Grâce à la reconnaissance optique de caractères (OCR), il est possible de retrouver des textes présents dans des images ou des documents scannés. De plus, l’IA génère des descriptions d’images basées sur les scènes, objets ou thèmes, facilitant ainsi la recherche de photos à partir de requêtes telles que « lever de soleil à la plage ».

L’ensemble du processus d’indexation et de recherche s’effectue localement sur l’ordinateur de l’utilisateur, garantissant ainsi la confidentialité des données. Cette approche « local first » répond aux préoccupations croissantes concernant la protection de la vie privée et l’utilisation des données personnelles.

Compatibilité et exigences techniques

La version bêta de BeeDrive 2.0 est actuellement disponible pour les utilisateurs de macOS 15 ou supérieur, équipés de puces Apple Silicon et disposant d’au moins 16 Go de RAM. La prise en charge de Windows est prévue ultérieurement. Le moteur Deep Search prend en charge plusieurs formats de fichiers : PDF, DOCX, PPTX, JPG, PNG, HEIC et certains fichiers RAW. Il est également capable de gérer des fichiers dans différentes langues, dont le français, l’anglais, l’allemand et le japonais.

Une solution de stockage polyvalente

Au-delà de ses nouvelles capacités de recherche, BeeDrive reste un dispositif de stockage direct (DAS) performant, offrant jusqu’à 4 To de capacité via une connexion USB 3.2 Gen 2. Il permet la sauvegarde automatique des ordinateurs, le transfert de fichiers depuis les appareils mobiles (grâce à la fonction BeeDrop) et la synchronisation de dossiers. Sa conception compacte et légère en fait un outil idéal pour les professionnels en déplacement ou les particuliers souhaitant sécuriser leurs données sans dépendre du Cloud.

Une stratégie tournée vers l’IA

Le lancement de Deep Search s’inscrit dans une stratégie plus large de Synology visant à intégrer l’intelligence artificielle dans ses produits. Après l’introduction de l’AI Console pour DSM & MailPlus et l’annonce d’améliorations à venir pour la suite Office, BeeDrive devient le dernier produit en date à bénéficier de ces avancées technologiques. Cette orientation vers l’IA démontre la volonté de Synology de rester à la pointe de l’innovation tout en répondant aux besoins croissants de ses utilisateurs en matière de gestion intelligente et sécurisée des données.

En proposant une solution alliant performance, confidentialité et intelligence, Synology confirme sa position de leader sur le marché du stockage personnel et professionnel. Avec BeeDrive 2.0, l’entreprise offre une réponse concrète aux défis posés par la gestion croissante des données numériques. Si seulement le Deep Search pouvait arriver sur nos NAS…

Synology DS1525+ vs DS1522+ NAS Comparison – Get It Right, FIRST TIME!

With the arrival of the Synology DS1525+ in 2025, many users are now weighing it against its immediate predecessor, the DS1522+, released in 2022. On the surface, both NAS units share the same 5-bay form factor, nearly identical chassis design, and very similar price points—typically between $699 and $799 at launch. However, a deeper dive reveals a number of meaningful changes in hardware resources, storage expansion policies, and how Synology now handles drive compatibility and system flexibility. While the DS1525+ does offer better networking and CPU core count, it also introduces tighter restrictions on what drives can be used, how storage pools are formed, and what options are available to users looking to migrate data from older systems. By contrast, the DS1522+ retains a far more open approach to hardware, offering greater freedom for enthusiasts and IT professionals. In this article, we’ll break down the internal hardware, ports, storage support, DSM software capabilities, and system behavior of these two NAS systems—giving you the context you need to make the right decision the first time, and avoid buyer’s regret later.

Synology DS1525+ vs DS1522+ NAS Comparison – Internal Hardware

The most noticeable hardware difference between the DS1525+ and DS1522+ lies in their processors. The DS1522+ is powered by a dual-core AMD Ryzen R1600 CPU, which operates at a base frequency of 2.6 GHz and can boost up to 3.1 GHz. This chip delivers strong single-threaded performance and is very power efficient, making it well-suited for environments where tasks are sequential or lightly parallelized—such as SMB file sharing, surveillance, or general-purpose storage. The DS1525+, in contrast, uses a quad-core AMD Ryzen V1500B processor running at a fixed 2.2 GHz. While it lacks boost frequency, the additional cores and threads make it the more capable option for multitasking-intensive DSM deployments. Workloads like hosting multiple Docker containers, running several VMs, or operating high-volume backup jobs are handled more smoothly by the V1500B thanks to its stronger concurrent throughput. While synthetic benchmarks might show the R1600 ahead in single-threaded operations, in day-to-day NAS usage, the V1500B’s multitasking benefits are more relevant—particularly for users aiming to centralize many services on one box.

Synology DS1525+ vs DS1522+ NAS Comparison – Ports and Connections

The differences between the DS1525+ and DS1522+ become more apparent when examining their networking and expansion connectivity. The DS1522+ is equipped with four 1GbE RJ-45 LAN ports, which support link aggregation for up to 4 Gbps combined bandwidth when used with a managed switch. This configuration provides solid redundancy and flexible port allocation, especially for environments where isolating traffic across different services (e.g., backups, media, surveillance) is desirable. However, in 2024 and beyond, 1GbE is increasingly viewed as a bottleneck—particularly for users working with 4K video editing, large VM images, or fast local backups. The DS1525+ addresses this issue by shifting to 2 × 2.5GbE RJ-45 LAN ports, allowing up to 5 Gbps total bandwidth through link aggregation, and faster speeds on a per-connection basis, even when using unmanaged 2.5GbE switches that are now more common and affordable. This change aligns the DS1525+ with modern mid-tier NAS expectations and offers improved real-world performance, especially for multi-user workloads and high-speed transfers from SSD caches or NVMe pools.

Feature	Synology DS1522+	Synology DS1525+
LAN Ports	4 × 1GbE RJ-45	2 × 2.5GbE RJ-45
Link Aggregation / Failover	Yes	Yes
USB Ports	2 × USB 3.2 Gen 1	2 × USB 3.2 Gen 1
Expansion Ports	2 × eSATA (for DX517)	2 × USB Type-C (for DX525)
PCIe Slot	1 × PCIe Gen3 x2 (for 10GbE upgrade)	1 × PCIe Gen3 x2 (for 10GbE upgrade)
Wake on LAN / WAN	Yes	Yes
Scheduled Power On / Off	Yes	Yes
Hot-Swappable Drive Bays	5 × SATA HDD/SSD (M.2 not hot-swappable)	5 × SATA HDD/SSD (M.2 not hot-swappable)
M.2 NVMe Slots	2 × M.2 2280 (cache only, 3rd-party SSDs supported)	2 × M.2 2280 (cache and storage, Synology SSDs only)
Expansion Compatibility	DX517 (eSATA interface)	DX525 (USB-C interface)

In terms of USB connectivity, both models include two USB 3.2 Gen 1 ports, suitable for attaching external drives, UPS units, or compatible USB printers. These ports remain unchanged between models and offer no direct performance advantage to either system. Where the expansion capability does change significantly is in the port type for connecting additional storage enclosures. The DS1522+ includes two eSATA ports, allowing it to connect up to two DX517 expansion units, adding 10 more drive bays. The DS1525+, however, replaces these with two USB Type-C expansion ports, which interface with the newer DX525 expansion units. While the overall expansion capacity remains the same (15 total bays), the move to USB-C reflects a generational shift in Synology’s design language. USB-C may offer slightly more flexible cable routing and future-proofing, but it also introduces a hard cutoff between older and newer ecosystems. For users with existing DX517s or other eSATA-based gear, this limits backwards compatibility and locks the DS1525+ into the latest hardware infrastructure.

Additionally, both units include a PCIe Gen3 x2 slot for optional 10GbE network upgrades. Synology’s E10G22-T1-Mini card is supported on both models and provides a compact, cost-effective way to future-proof network performance. However, given the DS1525+ already starts with 2.5GbE, users may find less urgency to upgrade immediately compared to the DS1522+, where a 10GbE card may be needed sooner to break past 1GbE limitations. Both models support Wake-on-LAN and scheduled power events, and both feature dual rear fans for effective cooling regardless of network traffic or drive load. From a connectivity standpoint, the DS1525+ represents a forward step toward higher-speed networking and modern expansion methods—but it does so at the cost of legacy compatibility, which may matter for users with established infrastructure. In contrast, the DS1522+ offers broader port coverage and flexibility but risks becoming dated more quickly in high-throughput environments.

Synology DS1525+ vs DS1522+ NAS Comparison – Storage

At first glance, storage capacity and physical layout appear virtually identical between the DS1525+ and DS1522+. Both systems offer five main drive bays that support 3.5″ SATA HDDs and 2.5″ SATA SSDs, as well as two M.2 NVMe SSD slots for caching or, in the case of the DS1525+, full storage pool creation. Each NAS can be expanded up to a total of 15 bays using two proprietary Synology expansion units (DX517 for the DS1522+, DX525 for the DS1525+), enabling up to 240 TB of raw storage assuming maximum capacity drives. However, a major divergence emerges when we examine drive compatibility policies. The DS1522+ follows Synology’s older, more permissive approach: users may install third-party drives from brands like Seagate, Western Digital, or Toshiba with only warning messages shown during setup. Storage pools, RAID arrays, and DSM installation all proceed without functional restrictions, making it a flexible platform for users with existing drives or cost-sensitive deployments.

Storage Feature	Synology DS1522+	Synology DS1525+
Drive Bays	5 × 3.5″/2.5″ SATA HDD/SSD (Hot-swappable)	5 × 3.5″/2.5″ SATA HDD/SSD (Hot-swappable)
M.2 NVMe Slots	2 × M.2 2280 (Cache only, 3rd-party SSDs allowed)	2 × M.2 2280 (Cache & Storage Pool, Synology SSDs only)
Maximum Drive Bays (with Expansion)	15 (with 2 × DX517 via eSATA)	15 (with 2 × DX525 via USB-C)
Supported RAID Types	SHR, Basic, JBOD, RAID 0/1/5/6/10	SHR, Basic, JBOD, RAID 0/1/5/6/10
Max Internal Volumes	64	32
Max Volume Size	108 TB	200 TB (requires 32 GB RAM)
NVMe Storage Pool Support	Not supported	Supported (Synology SNV drives only)
3rd-Party Drive Support	Fully supported (with warnings)	Blocked (DSM install/expansion/recovery restricted)
RAID Recovery with Unverified Drives	Supported	Not allowed
Storage Pool Expansion (Unverified)	Supported	Blocked
Hot Spare Assignment (Unverified)	Supported	Blocked
Drive Migration (with 3rd-party drives)	Functional, with warnings	Allowed, but persistent warnings & blocked expansion

The DS1525+, by contrast, enforces the strict drive verification policy introduced in Synology’s newer Plus series models, like the DS925+ and DS1825+. At launch, only Synology-branded drives (HAT3300, HAT5300, SAT5200, and SNV3400 series) are listed as officially compatible. If users attempt to initialize DSM using unverified HDDs—such as a standard WD Red Plus or Seagate IronWolf—the installation process will be blocked entirely. This represents a significant limitation for long-time Synology users who are accustomed to broader hardware flexibility. Even after successful DSM setup, the system will not allow users to expand storage pools, rebuild degraded RAID arrays, or assign hot spares using non-verified drives. Persistent warnings and degraded status indicators in Storage Manager will appear even for migrated volumes, making the DS1525+ less accommodating for mixed-media configurations or DIY upgrades. SATA SSDs, while slightly more flexible in some scenarios, are still subject to similar warning behaviors post-install.

