UGREEN DXP480T NASync SSD NAS Review
What exactly IS the DXP480T? Ever since UGREEN launched their NASync range of NAS devices on Kickstarter, there has been a lot of interest in this computer accessories and peripheral company making its big move into Network Attached Storage. No doubt hoping to challenge this market’s leaders Synology and QNAP, UGREEN have revealed a 6 system series (the DXP range) and although the first 5 of them are interesting enough, it is the compact yet powerful NVMe Flash-equipped NASync DXP480T that has drawn many a hungry I.T user’s eye! Arriving with a 10 Core Intel i5 Processor, DDR5 memory, PCIe Gen 4 Architecture, 4x m.2 2280 NVMe SSD bays, 10GbE networking, Thunderbolt 4 ports and Wifi 6E connectivity – There is ALOT crammed into this tiny little box! Add to this the ‘still in development’ UGOS NAS software that is included with the system and the $479-519 price tag for early access on Kickstarter (going up to $799 RRP when it hits ACTUAL retail) and what you have here is a fantastic proposition for photo and video editors that are looking for a small footprint, low noise, but high-performance private server. But is it too good to be true? Is there too much hardware in there to stay cool? And why is a big brand like UGREEN turning to crowdfunding? Let’s discuss the DXP480T and whether it deserves your money and your data.

Ugreen DXP480T NAS Review – Quick Conclusion
There is ALOT of like her in the UGREEN DXP480T Flash NAS! Right now there is little to no alternative to this product in the market. Flash/SSD NAS has been around for a long time and even M.2 NVMe NAS systems have been cropping up in one form or another for 2+ years. But desktop and home-accessible M.2 NVMe Flash NAS solutions? Barely any. Notable alternatives such as the storage-rich Asustor Flashstor 6 / 12 Pro or the performance-rich QNAP TBS-464 or TBS-h574TX have been launched in the last 12 months, but the DXP480T is more powerful than the former and less expensive than the latter. However UGREEN and it’s DXP/NASync series are still very, VERY new in the market (green?) and alongside their NAS software being still a good distance away from fully stable, the choice to launch this new series of devices on crowdfunding is still a little puzzling for 12-14 year established brand in the tech sector. The system is fantastically compact, powerful for the scale, very rich in hardware features and all of this rollout out on a price tag at both early backer Kickstarter and eventual retail RRP that is highly challenging to beat!
But this is still a product that is not finished yet and therefore we need to keep that in mind! If this NAS an unfinished game, it is not ‘Cyberpunk’ or No Man Sky’ levels of incomplete – but it is still a good 20-30% unfinished in terms of features and optimization. I will be certainly keeping an eye on UGREEN as they progress, and hopefully they will challenge the status quo of Synology and QNAP right now, but we will have to wait and see. Bottom line, the DXP480T is 100% the BEST M.2 NVMe NAS system for it’s scale in terms of hardware, it’s just the rest of the software development going through the usual beta testing that is holding it back from greatness. Recent softening by UGREEN with regard to users installing 3rd party operating systems (TrueNAS, UnRAID, Open Media Vault, Proxmox hypervisor, etc) with regard to hardware warranty has definitely resolved/calmed the apprehension by many users though, so the beta software hurdle might not even be an issue for you. The crowdfunding still at has 30 days left (at the time of writing) and 9,800 backers pledging over $4,00,000 of funding seems to indicate this! But as always, this is crowdfunding and not traditional retail, so use caution! The DXP480T is a solid and unique system and I hope to talk even more about this and UGREEN spin-offs in future!
Ugreen DXP480T NAS Review – Retail Package
The retail kit for this system arrives impressively polished for a product still in its crowdfunding phase, featuring a well-decorated and well-presented retail package that efficiently packs a surprising amount of equipment into a modestly sized box.
Upon opening the stylish retail package, you’re welcomed by the system itself, encased in a protective matte plastic wrap. Remarkably compact for a four-bay (technically five) NAS system, it’s slightly larger than a mini PC, making it one of the smallest NAS systems reviewed on NAS compares.
The kit is comprehensive, excluding storage, including a gold-tipped Ethernet cable, thermal pads for M.2 NVMe SSD bays, extra screws, a setup manual, warranty information, and an external PSU.
Notably, the system comes with an official UGreen 140W PSU, reflecting the brand’s reputation for quality power supplies. The inclusion of first-party designed and branded components emphasizes the product’s proprietary nature, distinguishing it from rebranded hardware.
