XikeStor FS5104DH & FS510402DH: All-Flash NAS Systems with Quad 10GbE and PCIe 4.0 Expansion

XikeStor has announced two desktop NAS models: the FS5104DH and FS510402DH. These systems combine Intel Core i5 mobile-class processors with M.2 NVMe storage and multiple 10GbE ports. Both are designed for users seeking compact systems with high throughput and flash storage performance. The models differ slightly in expansion options and chassis dimensions, offering users a choice depending on capacity and connectivity requirements. While they do not include traditional 3.5″ drive bays, their full flash-based architecture and high-speed networking capabilities place them in a growing category of SSD-optimized NAS platforms.

FS5104DH & FS510402DH – Key Specifications

The FS5104DH and FS510402DH share the Intel Core i5-12450H processor (8 cores, 12 threads), which provides higher performance than typical NAS systems using lower-power CPUs. This CPU uses Intel’s Alder Lake-H architecture, with a hybrid design that includes four performance cores and four efficiency cores, offering improved multi-threaded performance and better energy efficiency. With support for DDR5 memory up to 64GB and four M.2 NVMe slots, both models are focused on SSD-based data access for tasks requiring high input/output performance. These specifications are well-suited to workloads such as real-time file sharing, virtualized services, and containerized deployments.

The FS510402DH model adds dual U.2 SSD support, providing the option to use enterprise-grade storage devices with higher endurance and sustained performance under heavy I/O loads. It also includes a PCIe 4.0 x8 expansion slot, allowing users to add specialized hardware if needed, such as GPUs for transcoding, AI acceleration, or additional high-speed network interfaces.

Hardware and Connectivity

The Intel Core i5-12450H processor used in both models is part of Intel’s Alder Lake-H series. It offers a base clock speed of 2.0GHz and turbo capability up to 4.4GHz. This CPU includes both performance and efficiency cores, supporting modern instruction sets, hardware virtualization, and AVX2. This makes the systems appropriate for users running lightweight virtual environments, media processing applications, or software containers. Hardware support for VT-x, VT-d, and AES-NI also makes these models suitable for encrypted file hosting and virtualized services with device passthrough. Memory support includes two SO-DIMM DDR5 slots, operating at up to 5200 MHz depending on configuration. Both NAS units come pre-equipped with 16GB and can be upgraded to 64GB. DDR5 memory improves bandwidth and efficiency, which may benefit users with concurrent workloads or services that rely heavily on RAM, such as metadata indexing, caching, and virtual machine hosting.

Storage is handled via four M.2 2280 NVMe SSD slots. In the FS510402DH, two additional U.2 bays support enterprise SSDs. These U.2 drives, often used in data centers, offer advantages such as power loss protection, longer write endurance, and sustained IOPS performance. The inclusion of PCIe 4.0 x8 in the FS510402DH provides flexibility for those requiring additional network bandwidth or hardware acceleration. This may be important in situations where AI tasks or intensive transcoding are involved, or where multiple VMs require independent network interfaces.

10GbE Networking and Use Case Scenarios

Both models offer four 10-gigabit Ethernet ports, split evenly between RJ45 and SFP+. This allows deployment in environments that use either copper or fiber infrastructure. The FS510402DH identifies specific network controllers — Intel X550 for copper and X710 for fiber — which are widely supported across Linux, Windows, and BSD-based systems. These controllers are known for their stability and compatibility in enterprise applications. Link aggregation is supported, enabling up to 40Gbps of combined throughput when connected to a compatible switch. This allows multiple users to simultaneously access data at high speeds or enables redundant network paths for failover. Environments that could benefit from this setup include video production studios working with 4K or 8K footage over SMB or NFS, research environments handling multi-terabyte datasets, or businesses deploying virtual desktop infrastructure (VDI) solutions backed by NVMe flash storage.

Build Quality and I/O Design

The enclosures for the FS5104DH and FS510402DH are constructed from CNC-machined aluminum with an anodized finish. This design assists in passive heat dissipation and contributes to durability. A single fan is used for active cooling, and the overall noise profile is intended to be low enough for office or studio use. The metal chassis also provides a more robust build compared to consumer-grade plastic NAS devices.

Both systems include Mini DisplayPort and HDMI outputs, allowing the NAS to be accessed directly with a monitor and input devices. This may be useful for initial configuration, local GUI access, or monitoring system status without relying on remote access tools. A MiniDP to DP cable is included with the FS510402DH. USB 3.2 connectivity is also present in both models, with Type-A and Type-C ports supporting up to 10Gbps transfers for external storage devices, UPSs, or peripheral hardware. These ports enable fast offloading of data, peripheral expansion, or direct-to-NAS backups without requiring a PC intermediary.

Pricing and Availability

No official pricing or launch schedule has been provided for the FS5104DH or FS510402DH at this time. Based on component selection and feature set, the systems are positioned for small to medium business deployments and users requiring compact flash-based storage with 10GbE support. Additional announcements regarding retail availability, regional distribution, and bundled software support are expected. Once these details are confirmed, this section will be updated to reflect available SKUs, configurations, and potential comparisons with competing NAS systems

Avant de commencer, cet article a pour but de vous informer sur une installation photovoltaïque. En aucun cas, je ne suis un professionnel. Je souhaite simplement vous partager mon retour d’expérience. Il est essentiel que vous effectuiez également vos propres recherches pour votre installation. Chaque projet est unique en fonction des besoins énergétiques de votre maison. Je vous donnerai ici les bases pour une installation photovoltaïque.

Vous travaillerez avec un courant de 230 V, soyez prudent. Assurez-vous de couper toute votre installation avant toute intervention dans le tableau électrique de votre maison.

Cela fait plusieurs années que je réfléchis à une installation photovoltaïque. Ma maison est entièrement électrique, que ce soit pour le chauffage, la table de cuisson ou l’eau chaude, ce qui entraîne une consommation électrique importante tout au long de l’année. L’augmentation des prix de l’électricité ces dernières années m’a poussé à relancer mon projet d’installation de panneaux photovoltaïques.

Après environ cinq mois de recherche pour identifier la meilleure installation adaptée à ma maison, que ce soit en termes de matériel, de calcul de puissance nécessaire ou de démarches administratives, j’ai finalement pu installer les panneaux photovoltaïques sur ma toiture.

Les préjugés sur le solaire

« Ça fonctionne que quand il y a du soleil ! »
C’est vrai, mais pas seulement. Même avec un ciel couvert, la lumière diffuse permet une certaine production d’électricité. Cette production peut facilement couvrir le talon de consommation de votre maison, voire bien plus. (Actuellement, lors de la rédaction de cet article, le ciel est couvert et je produis 1 200 W tout en faisant fonctionner mon lave-linge.)

« L’hiver, ça ne va rien produire ! »
Moins que pendant le printemps ou l’été, c’est certain. Mais même en hiver, un ciel clair permet une production significative. Lorsque vous vous lancez dans un projet solaire, il est important de penser que de mars à octobre, vous réduirez considérablement votre consommation sur le réseau électrique. L’hiver sera moins productif, mais cela ne signifie pas une absence totale de production.

« L’été, ça va beaucoup produire. »
Contrairement à ce que l’on pourrait croire, l’été n’est pas la meilleure saison pour la production solaire. En effet, les panneaux chauffent davantage, ce qui réduit leur efficacité, et le soleil est plus haut dans le ciel, donc moins perpendiculaire aux panneaux. Les meilleures périodes pour la production sont généralement avril et mai. Cela ne signifie pas que la production chute en été, mais simplement que ce n’est pas la période où vous atteindrez vos records de puissance.

« Il y a beaucoup d’arnaques parmi les revendeurs. Comment savoir si le devis que je vais recevoir est correct ? »
Il est vrai que le secteur du solaire est une cible privilégiée pour les arnaques, qu’elles soient téléphoniques ou par démarchage à domicile. Après plusieurs mois passés sur un groupe Facebook animé par des professionnels, j’ai pu observer les différentes astuces utilisées par ces entreprises peu scrupuleuses suite au message de personnes ce trouvant dans ce cas. Vous trouverez plus bas un paragraphe vous expliquant comment éviter ces pièges.

Je terminerai ce paragraphe par une citation de UFC-Que Choisir : « Chaque kWh produit, c’est un kWh en moins sur la facture. »

Les termes et abréviations à connaître

Il y a plusieurs termes et abréviations à connaître avant de vous lancer dans vos recherches.

Watt Crête : Quand on parle de la puissance qu’un panneau peut produire, cela sera exprimé en watt-crête avec l’unité Wc. Par exemple, un panneau de 500 Wc pourra produire au maximum 500 W à son plus haut niveau de puissance. On ne peut pas dire qu’un panneau produit 500 W, car son courant va varier de 0 à 500 W. Il ne va pas faire du 0 puis 500 W, d’où le mot « crête » qui indique ici sa puissance maximale.

MO / OC : Pour la partie onduleur, il en existe deux types. Nous avons les onduleurs centraux, souvent écrits OC, et les micro-onduleurs, indiqués MO. Nous reviendrons sur les explications plus bas.

Pour la partie câble électrique, vous verrez souvent parler de 3G2,5 mm², 3G6 mm² ou tout simplement 6 mm². Cela correspond au nombre de fils dans un câble et à leur diamètre. Par exemple, pour un câble 3G2,5 mm², cela signifie que nous avons un câble avec 3 fils (le plus souvent phase, neutre, terre) d’un diamètre de 2,5 mm² chacun.

Le talon ou bruit de fond de votre maison, c’est quoi ? C’est tout simplement l’énergie que votre maison consomme au repos, quand vous n’êtes pas présent, par exemple. Entre tous les appareils en veille, votre box internet, votre réfrigérateur, tout cela consomme en permanence. Par exemple, dans mon cas, ma maison consomme entre 200 et 300 W.

Auto-consommation : Cela signifie que nous allons consommer directement ce que nos panneaux vont produire.

Le surplus : Le surplus, c’est ce que nous allons produire mais ne pas consommer directement. Par exemple, si vous produisez 2000 W et que votre maison en consomme seulement 500 W, les 1500 W restants vont être envoyés sur le réseau.

DC / AC : DC signifie courant continu, comme le 12 V de votre voiture, identifiable par des fils rouges pour le pôle positif et noirs pour le négatif. Pour AC, c’est pour le courant alternatif de votre maison, identifiable par le neutre avec fil bleu et la phase avec un fil rouge ou marron voir noir.

Kit Plug and Play : Ce sont des kits à monter facilement qui sont simplement à brancher sur une prise de votre maison. Mais ce type de kit risque de disparaître en septembre 2025, la norme va changer, interdisant à un générateur d’électricité d’être branché au moyen d’une prise.

Le calepinage : C’est un schéma d’implantation pour le montage des rails sur votre toit.

Les principaux équipements d’une installation.

Une installation comprendra plusieurs éléments indispensables, voici la liste:

• Un système de fixation pour les panneaux (en toiture ou au sol voir traqueur solaire) ;
• Des panneaux solaire ;
• Un coffret électrique de type DC et AC. Selon le type d’installation, seul un coffret AC peut être nécessaire ;
• Un onduleur centrale ou des micros onduleur.

Les panneaux photovoltaïques

Les panneaux, c’est comme les cartes graphiques ou les CPU de nos ordinateurs, cela évolue chaque année. Actuellement, les panneaux sont de 450 à 500 Wc, et on parle déjà de 600 Wc pour la fin 2025. Il faut aussi prendre en compte la taille des panneaux. Pour les modèles en dessous de 450 Wc, leurs dimensions sont de 1 134 mm x 1 762 mm. Au-delà, pour les modèles de 500 Wc par exemple, la largeur reste à 1 134 mm, mais la hauteur passe à 1 994 mm.

Il existe également plusieurs types de cellules, dont les N-Type, qui sont les plus courantes en ce moment. Vous entendrez aussi parler de panneaux bi-verre ou bi-faciaux. Un panneau classique est composé d’une vitre de 2 mm d’épaisseur, de cellules photovoltaïques et d’un fond opaque. Les panneaux bi-verre, eux, sont composés d’une vitre de verre de 2 mm, de cellules photovoltaïques sur les deux faces (avant et arrière), et d’une seconde vitre de verre de 2 mm. Ainsi, ces panneaux peuvent produire de l’électricité des deux côtés.

Cependant, la production de la face arrière n’est pas comptée dans la puissance maximale en Wc indiquée pour le panneau. Vous vous demandez peut-être pourquoi produire à l’arrière, alors que le soleil est devant ? Les panneaux bi-faciaux ont un espace entre les cellules qui laisse passer la lumière. Ce type de panneau est particulièrement efficace pour une installation au sol, par exemple avec des graviers blancs qui reflètent la lumière sur la face arrière. Aujourd’hui, la plupart des grands panneaux sont bi-faciaux et sont également installés en surimposition sur les toitures, ce qui leur donne un avantage. Grâce à leurs deux couches de verre, soit une épaisseur totale de 4 mm, ils sont aussi plus résistants à la grêle. Un panneau produit un courant de type DC (courant continu), et au bout de ses câbles, vous trouverez des connecteurs MC4. Les panneaux sont garantis 25 ans.

Le kit de fixation

Il y a principalement 3 façons de monter ses panneaux. La première et la plus facile, au sol, sur une toiture en sur imposition (Cela veux dire légèrement au dessus de votre toiture) ou sur un traqueur solaire.

• Au sol : Si vous souhaitez faire votre installation seul avec facilité et que vous possédez un bout de terrain dégagé de toute ombre, le montage au sol sera la meilleure solution. Attention tout de même, les kits vendus où il faut ajouter du poids dans un bac peuvent être un peu légers. Les panneaux ont une grande prise au vent, et il n’est pas rare de voir ce genre de support se renverser sous l’effet du vent. Je vous recommanderais de réaliser une petite fondation. Autre avantage : ici, pas de démarche administrative. Nous y reviendrons plus bas.
• Sur toiture : Installer des panneaux sur un pan de toit présente l’avantage de ne pas occuper d’espace au sol. L’installation sera plus complexe, mais cela ne posera pas de problème pour un professionnel. Étant donné que cela modifie l’apparence physique de votre maison, une démarche administrative est nécessaire. Cette démarche peut être réalisée par l’entreprise qui effectue les travaux, vous évitant ainsi toute complication, ou par vous-même si vous effectuez l’installation seul. Ce type de montage inclut également les toits plats, qui disposent de systèmes spécifiques, ainsi que les carports. La marque de référence dans ce domaine est K2 Systems.
• Un traqueur solaire : Un traqueur solaire est un mât installé au sol qui suit le soleil tout au long de la journée, permettant aux panneaux de toujours produire à leur maximum. L’inconvénient est la limite du nombre de panneaux pouvant y être montés. Il existe très peu de modèles adaptés aux particuliers, ils peuvent être très coûteux et sont généralement limités à un maximum de quatre panneaux.

Le coffret DC / AC

C’est un nouveau tableau électrique à monter qui sera dédié à votre système solaire. Il possédera des disjoncteurs, la passerelles de connexion… Il sera relié au tableau électrique de votre maison pour y injecter l’électricité que vous allez produire.

Les onduleurs

Comme indiqué précédemment, il y a deux types d’onduleurs : les onduleurs centraux et les micro-onduleurs, chacun ayant ses avantages et inconvénients.

L’onduleur central, aussi appelé onduleur à chaîne, sera installé près de votre installation électrique. Au niveau des panneaux, ceux-ci seront branchés en série et un courant DC arrivera sur celui-ci. Il y a quelques années, ces onduleurs avaient un inconvénient majeur : ils géraient mal les zones d’ombre sur votre champ de panneaux. Aujourd’hui, c’est moins le cas. Les panneaux ont évolué, ils sont divisés en plusieurs zones de production et les onduleurs sont plus « intelligents ». Vous ne pourrez pas superviser individuellement vos panneaux ; si l’un d’eux a un défaut, il faudra tous les tester pour trouver le coupable. L’avantage est le coût d’achat, qui sera moins élevé que celui des micro-onduleurs. Ils sont généralement garantis 10 ans. Les marques les plus connues et de bonne qualité sont Fronius, SMA et Huawei.

Pour les micro-onduleurs, eux seront placés sous les panneaux. Selon la marque, il peut y avoir un micro-onduleur par panneau, voire un micro-onduleur pour deux ou plus. Il sera possible d’avoir le détail de la production de chacun. Leur grand avantage est de très bien gérer les zones d’ombre. Si vous avez, par exemple, un panneau à l’ombre et trois au soleil, ces trois derniers pourront produire au maximum. Les micro-onduleurs ont des garanties de 25 ans. Les marques les plus connues seront Enphase, APSystem voire Hoymiles. Contrairement aux onduleurs centraux, sur les micro-onduleurs, c’est du 230 V qui descend du toit.

Par ou commencer ?

Bien évidemment, la première chose à contrôler, c’est l’exposition de l’endroit où vous souhaitez faire votre installation. La meilleure exposition sera le sud, mais vous pouvez très bien produire si vous êtes sud-est ou sud-ouest et la meilleur inclinaison est de 30° environ.
Il existe une très bonne application pour cela, il s’agit de « La trajectoire du soleil« , disponible sur Android et iPhone. Elle vous donnera les heures d’exposition au soleil par heure de la journée, avec la position actuelle du soleil, mais aussi les plages horaires en été et hiver.
Vérifiez si votre toiture a la place pour une installation solaire.
Grâce à ce site, vous pouvez déjà avoir une estimation de production.

Installation par une entreprise ou soi-même ?

Il faut savoir si vous allez faire votre installation vous-même ou passer par un professionnel, car cela a une importance pour chiffrer votre puissance. Si vous faites votre installation par un professionnel, il y a deux avantages. Le premier sera une prime de l’État (ne vous attendez pas à grand-chose), le second sera la revente totale ou le surplus de votre production à EDF OA. EDF va racheter votre électricité à un tarif fixe pendant 20 ans. Cela dit, depuis février, ce n’est plus très rentable. En effet, pour bien vous expliquer ce qu’il s’est passé, il y a eu une forte hausse pour atteindre 60 cts par kWh en 2009. Depuis, cela a bien chuté, quand on sait que l’on paie entre 15 et 22 cts du kWh, la rentabilité était très bonne. Avant février 2025, nous étions à 10 cts du kWh, et maintenant nous sommes à 4 cts du kWh. Pour bénéficier de tout cela, l’entreprise devra être RGE.
L’avantage de passer par une entreprise, c’est la tranquillité d’avoir un système clé en main à la fin et d’avoir la puissance nécessaire suivant votre besoin. Vous n’aurez aucune démarche administrative à faire, tout sera fait par l’entreprise (demande en mairie, Consuel, déclaration de production auprès de Enedis, on en reparle plus bas).

Comment éviter les arnaques ?

Comme beaucoup d’entre vous, vous avez sûrement déjà reçu des appels pour du démarchage en photovoltaïque. Première chose à savoir : une bonne entreprise ne fait pas de démarchage. Oubliez tout de suite celles qui pratiquent le porte-à-porte. Ce genre de pratique vous promet souvent monts et merveilles, avec des exemples comme :

• Vous ne payerez plus d’électricité, seulement le crédit (Souvent, ils vous font un crédit sans que vous en soyez pleinement conscients).

• Vous allez récupérer la TVA (C’est faux, un particulier ne peut pas récupérer la TVA. Il faut avoir une entreprise pour cela. Certaines entreprises créent une micro-entreprise à votre nom).

