UGREEN DXP4800 PRO Review – Step Up, or Side Step?

The UGREEN NASync DXP4800 Pro is a 4 bay desktop NAS that builds on the existing DXP4800 Plus rather than replacing it outright. From a hardware and design perspective, the system remains very familiar, but it introduces a newer Intel Core i3 1315U processor and increases the maximum supported memory to 96GB. Networking remains unchanged, with both 10GbE and 2.5GbE available, and the unit continues to support dual NVMe SSDs for caching or dedicated storage pools. These updates position the DXP4800 Pro as a slightly more capable option for users who want additional CPU headroom without moving into a larger and more expensive multi bay platform.

At launch, the DXP4800 Pro is listed as a diskless system at $699.99 and is aimed at home power users, creators and small offices looking for a turnkey NAS that can handle container workloads, virtual machines and media workloads more comfortably than entry level models. While the hardware changes are relatively contained, they directly affect performance scaling and long term flexibility. This makes the DXP4800 Pro less of a generational leap and more of a mid cycle refinement, intended for buyers who want modest improvements in processing capability and memory capacity while keeping the same overall form factor and feature set.

UGREEN DXP4800 PRO Review – Quick Conclusion

The UGREEN NASync DXP4800 Pro is a 4 bay NAS that focuses on incremental improvement rather than major change, pairing an Intel Core i3 1315U with up to 96GB of DDR5 memory, dual NVMe slots and 10GbE plus 2.5GbE networking in the same compact metal chassis as the DXP4800 Plus. It delivers solid real world performance for file transfers, SSD caching, media workloads and container use, with good NVMe throughput and reliable 10GbE performance, but power consumption is noticeably higher than lower power NAS alternatives and internal SSD to SSD transfers do not always reach their theoretical limits. Build quality and storage flexibility are strong, noise levels are generally reasonable but rise under heavy load, and thermals remain under control despite limited underside clearance. UGOS Pro offers a broad feature set with Docker, virtualization, snapshots and AI assisted photo tools, though its security scanning remains focused on malware rather than wider system hardening and application availability is still maturing. Overall, the DXP4800 Pro is a capable and well balanced mid tier NAS best suited to users who want extra CPU headroom and long term flexibility, but it does not represent a compelling upgrade for existing DXP4800 Plus owners and its value depends largely on how much the added performance will actually be used.

UGREEN DXP4800 PRO Review – Design & Storage

The DXP4800 Pro continues to use the same compact metal chassis as the DXP4800 Plus, with no structural redesign to the enclosure itself. The overall dimensions and layout remain unchanged, which makes it easy to place alongside other desktop NAS systems in this class. While the external appearance is largely identical, the surface finish feels slightly different to the touch compared with the earlier model. This change does not affect durability or rigidity, but it does subtly distinguish the Pro from the Plus when handled directly. The metal construction also plays a functional role by assisting with passive heat dissipation across the enclosure.

On the front of the unit, four SATA drive bays are arranged vertically and support both 2.5 inch and 3.5 inch drives. The trays are tool free and lockable, with keys included, which provides a basic level of physical drive security.

Each bay connects to a shared backplane that feeds into an ASMedia 1164 SATA controller running over a PCIe Gen3 x2 link. This controller configuration is typical for a 4 bay NAS and provides adequate bandwidth for RAID 5 and RAID 6 arrays without becoming an immediate bottleneck under normal workloads.

Additional storage options are located on the underside of the chassis. Removing a small access panel reveals two M.2 NVMe slots along with two DDR5 SODIMM memory slots. This placement keeps the top and sides of the enclosure clean but requires the system to be powered down and removed from its location for upgrades. The two user accessible NVMe slots operate at PCIe Gen4 x4 speeds and can be used for SSD caching or for creating dedicated SSD storage pools, depending on workload requirements.

Thermal handling for the NVMe drives is addressed through the use of thick thermal pads that make direct contact with the metal base panel. Once installed, the base of the chassis effectively acts as a large passive heat spreader. Clearance between the bottom of the NAS and the desk surface is limited, which restricts airflow underneath the unit. However, during typical usage this design appears sufficient to keep NVMe temperatures within reasonable operating ranges, particularly when combined with the system’s active rear fan.