The entire retail kit’s presentation is thoroughly executed, showcasing a thoughtful design even in details like the instruction booklet—a feature many brands have phased out.
Ugreen DXP480T NAS Review – Design
At a casual glance, you might easily assume that the DXP480T is a mini PC masquerading as a NAS. Given the influx of SOC-powered mini PCs from Eastern brands at low prices, this assumption wouldn’t be far-fetched. However, the DXP480T’s design is meticulously tailored to NAS functionality, with internal components arranged to optimize heat dissipation across its M.2 NVMe slots. This compact unit measures just 17.9cm x 14.2cm x 5.2cm, yet manages to house four M.2 2280 slots and an additional internal 2242 M.2 slot for the UGreen OS, making it one of the smallest NAS systems reviewed here on NAScompares and around half a kilo in weight!
Despite its compact size, the DXP480T does not support hot swapping due to its closed physical enclosure and the nature of M.2 drives, though E1.S drives are starting to challenge this norm. The chassis design is a balanced act of 50% active airflow and 50% heat dissipation, featuring plastic outer edges and a top composed of multiple heat dissipation panels connected to the internal hardware, alongside a large heatsink base with two built-in laptop-scale fans. This design emphasizes cleanliness and efficiency, given its storage capacity.
UGreen’s branding is prominent throughout, establishing a distinctive ‘house style’ for the NASync/DXP series right out of the gate. The system’s dimensions (18cm wide, 14cm deep, and 5.5cm tall, including rubber feet) enhance its appeal, offering a streamlined aesthetic without sacrificing functionality.
The fan-assisted panel, secured by two screws, hinges off to reveal the NVMe storage and the intricately designed heat dissipation panel surrounding it. Despite the limited physical space, UGreen has ingeniously incorporated ventilation from nearly every angle, maximizing passive airflow through mesh-covered vents on four of the system’s six sides.
This setup exposes four M.2 SSD slots, distinguished by build quality and clarity in design. However, the use of external face panels for active cooling restricts the use of SSDs with their own heatsinks. UGreen includes high-quality heat pads that align perfectly with SSD chips, compensating for this limitation.
Internally, the slots are divided into two speeds, likely due to the processor’s PCI lane availability, offering Gen 4 x 4 for the first two slots and PCIe Gen 3 x 2 for the remaining two. This strategic decision, driven by necessity, positions the DXP480T favorably against competitors, even if it means accepting some compromises in SSD speeds.
The minimalistic design extends to the system’s front, featuring only a single LED for power, omitting front-mounted USB ports for local backups. This choice, likely a trade-off for internal design efficiency, may disappoint some users looking for more convenient connectivity options.
In summary, the DXP480T’s design impresses with its compact form factor, efficient heat management, and thoughtful branding. While not without its limitations, particularly in external connectivity, UGreen’s meticulous attention to detail positions this NAS as a compelling option for users prioritizing sleek design and effective thermal management.
Ugreen DXP480T NAS Review – Ports and Connections
As previously mentioned, the DXP480T’s ports and connectivity are located at the system’s rear, which results in a somewhat crowded arrangement and necessitates a few compromises.
One significant compromise concerning the device’s ports is its network connectivity. The system features a default 10GbE over a copper RJ45 connection, offering potential bandwidth of up to 1000 megabytes per second. This feature stands out, especially when considering the device’s competitive pricing compared to other NAS devices released in the last two years. However, the downside is that this is the sole physical network port, limiting options for failover or assigning service priorities to different IPs and devices.
The system compensates for this single network port to some extent with wireless connectivity.
An internal M.2 Wi-Fi card connector houses a Wi-Fi 6E network adapter and two antennas, supporting both host and client interfaces.
However, the current beta version of UGreen’s UGOS NAS software does not stably support this feature, and full development completion is still pending.
Additionally, the DXP480T offers Thunderbolt 4 connectivity via two USB-C connections. While Thunderbolt-enabled NAS devices are becoming popular in post-production environments, the DXP480T’s Thunderbolt ports are limited to host use, not supporting direct connections to Mac or Windows devices as clients. UGreen is exploring options to enable two-way communication for these ports. The device also includes USB 3 and USB 2 connections for storage and peripherals, and while direct host-client interfacing over USB is not supported, these connections add to the system’s versatility. However, the lack of a front-mounted USB port for easy local backups is a notable omission.