Further separating the two models is support for NVMe-based storage pools. The DS1522+ only allows M.2 NVMe SSDs to be used for read/write caching, and it permits the use of third-party SSDs for this function, giving users a cost-effective route to performance acceleration. The DS1525+, however, allows these NVMe slots to be used for full DSM storage volumes—but only when using Synology-verified SNV-series SSDs. This enables the creation of fast, low-latency storage pools using NVMe media, which is a compelling advantage for certain workflows (like media scratch disks or high-speed sync folders). Still, the restricted compatibility policy limits practical utility for those who already own quality NVMe drives from other vendors. In short, while the DS1525+ technically offers more advanced storage architecture, the DS1522+ offers far more freedom, especially for users managing legacy systems, migrating data from older Synology devices, or sourcing their own HDDs and SSDs independently.

Synology DS1525+ vs DS1522+ NAS Comparison – DSM Capabilities

Both the DS1525+ and DS1522+ run Synology’s DSM 7.2 operating system and provide access to the same broad library of official and third-party packages. This includes core applications such as Synology Drive for file sync and access, Synology Office for collaborative documents, and Active Backup for Business for system-wide backup management. The app experience is largely identical on both devices, with support for Virtual Machine Manager, Hyper Backup, Snapshot Replication, Synology Photos, and Surveillance Station. However, the differences in system hardware and compatibility enforcement subtly influence how DSM behaves and what features remain available under different configurations. For example, both models support up to 256 snapshots per shared folder and a system-wide maximum of 4,096 snapshots, but users on the DS1525+ will be subject to stricter compatibility enforcement in DSM’s Storage Manager if using drives that aren’t on Synology’s approved list.

DSM Feature / Capability	Synology DS1522+	Synology DS1525+
DSM Version	DSM 7.2+	DSM 7.2+
Max Internal Volumes	64	32 ▼
Max Single Volume Size	108 TB	200 TB (requires 32 GB RAM) ▲
Snapshot Replication	256 per shared folder / 4,096 total system snapshots	256 per shared folder / 4,096 total system snapshots
Synology Drive Users	Up to 60	Up to 80 ▲

Hybrid Share Folder Limit	10	10
Surveillance Station (H.265)	40 cameras / up to 1200 FPS	40 cameras / up to 1200 FPS
Maximum SMB Connections (RAM Expanded)	30	40 ▲
RAID Recovery with 3rd-Party Drives	Supported	Blocked
Storage Expansion with Unverified Drives	Supported	Blocked
Hot Spare (Unverified Drives)	Supported	Blocked
M.2 NVMe Caching (3rd-Party SSDs)	Supported	Blocked
NVMe Storage Pool Creation	Not supported	Supported (Synology SNV SSDs only)
DSM Storage Manager Behavior (Unverified)	Warnings only, all features functional	Persistent alerts, blocks expansions and rebuilds
High Availability Support	Yes	Yes
Full System Backup (Hyper Backup)	Yes (DSM 7.2+)	Yes (DSM 7.2+)

Where this becomes particularly relevant is during system migration or advanced storage scenarios. The DS1522+ handles drive migration and unverified HDDs without functional limitation. DSM will display minor warnings but still permit RAID recovery, storage pool expansion, hot spare assignments, and cache creation—even with mixed-brand hardware. By contrast, the DS1525+ introduces active blocks within DSM for unsupported drives. Users migrating from older Synology NAS devices using drives like WD Red Plus or Seagate IronWolf will find that, while the DS1525+ may import the pool, DSM will flag the drives as unverified and prevent future RAID rebuilds or expansions unless all disks are from Synology’s supported list. These alerts cannot be disabled, and they will persist across the user interface, making the system appear at risk even if the drives themselves are healthy. This creates a significant difference in administrative experience, especially for IT professionals managing multiple systems or resellers integrating legacy hardware.

In terms of user and service scalability, the DS1525+ supports slightly higher limits overall. It allows for up to 80 Synology Drive users and Office users (versus 60 each on the DS1522+) and can support up to 8 concurrent virtual machines versus 4 on the DS1522+, assuming sufficient RAM is installed. Surveillance Station camera and FPS limits are virtually identical, and both models support High Availability, Hybrid Share, SAN Manager, and central management features. However, the DS1525+ supports larger single volume sizes—up to 200 TB if upgraded to 32 GB RAM—compared to the DS1522+’s 108 TB ceiling. In return, the DS1522+ offers more internal volume flexibility with support for up to 64 volumes, double the DS1525+’s 32 volume limit. This trade-off reflects Synology’s shifting priorities in DSM: the DS1525+ favors fewer, denser volumes and more centralized control, while the DS1522+ gives power users finer-grained storage separation. Both systems excel with DSM, but your experience will differ depending on whether you prioritize scalability and structure—or open, hardware-flexible operation.

Synology DS1525+ vs DS1522+ NAS Comparison – Conclusion

The Synology DS1525+ and DS1522+ may look nearly identical on the outside, but they diverge sharply in philosophy, system behavior, and long-term value. The DS1522+, launched in 2022, stands as one of the last truly flexible 5-bay NAS systems in Synology’s portfolio. It offers a dual-core AMD Ryzen R1600 processor with excellent single-thread performance and supports up to 15 drives with two DX517 expansions. More importantly, it retains the traditional Synology approach to third-party drive compatibility—meaning users can install and operate a wide range of HDDs and SSDs (Seagate, WD, Toshiba, etc.) without system blocks. DSM will issue warnings if a drive isn’t officially listed, but critical features like RAID recovery, storage pool expansion, and hot spare assignment continue to function. That level of hardware openness makes the DS1522+ particularly attractive to power users, budget-conscious builders, and small IT teams looking to repurpose existing hardware. The DS1525+, released in 2025, represents a subtle but significant shift in Synology’s design strategy. On paper, it offers solid upgrades: a quad-core AMD Ryzen V1500B processor that enables better multitasking, faster 2.5GbE LAN ports for improved data throughput, lower noise and power consumption, and full NVMe storage pool support (with Synology SSDs). These improvements make the DS1525+ a better fit for users running multiple simultaneous services—such as Surveillance Station, Synology Drive, and Docker containers—all while maintaining smooth operation. However, these benefits come with stricter limitations. The unit enforces Synology’s 2025-era drive verification policy, which outright blocks DSM installation or RAID operations with unverified drives. Migration is allowed, but users will be met with persistent warnings, degraded system status indicators, and feature restrictions that can’t be bypassed. The flexibility to reuse older drives, expand arrays freely, or mix hardware brands has been systematically curtailed.

In essence, the choice between these two NAS systems reflects more than just performance—it’s a decision between openness and control. The DS1522+ remains a strong all-rounder for users who want to build their system on their own terms, manage diverse storage needs, or repurpose hardware they already trust. It’s well-suited to small businesses, creators, and experienced users who value transparency and adaptability. The DS1525+, by comparison, is more refined, but also more prescriptive. It favors users willing to commit fully to Synology’s ecosystem—those who prioritize simplicity, tighter integration, and long-term consistency, even at the expense of flexibility. It’s a better fit for turnkey environments where reliability and vendor support matter more than customization. Both NAS devices are excellent in their own right, but the right choice depends entirely on how much control you’re willing to trade for convenience—and whether your NAS should be a platform you shape, or a solution that shapes your workflow.

Synology vient d’officialiser leDS425+, le successeur du DS423+. Cette nouvelle itération s’inscrit dans la stratégie de renouvellement de la gamme DSx25+, marquée par l’introduction tant attendue du 2,5 Gb/s. Cependant, au-delà de cette amélioration réseau, les évolutions restent modestes. Ce nouveau venu justifie-t-il réellement un investissement ?

Synology DS425+ vs DS423+

Processeur : Même Combat

Les 2 NAS partagent rigoureusement la même architecture. C’est le processeur Quad-Core Intel Celeron J4125 cadencé à 2,0 GHz (boost à 2,7 GHz) qui équipe aussi bien le DS425+ que le DS423+. Ce choix peut surprendre dans un contexte où la concurrence mise sur des puces plus récentes.

Ce processeur J4125 date un peu, mais il a fait ses preuves. Il présente aussi l’avantage d’intégrer un iGPU (processeur graphique) Intel UHD Graphics 600, une caractéristique importante pour les utilisateurs souhaitant faire du transcodage vidéo matériel avec Plex ou Jellyfin… ce qui n’est pas possible avec les processeurs AMD Ryzen Embedded des autres modèles DSx25+

Mémoire : Configuration inchangée

Du côté de la mémoire vive, la configuration demeure strictement identique. Chaque modèle embarque 2 Go de RAM DDR4 non-ECC soudée sur la carte mère, avec un slot d’extension permettant d’atteindre un maximum de 6 Go. Si cela reste suffisant pour les usages classiques, cette configuration peut rapidement montrer ses limites dans des scénarios plus exigeants : machines virtuelles, conteneurs Docker, nombreux flux de vidéosurveillance simultanés, etc.

Connectique

La principale nouveauté du DS425+ réside dans sa connectique réseau modernisée. Là où le DS423+ propose 2 ports RJ45 1 Gb/s, le DS425+ introduit un port 2,5 Gb/s accompagné d’un autre port 1 Gb/s.

Cette évolution, longtemps réclamée par la communauté, permet enfin d’exploiter pleinement les switchs 2,5 Gb/s ou supérieur qui se démocratisent dans tous les foyers. Pour les transferts de gros volumes ou la synchronisation Cloud, cette amélioration se traduit par des gains de temps substantiels, particulièrement appréciables dans les environnements multi-utilisateurs.

Politique de compatibilité plus stricte

À ce jour, seuls les disques Synology sont officiellement compatibles avec la série DSx25+, une politique qui risque d’alourdir le coût total de possession. Cette approche s’aligne sur celle observée précédemment, suggérant une stratégie globale de contrôle de l’écosystème.

Tableau comparatif DS425+ vs DS423+

Faut-il passer au DS425+ ?

Le Synology DS425+ s’inscrit davantage dans une logique de rafraîchissement que d’une véritable révolution technologique. L’ajout du port 2,5 Gb/s constitue indéniablement l’amélioration la plus significative, répondant enfin aux attentes des utilisateurs équipés d’infrastructures réseau modernes.

Si vous possédez déjà un DS423+, la migration ne se justifie que dans des scénarios très spécifiques (besoin absolu de débits réseau supérieurs). Pour les nouveaux acquéreurs, le choix dépendra essentiellement de leur approche vis-à-vis de la politique de disques certifiés.

Synology Explain WHY They Changed Drive Support and Verification in 2025 NAS

During a recent visit to Taipei for Computex 2025, I took the opportunity to visit Synology’s headquarters and speak directly with company representatives about one of the most discussed and divisive topics in the NAS community today — the company’s increasingly strict stance on hard drive compatibility. With the rollout of Synology’s latest generation of hardware, users have been met with significant limitations on the use of third-party drives, prompting concern over reduced flexibility, potential e-waste, and the future direction of Synology’s hardware ecosystem. This article provides a can overview of that visit, beginning with the HQ tour, but mainly it is about putting several big questions users have about the brand’s change in support of Seagate, WD, etc on their 2025 devices.

Four core questions — based on direct community feedback — were put forward, addressing the motivation, risks, and future implications of Synology’s current drive support policy. Each answer is presented exactly as delivered. Note, this article is not sponsored by Synology and they have no control over the editorial stance and output! For users, partners, and industry observers alike, understanding these policy shifts is essential for making informed decisions about Synology systems moving forward.

Touring the Synology Headquarters

The Synology headquarters tour took place during a coordinated visit arranged alongside the Computex 2025 trade event. Approximately 30 to 40 individuals were in attendance, a mix that included official Synology partners, resellers, independent media, and technology commentators. The tour began with a structured company overview presentation outlining Synology’s operational history, business units, and market positioning.

While much of this information was familiar to long-term observers, it served to reinforce the company providing integrated storage and data management solutions. The presentation also included a brief overview of Synology’s global distribution and the evolving structure of its enterprise product lines.

