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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Synology DS1825+ NAS – Hardware Specifications

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

Component	Specification
CPU	AMD Ryzen V1500B (4-core, 64-bit, 2.2 GHz)
Memory (Pre-installed)	8 GB DDR4 ECC SODIMM (1 × 8 GB)
Memory (Max Capacity)	32 GB (2 × 16 GB)
Drive Bays	8 × 3.5″/2.5″ SATA HDD/SSD (Hot-swappable, except M.2)
M.2 NVMe Slots	2 × M.2 2280 NVMe SSD (for caching or storage pools, Synology drives only)
Max Drive Bays (with Expansion)	18 (with 2 × DX525 via USB-C)
LAN Ports	2 × 2.5GbE RJ-45 (Link Aggregation / Failover supported)
USB Ports	3 × USB 3.2 Gen 1
Expansion Ports	2 × USB Type-C (for DX525 expansion units)
PCIe Slot	1 × PCIe Gen3 x8 (x4 link)
Cooling	2 × 120 mm fans (user-replaceable; Full-Speed, Cool, Quiet modes)
Power Supply	Internal 250W PSU
Power Consumption	60.1W (Access) / 18.34W (HDD Hibernation)
Noise Level	23.8 dB(A) (Idle with Synology drives)
Dimensions (H × W × D)	166 mm × 343 mm × 243 mm
Weight	6.0 kg
Operating Temperature	0°C to 40°C
Drive Compatibility	Only Synology-verified HDDs and SSDs supported for full functionality

In terms of connectivity and expansion, the DS1825+ introduces two 2.5GbE RJ-45 LAN ports, replacing the older model’s four 1GbE ports. This change offers significantly higher throughput potential out of the box, particularly for multi-user environments or those running link aggregation. For further scalability, the unit includes one PCIe Gen3 x8 slot (x4 link), which supports 10GbE or 25GbE network interface cards. Additionally, Synology has swapped out the traditional eSATA expansion ports in favor of two USB-C-based connectors, used to link up to two DX525 expansion units, increasing total drive support to 18 bays.

Drive flexibility is offered through eight 3.5”/2.5” SATA drive bays and two M.2 2280 NVMe slots for SSD caching or storage pools – though we will return to the subject of just how flexible drives are in this system in a wee bit. The NVMe slots are not hot-swappable and are positioned internally, but provide a route for improving IOPS performance. Two 120mm fans handle cooling with configurable profiles, and the system operates at an idle noise level of 23.8 dB(A), slightly louder than the DS1821+ but still relatively quiet for an 8-bay desktop NAS. The DS1825+ also retains a 250W power supply, with typical access power consumption rated at 60.1W.

Synology DS1825+ NAS – DSM Software Specifications

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

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

Synology DS1825+ NAS vs the DS1821+ NAS

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

Drive Compatibility	Broad third-party drive support (with warnings)	Only Synology-verified drives supported

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

Synology DS1825+ NAS – Hard Drive Compatibility

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

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

SMART Monitoring – Non-Verified Drives	Full support	Limited or blocked (TBC)
Storage Manager Alerts – Non-Verified Drives	Warnings, dismissible	Persistent, cannot be cleared
Overall Compatibility Flexibility	High – mix-and-match drives allowed	Low – walled-garden enforcement

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

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

Synology DS1825+ NAS – Price and Release

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

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

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

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

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

Synology DS1525+ NAS – Hardware Specifications

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

Alongside this CPU is a pre-installed 8GB ECC DDR4 SODIMM module—double that of the DS925+—with support for up to 32GB across two slots. ECC (Error-Correcting Code) memory is still rare at this price point and capacity, and it adds another layer of data integrity assurance, particularly useful when running business-critical workloads like database hosting, mail servers, or multi-user collaborative suites. Whether you’re hosting Synology Office or leveraging multiple Docker containers, the default 8GB RAM already places the DS1525+ above its peers in out-of-the-box readiness, with upgrade options that scale appropriately with larger RAID arrays and SSD caching.

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

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

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

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

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

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

Synology DS1525+ NAS – HDD and SSD Compatibility

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

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

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

Synology DS1522+ NAS Release Date and Price?