There is also an HDMI output, however at this time it can only be used for multimedia via the UGOS and is actioned via the mobile application (with doubles as a remote control). Unfortunately, this is not possible via the desktop/browser GUI and also HDMI access as a parallel GUI (either via an app in the docker/container app, a 3rd party media app like Plex/Emby/Jellyfin or an official HDMI GUI Portal that is comparable to HD Station from QNAP or Asustor Portal)
Despite these limitations, the inclusion of 10 GBE and basic Thunderbolt connectivity in such a compact NAS device, at a competitive price point, is commendable. However, the potential long-term system temperature remains a concern.
Ugreen DXP480T NAS Review – Internal Hardware
When it comes to any kind of NAS system that focuses on SSD media, the internal hardware and layout of the system are paramount. SSD media, when overheated, will inevitably throttle, affecting both its performance and that of the surrounding system. Essentially, heat is the Achilles’ heel of flash SSD systems, and given the DXP480T’s compact size, significant effort will need to be made to manage this.
Equipped with a 10-core i5 processor, 8GB of DDR5 memory, ample storage bays, a dedicated OS SSD, a Wi-Fi card, and a 10G controller, it’s a challenge to fit all this into such a small enclosure. Initially, removing two screws around the storage media bays reveals a plastic layer.
Within, we find each of the individual 2280 M.2 NVMe slots. We also discover the SODIMM DDR5 memory slots, one of which is populated by a Samsung DDR5 memory module. Although the system doesn’t support ECC memory, it benefits from the native DDR5 support for on-die error correction. Nonetheless, many storage enthusiasts will likely be disappointed by the lack of ECC support in a flash server system.
As previously mentioned, the system includes a Wi-Fi 6 Intel wireless adapter connected to two internal antennas that encircle the system. It’s a tidy setup, and barring an upgrade to Wi-Fi 7 in the future, there’s little need for changes. It’s debatable how many users will utilize the 1.2Gbps connectivity offered by Wi-Fi 6E; though technically faster than traditional gigabit LAN, effective use requires close proximity. Despite this, it offers a form of failover for this system with a single physical ethernet connection.
The system also arrives with the UGreen NAS software pre-installed on a 2242 Phison E13 controller SSD, set in a Gen 3 x4 slot. Choosing to install the OS on a dedicated SSD, rather than through an eMMC or USB drive, will please some and annoy others. Typically, NAS brands use a bootloader on a small internal drive to install the OS on the main storage array, affecting the system’s performance based on the internal storage media used. Opting to install the OS directly onto an SSD ensures that system services and software run independently, not impacting the performance of the storage media, allowing for operation with new disks if necessary. However, this also means the OS drive lacks backup or redundancy, rendering the system inoperable should the drive fail, potentially damaging the storage media during intense operations. There are pros and cons, but overall, it seems preferable for the system software and services to reside on their dedicated SSD or partition.
Removing additional screws unveils the system’s core. It’s astonishing how much is packed into such a compact enclosure! The heart of the DXP480T features a custom micro-ITX board, housing an Intel i5 10-core processor (2p + 8e), integrated graphics, 20 PCIe lanes, and a maximum 55W TDP. Despite its compact SOC form, this 12th generation Intel i5 processor offers substantial power, benchmarking well against the N100 and Pentium 8505 models in other UGreen NAS models.
Testing this processor, especially in this early crowdfunding prototype, presents challenges. The DXP480T, like the rest of the UGreen NAS line-up, doesn’t officially support third-party OS installation without voiding the warranty. Consequently, we’re limited in our ability to benchmark using third-party OSs or reference previous benchmarks for similar architectures. The UGreen NAS’s operating system, still in beta, requires further optimization to fully showcase what the hardware can achieve.
This processor is well-equipped with sufficient PCIe lanes to manage the four M.2 NVMe SSDs, offering respectable speeds through SSH. The main concern with this processor selection is the lack of ECC memory support, crucial for high-speed flash systems to minimize bit errors during intensive operations.
Although SOC processors that support ECC are rare, especially from Intel, using one for this system and potentially for the DXP8800 Pro could significantly impact the price and development timeline. Nevertheless, this CPU is arguably the best choice for such a compact system in 2024, balancing power efficiency, heat management, and performance capabilities.