Attendees were then guided through various areas of the facility, which covered several floors within a shared building. Synology does not occupy the entire structure, but the portions shown during the tour were substantial, comprising office sections, collaborative workspaces, logistics coordination areas, and support-related operations. Notably, many desks were temporarily unoccupied due to staff presence at Computex’s Nangang Exhibition Center.

Nonetheless, the offices remained populated with active terminals and systems undergoing live testing.

A significant portion of the tour focused on the environmental and durability testing facilities, including designated zones for acoustic profiling, thermal analysis, and dust resilience. The diversity of units being tested suggested coverage across multiple device classes, including both rackmount and desktop models.

The most extensive portion of the tour was the dedicated test and burn-in area. This floor was almost entirely devoted to long-term performance and diagnostic evaluations. Numerous Synology NAS units — some dating back to the early 2010s — were in continuous operation, either running synthetic workloads or undergoing compatibility assessments with the current DSM operating system.

The presence of so many legacy devices in active testing underscored the company’s emphasis on software longevity and cross-generational hardware support. However, it also provided a contrast to Synology’s new strict verification policies, especially given the mixed hardware environments visible during testing. The tour was led by ZP Kao, Sales Director at Synology, and Chad Chiang, Regional Manager for the UK and Germany, who offered clarification and responded to several direct inquiries during the walkthrough.

Why Has Synology Changed Its HDD Support Policy? Questions and Answers

Questions I put to Synology about their change in policy regarding verifying and supporting drive media being used on their 2025 and later series of NAS devices. I based these on the comments and suggestions from videos on the YouTube channel and comments on previous articles. I am under no illusions that these changes by Synology in their drive support policies have financial justifications (ranging from Support efficiency and it’s financial overhead, to the simple profitability of prioritizing their own labelled firmware optimized storage media choices over those of other brands), but I wanted to know if these were the only reasons for this? What other reasons could Synology provide to support this large and unpopular move. Thank you once again to Chad Chiang for taking the time to answer these questions.

Note – for a better understanding of the current DSM Support of Unverified media, as well as test scenarios detailing each setup and how DSM handles it, you can read it HERE in my Test Article.

How has the verification process changed for which drives you can use on Synology systems moving forward? And are there drive options from WD and Seagate currently undergoing support verification?

Answer – At Synology, we constantly reflect on a core question: Why do people choose a NAS? We believe the answer lies in the need for secure, reliable, and hassle-free data storage. This belief has guided our mission for over a decade. When analyzing our support history, the data clearly shows that systems using Synology-branded drives experience 40% fewer issues compared to those with third-party HDDs. This insight underscores the importance of using thoroughly tested drives. As for which third-party vendors are currently undergoing drive verification, we’re unable to disclose details. For the most accurate and up-to-date information, we recommend reaching out directly to the respective manufacturers.

The response positions Synology’s verification changes as a reliability-focused initiative and smooth platform running as the chief reasoning for them, referencing internal data that suggests a 40% reduction in support issues when Synology-branded drives are used. However, as mentioned previously, the statement does not provide supporting metrics such as sample size, timeframes, or specific failure modes, making it difficult to assess the scope or significance of this claim. I do not doubt that it is true, but without the X/Y and details of how this result was achieved, we are only getting half the story here.  The policy shift is framed as a precautionary measure aimed at minimizing user disruption, but the absence of transparency regarding ongoing verifications with WD or Seagate limits clarity for users seeking alternatives – which is why users are seeing this more as a means for the brand to increase profitability in the 2025 series as a bundled utility purchase – not as a means of system stability.

Ultimately, discussing the technical standards or benchmarks involved in the verification process in paramount here. It largely confirms that responsibility for future third-party compatibility lies with the drive manufacturers themselves, effectively shifting the onus of transparency to them. While it is understandable that Synology might want to mitigate support complexity, the lack of specificity about how the verification criteria have evolved or what steps vendors must follow leaves key questions unanswered for both users and third-party storage providers. I reached out to representatives from Seagate and WD to see if they could elaborate further on this new media side verification process with their respective NAS/Server class media – neither was able to provide further details at this time.

Users are able to migrate existing storage arrays that feature Unverified/unsupported drive media in previous Synology systems into 2025 Plus series devices and still use DSM services – however once they do so, they are unable to use the same model ID of drives to perform RAID recovery, RAID expansion or introduced a hot spare, unless that drive is on the verified drive list. Why is this?

Answer- Advanced operations such as RAID recovery, expansion, or hot spare assignment are technically intensive and carry a higher risk of data loss if inconsistencies arise. Drives that haven’t been validated through Synology’s verification process may behave unpredictably under stress, impacting array stability or performance. For this reason, support for these functions is limited to verified drives—a precaution designed to safeguard user data and maintain long-term system reliability.

So, this answer outlines Synology’s rationale for restricting critical RAID operations on unverified drives and It emphasizes the increased risk associated with advanced storage operations, particularly when performed on drives that may not have been tested under stress or fault conditions. The justification focuses on data integrity and system reliability, suggesting that verified drives have undergone stress testing scenarios that others have not. However, the lack of granularity in what defines “unpredictable behavior” makes it difficult to independently evaluate the severity or frequency of these issues. Much like the statistics point earlier, this seems a remarkable stretch in terms of reaction to what many users would consider a very, very low % risk factor. Equally, though there is an argument that some drive media is less suitable for NAS usage (eg the WD Red SMR drives, desktop single drive use media like Seagate Barracuda and high power draw HDDs/SSDs in some cases), these make up a very small % of drive media in the market and using this as a reasoning to effectively bar the continued support of drive media that has been supported/used in Synology server use over the last 2 decades to prevent RAID recovery and Expansion in the latest gen for those carrying them over seems insane overkill.

The policy effectively limits upgradability and flexibility in mixed-drive environments. While it is technically reasonable to restrict risky operations on unvalidated components, the ability to migrate but not expand or rebuild a RAID introduces a half-measure — allowing users to enter unsupported configurations while restricting them mid-cycle. The result is a system state that may appear functional at first but ultimately lacks key functionality unless users conform to the verified list. For long-term users upgrading from older systems, this shift can lead to unexpected limitations without adequate warning, particularly in small or home office deployments. The messaging has been poor and though I made a video about these limitations (embedded above), there is practically no other clear and transparent information about this online (with incongruous detailson the Synology Knowledge base that could stand to be a lot clearer and louder).

HOT TAKE, and hear me out – If Synology do not allow support of RAID repair/Expansion on drives that have been migrated over from older NAS systems where the drives WERE originally supported (unless they use 2025 verified drives) because of reasons of stability, I have a somewhat extreme suggestion. As unpopular as it might have been, Synology should have just BARRED the support of migration from older generation Synology NAS devices with unverified drives entirely. I personally think they should have allowed for RAID repair/Expansion of unverified drives, but if they are going to pursue this for reasons of system stability, they should have committed to this fully and not allowed this grey area with migration. As it just looks bad for the brand, as means of ensuring people can upgrade/remain in the ecosystem, but then have limited scalability when those older drives require replacement/growth.

Were pre-populated Synology NAS devices considered, given the strict verified support stance that this new Synology hardware generation contains?

Answer – Regarding pre-populated NAS solutions, there hasn’t been significant internal discussion or a formal strategy around this model. As such, I don’t have a concrete answer at this time. The focus remains on ensuring that any storage media used—whether user-installed or bundled—is fully verified to meet Synology’s reliability standards.

Not much to unpack here. It makes sense. I imagine they DID discuss this as an option (as they are already engaging with this with systems like the Beestation), but at least for now, it seems off the table. As unpopular as this might have been, in some ways it could have solved a lot of this friction for some users. Provide the 2025 PLUS series as an empty/enclosure-only solution with similar compatibility as the 2024 and earlier generation – but then also supply several pre-populated options that feature Synology drive media as standard. However, that would be a different discussion entirely (eg logistics, SKUs, viability, ROI by offering this alongside flexible options).

Can you provide example(s) of critical system issues that using unverified drives caused, that were the tipping point for this new strict HDD support policy?

Examples of what stepped up our verification process moving forward:

Performance Issues: Unverified drives may function under light workloads but can suffer serious performance drops (e.g., IOPS decline) under multi-user access or when running demanding services like virtualization, backup, or databases. This can lead to poor user experience or service disruptions (e.g., iSCSI timeouts).

Stability Risks: Without thorough testing, unverified drives are more prone to failures under stress conditions such as unexpected power loss or long-duration file transfers—leading to timeouts, reboot failures, or data integrity issues in high-load or long-term operations.

Compatibility Problems: Drives not validated for compatibility may show unstable behavior with certain NAS controllers, resulting in drive drops, RAID instability, or data access interruptions over time.

Advanced Feature Failures: Unverified drives may fail during operations like SMART testing or Secure Erase, especially after unexpected power outages. Some drives may not respond properly under frequent access or specific command sets, affecting system stability.

Drive Failures Under High Load or Density: Some drives may become unresponsive under high data density or I/O intensity, with issues persisting even after a reset.

The examples provided by Synology highlight a variety of operational issues associated with unverified drives, most of which relate to performance degradation, system instability, or failure of advanced features under stress. These scenarios focus on workloads involving sustained I/O, power fluctuations, and controller-level interactions. In isolation, many of the issues described are plausible for lower-tier or unsuitable drive models, particularly in demanding or enterprise-like environments. That said, that are very low margins (eg 0.01% or lower) when you look at the traditional deployment of many Synology NAS solution in the Plus series. Again though, the scale and frequency of these issues remain unclear. There is no indication of how widespread such failures are across Synology’s user base, nor whether they represent rare edge cases or common occurrences. The examples also apply more logically to enterprise or high-density configurations, whereas the same strict policies now affect all tiers — including two-bay and four-bay systems used by home and prosumer users. Without concrete statistics or clearer thresholds, it is difficult to assess whether these issues justify the breadth of the policy. The policy appears to target potential worst-case scenarios, but may have broader consequences for user flexibility than the risk profile necessarily warrants.

Additional Information and Details from the MyBroadband Article

Further context on Synology’s new drive compatibility policy was provided in an interview between MyBroadband journalist Daniel Puchert (click to read) and Michael Chang, Synology’s Regional Sales Manager. The discussion reinforced many of the points raised during the HQ visit, while also offering additional information into the motivations behind Synology’s stricter approach to drive support in their latest generation of NAS systems. Chang explained that Synology’s primary objective was to ensure product reliability and reduce system-level faults that were increasingly traced back to third-party hard drives. According to Chang, complaints received by Synology often involved third-party drive issues, yet Synology would still be held accountable by users due to their role as the NAS provider. This prompted the company to centralize responsibility and tighten control over supported hardware configurations. While Synology-branded drives are currently the only models certified, Chang noted that other vendors are being invited to participate in the compatibility validation program — provided they meet the same testing standards.

(In the case of the NAS drives) “..because Synology’s product would typically facilitate the usage of third-party hard drives, it would also be the scapegoat for any faults with the entire system.”

“..complaints received by Synology regarding issues relating to its NAS devices were most often caused by faulty hard drives.

“severe storage anomalies have decreased by up to 88%” for hard drive models that have adopted its hard drive compatibility policy, compared to older models.”

“We still welcome third parties to join Synology’s ecosystem and have invited vendors to join our validation program,”

Michael Chang, Synology Regional Sales Manager – full article HERE

The article also mentioned that Synology-certified drives undergo over 7,000 hours of testing, and systems using those drives reportedly experience 40% fewer failures than those using uncertified media. Additionally, Synology claims that severe storage anomalies have dropped by up to 88% in systems following its compatibility policy. Although Chang confirmed that third-party compatibility may expand in the future, it will only do so under strict adherence to Synology’s internal benchmarks. These statements align with Synology’s position during the HQ tour, further emphasizing a shift toward a closed, highly controlled ecosystem that prioritizes consistent performance over hardware flexibility.