From a storage flexibility standpoint, the DXP4800 Pro offers a conventional but well rounded setup. Users can combine large capacity SATA drives with high speed NVMe SSDs, configure multiple RAID types, or separate workloads across different storage pools. While there is no support for external expansion units or PCIe add in cards, the internal layout covers the needs of most home and small office users looking for a balance between capacity, performance and simplicity.

UGREEN DXP4800 PRO Review – Internal Hardware

At the core of the DXP4800 Pro is the Intel Core i3 1315U, a 13th generation processor that replaces the Pentium Gold used in the DXP4800 Plus. This CPU brings a higher core and thread count, along with slightly higher boost frequencies and improved integrated graphics capability. In practical terms, this provides more headroom for parallel workloads such as Docker containers, background indexing tasks and light virtual machine use. While it is still a mobile class processor, it represents a measurable step up in sustained performance compared with the previous model.

The system ships with 8GB of DDR5 memory running at 5600MHz and supports expansion up to 96GB across two SODIMM slots. This increased memory ceiling is one of the more meaningful hardware changes, particularly for users running multiple services simultaneously or experimenting with virtualization. ODECC support is listed, although this remains dependent on compatible memory modules. Accessing the memory slots requires removing the base panel, which is straightforward but not tool free.

Internally, the DXP4800 Pro also includes a dedicated 128GB SSD used as the system drive for UGOS Pro. This drive operates independently of the two user accessible NVMe slots and ensures the operating system does not consume space from the main storage pools. The presence of a separate system disk also allows users to repurpose the NAS with alternative operating systems if desired, without interfering with the primary storage configuration or voiding the hardware warranty.

UGREEN DXP4800 PRO Review – Ports and Connections

The DXP4800 Pro offers the same port layout as the DXP4800 Plus, with no changes to the overall external connectivity. On the networking side, it includes both a 2.5GbE port and a 10GbE port on the rear of the unit. This dual network setup allows the system to integrate easily into standard home or office networks while also supporting higher bandwidth workflows where compatible switches and clients are available. Link aggregation is not required to access higher speeds, as the 10GbE port operates independently.

USB connectivity is split between the front and rear panels. On the front, there is one USB C and one USB A port, both operating at up to 10Gbps. These are suited for fast external storage, temporary backups or quick data transfers without needing to access the rear of the system. The rear panel includes one USB A port running at 5Gbps, along with two USB 2.0 ports intended for lower bandwidth peripherals such as UPS connections or input devices.

Additional I O options include an SD 3.0 card reader on the front panel and an HDMI output on the rear. The SD slot is primarily aimed at photographers and videographers who regularly offload media directly to the NAS, while the HDMI port supports local display output at up to 4K resolution. Together, these ports allow the DXP4800 Pro to function not only as a network storage device but also as a basic local media or management system when connected directly to a display.

UGREEN DXP4800 PRO Review – Noise, Heat, Power and Performance Tests

In network file transfers using four SATA hard drives configured in RAID 5, the DXP4800 Pro delivers performance in line with expectations for a 4 bay NAS equipped with 10GbE. Sequential read speeds during testing typically fell in the 450 to 500MB/s range, while write speeds were closer to 300 to 350MB/s. These figures reflect the limits of mechanical drives rather than any immediate system bottleneck, and represent a noticeable uplift compared with single drive performance when accessed over a high speed network connection.

NVMe performance is stronger, particularly when the two user accessible M.2 slots are configured as an SSD storage pool. Synthetic benchmarks conducted within the system reported read speeds in the 5.5 to 6GB/s range, while real world transfers over a 10GbE connection sustained approximately 660 to 680MB/s when copying large media files.

These results are consistent with the constraints of the network interface and show that the NVMe subsystem is not the limiting factor during external transfers.

1GB x 100 – SSH Read/Write Test over SSH – SSD Bay #1 (Gen 3×4 Slot)

1GB x 100 – SSH Read/Write Test over SSH – SSD Bay #2 (Gen 4×4 Slot)

Internal SSD testing via SSH revealed some variation depending on which drives were involved. The system SSD, operating over PCIe Gen3 x4, delivered around 3.1GB/s read and 2.4GB/s write in repeated tests.