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

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

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

WE LOVE COFFEE

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

Test Synology DS925+

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

Contenu de la boîte

Commençons par découvrir le contenu de la boîte :

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

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

Construction du NAS et design

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

Installation du NAS

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

Compatibilité des disques et tensions

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

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

Connectique

Le NAS dispose des interfaces suivantes :

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

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

Intérieur du DS925+

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

DSM 7.2

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

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

Performances du DS925+

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

Vitesses dans les transferts

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

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

À la suite de ces tests, une moyenne des transferts est calculée et nous la représentons sous forme de graphiques exprimée en mégaoctets par seconde (Mo/s). Plus le nombre est élevé, plus le NAS est rapide. Pour notre évaluation du DS925+, nous avons configuré un premier volume avec 2 SSD NVMe en RAID 0, puis en RAID 0 avec le chiffrement des données. Nous continuerons avec 3 SSD SATA en RAID 5. Enfin, nous finirons avec le RAID 0 et 2 câbles réseau.

RAID 0 (1 seul câble)

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

RAID 0 + Crypt (1 seul câble)

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

RAID 5 (1 seul câble)

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

RAID 0 (2 câbles)

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

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

Performances globales

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

Consommation électrique et nuisance sonore

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

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

Test de l’ASUSTOR AS6804T

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

Contenu de la boîte

Commençons par découvrir le contenu de la boîte :

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

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

Design et connectivité

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

Sur le plan de la connectivité, il offre :​

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

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

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

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

Intérieur du AS6804T

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

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

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

Installation du NAS

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

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

ADM 5.0

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

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

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

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

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

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

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

Performances de l’AS6804T

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

Vitesses dans les transferts

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

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

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

RAID 0

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

RAID 0 avec le chiffrement activé

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

RAID 5

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

Performances générales de l’AS6804T

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

Consommation électrique et nuisance sonore

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

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

Using Synology 1st Party Drives – Everything Works as Expected

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

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

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

New Installations Blocked for Non-Verified Drives

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

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

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

Below is the Synology DS923+ HDD Compatibility for comparison

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Expanding Existing Storage Pools with Unverified Drives is Blocked

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

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

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

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

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

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

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

Pool Expansion Using a 4TB Seagate IronWolf Drive

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

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

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

Pool Expansion Using a 4TB Seagate IronWolf Drive

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

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

Hot Spare Addition Attempt Using Seagate IronWolf Drive

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

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

Recovery of Degraded RAID Pool Using Seagate IronWolf Drive

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

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

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

Drive Removal and Reintroduction to Pool

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

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

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

Background: How Synology Got Here

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

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

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

Future Expansion & Unanswered Questions

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

Conclusion – CHECK DRIVE COMPATIBILITY BEFORE YOU BUY!!!

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

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

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

Reasons to Buy the Synology DS923+

Reasons to Buy the Synology DS925+

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

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

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

WE LOVE COFFEE

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

UGREEN DXP4800 Plus

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

Présentation & déballage

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

Configuration matérielle

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

Stockage :

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

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

Installation & OS

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

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

Utilisation au quotidien : 70 containers Docker

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

Domotique & maison connectée :

• Home Assistant
• Zigbee2MQTT
• ESPHome
• AppDaemon

Multimédia :

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

Téléchargement & automation :

• Transmission
• Prowlarr
• Recyclarr
• Authelia
• Autobrr

Sauvegardes & supervision :

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

Divers :

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

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

Performances

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

Comparaison & raisons du choix

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

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

Synology DS925+ NAS Review – Good News, Bad News

If you have been looking at making the move away from your cloud service provider to gain better ownership of your data, or are looking to upgrade your existing network storage system to something a tad more modern, chances are that Synology and the new DS925+ system have already appeared on your radar. Synology, a 25-year veteran in the world of network-attached storage, is arguably one of the biggest names in the game and has long commanded the largest market share in home and business purchases of NAS. The new DS925+ is the refresh of the late 2022 Synology DS923+, upgrading a few things and arguably clipping the wings of others. Whenever Synology refreshes its range of solutions every few years, it is normally a moment of largely universal praise as long-term Synology users consider upgrading their kit.