Synology and HDD Support and Verification – Conclusion and the Long Term

My biggest issue with all this is that, almost certainly, we are going to see Seagate, WD, Toshiba and more slow (slooooooooowly) appear on the compatibility lists for a number of the 2025 generation of devices over the coming months. So, what was all this for? The PR damage and likely early sales damage of the Synolgoy 2025 Series because of this change of support I would estimate is going to be pretty substantial – and all the reports and reactions to this online are not going to go away as soon as a Seagate Ironwolf or WD Red drive appears on the support lists. Also, Synology work on these devices for a very, very long time before launch – why is all this happening now – and not before launch. The cynic in me wants to just assume it was pure profitability and that Synology want to maximize profits, and if when this does begin to U-Trun ,that the brand can say that it was the plan all along. But whether that is true or not, the damage to the brand in the eyes of a substantial % of their long term fans is notable, and with many more players in the market (UniFi, QNAP, UGREEN and more) launching new products in Q3 and Q4 – is this all going to be a gamble by the brand that ends up costing them more than just leaving the support status quo where it was? Only time will tell.

Dans ce tutoriel, nous allons installer LanguageTool sur un NAS Synology avec un conteneur Docker, afin de bénéficier d'un correcteur de fautes self-hosted.

The post Comment installer LanguageTool sur un NAS Synology ? first appeared on IT-Connect.

Lors du Computex 2025 à Taipei, plusieurs annonces importantes ont été faites dans l’univers des NAS avec  Synology, QNAP et ASUSTOR. Ces 3 fabricants taiwanais ont présenté des solutions allant du NAS domestique aux serveurs de stockage pour les entreprises avec des avancées sur les performances et l’intégration de l’intelligence artificielle.

Synology : Stockage NVMe enterprise et la nouvelle Série DS+

PAS7700 : Un PAS décisif vers le stockage Flash Enterprise

Synology passe à la vitesse supérieure avec le lancement de sa gamme Parallel Active Station (PAS), inaugurée par le modèle PAS7700. Ce système 4U en cluster dual-node, entièrement NVMe, marque un tournant dans la stratégie de la marque vers les solutions de stockage hautes performances pour l’entreprise.

Le PAS7700 affiche des performances impressionnantes annoncées : jusqu’à 2 millions d’IOPS en lecture aléatoire 4K et 30 Go/s en lecture séquentielle 64 KB. Chaque nœud embarque 24 emplacements pour les nouveaux SSD U.3 NVMe conçus en interne par Synology, une première pour le constructeur. L’unité peut être étendue via le PAX224, pour atteindre jusqu’à 8 Po de capacité logique, grâce à une technologie de réduction de données intégrée affichant un ratio moyen de 5:1.

Renouvellement de la série DS+ avec du 2,5 GbE

Synology a également dévoilé 6 nouveaux modèles de sa série DSx25+, incluant les DS225+, DS425+, DS725+, DS925+, DS1525+ et DS1825+. La principale nouveauté réside dans l’arrivé du port réseau 2,5 Gb/s sur l’ensemble de la gamme, répondant enfin aux attentes des utilisateurs.

À noter qu’il se murmure que Synology sortirait ses propres switchs (estampillés Synology) d’ici la fin de l’année.

Politique controversée des disques certifiés

Une décision qui fait débat concerne la nouvelle politique de Synology imposant l’utilisation de disques testés et validés par ses soins. Ivan Lebowski, Sales Team Leader France et Afrique de Synology, justifie cette approche : « nous voyons trop d’utilisateurs venir vers nous parce qu’ils rencontrent des problèmes avec des disques pour lesquels nous ne pouvons pas leur apporter de support ».

QNAP : innovation autour de l’IA et du stockage évolutif

QuTS Mega et stockage à l’échelle du PétaOctet

QNAP a impressionné avec QuTS Mega, son système d’exploitation NAS évolutif (scale-out) conçu pour les déploiements haute capacité. Cette architecture permet à plusieurs nœuds NAS de fonctionner dans un environnement clusterisé unique, supportant une mise à l’échelle linéaire de la capacité et des performances.

Le système supporte jusqu’à 96 nœuds avec une capacité totale utilisable pouvant atteindre 45 PétaOctets. QNAP a démontré cette technologie avec un boîtier JBOD de 60 baies compatibles SAS ou SATA, offrant un débit de 12 Gb/s par lien.

Solutions IA et connectivité Thunderbolt 5

On continue avec le TVS-AIh1688ATX. Il s’agit d’un NAS équipé d’un Intel Core Ultra (24 cœurs) accompagné d’unités de traitement neuronal (NPU 13 TOPS). Il est compatible Thunderbolt 5 (en option) destiné aux workflows de travail à destination des créatifs. Ce QNAP dispose de 2 ports USB 4 (par défaut) et 2 ports réseau 10 Gb/s.

QNAP a fait plusieurs démonstrations de la prochaine version de QSirch basée sur l’IA pour retrouver facilement des documents, pouvant également lire le contenu de ces derniers… tout en respectant la confidentialité. En effet, l’IA fonctionne en local et n’a pas besoin d’accès extérieur pour fonctionner.

Nouveaux modèles d’entrée de gamme

Les TS-262A et TS-462A renouvellent l’entrée de gamme avec un processeur Intel N5095 à 2,2 GHz (boost jusqu’à 2,9GHz), avec jusqu’à 16 Go de RAM DDR4 et avec 2 emplacements M.2 NVMe. On notera la présence de 2 ports USB 2.0, 2 ports USB 3.2 Gen 2, ainsi qu’un port 2,5 Gb/s. Ces modèles abandonnent le port HDMI et l’emplacement PCIe présents sur la génération précédente.

ASUSTOR : évolutions mesurées, mais ciblées

Lockerstor Gen2+ : Amélioration de la connectivité

Au Computex 2025, ASUSTOR a dévoilé des mises à jour ciblées de ses NAS, à commencer par le Lockerstor 6 Gen2+ (AS6706T). Ce modèle voit sa connectivité évoluer avec le remplacement des ports 2,5 GbE (rouges) par des ports 5 GbE (bleus), offrant une bande passante doublée tout en restant rétrocompatible avec les réseaux existants.

Solutions rackables professionnelles

Côté entreprises, ASUSTOR renforce sa présence sur le segment professionnel avec les Lockerstor 12R Pro Gen2, déclinés en formats 3U et 4U. Ces NAS rackables embarquent des processeurs AMD Ryzen 7 Pro, 16 Go de mémoire DDR5 ECC et 2 ports réseau 10 Gb/s, visant les infrastructures virtualisées ou les besoins en stockage à haute disponibilité.

En synthèse

Le Computex 2025 confirme la transformation du marché du NAS vers des solutions plus performantes et spécialisées. Synology mise sur le stockage flash enterprise et l’écosystème fermé, QNAP pousse l’innovation vers l’IA et le stockage évolutif, tandis qu’ASUSTOR se concentre sur l’amélioration ciblée de ses produits existants. Ces évolutions répondent aux besoins croissants en performances et en capacité des utilisateurs professionnels, tout en soulevant des questions sur l’ouverture des écosystèmes et la compatibilité des composants tiers.

Synology vs QNAP NAS – Which Should You Buy in 2025?

When choosing a NAS solution in 2025, two brands dominate the conversation: Synology and QNAP. These Taiwan-based companies have evolved their offerings significantly over the years, adapting to changing user needs in backup, multimedia, virtualization, and enterprise storage. Synology, with a strong emphasis on software polish and ecosystem integration, continues to appeal to users who prioritize stability and consistency. QNAP, by contrast, leans into offering higher-spec hardware, customization, and flexibility, targeting tech-savvy users who want granular control over their system. This article explores how the two compare across hardware, storage capabilities, software platforms, security, pricing, and overall value. Both Synology and QNAP share a lot of baseline features: multi-platform support across Windows, Mac, and Linux; mobile apps for Android and iOS; web-based GUIs; encryption; multi-user access; and strong community ecosystems. Yet important distinctions emerge as you look deeper. These differences often boil down to Synology delivering a more consistent, “appliance-like” experience, while QNAP offers broader hardware choices and wider compatibility. Neither brand is universally better, but each fits different user priorities. Let’s break down how Synology and QNAP stack up in detail for 2025.

Synology vs QNAP NAS – Hardware Comparison

In terms of hardware variety and specification, QNAP clearly maintains an advantage in 2025. QNAP offers a wider range of NAS models across every price tier, providing more options for users looking for features like 2.5GbE or 10GbE ports, Thunderbolt connectivity, PCIe expandability, and support for AI or GPU cards. Many QNAP systems at even mid-tier levels offer multi-core CPUs, 2.5GbE as a minimum, and M.2 NVMe slots for caching or storage pools. Synology, while offering a hardware range from ARM-based entry units to Xeon-powered enterprise models, typically emphasizes efficiency and stability over raw horsepower, often shipping systems with lower-core-count processors and 1GbE networking by default.

However, Synology’s hardware strategy is tightly coupled to its software-first philosophy. Devices are designed to maximize compatibility, power efficiency, and seamless operation with DSM. Some newer 2025 Synology models do offer improvements — such as M.2 NVMe storage pools and optional 10GbE upgrades — but their pace remains slower compared to QNAP’s frequent hardware refresh cycles. For users whose priority is high performance, customization, or bleeding-edge hardware, QNAP offers far more compelling options. For those seeking low-power, quiet, turnkey systems, Synology still provides highly reliable appliances.

Synology vs QNAP NAS – Storage Services and Scalability 

Storage capabilities represent a growing area of divergence. Synology’s storage ecosystem emphasizes stability and data integrity through Btrfs file systems, SHR (Synology Hybrid RAID), fast RAID rebuilds, and snapshot technology. However, Synology has dramatically tightened its drive compatibility rules from 2025 onwards, particularly in the Plus series and higher, limiting users to certified Synology drives for initialization. This hardline approach restricts flexibility, as users cannot freely install third-party HDDs or SSDs. Meanwhile, users still benefit from technologies like SHR, making mixed-drive RAID arrays easier to manage, though concerns remain about SHR’s future viability under Synology’s evolving drive policies.

	SERVICE	SYNOLOGY	QNAP	Notes

	ZFS Support	(DSM 7.2+ select models)	(QuTS hero)	Synology uses Btrfs more widely
	Storage Pools			Pool-based management
	Thin Provisioning			On supported file systems
	Storage Snapshots	(Btrfs-based)	(ZFS/ext4-based)	Both support snapshot schedules
	Inline Deduplication	(Btrfs)	(ZFS)	Both support dedup, method differs
	SSD Cache (Read/Write)			Model-dependent

	Active Backup for Business			Enterprise-grade backup (free)
	Snapshot Replication			Data versioning support
	Cloud Sync			Multi-cloud sync integration

QNAP’s storage flexibility is far greater. Users can utilize almost any NAS-rated or server-class drive from vendors like Seagate, Toshiba, and WD, without vendor lock-in. Beyond standard RAID levels, QNAP offers Qtier for intelligent auto-tiering between SSDs and HDDs and supports ZFS through its QuTS hero operating system. ZFS integration introduces enterprise-grade features such as inline deduplication, compression, triple-parity RAID options, and even faster rebuilds. Expansion is another strong suit for QNAP, with broad support for external expansion enclosures over USB and PCIe, while Synology supports far fewer expansion units. In short, QNAP offers a more powerful, flexible storage environment but demands more technical knowledge to manage effectively.

Synology DSM vs QNAP QTS/QuTS  – Software Compared

Synology’s DSM (DiskStation Manager) remains the benchmark for NAS operating systems in terms of polish, consistency, and ease of use. Its streamlined UI, consistent app design, and stable system management tools make it highly user-friendly. DSM’s integration with Synology Drive, Hyper Backup, Active Backup for Business, and its Office suite provide turnkey productivity and backup solutions. However, Synology is moving increasingly toward a closed ecosystem, prioritizing first-party apps and services over broader third-party integration. Applications like Surveillance Station remain best-in-class, but recent trends — such as discontinuing Video Station — indicate Synology’s increasing control over its ecosystem.

