Il y a quelques mois, j’ai décidé de remplacer mon QNAP TS-464. Ce dernier ne m’avait jamais vraiment convaincu : impression d’un OS mal fichu, performances pas dingues… Bref, il était temps de passer à autre chose. En cherchant une alternative, je suis tombé sur le UGREEN DXP4800 Plus – un nouveau venu sur le marché du NAS, avec des promesses intéressantes : matériel récent, format compact, et un OS maison qui semblait tenir la route. Voici mon retour après plusieurs semaines d’usage intensif…

UGREEN DXP4800 Plus

Aujourd’hui, c’est Flow (lecteur de Cachem) qui s’est proposé de prendre le clavier pour nous présenté son UGreen DXP4800 Plus et l’usage qu’il en fait.

Présentation & déballage

À la réception, bonne surprise côté packaging : soigné, propre, rien à dire. Le NAS lui-même respire la qualité, à la hauteur de ce qu’on retrouve chez QNAP ou Synology. Le boîtier est sobre, bien fini, et se fait discret une fois installé. Côté bruit, rien à signaler, même en charge. On est clairement sur un produit sérieux.

Configuration matérielle

J’ai choisi la version standard du DXP4800 Plus, avec un petit upgrade de la RAM à 32 Go.

Stockage :

• 2 SSD NVMe de 4 To en RAID pour les services critiques (VM, containers, DB…)
• Des disques 3.5″ à 7200 tr/min pour un total de plus de 40 To pour les médias et sauvegardes

Le CPU embarqué est bien plus récent que ce qu’on trouve chez Synology sur des gammes équivalentes. C’est aussi une des raisons de mon choix.

Installation & OS

J’ai gardé l’OS fourni par UGreen. Franchement, aucun souci à l’installation, c’est du plug and play comme on en a l’habitude avec les NAS récents. Pas besoin de réglages complexes ou de tweaks bizarres : ça fonctionne dès le départ.

Et pour les curieux, oui, on peut y installer autre chose (TrueNAS, Unraid…), mais je ne suis pas allé jusque-là pour l’instant.

Utilisation au quotidien : 70 containers Docker

Je suis un gros utilisateur de containers Docker, et le NAS les encaisse sans broncher. Voici une liste (non exhaustive) des services que je fais tourner dessus :

Domotique & maison connectée :

• Home Assistant
• Zigbee2MQTT
• ESPHome
• AppDaemon

Multimédia :

• Jellyfin
• Jellyseerr
• Radarr
• Sonarr
• Komga
• Navidrome

Téléchargement & automation :

• Transmission
• Prowlarr
• Recyclarr
• Authelia
• Autobrr

Sauvegardes & supervision :

• pgBackWeb
• Watchtower
• Portainer
• Uptime-Kuma
• Crowdsec

Divers :

• Actual
• Ghostfolio
• Freshrss
• Meilisearch
• Ombi
• Firefox
• Dozzle
• Ghost
• Money-actual
• Stash
• ModManager

À noter : 4 utilisateurs Jellyfin peuvent streamer en simultané sans aucun lag. Clairement, la machine est stable et tient la charge.

Performances

Je n’ai pas benché précisément les débits, mais aucun ralentissement à signaler, même avec 70 containers actifs.
Pas de bruit excessif, pas de surchauffe, et je ne monitore pas la consommation électrique — mais vu la charge, je suis impressionné par la stabilité.

Comparaison & raisons du choix

J’ai eu plusieurs NAS avant celui-ci : des Synology 2 baies, un QNAP TS-464… Pourquoi avoir choisi le DXP4800 Plus ?

• Matériel plus récent
• OS simple, mais fonctionnel
• Bon rapport qualité/prix
• Marque prometteuse qui évolue vite

UGREEN NASync NAS: One Year Later – The Good, The Bad, and What’s Still Missing?

One year ago, UGREEN made waves in the NAS industry by launching its NASync series through a hugely successful Kickstarter campaign, raising $6.6 million from over 13,000 backers. This new line of NAS devices aimed to offer a cost-effective alternative to established brands like Synology and QNAP, promising powerful hardware, a user-friendly experience, and AI-powered features at a more competitive price. Since its general retail release in mid-2024, UGREEN NASync has been available via Amazon, B&H, and UGREEN’s website, gaining a strong following among enthusiasts and small businesses. But after a year of real-world usage, firmware updates, and customer feedback, does the NASync series truly compete with industry leaders? Has UGREEN delivered on its promises, or are there still major issues preventing it from being a go-to NAS solution? This article will explore where UGREEN has excelled, where it still needs improvement, and whether the NASync series is a worthwhile investment in 2025.

Note – UGREEN are running a promotion during World Backup Day that drops the price significantly on several of their NASync devices on their own website and on Amazon. Find out more here or via the banner link below:

The UGREEN NASync NAS Kickstarter – A Recap

Unlike many hardware startups that struggle with fulfilling Kickstarter orders, UGREEN managed to deliver its NASync units on schedule to most backers, a significant achievement for a crowdfunded product. While there were some reports of faulty units, these appeared to be within normal failure rates for electronics and were generally covered by UGREEN’s replacement and support policies. What truly set UGREEN apart, however, was its unorthodox marketing strategy. Instead of focusing on traditional advertising or securing major sponsorship deals, UGREEN distributed thousands of review units to mid-tier and micro-influencers.

