475 before VAT. Those models are clearly lower in throughput and capacity, but the difference still matters because the Beast is not a small step up in cost.
That makes the buying decision less about whether the Beast is technically better, and more about whether the network will actually use what it offers. A UDM Pro Max already provides 5Gbps IPS routing, 2,000+ client support, 200+ UniFi device support, and 2 NVR drive bays, which is still enough for many UniFi deployments. The Beast makes more sense when the extra routing capacity, larger client count, 25GbE connectivity, and higher Protect ceiling are genuinely required. For smaller sites, the money saved by choosing a lower Dream Machine could be more useful if spent on switches, access points, cameras, or backup power instead.
The Dream Machine Beast does not include PoE ports, which is a noticeable omission for a device at this price and scale. This does not affect its role as a gateway, firewall, UniFi OS console, or NVR, but it does mean that access points, cameras, door access hardware, phones, and smaller UniFi devices will need power from a separate PoE switch, injector, or other power source. For larger deployments this may not be a major issue, because a dedicated PoE switch would usually be part of the design anyway.
The drawback is more obvious for users upgrading from a Dream Machine model that already includes PoE, such as the UDM SE. Even a small number of PoE ports can be useful for directly powering a nearby access point, test device, camera, or compact downstream switch. On the Beast, the lack of PoE reinforces the idea that it is not intended to be a self-contained all-in-one network box. It is better understood as the central gateway and controller for a wider UniFi installation, rather than a device that can power much of that installation on its own.
The Dream Machine Beast uses an internal AC/DC power supply rather than a removable PSU module. It does support DC power backup through UniFi’s RPS system, which gives it a path for power failover when used with the required external hardware. However, this is not the same as having a hot-swappable or easily replaceable PSU built into the unit itself. If the internal supply fails, servicing is likely to be less convenient than it would be on a rackmount device with a standard removable power module.
This matters more because the Beast is aimed at larger and more business-critical UniFi environments. At this level, some buyers may expect either dual onboard PSUs or at least a removable single PSU design for easier replacement and reduced maintenance time. The RPS option helps with continuity, but it also adds another device to the rack and another cost to the overall setup. For users planning around uptime, this is an area where the Beast is functional, but not as service-friendly as some enterprise-style rack hardware.
The Dream Machine Beast’s 25GbE capability is useful, but it can also change the scale of the upgrade. To take proper advantage of a 25GbE gateway, the rest of the network needs to be able to feed it and receive traffic from it at similar speeds. That usually means 25GbE-capable switches, suitable SFP28 modules or DAC cables, and potentially faster links to servers, NAS systems, or aggregation switches. Without that supporting hardware, the 25GbE port may end up being useful mainly as future headroom rather than something the network benefits from immediately.
This is where the Beast can become more expensive than it first appears. A network built around 2.5GbE or 10GbE copper may not need to move to 25GbE yet, especially if most endpoints are access points, cameras, desktops, or smaller servers. In those cases, a lower-cost Dream Machine paired with better 2.5GbE or 10GbE switching may be the more balanced upgrade. The Beast makes more sense when the wider network is already moving toward 25GbE, or when there is a clear plan to scale into it, rather than when the 25GbE port is the only part of the setup ready for that speed.
The UniFi Dream Machine Beast is a stronger fit for users who have already reached the limits of the existing Dream Machine models, or who can clearly see those limits approaching. Its faster processor, 16GB of memory, 25GbE connectivity, high IDS/IPS throughput, larger UniFi management capacity, and 2 NVR drive bays all point toward larger networks with heavier traffic, more cameras, more clients, or more demanding security features. In that context, it is not simply a faster UDM Pro Max. It is a more substantial gateway and UniFi OS console for deployments that need more headroom.
For everyone else, the value is less clear. The higher price, lack of PoE, internal non-removable PSU, and likely need for wider 25GbE infrastructure all make it a device that should be bought with a specific network plan in mind. Users running smaller UniFi systems, mostly 1GbE to 10GbE networks, or modest Protect installations may get better value from a UDM Pro, UDM SE, or UDM Pro Max with money left for switches, access points, storage, or backup power. The Beast is best judged as a targeted upgrade for larger UniFi environments, not as the default Dream Machine for every buyer.