• Ils vous font une remise exceptionnelle, genre -3000 €, c’est maintenant ou jamais.

Une fois le contrat signé, ce genre d’entreprise n’attend même pas l’autorisation de la mairie pour commencer l’installation. Il arrive qu’en seulement une semaine, tout soit installé.

La meilleure solution est de chercher une entreprise locale par vous-même, de consulter les avis et de demander plusieurs devis. Pour vous aider, le site « Vite un devis » vous permet de recevoir facilement plusieurs devis d’entreprises de votre secteur. Vous pouvez ensuite les partager sur ce groupe Facebook pour avoir des avis de personnes expérimentées, voire des professionnels du secteur.

Faire sois même.

Si vous êtes prêt à le faire vous-même, il faut prendre en compte la complexité d’une installation. Pour le montage des supports, il faudra monter sur votre toiture, donc vous aurez besoin d’une échelle et d’une échelle de toit, ainsi que d’un système de sécurité (anti-chute, harnais, amortisseur de chute, etc.). Pour la fixation des crochets et le montage des rails, ils devront être vissés dans les chevrons de votre toiture. Cela implique des découpes de vos ardoises, avec l’ajout de plaques de zinc ou de légères modifications pour les toits en tuiles, etc. Tout cela devra être bien réalisé pour éviter toute infiltration d’eau.

Il faut également prendre en compte que les panneaux sont encombrants (pour rappel, leurs dimensions sont de 1134 mm x 1994 mm) et que le poids des panneaux de 500 Wc atteint 27 kg. Il vous faudra aussi des connaissances en électricité.

Côté administratif, il sera nécessaire de faire une demande en mairie, d’obtenir un Consuel (ce qui peut s’avérer complexe), et de déclarer votre installation à Enedis.

Les démarches administrative

Depuis le début, je vous parle des démarches administratives. Il y a plusieurs choses à faire avant et après l’installation.

Déclaration préalable de constructions et travaux non soumis à permis de construire (CERFA 16702*01) :
C’est une déclaration à déposer en mairie. Elle n’est pas toujours obligatoire, comme pour un kit au sol, mais pour une installation à plus de 1,8 m, elle l’est. Donc, pour une installation sur toiture, il faudra la remplir. Pour cela, vous devrez fournir diverses photos et des plans avant / après. Pour m’aider, j’ai utilisé cette vidéo. La mairie a un mois pour vous répondre. Passé ce délai, vous pouvez considérer que la demande n’a pas été refusée.

Une fois l’installation terminée, il faudra retourner un document de déclaration de fin de travaux, qui vous sera remis lors de la validation.

Le Consuel :
Cette démarche n’est pas gratuite, il faudra compter environ 180 €. Pour les kits plug-and-play, le Consuel n’est pas nécessaire, mais il sera obligatoire pour une installation supérieure à 3 kWc en sortie de vos onduleurs. La demande ne sera pas facile à remplir et vous demandera des informations très détaillées sur votre installation. Il vous faudra aussi fournir un schéma électrique de votre modification, dont nous reparlerons plus bas. Pour vous aider, voici un lien.

Déclaration Enedis :
Vous devez informer Enedis que vous êtes producteur d’électricité. Pour cela, il faut vous rendre sur le site d’Enedis, aller dans la section « Ma production » et « Déclarer vos panneaux photovoltaïques« . Cette vidéo pourra vous être utile.

Mon installation

Après environ cinq mois de collecte d’informations, je me lance enfin dans mon projet. J’ai profité de cette période hivernale pour étudier l’exposition de ma toiture. En hiver, le soleil étant plus bas, et avec des arbres présents sur la propriété voisine, une partie de mon toit est ombragée le matin, mais devient entièrement ensoleillée en fin de matinée. En avril, cette ombre matinale disparaît presque totalement.

Initialement, j’avais prévu d’opter pour un onduleur central. Cependant, après cette période d’observation, j’ai finalement décidé de me tourner vers des micro-onduleurs.

J’ai pris les mesures de mon toit, ce qui me permet d’installer jusqu’à sept panneaux de 500 Wc. Mon idée de départ était d’installer des panneaux à la fois sur la maison et sur le garage, pour un total de 11 panneaux. Mais j’ai choisi de commencer plus modestement afin de maximiser l’autoconsommation.

J’ai donc réalisé un plan (le tableau comporte des espaces vides car il a été conçu pour l’installation complète). Le câblage diffère légèrement au niveau du TGBT, car celui-ci étant situé juste à côté de mon nouveau tableau, je n’ai pas installé de disjoncteur. Je me suis directement connecté au bornier du tableau. Un disjoncteur est obligatoire si le tableau se trouve à une plus grande distance. Il aurait été préférable d’en installer un, mais mon tableau principal est déjà complet.

Enfin, il est important d’ajouter la mise à la terre. Les deux rails devront être reliés par un fil de 6 mm² jusqu’au tableau. Lors du montage des panneaux pour une bonne mise à la terre avec votre kit de montage et les panneaux, vous aurez des « Terra grif« .

Je réalise ensuite mon calepinage pour estimer le coût des supports. Pour cela, je me rends sur le site de K2 Base. Après avoir créé un compte et renseigné toutes les informations nécessaires, j’obtiens un schéma d’implantation.

Il est toutefois important de vérifier ce schéma attentivement, car l’une des brides de raccordement se trouvait initialement sur un crochet. Disposant de cinq barres de 3,65 m, nous avons raccourci celle du milieu de 30 cm. Ainsi, au lieu de couper la dernière à 80 cm, nous l’avons ajustée à 110 cm. Cette modification à permis de décaler la position de la bride.

Pour en revenir aux micro-onduleurs (MO), j’ai le choix entre deux marques mentionnées plus haut : APSystems et Enphase. J’ai eu la chance de trouver une entreprise de vente de matériel, AvelHeol, située à seulement 45 minutes de chez moi, qui propose les produits APSystems. Au début, ils n’avaient pas les panneaux que je souhaitais, les DMECG de 500 Wc. Mais en continuant à mûrir mon projet, AvelHeol a finalement eu en stock tout le matériel nécessaire.

En ce qui concerne l’achat de votre matériel, je vous conseille de privilégier un revendeur proche de chez vous, idéalement avec plusieurs années d’existence.

Un critère important pour moi est l’intégration à ma domotique. L’objectif était de pouvoir connecter mon système solaire à Home Assistant. Pour APSystems, un plugin existe pour la version Plug and Play, et un autre est disponible sur HACS. Toutefois, ce plugin est fait pour la passerelle ECU-B. Or, pour une solution complète, l’ECU-C est préférable. Le problème, c’est que le plugin HACS peut rendre l’ECU-C complètement inaccessible après un certain temps.

Autre point concernant les APSystems : le micro-onduleur DS3 est conçu pour raccorder deux panneaux. Étant donné que je souhaite installer sept panneaux, cela signifie que l’un des micro-onduleurs serait sous-utilisé avec un seul panneau.

Il me reste donc Enphase. Ici, aucun souci pour l’intégration avec Home Assistant : une intégration officielle existe, ainsi que deux autres proposées par la communauté. L’inconvénient principal reste le prix des micro-onduleurs.

Un APSystems DS3, capable de connecter deux panneaux, coûte environ 200 €. Pour Enphase, chaque panneau nécessite un micro-onduleur, et il faut compter environ 230 € par unité. Pour faire une analogie : Enphase, c’est comme Synology, une solution premium et verrouillée, tandis que APSystems serait plutôt l’équivalent de Qnap, plus flexible. D’ailleurs, Enphase commence à restreindre les auto-installations : un message sur leurs applications indique qu’il sera bientôt impossible d’activer des micro-onduleurs achetés chez des vendeurs non agréés. Et là se pose un problème : leur liste de revendeurs agréés en France est très restreinte, et aucun site de vente en ligne n’y figure.

En résumé, j’ai décidé de partir sur sept panneaux DMECG de 500 Wc avec sept micro-onduleurs Enphase IQ8P, ainsi qu’un kit de fixation K2 System. Une fois le dossier déposé en mairie, j’ai obtenu le feu vert en seulement deux semaines.

Pour les panneaux et les rails, j’ai passé commande chez AvelHeol, puis je me suis rendu à leur entrepôt pour récupérer le matériel. Pour les équipements Enphase, j’ai également choisi une entreprise locale : Yesss Électrique. Bien que cette enseigne soit principalement destinée aux professionnels, elle vend également aux particuliers.

Yesss Électrique possède des agences partout en France. C’est une entreprise de longue date, et ayant l’habitude de travailler avec eux dans mon domaine professionnel, je connais leur sérieux et leur professionnalisme.

Pour constituer un kit Enphase, vous aurez besoin de :

• Le nombre de MO nécessaire pour votre installation (Il faudra voir quel modéle IQ8 il conviendra à votre panneau) ;
• Un Q-relai (Son rôle sera de couper la production en cas de coupure électrique du réseau) ;
• Un Q-Cable (Il va servir à relier tous les MO entre eux. Quand vous commander, la quantité à indiquer et le nombre de MO à relier) ;
• Une passerelle Q-Gateway. Il existe 2 versions, la Envoy-S standard qui possède qu’un seule prince tore pour le suivi de production plus destiné à la revente total. La Envoy-S metered qui possède 2 pinces. Nous avons ainsi un suivi de production et de consommation de la maison elle est aussi prévu pour la gestion des batteries. Je suis parti sur cette dernière.

Le montage peut commencer

Pour la partie des crochets, j’ai fait appel à un couvreur professionnel. Comme nous allons intervenir directement sur l’étanchéité de la toiture, je préfère que ce soit réalisé correctement. Si vous êtes à l’aise avec cette tâche, voici une vidéo qui montre la procédure sur une toiture en ardoise.

En attendant la date de pose des crochets, je me suis occupé de la partie tableau dédiée au photovoltaïque. Une extension a été nécessaire pour intégrer ce nouveau tableau. On y trouve la passerelle et le Q-relai.

Le jour J de la pose des crochets est enfin arrivé. Il a fallu environ quatre heures au couvreur pour installer les 15 crochets. De plus, la sortie de la VMC se trouvant sous les panneaux, nous avons dû la déplacer.

Nous avons également ajouté une chatière pour permettre le passage du câble jusqu’au grenier (non encore installée sur la photo).

Pour la partie montage des rails, j’ai réalisé cela avec mon père. En soi, le montage est assez simple, mais les choses se compliquent lorsqu’on travaille sur un toit avec une pente de 45° et qu’on n’est pas habitué à adopter certaines positions sur de petites échelles.

À la fin de la journée, tous les rails étaient installés.

À l’issue de cette journée, il restait à installer les micro-onduleurs, à connecter les câbles entre eux, et à poser les panneaux. Cependant, une grande fatigue musculaire s’est installée, et travailler en hauteur devenait compliqué.
Nous avions prévu de poser les panneaux le dimanche, mais cela n’a pas été possible. J’ai donc décidé de suspendre le chantier et d’attendre le lundi. J’avais initialement contacté une entreprise de ma ville pour réaliser l’installation, mais elle ne travaillait pas avec Enphase toute fois il pouvait tout de même me faire la pause. Après un appel et une visite, le rendez-vous est pris pour finir l’installation.

Avant le montage des micros-onduleurs, il faut récupérer tous les codes à barre et les placer sur une feuille dans l’ordre qu’ils seront monté. Cela sera utile lors de la configuration du système.
Voici les IQ8P de chez Enphase.

Une semaine plus tard, en seulement 1h30, tout était installé.

 

Lors de l’installation du tableau électrique, j’ai fait passer un câble 3G6 mm² jusqu’au grenier, qui ressort par une chatière ajoutée. Afin de limiter les entrées d’air frais, j’ai modélisé et imprimé en 3D un cache.

Le système est maintenant prêt à démarrer, et tout se fait via l’application Enphase Toolkit. Plusieurs étapes sont nécessaires : la première consiste à scanner les codes-barres des micro-onduleurs (MO), puis ceux du Q-Relai et de la passerelle.

Le système procède ensuite à la mise à jour de tous les composants, vérifie si les pinces de mesure sont correctement installées, et effectue divers tests.

Après environ 45 minutes, tout est opérationnel, et vous pouvez enfin profiter de votre énergie solaire. Vous pourrez maintenant installater l’application Enlighten pour votre suivi.

Et maintenant ?

Il faut faire votre demande de Consuel, voici un exemple de schéma unifilaire qu’il faudra fournir.

Il est également nécessaire d’ajouter divers autocollants sur vos tableaux et disjoncteurs. Vous pouvez acheter une planche d’autocollants à ce lien, qui indique également où les placer.

Ensuite, vous devrez remplir votre déclaration de fin de travaux et déclarer votre installation auprès d’Enedis.

Il va falloir changer nos habitudes de consommation pour maximiser l’utilisation de l’énergie solaire. Par exemple, nous avions l’habitude de lancer les machines à laver le linge tôt le matin. Désormais, nous les décalerons légèrement pour attendre que le soleil soit bien présent, surtout pendant le mois d’avril.

Prenons l’exemple du vendredi 9 mai : j’ai pu lancer une machine à laver dès 9 h, avec une consommation d’environ 1 000 W. Ensuite, j’ai fait tourner le sèche-linge, qui consomme 2 200 W, à partir de 10 h 15, alors que la production solaire atteignait 2 500 W.

Fini également les cycles de lave-vaisselle la nuit, en heures creuses. Désormais, nous le faisons plutôt sur l’heure du midi, en utilisant le programme « Quick and Clean », qui chauffe à 60°C. Ce programme consomme davantage, mais comme il utilise l’énergie solaire, ce n’est pas un problème. En plus, il est plus rapide, ce qui permet de libérer la puissance de production pour d’autres appareils plus rapidement.

Il faudra aussi modifier votre assurance habitation pour prendre en compte vos panneaux. De mon côté cela m’a fait un sur plus de 20€ à l’année. Etant sur une ancienne offre j’ai du changer mais celle-ci inclus aussi maintenant mes clôtures et portail.

Que faire quand on a plus besoin de ce que l’on produit ?

Il peut être difficile de tout consommer, surtout lorsque la production solaire varie rapidement. Par exemple, au moindre éclaircissement, je peux passer de 1 000 W à 3 000 W.

Sur une installation en autoconsommation sans revente, le surplus de production part sur le réseau gratuitement, avec une limite de 6 kVA. Bien sûr, ce n’est pas ce que l’on souhaite. Pour éviter cela, il existe le routeur solaire. Son rôle est de rediriger le surplus d’énergie vers un équipement résistif, et l’un des plus courants est le ballon d’eau chaude.

Mon cumulus est un modèle de 300 L avec une résistance de 3 000 W, qui chauffe en heures creuses. Il se déclenche à 22 h 30 pour chauffer, puis relance des cycles toutes les 30 minutes jusqu’à 6 h 30 pour maintenir la température.

Le routeur solaire va envoyer uniquement l’excédent d’énergie dans le cumulus. Par exemple, si je produis 2 500 W et que ma maison consomme en veille 200 W, sans routeur, en activant mon ballon en marche forcée, celui-ci va consommer 3 000 W. Nous utiliserons donc les 2 300 W de production solaire (2 500 W – 200 W) et les 700 W restants seront prélevés sur le réseau.

Mais avec le routeur solaire installé sur le cumulus et son relais SSR, l’énergie excédentaire est automatiquement envoyée dans la résistance. En reprenant l’exemple, le routeur détectera le surplus de 2 300 W et enverra cette puissance directement au ballon, sans puiser sur le réseau. Le ballon prendra plus de temps pour chauffer, mais il utilisera uniquement l’énergie solaire.

Voici un exemple concret :

• En bleu, ma production solaire.

• En orange, ma consommation.

• En gris, l’énergie prélevée sur le réseau.

Sur la première image (avant l’installation du routeur), on voit que le ballon se déclenche à 22 h 30. Sur la seconde image (après installation), on remarque que j’ai consommé toute la production en début de journée, mais que j’ai renvoyé du surplus sur le réseau l’après-midi.

Pour optimiser cela et garantir de l’eau chaude pour les douches du lendemain, j’ai configuré une différence de 5°C sur la température du cumulus. Ainsi, il se réchauffe en journée en utilisant l’excédent solaire, ce qui explique les pics de consommation orange dans l’après-midi.

Un routeur solaire est le plus souvent une solution DIY , bien que quelques fabricants en proposent, mais à des tarifs très élevés. Parmi les solutions DIY, on trouve notamment : le MSunPV, le F1ATB, le Yasolr, et bien d’autres.

Après un long moment d’hésitation, j’ai finalement opté pour le MSunPV. J’ai été séduit par le fait qu’il soit vendu déjà monté (même si le DIY ne me dérange pas), mais surtout par sa finition compacte avec un boîtier conçu pour être monté sur rail DIN.

L’intégration à Home Assistant était également essentielle pour moi, tous ces modèles le permettent.

Voici mon installation terminée. Côté cumulus, on peut remarquer l’ajout du relais SSR avec son large dissipateur thermique.

Si vous souhaitez plus de détails sur mon installation, vous pouvez consulter ce lien vers le forum de MSunPV.

Le routeur ne se limite pas uniquement au ballon d’eau chaude. En effet, j’ai opté pour un modèle à quatre sorties. Par exemple, si mon cumulus est déjà chaud en hiver, l’excédent d’énergie pourra être redirigé vers un radiateur dans la maison pour fournir un appoint de chauffage. Ce radiateur ne doit cependant pas être électronique.

Si vous avez une piscine, il est également possible de l’utiliser pour chauffer l’eau.

Voici mon schéma de câblage :
Pour les modes de marche forcée, j’ai conservé mon contacteur Jour/Nuit, qui est piloté par un relais Zigbee. En hiver, il sera également possible de programmer sur le routeur une plage horaire pour que le cumulus fonctionne en heures creuses si la production solaire est insuffisante.

Ici nous avons l’interface web du routeur.

Que faire une fois que toute l’énergie produite est consommée et que le cumulus est chaud ?

1. La batterie virtuelle

Une solution consiste à utiliser une batterie virtuelle. Votre surplus d’énergie est stocké de manière illimitée, et lorsque le soleil n’est plus au rendez-vous, vous utilisez ce que vous avez envoyé.

Cependant, les avantages de cette option sont mitigés. Par exemple, chez Urban Solar, il faut débourser 299 € pour s’inscrire, et ils deviennent alors votre fournisseur d’électricité. De mon côté, j’ai remarqué que leur tarif heures creuses / heures pleines est plus avantageux que celui de mon fournisseur actuel.
Toutefois, je n’ai pas encore trouvé de retours d’expérience convaincants. D’après ce que j’ai pu lire, cette solution semble plus rentable pour de grandes installations, comme 6 kWc ou plus.

2. L’autoconsommation collective

Il est également possible de vendre votre surplus d’énergie à vos voisins dans un rayon de 2 km. Cette solution est souvent gérée par des organismes.
En pratique, sans cette option, votre surplus part sur le réseau et peut être consommé par vos voisins, qui le paient au prix de leur contrat. Avec l’autoconsommation collective, vous pouvez leur revendre ce surplus à un tarif plus avantageux. Vous trouverez plus d’informations sur ce système chez SiSol.

Cependant, cette solution présente aussi des risques. En fonction de la demande, le tarif peut devenir négatif. Cela signifie que vous pourriez payer pour envoyer votre surplus sur le réseau. Dans ce cas, il est préférable de brider votre onduleur pour éviter ces frais.