However, the Synology 2025 series of devices has been arguably more contentious and criticized internet-wide due to the brand’s changing stance on its support of hard drives in this newer generation, revamping the way in which users can choose which drives they can use in their systems. This change is still very much in its early days and could easily end up working out for the best — or being reversed — but nevertheless, the Synology DS925+ has arrived on the scene to a great deal more criticism and apprehension than most other Synology NAS devices ever launched in the brand’s two-and-a-half-decade-long history. But all of that aside, is the DS925+ actually any good? What can it do, what can’t it do, and does it deserve your money and your data?

Synology DS925+ NAS Review – Quick Conclusion

On a sheer hardware level, the Synology DS925+ is one of the strongest 4-bay systems the brand has ever released in this class. Whether compared to the 2023 refresh or earlier models, it delivers a noticeably better hardware package for the price. The long-overdue move to 2.5GbE is welcome, even if extremely late, and the upgrade from a dual-core, four-thread processor to a quad-core, eight-thread chip is ideal for VMs and containers. The continued inclusion of ECC memory (4GB, expandable to 32GB) reinforces its focus on reliability. DSM remains a standout — arguably still the best turnkey NAS OS on the market for stability, usability, and features. However, the removal of 10GbE upgrade options feels like a significant regression, especially as external 2.5G/5G USB network adapters are now commonplace. The hardware, while generally solid, will still feel underwhelming to users who expect more flexibility — especially given the price.

But it’s Synology’s aggressive stance on storage compatibility that casts the longest shadow. The DS925+ refuses to initialise DSM unless you’re using approved drives — a dramatic shift from previous generations using identical hardware that supported many third-party drives. Synology’s vague communication and inconsistent rollout of this policy only amplify user frustration. It’s hard to escape the sense that Synology is either hesitating to fully commit to bundling its NAS units with storage, or clumsily trying to control the ecosystem. The DS925+ is still a very good NAS, maintaining a decade-long price point while offering improved internals and software. But unless Synology quickly clarifies this compatibility policy, this release may be remembered more for controversy than capability — their biggest “Apple moment” yet, for good or for bad.

SOFTWARE - 10/10

HARDWARE - 6/10

PERFORMANCE - 8/10

PRICE - 9/10

VALUE - 8/10

8.2

PROS

Dual 2.5GbE Ports: Finally upgrades from 1GbE, offering significantly better bandwidth and support for link aggregation and SMB multichannel.
ECC Memory Support: Comes with 4GB ECC RAM (expandable to 32GB), rare at this price point and excellent for data integrity in long-term storage.
Quad-Core Ryzen V1500B CPU: A proven server-grade processor with 4 cores and 8 threads, ideal for multitasking, VMs, containers, and business apps.
Excellent Thermal Performance: Dual 92mm fans and a well-ventilated chassis keep internal temperatures low even under extended load.
Low Noise Operation: Impressively quiet in idle and moderate use; system noise is more dependent on drive selection than fan noise.
USB-C Expansion Support: Adds future-proof connectivity via the DX525 expansion unit, replacing the aging eSATA interface.
Top-Tier DSM Software: Ships with DSM 7.2 — widely considered the best NAS OS — offering excellent backup, cloud, and media tools with a polished UI.
EXCEPTIONAL License-free software in Active Backup and inclusive-license Surveillance Station Software

CONS

No 10GbE Upgrade Option: Removes the PCIe slot from the DS923+, eliminating any path to scale beyond 2.5GbE.
Comparatively underwhelming hardware compared to similarly priced Turnkey NAS solutions available from QNAP, UGREEN, Asustor, etc
Strict Drive Compatibility: Will not initialise DSM without Synology-branded HDDs or drives on the compatibility list (which we are still awaiting confirmation on re: verification). Brand messaging on which drives work now, later, long term, etc is messy at the moment

Synology DS925+ NAS Review – Design, Cooling and Power Consumption

The DS925+ maintains Synology’s long-standing chassis design, which has remained largely unchanged since around 2018–2019. It features a compact black plastic exterior with a solid metal internal frame that offers excellent durability and airflow.

The unit measures the same as its predecessors and blends easily into home or office environments. Ventilation is a central focus of the design, with large ventilated side panels, additional intake on the base, and a dual-fan array at the rear. These two 92mm fans replace the more typical single-fan setup found in many rival 4-bay systems, providing a more even and effective airflow throughout the unit.

The DS925+ also uses an external 100W power brick, though actual usage rarely approaches that limit.