UGREEN DXP480T NASync NAS Tests
The Noise level of the system when in operation is very low and is genuinely only noticeable during busy periods when the twin base mini laptop style fans kick in. Here are the dB levels of the system when in idle/standby:

UGREEN DXP480T ACTIVE USE / FULL FAN NOISE:
The construction of the DXP480T flash NAS deserves high praise. Rather than modifying a mini PC case, UGreen designed a compact flash system from scratch, demonstrating considerable care and attention to component placement. The hardware is undoubtedly attractive, further emphasized by our deep dive into this and the DXP4800 Plus models. Yet, the performance and capabilities of the software remain to be seen.
Ugreen DXP480T NAS Review – Performance & Software
The performance of the UGREEN DXP480T is something of a mixed bag. Clearly, compromises have needed to balance between the hardware resources on offer here and to keep the system’s smaller scale. For example, the 2x Gen 4×4 slots are only possible thanks to the scaling back of the 2x Gen 3×2 slots. They COULD have scaled all the slots (with a decent enough PCIe switch/controller) to all be 3×2 via bifurcation, but I think I prefer the 2 higher-performing slots at least giving me the chance to hit 5-7GB/s. I do wonder what they mean for those who plan on spreading a RAID 5 on the 4 M.2 NVMes – as this effectively means you have 2 drives with more bandwidth and irregular write across the 4 disks potentially (though realistically, it will just end up capping at the speed of drives 3 and 4). The performance of the DXP480T Flash system can be broken down into 2 main areas. Internal Performance and External Performance.
The Storage manager of UGOS features it’s on benchmarking tools that can be used per drive. The initial performance when I was using an early version of the software was severely unoptimized, but regular updates for the UGOS beta has rolled out almost weekly and with each, there has definitely been improvements in the system responsiveness and the performance of the drives. At the most recent test of the software, the Gen 4×4 slots of the system (populated with Phison E18 4×4 M.2 NVMes from Seagate Firecude 530 and Addlink A95) were hitting 5,100-5,500MB/s (5.5GB/s) performance. This is still around 1000MB/s less than what these drives are capable of (factoring in the mobile SoC processor and 8GB RAM), but as the software and services are still in beta, this performance might continue to improve throughout development. Then I ran the same test on the PCIe Gen 3×2 slots on the DXP480T. These ports were populated by Teamgroup T-Force Gen 3×4 SSDs, which have a reported 3,100MB/s performance when used in a x4 slot. However, as slot 3 and 4 of the DXP480T are Gen 3×2, I wondered how this would shake out. I was pleased to see a speed of 1.5-1.8GB/S – exactly what I wanted to see!
Then I accessed the system via SSH and used putty to directly benchmark the SSDs over cl. There was definitely some internal caching taking place in the early tests, however, the performance was still averaging around 5.5-6GB/s, which was very pleasing.
However, in order to ascertain if the SSDs in slots 1 and 2 were sharing any controller/switch (maybe even a larger lane being separated into the other 2 slots) I actioned data transfer between SSD 1 and SSD 2. The speed unsurprisingly halved, but was still much, much between the 1-1.5GB/s I encountered when performing this test 2 weeks and 2 firmware updates ago! Now I was hitting 2.5-3GB/s. For internal bandwidth saturation internally on this scale, that is still pretty good.
Then I performed numerous Windows 10GbE transfer tests. The Windows transfer of 20GB of data hit a clean 1,000MB/s saturation when I was using synthetic testing, but traditional transfers on Read activity (to my Windows 10, Gen 4×4 SSD OS Client) peaked at 550MB/s, but the Write was a little under 500MB/s. This decreased fairly rapidly over sustained performance as very clear oversaturation took hold. Upon raising this with the brand in advance of this review for comment, UGREEN told me that SMB performance and transfers are still undergoing optimization. I hope this is the case!
This continued to be the performance mark when I ran an AJA benchmark.
Crystal disk was run twice (using 2 different file size scales, 64MB and 1GB) and once again Read largely saturated the connection, whilst Write was still only 50-65% saturating the available 10GbE bandwidth.
Then I ended on an ATTO Diskbenchmark test that was..frankly.. wild! It was a fairly consistent 700-800MB/s on average, but the perpetual and sustained performance of ATTO benchmarks to the system definitely revealed some of the areas where optimization is still needed and the system was quickly oversaturated (fans ramping up quickly, the memory use very high for the comparatively simple task).