Transfers between the two PCIe Gen4 NVMe drives reached higher raw throughput in isolation, but inter SSD transfers were lower than expected (AROUND 1-2 to 1.5Gb/s, suggesting that some operations may still route through system level processes rather than achieving full peer to peer speeds.

Power consumption is higher than that of entry level NAS models using low power CPUs. With four hard drives installed and both network ports connected, idle power draw measured around 28W. Under moderate load with active disks and light CPU usage, consumption increased to approximately 58 to 59W. At sustained full load, including CPU intensive tasks, active hard drives, NVMe access and network activity, power draw peaked in the low to mid 80W range. Noise levels remained modest at idle, but increased noticeably under heavy drive or cooling loads, particularly when the fan profile was set to prioritize cooling over acoustics.

During extended testing, the DXP4800 Pro maintained generally stable operating temperatures across the chassis and internal components, even under mixed workloads. After a 24 hour period with intermittent access and background activity, external surface temperatures measured in the mid to high 30°C range across most of the enclosure, with the front drive area and drive bays reaching the low 40°C range. The rear fan area and network ports remained cooler, typically in the high 30°C range. Particular attention was paid to the underside of the chassis, where the NVMe SSDs are thermally coupled to the metal base panel using thick thermal pads. Despite the relatively low clearance between the NAS and the desk surface, temperatures at the base remained around 34 to 35°C, indicating that heat dissipation through the chassis was effective. Overall, thermal behavior was well controlled for a compact metal 4 bay NAS, with no signs of excessive heat buildup during sustained operation.

Multimedia testing with Jellyfin showed that the DXP4800 Pro handles both playback and transcoding tasks efficiently for a system in this class. When playing high bitrate 4K HEVC content with hardware transcoding enabled, GPU utilization remained low, typically in the mid single digit percentage range, indicating effective use of Intel Quick Sync. Scaling up to 8K content, hardware transcoding continued to perform reliably, with GPU usage generally staying below the low teens and CPU utilization remaining modest.

Native playback of multiple 8K files without transcoding placed limited strain on the system, while simultaneous transcoding of several 8K streams pushed CPU usage higher but still within manageable limits. Overall, Jellyfin performance on the DXP4800 Pro demonstrates that the upgraded CPU and integrated graphics provide sufficient headroom for demanding media workloads, particularly when hardware acceleration is used, without causing system instability or excessive resource contention.

UGREEN DXP4800 PRO Review – Software and Services

The DXP4800 Pro runs UGREEN’s UGOS Pro operating system, which is accessed through a web browser, desktop client or mobile app. Initial setup is straightforward, with the desktop and mobile applications able to automatically detect the NAS on the local network. Most day to day management tasks are handled through a centralized web interface that groups storage, users, services and security settings in a way that is generally easy to navigate, even when multiple features are enabled at the same time.

User and security management are handled through the control panel, where password policies, account permissions and two factor authentication can be configured. The system supports individual users and groups, allowing access rights to be defined at both the folder and application level.

Basic security tools such as IP blocking rules and login attempt limits are included, although the built in security scanning focuses primarily on malware detection rather than broader configuration audits, such as identifying weak passwords or exposed services.

Storage and backup functionality is spread across several integrated tools. Users can create and manage RAID arrays, SSD caches or NVMe storage pools directly from the storage manager. Both EXT4 and BTRFS are supported, with BTRFS enabling snapshot based protection and file versioning. Backup options include local backups, synchronization between folders, backups to other NAS systems and support for iSCSI targets, which may be of interest to users running virtual machines or editing workloads from external systems.

Application support covers a range of common NAS use cases, including Docker containers, a built in virtual machine manager and a growing selection of multimedia tools. Photo management includes AI assisted features such as face recognition, object detection and duplicate filtering, all of which can be enabled or restricted on a per folder basis.