In terms of noise, the DS925+ is impressively quiet during idle and moderate use — provided you’re using standard Synology-branded drives. With the system fully idle (RAID built, fans running at variable speed, no active users), the noise levels hovered around 36–37 dB(A).

When pushed with dual 2.5GbE connections and all drives under load, noise levels rose to about 48–50 dB(A), though much of this was attributed to the drives rather than the fans. Users planning to install high-capacity, enterprise-class drives like the HAT5300 series should expect higher operational noise. While the NAS fans remain relatively quiet, drive selection plays a significant role in the overall acoustic footprint of the system.

Power consumption during testing was also well within expectations. In a fully idle state, with base apps installed and the system not being accessed, the DS925+ drew approximately 28 watts. When fully loaded — with all four bays filled, SSDs installed, the CPU under strain, and both 2.5GbE connections active — consumption peaked around 62–64 watts.

These numbers align with what you’d expect for a Ryzen V1500B-based system with ECC memory and SSD support, though it’s worth noting that Synology’s own published power usage figures are lower. This discrepancy is likely due to Synology using SSDs in their testing rather than HDDs, which naturally draw more power and generate more heat.

Thermal performance on the DS925+ is particularly strong, especially considering the plastic enclosure. At the one-hour mark under moderate usage, system temperatures ranged from 35°C to 39°C.

After 24 hours of intermittent access, including background tasks like scrubbing and package installation, the system maintained a stable range of 34°C to 36°C. The dual rear fans, in conjunction with the well-ventilated chassis, clearly play a key role in keeping the internal environment controlled. These results are especially encouraging given that many competing 4-bay NAS systems still ship with only a single rear fan and less efficient airflow paths.

Bottom line, the DS925+ offers a refined, if familiar, physical design that prioritises quiet operation, effective heat management, and reasonable power efficiency – something this product series has always excelled at vs it’s competitors (such as the QNAP TS-464, Asustor Lockerstor series or still new UGREEN DXP4800. While Synology hasn’t reinvented the chassis, the dual fan design, ample ventilation, and strong thermal numbers show thoughtful incremental improvements. However, as with most NAS systems, the overall experience is still influenced heavily by drive selection — particularly in terms of noise and power draw. For users seeking a low-noise, power-efficient solution with excellent temperature control, the DS925+ remains a very well-balanced option in the 4-bay NAS category.

Synology DS925+ NAS Review – Ports and Connectivity

The Synology DS925+ supplies a fairly middling range of connections, depending on your point of view. Hot take: if you were to compare this device against previously released Synology devices, there is actually something of a mixed bag here to like as well as dislike. Likewise, if you compare the device to the available range of NAS solutions from this brand’s competitors, you could probably be especially critical of what you see here. However, there are some interesting features worthy of note, and given Synology’s heavy emphasis on internal operations and remote access priorities, it isn’t a huge surprise that the physical connections on this modest system are likewise pretty understated.

The front of the system features a single USB Type-A 5 Gb per second connection port that is predominantly used for connecting storage drives to make them remotely accessible. Synology has largely reduced the utility of these USB ports on their systems to simply storage and connection of a UPS system. So you can forget about utilising the majority of PC USB peripherals, directly connecting to the device over USB, or even simple network USB adaptors — a particularly unpopular choice by Synology in their DSM 7 update a few years ago. That said, the USB connectivity integrates extremely well with the backup software on this system, allowing for scheduled and automated backups to be conducted via this port, with particularly sophisticated filter customisation as needed.

Flipping the device around shows us the more important system connections available on the DS925+. The big headline here is Synology finally — finally — upgrading this system and the 2025 generation moving forward with 2.5 GbE ports, rather than the pedestrian and outdated 1 GbE network ports. The system features two ports, and the DSM platform allows for merging of these connections via protocols such as port trunking, link aggregation, load balancing, and SMB multi-channel, as well as failover as needed. These are certainly a welcome — if hugely overdue — upgrade on this system (when the bulk of this brand’s hardware competitors rolled out 2.5G as much as five years earlier at a similar price point). But at the very least, this does mean that users are going to be able to enjoy fuller saturation of the four SATA drive connections on this system more so than in previous generations of this product series.