There is definitely some good performance potential here in the DXP480T – as long as UGREEN continue to improve and optimize. This is a prototype review unit (i.e a review unit provided prior to crowdfunding) and certainly feels that way – but numerous software patches that arrived BEFORE the crowdfunding arrived that improved things granularly and I have no reason to believe that this will not continue from now till when/if the system begins fulfilment at crowdfunding and eventual full retail. Watch the video below to see the tests in full (it skips ahead directly to the testing):

At the time of writing, the UGREEN NAS software is still in beta, with the mobile application is live now. Reviewing the software included with the DXP480T —as a final product— feels somewhat premature. The NASsync software beta reveals many baseline functions and long-term plans, which you can watch in the video version of the UGREEN UGOS NAS Software Beta Review in the video below:
You can read the MASSIVE Software review (covering the Desktop and Mobile experience) HERE on the NASCompares Review Article.
Regarding Power Consumption Tests of the UGREEN DXP480T NAS
NOTE – Power consumption tests were performed on the DXP480T during an earlier software beta revision. However, 3 further software and system service updates have been issued since these power consumption tests were performed 3 weeks ago and UGREEN (and a fellow YouTube Reviewer) have stated that this has improved the power efficiency of the system. Therefore in the interests of fairness (as the performance testing was performed on this later software revision (v1.0.0.0334), I have withdrawn my power test result and will be retesting soon and presenting it here + in a later video, as time allows.
The TL;DR on the UGREEN NAS software
The software is on track to become a smooth and user-friendly experience, comparable to giants like Synology and QNAP, especially in terms of the web browser experience. Unlike opting for the complexity of TrueNAS or the streamlined, container-focused UI of UnRAID, the UGREEN NAS software is more akin to Synology DSM. The foundation is clearly laid out for expansion in terms of features and tools for the user’s disposal. However, there are notable absences of baseline applications such as container or virtual machine support, and a multi-tiered backup solution within the web GUI (though the UGREEN NAS mobile and desktop clients are in development, expected to preview in March). Basic services for file management, shares, user account control, and an app center—soon to be linked to a repository—are all user-friendly but present some inconsistencies, likely due to its beta status and ongoing development. The physical product may be closer to final development, but the software needs more time for optimization. SMB services were less consistent than desired, and settings changes sometimes didn’t save or recall correctly. This is common for beta software finding its footing, yet it’s important to note that the hardware feels more refined than the software at this stage, months before user delivery. In brief:
What I liked:
- Intuitive UI with services located logically and responsive controls.
- The mobile application for iOS and Android is one of the best I have ever used in NAS!
- Baseline services such as network interface management, user account control, firewall handling, and SSH interface control are all present.
- A clearly defined app center awaiting connection to an online repository.
- Helpful tips and guidance are available on most pages, aiding new users.
- Support for modern services like SMB3 multi-channel and domain services in the beta.
- Clear account and resource management accessible from the desktop, likely appealing to most users.
- The inclusion of a remote access relay service and UGREEN account creation from day one, simplifying remote access for new users with built-in firewall and domain tools.
- UPDATE 5/4/24 – The HDMI output is now full controllable via the mobile application and is intuitive
- UPDATE 5/4/24 – A Docker application has now been added with access to numerous repository options!
- UPDATE 5/4/24 – SSH is now disabled by default
What I disliked:
- Absence of two-factor authentication in the software.
- Lack of virtualization applications at this stage.
- Sporadic SMB performance.
- The Security Advisor tool is only suitable for Antivirus and Anti-Maleware protection, not to scan the system for security weaknesses and advisory actions
- The HDMI output cannot be used by the desktop/browser user to the same extent as the mobile application + cannot be used by container tools (Plex, Home Automation, etc)
- In-progress language integration, leading to occasional default displays in Chinese or error messages in Chinese despite English settings.
Improvements needed:
- Expansion of app integration and desktop client tools for easier system-client bridging.
- Introduction of a default application for device discovery on the local network, a basic service offered by many NAS brands.
- More information on UGREEN account and remote access security.
Acknowledging this is a beta, it’s fair to reserve full judgment until the software fully rolls out. As it stands, this beta is promising yet lacks some established NAS software fundamentals. Hopefully, we’ll see significant advancements as the release approaches.