At NAB 2026 in Las Vegas, Ubiquiti Inc. showcased a number of rackmount UniFi devices that have not yet been formally announced or released. These systems were presented alongside existing products, making it necessary to distinguish between current hardware and what appears to be forthcoming or experimental equipment. The devices observed represent a noticeable increase in port density, throughput capability, and overall positioning compared to the current UniFi lineup.
Four specific devices stand out from this showcase: the UniFi Dream Machine Beast, the Enterprise Fortress Gateway Core, the Enterprise 100G switch, and the Enterprise S PoE switch. Based on available observations and supporting information, these products appear to form a cohesive expansion of the UniFi ecosystem into higher-performance enterprise and datacenter environments. However, specifications remain unconfirmed and should be considered provisional until officially published.
The UniFi Dream Machine BEAST appears to be a significant evolution of the existing Dream Machine platform, extending beyond the capabilities of current models such as the UniFi Dream Machine Pro Max. Based on observed hardware, this device integrates substantially higher port density, particularly in 10G and 25G connectivity, while also introducing onboard storage via dual SATA bays. This suggests a continued emphasis on combining routing, switching, and application hosting within a single appliance, including UniFi OS services such as Protect and other controller-based functions.
Compared to previous Dream Machine models, the BEAST shifts closer toward an enterprise-focused deployment, particularly in environments requiring direct multi-gigabit connectivity without reliance on additional aggregation switches. However, key system details such as CPU architecture, memory capacity, and throughput performance remain unconfirmed. The absence of official documentation indicates that this device is still in a pre-release or prototype stage, and its final positioning within the UniFi portfolio is not yet defined.
| Feature | Specification |
|---|---|
| 2.5G RJ45 Ports | 2 |
| 10G RJ45 Ports | 8 |
| 10G SFP+ Ports | 2 |
| 25G SFP28 Ports | 2 |
| Storage | 2 × SATA drive bays |
| Form Factor | Rackmount |
| Software | UniFi OS (expected) |
| CPU / RAM | Not confirmed |
| Release Status | Unreleased |
The UniFi Enterprise Fortress Gateway Core appears to extend the capabilities of the existing UniFi Enterprise Fortress Gateway into a significantly higher performance tier. While the current Enterprise Fortress Gateway is already positioned as a high-end UniFi routing platform, the Core variant introduces substantially greater port density and bandwidth, including support for 100G connectivity. This suggests a shift from traditional edge gateway roles toward deployment in core or aggregation layers within larger enterprise or datacenter environments.
The observed hardware indicates a design focused on high-throughput routing and multi-layer network integration, with a combination of 10G copper, 25G SFP28, and 100G QSFP28 interfaces. This represents a notable departure from existing UniFi gateway designs, which typically rely on lower port counts and external switching for aggregation. As with the Dream Machine BEAST, critical specifications such as processing architecture, memory configuration, and pricing remain undisclosed, reinforcing the likelihood that this device is still in a pre-release stage.
| Feature | Specification |
|---|---|
| 2.5G RJ45 Ports | 2 |
| 10G RJ45 Ports | 8 |
| 25G SFP28 Ports | 4 |
| 100G QSFP28 Ports | 4 |
| Power Supply | Dual redundant |
| Form Factor | Rackmount |
| CPU / RAM | Not confirmed |
| Release Status | Unreleased |
The UniFi Enterprise 100G appears to be a high-density aggregation or spine switch designed for environments requiring large-scale bandwidth distribution. Its configuration, centered around 25G access ports and 100G uplinks, aligns with common leaf-spine architectures used in enterprise and datacenter networks. Within the current UniFi portfolio, the closest comparison would be aggregation-focused switches such as the UniFi Switch Enterprise Aggregation, although the observed specifications of this device significantly exceed existing models in both port count and total throughput capacity.