3. Revente à EDF OA

Si vous êtes passé par une entreprise, il sera possible de faire la revente. Le règlement aura lieu une fois par an.

Changer de fournisseur

Le changement de fournisseur pourrait faire partie des ajustements à envisager après l’installation. En effet, de nombreuses personnes optent pour l’offre Tempo d’EDF. Cependant, il faut être vigilant aux 21 jours rouges, où les tarifs sont plus élevés.

Il est donc essentiel de bien calculer votre consommation et votre production d’électricité. Si vous disposez d’un second système de chauffage, cette offre pourrait être rentable.

La domotique

Il était primordial pour moi de pouvoir tout intégrer à Home Assistant. Pour Enphase, j’ai utilisé cette intégration, qui offre une actualisation presque en temps réel, contrairement à celle intégrée nativement à Home Assistant. Pour le routeur, j’ai utilisé cette intégration.

Après un peu de travail de mise en page, voici le résultat : vous pouvez voir l’effet du routeur, avec le graphique orange qui représente la consommation réseau, maintenue à 0 W. En haut à droite, la section production affiche 3 193 W avec une production totale de 10 697 Wh depuis le début de la journée. Juste en dessous, le routeur montre qu’il envoie 2 915 W vers le cumulus. Sur la seconde image, il s’agit du tableau de bord énergétique de Home Assistant.

Afin de rendre les choses plus faciles pour tout le monde, sur mon petit écran Home Assistant (retrouvez mon article ici), j’ai créé un tableau de bord dédié à la partie Solaire.

Les tuiles pour le lave-linge, le lave-vaisselle et le sèche-linge permettent de savoir quand la production est suffisante pour démarrer une machine. L’information « Dispo » possède un timer. En effet, si une éclaircie survient, tout passerait au vert. Pour pallier cela, j’ai mis une durée de 5 minutes.

Chaque appareil ne consomme pas la même chose. Pour la machine à laver, c’est 1000 W. Si la production est supérieure à 1000 W pendant 5 minutes, cela passe au vert, ce qui signifie que la production est suffisamment stable. Pour le lave-vaisselle, c’est 1500 W, il est en jaune, car c’est limite, j’ai seulement 1461 W de disponibles. Et pour le sèche-linge, c’est 2200 W, il est donc en rouge.
La consommation de la maison est élevée, car elle prend en compte le routeur. Les tuiles se basent sur la disponibilité nette sans le routeur, sinon tout resterait en rouge. Comme le routeur s’adapte à la consommation de la maison et de la production pour être toujours à 0w, cela n’empêche pas de démarrer une machine à laver.
J’ai aussi fait un petit écran sous ESPHome pour des infos plus techniques.

Conclusion

Je ne peux pour le moment vous informer sur l’effet positif, mon installation a 3 semaines. Mais quand on voit que j’arrive à atteindre 50% de consommation solaire sur une journée, c’est très encourageant. Si vous souhaitez vous lancer, il va falloir faire des recherches supplémentaires de votre côté. L’article avait pour but de vous partager les bases, mais il y aura différents paramètres à prendre en compte selon vos besoins, vos habitudes, et ce que vous avez au niveau des équipements électriques…

Le coût global de mon installation est de 4500€, ce qui comprend absolument tout (matériel solaire, électrique, équipement de sécurité, Consuel et routeur).

The Zimaboard 2 Single Board Server Review – The Best Yet?

In an increasingly saturated market of single-board computers and compact servers, the ZimaBoard 2 arrives with a clear goal: to offer an affordable, x86-powered, DIY-friendly alternative that bridges the gap between embedded systems and full-blown home servers. Developed by IceWhale, a brand that has already seen crowdfunding success with products like the original ZimaBoard, ZimaBlade, and ZimaCube, the ZimaBoard 2 aims to refine the company’s mission of delivering low-power, highly customizable devices for tinkerers, creators, and homelab enthusiasts. At its core, the ZimaBoard 2 is designed for users who want flexibility without complexity—whether that’s spinning up a lightweight virtualization platform, building a smart home hub, deploying a personal cloud, or running a local media server with minimal noise and energy consumption.

Unlike consumer-grade NAS systems or ARM-based boards, ZimaBoard 2 taps into the x86 ecosystem, offering broader OS compatibility and performance benefits while maintaining a compact, passively cooled footprint. This review explores the hardware, thermal and network performance, and software environment of the ZimaBoard 2, evaluating where it fits in the broader landscape of edge computing and personal infrastructure. As with previous IceWhale launches, this unit is being released initially through crowdfunding—a factor that calls for cautious optimism. Still, with a track record of fulfilling past campaigns, IceWhale appears confident in ZimaBoard 2’s readiness. Whether that confidence is justified, and whether the board truly earns its place in a crowded DIY server landscape, is what we’ll determine over the course of this review.

Zimaboard 2 Review – Quick Conclusion

The ZimaBoard 2 is a compact, x86-based single board server that strikes a balance between flexibility, efficiency, and affordability. It offers solid performance for its size, thanks to an Intel N150 processor, dual 2.5GbE ports, and a PCIe 3.0 x4 slot for meaningful expansion, making it suitable for tasks like media serving, light virtualization, and home automation. However, limitations such as non-upgradable 8GB RAM, slow onboard eMMC storage, and reliance on passive cooling require careful consideration for more demanding workloads.

Zimaboard 2 Review – Design and Hardware

The physical build of the ZimaBoard 2 continues IceWhale’s trend of delivering thoughtfully designed hardware. The full aluminum enclosure gives the board a sturdy, premium feel, while also serving as its main cooling surface. Every port is clearly labeled, and the board layout is practical and accessible.

The PCIe slot includes a pre-cut section to accommodate longer cards, allowing for flexibility even in this small form factor. IceWhale also includes eco-friendly packaging, a detail that reflects both brand identity and attention to user experience. A cardboard insert allows users to hold the board upright alongside drives, useful for initial setup before a case is selected.

Optional accessories like a SATA adapter board with combined data/power connectors and third-party-compatible drive cages help complete the DIY experience. However, there are some practical limitations to consider: the soldered RAM means users must carefully plan for memory demands, and the internal storage, while functional, will not satisfy users looking for fast OS performance.

At the core of the ZimaBoard 2 is the Intel N150 processor, part of Intel’s Twin Lake architecture, offering four cores with a base clock that boosts up to 3.6GHz. This chip represents a significant step forward compared to the Celeron N3450 used in the original ZimaBoard, delivering better single-thread and multi-thread performance while maintaining a low 6W TDP.

Complementing the CPU is 8GB of LPDDR5x memory clocked at 4800MHz. While the use of fast memory is a welcome improvement, the limitation lies in its soldered nature—users cannot expand beyond this capacity.

This decision may be acceptable for light workloads such as running a Plex server, Docker containers, or Home Assistant, but it could become a bottleneck for users planning to run multiple VMs or resource-heavy services. The N150 CPU does support hardware virtualization and Intel AES-NI, which is essential for tasks like encrypted storage or virtual machine deployment.

In testing scenarios, the CPU delivered solid performance across typical tasks, and managed to keep up during multi-tasked environments with multiple services active. However, users with ambitions for more demanding applications will need to balance those expectations against the non-upgradable memory ceiling.

ZimaBoard 2 comes with 32GB of onboard eMMC storage, a choice that is both practical and limiting. This eMMC module is soldered to the board and is intended to house ZimaOS out of the box, giving users a ready-to-use system upon first boot. While this inclusion lowers the barrier to entry and simplifies setup for beginners, it presents performance limitations and a lack of flexibility. In testing, write speeds hovered around 35MB/s during mixed I/O operations, which is noticeably slow for tasks that involve frequent read/write cycles.

Moreover, should a user opt to install a different OS—such as TrueNAS SCALE, Proxmox, or Unraid—they would either overwrite the bundled ZimaOS or need to boot from an external USB or PCIe-based drive. Since the internal storage is neither M.2 nor socketed, it lacks the speed and modularity enthusiasts often seek in modern setups. As a result, users planning to use ZimaBoard 2 as a primary virtualization or storage server are better off supplementing it with faster storage via USB 3.1, SATA, or the PCIe slot for booting alternative OS environments. This caveat underscores a recurring theme with ZimaBoard 2: it’s well-positioned for entry-level use but requires external upgrades for more ambitious workflows.

One of the ZimaBoard 2’s most compelling features is its inclusion of two SATA 3.0 ports alongside a full PCIe 3.0 x4 slot. This greatly expands the device’s potential beyond typical SBCs, offering users a reliable way to build custom NAS setups, integrate high-speed NVMe storage, or even install networking and accelerator cards. During testing, a Synology combo card featuring two M.2 NVMe slots and a 10GbE Ethernet port was installed in the PCIe slot. The board successfully recognized all interfaces, demonstrating full PCIe compatibility and allowing throughput measurements to confirm the system could push high-bandwidth traffic.

With up to 4GB/s of bandwidth over PCIe, users can install expansion cards for fast storage, additional networking, or even compute offloading—although the small form factor means thermal and power considerations become important quickly. The SATA ports, while standard in speed, proved perfectly functional for connecting 2.5″ SSDs or traditional HDDs. IceWhale’s own accessories, like SATA power adapters and drive cages, help streamline this process, though third-party solutions work just as well.

For users aiming to transform this board into a flexible micro-server, this PCIe slot is a gateway to many possibilities and a key reason ZimaBoard 2 stands out in its category.

In terms of networking, the ZimaBoard 2 comes equipped with two 2.5GbE Ethernet ports, both powered by Intel chipsets—a choice that emphasizes reliability and driver compatibility across various operating systems. These ports are more than just a checkbox feature; they performed reliably under load and achieved full link saturation during file transfer tests and when used in conjunction with PCIe expansion.

In more advanced setups, users can configure bonding or load balancing to maximize throughput or redundancy. Additionally, there are two USB 3.1 ports for attaching external drives, peripherals, or USB-bootable OS images.

The inclusion of a Mini DisplayPort 1.2 allows for 4K video output at 60Hz, which is useful for users who want to use the board as a lightweight desktop or for initial OS installation and diagnostics—though it does require an adapter to convert to standard HDMI. Notably absent is built-in Wi-Fi or Bluetooth, which aligns with its target audience of wired-first home labs and embedded installations. Overall, ZimaBoard 2 offers a well-rounded set of connectivity options that exceed expectations for its size, with the dual 2.5GbE ports making it particularly attractive for networking-focused use cases like firewalls, proxies, or containerized gateways.

Thermal management on the ZimaBoard 2 is entirely passive, with the aluminum enclosure doubling as a heatsink to dissipate heat away from the CPU and other key components. This fanless approach results in completely silent operation, which is ideal for home or office environments where noise is a concern.

However, the trade-off is that the board’s temperature will steadily rise over time, especially in enclosed cases or cabinets with poor airflow. During idle operation, with minimal system load and attached drives in standby, temperatures hovered around 50°C after an hour, increasing slightly to 52–54°C over a 24-hour window.

Under heavier usage—including Plex playback, VM activity, active networking, and full PCIe slot utilization—the system remained thermally stable but showed significant heat buildup. Power consumption in these high-usage scenarios peaked at approximately 39–40W, which is quite efficient given the workload.

Still, users planning to run the board continuously under load are strongly encouraged to introduce active airflow or leave the system in a well-ventilated space. The all-metal build is a clever and minimalist solution, but it has practical limitations that users need to plan for—especially if operating in warmer environments or planning to enclose the unit in a tight chassis.

When put through real-world workloads, the ZimaBoard 2 delivered performance that largely aligned with its specs and design goals. File transfers over the onboard 2.5GbE interfaces reached full saturation in controlled conditions, proving the CPU and I/O subsystems are capable of pushing maximum throughput without significant bottlenecks. PCIe expansion further unlocked performance potential—especially with the Synology combo card, where simultaneous NVMe and 10GbE performance were tested. While NVMe read speeds reached up to 1.6GB/s, write speeds hovered around 500–700MB/s depending on traffic from the 10GbE port.

These variances are expected, given shared PCIe lanes and bandwidth contention, but overall results were respectable. Multimedia performance was also acceptable, with Plex running smoothly and able to stream and scrape metadata while supporting light VM usage concurrently.

In these scenarios, RAM utilization climbed past 50% and CPU usage approached 100%, but the board remained operational and responsive. It’s clear that ZimaBoard 2 is well-suited to low-to-moderate workloads, and can punch above its weight with strategic expansion. However, pushing it into more demanding territory—like simultaneous virtualization, AI inferencing, or high-speed file serving across multiple interfaces—will begin to test its limits.

The lack of active cooling makes thermal planning essential for any serious workload. But overall, the ZimaBoard 2 feels polished and reliable, with a design philosophy that caters well to its core audience of DIY server builders and edge compute experimenters.

Zimaboard 2 Review – Software

ZimaBoard 2 ships with ZimaOS, a custom-built operating system from IceWhale that is based on CasaOS—a lightweight, open-source platform designed for simplicity and ease of deployment. ZimaOS retains the core principles of CasaOS but adds refinements tailored to the Zima ecosystem, particularly features that emerged during development of the more powerful ZimaCube. The out-of-the-box experience is beginner-friendly, offering an intuitive web dashboard called “LaunchPad,” which centralizes access to installed applications, system controls, and file management.

ZimaOS is pre-installed on the board’s eMMC storage, enabling immediate setup without requiring users to flash a drive or download additional software. Despite the modest resources of the ZimaBoard 2, the OS performs responsively, even with several services running in parallel. The interface is clean, albeit minimalistic, focusing on usability over deep customization.

For users who are new to home servers or Docker deployments, the learning curve is surprisingly gentle. Though it lacks some of the granularity of more established platforms like OpenMediaVault or TrueNAS, it’s clear that IceWhale has designed ZimaOS to get users up and running quickly without sacrificing key functionality.

One of the more distinctive features of ZimaOS is its integrated App Store, which acts as a curated hub for Docker-based applications. Unlike traditional NAS interfaces that require command-line Docker commands or extensive Portainer configuration, ZimaOS simplifies deployment through one-click installation and automated environment setups.

Popular applications like Plex, Jellyfin, Stable Diffusion, and more are available by default, with the option to add third-party sources for broader container variety. Behind the scenes, the system leverages containerization frameworks to handle resource isolation and volume mappings, but much of this complexity is hidden from the end user.

Application setup is further eased by pre-configured defaults such as port assignments, directory structures, and even PUID/PGID settings, reducing friction for non-technical users. For those with more experience, ZimaOS still allows you to tweak or override these settings manually. Notably, ZimaOS also includes a basic virtualization interface that supports downloading and running lightweight VMs using prebuilt images.

While this feature is better suited to the higher-specced ZimaCube due to memory and cooling constraints, its presence on the ZimaBoard 2 is still a nice touch and shows that the OS is aiming to grow into a more comprehensive platform. Overall, the application and container ecosystem here punches above its weight, especially considering the resource constraints of the board itself.

In terms of storage and file sharing, ZimaOS delivers a capable if somewhat minimal feature set that prioritizes simplicity over enterprise-style depth. Users can create RAID groups—a new feature compared to earlier CasaOS iterations—manage individual drives, and set up file-level sharing using standard protocols like SMB.

The file manager, accessible through the main dashboard, allows for browsing, copying, and sharing content in a familiar web-based interface. Integration with IceWhale’s own client tool enables a peer-to-peer feature called “peerdrop,” which links multiple Zima-based systems or client devices (like phones and laptops) for rapid syncing and data exchange.

This is especially useful for users who want an easy method to upload media, backup devices, or move files between multiple systems on a local network. Remote access can be enabled through a simple relay-based mechanism, which generates shareable links for specific files or folders, complete with read/write controls. While more advanced access control, encryption, or user quotas are not present in this build, the essentials for home or small office use are here and function as expected.

Cloud integration is also available, allowing the addition of third-party storage such as Google Drive or Dropbox for backup or syncing purposes. Though ZimaOS doesn’t try to replace full-fledged NAS operating systems in terms of depth, it successfully delivers the features most users will need, and its lightweight design ensures responsiveness even on modest hardware like the ZimaBoard 2.

Zimaboard 2 Review – Conclusion & Verdict

The ZimaBoard 2 is a competent and thoughtfully assembled single-board server that builds meaningfully on IceWhale’s earlier efforts, especially the original ZimaBoard and the ZimaBlade. Its design clearly targets users who want more flexibility and performance than traditional ARM-based boards can offer, but who also value power efficiency, silence, and a small footprint. The use of an Intel N150 CPU, 8GB of LPDDR5x memory, dual 2.5GbE ports, and a PCIe 3.0 x4 slot makes it viable for a variety of home server roles—from basic NAS and smart home coordination to lightweight container hosting and local media streaming. Features like onboard SATA, USB 3.1, and a DisplayPort connection further add to its utility. However, there are hardware limitations that may affect long-term suitability for advanced deployments. The soldered RAM cannot be upgraded, and the internal eMMC storage, while useful for initial setup, is too slow for OS-level responsiveness in more demanding use cases. Passive cooling, while appreciated for silence, also imposes some thermal limitations depending on the deployment environment.

On the software side, ZimaOS offers a decent out-of-the-box experience that caters to users with minimal technical background. It handles core tasks like application deployment, file sharing, and system monitoring without requiring advanced configuration, and its Docker-based App Store simplifies access to popular tools. For more experienced users, the system supports third-party OS installation, which is likely how many will ultimately use the ZimaBoard 2. Still, as a bundled solution, ZimaOS has matured significantly and now presents itself as a lightweight, capable, and non-intrusive platform for those who prefer to get started immediately. In the broader context of DIY server hardware, ZimaBoard 2 occupies a middle ground: more powerful and modular than Raspberry Pi-class systems, yet more constrained than full x86 mini PCs or enthusiast-grade NAS hardware. For those who understand and accept these trade-offs, and are willing to plan around its limitations, the ZimaBoard 2 offers a reliable and flexible foundation for compact, energy-efficient computing at the edge.

Synology Beestation Plus 8TB Revealed and Detailed

Synology has unveiled the BeeStation Plus (BST170-8T) in their pre-Computex build up (alongside an early reveal back in Jan 2025 at CES/Pepcom), the latest addition to its growing portfolio of personal cloud storage solutions aimed at everyday users. Building on the success of the original BeeStation (BST150-4T), the Plus model directly addresses feedback from users who wanted greater capacity, faster performance, and more versatile applications—without the steep learning curve of traditional NAS systems. This one-bay device ships pre-populated with an 8TB Synology HAT3310 hard drive (7200 RPM), powered by a quad-core Intel Celeron J4125 processor and 4GB of non-upgradable DDR4 memory. The combination is notable because it brings x86-class processing and hardware transcoding support to an ultra-simplified setup—something virtually unheard of in this form factor. With its out-of-the-box readiness, cloud-linked setup process, and focus on seamless user experience, BeeStation Plus is designed for those seeking to move away from Google Drive, iCloud, and Dropbox subscriptions, offering complete local control of data without compromising on usability. Features such as AI-driven photo management, native mobile apps, and Plex Media Server support are now included, making this device far more than just cold storage. For individuals and families looking to centralize their backups, photos, videos, and personal files in a user-friendly ecosystem—without paying monthly cloud fees—Synology positions the BeeStation Plus as an appealing middle ground between cloud services and more complex NAS platforms like the DiskStation DS224+.

Synology Beestation Plus 8TB – Who Is This For?

