Ugreen continue son offensive sur le marché des NAS avec un nouveau 4 baies ambitieux : UGREEN NASync DXP4800 Pro. Après le DXP4800 Plus de l’an dernier, nous avons pu passer plusieurs jours avec le modèle Pro, une version musclée pensée pour les usages avancés, le multitâches intensif et les environnements exigeants sans compromis sur la simplicité d’utilisation. Sur le papier, la promesse est solide. En pratique, tout n’est cependant pas parfait…

UGREEN NASync DXP4800 Pro

Là où le DXP4800 Plus s’appuie sur un Intel Pentium Gold 8505, le DXP4800 Pro passe sur un processeur Intel Core i3-1315U, offrant plus de puissance brute et une meilleure capacité de traitement pour des charges lourdes : virtualisation, transcodage multimédia, IA, Docker…

Intérieur du DXP4800 Pro

C’est là que les choses changent ! Le DXP4800 Pro est animé par un processeur Intel Core i3-1315U capable d’atteindre 4,50 GHz  (6 cœurs, 8 threads) avec iGPU intégré. Il est épaulé par 8 Go de RAM DDR5 (extensibles à 96 Go). On aurait préféré voir 16 Go pour ce modèle Pro. Le score PassMark est de 11 183 points ! Pour ce tarif, il largue tous les concurrents…

Installation des disques et SSD

Les disques durs 3,5 pouces s’installent assez facilement, sans outils. Les chariots sont différents de ceux de Synology ou QNAP, mais ils sont fonctionnels.

Pour installer un SSD SATA, il faut retirer une fixation en plastique (en bas à droite sur la photo ci-dessus) via un outil fourni. Attention à ne pas forcer trop fort au risque d’abimer la pièce. Le NAS dispose de 2 emplacements pour SSD NVMe, accessibles via une trappe sous l’appareil. C’est également ici que vous pourrez augmenter la RAM. L’ajout de pâte thermique (fournie) et le rôle de dissipateur thermique du capot en aluminium sont des points positifs.

De notre point de vue, le NAS n’est pas suffisamment surélevé. Les patins sous l’appareil ne sont peu assez haut, ce qui limite la circulation de l’air et favorise les vibrations. De nombreux utilisateurs recommandent l’ajout de petits amortisseurs en élastomère pour corriger ce léger défaut. Nous validons ce choix.

UGOS

Nous vous avons déjà présenté le système embarqué UGOS précédemment. Nous avons bien conscience que Ugreen est encore jeune sur le marché et il faut savoir être indulgent. Le système évolue régulièrement sans rivaliser pour le moment avec les ténors du marché. Cependant, il n’a pas à rougir, car il sait déjà répondre à de nombreux usages.

Installation d’UGOS

L’utilisateur doit taper dans son navigateur find.ugnas.com pour trouver son NAS sur le réseau. L’installation se fait en 4 étapes (voire ci-dessous) :

Par rapport à notre précédent test, l’interface est désormais bien en français.

Une fois l’installation terminée, le NAS redémarre… il ne reste plus qu’à se connecter avec l’identifiant et le mot de passe saisis précédemment. Un nouveau guide se lance pour accompagner l’utilisateur dans les premières étapes :

• Découverte de l’interface ;
• Création d’un volume de stockage ;
• Premier dossier partagé ;
• Découverte d’UGREENlink pour l’accès à distance.

Note importante : lors du test précédent, nous pensions avoir commis une erreur, mais non… le service SMB (partage réseau) est désactivé par défaut. Cela veut dire que si vous ne faites rien, le NAS n’est pas accessible par le réseau (Windows, macOS ou Linux).

Usage au quotidien

UGOS est un système Linux optimisé pour le stockage en réseau. Il propose un ensemble de paramètres, auquel on peut ajouter des fonctionnalités via le Centre d’applications : Antivirus, Download Center, Text Edit, etc. Ugreen a fait le choix de privilégier Docker pour compléter son environnement applicatif.

Le fabricant propose une application mobile tout-en-un qui permet de profiter de son NAS à distance ou sur son réseau local. Il faut avouer qu’elle est complète et bien pensée. Ugreen propose également une application de bureau (Windows et macOS), ainsi qu’une adapté à Apple TV et Android TV. Elles permettent d’accéder aux fichiers, au statut du NAS, aux notifications… mais aussi au visionnage de vidéo, etc. Tout y est, un véritable couteau suisse !

Ugreen déploie fréquemment des mises à jour pour corriger des bugs et soucis de traductions, mais aussi pour améliorer les performances et ajouter des fonctionnalités. Un NAS, c’est un investissement sur le long terme. Aujourd’hui, les NAS sont régulièrement mis à jour… et surtout pendant de nombreuses années.