Video playback can be handled through the built in media tools or via third party applications such as Jellyfin, which supports hardware accelerated transcoding. While the platform continues to evolve, the software experience on the DXP4800 Pro is largely defined by the same strengths and limitations seen across the wider UGREEN NAS lineup.

UGREEN DXP4800 PRO vs DXP4800 PLUS – What Is The Difference?

The primary difference between the DXP4800 Pro and the DXP4800 Plus is the processor. The Plus model uses the Intel Pentium Gold 8505, a 12th generation x86 CPU with 5 cores and 6 threads that operates at a variable clock speed and delivers moderate performance for general NAS tasks. The Pro upgrades this to the Intel Core i3 1315U, a 13th generation processor with 6 cores and 8 threads that generally offers higher base and boost clock speeds. In addition to more cores and threads, the i3 benefits from a broader instruction set and enhanced power management, allowing it to sustain higher performance under load without excessive thermal or power draw penalties.

While both CPUs are built on Intel’s “Intel 7” process and share similar TDP behaviour, the Core i3 has a higher turbo frequency ceiling and stronger integrated graphics. This translates to improved performance in parallel workloads, multimedia tasks and certain GPU assisted processes. The integrated graphics in the i3 are also more capable than those in the Pentium Gold, which can assist in hardware accelerated transcoding and UI responsiveness, though neither CPU is designed for heavy graphical workloads. In practical use, the i3’s combination of higher clocks, additional threads and more robust graphics support results in more headroom for Docker, indexing, virtual machines or sustained multi service usage than the Pentium Gold.

Memory is the second meaningful distinction between the two systems. Both ship with 8GB of DDR5 RAM, support ODECC and use a dual SODIMM layout, but the maximum supported capacity differs. The DXP4800 Plus supports up to 64GB, while the DXP4800 Pro increases this limit to 96GB, allowing more room for virtual machines, larger container stacks or memory intensive applications over time. Outside of CPU and memory, the two models are effectively identical. They share the same chassis, 4 bay SATA layout, dual M.2 NVMe slots, dedicated 128GB system SSD, identical RAID options, dual Ethernet ports (10GbE plus 2.5GbE), front and rear USB connectivity, SD 3.0 card reader and an HDMI output. Power consumption figures and physical dimensions are also the same on paper. As a result, the Pro model is best viewed as a performance focused refinement rather than a broader feature upgrade, with its value tied almost entirely to the stronger CPU performance and higher memory ceiling rather than any changes to storage, networking or overall platform design.

UGREEN DXP4800 PRO Review – Verdict & Conclusions

The UGREEN NASync DXP4800 Pro positions itself as a careful update to the existing DXP4800 Plus rather than a clear generational replacement. The transition to the Intel Core i3 1315U brings tangible improvements in CPU capability, particularly for users running multiple background services, Docker containers or occasional virtual machines. The higher memory ceiling also improves long term flexibility, especially for workloads that scale gradually over time. At the same time, the unchanged chassis, storage layout and connectivity mean that day to day usage will feel very familiar to anyone who has used earlier DXP models. From a broader perspective, the DXP4800 Pro sits in a narrow space within UGREEN’s lineup.

It offers more processing headroom than the Plus model, but it does not fundamentally change what the platform can do. Network performance, storage expandability and external I O remain the same, and the gains are most noticeable under heavier or more sustained workloads rather than light file serving. This makes the system better suited to users who already know they will push the CPU or memory harder, rather than those simply looking for basic network storage. For new buyers, the DXP4800 Pro can be a sensible choice if the price difference over the DXP4800 Plus is reasonable and the additional CPU capacity is likely to be used. For existing Plus owners, the case for upgrading is limited unless current workloads are already CPU constrained. Overall, the DXP4800 Pro is a competent and well executed 4 bay NAS that emphasizes incremental improvement over innovation. Its appeal lies in refinement and stability rather than standout features, and its value ultimately depends on whether those refinements align with the intended use case.