The BeeStation Plus is designed with a clear goal: to serve individuals, families, and small teams who want private, centralized storage without the barriers that typically come with managing a traditional NAS. It’s aimed at users who are familiar with cloud platforms like Google Drive, Dropbox, or iCloud, but want to move away from recurring subscription fees and the privacy concerns associated with third-party cloud storage. For many, the idea of hosting data locally remains appealing—yet the complexity of DSM-based Synology systems can be overwhelming. The BeeStation Plus sidesteps that entirely by offering a plug-and-play experience: no drive installation, no volume configuration, no knowledge of RAID, and no need to navigate DSM’s enterprise-leaning control panels.

Instead of DSM, BeeStation Plus runs a simplified, task-oriented operating system that emphasizes automation and immediacy. Setup is handled via a QR code and cloud-linked sign-in process using your existing Apple or Google account. Within minutes, users can begin backing up photos, syncing cloud drives, or transferring personal data using intuitive applications like BeePhotos and BeeFiles. Notably, BeePhotos offers local AI processing for face recognition and subject categorization—no data is sent to the cloud, and everything runs on-device using the integrated GPU in the Intel Celeron chip. These features mimic what users expect from modern photo cloud services, but with full local ownership.

Where the DiskStation platform caters to power users—with capabilities like multi-tiered storage pools, user-group policies, virtualization, Docker containers, and dual-LAN failover—BeeStation Plus avoids this complexity altogether. While some may view it as limiting, Synology has correctly identified a growing segment of mainstream users who simply want a secure, reliable, and easy-to-manage storage hub for their files, memories, and work. For them, BeeStation Plus delivers a near turn-key solution that doesn’t demand IT knowledge or ongoing configuration, while still offering meaningful tools like Plex integration, two-way cloud sync, and internal snapshot recovery.

Synology Beestation Plus 8TB – Hardware Specifications

At the heart of the Synology BeeStation Plus is the Intel Celeron J4125, a quad-core x86 processor that, while not cutting-edge, is a substantial leap from the Realtek RTD1619B used in the original BeeStation. The J4125 brings integrated Intel UHD Graphics 600, enabling hardware video transcoding—critical for smooth 4K Plex streaming and responsive AI-powered photo recognition within BeePhotos. This CPU choice also allows Synology to run a broader range of services, including native Plex Media Server installation and enhanced indexing performance for large photo or document libraries. Paired with 4GB of DDR4 memory, the system is built to handle simultaneous user access and background tasks like backups and media processing without performance degradation—something the original model struggled with due to its lower RAM and ARM-based chip.

The BeeStation Plus ships with a pre-installed 8TB Synology HAT3310 hard drive, a 7200 RPM SATA HDD from Synology’s own verified drive lineup. While the device only supports a single internal bay, the included drive offers ample performance for most home and SOHO workloads, and the use of a higher-RPM disk ensures better responsiveness for large file transfers and indexing tasks. The storage is non-removable by design, as BeeStation products prioritize simplicity and stability over modularity. This also means there is no RAID support—underscoring that this device is not built for redundancy, but rather for centralized storage with optional external or cloud-based backup using BeeProtect or a secondary Synology NAS.

Connectivity is modest but practical. The system includes one 1GbE RJ-45 Ethernet port for network access and two USB 3.2 Gen 1 ports (one Type-A and one Type-C) for expanding storage or performing external backups. External drives can be browsed directly via BeeFiles or automatically backed up using the system’s USB Backup function. While some users may lament the lack of 2.5GbE or additional LAN ports, it’s worth noting that the target audience likely won’t saturate even gigabit speeds in everyday use. In real-world tests, BeeStation Plus can hit 150–180MB/s read speeds from its internal drive—enough to support simultaneous multimedia streaming and active file transfers across the network. The compact chassis also includes a cooling fan, a new addition over the passive original BeeStation, helping ensure thermal stability during extended workloads like Plex streaming or bulk photo indexing.

Synology Beestation Plus 8TB – BSM Software and Services

The BeeStation Plus is tightly integrated with Synology’s Bee-branded suite of applications, which form the foundation of its user experience. Chief among them is BeePhotos, a powerful photo management tool that automatically backs up images from mobile devices and organizes them using on-device AI for face, subject, and location recognition. Unlike cloud photo services, all indexing occurs locally, ensuring that sensitive images never leave the device. BeePhotos now supports iCloud Photo Backup, enabling direct migration of Apple photo libraries without requiring intermediate steps via your phone or computer. The web interface replicates the timeline-based design familiar to users of Google Photos or iCloud, complete with album views, smart filters, and Chromecast streaming. Meanwhile, BeeFiles acts as the central file manager, supporting version history, password-protected sharing, USB device browsing, and desktop sync via the BeeStation desktop client for Windows and macOS.

Beyond personal use, Synology has also included multi-user support for up to eight invited users, each with isolated private storage spaces and individual access rights. Users can connect to BeeStation from anywhere via the Synology cloud portal or mobile apps, allowing seamless collaboration and remote file access. BeeStation Plus also introduces native support for Plex Media Server, offering hardware-accelerated streaming of 4K content to TVs, tablets, or mobile devices. Integration is simplified through the BeeStation web portal, and libraries can be organized via BeeFiles’ dedicated “Plex Media Library” folder structure. Users can also take advantage of BeeProtect, a low-cost, unlimited-capacity cloud backup service that stores a full copy of the BeeStation’s data offsite—ideal for disaster recovery. Internal snapshot-based restore points add another layer of protection, allowing users to roll back the system in the event of accidental deletions or ransomware events, without relying on third-party services.

Synology Beestation Plus vs Synology DS224+/DS225+ and Beestation

The BeeStation Plus represents a clear technical upgrade over the original BeeStation, featuring a move from an ARM-based Realtek RTD1619B processor to a quad-core Intel Celeron J4125, along with a jump from 1GB to 4GB of DDR4 RAM. It also swaps the 5400 RPM 4TB HAT3300 drive for a faster 7200 RPM 8TB HAT3310, doubling the storage and improving responsiveness for tasks like AI photo indexing and multimedia playback. The inclusion of an active cooling fan further reinforces its suitability for continuous workloads, while added support for Plex Media Server and iCloud Photo Backup expands its capabilities far beyond the entry-level functionality of its predecessor. Both units share the same compact 1-bay form factor and cloud-integrated setup process, but the Plus model is built for heavier use, particularly in multi-user homes or for users archiving large libraries of photos and videos.

Synology Beestation Plus 8TB – Pricing and Release

The Synology BeeStation Plus (BST170-8T) launched globally in May 2025 with a suggested retail price of $369.95 USD (excluding VAT), positioning it as a compelling middle-ground between basic cloud drives and full NAS systems. This price includes the pre-installed 8TB Synology HAT3310 hard drive, three months of complimentary BeeProtect cloud backup, and full access to the BeeFiles and BeePhotos applications out of the box. While significantly more expensive than the original BeeStation’s $199.95 launch price, the BeeStation Plus delivers a considerable leap in performance, storage, and application support. Synology is clearly aiming to attract users looking to escape rising cloud subscription fees, with the device’s total cost of ownership undercutting comparable iCloud or Google One plans over just a few years. With increasing emphasis on private cloud solutions that are easy to deploy, the BeeStation Plus marks Synology’s most consumer-friendly push yet into the mainstream storage market.

Depuis plusieurs mois, le marché des NAS connaît un regain d’effervescence. Longtemps dominé par une poignée d’acteurs, ce segment attire désormais des entreprises issues de secteurs connexes, bien décidées à se faire une place. Qu’est-ce qui motive cet intérêt soudain ? Quels enjeux pour les acteurs établis comme Synology ou QNAP ? Décryptage…

Un nouvel appétit pour un marché de niche

Ce que l’on observe actuellement n’est pas l’émergence de start-up, mais plutôt l’arrivée de groupes déjà bien installés sur d’autres segments technologiques. Citons notamment UGREEN, réputé pour ses accessoires, ou encore des spécialistes du Mini-PC comme Minisforum, Beelink, ORICO ou Aoostar. Tous ont récemment investi le marché des NAS avec une stratégie affirmée : concurrencer les leaders traditionnels en s’appuyant sur leurs capacités industrielles existantes.

Un marché restreint, mais en croissance

Le NAS reste un produit de niche, à destination d’un public averti, professionnel ou technophile. Toutefois, il continue d’afficher une croissance régulière (souvent à 2 chiffres). Dans un contexte de diversification nécessaire pour les industriels chinois, ce segment représente un relais de croissance crédible, d’autant plus attractif qu’il ne requiert pas de rupture technologique majeure.

Un contexte favorable à l’entrée de nouveaux acteurs

Historiquement, la conception de NAS impliquait des investissements significatifs (matériel et logiciel). Aujourd’hui, la donne a changé. Des systèmes comme OpenMediaVault, TrueNAS, Unraid ou encore ZimaOS permettent aux utilisateurs de déployer eux-mêmes une infrastructure de stockage avancée, sans expertise pointue.

Par ailleurs, l’essor de Docker facilite la gestion et l’installation d’applications sur les NAS, réduisant encore la nécessité pour les fabricants de développer des interfaces logicielles propriétaires. Une économie de ressources considérable pour les nouveaux entrants.

Résultat : les barrières à l’entrée se sont considérablement abaissées, rendant ce marché bien plus accessible qu’il ne l’était il y a encore quelques années.

Des positions historiques sous pression

Les marques traditionnelles comme Synology, QNAP et Asustor ont longtemps prospéré grâce à la robustesse de leur matériel, à leur écosystème logiciel intégré et à un service après-vente éprouvé. Mais l’arrivée d’acteurs disposant de capacités industrielles comparables (voire supérieures) rebat les cartes.

Une bataille tarifaire en perspective

L’écart de prix entre les 2 marques est notable : les NAS  UGREEN sont proposés à des tarifs sensiblement inférieurs à ceux de Synology, pour un nombre de baies équivalent et des composants souvent plus récents. Un positionnement agressif qui n’implique pas nécessairement de compromis sur les performances, lesquelles se révèlent parfois supérieures.

Des consommateurs mieux informés

Autre évolution majeure : les utilisateurs, qu’ils soient professionnels ou particuliers, sont aujourd’hui plus avertis. Ils scrutent les composants, exigent une évolutivité tangible et comparent systématiquement les rapports qualité/prix. Les nouveaux venus pourraient tirer parti de cette exigence accrue, à condition de répondre aux standards attendus.

Vers une transformation du marché ?

Si le cycle de renouvellement des NAS reste relativement lent, les précédents ne manquent pas pour illustrer la rapidité avec laquelle un marché peut se transformer. L’exemple des robots aspirateurs est éclairant : iRobot (Roomba), autrefois leader incontesté, a été rapidement dépassé par des challengers asiatiques comme Roborock, Dreame ou Mova. Le NAS pourrait-il suivre une trajectoire similaire ?

La question reste ouverte. Mais elle mérite d’être posée, tant les conditions semblent réunies pour une recomposition accélérée du secteur.

En synthèse

Le marché du NAS est à l’aube d’une profonde recomposition. Sous l’effet combiné d’une pression concurrentielle accrue, de l’évolution des attentes utilisateurs et de la baisse des barrières technologiques, les lignes sont en train de bouger. Si les leaders historiques disposent encore de solides atouts, ils ne peuvent ignorer la montée en puissance de nouveaux acteurs agiles, bien décidés à redistribuer les cartes.

Synology a officiellement annoncé son nouveau NAS : DS1825+. Même s’il n’est pas encore disponible à la vente, ses spécifications techniques sont connues. Vous avez été nombreux à nous demander ce que ce nouveau modèle apporte face à son prédécesseur, le DS1821+. Voici donc une analyse comparative pour vous aider à faire un choix…

DS1825+ vs DS1821+

Les DS1825+ et DS1821+ occupent le segment particulier chez Synology. Tous les 2 proposent 8 baies en façade pour les disques durs ou SSD, ainsi que de 2 emplacements SSD NVMe accessible sous le châssis.

Ils prennent également en charge jusqu’à 2 unités d’extension de 5 baies, permettant d’atteindre un total de 18 disques. À noter : le DS1825+ est compatible avec la nouvelle unité d’extension DX525, connectée en USB-C, tandis que le DS1821+ repose sur des extensions en eSATA (DX517).

Processeur et RAM

Le Synology DS1825+ embarque un processeur AMD Ryzen V1500B (quad-core à 2,2 GHz). C’est exactement le même que son prédécesseur, le DS1821+. La bonne nouvelle, c’est que la RAM a été doublée ici, le DS1825+ possède 8 Go DDR4 ECC de base (extensible jusqu’à 32).

Connectique

Le DS1825+ gagne 2 ports USB Type-C et 2 ports réseau 2,5 Gb/s. C’est vraiment la grande nouveauté de la gamme DSx25+.
Comme avec le DS1821+, le DS1825+ conserve l’emplacement son emplacement PCIe permettant de recevoir une carte réseau (1* 10 Gb/s, 2* 10 Gb/s ou encore 2* 25 Gb/s).

Le DS1825+ se distingue principalement par sa connectique modernisée :

• 2 ports USB-C font leur apparition (contre aucun sur le DS1821+)
• 2 ports réseau 2,5 Gb/s remplacent les 4 ports 1 Gb/s de l’ancien modèle

Attention, les ports USB-C ne sont utilisables qu’avec des unités d’expansion Synology. En effet, clé et SSD externe ne fonctionnent pas sur ces ports. L’emplacement PCIe est toujours présent, permettant d’ajouter une carte réseau 10 Gb/s ou même 25 Gb/s.

Toutefois, on note la suppression de 2 ports USB 3.0 et des ports eSATA, ce qui pourrait poser problème à certains professionnels ou utilisateurs avancés.

Politique de compatibilité plus stricte

Synology poursuit sa stratégie controversée : comme pour les autres modèles de la série DSx25+, l’utilisation de disques certifiés est désormais obligatoire. À ce jour, seuls les disques Synology sont officiellement compatibles. Une contrainte qui risque d’en rebuter plus d’un.

Tableau comparatif DS1825+ vs DS1821+

	DS1825+	DS1821+

Score CPU Benchmark	4829 points	4829 points
Disponibilité	À venir	Immédiate
Prix au lancement	À confirmer	1035€

Faut-il passer au DS1825+ ?

Le DS1825+ remplace formellement le DS1821+, mais en y regardant de plus près, les améliorations sont très limitées. On perd des ports (USB 3.0, eSATA), on gagne du USB-C et un réseau légèrement plus rapide en 2,5 Gb/s… mais cela ne conviendra pas à tous les usages, notamment en environnement professionnel où le 10 GbE natif devient souvent indispensable.

La mémoire de base est doublée, mais 8 Go restent insuffisants pour de nombreux cas d’usage avancés (virtualisation, conteneurs, etc.).
Enfin, la restriction sur les disques non certifiés pourrait être un vrai frein pour les utilisateurs soucieux de leur liberté de choix ou de leur budget.

En synthèse

Le DS1825+ n’apporte pas de véritable révolution. Il constitue une évolution mineure. Si vous possédez déjà un DS1821+, il n’y a aucune urgence à migrer. En revanche, si vous partez de zéro, le choix dépendra surtout de votre besoin en connectique, de votre tolérance à la politique de disques imposée… et bien sûr du prix final, encore inconnu.

Synology (FINALLY) has an NVMe Flash Server – The Synology PAS7700 System

Synology are seemingly going ‘all guns blazing’ at Computex 2025 this year, with a wide array of hardware and software solutions being revealed at the event. Many of these we already know about via official and unofficial reveals over the last 6 months or so, how the PAS NVMe flash storage system is one that was actually originally shown last year at the brand’s 2024 Solution Exhibition in Taipei, this was still an early prototype system and was built using an existing 2U chassis and was much more comparable to existing SAS storage systems from the brand. However, the PAS NVMe Flash system has seemingly (and RAPIDLY) evolved since it was first revealed as an early 12 bay prototype 2U rackmount last year into a dual active 4U Behemoth solution that is significantly more focused on leveraging the performance benefits of NVMe, alongside the scale-out, redundancy and failover of other enterprise tier Synology NAS solutions.

Synology already has an existing range of SSD Flash soltuons, in their Flashstation series, but this proposed PAS7700 system is a completely different class of system against those more classic DSM hardware systems. Synology has been somewhat behind the curve when it comes to NVMe flash systems in the last few years (both entry class m.2 NVMe systems at desktop, but also larger business and enterprise class NVMe over U.2/U.3 compared with competitors such as QNAP (and their FX/FU series), but the PAS is hoping to fill this gap in the brand’s portfolio at this higher tier of buyer. So, what do we know so far?

Synology PAS7700 Hardware Specifications

The Synology PAS7700 is a 4U rackmount dual-node NVMe flash storage system engineered for high-performance, mission-critical enterprise workloads. Designed with a non-disruptive architecture, it enables active-active operations across both nodes, ensuring continuous data availability and efficient load distribution without single points of failure. Each node occupies 2U of rack space and operates independently, yet cooperatively, allowing both to concurrently handle client requests and internal processes. This design eliminates the need for manual failover while maintaining performance even during node maintenance or partial outages.

At the heart of each node lies a 24-core AMD EPYC processor, optimized for dense, multi-threaded workloads such as data analytics, database transactions, and large-scale virtualization. These processors provide ample PCIe Gen4 lanes to support high-speed interconnects, storage interfaces, and compute operations. Each node is equipped with 64GB of DDR4 ECC memory out of the box, with upgrade support up to 1TB. This high memory ceiling is particularly beneficial for large-scale caching, deduplication, and inline compression tasks in high IOPS environments. Memory cache protection mechanisms are built in to preserve data integrity during unexpected power loss, using supercapacitors or battery-backed modules.

The storage backplane supports a total of 48 U.2 or U.3 NVMe SSDs across the chassis—24 per node—maximizing both performance and density. Drive control is split between the native AMD EPYC-integrated PCIe controllers and additional PCIe switching and management provided by ASMedia Technologies, likely to balance performance across multiple backplanes and mitigate PCIe bottlenecks. This configuration ensures that each SSD can be utilized to its full potential with minimal latency and optimal throughput. Network connectivity includes a dedicated 1GbE copper port per node for management, along with dual 10GbE NICs for data operations. These ports support link aggregation and failover, with options for expansion to higher-speed interfaces expected, though not yet confirmed. The PAS7700 likely supports several PCIe expansion slots internally, allowing future upgrade paths to 25/40/100GbE if required. This flexibility positions the unit for use in diverse network topologies and high-bandwidth enterprise infrastructures.

That said, we should discuss the thorny subject of storage media. Synology has recently implemented a more stringent hardware compatibility policy, mandating the use of Synology-branded or certified storage media in its latest 2025 Plus Series NAS devices. This policy restricts full functionality and support to only those drives that have been validated by Synology, potentially limiting user flexibility and increasing costs due to reduced third-party options. Currently, Synology’s in-house SSD lineup includes SATA SSDs and M.2 NVMe SSDs, with capacities up to 800GB. This raises questions about their plans for higher-performance storage media suitable for systems like the PAS7700, which is designed for demanding enterprise workloads. As of now, Synology has not announced any U.2 or U.3 NVMe SSDs in their product range. Given the PAS7700’s reliance on high-speed NVMe storage, it’s unclear whether Synology will expand its SSD offerings to include higher-capacity and performance options or if they will certify third-party drives for use with this system. The company’s updated compatibility lists will be crucial for users to identify approved drives. Until more information is available, potential PAS7700 users may need to consider the implications of Synology’s hardware compatibility policies on their storage choices.