This device is likely intended for deployment deeper within network infrastructure rather than at the edge, acting as a central switching layer connecting multiple high-speed access or distribution switches. The combination of 48 × 25G and 6 × 100G ports suggests a focus on scalability and backbone connectivity rather than end-device access. As with the other devices observed, no official documentation, pricing, or detailed hardware specifications have been released, and its final role within the UniFi ecosystem remains unconfirmed.
| Feature | Specification |
|---|---|
| 25G SFP28 Ports | 48 |
| 100G QSFP28 Ports | 6 |
| Form Factor | Rackmount |
| Switching Role | Aggregation / Spine |
| Cooling | Not confirmed |
| Power | Not confirmed |
| Release Status | Unreleased / Prototype |
The UniFi Enterprise S appears to be a high-density access switch focused on multi-gigabit connectivity and high-power PoE delivery. Its configuration combines a large number of 2.5G and 10G copper ports, all supporting PoE+++, alongside 25G uplinks for upstream connectivity. Within the current UniFi lineup, there is no direct equivalent, although products such as the UniFi Switch Pro XG 48 PoE operate in a similar space with lower overall port density and more limited PoE capability. The Enterprise S extends this concept by standardising high-power PoE across all access ports.
This design suggests deployment in environments with dense endpoint requirements, including wireless access points, cameras, and AV equipment, where both bandwidth and power delivery are critical. The combination of 2.5G and 10G ports allows for flexibility across different device classes, while the inclusion of 25G uplinks supports integration into higher-speed aggregation layers. As with the other devices observed, there is no confirmed information regarding total power budget, internal hardware, or release timeline, and the device should be considered pre-release.
| Feature | Specification |
|---|---|
| 2.5G RJ45 PoE+++ Ports | 32 |
| 10G RJ45 PoE+++ Ports | 16 |
| 25G SFP28 Ports | 4 |
| PoE Standard | PoE+++ (802.3bt) |
| Power Budget | Not confirmed |
| Form Factor | Rackmount |
| Cooling | Not confirmed |
| Release Status | Unreleased / Prototype |
The four devices observed at NAB 2026 indicate a broader shift in the UniFi portfolio toward higher-performance networking tiers. Collectively, they introduce increased port density, support for 25G and 100G connectivity, and in some cases, significantly expanded power delivery capabilities. Compared to currently available products such as the UniFi Enterprise Fortress Gateway and UniFi Dream Machine Pro Max, these systems represent a move beyond traditional edge and SMB-focused deployments into roles typically associated with enterprise core, aggregation, and high-density access layers.
However, all four devices remain unannounced and lack confirmed specifications, pricing, and release timelines. As a result, their final positioning and availability cannot be determined with certainty. While the observed hardware suggests a structured expansion into a more complete end-to-end networking stack, any conclusions remain provisional until formal details are released by Ubiquiti Inc..

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.
|
|
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.

|
|
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.
|
|
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.
|
|
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.
|
|
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.

Ubiquiti has introduced the UniFi AirWire, a WiFi 7 client adapter designed to address one of the more limited areas of current WiFi 7 deployment: the client side. While WiFi 7 access points and routers have been marketed heavily around Multilink Operation, many currently available client devices still rely on single-radio implementations that switch between bands rather than maintaining simultaneous links. The AirWire is positioned as a dedicated external client that aims to deliver true STR MLO operation across 5 GHz and 6 GHz, with Ubiquiti claiming improved throughput, lower latency, and better resilience than conventional integrated client hardware.
At a hardware level, the AirWire is a USB-C connected WiFi 7 adapter with a 4-stream design, support for 5 GHz and 6 GHz 2 x 2 MU-MIMO operation, and a quoted uplink capability of up to 5.8 Gbps on 6 GHz and 4.3 Gbps on 5 GHz. It also adds a high-gain antenna design and a dedicated scanning radio for real-time spectrum analysis. At $199, this places it well above the cost of generic USB wireless adapters, but it is also targeting a more specific role: enabling multi-gigabit wireless client connectivity in environments that already have the access point infrastructure to support it.
You can buy the Airwire via the link below – doing so will result in a small commission coming to me and Eddie at NASCompares, and allows us to keep doing what we do!