Best NAS You Can Buy Right Now for Under $499 at the end of 2025

By late 2025, the under 499 dollar NAS segment has become far more crowded, with multiple vendors offering systems that combine capable hardware, established operating systems, and multi bay storage at a relatively accessible price. Home users, prosumers, and small workgroups now have access to devices that can centralise files, manage routine backups, and handle local media streaming at performance levels that were previously limited to higher priced units. The range of available designs has also grown, with everything from compact solid state based units to entry level rackmount models appearing in this category. This guide looks at five (technically 6!) turnkey NAS platforms that can be purchased for 499 dollars or less. Each one focuses on a different balance of features, whether that is throughput, virtualisation, containers, or ease of use, yet all provide a practical path toward reliable self hosted storage without pushing the budget too far.

Important Disclaimer and Notes Before You Buy

Every NAS in this bracket is sold without drives, so users must provide their own storage, whether that is 3.5 inch HDDs, 2.5 inch SSDs, or M.2 NVMe modules for all flash builds. This directly influences total cost, particularly for NVMe based systems. Some models include small flash or eMMC for the operating system, but these are not suitable for general data storage. Buyers should account for drive costs, planned RAID layouts, and any needed accessories such as cables, heatsinks, or extra cooling. Software support also varies, with many devices using vendor platforms like DSM, TOS, or UGOS, while others permit alternatives such as TrueNAS or Unraid without affecting hardware support. Systems with less mature software may require more setup work for Plex, Docker, or SMB services, making these NAS units better suited to users who are comfortable handling basic network configuration or are willing to learn more advanced features over time.

UnifyDrive UT2 Mobile NAS Drive

$399 –RK3588 8GB, LPDDR4X 1, 2.5GbE, 6TOPS NPU, 4K HDMI 2.1, WiFi 6 + AP Mode, DAS Mode, 2 Hour Mobile Battery – BUY HERE ( Get a further 5% OFF with this code: NASCOMPARES )

The UnifyDrive UT2 Portable NAS is now a fully released product rather than a crowdfunding prototype, and its design reflects a complete, ready to ship package. The system is compact, roughly the size of a thick smartphone, and weighs around 350g with its protective rubber sleeve. It includes a 32GB eMMC module for the operating system, two M.2 NVMe SSD slots for storage, active cooling, WiFi 6, Bluetooth, a 2.5GbE port, HDMI output, and an internal battery that provides around 30 to 60 minutes of runtime and basic UPS functionality. The retail kit includes multiple USB cables, a power adapter, a remote control for HDMI use, SD and CFe card backup support, and printed quick start materials. Although the fan is audible under load, overall noise levels remain low for a compact ARM based system, and the design allows users to run the NAS handheld, placed on a desk, or carried in a bag without difficulty.

Connectivity is one of the UT2’s strongest aspects. Alongside its dual 5Gb USB ports, users can switch the device between network attached storage mode and direct attached storage mode. The two SD card slots support automated or one touch backups, and the 2.5GbE port gives the unit higher wired throughput than many portable or entry level NAS devices. HDMI output supports up to 4K60 and 8K playback, and media can be controlled either through the mobile application or the included remote. Internally, the UT2 uses a Rockchip RK3588C CPU with ARM Mali G610 graphics and 8GB of LPDDR4X memory. The two NVMe slots appear to operate at PCIe Gen 3 x1 speeds, which is adequate for saturating the wired and wireless interfaces. The memory is soldered and non upgradable, so users who intend to run more demanding workloads will need to account for that limit. Wireless access works through both client mode and the device’s own WiFi access point, enabling file sharing or backup without a pre existing network.

Software management centres on the UnifyDrive mobile application, which has expanded since the product first appeared and now includes RAID pool creation, the selective UDR RAID mode, SMB and FTP services, DLNA media streaming, direct HDMI output control, cloud sync, real time sharing, and device monitoring. Setup can be completed over LAN, WiFi, or Bluetooth, and firmware is updated over the air. The app provides tools for backups, encrypted folders, AI driven photo recognition, scheduled power controls, and general file management. Some advanced features such as additional downloader tools and container support remain under development, but the current software offers more control than most mobile focused NAS interfaces. Remote access is available through an integrated relay service, though support for third party VPN solutions is not yet included. With its combination of portability, NVMe storage, multi mode connectivity, and a growing software stack, the UT2 occupies a niche for users who want a personal cloud device that can be carried between locations while still supporting standard NAS workflows at its 399 to 599 dollar price point.