Synology PAS7700 Services and Flash Protocols

The Synology PAS7700 supports a diverse array of storage access protocols optimized for NVMe over Fabrics (NVMe-oF), ensuring compatibility with modern data center architectures and latency-sensitive applications. These protocols are tailored to support high-throughput and low-latency workloads across both local and remote environments, catering to sectors such as virtualized infrastructure, high-performance computing, and real-time analytics.

Among the supported technologies are NFS RDMA, NVMe-TCP, NVMe over Fibre Channel (NVMe-FC), and NVMe over RoCE (Remote Direct Memory Access over Converged Ethernet). These protocols differ in terms of performance characteristics, implementation complexity, and deployment environments, giving administrators flexibility in aligning the system’s networking stack with existing infrastructure and performance objectives. These include:

• NFS RDMA (Remote Direct Memory Access):

  • Enhances traditional NFS performance by bypassing the CPU for memory transfers.

  • Significantly reduces latency and CPU usage in environments using NFSv4.x.

  • Ideal for high-performance, low-latency use cases like virtual machines or scientific computing.

• NVMe-TCP (NVMe over TCP/IP):

  • Extends NVMe-oF across standard Ethernet networks without requiring specialized hardware.

  • Enables NVMe-level performance benefits using existing TCP infrastructure.

  • Easier to deploy in enterprise environments with mixed networking equipment.

• NVMe-FC (NVMe over Fibre Channel):

  • Combines the speed of NVMe with the reliability of Fibre Channel.

  • Suitable for enterprises already using Fibre Channel SANs.

  • Offers low-latency performance with high stability and established zoning capabilities.

• NVMe/RoCE (RDMA over Converged Ethernet):

  • Provides near-direct memory access over Ethernet without involving the CPU.

  • Achieves ultra-low latency for applications such as real-time trading or video rendering.

  • Requires a compatible network fabric with lossless Ethernet configuration.

We are still awaiting confirmation on whether this will be running on traditional DSM, a dual controller variation (such as found on the current UC3200 0 Active/Active system), a multinode management variation (as found in the GS/GridStation system, or a brand new splinter of DSM services (as found in the DP series with Active Protect).

Synology PAS7700 Failover and Redundancy

The Synology PAS7700 is designed with full-stack redundancy to eliminate single points of failure and minimize service disruption across hardware, software, and protocol layers. Its dual-node active-active design enables uninterrupted operations even during firmware updates, system maintenance, or unplanned hardware failures. This architecture ensures that both nodes can operate independently while maintaining synchronized data access and state, effectively enabling non-disruptive service continuity in multi-user enterprise environments. Each layer of the system—from networking to storage to memory—is fortified with specific failover mechanisms. Networking is protected via IP failover configurations, allowing services to automatically reroute through a secondary interface or node should a primary link fail. The system also supports Multipath I/O (MPIO) across iSCSI, Fibre Channel, and NVMe-oF protocols, ensuring high availability and load balancing across multiple paths. On the protocol level, persistent handle support in SMB and grace periods in NFS ensure that client sessions remain intact during failovers or server transitions.

Synology further implements failover at the component and data protection level. Memory modules are equipped with cache protection to safeguard in-flight data in the event of power loss, typically via battery backup or capacitor-based retention systems. On the storage layer, support for RAID-TP (triple parity) adds an extra layer of disk fault tolerance, protecting against up to three simultaneous drive failures. Additionally, enterprise-grade SSDs used in the PAS7700 are expected to include power loss protection (PLP), preserving cached writes during sudden shutdowns.

• Protocols:

  • SMB Persistent Handles: Maintains client file handles during failover events.

  • NFS Grace Periods: Allows NFS clients to re-establish sessions without data loss.

  • MPIO: Multipath I/O for load balancing and failover across multiple transport paths.

• Networking:

  • IP Failover: Automatically reroutes network services to a standby node or NIC if a primary fails.

• System-Level:

  • Hardware Failover: One node takes over if the other becomes non-functional.

  • Upgrade Failover: Supports live system or firmware updates without downtime.

• Memory:

  • Cache Protection: Retains volatile memory contents in the event of power loss using supercaps or batteries.

• Storage:

  • RAID-TP: Triple parity RAID support for enhanced data redundancy.

  • Power Loss Protection (PLP): SSDs preserve unwritten data during power failure.

Whether other specific SSD/Flash services that are currently available on devices like the Flashstation series (such as RAID F1 for controlled and predicted NAND wearing) will also be integrated here on scale are yet to be confirmed. While the full software environment and feature set of the Synology PAS7700 are yet to be confirmed, its hardware architecture and protocol support position it as a serious entry into the enterprise flash storage segment. With dual-node active-active operation, extensive NVMe protocol compatibility, and comprehensive failover mechanisms, the PAS7700 is clearly designed for organizations that require uncompromising uptime and performance. As more details emerge at Computex 2025, the PAS7700 is expected to clarify its role within Synology’s broader storage portfolio—particularly how it compares to the UC series and where it fits in demanding environments such as virtualized infrastructure, high-frequency transactional workloads, and critical business continuity deployments.

Bonjour à tous,

J’espère que vous allez bien et que vous avez profité des ponts pour vous ressourcer. Ce n’est pas fini, il y en a un autre dans 2 semaines Pour ma part, je n’en ai pas forcément profité… mais j’avoue que d’avoir une coupure dans la semaine, ça fait du bien.

Comme vous avez pu le constater, il y a eu beaucoup d’articles ces dernières semaines. Il faut dire que l’actualité autour des NAS a été riche et elle va continuer quelques semaines. En effet, avec le Computex qui arrive à grands pas (du 20 au 23 mai), les annonces devraient fleurir. Plusieurs tests très attendus ont été publiés et d’autres sont à venir. J’ai pris un peu de retard dans mes mails et je vous prie de m’excuser. Je reçois de plus en plus de demandes : tests, tutos et autres. Malheureusement, je suis quasiment seul aux commandes et moi aussi… j’ai besoin de lâcher le clavier de temps en temps.

Du côté des films et séries TV, j’avoue que j’ai regardé Conclave (oui c’est en lien avec l’actualité récente). Cela reste une fiction, mais j’ai aimé. Comme beaucoup parlent de Balle Perdue 3, je me suis dit que j’allais au moins regarder le premier opus (Balle Perdue). Ça se regarde, mais franchement… c’est pas fou. Enfin, j’ai regardé The Pitt. C’est une série TV ou l’on retrouve Noah Wyle (producteur également), encore dans un service des urgences. Elle se laisse regarder, même s’il faut avouer que c’est très loin du côté glamour de la série des années 90. Là, c’est assez gore… j’avoue que j’ai détourné les yeux à deux ou trois reprises. C’est intense, on aime ou on déteste.

Allez, je vous souhaite une excellente journée…

The Synology DS925+ versus Synology DS923+ – Buy OLD or BUY New?

Every few years, when Synology chooses to refresh several of its popular devices—updating a number of its hardware features—new buyers and those looking to upgrade have a choice to make. Is it nobler in the mind to purchase the more affordable and already well-known older-generation device, or hold out and purchase the brand-new, refreshed, updated model with its improved hardware but likely slightly increased price tag? Refreshes are planned for 2025. Today, I want to discuss whether users should consider purchasing the DS923+—which has been in the market for several years now—or set their sights on the newer DS925+ NAS. On the face of it, many will consider this an easy choice, as newer hardware likely means a better system. However, the reality is much more nuanced. Alongside older-generation hardware having had a greater deal of time to be developed within its own ecosystem and by third-party developers, there is also the question of whether newer-generation hardware really is genuinely a hardware upgrade. Or do you have the potential to miss out on certain hardware features in the new generation that may have become legacy options (remember the DS920+?). Which one deserves your money and your data?

When we examine the CPU specifications in isolation, it’s clear that the V1500B in the DS925+ delivers greater multi-core throughput, while the R1600 in the DS923+ offers higher single-core clock speeds. But understanding how these numbers affect real-world tasks within Synology’s DiskStation Manager (DSM) is far more meaningful. Thanks to its 4-core, 8-thread configuration, the DS925+ excels in multi-threaded workloads, which is evident in its higher software limits. It supports up to 8 virtual machines and 8 virtual DSM instances through Virtual Machine Manager, making it ideal for users running containerized services, development environments, or isolated OS instances. Additionally, it handles more concurrent SMB connections (up to 40 with RAM expansion), supports up to 150 Synology Chat users, 80 Synology Drive users, and 80 Synology Office users—all reflecting its capacity to manage a larger user base and more simultaneous services without bottlenecks.

For surveillance and media workloads, the DS925+ also pulls ahead, matching the DS923+ in the number of supported camera channels (up to 40 cameras and 1200 FPS at 1080p H.265), but benefiting from more headroom when additional tasks are running in parallel—such as snapshots, backups, or AI-powered photo indexing via Synology Photos. Meanwhile, the DS923+, with its faster per-core performance and support for PCIe expansion, remains well-suited to users running lighter, more focused workloads or who plan to scale via hardware add-ons, such as a 10GbE network card. It still supports a respectable 4 VMs, 60 MailPlus users, and 50 users each for Synology Drive and Office, making it perfectly adequate for small teams or power users who prioritize customization and future expansion. While both CPUs are capable, the DS925+ delivers superior multi-user, multi-tasking performance, aligning closely with higher software thresholds and offering better out-of-the-box readiness for more demanding and concurrent applications across Synology’s DSM suite.

• R1600 (DS923+) excels in single-core performance (better for fast app responsiveness and lighter workloads).

• V1500B (DS925+) dominates in multi-core performance (better for multitasking, virtualization, and heavier parallel tasks).

• The V1500B also has more PCIe lanes (16 vs 8), which may benefit systems with more storage or networking needs.

Synology DS925+ vs DS923+ – Software Specifications

Beyond hardware, the real power of a NAS lies in what it enables users to do—and that’s where software specifications take center stage. Synology’s DSM (DiskStation Manager) operating system unlocks a vast suite of applications and services, from virtualization and backup to media streaming, file sharing, and surveillance. However, the scope and scale of these capabilities are directly influenced by the underlying system hardware and memory architecture. Let’s compare the software capabilities of the Synology DS925+ and DS923+, not just in terms of what each system can technically support, but how far each can be pushed in real-world use. We examine backup limits, virtual machine support, hybrid cloud services, user and group management, surveillance channel support, and more—offering a complete picture of each system’s software potential under DSM 7.2.

While both the Synology DS925+ and DS923+ run the same robust DSM software and offer access to the full Synology ecosystem, their software ceilings differ significantly—reflecting the difference in overall system capability. The DS925+ consistently supports higher concurrent workloads across nearly every category. It enables up to 8 virtual machines, compared to just 4 on the DS923+, and supports double the Virtual DSM instances. It also allows for more Synology Chat users (150 vs 100), more Synology Office and Drive users (80 vs 50), and handles twice the VPN connections (8 vs 4). For collaborative environments, this means smoother performance when multiple users are accessing files, editing documents, or messaging in real time. It’s also more equipped for enterprise use with double the number of Shared Folder Sync tasks and higher MailPlus user capacity (90 vs 60 users), making it ideal for larger teams or more demanding deployment scenarios.

Meanwhile, the DS923+ still provides an impressive software suite, especially considering its smaller hardware footprint. It supports all major DSM features—Snapshot Replication, Hyper Backup, High Availability, Surveillance Station, and more—making it a solid choice for small businesses or power users who may not need the extended capacity but still want rich functionality. Its support for 10GbE upgrades via PCIe also allows for flexible scaling, even if its base configuration starts at a lower software threshold. The DS925+ is better suited for multi-user environments, heavier workloads, and broader deployment, while the DS923+ is ideal for lighter workflows, cost-sensitive setups, or users planning to grow into the system gradually. Understanding these software limitations and allowances is key to choosing the right NAS for your workload, user count, and future planning.

• The DS925+ outperforms the DS923+ in:

  • Max volume size (up to 200 TB with RAM upgrade)

  • SMB connections

  • Shared folder sync tasks

  • Synology Chat users

  • MailPlus users

  • Synology Drive & Office users

  • Virtual machines and VPN connections

• The DS923+ has an edge only in volume count, supporting 64 internal volumes vs 32.

Synology DS925+ vs DS923+ NAS – Hard Drive and SSD Compatibility

As of this writing, Synology is taking a more restrictive stance on third-party drive support, especially with the introduction of its 2025 hardware series—including the DS925+. Since launching its own branded SSDs and HDDs in 2020–2021, Synology has steadily reduced the number of third-party drives listed as compatible with DSM. This trend escalated with DSM 7.1 in 2022, which introduced warning states for systems using unverified drives.

Although the impact of these warnings was later reduced, Synology has continued moving toward a locked-down storage ecosystem. The DS925+ marks a significant escalation. At launch, it only lists Synology-branded drives as compatible, and more critically, the system will not allow DSM initialization at all if unsupported drives are detected. This is a sharp departure from earlier practices where unverified drives merely triggered warnings post-setup. Despite sharing identical internal hardware with earlier NAS models from 2020 and 2023—which still support a wide range of drives from Seagate, WD, Toshiba, Samsung, and others—the DS925+ now enforces this compatibility policy at the firmware level.

In contrast, the DS923+ remains more flexible. While it will flag third-party drives as “unverified,” it still allows users to fully initialize the system, create storage pools, and access all DSM storage services without restriction. This flexibility makes the DS923+ a more appealing option for users who already own or prefer third-party HDDs and SSDs, particularly in regions where Synology’s own media is either overpriced or hard to source. Compounding the issue is the lack of clarity around Synology’s rollout. The policy was first disclosed on Synology’s German site and remains vaguely worded on the official DS925+ product page. There’s still no definitive answer on whether compatibility will expand to include major third-party brands—raising concern for system integrators, resellers, and first-time buyers.

If Synology’s goal is to ensure higher reliability through tighter integration, it should match that with transparent testing data, global pricing consistency, and readily available stock. In many regions, Synology drives are neither as accessible nor as competitively priced as third-party equivalents, which makes this policy feel restrictive rather than protective. While existing users can still migrate third-party drives from an older NAS into a DS925+, this is of little comfort to new buyers building from scratch. And the inconsistency with the DS923+—which continues to operate under the older, more open approach—only adds to user confusion. Synology appears to be transitioning toward a closed appliance model, where software, hardware, and media are tightly controlled. Whether this delivers long-term benefits or alienates a portion of its user base remains to be seen. For now, the DS925+ presents both a warning and a decision point for those evaluating their next NAS—especially if they rely on third-party drives.

Synology DS925+ vs DS923+ NAS – Which Should You Buy?

The DS923+ is a NAS system that, when first launched by Synology at the end of 2022, was met with mixed reactions. This was largely due to Synology shifting the system’s focus away from multimedia and GPU-accelerated tasks, and instead toward file processing and business-oriented deployments. Fast forward a few years, and the rest of Synology’s portfolio has realigned—bringing back more home and multimedia models—making this more utilitarian, file-centric 4-bay system easier for users to appreciate in context. That said, the DS925+ is the better choice in almost every way. It features a processor originally designed for higher-tier business-class systems, offering more cores, more threads, and greater performance potential across productivity tasks and multi-user workloads. Synology has also finally introduced 2.5GbE on this system—an overdue improvement that significantly enhances out-of-the-box network speeds compared to the 1GbE-only DS923+. As long as the DS925+ is priced within a reasonable 5% margin of the DS923+’s original launch price, it stands as the more capable system by default. However, it does come with a notable caveat: the lack of a 10GbE upgrade option. Unlike the DS923+, which includes a PCIe Gen3 x2 slot allowing for a future 10GbE NIC upgrade, the DS925+ is capped at its built-in 2.5GbE ports. While this still provides a theoretical 6Gbps of total bandwidth across both ports via link aggregation, it means there’s no room for expansion beyond that ceiling. This limitation becomes particularly relevant for users planning to fully populate the NAS with high-performance SATA SSDs or utilize M.2 SSD storage pools. In these cases, the network will eventually become a bottleneck—one that the DS923+ can avoid through its 10GbE upgrade path. Additionally, the DS923+ supports a wider range of third-party HDDs and SSDs, allowing greater flexibility and cost control, especially in regions where Synology-branded drives are less available or more expensive. The DS923+ will still let you initialize, create storage pools, and run DSM services using unverified third-party drives, unlike the DS925+, which now enforces stricter media validation at the OS level.

Reasons to Buy the Synology DS923+

Reasons to Buy the Synology DS925+

Faster 2.5GbE Networking Out-of-the-Box – Dual 2.5GbE ports offer higher baseline network speeds (up to 6Gbps aggregated), doubling the network performance compared to the DS923+ without requiring expansion cards. More Powerful Processor (More Cores/Threads) – The V1500B CPU offers 4 cores and 8 threads, delivering superior multitasking and heavier workload handling, especially for virtual machines, multiple users, and simultaneous services. Quieter Operation – The DS925+ operates at a lower idle noise level (20.5 dB vs 22.9 dB), making it better suited for office, home office, or studio environments where sound matters. Higher User and Service Limits – Thanks to the more powerful CPU, the DS925+ supports more Synology Drive users, Synology Office users, Synology Chat users, more concurrent SMB connections, and more virtual machines than the DS923+. Better Out-of-the-Box Experience – With stronger networking, higher multi-threaded performance, and no need for immediate upgrades, the DS925+ is ready to deliver higher performance without any additional investment, perfect for users who want maximum capability from day one.

PCIe Expansion for 10GbE Upgrades – The DS923+ features a PCIe Gen3 x2 slot, allowing users to install a 10GbE network card later, massively boosting network speeds beyond the built-in 1GbE ports. Broader 3rd-Party Drive Compatibility – Unlike the DS925+, the DS923+ allows full system initialization, storage pool creation, and DSM services even with non-Synology hard drives and SSDs—giving users more flexibility and choice. Lower Power Consumption and Heat Output – The DS923+ is slightly more energy-efficient in both active use and hibernation modes, making it a better fit for always-on environments where power savings add up over time. Potentially Lower Price (Especially Post-DS925+ Launch) – As the newer DS925+ replaces it, the DS923+ is likely to see discounts and wider availability, offering excellent value for budget-conscious users without sacrificing capability. Ideal for Customization and Long-Term Scalability – With the ability to upgrade the network, use a wider range of drives, and maintain full DSM functionality, the DS923+ is better suited for users who plan to evolve their setup over time.

In practical terms, the DS925+ is the stronger out-of-the-box choice, especially for users who value simplicity, improved default performance, and do not anticipate needing higher-than-2.5GbE networking down the line. However, the long-term value proposition becomes murkier when you factor in the DS923+’s PCIe expansion, broader drive compatibility, and the potential price drops that will follow its ageing status in Synology’s lineup. In short, the DS925+ is the better NAS on day one—more powerful, faster, and quieter. But if you’re planning for day 1,000, it’s worth pausing to consider whether the expandability and media flexibility of the DS923+ may be a better fit for your storage and networking needs over the next five to seven years.

Synology a officiellement annoncé son nouveau NAS : DS1525+. Même s’il n’est pas encore disponible à la vente, ses spécifications techniques sont désormais connues. Vous nous avez demandé ce qu’apporte ce modèle face à son prédécesseur, le DS1522+. Voici donc un comparatif pour vous aider à faire un choix éclairé….