The UniFi AirWire has a noticeably different physical design to the compact USB WiFi adapters that are typically associated with desktop or laptop client upgrades. At 117 x 117 x 42.5 mm and 537 g, it is much closer in appearance to a standalone wireless bridge or directional client than a conventional dongle. That larger enclosure is directly tied to its intended function, as Ubiquiti is clearly building around higher power operation, larger antenna structures, and the thermal requirements that come with sustained WiFi 7 activity across multiple radios.
|
|
The housing is made of polycarbonate and includes a fold-out top section that appears to be part of the antenna assembly and directional positioning of the unit. This gives the AirWire a more deliberate deployment profile, where placement and orientation are likely to matter more than they would with an internal laptop radio or a low-profile USB adapter. On the front, there is also a 0.96-inch status display, which provides at-a-glance information during setup and operation without needing to rely entirely on software feedback from the host system.
|
|
From a practical standpoint, the design reflects that this is not intended to be an invisible add-on for casual wireless use. It is an external client device built to sit on a desk or near a workstation, with a form factor that prioritizes radio performance and signal handling over portability. That makes it less discreet than mainstream client adapters, but it also aligns with the product’s stated purpose as a high-performance WiFi 7 endpoint for users trying to push beyond the limitations of standard integrated wireless hardware.
Internally, the UniFi AirWire is built around a dual-band WiFi 7 architecture that focuses entirely on 5 GHz and 6 GHz operation, without any 2.4 GHz support. Ubiquiti rates the device as a 4-stream client, split across 2 x 2 MU-MIMO on 5 GHz and 2 x 2 MU-MIMO on 6 GHz.
This layout is central to its stated role as an STR MLO client, allowing both bands to be active simultaneously rather than relying on the more common single-radio behaviour seen in many current WiFi 7 client devices.
Ubiquiti also specifies a high-gain antenna design, with 11 dBi quoted on both 5 GHz and 6 GHz, which is significantly more aggressive than the antenna arrangements found in most integrated laptop or mobile WiFi hardware. Alongside this, the AirWire includes a dedicated scanning radio for real-time spectral analysis. That separate scanning capability is notable because it suggests the unit is not just focused on link speed, but also on monitoring local RF conditions and interference in parallel with normal client operation.
The trade-off for that hardware approach is power and thermals. Ubiquiti lists maximum power consumption at 18 W, with USB PD 5/9/12V support and separate normal and performance power profiles. In practical terms, that places the AirWire closer to a compact external network appliance than a typical USB wireless adapter. It also helps explain the larger chassis, the need for external power flexibility, and the expectation that sustained performance operation will demand more cooling headroom than a smaller bus-powered client device could realistically provide.

The UniFi AirWire connects to the host system over USB-C, but from a networking perspective it is presented as a 5 GbE interface over USB 3.2 Gen 2. That distinction matters, because although the wireless side of the device is rated far higher in combined theoretical bandwidth, the host connection places an upper practical ceiling on what can be delivered to the attached PC, laptop, or workstation. In effect, the AirWire is designed to behave more like an external multi-gig network adapter than a conventional USB WiFi dongle.
On the wireless side, the AirWire operates on 5 GHz and 6 GHz only, with support for WiFi 7, WiFi 6, WiFi 5, and 802.11n data rates across a wide range of channel widths. Ubiquiti lists support for EHT 20/40/80/160/240/320 MHz, alongside HE, VHT, and HT modes on earlier standards. The maximum quoted link rates are 5.8 Gbps on 6 GHz using 320 MHz bandwidth and 4.3 Gbps on 5 GHz using 240 MHz bandwidth, though actual results will depend heavily on access point capability, spectrum availability, regional channel restrictions, and signal conditions.
Power delivery is also part of the connection design. Ubiquiti specifies USB PD 5/9/12V support, with 15 W in normal mode and 20 W in performance mode, while maximum device power consumption is listed at 18 W. This means that, depending on how the host system is connected and powered, full performance operation may require more than a single low-power USB port can reliably provide. That makes cable quality, port specification, and available USB power budget more relevant here than they would be for standard client adapters.
The AirWire also includes support for wireless meshing and real-time spectral analysis, which extends its connection role beyond basic client access. In a UniFi environment, setup is intended to be handled through UniFi AutoLink for rapid onboarding, reducing the need for separate client-side software installation. Even so, the broader connection experience will still depend on the surrounding infrastructure, particularly whether the connected UniFi access point supports the required WiFi 7 and 6 GHz features needed for the AirWire to operate in the way it is being marketed.