Best NAS You Can Buy Right Now for Under $249 at the end of 2025

As personal data storage requirements continue to rise in 2025, many users are moving away from cloud platforms and monthly subscription services in search of something more private and cost effective. A dedicated NAS, or network attached storage system, allows you to back up photo collections, host a home media library, or manage small business files while keeping full control of your data and avoiding ongoing fees. The good news is that the market now includes several capable options priced at or under 249 dollars. Improvements in low power processors, wider use of DDR5 memory, and leaner operating systems have made entry level systems far more powerful than they were even a year ago. They can comfortably handle tasks such as Plex playback, simple virtualization, and lightweight container apps. This article looks at five NAS units currently available within this price bracket, each offering a practical mix of performance, connectivity, and storage flexibility for anyone building a reliable setup on a limited budget.

Important Disclaimer and Notes Before You Buy!

Before looking at specific NAS models, it helps to understand the common limits of systems in this price tier. Most units under 249 dollars arrive without drives, and rely on NVMe or SATA bays that must be filled separately. Some include small onboard storage such as 32GB to 64GB eMMC that only covers the operating system. This means the total cost of a usable setup will usually be higher than the base price. These devices are aimed at home users and personal cloud tasks rather than heavier business workloads. Several models also lack a full NAS operating system and instead use lightweight platforms such as CasaOS or ZimaOS, or provide only a simple interface for local file access and containers. These options are improving, yet they may not offer advanced RAID tools, snapshot automation, or detailed permission control found on systems like Synology DSM or TrueNAS. Overall, these NAS units suit users with some technical confidence or anyone who wants a simple setup with limited depth.

Review of the UGREEN NAS UPS – Is the US3000 120W UPS Any Good?

The UGREEN US3000 is a 120 W DC uninterruptible power supply developed specifically for UGREEN NAS devices that rely on an external DC power brick. Unlike conventional UPS systems that convert AC to DC, this model outputs direct 12 V DC power with a zero-second transfer time, ensuring there is no interruption during a power loss. It is equipped with a 12,000 mAh lithium-ion battery pack made up of four 3000 mAh cells, providing a rated energy of 43.2 Wh and up to around ten minutes of backup time depending on workload. Measuring 120.6 × 80.5 × 29.6 mm and weighing approximately 439 g, the US3000 is compact enough for desktop environments where space is limited. Beyond supplying short-term emergency power, it integrates with UGOS Pro software via a USB communication cable, allowing automated shutdown, timed standby, and restart once power is restored. This focus on seamless hardware and software compatibility makes the US3000 notable for users running UGREEN NAS systems that need to mitigate risks of data corruption caused by sudden outages.

UGREEN US3000 UPS Review – Quick Conclusion

The UGREEN US3000 is a purpose-built DC UPS that prioritizes seamless integration with UGREEN NAS systems over broad flexibility. Its compact aluminum chassis houses a 12,000 mAh lithium-ion battery pack capable of delivering 120 W output with zero-second transfer time, ensuring that a connected NAS continues running long enough to perform a safe shutdown. Unlike traditional AC-based UPS units, it avoids conversion inefficiency by supplying direct DC power, while its USB link with UGOS Pro enables automatic shutdown, timed standby, and restart functions. Testing confirmed reliable operation across scenarios from immediate power loss to scheduled shutdowns, with system logs capturing events in under two seconds. However, its design is deliberately narrow in scope: it supports only one NAS at a time, does not extend to routers or switches, and offers limited runtime of around ten minutes under load. For users operating within the UGREEN ecosystem, it provides an efficient and well-integrated safeguard against data corruption during outages. For those needing multi-device protection or long-duration backup, its constrained design and compatibility limit its broader applicability.