DS1525+ vs DS1522+

Les DS1525+ et DS1522+ se positionnent dans le haut de gamme grand public chez Synology. Ils disposent de 5 emplacements en façade pour disques durs ou SSD, ainsi que de 2 emplacements SSD NVMe situés sous le châssis (pour du cache ou comme volumes de stockage).

Ils peuvent également accueillir 2 unités d’expansion de 5 baies, permettant d’atteindre un total de 15 disques. À noter que le DS1525+ introduit une nouveauté : la prise en charge du DX525, une nouvelle unité d’extension connectée en USB-C.

Processeur

Synology poursuit l’intégration de processeurs AMD Ryzen dans ses NAS. Le DS1525+ embarque un Ryzen V1500B (quad-core à 2,2 GHz), en remplacement du Ryzen R1600 (dual-core à 2,6 GHz de base, 3,1 GHz en boost) du DS1522+. Ce changement est similaire à ce qu’on a observé sur les modèles DS925+ et DS923+.

Le nouveau processeur (sortie 2018) apporte un gain de performances, en particulier en multitâche. En revanche, aucun des 2 modèles ne dispose d’iGPU, ce qui limitera les capacités de transcodage vidéo matériel.

Mémoire ECC

Les 2 NAS intègrent 8 Go de mémoire DDR4 ECC, extensible jusqu’à 32 Go. C’est un bon point, surtout comparé au DS925+ livré avec seulement 4 Go. La mémoire ECC permet de corriger automatiquement certaines erreurs et d’améliorer la stabilité, même si son intérêt reste limité sur un NAS ne reposant pas sur ZFS.

Connectique

Le DS1525+ gagne 2 port USB Type-C et 2 ports réseau 2,5 Gb/s. C’est la grande nouveauté de la gamme DSx25+, trop longtemps attendu.
Aussi, contrairement au DS925+, le DS1525+ conserve l’emplacement pour la carte réseau 10 Gb/s (en option). Cette dernière permet d’atteindre jusqu’à 1181 Mo/s en lecture et 1180 Mo/s en écriture séquentielle, selon Synology.

Politique de compatibilité plus stricte

Le point noir reste la restriction sur les disques certifiés. Synology impose l’utilisation de modèles validés suivant un cahier des charges très stricte. A l’heure actuelle, aucun disque n’est encore officiellement compatible avec la série DSx25+… sauf les disques Synology. Une contrainte qui risque de rebuter certains utilisateurs souhaitant réutiliser leurs propres disques.

Disponibilité	À venir	Immédiate
Prix au lancement	815€ (à confirmer)	775€

En synthèse

Le DS1525+ est une légère évolution du DS1522+. Certes, il y a quelques améliorations, comme le processeur et les ports réseau 2,5 Gb/s… mais le Multi-Gig était déjà possible grâce à l’ajout d’une carte 10 Gb/s.  Avec sa nouvelle politique de disques certifiés, pas sur ce que ce nouveau NAS trouve sa place.

Certains utilisateurs lui préféreront le DS1522+ avec son prix affiché actuellement à environ 757 €.

Synology vient d’annoncer l’arrivée prochaine de 2 nouveaux NAS : DS1525+ et DS1825+. Ces modèles font partie de la nouvelle génération DSx25+. Au programme : un processeur AMD Ryzen V1500B, 8 Go de RAM DDR4 ECC, 2 ports réseau 2,5 Gb/s et…

Synology DS1525+ et DS1825+

Les nouveaux NAS DS1525+ et DS1825+ partagent beaucoup de points communs. Tout d’abord, ils possèdent respectivement 5 et 8 baies en façade et 2 emplacements NVMe pour des SSD (accessibles par le dessous). Ils pourront chacun recevoir jusqu’à 2 unités d’expansion (DX525) pour ajouter 2*5 baies supplémentaires.

Ils sont construits autour du processeur Quad Core AMD Ryzen V1500B cadencé à 2,2 GHz, épaulé par 8 Go de RAM en DDR4 ECC (extensible jusqu’à 32 Go). Oui, c’est le même que le DS925+ ou les anciens DS1621+ et DS1821+.

Connectivité et évolutivité

Le DS1525+ vient remplacer le DS1522+, alors que le DS1825+ remplace le DS1821+…

DS1525+

 

Au niveau de la connectique, le DS1525+ propose : 2 ports USB 3.0 (dont un à l’avant), 2 ports USB Type-C (pour les unités d’expansion), 2 ports réseau 2,5 GbE… et 1 emplacement PCIe Gen 3 permettant de recevoir la mini-carte 10 Gb/s (E10G22-T1-Mini).

Souvenez-vous, nous avions apprécié son arrivée avec le DS923+… avant de voir l’emplacement disparaitre avec le DS925+.

DS1825+

Du côté du DS1825+, ce dernier dispose : 3 ports USB 3.0 (dont un à l’avant), 2 ports USB Type-C (pour les unités d’expansion), 2 ports réseau 2,5 GbE… et 1 emplacement PCIe Gen 3 x8 permettant de recevoir une carte réseau (1* 10 Gb/s, 2* 10 Gb/s ou encore 2* 25 Gb/s). À noter que ce modèle dispose également d’une alimentation interne, contrairement aux DS1525+ et DS925+.

Politique restrictive

Avec la série DSx25+, Synology applique une politique de compatibilité stricte. Si vous installez des SSD ou disques durs non listés, le système affiche des alertes, peut désactiver le cache NVMe ou refuser la création d’un volume. Synology limite ainsi l’usage de marques tierces comme Seagate IronWolf ou WD Red. Seul les produits Synology pour l’heure compatible avec les NAS Synology. Cette démarche, présentée comme un gage de fiabilité, se traduit par un surcoût et réduit la liberté de mise à niveau pour tous.

Synology va devoir jouer la carte de la transparence et fournir rapidement une liste de disques certifiés… autre que ses propres disques.

Prix et disponibilité

Au moment où nous écrivons ces lignes, Synology n’a pas encore fourni de date officielle de sortie. Ce devrait arriver très rapidement, avant le Computex. Aucun prix n’a pour le moment fuité. Nous ne manquerons pas de modifier cet article le moment venu.

Pour en savoir plus sur ces nouveaux produits, rendez-vous sur les pages du DS1525+ et DS1825+…

UGREEN Headquarters in Shenzhen, China – NAS Plans, Company Culture, R&D and More

As part of a week-long visit to Shenzhen to better understand the operations behind some of the rising tech brands in China, I arranged a tour of UGREEN’s headquarters. The visit was not sponsored or paid for by UGREEN, nor was I invited by them directly. It was simply part of a wider initiative to learn more about the companies producing network storage hardware that is increasingly popular in Western markets. Although UGREEN previously sponsored a separate video about their NAS hardware, this trip was independently funded and organized. I spent roughly four to five hours across several buildings at their primary site in Longzhen Industrial Park, Guangdong Province, gaining insight into their development process, support infrastructure, and product plans.

So, what do we know about UGREEN Online already? ​Founded in 2012 by Zhang Qingsen in Shenzhen, China, UGREEN began as an Original Equipment Manufacturer (OEM) producing data cables for international brands. Recognizing the potential for greater innovation and brand identity, Zhang transitioned the company from OEM services to establishing UGREEN as an independent brand. The company specializes in a wide range of consumer electronics, including USB hardware, charging devices, audio equipment, and mobile accessories. Over the years, UGREEN has expanded its presence to over 100 countries, earning a reputation for delivering high-quality, affordable products. The company’s commitment to research and development, design, manufacturing, and brand marketing has solidified its position as a global leader in the consumer electronics market

UGREEN’s operation is spread across four main buildings, each with a distinct purpose: international and domestic marketing, customer support, and research and development. Most of my time was spent in the R&D building and parts of the customer service center.

The first area I visited was their product showroom, a space clearly designed for internal partners and B2B visitors rather than public foot traffic. The showroom featured one of every UGREEN product, including several items not yet announced publicly, with placeholders on the shelves suggesting upcoming Thunderbolt 5 and new NAS models.

Staffing levels across the buildings seemed consistent with what you’d expect from a company scaling into premium storage solutions. I counted around 40 to 50 people in support and R&D departments alone, with visible crossover between teams. The support center operated in what appeared to be a traditional open-office structure, with teams seated in long desk arrays. While I couldn’t film this area due to consent concerns (and was provided with some official footage), the impression was of a well-staffed, professional operation. Observing lunch break foot traffic—easily 60 or 70 people exiting en masse—it became clear that UGREEN’s core NAS and support teams were substantial and not limited to a token few.

One of my central questions going into the visit was about UGREEN’s approach to support. Network-attached storage is a 24/7 solution for most users and competes with both premium and open-source platforms. I was particularly interested in how UGREEN intended to position themselves with regard to long-term reliability and assistance. Their answer was partly logistical—dedicated support staffing—and partly software-focused. In discussions with their development team, it was apparent that software enhancements are now a priority following their initial hardware deployment. One example discussed was the demand for iSCSI support, which has been slower to arrive due to regional differences in usage habits.

UGREEN’s proprietary NAS OS, UOS, is based on development efforts that began with Chinese-market NAS solutions around 2020. With the newer DXP series expanding into international markets, UOS has been undergoing rapid westernization. There was a candid discussion about cultural and user-base differences that caught the team off-guard—particularly in the importance of specific protocol support and integrations. While I signed an NDA preventing me from disclosing every part of the roadmap, the general message was that the next two years will focus primarily on maturing the UOS software stack, including AI-driven features, broader language support, and improved cross-platform expansion options.

A significant portion of the discussion centered around hardware expansion. UGREEN has developed a range of DAS (direct-attached storage) solutions, many of which are still only available in China, but which they intend to integrate more fully with their NAS lineup globally and serve as NAS expansion devices. USB4 and Thunderbolt connectivity is also in active development, with Windows support reportedly complete but ongoing issues with macOS integration delaying a broader release.

These updates were presented not as future aspirations but as active, iterative engineering challenges currently underway, which aligns with the company’s overall stated intention of refining rather than rushing.

Arguably the most distinctive part of the visit was the NAS Lab—a dedicated test space designed to simulate real-world deployment scenarios. Unlike many brands that showcase NAS capabilities in tightly controlled demo booths or static displays at trade shows, UGREEN has constructed multiple functioning environments: a home media suite, an office collaboration space, and a creative studio tailored to video editing.

These setups are used internally to identify pain points in both hardware and software by replicating user workflows in a live, interactive context. It was clear from the walkthrough that this lab is an active part of their development cycle and not just a showroom for visitors.

These test suites enabled the company to simulate multi-user environments, such as households streaming content while backups run in parallel or video editors accessing high-bitrate files remotely. The lab also helps visualize inefficiencies and inconsistencies in system deployment, such as UI design issues or performance bottlenecks in hybrid-use cases.

Such testing environments are more commonly found in laptop and mobile device labs but are rare in the NAS world, especially at this price tier. It added credibility to UGREEN’s claims of wanting to provide a more seamless and flexible user experience.

During the visit, I was repeatedly shown signs of a long-term strategy. While some early criticisms of UGREEN’s NAS rollout remain valid—particularly around the initial reliance on crowdfunding and uneven software features—the team seemed aware of these issues and determined to address them. There was no indication of a short product lifecycle.

In fact, staff emphasized that the current DXP models are not expected to receive a hardware refresh for at least two years. The focus in that window will be firmware updates, compatibility expansions, and building out features. The overarching message was clear: UGREEN wants to be seen as a top-tier NAS vendor within the next 3 to 5 years.

UGREEN is clearly taking its NAS division seriously. While this visit offered a curated look at their operations—something to be expected with any factory tour—the underlying infrastructure and approach felt well-considered. Unlike many brands that rely on OEM or white-label models, UGREEN appears to be building their NAS solutions from the ground up.

While the company didn’t confirm or deny third-party manufacturing partnerships, the focus on in-house software, R&D-heavy staffing, and direct integration of their own accessory ecosystem suggests a vertically integrated model. Based on what I observed, UGREEN isn’t simply experimenting with NAS—they’re actively investing in it as a long-term product category. Their roadmap may still be evolving, and the software isn’t yet on par with incumbents like Synology or QNAP, but their forward-looking approach and resource commitment imply they’re in it for the long haul.

Synology DS1825+ NAS Revealed – New 8 Bay NAS on the Block

Synology has quietly launched the new DS1825+ NAS, an 8-bay desktop solution aimed at prosumers, creative professionals, and small businesses in need of high-capacity, high-reliability network storage. Replacing the 2020-era DS1821+, this new model has debuted across eastern markets including Taiwan, Japan, China, and Australia, with broader availability expected within the coming month. While the DS1825+ shares the same AMD Ryzen V1500B processor as its predecessor, it introduces meaningful upgrades in system memory, network connectivity, and expansion port design. This release also reflects Synology’s increasingly closed hardware ecosystem approach, particularly in terms of drive compatibility. With pricing expected to be similar to the DS1821+—around $999 to $1099 USD—the DS1825+ positions itself as an incremental yet strategically significant refresh in Synology’s “Plus” lineup.

Synology DS1825+ NAS – Hardware Specifications

The DS1825+ is powered by the AMD Ryzen V1500B, a quad-core, 64-bit processor running at 2.2 GHz. This is the same CPU used in the DS1821+, and while it lacks a performance boost on paper, it continues to deliver reliable, multi-threaded performance suited for virtualization, large file transfers, and simultaneous user workloads. The system comes with 8 GB of DDR4 ECC SODIMM memory pre-installed, up from 4 GB in the DS1821+, and supports up to 32 GB across two slots. ECC memory adds an additional layer of data protection by automatically correcting memory errors—a key consideration for business-critical environments.

Synology DS1825+ NAS – DSM Software Specifications

The DS1825+ runs Synology’s DiskStation Manager (DSM), a Linux-based operating system that brings a wide array of software features designed for both home and business environments. Core functionalities include Synology Drive, which supports up to 100 users for cloud-style file syncing and sharing, and Synology Office, which enables real-time collaborative editing across documents, spreadsheets, and slides with similar user caps. For data protection, Snapshot Replication allows up to 256 snapshots per shared folder and 4,096 total system snapshots, while Hyper Backup and Active Backup for Business provide comprehensive options for client and server backups. Surveillance Station is also included with two default IP camera licenses and supports up to 40 1080p or 4K streams, depending on codec and frame rate, making it suitable for medium-scale surveillance setups.

One area where the DS1825+ makes a notable shift is in its storage pool policies. While the M.2 NVMe SSD slots can be used to create dedicated storage pools in addition to cache, this functionality is locked behind strict hardware validation. Only Synology-certified drives—specifically the SNV3400 series—are permitted for this role. This tighter integration may offer improved thermal management and reliability assurances but represents a step away from the broader compatibility seen in previous Plus-series devices.

Synology DS1825+ NAS vs the DS1821+ NAS

At first glance, the DS1825+ and DS1821+ appear nearly identical in core architecture, both using the AMD Ryzen V1500B processor and offering 8 drive bays with optional expansion to 18. However, the DS1825+ introduces several hardware-level improvements that cater to modern network environments. These include a bump in default RAM from 4 GB to 8 GB, upgraded LAN ports from four 1GbE to two 2.5GbE, and a shift from eSATA to USB-C-based expansion for DX525 units. These changes may not result in dramatically different performance under all conditions but do reflect a push toward better bandwidth utilization and a more consolidated hardware platform. Additionally, while the PCIe slot remains the same (Gen3 x8, x4 link), users looking to upgrade to 10GbE or 25GbE networking will benefit from increased LAN speed potential out of the box.

That said, the DS1825+ introduces certain trade-offs compared to its predecessor. While the DS1821+ maintained broader compatibility with third-party hard drives and SSDs, including full DSM functionality even with unverified drives, the DS1825+ enforces a stricter hardware compatibility policy. As a result, users are now limited to Synology-verified drives for core functions like volume creation and SSD caching. This shift may benefit system reliability and warranty alignment but could deter users with existing non-Synology storage media or those seeking cost-effective alternatives. Moreover, while the DS1825+ enables a higher potential single-volume size (200 TB with expanded memory), it actually reduces the number of internal volumes from 64 to 32, which may be a consideration for more advanced or segmented storage environments.

Synology DS1825+ NAS – Hard Drive Compatibility

With the release of the DS1825+, Synology has fully adopted its stricter hardware validation policy, significantly limiting support for third-party hard drives and SSDs. Unlike earlier models such as the DS1821+, which allowed DSM installation and storage pool creation with non-verified drives (albeit with warning messages), the DS1825+ enforces compatibility checks at the system level. Currently, only Synology-branded drives — such as the HAT3300 and HAT5300 series HDDs, and the SAT5200 and SNV3400 SSDs — are included on the official compatibility list. Attempts to install DSM with unverified HDDs, including popular models like the Seagate IronWolf and WD Red Plus, result in a complete block at initialization. There is no option to bypass or ignore these restrictions, and DSM will not proceed past setup when such drives are detected.

This strict policy has also been observed during storage expansion and migration. Migrated volumes from older Synology systems using unverified drives will still mount successfully on the DS1825+, allowing users to retain access to their data. However, the DSM interface will persistently display warnings, error icons, and status alerts across the Storage Manager and system health panels.

These alerts cannot be dismissed or suppressed, and while they do not affect system operation, they may be problematic for less technical users or managed IT environments. Furthermore, expanding an existing storage pool with unverified drives is no longer allowed — even if the new drives are identical to those already in use. Tests confirm that DSM will refuse to integrate non-listed drives into a pool, issue compatibility errors for hot spare assignments, and block recovery attempts for degraded arrays using unverified media.

One exception, as currently observed in testing, involves SATA SSDs. While unverified 3.5” HDDs are completely blocked from use during initialization, certain non-Synology SATA SSDs can still be used to install DSM or create volumes. These drives are flagged with warnings post-installation, but DSM allows the setup to proceed. That said, these SSDs also carry ongoing status alerts, and users cannot combine them with verified HDDs in mixed arrays or use them to expand verified pools. M.2 NVMe support is even more restrictive — only Synology SNV-series SSDs are accepted for either caching or pool creation, and all third-party models are entirely blocked. For now, users relying on legacy or third-party drives face a clear trade-off: adopt Synology’s ecosystem fully or accept a range of functional and visual limitations that reduce overall flexibility.

Synology DS1825+ NAS – Price and Release

The Synology DS1825+ is currently available only in select eastern regions, including Taiwan, Japan, China, and Australia, with broader global availability expected to follow within the next few weeks. Based on current distribution information, retail listings, and typical rollout timelines, availability in North America, the UK, and Europe is anticipated by the end of May or early June 2025. While Synology has yet to confirm official regional pricing, early indications suggest the DS1825+ will launch at approximately $999 to $1,099 USD—on par with the original MSRP of the DS1821+. This pricing strategy maintains Synology’s established positioning for its 8-bay “Plus” series NAS models, appealing to both advanced home users and small business environments looking for scalable, reliable storage solutions.

As with recent releases in the 2025 Synology lineup, prospective buyers should pay close attention to official announcements and trusted retailers, particularly in light of increasing emphasis on bundled hardware and reduced third-party flexibility. The DS1825+ introduces modest but meaningful hardware changes—such as default 8GB ECC memory, dual 2.5GbE LAN, and USB-C expansion support—while retaining the same core CPU. Although it lacks a generational leap in processing power, the unit aims to refine the overall platform rather than reinvent it. However, potential buyers should be fully aware of the enforced drive compatibility limitations, which mark a shift from previous models and may impact long-term upgrade plans. For those seeking a dependable NAS with improved baseline specs and tighter integration into the Synology ecosystem, the DS1825+ presents a balanced, if slightly more controlled, successor.