Category	Feature	Synology	QNAP	Notes
Core OS	OS	DSM (DiskStation Manager)	QTS / QuTS hero	QuTS hero is ZFS-based
	Web GUI Dashboard			Both have polished interfaces
	Mobile Apps			DS apps (Synology), Qfile/Qmanager (QNAP)

	Notes / Tasks / Calendar			Productivity tools
	Mail Server & Chat			Business collaboration tools
App Ecosystem	App Center			QNAP has a broader variety
	Package Manager CLI	(synopkg)	(qpkg)	Command-line support for installs

QNAP’s QTS and QuTS hero systems offer greater flexibility and third-party support at the cost of consistency. Users can deploy a much wider range of apps, including those for AI recognition, media streaming, and backup tasks, often with deeper customization options. QNAP’s app ecosystem embraces both QNAP-native and third-party applications, with tools like HybridMount and Hybrid Backup Sync offering robust cloud and backup integrations.

However, design inconsistencies and a more complex setup process make QNAP platforms better suited to technically proficient users. QNAP systems offer more functionality out of the box but can feel less cohesive than Synology’s more curated environment.

Synology vs QNAP NAS – Security 

Synology continues to lead in NAS security in 2025. The company’s multi-layered approach — including an in-house Security Response Team, bug bounty programs, pen-testing partnerships, and rapid patching policies — maintains its reputation as one of the most secure NAS ecosystems. Security Advisor, SSL certificate management, encrypted folders, and proactive system audits are standard across DSM systems. Remote access via QuickConnect is tightly controlled to minimize exposure. This emphasis on hardening and responding quickly to vulnerabilities makes Synology a strong choice for users prioritizing security with minimal manual intervention.

	Service	Synology	QNAP	Notes
Security & Access	2FA (Two-Factor Authentication)			User-level protection
	VPN Server (OpenVPN, L2TP, PPTP)			Standard features
	Firewall + IP Blocking			Security policy management
	SSL Certificate Management			Let’s Encrypt, custom certs
	Security Advisor			Built-in vulnerability scanner

QNAP has made substantial strides in recent years to bolster its security posture, responding to earlier criticisms following ransomware incidents. The introduction of its own PSIRT team, participation in Pwn2Own, and improvements to myQNAPcloud services represent real progress. However, QNAP’s security tools, like Security Counselor, often need to be manually installed and configured. While they now offer multi-factor authentication and SSL options, the user experience around setting up and maintaining a secure environment still lags slightly behind Synology. Power users comfortable with managing network-level protections can achieve strong security on QNAP, but casual users may find Synology’s default setup safer out of the box.

Synology vs QNAP NAS – Price Point and Value 

QNAP consistently offers better raw hardware value for the price across its product range. A mid-tier QNAP NAS typically features higher-core CPUs, 2.5GbE or 10GbE networking, and expandability features like PCIe slots and multiple M.2 NVMe slots — features that, with Synology, are only available at much higher price points.

Additionally, QNAP’s lack of strict HDD compatibility listing (as currently the case for the Synology 2025 series, at the time of writing) and broader compatibility with storage and memory components can significantly reduce the total cost of ownership for DIY-minded users. Synology’s pricing, while generally higher, reflects its software development investment and the overall polish of its systems.

Buyers are paying for a more turnkey experience, better documentation, and consistent performance across the board. Moreover, Synology’s inclusion of powerful free tools like Active Backup for Business and Synology Drive adds enterprise-grade features without additional licensing costs, which in some cases offsets the hardware premium. Nonetheless, for users whose priority is maximum hardware performance and component freedom, QNAP usually offers a stronger return on investment.

Synology vs QNAP NAS – Conclusion and Verdict 

Choosing between Synology and QNAP in 2025 depends largely on user priorities. Synology remains the best choice for users seeking a polished, consistent, stable, and secure NAS experience. Its streamlined DSM platform, reliable first-party apps, and strong support infrastructure make it ideal for small businesses, prosumers, and general users who want a “set it and forget it” solution. However, Synology’s movement toward hardware and software lock-in may be off-putting to users who value flexibility or those unwilling to buy only Synology-branded components. QNAP, by contrast, excels in offering more powerful hardware, greater configuration freedom, and broader third-party app support. Users who want to customize, expand, virtualize, and maximize their system’s capabilities — and who are comfortable managing more complex setups — will find QNAP to be the more empowering platform. While its software consistency and security history lag slightly behind Synology, the gap has narrowed considerably. Ultimately, Synology is the stronger pick for users valuing simplicity and long-term stability, while QNAP offers more opportunities for those willing to trade simplicity for flexibility and raw performance.

Après le BeeDrive et BeeStation, Synology dévoile le BeeStation Plus, un boîtier de stockage réseau qui monte en gamme. Avec 8 To de stockage, un processeur Intel plus performant, 4 Go de RAM, cette nouvelle version a de quoi séduire. Mais est-ce suffisant pour justifier son prix ? Et surtout, à qui s’adresse vraiment ce produit ?

Retour sur la gamme BeeStation

Avant d’entrer dans le détail de cette version « Plus », rappelons rapidement ce qu’est BeeStation.

Synology est un acteur reconnu dans le monde du NAS depuis de nombreuses années. Son succès repose sur la fiabilité de ses produits et un écosystème logiciel robuste, basé sur DSM, une interface web riche en fonctionnalités : sauvegarde, partage, sécurité, streaming, collaboration, etc.

Mais l’univers du NAS reste trop souvent associé aux professionnels ou aux utilisateurs avancés. Pour élargir son public, Synology a lancé BeeStation : un NAS simplifié, prêt à l’emploi, avec un disque dur intégré et une interface allégée. Le but ? Proposer une solution de stockage cloud privé pour le grand public, sans les complexités d’un NAS traditionnel.

Synology ne mentionne jamais le terme « NAS » dans sa communication autour de BeeStation. L’objectif est clair : offrir une alternative simple aux solutions cloud comme Google Drive ou iCloud, sans les problèmes de confidentialité des données.

BeeStation Plus : une montée en gamme bien pensée

La BeeStation Plus reprend les bases du modèle précédent, mais les améliore significativement :

• Stockage intégré : 8 To en standard
• Processeur : Intel Celeron J4125 Quad-Core à 2,0 GHz (burst jusqu’à 2,7 GHz)
• Mémoire vive : 4 Go de RAM DDR4
• Connectique :
  • 1 port USB 3.0 Type-A
  • 1 port USB 3.0 Type-C
  • 1 port Ethernet RJ45 Gigabit (1 Gb/s)

L’autre nouveauté, c’est la prise en charge native de Plex, la célèbre application de streaming multimédia. De quoi transformer ce boîtier en serveur multimédia personnel, sans configuration complexe. Attention, afin de profiter pleinement de Plex et de l’accélération matérielle offerte par le BeeStation Plus, il faudra souscrire au Plex Pass.

Un produit simple, mais pas simpliste

Là où Synology continue de se démarquer, c’est dans sa gestion avancée des données, même sur un produit grand public. On retrouve des fonctionnalités rares chez la concurrence à ce niveau de gamme :

• Chiffrement AES-256 des données avant sauvegarde externe
• Sauvegarde centralisée de services cloud tiers (Google Drive, Dropbox, OneDrive, etc.)
• Accès distant sécurisé sans configuration réseau complexe

C’est ce genre de détails qui rend le produit intéressant pour des utilisateurs exigeants, sans les noyer dans des paramètres techniques.

Prix et disponibilité

La Synology BeeStation Plus (version 8 To) est disponible dès maintenant en commande, au prix public conseillé de 443,94 € TTC. Cela peut sembler un peu cher pour un produit aussi fermé, surtout comparé à un NAS classique, qui offre plus de flexibilité, d’évolutivité et souvent de meilleures performances.

BeeStation Plus semble être une solution idéale pour les utilisateurs à la recherche d’un stockage simple, prêt à l’emploi et sans configuration technique. Mais face à un NAS classique, le boiter apparaît comme une option trop fermée et peu évolutive, pour un prix assez important.

Synology (Finally) Reveals Managed PoE 10GbE Switches – The PS Series

At Computex 2025, Synology formally unveiled its new PS Series of PoE switches—marking the company’s first venture into dedicated network switching hardware. Designed specifically for surveillance environments, these switches are not meant to replace general-purpose managed switches, but rather to complement Synology’s Surveillance Station ecosystem. The lineup includes three models: the high-capacity PS2600+, the compact PS1000+, and the entry-level PS500. Each model is tailored for powering PoE cameras and streamlining IP surveillance setups, with features like centralized control through Surveillance Station and fanless operation. While this launch addresses a long-standing gap in Synology’s ecosystem, it is clear that these devices are intended for a niche surveillance role rather than enterprise-wide or enthusiast-grade switching solutions.

Why is a Synology Switch so Highly Demanded? And Why is This Not Quite What Everyone Wanted?

For years, users of Synology’s NAS and surveillance solutions have speculated about the company expanding into networking hardware, particularly switches. Given Synology’s existing ecosystem of NAS units, cameras, routers, and software like Surveillance Station and SRM, a managed PoE switch seemed like the logical next step to unify its offerings under a single, tightly integrated platform. Many envisioned a Synology switch that could serve not just surveillance but also general-purpose networking, VLAN management, and broader SMB/enterprise deployments—effectively competing with established names like Ubiquiti, Netgear, or QNAP.

However, the PS Series unveiled at Computex 2025 diverges from that expectation. The PS2600+ and PS1000+ are exclusively intended for use with Synology’s Surveillance Station, lacking broader Layer 3 management tools outside of this context. Meanwhile, the PS500 is a basic, unmanaged unit aimed more at simple deployments than network optimization. There are no bundled camera licenses, limited software extensibility, and no SRM integration. As a result, while these switches will likely appeal to users looking for a seamless Synology surveillance setup, they fall short of the more versatile, all-encompassing switch that many long-time Synology users were hoping for.

Synology PS2600+ 26 Port L2+ Managed PoE Switch

The PS2600+ is the flagship switch in Synology’s new lineup, featuring 24 PoE+ ports and 2 additional 10GbE SFP+ uplink ports. Designed for rackmount or desktop use, the PS2600+ is completely fanless, making it suitable for noise-sensitive environments. It delivers a total PoE power budget of 185W, allowing it to power multiple IP cameras, particularly in larger surveillance setups. It is fully managed and integrates directly with Synology’s Surveillance Station for centralized control, including power management, port diagnostics, and network topology mapping.

In terms of network performance, the PS2600+ offers a switching bandwidth of 88 Gbps and a forwarding rate of 65.47 Mpps. It supports Layer 2+ features, including inter-VLAN routing and DHCP server capabilities, allowing it to segment and route traffic in more complex surveillance deployments. However, its software integration is limited exclusively to Surveillance Station, and it lacks any compatibility with Synology’s SRM (Router OS) or general-purpose network management tools. It is best suited for installations where the switch, NAS, and cameras are all part of a single, unified Synology surveillance environment.

Synology PS500 5 Port Unmanaged PoE Switch

The PS500 is the most basic model in Synology’s PS Series and is designed primarily for entry-level surveillance setups. It offers a total of five ports, four of which support PoE+ for powering IP cameras or other devices. Unlike the other models, the PS500 is completely unmanaged—there is no software-based configuration, no VLAN support, and no integration with Surveillance Station CMS. It is intended for plug-and-play functionality, making it suitable for simple installations where centralized management is not required.

Despite its simplicity, the PS500 still delivers up to 60W of total PoE power and supports jumbo frames up to 9000 bytes. It is passively cooled and uses an external power supply, emphasizing its role as a compact, low-maintenance switch for desktop or wall-mounted deployments. While it doesn’t offer the flexibility or control of the PS2600+ or PS1000+, it fills a gap for users seeking a straightforward power delivery solution for small-scale IP camera installations.