Why the UGREEN US3000 UPS is Important/Interesting

Uninterruptible power supplies are not new, but most consumer models are designed for general computing and rely on bulky lead-acid batteries with AC pass-through. The UGREEN US3000 differs by offering a DC-to-DC solution that matches the external power design of UGREEN NAS units. This means it eliminates the inefficiency of double conversion and avoids the audible transfer delays that can occur with traditional UPS hardware. With a 120 W output ceiling, it is tailored for single-device use rather than multiple systems, but that specificity ensures closer integration with the NAS’s power and shutdown controls. From a technical perspective, its lithium-ion battery pack offers greater energy density than lead-acid, allowing the device to remain compact while still covering several minutes of safe system operation during an outage.

The importance of this UPS becomes clearer when examining how it interacts with UGOS Pro. Unlike generic solutions, the US3000 communicates directly with the NAS operating system via a USB connection, exposing monitoring and automation options in the control panel. Users can configure automatic shutdown after a set period, trigger standby to conserve remaining charge, or enable auto-restart once mains power returns. These features are not just convenient but directly address the risks of corrupted writes, incomplete backups, or damaged RAID arrays during sudden power loss. Given that UGREEN NAS systems are designed for small offices and home use, where environments may not include larger enterprise-grade UPS equipment, the US3000 effectively bridges that gap by offering a purpose-built, compact, and integrated safeguard.

UGREEN US3000 UPS Review – Design

The UGREEN US3000 follows a compact, rectangular form factor with dimensions of 120.6 mm in length, 80.5 mm in width, and 29.6 mm in thickness. Its weight of just under 440 g makes it relatively lightweight for a UPS, reflecting its focus on portability and single-device deployment rather than large-scale power protection. The outer chassis is made from anodized and sandblasted aluminum alloy, which gives it improved durability compared with plastic housings and also aids in passive heat dissipation. The choice of materials ensures a consistent finish that aligns visually with UGREEN’s NAS enclosures, providing an integrated appearance when the two devices are used together on a desktop.

Connectivity is handled entirely through DC and USB ports positioned on a single side of the device. The panel includes a DC input, a DC output, a USB-C port for data communication, and a power button. The fixed DC cable has a length of approximately 28 cm, while the included USB-A to USB-C cable measures around 53 cm, allowing flexible placement next to a NAS system without excess cabling. Each port and control is clearly labeled with printed icons, reducing the likelihood of incorrect setup. Unlike conventional UPS systems that feature multiple AC sockets, the US3000 focuses on a single dedicated output, reflecting its intended role as a companion unit for UGREEN NAS models rather than a general-purpose UPS.

The packaging of the device mirrors UGREEN’s approach with its NAS line, offering clear product imagery and specification highlights on the box exterior. Inside, the unit is provided with a base stand for stable positioning, the aforementioned data cable, and basic documentation. This is a minimalist package compared to conventional UPS units, which often include multiple adaptors or accessories, but the streamlined approach ensures that setup remains straightforward for the intended NAS integration. The inclusion of a stand is particularly useful given the slim design, as it helps keep the UPS stable in vertical placement while maintaining airflow around the chassis.

From a design perspective, the emphasis is on simplicity and integration rather than flexibility. The device does not feature multiple voltage outputs, nor does it support powering unrelated devices such as routers or switches. Instead, its DC pass-through design, small footprint, and single-device orientation mark it as a specialized tool. This aligns with UGREEN’s approach of building a controlled ecosystem around its NAS systems, where accessories are engineered for direct compatibility. The US3000 therefore sits between consumer-grade battery packs and enterprise UPS units, offering a focused solution that fits into a narrow but clearly defined usage scenario.

UGREEN US3000 UPS Review – Internal Power Design

Inside the UGREEN US3000 is a straightforward but carefully constructed layout built around a 12,000 mAh lithium-ion battery pack. The pack consists of four SunPower INR18650-3000 cells, each rated at 3000 mAh and 11.1 Wh, connected in series to deliver a combined rated energy of 43.2 Wh at 14.4 V. The cells are wrapped in foam insulation and secured with adhesive to minimize movement, with spot-welded nickel strips linking them. Additional barley paper insulation is applied around the terminals for added protection. This design choice allows the UPS to maintain compact dimensions while ensuring sufficient runtime for controlled NAS shutdowns.