The Synology DS1525+ NAS is Confirmed and Just Overshadowed the DS925+

The Synology DS1525+ NAS represents a significant evolution in the brand’s 5-bay desktop series, bringing forward a more scalable, performance-focused solution aimed at both advanced home users and professional environments. Positioned as a more powerful and versatile alternative to the recently launched DS925+, the DS1525+ is clearly engineered with broader deployment scenarios in mind—from creative professionals handling high-volume media workflows to small businesses seeking reliable virtualization, backup, and collaboration tools. It boasts a modernized hardware foundation, including a Ryzen quad-core processor, 8GB of ECC memory (upgradeable to 32GB), dual M.2 NVMe SSD slots, and native support for 2.5GbE networking—features that now align with the increasing demands for multi-user, high-throughput environments.

Yet the DS1525+ isn’t just about faster networking or raw internal horsepower—it also brings back long-requested upgrade options like 10GbE scalability via a PCIe slot and dual DX525 expansion support for up to 15 drives total. This places the DS1525+ in a much more flexible tier compared to previous 5-bay Synology NAS systems and even challenges some of the lower-end rackmount models in terms of features and performance. With the continuing integration of Synology’s DSM 7.2 platform and a shift in how the brand is enforcing drive compatibility policies in the 2025 generation, the DS1525+ also enters the market during a controversial transition period for the company—something that may significantly influence buying decisions. Whether you’re upgrading from an older DS920+/DS1520+ or looking to deploy a scalable data solution for your home or office, the DS1525+ arrives at a pivotal moment for Synology.

Synology DS1525+ NAS – Hardware Specifications

The Synology DS1525+ brings a refined balance of processing power, memory, connectivity, and scalability that reflects its positioning in the upper end of Synology’s Plus Series. At its core is the AMD Ryzen V1500B processor, a 64-bit quad-core chip running at 2.2GHz with support for hardware encryption and virtualization. While this processor first debuted in Synology’s higher-end SMB models in 2020, its migration to the 5-bay desktop tier represents a welcome boost in capability for power users. It offers significantly more multitasking headroom compared to the dual-core Ryzen R1600 seen in the DS923+, and its support for native virtualization, container workloads, and file services under sustained loads makes it a particularly strong choice for office deployments and edge data processing.

The DS1525+ also introduces versatile storage configuration options. It supports five 3.5″/2.5″ SATA HDDs or SSDs, with the option to add two DX525 expansion units for a maximum of 15 bays total—translating to 300TB of raw capacity with 20TB drives. Additionally, the system includes two M.2 NVMe slots, allowing users to add SSD cache acceleration or create separate storage pools without sacrificing any of the main drive bays. As with other 2025-generation Synology models, the M.2 slots currently only support Synology’s own SNV-series drives for both caching and pool creation, further tying storage choices to the Synology ecosystem.

Network and expansion features on the DS1525+ are another standout area. The NAS includes two native 2.5GbE LAN ports that support Link Aggregation, failover, and SMB multichannel. This addresses a long-standing complaint of previous generations, which were limited to 1GbE by default. Better still, the DS1525+ includes a PCIe Gen3 x2 slot for installing Synology’s E10G22-T1-Mini 10GbE network card—something that was removed from the DS925+ entirely. This combination of faster default networking and optional 10GbE makes the DS1525+ suitable for demanding data workflows, such as multi-camera surveillance, real-time 4K media editing, and large-volume backup tasks.

Synology DS1525+ NAS vs the DS925+ (2025) or DS1522+ (2022)

The release of the Synology DS1525+ will naturally invite comparisons with two other key models in Synology’s portfolio: the recently launched DS925+ and the 2022-era DS1522+. On paper, the DS1525+ shares a large portion of its DNA with both of these models — borrowing the same AMD Ryzen V1500B processor from the DS925+, and directly succeeding the DS1522+ as Synology’s latest 5-bay NAS in the Plus series. But while these three models target similar audiences — advanced home users, creative professionals, and small businesses — there are clear differences in hardware, scalability, network architecture, and long-term usability that separate them meaningfully. The DS1525+ builds directly on the foundation laid by the DS925+, which itself introduced a wave of hardware upgrades to the Synology Plus series in early 2025. Both devices feature the same AMD Ryzen V1500B 4-core, 8-thread processor and support ECC memory up to 32GB. However, where the DS925+ stops at 4 bays with no support for expansion units, the DS1525+ supports up to 15 total bays with the inclusion of two DX525 expansion chassis — a major difference for users planning long-term storage growth. The DS1525+ also doubles the memory out of the box (8GB vs 4GB in the DS925+), includes the same 2x 2.5GbE ports for faster-than-gigabit networking, and features dual M.2 NVMe slots for cache or storage pools. In essence, the DS1525+ is the more scalable, robust choice — particularly if you foresee needing significantly more storage or concurrent users down the line.

The DS1522+, launched in mid-2022, was one of Synology’s most widely praised 5-bay NAS systems, with an excellent price-to-performance ratio. It featured the AMD Ryzen R1600 processor (dual-core, 4-thread) and came with 8GB of ECC memory, a PCIe Gen 3 slot for 10GbE upgrades, and four Gigabit Ethernet ports for flexible network configurations. The DS1525+ modernizes and refines that package. While it drops the PCIe slot, it replaces it with native 2.5GbE networking — removing the need for upgrades just to get faster-than-Gigabit speeds. It also improves processor efficiency with the more capable V1500B CPU (same as in the enterprise-grade DS1823xs+) and retains support for up to 32GB of ECC RAM. Additionally, the M.2 NVMe slots in the DS1525+ support both caching and storage pools — unlike earlier models where storage pool creation was either unsupported or limited to Synology-only drives.

Which of these NAS systems is right for you comes down to a blend of performance needs, scalability goals, and budget. The DS1525+ offers a more future-proof solution with high raw performance, 5-bay storage out of the box, superior expansion support (up to 15 drives), and a modern networking stack with 2.5GbE ports included as standard. It’s ideal for content creators with large media libraries, teams running shared services or VMs, or businesses needing long-term flexibility. The DS925+, on the other hand, is the budget-conscious user’s pick — priced lower and providing nearly identical internal hardware, but in a more compact 4-bay enclosure with no option to scale beyond that. If you’re confident you won’t need more than 4 drives and don’t require 10GbE or PCIe expansion, the DS925+ still provides DSM 7.2 and Synology’s excellent software ecosystem without compromise. Finally, for users still holding onto the DS1522+ or considering it due to its often discounted price post-DS1525+ launch, it’s worth weighing the trade-offs. While the DS1522+ provides a PCIe slot for 10GbE expansion, it lags behind in CPU power, lacks 2.5GbE out of the box, and doesn’t support NVMe storage pools. The DS1525+ is clearly the better long-term investment — if the price difference fits your budget. For users looking for the right balance of power, performance, and scalability — without needing to jump to the pricier XS series — it may well be the best 5-bay Synology NAS to date.

Synology DS1525+ NAS – HDD and SSD Compatibility

One of the biggest points of contention with the new Synology DS1525+ — following the controversy sparked by the DS925+ — is Synology’s stricter enforcement of drive compatibility. Historically, Synology supported a broad range of third-party hard drives and SSDs, merely issuing warning messages when unsupported drives were used. That changed with the DS925+, and the DS1525+ appears to double down on this new policy. At launch, the DS1525+ only lists Synology-branded HDDs and SSDs — such as the HAT3300, HAT5300, SAT5200, and SNV3400 — as officially compatible. If users attempt to initialize DSM using a drive not listed, the system will block installation entirely. This is a significant departure from earlier models like the DS1522+ or DS920+, which allowed DSM installation with third-party drives, even if accompanied by warning banners.

This tighter control extends to both SATA HDDs and M.2 NVMe SSDs. In the DS1525+, users can no longer use third-party NVMe SSDs for even basic caching — a feature previously accessible with non-Synology drives. Storage pools and caching are now restricted to Synology’s own SNV-series drives. This limitation can be a deal-breaker for users with existing SSDs or those seeking more affordable alternatives.

Drive migration from older NAS systems still works, with volumes booting as expected — but warning messages about unverified drives will be persistent. Moreover, trying to expand existing storage pools with unlisted drives will now fail outright, blocking the option in Storage Manager unless using Synology-verified models. While Synology cites system reliability and long-term support as reasons for these restrictions, the user base has expressed growing frustration. This new approach marks a clear shift toward a walled ecosystem, and while it may enhance stability, it reduces flexibility — especially for enthusiasts and IT professionals used to Synology’s former openness.

Synology DS1522+ NAS Release Date and Price?

The Synology DS1525+ NAS is expected to see a staggered global release, continuing the rollout pattern observed with the DS925+ and other 2025 series models. Initial availability is anticipated in Synology’s eastern markets — including Taiwan, China, Japan, Australia, and New Zealand — with Western availability (North America, UK, and Europe) likely landing in late May or early June 2025. This regional launch strategy has become common for Synology, allowing them to manage early feedback and firmware polishing before global distribution.

As for pricing, early indicators suggest that the DS1525+ will launch between $699 and $799 USD, depending on local taxes and bundled accessories (such as pre-installed memory or included drives). This places it squarely between the DS925+ ($599–$649) and the older DS1522+, which has often dipped below $550 in recent sales due to its older hardware and limited upgradability. Despite being the most expensive of the trio, the DS1525+ justifies its price tag with enhanced default memory, greater expansion potential, and retained PCIe support for optional 10GbE — features notably absent on the DS925+.

While Synology has yet to officially confirm regional pricing or exact release dates, retail listings and early distribution documents hint that pre-orders and launch events may begin rolling out in key Asian markets before the end of May. As always, early adopters should watch Synology’s official channels and trusted retailers for updates, especially considering recent trends toward drive bundling and tighter ecosystem control. For those who waited for a more robust refresh of the DS1522+, the DS1525+ is shaping up to be the spiritual and practical successor many had hoped for.

Le Synology DS925+ vient tout juste d’être lancé et nous vous proposons de le découvrir en avant-première. Ce nouveau NAS 4 baies marque un tournant décisif pour le fabricant, notamment en matière de stratégie produit et de compatibilité matérielle. Découvrez notre test complet…

Test Synology DS925+

La nouvelle série DSx25+ de Synology suscite de nombreux débats, principalement à cause de la restriction imposée à l’usage exclusif de disques durs et SSD de la marque. Le fabricant se veut rassurant en promettant la certification future d’autres disques, mais à ce jour, seuls les modèles Synology figurent sur la liste de compatibilité.

Contenu de la boîte

Commençons par découvrir le contenu de la boîte :

• Le DS925+ en lui-même ;
• 2 câble réseau RJ45 ;
• L’alimentation externe et son câble ;
• Les clés de verrouillage des disques ;
• Des vis pour les SSD ;
• Un QR code renvoyant vers le manuel en ligne ;
• Un livret sur la garantie/conformité.

Comme à son habitude, Synology fournit le strict nécessaire pour assurer le bon fonctionnement de l’appareil.

Construction du NAS et design

Le design du DS925+ reste fidèle à la tradition Synology : un boîtier compact en plastique noir, robuste, pesant environ 2,2 kg et mesurant 166 x 199 x 223 mm. À l’arrière, on retrouve deux ventilateurs de 92 mm, assurant une circulation de l’air dans le boitier.

Installation du NAS

L’installation des disques durs ne nécessite aucun outil, tout comme celle des SSD NVMe (accessibles sous le NAS). En revanche, un tournevis est requis pour les SSD SATA. Pas d’évolution de ce côté, c’est simple et rapide…

Compatibilité des disques et tensions

Le principal point de crispation concerne la compatibilité des disques. Synology impose désormais l’utilisation de disques durs et SSD certifiés (voir notre article). Pour l’instant, seuls les modèles de la marque sont officiellement compatibles. En cas de migration depuis un ancien NAS, le volume sera indiqué comme migré, mais Synology recommandera de remplacer les disques. Pour une nouvelle installation, il est impossible de créer un volume si les disques durs ne sont pas des Synology (lire notre dossier). À noter : l’utilisation de SSD d’autres marques permet de créer un volume, mais des avertissements s’afficheront pour vous inciter à les changer par des modèles certifiés.

Il existe néanmoins des solutions non officielles, comme le script 007revad. Ce dernier permet de faire reconnaître des disques tiers comme compatibles. Synology ne bloque pas encore cette méthode, mais le support technique pourrait limiter l’assistance en cas de problème de performance.

Connectique

Le NAS dispose des interfaces suivantes :

• 2 ports USB 3.0 Type-A (dont 1 à l’avant) ;
• 1 port USB 3.0 Type-C (pour une unité d’expansion) ;
• 2 ports réseau 2,5 Gb/s.

L’arrivée du Multi-Gig est appréciable, mais la disparition du port PCIe (présent sur le DS923+) empêche désormais l’ajout d’une carte 10 Gb/s… une régression pour certains utilisateurs. Synology passe enfin au 2,5 Gb/s en standard sur ses NAS, c’est une excellente nouvelle. Pour rappel, la concurrence le propose depuis 2019.

Intérieur du DS925+

Le DS925+ embarque un processeur Quad Core AMD Ryzen V1500B à 2,2 GHz, déjà utilisé sur les modèles DS1621+ et DS1821+ (sortis en 2020). Il est épaulé par seulement 4 Go de RAM DDR4 ECC, extensible jusqu’à 32 Go. Ce processeur ne dispose pas d’iGPU et  a obtenu un score de 4829 points selon Cpu Benchmark. L’absence d’évolution matérielle notable est regrettable, surtout en 2025, face à une concurrence qui innove davantage.

DSM 7.2

Le NAS est livré avec DSM 7.2, la dernière version du système Synology. Au moment où nous écrivons ces lignes, rien n’indique qu’une nouvelle version majeure soit en approche.

L’interface reste soignée, performante et adaptée aux besoins des professionnels comme des particuliers. L’accent est mis sur la sécurité des données et la convivialité, des atouts qui continuent de séduire. Il faut bien l’avouer, DSM reste encore au-dessus du lot. Cependant, la concurrence se fait de plus en plus pressante… L’écosystème complet Synology va-t-il continuer de séduire ?

Performances du DS925+

Dans la première partie des tests, nous allons évaluer les performances des transferts à travers un réseau 2,5 Gb/s (entre le NAS et des ordinateurs). Ensuite, nous regarderons les capacités du processeur, en analysant ses performances dans la virtualisation et le transcodage vidéo… même si ce NAS ne devrait pas offrir de grandes surprises.

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 de ces 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 DS925+, nous avons configuré un premier volume avec 2 SSD NVMe en RAID 0, puis en RAID 0 avec le chiffrement des données. Nous continuerons avec 3 SSD SATA en RAID 5. Enfin, nous finirons avec le RAID 0 et 2 câbles réseau.

RAID 0 (1 seul câble)

Le Synology DS925+ offre des performances bien équilibrées. On remarque immédiatement les bienfaits du 2,5 Gb/s, mais on s’attendait à dépasser les 300 Mo/s dans nos tests… Malheureusement, ce ne fut pas le cas.

RAID 0 + Crypt (1 seul câble)

Avec le chiffrement des données, le DS925+ s’en sort très bien. L’impact en écriture reste faible… ce qui est plutôt rare.

RAID 5 (1 seul câble)

Avec le volume en RAID 5 (SSD SATA), le Synology reste dans la cohérence et les performances sont au rendez-vous.

RAID 0 (2 câbles)

En utilisant 2 câbles et en activant le SMB Multichannel, il est en théorie possible de doubler les débits.

Comme vous pouvez le constater, s’il y a un gain sur les débits en lecture. Cependant, les performances en écriture sont moins bonnes, notamment sur les petits fichiers.

Performances globales

Tout d’abord, il convient de rappeler que le DS925+ est équipé d’un processeur AMD Ryzen dépourvu d’iGPU, ce qui rend impossible le transcodage vidéo matériel avec des applications comme Plex ou Jellyfin. Cette limitation peut s’avérer pénalisante pour certains usages multimédias. En revanche, lors de nos tests, aucune latence ni difficulté particulière n’a été constatée lors de l’exécution de machines virtuelles (par exemple sous Linux) ou de conteneurs Docker… Le processeur offre de bonnes performances globales.

Consommation électrique et nuisance sonore

Les deux ventilateurs (92 mm) sont relativement silencieux. Il faudra vous rapprocher à moins d’un mètre pour les entendre. En utilisation normale avec 3 SSD SATA et 2 SSD NVMe, la consommation électrique varie entre 17 et 18 W. Lors de transferts intensifs avec chiffrement des données ou le transcodage logiciel, elle ne dépasse pas 27 W.

Le Lockerstor 4 Gen3 (AS6804T) d’ASUSTOR est un NAS 4 baies haut de gamme destiné aux utilisateurs exigeants. Il est équipé d’un processeur AMD Ryzen V3C14 capable d’atteindre 3,8 GHz et de 16 Go de mémoire. Ce NAS promet des performances de très haut niveau. Cependant, son prix le destine plutôt au mon de de l’entreprise. Rentrons immédiatement dans le vif du sujet…

Test de l’ASUSTOR AS6804T

Cela faisait plusieurs mois que nous attentions avec impatience ce nouveau NAS. Le boitier s’adresse aux utilisateurs les plus exigeants, qu’ils soient professionnels ou passionnés de technologie. Sur le papier, il faut avouer qu’il a tout pour plaire… voire un peu plus.

Contenu de la boîte

Commençons par découvrir le contenu de la boîte :

• L’AS6804T en lui-même ;
• 4 câble réseau RJ45 Cat.6 ;
• Des vis de fixation pour les disques/SSD ;
• L’alimentation externe avec son câble ;
• Un guide de démarrage rapide ;
• Un livret de garantie.

La présence de 4 câbles réseau Cat.6 est une excellente surprise, mais 2 auraient été suffisant. En revanche, Asustor ne fournit pas de dissipateurs thermiques pour les SSD NVMe, ce qui peut sembler regrettable étant donné la sensibilité de ces supports à la chaleur.

Design et connectivité

Le châssis en métal du Lockerstor 4 Gen3 inspire confiance.  La ventilation est assurée par un ventilateur de 120 mm à l’arrière et un caloduc en cuivre dédié au refroidissement du processeur. En façade, on retrouve 4 emplacements pour disques durs (ou SSD SATA), ainsi qu’un écran LCD deux lignes, qui accentue l’orientation professionnelle du produit.

Sur le plan de la connectivité, il offre :​

• 2 ports 10 Gb/s RJ45 ;
• 2 ports 5 Gb/s RJ45 ;
• 2 ports USB4 (type C)* ;
• 3 ports USB 3.2 Gen 2 (type A) dont 1 en façade.

La connectique est de très haut niveau avec ces nombreux ports réseau (10 Gb/s et 5 Gb/s) et tous ces ports USB haute vitesse. Forcément, cela se ressent dans le prix de ce produit.

À noter : aucune sortie HDMI sur ce modèle, ce qui pourrait en surprendre plus d’un. Nous y reviendrons.

* Attention, les ports USB4 sont limités. Par exemple, il n’est pas possible d’y connecter un PC/NAS directement, ni de carte graphique externe (eGPU).