Synology PS1000+ 10 Port L2+ Managed PoE Switch

The PS1000+ serves as the mid-range offering in Synology’s PS Series, targeting smaller surveillance deployments that still benefit from centralized management. It includes 8 PoE+ RJ45 ports and 2 standard 1GbE SFP ports for uplink or fiber connectivity. Like the PS2600+, this model is fanless and supports both rackmount and desktop installations. It offers a total PoE power budget of 65W, which is sufficient for a modest number of IP cameras or access points in home or SMB setups.

From a network performance standpoint, the PS1000+ provides 20 Gbps of switching bandwidth and a forwarding rate of 14.88 Mpps. It also supports VLANs, static routing, and DHCP services, and is managed entirely through Synology’s Surveillance Station interface. Its role is clearly focused—bridging NAS units and IP cameras under one platform, without offering broader Layer 3 functionality or third-party network integration. For users with Synology NAS-based NVR setups and fewer cameras, the PS1000+ provides a compact, low-noise, managed switch option.

Synology PS Series Switches, Conclusion and Verdict

Synology’s entry into the network switch market with the PS Series marks a significant, though narrowly focused, expansion of its surveillance ecosystem. These switches are clearly designed with Surveillance Station users in mind, offering streamlined power and network management for PoE camera deployments. While the PS2600+ and PS1000+ provide useful managed features for larger and mid-sized surveillance environments, and the PS500 delivers a simple plug-and-play option, none of these models address general networking needs outside of Synology’s surveillance scope. For those seeking a unified Synology environment for NVR deployments, these switches may be a welcome addition—but broader adoption will likely remain limited until Synology delivers more versatile, multi-role networking solutions.

Synology poursuit le renouvellement de sa gamme DSx25+ avec l’annonce du DS425+. Il s’agit d’un nouveau NAS 4 baies animé par un processeur Intel. Ce modèle vise les utilisateurs à la recherche d’une solution de stockage performante et compacte, tout en conservant le contrôle total sur leurs données…

Synology DS425+, un air de déjà-vu

Le DS425+ reprend une configuration bien connue des adeptes de la marque. Synology le décrit comme « un centre de stockage compact avec 100% de propriété des données ». Le DS425+ est un NAS 4 baies en façade, ainsi que2 emplacements pour des SSD NVMe accessibles par le dessous

Il est construit autour d’un processeur Quad Core Intel Celeron J4125 cadencé à 2 GHz (mode Burst jusqu’à 2,7) et 2 Go de RAM DDR4 (non ECC), extensible jusqu’à 6 Go.

Vous avez une impression de déjà-vu… c’est normal. Rien de révolutionnaire ici. Nous sommes sur la même configuration que le DS423+ (qui ressemblait déjà beaucoup au DS920+). La nouveauté se situe au niveau de la connectique…

Connectique : du mieux, mais peut mieux faire

La seule véritable évolution concerne la connectique réseau. Le DS425+ intègre enfin un port RJ45 2,5 Gb/s, en plus d’un port 1 Gb/s classique. Un ajout bienvenu, mais tardif par rapport à la concurrence qui propose du multi-Gig depuis plusieurs années.

On retrouve également 2 ports USB 3.0, dont un en façade.

Politique de compatibilité restrictive

Avec la série DSx25+, Synology renforce sa politique de compatibilité matérielle. L’installation de disques durs ou de SSD non officiellement validés peut entraîner l’apparition d’alertes, la désactivation du cache NVMe, voire l’impossibilité de créer un volume. En pratique, cela exclut de nombreuses références pourtant éprouvées, comme les Seagate IronWolf ou les WD Red, au profit exclusif des modèles Synology.

Présentée comme une mesure en faveur de la fiabilité, cette restriction limite considérablement la liberté de configuration des utilisateurs et peut engendrer un surcoût non négligeable. Si Synology souhaite maintenir la confiance de ses clients, une liste de compatibilité ouverte et transparente (incluant des marques tierces) devient urgente.

Prix et disponibilité

Le prix du DS425+ n’a pas encore été communiqué. On peut néanmoins s’attendre à un tarif proche de celui du DS423+ à son lancement, ce qui placerait ce nouveau NAS autour des 550€.

Malgré un positionnement intéressant, le DS425+ ne propose qu’un seul changement matériel par rapport à son prédécesseur, ce qui pourrait décevoir les utilisateurs à la recherche d’une réelle montée en gamme. On notera également la restriction croissante imposée par Synology quant à l’utilisation de disques durs et SSD tiers, un point à surveiller avant l’achat.

Synology Launches RS2825RP+ RackStation NAS for Business Deployments

As Synology continue its large-scale refresh of its solution portfolio, it is finally time to start talking about rackmount solutions! Although many were waiting on the RS1225+, it looks like the brand wants to ‘go big’ with the Synology RS2825RP+ 16 Bay, expandable 10GbE equipped and 25G Ready server solution. Arriving in the PLUS series, and therefore subject to the recent hardline storage media verification changes made by the brand for the 2025 series and onwards, the RS2825RP+ is clearly a very, very different solution and therefore perhaps reaching a target audience who are more receptive to it (maybe). Synology have a phenomenal history when it comes to their rackmount series – for many years it was just the rackstation series – but eventually we saw the UC, SA, FS and XS arrives.. which in turn is now rolling towards the enterprise challengers such as the Active Protect DP devices, the Gridstation (GS) devices and even a long desired and promised NVMe Flash series (the PAS range). So, PLUS series devices like the RS2825RP+ are occupying an increasingly squeezed area of the portfolio where buyers want comparatively affordable, scalable and capable storage. The changes by the brand on drive media support and verification do undercut this somewhat, so with that in mind, what has this new 3U Rackmount got to offer you in 2025 that makes it deserved your money and your data?

The Synology RS2825RP+ is equipped with an AMD Ryzen V1780B processor, offering a quad-core architecture with base and boost clocks of 3.35 GHz and 3.6 GHz, respectively. Designed for enterprise-grade workloads, the system includes 8 GB of ECC DDR4 memory in a single module configuration, which can be expanded up to 32 GB via two available slots. The rackmount chassis conforms to a 3U form factor and houses 16 front-accessible drive bays, supporting both 3.5” and 2.5” SATA formats. Networking capabilities include dual 1GbE ports and a single 10GbE port for high-speed data transfer, with a PCIe Gen3 slot offering further upgrade flexibility for additional NICs or storage controllers. According to Synology’s internal benchmarks, the unit delivers up to 3,519 MB/s sequential read and 1,790 MB/s write performance, which is suitable for multi-user environments requiring fast data access and sharing.

Engineered for sustained operation in business-critical environments, the RS2825RP+ incorporates three hot-swappable fans for effective airflow and dual redundant power supplies to mitigate downtime during hardware failures. The hot-swappable drive trays support online volume management, allowing for drive replacement or expansion without system shutdown. The power input is adaptable across 100–240V AC ranges, ensuring compatibility with global power standards. The system is further enhanced by a dedicated hardware encryption engine, allowing encrypted data processing without heavily impacting performance, making it practical for organizations handling sensitive or regulated data.

On the software side, the RS2825RP+ runs Synology’s DiskStation Manager (DSM), which supports a wide suite of data protection, business productivity, and infrastructure management applications. Included without additional licensing are tools such as Synology High Availability, which enables failover between identical units to ensure service continuity, and Snapshot Replication, which offers near-instantaneous recovery points for shared folders and LUNs. Hyper Backup extends protection to remote servers and public clouds with features like deduplication, data integrity verification, and multi-versioned backup scheduling. For IT environments reliant on virtualization, DSM integrates natively with VMware vSphere, Microsoft Hyper-V, Citrix, and OpenStack, with support for VMware VAAI and Windows ODX to offload and streamline storage operations.

Beyond infrastructure, DSM also serves as a collaboration platform. Synology Drive allows for real-time file synchronization across Windows, macOS, Linux, and mobile platforms, with granular permissions for enterprise-grade file governance. Users can collaborate using Synology Office, which provides a shared workspace for documents, spreadsheets, and presentations with unlimited versioning and cross-format compatibility. Communication features such as Synology Chat and Calendar are included, supporting encrypted messaging and team scheduling. Hybrid Share, an optional feature, combines on-premise access speed with cloud-based scalability, enabling multi-site deployments to efficiently manage shared files with a single global namespace.

The RS2825RP+ supports a maximum of 28 drives when paired with the RX1225RP expansion unit, enabling up to 560 TB of raw storage using currently available 20 TB drives. Storage flexibility is provided through support for Btrfs on internal volumes and a range of file systems on external devices. Multiple RAID configurations are available, including Synology Hybrid RAID, Basic, JBOD, and traditional RAID levels 0 through 10. SSD caching is supported via both SATA and M.2 NVMe SSDs, the latter requiring optional expansion cards. Volume sizes up to 200 TB are supported, although configurations exceeding 108 TB require the system to be upgraded to 32 GB of RAM, ensuring memory availability for managing large metadata and file tables.

A key constraint with the RS2825RP+ is Synology’s enforcement of verified drive compatibility. At the time of release, the system only allows initialization and full access to features when Synology-branded drives or those listed on its official compatibility list are installed. This closed ecosystem policy may limit adoption among users seeking to repurpose third-party or existing storage media. The restriction also affects advanced features such as SSD caching, drive health monitoring, and hybrid volume configurations, which are tied to Synology’s drive firmware and integration layers. The Synology RS2825RP+ offers a balanced mix of compute power, storage expandability, and data protection features suitable for centralized IT infrastructure in small to medium-sized businesses. Its high-speed throughput, enterprise-grade software suite, and support for virtualization and surveillance make it versatile for multiple deployment scenarios. However, organizations considering this model should weigh the implications of Synology’s drive compatibility enforcement against their existing hardware procurement policies.

Synology RS2825RP+ vs RS2821RP+ – A Significant Upgrade?

he RS2825RP+ is expected to replace the older RS2821RP+ in Synology’s 16-bay rackmount NAS lineup, and while both systems share the same 3U chassis size, drive bay count, and expansion support up to 28 bays, they diverge significantly in internal hardware. The newer model features a faster AMD Ryzen V1780B CPU with a higher base clock of 3.35 GHz (vs 2.2 GHz in the V1500B), along with 8 GB of ECC DDR4 memory pre-installed—double that of the RS2821RP+. The RS2825RP+ also includes a 10GbE port by default, something absent from the RS2821RP+, which instead comes with four 1GbE ports. While both models support PCIe expansion, the RS2825RP+ uses a newer generation processor with improved encryption offloading and virtualization potential, better suited to modern business applications with higher throughput demands.

However, the RS2821RP+ offers greater flexibility in terms of supported drive media. Although Synology recommends its own branded drives for this unit, it does not enforce the same strict hardware lock-in seen on the RS2825RP+. Users of the RS2821RP+ can utilize a broader range of 2.5” and 3.5” SATA HDDs and SSDs, including many from third-party vendors, without encountering initialization blocks or feature restrictions. This openness makes the RS2821RP+ a more attractive option for businesses with existing storage investments or those who prioritize long-term cost control and vendor neutrality. By contrast, the RS2825RP+ requires verified drives at launch, which restricts hardware reusability and may increase TCO for those transitioning from legacy systems.

When Will the Synology RS2825RP+ Be Released and the Price?

Ultimately, the RS2825RP+ represents a forward step in terms of raw performance and integrated networking capabilities, aligning with Synology’s broader push toward all-in-one systems with deeper integration and control. But that progress comes at the cost of flexibility, particularly in storage media compatibility. The RS2821RP+ may remain relevant for users seeking broader hardware compatibility, even as the RS2825RP+ replaces it in the official portfolio. Buyers will need to weigh the advantages of newer hardware against the limitations introduced by Synology’s tighter ecosystem approach.

All shared information online and inadvertent slips on the RS2825RP+ appear to indicate that the RS2825RP+ will arrive at a similar price point to it’s predecessor at around $3000-3499, and launching earlier in the eastern regions, but eventually rolling out globally in June.