The UniFi AirWire is a more specialised product than its USB-C connection initially suggests. Rather than serving as a low-cost way to add basic WiFi 7 support to a system, it is designed to address a specific gap in the current client ecosystem: the lack of widely available true multi-radio MLO hardware on the device side. Its value therefore depends less on headline wireless specifications alone and more on whether the surrounding network environment is already capable of taking advantage of simultaneous 5 GHz and 6 GHz operation, wider channel support, and multi-gigabit client throughput.
On that basis, the AirWire appears to be an interesting but clearly targeted piece of hardware. The larger chassis, higher power requirements, directional design, and likely dependency on a strong WiFi 7 6 GHz deployment mean it is not a universal client upgrade for every user. However, for users already invested in UniFi WiFi 7 infrastructure and looking for a higher performance external client than the current mainstream market provides, it introduces a form factor and feature set that are still relatively uncommon. Whether that translates into a meaningful real-world advantage will depend on testing, particularly around sustained throughput, latency behaviour, thermal limits, and the practical impact of STR MLO outside of ideal conditions.

The UniFi UNAS 4 is Ubiquiti’s desktop 4 bay NAS and part of the company’s growing UniFi storage portfolio. Positioned as a compact network storage appliance, it is designed to provide centralized file storage, backups, and shared access within a local network, while also integrating with the wider UniFi management platform. The 4 bay form factor is widely considered a practical starting point for NAS deployments, offering enough capacity for RAID redundancy while maintaining a relatively small physical footprint suitable for offices, home labs, and small business environments. At $379, the UNAS 4 enters the market as a relatively affordable turnkey NAS that includes both hardware and the UniFi Drive software platform. The system combines traditional SATA storage bays with NVMe SSD caching support and 2.5GbE networking, while also introducing PoE+++ power as a deployment option. On paper, the device aims to deliver a straightforward storage solution that focuses on core NAS functionality rather than attempting to compete directly with more feature heavy platforms.
TLDR: The UniFi UNAS 4 is a compact $379 4 bay NAS aimed at straightforward file storage and backups, with a clean UniFi oriented deployment that includes PoE+++ power plus data over a single cable and a bundled 90W adapter for non PoE setups. It combines 4 SATA bays with 2 M.2 NVMe slots for SSD caching, simple click and load drive trays, and a small front status display, while UniFi Drive provides the expected NAS services such as SMB and NFS access, RAID options, snapshots, encryption, share links, and multi user management, plus backup support that can include other UNAS targets, SMB destinations, and several cloud providers. The main compromises are the single 2.5GbE port that caps throughput and offers no redundancy, NVMe trays not being included despite the slots being present, and a USB C port that currently functions mostly for basic external storage rather than broader expansion, so it fits best when the goal is uncomplicated storage within a UniFi managed environment rather than a more flexible, performance oriented NAS platform.

The UniFi UNAS 4 uses a compact desktop chassis that differs from the more traditional box shaped NAS designs seen from many competing brands. The enclosure is relatively narrow and deep, giving it a vertical appearance that resembles some earlier consumer NAS designs. The casing itself is constructed from polycarbonate rather than metal, which keeps overall weight down to around 2.6 kg without drives installed. Ventilation is primarily handled through openings along the upper portion of the chassis, with airflow directed toward a rear mounted cooling fan.
At the front of the unit is a small 1.47 inch color LCM display that provides basic system information. This panel is not touch enabled but can show details such as drive activity, network activity, and general system status. It acts primarily as a quick visual reference rather than a full control interface. For most configuration and monitoring tasks, the system is intended to be managed through the UniFi Drive interface via a web browser or mobile application.
The primary storage configuration consists of 4 drive bays supporting either 3.5 inch or 2.5 inch SATA drives. Each drive uses an individual tray that slides into the chassis and clicks into place without requiring screws for 3.5 inch drives. The trays are ventilated and designed for relatively straightforward installation or replacement, although they are not lockable. Compared with earlier UniFi NAS designs that grouped multiple drives into a single tray, the use of separate trays simplifies drive access and improves hot swap usability.
In addition to the main hard drive bays, the system includes 2 M.2 NVMe slots intended for SSD caching. These slots are located in a separate compartment on the base of the device and can be accessed by removing a small cover using the included key. Once installed, these SSDs can be used to provide read and write caching to improve responsiveness when working with frequently accessed data. At the time of writing, these NVMe drives cannot be used as independent storage pools and are limited to caching roles.