Battery management is handled by a Chipsea CBM8580KV6NT protection IC. This chip monitors voltage, current, and temperature across the pack, ensuring safe charging and discharge cycles. It communicates with the system host via SMBus 3.1, which enables the UPS to relay real-time status to the NAS when connected through USB. Supporting components include current sense resistors, thermistors, and MOSFETs for switching and power regulation. Together, these ensure not only that the battery operates safely but also that the UPS can reliably deliver 120 W maximum output without voltage instability.

Voltage conversion is performed by a dual-stage arrangement. A Texas Instruments TPS55289 synchronous buck-boost converter handles a wide input range up to 30 V and can output between 0.8 V and 22 V. Alongside this, a SouthChip SC8002 synchronous buck controller manages current limiting and efficiency across dual channels. Power MOSFETs from CR MICRO and NCEPower are used for pass-through control and output switching, while a GigaDevice GD32F303RCT6 Cortex-M4 microcontroller coordinates the overall system, including communication with the NAS. Passive cooling, adhesive reinforcement on inductors and capacitors, and fuses at both input and battery ends further underline the design focus on stability and safety.

UGREEN US3000 UPS Review – Testing with UGREEN NASync Systems

To evaluate the UGREEN US3000, three operational scenarios were simulated: immediate power loss with continued operation, automatic shutdown under UPS control, and timed shutdown with automatic restart when power returned. In each case, the NAS was connected to the UPS using both the DC input and USB communication cable to ensure full integration with UGOS Pro. The first test involved disconnecting mains power to replicate an outage. The NAS continued running without interruption, with the transfer to battery occurring instantly. System logs registered the event in under two seconds, and normal file access, media playback, and downloads remained available until the battery level dropped to the configured threshold.

In the second test, the system was configured to shut down automatically as soon as the UPS switched to battery mode. Once power was removed, the NAS immediately began its shutdown process. This test showed that the UPS integration with UGOS Pro allowed a fast and orderly shutdown sequence, preventing data corruption or incomplete writes. The reaction time was near instantaneous, and the system was powered down safely without user intervention. This mode may be best suited for environments where uptime during an outage is less critical than ensuring rapid data protection.

A third test focused on timed shutdown, with the UPS set to keep the NAS running for five minutes before initiating a safe power-off. Once mains power was disconnected, the NAS continued operating for the specified period, then shut down as configured. After power was restored, the UPS automatically triggered a restart of the NAS, returning it to full operation within a few minutes. This confirmed the UPS’s ability not only to handle outages but also to manage recovery without manual restart, which is beneficial for users who may not be present during a power failure.

During all tests, the device’s limitations became apparent. With a 120 W maximum output and battery capacity limited to 43.2 Wh, it cannot sustain extended operation. Its role is restricted to ensuring controlled shutdowns and short bridging periods rather than providing long-term backup. Furthermore, it supports only one NAS system via DC pass-through, so it cannot protect additional hardware such as routers or switches. Nevertheless, within its defined parameters, the UPS consistently delivered seamless transitions and executed software-triggered events reliably, confirming that its functionality matches its intended scope.

UGREEN US3000 UPS Review – Conclusion & Verdict

The UGREEN US3000 fills a specific role: protecting UGREEN NAS devices from sudden power loss. Its design avoids the bulk and inefficiency of conventional AC-based UPS units by delivering DC pass-through power with zero transfer time. In practice, it provides just enough runtime for the NAS to perform a controlled shutdown, while its software integration ensures automation of both power-off and restart processes. With lithium-ion cells, a compact aluminum chassis, and close alignment with UGOS Pro features, it is engineered as a dedicated accessory rather than a universal power backup solution.

As a result, its usefulness is limited to scenarios where a single UGREEN NAS is the priority. It does not offer multiple outputs or extended backup duration, making it unsuitable for wider network coverage or enterprise requirements. Instead, the US3000 should be viewed as a narrowly focused safeguard that addresses one problem reliably: preventing data corruption and incomplete writes during outages. For users within the UGREEN ecosystem, it is an effective solution, but for broader applications, its scope remains intentionally constrained.