Au Computex de Taïwan, Synology présente la nouvelle version de sa solution de « cloud privé » : le BeeStation Plus. Un produit très polyvalent qui se distingue des NAS par sa simplicité d'utilisation : n'importe qui peut le mettre en place.

Synology DS425+ NAS Revealed

The Synology DS425+ arrives as part of the company’s 2025 refresh of its popular DiskStation NAS lineup, positioned as a 4-bay solution for prosumers, content creators, and small business users who demand reliable private cloud functionality, media handling, and data protection tools—all in a desktop-friendly chassis. Succeeding the widely adopted DS423+, the DS425+ builds upon the same Intel Celeron J4125 architecture but introduces upgraded network connectivity and improved support for SSD caching, aiming to enhance performance across daily operations like file synchronization, multimedia streaming, collaborative document editing, and surveillance management. Running the latest version of DiskStation Manager (DSM), the DS425+ leverages Synology’s full ecosystem of services, including Synology Drive, Active Backup Suite, Surveillance Station, and Synology Photos. With this release, Synology is also doubling down on its strict hardware compatibility enforcement, limiting drive support to Synology-verified models only—a shift that may influence buyers with preexisting storage investments. Even so, the DS425+ offers a compact yet powerful platform for centralized storage, hybrid cloud collaboration, and secure file access from anywhere.

Synology DS425+ Hardware Specifications

At the heart of the Synology DS425+ is the same Intel Celeron J4125 processor seen in the DS423+—a quad-core, Gemini Lake-based chip with a base clock of 2.0 GHz and a burst frequency of 2.7 GHz. While this CPU has proven competent for basic NAS operations like SMB file serving, lightweight multimedia indexing, and DSM’s collaborative apps, its inclusion in a 2025 NAS release feels increasingly outdated. The J4125 first launched in 2019, and although its low power consumption and integrated hardware encryption engine remain attractive for entry-tier devices, it’s now noticeably behind in areas like video transcoding, AI-assisted tasks, and virtualization performance. For example, when running more demanding DSM features such as Surveillance Station with high-resolution streams, or multiple simultaneous file indexing operations via Synology Photos and Drive, this processor can quickly become a limiting factor, especially in multi-user environments.

Memory configuration hasn’t changed either, with the DS425+ shipping with 2 GB of DDR4 non-ECC RAM soldered to the board and a single expansion slot allowing upgrades to a maximum of 6 GB. This is a practical ceiling for general use—enough to handle several DSM packages like Synology Office, Drive, or Hyper Backup simultaneously—but it’s insufficient for users looking to run dockerized apps, virtual DSM instances, or advanced services such as Synology MailPlus in a more scalable manner. The non-ECC nature of the RAM also weakens the case for this NAS as a long-term professional solution, especially when handling sensitive or mission-critical workloads.

Networking is where the DS425+ makes a partial step forward, but not without caveats. It features a single 2.5GbE LAN port alongside a 1GbE port—an improvement over the dual 1GbE design of the DS423+—but a closer look reveals an intentional limitation. Unlike many other brands that now offer dual 2.5GbE ports for link aggregation or seamless failover at full speed, Synology’s decision to pair a 2.5GbE with a 1GbE appears less about cost or chipset restrictions and more about product segmentation. This asymmetric port setup discourages buyers from choosing the DS425+ over higher-tier units like the DS925+, which offers more symmetrical bandwidth and better expansion paths. From a hardware standpoint, there is no compelling technical reason this device couldn’t have included dual 2.5GbE—especially given its target audience of small business and prosumer users with growing data needs.

Storage connectivity fares better. The DS425+ supports four hot-swappable 3.5″/2.5″ SATA drives and adds two M.2 2280 NVMe SSD slots for cache acceleration—valuable for improving read/write IOPS, especially in workloads like media library scanning in Synology Photos or large document syncing in Synology Drive. These M.2 slots do not consume the main drive bays, preserving all four bays for primary storage—a practical advantage for users looking to maintain high capacity while improving responsiveness. However, it’s important to note that, per Synology’s 2025 compatibility policy, only Synology-branded SSDs (such as the SNV3400 series) can be used for either cache or storage pool creation, cutting out a wide array of affordable third-party options.

In terms of design, the DS425+ remains compact and energy-efficient, measuring 166 × 199 × 223 mm and weighing 2.18 kg. It uses two 92mm fans for active cooling, and power usage is modest—28.3W under load and just 8.45W in disk hibernation. Two USB 3.2 Gen 1 ports are available for external drive backups or peripheral support, and the unit is shipped with two RJ-45 cables, a power supply, and a 3-year warranty (extendable to 5 years in some regions). But while the physical build quality is solid, many of the internal hardware choices feel driven more by Synology’s desire to maintain product hierarchy than by a desire to fully meet evolving user needs in this segment.

Synology DS425+ vs DS423+ NAS – Much of an Upgrade?

On paper, the DS425+ and DS423+ appear remarkably similar—so much so that many users might question whether the DS425+ is a true generational upgrade. Both models use the same Intel Celeron J4125 quad-core processor, support up to 6 GB of non-ECC DDR4 memory, and house four 3.5″/2.5″ SATA bays alongside dual M.2 NVMe SSD slots. The physical dimensions, weight, fan configuration, and even the power draw figures are virtually identical. For many core use cases—such as basic file storage, Synology Drive collaboration, and multimedia backups via Hyper Backup—the user experience will feel nearly the same. This makes the DS425+ look more like a platform refresh than a reinvention.

However, the key differences lie in network connectivity and platform intent. The DS423+ features dual 1GbE ports with support for link aggregation or failover, while the DS425+ trades this for a mix of one 2.5GbE and one 1GbE port. While this technically increases the potential maximum throughput to 2.5Gbps, this hybrid setup seems designed to offer “just enough” improvement to distinguish the DS425+ without cannibalizing interest in higher-tier systems like the DS925+. For users with modern 2.5GbE switches, the DS425+ will offer a slightly snappier file access and faster backups—particularly when working with large media libraries or high-frequency synchronization tasks in Synology Photos or Drive. But those with symmetrical link aggregation setups may find the port layout frustratingly limiting.

Another critical shift is in Synology’s approach to drive compatibility. The DS423+—like most NAS units in the 2020–2023 era—offered relatively open support for third-party HDDs and SSDs, including Seagate IronWolf, WD Red, and enterprise-class models. Users would receive warnings when using non-verified drives, but DSM remained fully functional. In contrast, the DS425+ adopts the same restrictive policy seen in all 2025 Synology NAS systems, outright blocking DSM installation and pool creation with unverified hard drives or NVMe SSDs.

This has broad implications for cost-conscious users or those migrating from older Synology NAS units, as they may find that previously functional media is now flagged and unusable. Even within Synology’s own ecosystem, only select SKUs (e.g., HAT3300, HAT5300, SAT5200, SNV3400) are accepted without persistent alerts or functionality restrictions. While this change may support long-term system stability and vendor accountability, it narrows the appeal of the DS425+ as a flexible, user-driven NAS appliance.

Ultimately, the DS425+ is one of the smallest refresh/upgrades over the DS423+, largely just in its added 2.5GbE port. But for users already operating a DS423+, the performance incentives to upgrade are limited—unless specific use cases demand faster network throughput or tighter integration with Synology’s enterprise-leaning ecosystem. For first-time buyers, the DS425+ makes more sense if you are already choosing only the media the brand recommends and want a relatively low-noise, compact NAS with good multi-user potential, cloud tools, and basic virtualization support.

Synology DS425+ NAS – Software and Services

The DS425+ runs Synology DiskStation Manager (DSM), one of the most polished NAS operating systems available today, offering a blend of enterprise-level tools and consumer-friendly accessibility. Users can configure the device as a centralized file server, hybrid cloud gateway, backup vault, media hub, or private collaboration platform—all from within an intuitive web-based interface.

The system supports the Btrfs file system, enabling advanced data protection features such as file self-healing, quota management, and snapshot replication. With support for up to 256 system-wide snapshots and 128 per shared folder, users can roll back accidental deletions or ransomware-damaged data in seconds. Synology’s Hybrid Share also allows users to extend storage capacity to the cloud with on-demand file streaming and local caching, balancing scalability with local performance.

Collaboration is another strong point of the DSM ecosystem. Synology Drive provides a private alternative to Google Drive or Dropbox, enabling real-time file synchronization across devices and platforms, with versioning, sharing permissions, and browser-based access. Integrated with Synology Office, users can collaborate on documents, spreadsheets, and presentations with password protection and revision tracking.

These tools perform well even with modest hardware like the DS425+, and are ideal for distributed teams or remote workers. For communication, Synology Chat brings secure instant messaging with support for encrypted channels and message retention policies, while Synology MailPlus offers a fully-fledged private email server with support for up to 20 users (5 licenses included). These services transform the DS425+ from a simple storage box into a multi-role productivity appliance.

Synology also continues to invest in security and monitoring, with DSM 7.2+ adding features like Adaptive Multi-Factor Authentication (AMFA), which intelligently triggers additional login requirements based on user behavior and access patterns. Admins can leverage Active Insight, Synology’s cloud-based fleet monitoring system, to detect threats and performance anomalies across multiple NAS units, and even enforce policy-based snapshot creation during suspicious activity. For those managing backups, Synology’s Active Backup Suite covers Windows, Linux, VMware, Hyper-V, and Microsoft 365/Google Workspace, while Hyper Backup supports encrypted, deduplicated, multi-destination backups to local disks, other NAS units, or Synology’s C2 Storage cloud. Surveillance Station also comes bundled with two free IP camera licenses, and can support up to 40 H.265 1080p streams simultaneously—ideal for small-scale CCTV installations that want private, license-free storage.

Synology DS425+ NAS – Price and Release Date

The Synology DS425+ is scheduled to launch globally in June 2025, following an earlier rollout across Eastern markets beginning in the second half of May 2025. Based on its positioning and minimal hardware changes from the DS423+, it is expected to arrive with a similar MSRP in the range of $449 to $499 USD. This pricing places it firmly in the upper-middle segment of Synology’s 4-bay lineup, targeting users who need more performance and features than entry-level models offer, but without the broader expansion and higher price tags of units like the DS923+ or DS925+. However, with the inclusion of the new restrictive drive compatibility policy, buyers will need to factor in the additional cost of Synology-verified HDDs or SSDs, which could notably increase the total cost of ownership compared to similarly priced NAS systems that support a wider range of drives.

Synology at Computex 2025 – New NAS, Flash, and Surveillance Solutions Unveiled

At Computex 2025, Synology unveiled an extensive range of new hardware and storage solutions across both consumer and enterprise tiers. From compact desktop NAS to high-performance rackmount flash storage systems, the 2025 product line spans diverse use cases in home multimedia, business backups, AI-powered surveillance, and parallel active storage infrastructure. However, a significant underlying theme across this year’s announcements is Synology’s strict enforcement of Synology-verified storage media across both the Plus series and enterprise-class devices.

This ongoing shift in policy has raised concerns within the NAS community—especially among users who rely on third-party drives for flexibility and cost-effectiveness. Messaging around this storage validation system remains inconsistent, with key technical and strategic details still unclear. Nonetheless, this year’s lineup confirms Synology’s intent to consolidate hardware and media under its own ecosystem, even while expanding its presence into flash-first infrastructure and turnkey surveillance platforms.

PAS7700 – Flagship NVMe Enterprise Rackmount Storage

The PAS7700 marks Synology’s formal entry into high-performance all-NVMe storage for the enterprise sector. It is the most powerful product in the new Parallel Active Storage (PAS) series, designed with a dual-controller architecture and full end-to-end U.3 NVMe support. Each controller in the PAS7700 is powered by an AMD EPYC processor, supports up to 1TB of DDR4 ECC memory, and is capable of sustaining 30GB/s sequential throughput with over 2 million 4K random read IOPS. This architecture supports true active-active failover, high concurrency, and data consistency across large virtualized workloads or AI/ML pipelines.