This grassroots approach ensured that discussions about the NASync series remained active and widespread across online tech communities. Unlike companies that pay for high-profile reviews on massive platforms like Linus Tech Tips, UGREEN instead prioritized authenticity and volume, creating long-term engagement from reviewers who actually tested the product in-depth. This strategy has proven successful, keeping UGREEN’s NAS devices relevant in online discussions long after their launch, though it has also meant that larger, mainstream tech publications have not widely covered the NASync series. While this marketing approach has helped build a loyal user base, it also raises concerns about how well UGREEN’s products will compete with more established brands in the long run if they do not gain broader mainstream recognition.

The UGREEN NAS Software Development So Far…

When the NASync series launched, its UGOS operating system was one of its most significant unknowns. Unlike Synology DSM or QNAP QTS, which have been refined for years, UGOS was a first-generation NAS OS that lacked many critical features and refinements expected by experienced users.

Over the past year, UGREEN has made steady improvements, rolling out regular firmware updates that have expanded its functionality. One of the most notable additions is the inclusion of Jellyfin as a native app, providing an alternative media server option for users who want to stream videos without needing complex third-party installations.

However, Plex support remains absent, a surprising omission considering Plex is the most widely used NAS-based media server. Another major shortcoming is the lack of iSCSI support, which is essential for business users, virtualization environments, and enterprise-level storage solutions.

While UGREEN has stated that iSCSI support is on their roadmap, it has yet to be implemented, making the NASync series a less viable option for professional users who rely on networked block storage solutions. Despite these improvements, UGOS is still not as polished or feature-rich as competing NAS operating systems, and for users who need advanced storage capabilities, its limitations remain a concern.

UGREEN NAS and Security – After 1 Year

Security was one of the biggest concerns when UGREEN first launched its NASync series, as it initially lacked two-factor authentication (2FA) and had limited built-in protections for remote access. Over the past year, UGREEN has addressed some of these concerns, adding 2FA and expanding firewall settings to include IP blocking, MAC filtering, and customizable access controls.

These updates have significantly improved overall security, but the absence of dedicated anti-ransomware protection remains a critical weakness. Competing NAS brands such as Synology and QNAP have introduced automated ransomware protection tools, snapshot-based rollback systems, and real-time anomaly detection, features that UGOS has yet to incorporate.

The NASync series does provide basic malware and antivirus scanning, but it is still lacking the more advanced automated security solutions that have become standard in the NAS industry. Users who are particularly concerned about security may prefer to disable UGREEN’s remote access services and instead use third-party VPN solutions like Tailscale or even install an alternative NAS operating system such as TrueNAS or UnRAID, both of which UGREEN supports without voiding hardware warranties.

UGREEN NAS and Local AI Use

UGREEN has been heavily investing in AI-driven functionality, integrating photo recognition, AI-assisted indexing, and content categorization into UGOS. Unlike cloud-based AI solutions, these run entirely on the NAS itself, keeping user data private and locally processed. This makes UGREEN one of the few NAS brands to offer AI-powered automation without cloud dependencies, a feature that privacy-conscious users appreciate.

However, with the recent announcement of UGREEN’s new IDX series, which focuses even more on AI-powered storage and advanced computing, there is growing uncertainty about the long-term future of the NASync series. It remains unclear whether UGREEN will continue to develop UGOS at the same pace for NASync devices or shift focus toward its newer, AI-driven IDX models.

While UGREEN insists that the NASync and IDX series will coexist as separate product lines, there is a possibility that software development for NASync may slow down in favor of newer hardware platforms. This uncertainty may deter potential buyers who want long-term software support guarantees.

UGREEN NASync Devices and Mixed Global Availability

Despite the NASync series’ popularity, UGREEN has struggled to expand its global distribution network. While the devices are widely available in the US, Germany, and select European markets, many regions still lack direct purchasing options. The UK recently saw improved availability, but other regions remain underserved, forcing potential buyers to import devices at higher costs.

Given the strong demand and continued interest, it is surprising that UGREEN has not prioritized expanding its retail presence globally. If the company wants to compete seriously with major NAS brands, broader availability through additional international retailers should be a key focus moving forward.

UGREEN NAS 1 Year Later – Verdict

One year in, UGREEN’s NASync series has made a strong impression in the NAS market, proving that it is more than just a one-off experiment. The company has demonstrated consistent software development, ongoing support, and a commitment to hiring industry experts to strengthen its NAS business. However, the NASync series still falls short in key areas, particularly iSCSI support, security automation, and mainstream availability. For enthusiasts and tech-savvy users willing to customize their setup, UGREEN’s NASync devices offer solid hardware at an attractive price. But for those who expect a polished, fully mature NAS experience, Synology and QNAP still lead the market. UGREEN has the potential to become a serious competitor in the NAS space, but its future success depends on how aggressively it continues to develop UGOS, improve security, and expand its global footprint.

20% OFF UGREEN NAS this World Backup Day

UGREEN is currently running a Work Backup Day promotion, offering a 20% discount on NASync devices purchased through their official website and Amazon. This limited-time deal runs from March 25th to March 31st, making it an excellent opportunity for those considering a UGREEN NAS for data protection and backup storage. With the growing importance of secure, local backups, especially for businesses and home users managing large datasets, this promotion provides a cost-effective way to invest in a NAS solution. Whether you’re looking to set up automated backups, secure your media collection, or expand your existing storage infrastructure, the discount makes UGREEN’s already competitive pricing even more attractive. However, with global availability still being somewhat inconsistent, buyers should check regional stock levels and shipping options before purchasing.