One design choice that may affect installation is that the trays required to hold the NVMe SSDs are not included in the retail package. Instead, they must be purchased separately or obtained as part of pre populated SSD modules from Ubiquiti. While the M.2 slots themselves are built into the device, the lack of included trays adds an additional step and cost for users who intend to make use of SSD caching alongside the main hard drive storage.
Internally, the UniFi UNAS 4 is built around a quad core ARM Cortex A55 processor running at 1.7 GHz. This type of processor is commonly used in embedded networking hardware and lower power storage appliances, where efficiency and reliability are prioritized over raw processing performance. Ubiquiti has extensive experience deploying ARM architectures across its networking and infrastructure products, and the choice here aligns with the system’s intended role as a dedicated storage appliance rather than a general purpose server platform.
The system includes 4 GB of LPDDR4 memory, which is fixed and not user upgradeable. For the core functions the device is designed to handle, such as file transfers, backups, and storage management, this amount of memory is generally sufficient. However, the fixed memory configuration does place a ceiling on how much additional functionality the hardware could realistically support in the future, particularly if the software platform expands with additional services or heavier workloads.
From a power perspective, the system is designed to operate within a relatively modest power envelope. The maximum system power consumption is rated at 90 W, with a maximum drive power budget of 80 W. Power delivery is handled through PoE+++, allowing both data and power to be carried through the same Ethernet connection when used with compatible infrastructure. For deployments without PoE support, the device ships with a 90 W PoE+++ adapter, allowing it to be powered from a standard mains outlet while still maintaining the same connection layout.
The UniFi UNAS 4 keeps connectivity simple, with a single 2.5GbE RJ45 port handling both network data and PoE+++ power delivery. This allows the unit to be deployed with a single cable when used with compatible switches or injectors, which can reduce cable clutter and simplify placement compared with NAS systems that require separate power and network connections. The port supports 2.5G, 1G, 100M, and 10M link speeds, so it can operate in mixed networks even if 2.5GbE infrastructure is not available.
The main limitation is that there is only 1 network interface, with no secondary port for link aggregation, redundancy, or dedicated management traffic. In practical terms, this reduces options for failover and makes the network connection a single point of dependency. It also places a hard ceiling on throughput, which is relevant on a 4 bay system where aggregate drive performance can exceed what a single 2.5GbE link can sustain in some workloads.
For external expansion, the device includes a 5 Gbps USB C port intended for attaching external storage. In its current form, it functions primarily as a straightforward way to connect a USB drive for basic transfers rather than as a broader expansion interface. The hardware capability suggests potential for wider use cases, but the available functionality is mainly determined by what UniFi Drive supports at the software level.
The UNAS 4 runs UniFi Drive and is managed through the same UniFi style web interface used across the wider portfolio, with system status, storage, backups, and user access presented through a single dashboard. For typical NAS use, the core functions are in place: initializing drives, building RAID storage, creating shared and personal drives, enabling file services, and checking drive health information. The interface is mostly structured around completing common tasks quickly and keeping administration consistent with other UniFi products, rather than exposing a long list of granular configuration controls. That approach makes initial setup and day to day management relatively straightforward, but it also means experienced NAS users may notice limits in how far the system can be tuned.
|
|
File access is centered on SMB and NFS, with browser based file management available for basic upload, download, and folder navigation. The web file manager covers essential functions and includes share link creation plus thumbnail and preview handling, but it is not designed as a full productivity layer with collaborative editing or advanced file workflow tools. Client access is largely built around standard network shares and UniFi’s account-driven identity layer, and while the system can be deployed locally without relying on a UniFi account, the most integrated remote workflow is clearly designed around UniFi’s own UI and identity services rather than third party remote networking options.
|
|
Data protection features cover most of what is expected for a general purpose file NAS. UniFi Drive supports snapshots, encrypted storage, and configurable retention policies, which covers common rollback needs and basic ransomware recovery strategy when paired with sensible scheduling. Backup tooling is one of the stronger areas in terms of scope, supporting tasks to another UniFi NAS, to SMB targets, and to cloud services such as Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, and Wasabi. Time Machine support is also present for macOS environments, and Microsoft 365 backup is part of the broader UniFi Drive direction, even if the overall feature set remains more storage and protection focused than application focused.