Networking options include up to 4x 100GbE and 12x 25GbE ports (via optional NICs), and expansion is achieved using the PAX224, a 24-bay U.3 NVMe expansion chassis connected via HD-SAS 12Gb/s dual-link architecture. The PAS7700’s chassis is built to scale up to 216 NVMe drives for a maximum raw capacity exceeding 1.6PB, though real-world capacity will depend on drive model, RAID configuration, and overhead.

One of the more contentious elements is that, like all of Synology’s 2025 enterprise lineup, the PAS7700 mandates the use of Synology-verified U.3 NVMe SSDs. The drives shown on the show floor included 8TB Synology-branded U.3 SSDs, though Synology did not confirm their OEM origin, controller model, or endurance ratings beyond stating that they were optimized for sustained IOPS workloads. This storage lock-in policy has drawn criticism from users seeking flexibility in enterprise deployments.

PAS7700 Specifications

PAS3600 – Hybrid Flash Storage for Cost-Efficient Deployment

Positioned as the mid-range sibling to the PAS7700, the PAS3600 provides a more accessible entry into the Parallel Active Storage series by utilizing SATA drives rather than U.3 NVMe. Designed for hybrid flash deployment, the PAS3600 features dual controllers, each running an Intel Xeon processor and supporting up to 256GB of ECC DDR4 memory per controller. While it doesn’t match the raw performance of the PAS7700, it still delivers substantial throughput and redundancy suitable for enterprise virtual machine hosting, storage tiering, and backup environments.

Network connectivity includes support for up to 4x 25GbE and 8x 10GbE ports via optional NICs, with the system capable of scaling out using the PAX212, a 12-bay SATA flash expansion chassis. These expansion units also use 12Gb/s HD-SAS, and maintain redundant power supplies and dual data interconnects to ensure performance stability and non-disruptive scaling. Like the rest of Synology’s 2025 enterprise systems, the PAS3600 enforces the use of Synology-verified SATA SSDs, understandable in this sector of the industry and in line with this kind fo product.

PAS3600 Specifications

DVA7400 – AI-Powered Surveillance Rackmount System

The DVA7400 represents the most powerful surveillance solution Synology has introduced to date. It is the first in the DVA (Deep Video Analytics) lineup to be available in a rackmount form factor, making it suitable for larger, centralized surveillance deployments. The unit leverages an AMD Ryzen processor in combination with a dedicated GPU, enabling support for up to 100 camera streams and 40 simultaneous AI video analysis tasks, such as motion detection, facial recognition, and people counting.

In terms of connectivity, the DVA7400 includes dual 10GbE ports to ensure adequate bandwidth for high-resolution video ingestion and management. Additionally, it features a separate remote management interface, streamlining system oversight in enterprise environments. Internally, the system includes a dedicated AI processor with 190+ TFLOPS FP8 performance and 16GB of VRAM, allowing for real-time video indexing and recognition tasks.

As with most Synology surveillance systems, the DVA7400 includes a limited number of camera licenses by default. However, users deploying Synology-branded cameras benefit from license-free operation. Support for ONVIF-compliant third-party cameras is included but requires standard Synology Surveillance Station licenses. While the hardware is a significant leap forward, the system’s drive compatibility remains subject questionable, as the brand does not currently have an inhouse branded surveillance optimized HDD (eg comparable to WD Purple or Seagate Skyhawk – designed for much heavier WRITE over READ).

DVA7400 Specifications

FS200T – Compact All-Flash NAS for Quiet Environments

The FS200T, formerly expected as the DS625Slim, is now reclassified under the FlashStation series. This compact 6-bay NAS is designed for SSD-only deployments using 2.5″ SATA drives, and is aimed at users needing high-speed, low-noise storage in home studios or small office environments. Internally, it is powered by the Intel Celeron J4125, a quad-core processor that, while dated, includes integrated graphics. It is paired with 4GB of DDR4 memory, which is not ECC and may limit enterprise use.

Network connectivity includes 1x 2.5GbE and 1x 1GbE RJ-45 ports, a configuration that presents a noticeable bottleneck when combined with a 6-SSD RAID setup. No PCIe or expansion options are available. Despite the performance limitations imposed by its dated processor and limited bandwidth, the FS200T’s small form factor and flash-focused design make it a viable solution for read-heavy tasks or quiet operation environments where rotational noise from HDDs is undesirable.

FS200T Specifications

DS725+ – Dual-Bay Plus Series NAS with Expansion Support

The DS725+ is Synology’s latest 2-bay entry in the 2025 Plus series, offering modest upgrades over its predecessor, the DS723+. It features a 2-core, 4-thread AMD Ryzen R1600 processor, 4GB of ECC DDR4 memory (expandable), and includes two Ethernet ports: one 2.5GbE and one 1GbE. Unlike the previous model, the option for PCIe 10GbE upgrade has been removed, marking a notable downgrade in scalability.

Despite its small size, the DS725+ supports expansion up to 7 total drives using the Synology DX525 USB-C expansion unit, allowing users to migrate to larger RAID arrays over time. Internally, it includes two M.2 NVMe slots that can be used for either SSD caching or storage pools, enhancing read/write performance if properly configured. However, NVMe performance may still be limited by the relatively modest CPU and system architecture.

As with all 2025+ series units, this model enforces strict use of Synology-verified drives for optimal compatibility. This includes both the internal SATA bays and NVMe SSDs, aligning with Synology’s broader shift to a closed hardware ecosystem—an approach that continues to draw mixed reactions from the NAS community.

DS725+ Specifications

DS425+ – 4-Bay Multimedia NAS with Modest Refresh

The DS425+ is the 2025 refresh of the DS423+, aimed at SOHO and multimedia users seeking a 4-bay system with enhanced network throughput and M.2 NVMe support. Internally, the DS425+ continues to use the Intel Celeron J4125, a quad-core processor with integrated graphics, and comes with 4GB of DDR4 non-ECC memory. This model includes two Ethernet ports—1x 2.5GbE and 1x 1GbE—a somewhat disappointing choice that limits link aggregation potential and overall throughput compared to systems offering dual 2.5GbE.

The DS425+ includes two M.2 NVMe slots, usable for either SSD caching or as part of a storage pool. However, given the CPU and system bus limitations of the J4125, real-world NVMe performance may be constrained. There are no PCIe upgrade slots, meaning no pathway to 10GbE or further expansion beyond USB and the DX525 expansion unit.

Crucially, as part of the 2025 Plus series, the DS425+ requires Synology-verified drives for compatibility—both for its SATA and NVMe bays. This has led to pushback from users accustomed to broader drive support, especially in the mid-range where cost-effectiveness and flexibility are often more important than validation.

DS425+ Specifications

DS1525+ – 5-Bay All-Purpose NAS with Enhanced CPU and Expansion

The DS1525+ sits in the middle of Synology’s Plus series, offering a blend of scalability, multimedia handling, and business backup functionality. It upgrades the CPU from the DS1522+ by moving from the AMD Ryzen R1600 (2C/4T) to the AMD Ryzen V1500B, a 4-core, 8-thread processor that previously powered the DS1621+ and DS1821+. The system comes pre-installed with 8GB of DDR4 ECC memory, double that of its predecessor.

The DS1525+ includes two 2.5GbE RJ-45 network ports and supports the Synology Network Upgrade Module, which provides a pathway to 10GbE networking via a compact add-in module. This model also retains two M.2 NVMe slots for SSD caching or storage pool creation. It supports expansion to 15 total drives when connected to two DX525 expansion units, making it suitable for growing media libraries or multi-user project environments.

However, it still falls under Synology’s 2025 policy requiring Synology-verified storage media, both for the five primary SATA bays and the M.2 NVMe slots. This requirement continues to stir user debate, particularly in the mid-range segment, where third-party storage flexibility has historically been an expectation.

DS1525+ Specifications

DS1825+ – 8-Bay High-Capacity NAS for Power Users and SMBs

The DS1825+ serves as the high-capacity flagship in the 2025 Plus series, aimed at power users and small to medium businesses that require extensive storage and moderate processing capabilities. Like the DS1525+, it is powered by the AMD Ryzen V1500B (4 cores, 8 threads) and includes 8GB of ECC DDR4 memory by default. The unit offers two 2.5GbE RJ-45 ports, replacing the four 1GbE ports found in its predecessor, the DS1821+.

Storage can be expanded up to 18 total drives by connecting two DX525 expansion units via USB-C. The DS1825+ also includes two M.2 NVMe slots, supporting both SSD caching and dedicated NVMe storage pools. Unlike the DS1525+, it retains a standard PCIe slot, supporting full-sized 10GbE and higher NICs—with Synology now offering 25GbE and 50GbE upgrade cards, expanding its relevance in virtualization and high-bandwidth media workflows.

However, as with all devices in the 2025 Plus series, the DS1825+ enforces Synology’s drive verification system. Only Synology-verified SATA drives and NVMe SSDs are supported for optimal operation, and unsupported drives may be flagged or disabled in future DSM updates—a policy that continues to concern experienced users building mixed-brand NAS environments.

DS1825+ Specifications

DX525 – 5-Bay Expansion Unit for DS and Plus Series

The DX525 is Synology’s latest 5-bay expansion unit, designed for use with a wide range of their 2025 DS and Plus series NAS models. It connects via USB-C rather than the older eSATA standard, supporting newer devices such as the DS725+, DS425+, DS1525+, DS1825+, DS925+, and others.

It provides a seamless way to expand storage without migrating to a larger system or creating a new volume, and is fully integrated into DSM’s Storage Manager for volume extension and RAID expansion.

The DX525 supports both 3.5″ and 2.5″ SATA drives, with hot-swappable trays for quick replacement. While no network or processing capability exists on the unit itself (it’s entirely dependent on the host NAS), it can be used for extending existing RAID volumes or creating new independent volumes. This makes it useful for both capacity growth and tiered storage strategies.

DX525 Specifications

SNV5420 – Enterprise NVMe SSD for Sustained Caching Workloads

The SNV5400 is Synology’s newest high-performance M.2 NVMe SSD for caching and sustained-write workloads, positioned above the earlier SNV3400 series. Targeted at SMBs and enterprise deployments requiring high-speed caching, the SNV5400 delivers up to 660,000 random read IOPS and 120,000 random write IOPS, with a rated endurance of 2,900 TBW. It features end-to-end data protection and power loss protection, ensuring data integrity during unexpected shutdowns—essential for cache-tier applications in critical environments.

Unlike previous Synology NVMe SSDs, the SNV5400 also supports in-system firmware upgrades, reducing maintenance downtime during drive management or lifecycle refresh. It is available in at least one confirmed variant, though broader capacity options have not yet been fully disclosed. The controller used is reportedly the IG5636 FAA, believed to be a Gen4 NVMe controller, but Synology has not publicly confirmed full hardware details or OEM sourcing. In addition to the SNV5400 enterprise drive, Synology showed off a new high-performance M.2 NVMe SSD at Computex 2025 that appears to target heavier workloads than the SNV3400. It reportedly uses the IG5636 FAA controller, which supports PCIe Gen4, suggesting significantly higher throughput than their current Gen3 offerings. However, Synology did not publicly confirm specs such as endurance, capacity range, or the NAND type used.

This unnamed SSD is presumed to be part of a future SNV or new series aimed at advanced caching, AI workloads, or even storage pool applications in high-performance Plus and enterprise NAS models. Synology staff on the show floor were unable to confirm OEM origins or whether this model would be mandatory in future NVMe-capable systems.

HAT5300 20TB – Synology’s Largest Enterprise-Grade HDD

The HAT5300 20TB is the latest and highest-capacity addition to Synology’s line of enterprise SATA hard drives, extending the HAT5300 series for large-volume and high-workload environments.