Intérieur du AS6804T

Passons à l’intérieur du NAS… Tout d’abord, on y trouve 4 emplacements M.2 NVMe PCIe Gen 4 (x1) pour SSD​ ultrarapide. Nous reviendrons sur les performances un peu plus loin. Le NAS est construit autour d’un processeur Quad-Core AMD Ryzen V3C14 cadencé à 2,3GHz (avec un mode turbo jusqu’à 3,8 GHz). Un choix intéressant de la part d’Asustor, mais ce dernier ne dispose pas d’iGPU (carte graphique intégrée)… cela limite les capacités de transcodage vidéo matériel et explique l’absence de sortie HDMI. Le NAS est livré avec 16 Go de RAM ECC DDR5 (extensible jusqu’à 64).

Pour information, ce processeur obtient un score de 11 882 points selon CPU Benchmark (avec une marge d’erreur). C’est un très haut niveau… À titre de comparaison, l’AMD Ryzen V1500B a un score de 4 829 points (le processeur du DS925+ de Synology).

Il est important de noter la présence d’un emplacement PCIe 4.0, pour une carte réseau uniquement selon le fabricant. Le NAS dispose déjà de 4 ports réseau, on peut s’interroger sur la nécessité d’en ajouter encore un cinquième. Mais ne jugeons pas, il y a peut-être de la demande… la possibilité d’installer une petite carte graphique aurait aurait été une alternative bienvenue.

Installation du NAS

L’installation est simple et efficace. Les disques durs 3,5″ se montent sans outils. Pour les disques 2,5″, comme les SSD SATA, des vis sont fournies. Le fond du boîtier est renforcé pour amortir l’insertion des disques, un détail important notamment pour la fonction MyArchive.

Asustor ne fournit pas de radiateur pour les SSD NVMe, contrairement à d’autres fabricants. C’est dommage, car la chaleur est l’ennemi des performances de ces supports de stockage. La ventilation du boîtier reste cependant efficace.

ADM 5.0

Les NAS de la série Lockerstor Gen3 sont les seuls à pouvoir bénéficier d’ADM 5.0. Les autres NAS sont encore en version ADM 4.3 officiellement, au moment où sont écrites ces lignes.

ADM 5.0 est une mise à jour importante au regard de sa numérotation. Voici quelques améliorations importantes :

• Mise à niveau du noyau Linux vers la version 6.6 LTS avec de nombreux correctifs de sécurité
• Mises à jour d’OpenSSL pour améliorer la compatibilité et les performances
• SMB Multi-Channel passe (enfin) en version stable
• Améliorations de l’expérience utilisateur :
  • La barre d’outils ADM peut être masquée automatiquement
  • ADM adopte par défaut la langue du navigateur
  • Mise à jour des options régionales et des fuseaux horaires
  • Affichage optimisé du Gestionnaire de stockage pour une lecture plus efficace des informations

L’interface a subi quelques retouches ici et là, mais rien de vraiment révolutionnaire… d’un autre côté, Asustor nous a habitués aux fils des années à opérer seulement à des petites touches. L’ensemble est stable, fonctionnel et rapide.

On appréciera l’accompagnement au premier démarrage qui est d’excellente qualité, que nous vous recommandons de suivre. S’il peut sembler un peu intrusif, il est essentiel pour mettre en place les bonnes pratiques : stockage, partage et sécurité.

Par contre, nous avons noté quelques petits bugs notamment d’affichage. Rien de vraiment bloquant, mais ils peuvent être gênant. Un redémarrage du NAS a corrigé la plupart des soucis rencontrés.

On a particulièrement apprécié l’arrivée d’un éditeur de texte dans ADM et qu’il est possible de lancer directement depuis l’Explorateur de fichiers intégré.

Performances de l’AS6804T

Pour la première partie de nos tests, nous allons évaluer les performances des transferts à travers un réseau 10 Gb/s (entre le NAS et des ordinateurs). Ensuite, nous analysons les capacités du processeur et plus particulièrement ses performances de virtualisation et de transcodage vidéo.

Vitesses dans les transferts

Depuis plusieurs années, nous avons mis en place un protocole de tests rigoureux pour fournir 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 dans un second temps 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 partir de ces tests, nous calculons une moyenne des transferts que nous représentons sous forme de graphiques, exprimée en mégaoctets par seconde. Plus le nombre est élevé, plus le NAS est rapide. Pour nos tests avec l’ évaluation de l’AS6804T, nous avons configuré un premier volume avec 2 SSD NVMe en RAID 0, puis en RAID 5 avec 3 SSD en RAID 5. Nous avons utilisé des WD Red SN700, certainement les meilleurs de leur catégorie.

RAID 0

En lecture, le NAS dépasse les 1000 Mo/s sans difficulté. En écriture, les performances sont un peu en retrait, mais restent excellentes.

RAID 0 avec le chiffrement activé

La lecture reste rapide, mais l’écriture chute à environ 300 Mo/s. Cela reste acceptable, mais en deçà de nos attentes.

RAID 5

Très bon niveau global, mais les performances ne franchissent pas un nouveau cap malgré l’utilisation de SSD NVMe et du 10 Gb/s. Nous sommes cependant dans le haut du panier.

Performances générales de l’AS6804T

Le processeur AMD Ryzen V3C14 s’en sort remarquablement bien sur les tâches complexes : chiffrement, machines virtuelles, conteneurs Docker, etc. Côté puissance brute, rien à redire. En revanche, l’absence d’iGPU rend le transcodage vidéo matériel impossible. Pour les flux Ultra HD/4K via Plex ou Jellyfin, cela fonctionnera suivant le périphérique utilisé pour le décodage (côté client). Nous n’avons pas réussi à le mettre en porte-à-faux.

Consommation électrique et nuisance sonore

Le ventilateur (120 mm) reste relativement discret, bien qu’audible à proximité. Côté consommation électrique, en utilisation normale avec 3 SSD, elle varie entre 15,5 et 16,1 W. Lors de transferts intensifs avec chiffrement ou transcodage, elle ne dépasse pas 35,5 W.

Here’s what we’ve confirmed so far in the tests as of 07/05/25:

Using Synology 1st Party Drives – Everything Works as Expected

If you’re using Synology-branded HDDs or SSDs, then your experience on the DS925+ will be completely normal.

System initialization, DSM installation, storage pool creation, and all other operations work exactly as they always have, with no warnings, compatibility errors, or feature restrictions. This includes both the Plus series (e.g., HAT3300/HAT3310) and the Enterprise-class HAT5300 drives.

These drives are the only ones currently listed as fully supported on the official compatibility list for the DS925+, and this exclusive support ensures full DSM integration, performance monitoring, and system health reporting. If you’re a first-time buyer who’s starting from scratch, and you’re willing to buy fully into the Synology ecosystem, this route remains the most seamless — albeit more expensive — option.

---

New Installations Blocked for Non-Verified Drives

As discussed in our NASCompares coverage and testing videos, attempting to initialise the DS925+ with hard drives that are not on the 2025 series compatibility list will block you from even starting DSM installation.

Below is the Synology DS925+ HDD Compatibility as of 3rd May 2025

This marks a major departure from Synology’s previous approach in DSM 7.0 and 7.1, where unsupported drives could still be used — though users would receive warnings in Storage Manager.

Below is the Synology DS923+ HDD Compatibility for comparison

Now, if you’re using unverified HDDs (such as Seagate IronWolf or WD Red Plus), the DS925+ will not proceed past the initial setup.

You’ll receive a message informing you that the drive is not compatible, and DSM cannot be installed. There’s no bypass, workaround, or “install anyway” option — and this applies even if the drives are physically identical to previously approved models.

This new and more limited approach (at least at the time of writing) raises concerns for home and business users alike who have previously relied on mixing and matching their preferred HDD brands with Synology hardware.

Drive Migration from Older Synology NAS – It Works, But Comes with Warnings

If you already own a Synology NAS and are planning to migrate your storage pool from an older system to the DS925+, you’ll be able to do so — even if your drives are no longer listed as compatible on the newer system.

DSM will recognize the array, import the configuration, and boot the system using your original DSM setup.

However, the entire system will then display a persistent series of warnings and error states, including amber and red icons in Storage Manager, drive health indicators marked “At Risk,” and compatibility warnings across the interface.

While everything technically works, the interface becomes visually and functionally “noisy.” For system integrators or IT administrators, this is especially important — your clients may perceive something is seriously wrong with the NAS even when the system is healthy.

It’s recommended to proactively inform any end users or clients about these warnings post-migration, to avoid unnecessary concern or support tickets. Synology has not yet provided a method to suppress or acknowledge these warnings permanently.

---

SATA SSDs Seem to Bypass the Block – But Still Carry Warnings

One of the more surprising findings in our testing was that SATA SSDs, even when not listed on the official compatibility list, were still able to initialize the DS925+ and allow DSM to be installed.

We tested this with several models, and the installation process continued normally — a stark contrast to the hard stop experienced with unverified HDDs.

However, this partial loophole comes with a catch. Once DSM is up and running, the system flags the non-verified SSDs the same way it flags migrated drives, with warnings in Storage Manager and ongoing notifications.

So while you can proceed, you’ll still be treated to that same red and amber text throughout your DSM environment. Still, for users willing to tolerate the interface alerts, this may provide an interim solution — especially for those who prefer SSDs for quiet, low-power deployments.

---

Expanding Existing Storage Pools with Unverified Drives is Blocked

Another key limitation to note is that you cannot expand an existing storage pool using unverified drives — even if your system was initialized using fully supported drives.

We tested this by creating a pool with Synology-approved HDDs, then attempting to add a non-Synology drive as an expansion. While the drive appeared in Storage Manager as “available,” the system refused to proceed with the expansion, citing that the drive was not verified or supported.

This strict enforcement essentially locks users into an all-or-nothing ecosystem. There’s no flexibility to upgrade later using lower-cost or readily available drives unless Synology chooses to add them to the compatibility list down the line.

---

M.2 NVMe Drives: No 3rd Party Support for Caching or Storage Pools

Historically, Synology has limited M.2 NVMe storage pools to their own SNV SSDs, but allowed third-party drives for read/write caching. That has now changed in the DS925+ and, presumably, all 2025 series models moving forward.

Our testing confirmed that non-Synology NVMe SSDs are no longer usable at all — neither for caching nor for creating storage pools.

Attempting to configure third-party NVMes results in the same hard block and error messages as unsupported HDDs. At the time of writing, only Synology SNV3400 and SNV3410 drives are listed as supported — both of which are tuned more for endurance than performance, making them a questionable fit for cache-centric workflows.

Pool Expansion Using a 4TB Seagate IronWolf Drive

We attempted to expand the existing migrated RAID pool with an additional 4TB Seagate IronWolf drive (same model, also verified on the DS923+). The drive was physically detected, appeared in Storage Manager, but the system refused to proceed with expansion.

System Message: The additional drive was flagged as incompatible, and any attempt to integrate it into the existing RAID resulted in an error stating that the media is not suitable or not verified. However, if your migrated pool is using SATA SSDs (or you setup the system with unverified SATA SSDs, which is still possible at the time of writing) you CAN expand the pool with likewise SATA SSDs.

Conclusion: The DS925+ does not permit expansion of an existing pool using unverified drives if you are using unverified HDDs, even if the original array consists of the exact same drive model. But SATA SSDs still allow this feature at the moment.

---

Pool Expansion Using a 4TB Seagate IronWolf Drive

What if you are using an existing pool that is made up of verified HDDs on the NAS (i.e drives from Synology or drives that are now on the verified compatibility list), but also want to create a 2nd pool, made up of unverified SATA HDDs or SATA SSDs?

Result: As expected, if you use SATA HDDs, then you can ONLY create a new separate pool using verified HDDs. However, SATA SSDs still allow for unverified SSD pools.

Hot Spare Addition Attempt Using Seagate IronWolf Drive

We repeated the process above but this time attempted to add a likewise Seagate IW 4TB drive as a Hot Spare.

Result: Just like the pool expansion test, the additional drive was visible but flagged as unsupported, and DSM blocked any attempts to add this as a failover Hot Spare repair drive with the migrated array.

Recovery of Degraded RAID Pool Using Seagate IronWolf Drive

To test RAID recovery, one of the three IronWolf drives in the migrated SHR array was removed, placing the system into a degraded state. We then inserted a fresh 4TB Seagate IronWolf drive.

Result: DSM detected the new drive but refused to initiate RAID rebuild, citing unsupported media.

Conclusion: Recovery of a degraded array using a Seagate IronWolf drive (unverified for DS925+) is not permitted — even when it’s the same model previously used in the pool.

Drive Removal and Reintroduction to Pool

Lastly, we removed one of the IronWolf drives from the active pool and reinserted it a few minutes later. This drive was part of the original migrated SHR setup.

Result: DSM re-added the drive without issue, recognizing it as part of the existing array. No rebuild or repair was needed, and the system returned to normal status — albeit still with the usual compatibility warnings.

Conclusion: Previously initialized and migrated drives will be accepted back into the same array, provided their identity matches the original configuration. However, these reinserted drives remain flagged as unverified.

Background: How Synology Got Here

At the time of writing this review, Synology is seemingly waging a war on unverified third-party drives being used inside their systems. Back in 2020/2021, Synology began rolling out their own range of storage media for use in their systems — starting with SSDs and eventually expanding to a range of 3.5-inch server-class and enterprise storage-class hard drives. Over the years, we have seen the brand begin to reduce the number of third-party drives listed as certified and verified for use in the DSM platform and in their NAS server devices. This duality — of promoting their own storage media while supporting third-party drives — has had its balance shifted considerably over the last two major Synology generations and across several updates in DSM.

In 2022, when the brand rolled out an update in DSM 7.1 that changed the system status for any NAS using non-Synology-approved drives to display a warning state, the wider Synology user base was in uproar. Synology would eventually roll this back and, although they never reversed the policy of warning users that their drives were not on the compatibility list, they did soften the system’s response. Fast forward to now, and the brand is again changing its third-party drive verification and compatibility methodologies internally. The 2025 series and onward will strictly require drives that are already listed on Synology’s compatibility list. Why is that a problem? Well — twofold. First, right now only Synology HDDs and SSDs are listed on the official DS925+ compatibility pages, despite the hardware inside the DS925+ being identical to previous Synology hardware from both the 2020 and 2023 generations. Second, Synology’s aggressive approach to enforcement. Previously, users could proceed with installation and simply be warned later. Now, installation is entirely blocked.

This will no doubt be problematic with e-retailers and online dealers unless they make this strict compatibility policy exceptionally clear. The rollout has been inconsistent and unclear at best. It first emerged via a press release on Synology’s German website, and the DS925+ page remains vague on the specifics. It might well be that weeks or months from now, the list of drives supported on the Synology DS925+ and other 2025 NAS systems will expand to include more third-party media. Nevertheless, the messaging has been profoundly unclear. If Synology’s verification tests have changed, they need to clearly explain how and why. If they have reported failures with unverified drives, those results should be shared. In discussions with numerous users online, many agree that Synology is walking a confusing line. Either fully embrace third-party drives as before — or bundle your own media and commit to it. Don’t sit in the middle.

Future Expansion & Unanswered Questions

Synology has stated that it is working with Western Digital, Seagate, and others to test and certify additional drives for use in the 2025 series. However, they also clarified that the responsibility for verification now lies more with the drive manufacturers, not Synology themselves. This means the pace and outcome of compatibility expansion are largely out of users’ hands — and still leaves early adopters in a restrictive position. We’ve already seen similar policies with M.2 NVMe SSDs in the 2023 generation — only allowing storage pool deployments if you use Synology-branded drives. And while DSM still supports caching with third-party drives in those older systems, that flexibility has now been removed in the 2025 series.

---

Conclusion – CHECK DRIVE COMPATIBILITY BEFORE YOU BUY!!!

The Synology DS925+ is a great piece of hardware in many respects, but it arrives with a much more locked-down approach to storage media than any Plus series NAS before it. Users hoping to reuse existing drives, mix-and-match HDDs for flexibility, or use cost-effective SSDs and NVMes from other brands need to reconsider their storage strategy or prepare for an ecosystem that’s increasingly closed. We’ll continue to test newer Synology 2025 devices as they launch and will update this article as compatibility lists evolve and behaviors change. But for now, if you’re planning to buy into this generation — and especially if you need to build on a budget — be aware: the HDDs you might WANT to buy might not be usable with your system – SO CHECK THE COMPATIBILITY PAGES FIRST!.

Stay tuned for more deep-dive comparisons, migration tutorials, and drive compatibility experiments right here at NASCompares. In the meantime, if you are considering purchasing an older generation Synology NAS that has more open and established storage media compatibility, below is a comparison of the Synology DS923+ from 2022/2023 and the new 2025 DS925+ NAS.

OLD Synology vs NEW Synology (DS923+ vs DS925+)

Reasons to Buy the Synology DS923+

Reasons to Buy the Synology DS925+

Faster 2.5GbE Networking Out-of-the-Box – Dual 2.5GbE ports offer higher baseline network speeds (up to 6Gbps aggregated), doubling the network performance compared to the DS923+ without requiring expansion cards. More Powerful Processor (More Cores/Threads) – The V1500B CPU offers 4 cores and 8 threads, delivering superior multitasking and heavier workload handling, especially for virtual machines, multiple users, and simultaneous services. Quieter Operation – The DS925+ operates at a lower idle noise level (20.5 dB vs 22.9 dB), making it better suited for office, home office, or studio environments where sound matters. Higher User and Service Limits – Thanks to the more powerful CPU, the DS925+ supports more Synology Drive users, Synology Office users, Synology Chat users, more concurrent SMB connections, and more virtual machines than the DS923+. Better Out-of-the-Box Experience – With stronger networking, higher multi-threaded performance, and no need for immediate upgrades, the DS925+ is ready to deliver higher performance without any additional investment, perfect for users who want maximum capability from day one.

PCIe Expansion for 10GbE Upgrades – The DS923+ features a PCIe Gen3 x2 slot, allowing users to install a 10GbE network card later, massively boosting network speeds beyond the built-in 1GbE ports. Broader 3rd-Party Drive Compatibility – Unlike the DS925+, the DS923+ allows full system initialization, storage pool creation, and DSM services even with non-Synology hard drives and SSDs—giving users more flexibility and choice. Lower Power Consumption and Heat Output – The DS923+ is slightly more energy-efficient in both active use and hibernation modes, making it a better fit for always-on environments where power savings add up over time. Potentially Lower Price (Especially Post-DS925+ Launch) – As the newer DS925+ replaces it, the DS923+ is likely to see discounts and wider availability, offering excellent value for budget-conscious users without sacrificing capability. Ideal for Customization and Long-Term Scalability – With the ability to upgrade the network, use a wider range of drives, and maintain full DSM functionality, the DS923+ is better suited for users who plan to evolve their setup over time.

In practical terms, the DS925+ is the stronger out-of-the-box choice, especially for users who value simplicity, improved default performance, and do not anticipate needing higher-than-2.5GbE networking down the line. However, the long-term value proposition becomes murkier when you factor in the DS923+’s PCIe expansion, broader drive compatibility, and the potential price drops that will follow its ageing status in Synology’s lineup. In short, the DS925+ is the better NAS on day one—more powerful, faster, and quieter. But if you’re planning for day 1,000, it’s worth pausing to consider whether the expandability and media flexibility of the DS923+ may be a better fit for your storage and networking needs over the next five to seven years.

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