|
|
The limitations are consistent with the UNAS 4’s role and its hardware profile. There is no iSCSI target support, which restricts certain virtualization, hypervisor, and block storage workflows, and there is no container or VM layer intended for running third party services directly on the device. NVMe support remains limited to SSD caching rather than separate pools, and on the UNAS 4 that caching is also constrained by the single 2.5GbE connection, which can cap how much of the cache benefit is visible over the network in sustained sequential transfers. More broadly, system level configuration remains relatively contained, with fewer advanced networking and scheduling controls than many established NAS platforms provide.
|
|
Client side tooling is also still relatively limited compared with ecosystems that offer a more developed sync, selective download, and offline pinning experience across desktop and mobile. UniFi Drive does provide client app support and identity driven access, but the overall workflow remains closer to traditional network share usage than to a full cloud drive style experience. As it stands, the software aligns with the UNAS 4’s positioning as a storage and backup appliance with a clean management layer, rather than a platform intended to replace a more feature dense NAS operating system.
|
|
In practical use, performance on the UNAS 4 is largely shaped by its single 2.5GbE connection. With mechanical drives, the system can deliver consistent transfer rates that sit within the expected ceiling of a 2.5GbE link, but it does not have the networking headroom to take full advantage of what a 4 drive array can potentially deliver under sustained sequential workloads. This is most noticeable when using higher capacity 7200 RPM drives, where the combined throughput of multiple disks can exceed the network limit even before SSD caching is factored in.
|
|
Testing with mixed file transfers showed typical throughput in the range of roughly 180 to 250 MB/s depending on file type and workload, with higher results generally observed once NVMe caching was enabled. A 50 GB Windows transfer completed at a pace that aligned with these figures, with sustained rates remaining stable rather than spiking briefly and then dropping sharply. The overall behaviour suggests that the device can maintain steady network limited transfers, but it is not designed to chase peak throughput beyond what 2.5GbE allows.
|
|
NVMe caching improved responsiveness and helped maintain higher sustained transfer speeds, particularly during repeated reads and writes where the cache could play an active role. However, the caching implementation is limited to acceleration rather than acting as a separate storage tier, and the benefit is workload dependent. Large sequential transfers still remain constrained by the network port, while smaller or more frequently accessed data sees more practical gains from the cache layer.
|
|
From an operational standpoint, power draw remained relatively modest for a 4 bay system. A baseline measurement with no drives installed was around 14.1 W. With 4 HDDs and 2 NVMe SSDs installed, idle power use was observed at around 46 W, rising to roughly 50 to 51 W under active read and write workloads with moderate CPU and memory utilization. The relatively small gap between idle and active indicates that drive idle draw forms a significant portion of the total consumption in typical day to day use.

The UniFi UNAS 4 is a compact 4 bay NAS that prioritizes straightforward storage deployment, particularly for users already running UniFi hardware and UniFi management. Its pricing, PoE+++ support with an included adapter, NVMe caching capability, and generally simple physical drive access make it a practical option for core NAS tasks such as shared folders, backups, and centralized file storage. The hardware choices are consistent with that goal, and the platform is best assessed as a storage appliance rather than a general purpose server. On the software side, UniFi Drive provides the expected baseline services for this category, including SMB and NFS file access, RAID options, snapshots, encrypted storage, share links, and multi user management. Backup support is broader than the basics, with options that can include remote UNAS targets, SMB destinations, and several mainstream cloud services, along with Time Machine support for macOS. Management is clearly aimed at keeping configuration simple through a unified interface, but it also remains more limited than mature NAS platforms in areas such as deeper system tuning, third party remote access alternatives, and broader application style features.
The trade offs are easy to identify. A single 2.5GbE port limits peak throughput and removes options such as link aggregation or network failover, which matters more on a 4 bay system than it would on a smaller unit. The NVMe slots are limited to caching rather than independent pools, and using them adds cost due to trays not being included. Cooling behaviour can become more noticeable if fan speed increases, and the USB C port currently operates mainly as an external drive attachment point rather than a broader expansion interface. Overall, the UNAS 4 makes the most sense when its role is kept narrow, and when UniFi Drive’s storage and backup feature set, alongside UniFi ecosystem integration, is a meaningful part of the purchase decision.