Nouvel entrant et tolérance

Ugreen est nouveau sur le marché des NAS, mais ce n’est pas un novice. L’entreprise possède une solide expérience industrielle et maîtrise déjà la conception matérielle et logicielle. Le fabricant connait également très bien ce secteur exigeant, dominé par des acteurs comme Synology et QNAP. Côté matériel, le produit tient la route…

Sur la partie logicielle, UGOS reste limité pour un usage avancé. S’il répond à 90% des particuliers, certains pourraient être déçus. La majorité des utilisateurs parient sur des mises à jour futures pour corriger le tir dans les prochains mois. Ugreen en a bien conscience… À noter qu’il propose également la possibilité d’installer de systèmes alternatifs comme OMV, TrueNAS, Unraid, etc. Une approche ouverte, que beaucoup apprécient.

L’essentiel est là : une base matérielle fiable et une volonté claire d’évoluer.

Performances du DXP4800 Pro

Dans la première partie des tests, nous allons évaluer les performances des transferts à travers un réseau 10 Gb/s (entre le NAS et des ordinateurs). Ensuite, nous regarderons les capacités du processeur, en analysant ses performances globales…

Vitesses dans les transferts

Depuis plusieurs années, nous avons mis en place un protocole de tests rigoureux fournissant des données fiables et comparables avec les performances des autres NAS. Pour cela, nous utilisons 4 applications de mesure différentes (2 sous macOS et 2 sous Windows) et réalisons en plus des transferts de fichiers de tailles variées dans les deux sens (NAS -> Ordinateur puis Ordinateur -> NAS) :

• Petites tailles : 100 fichiers de 500 Ko à 12 Mo (MP3, photos, documents Office)
• Tailles moyennes : 30 fichiers de 12 à 350 Mo (DivX, images RAW, archives ZIP)
• Fichiers volumineux : 10 fichiers avec une taille comprise entre 4 et 10 Go (MKV, ISO)

À la suite des tests, une moyenne des transferts est calculée et nous la représentons sous forme de graphiques exprimée en mégaoctets par seconde (Mo/s). Plus le nombre est élevé, plus le NAS est rapide. Pour notre évaluation du DXP4800 Plus, nous avons configuré un premier volume avec 2 SSD NVMe en RAID 0, puis un second volume avec 3 SSD SATA en RAID 5.

RAID 0

Le NAS propose d’excellentes performances en lecture. Le système est réactif et les transferts solides. On voit tout de suite le gain offert par le nouveau processeur. Si les performances en écriture progressent (par rapport au DXP 4800 Plus), nous restons un peu sur notre faim.

RAID 5

Les débits vous surprennent… nous aussi. En lecture, le RAID 5 SATA assure et nous sommes sur des performances proches du RAID 0 NVMe. En écriture, les SSD SATA font même mieux sur les petits fichiers et ceux de taille moyenne. Par contre, sur les gros fichiers, les choses sont différentes.

Performances générales

Avec son nouveau processeur, Ugreen propose un NAS offrant des capacités bien plus étendues. Comparons rapidement celui-ci

Vous l’aurez compris, le changement opéré par Ugreen n’est pas anodin. On se retrouve avec un processeur taillé pour les tâches complexes ou il n’aura pas de difficulté : chiffrement des données, virtualisation, conteneurisation ou encore le transcodage vidéo. Il sera difficile de le mettre en difficulté. Seul regret, la présence de seulement 8 Go de RAM par défaut. On ne va pas se mentir, c’est un peu juste pour exploiter pleinement le potentiel de ce NAS : 16 Go auraient été préférables.

IA & DXP 4800 Pro

Ugreen a été intégré ici et là quelques touches d’IA dans ses applications maisons (notamment dans son application pour les photos). Mais nous avons voulu aller plus loin et tenté l’expérience des modèles Qwen2.5:3B et Gemma2:2B avec Ollama. Ils fonctionnent très bien avec ce NAS et répondent en quelques secondes. Attention, l’IA consomme beaucoup de ressources : processeur et RAM. Aussi, nous avons constaté une certaine limitation dans la gestion des ressources avec Docker, certainement pour protéger les fonctions de base du NAS.

Consommation électrique et nuisance sonore

Le ventilateur arrière est relativement discret. Côté consommation électrique, le NAS affiche environ 27 W en usage normal (avec 2 SSD NVMe et 3 SSD SATA) et jusqu’à 45 W en charge plus soutenue.

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.