That said, Synology giveth and Synology taketh away! Even though Synology has upgraded the default network connections on the device, they have removed the optional mini PCIe upgrade slot that was available on the DS923+ before this. This is going to be a huge kick in the ass for a lot of users who were considering purchasing this device over the DS923+ predecessor, as it means that the ability to scale up the network connectivity toward 10GbE is now not available on this system. So despite the fact that this system can now comfortably accommodate over two and a half times the external network bandwidth of its predecessor out of the box, it also means that the effective potential maximum network connectivity that a user could hope to achieve down the line has now been effectively halved! Again, this was always an optional upgrade in its predecessor, but it was an extremely welcome one for many — and given that even their value series of hard drives can hit between 180 and 200 MB per second per drive, that means that even the most inefficient RAID cluster with these drives will almost certainly still oversaturate the base twin 2.5G connections that the base model has. Therefore, you are being somewhat bottlenecked down the road because of this lack of network adapter upgradability. And don’t even get me started on the throttling that you will likely encounter if utilising M.2 NVMe RAID pools on the DS925+ via remote network connectivity.

Finally, we find another change in this product over its predecessors, and that is the shift in expandability on this system toward a USB-C output. This USB-C provides 5 Gb/s connectivity and only supports the new DX525 expansion chassis, which costs around $350 to $450 depending on where you are in the world and your local tax rate. Synology has always afforded the ability to expand this product series with a 5-bay expansion, either to spread the RAID configuration or mirror it appropriately, so this is a welcome — if expected — integration in the DS925+ class nonetheless, and it allows for greater storage scalability over the years.

All that said — and I’m sorry to be negative again — I can’t help but feel that this expandability is still being handled a tad clumsily. For a start, even at USB-C, that still means that the five SATA drives that the expansion supports are effectively capped in their maximum external bandwidth potential. And although you were never really going to enjoy greater speeds regardless — due to the 2.5 GbE network connectivity anyway — there are definitely going to be users who are sad about this further bottleneck on the performance of those drives in the expansion.

The fact that Synology did not implement an improved means of network connectivity — perhaps via 10 GbE or USB 3.2 Gen 2 (almost certainly due to a CPU choice limitation) — is really disheartening. Likewise, since this expansion now connects over standard USB, why are we still only limited to one expansion, and only via that specific USB port? The fact that we could have increased the number of expansion devices in line with the other available USB ports would have been tremendously appealing to users thinking about the long-term scalability of their system. And given that USB ports are common (if a little more restrained) on practically every single Synology NAS, this is a real missed opportunity to add storage expandability — and I can only assume it’s a conscious and deliberate choice by the brand to maintain their portfolio segmentation.

Bottom line: I love that this system is expandable, and I do like that a number of the features of the system have been improved over its predecessor. But as I mentioned earlier, the general standard of connectivity on the DS925+ is still awfully restrained when you take even a casual glance at the rest of the market right now. It only further underlines the fact that Synology is doubling down on this system more in terms of its software and capabilities rather than its hardware — which is no doubt going to please the bulk of users looking at this system who just want a stable NAS that does its job, but will nonetheless annoy enthusiasts and prosumers who want to make the most of their hardware.

Synology DS925+ NAS Review – Internal Hardware

If there is one area that Synology consistently gets criticised for, it is the hardware they choose to use. It can definitely be argued that, as a NAS is a 24/7 system, manufacturers need to focus heavily on the efficiency of hardware and keep things as high-performance as possible at the lowest cost of power consumption and hardware utilisation. Equally, it could be argued that because Synology prioritises software over hardware — and wants to maintain tightly locked price points in its portfolio — over the years they have had to be awfully tactical in the hardware they choose to use across their product lines. All these things no doubt play their part, but nonetheless, it all adds up to a system that is not exactly going to blow anyone away if they are looking at the hardware specs as the chief buying point for their first server or an upgrade.

The first thing I want to discuss is that CPU! Keeping things positive, this is a four-core, eight-thread AMD embedded server-class Ryzen processor. In human speak, that means this CPU is designed for server utilisation — chiefly for file processes and for spreading itself quite thinly across multiple processes and tasks with efficient ease. Additionally, this processor has already been utilised and heavily investigated by Synology since its first rollout at the higher end of the SMB section of its portfolio as early as 2019/2020 — so the brand has extensive experience in getting the very most it can out of this processor. Additionally, Synology has often taken the hardware configuration of a higher-tier solution in their portfolio and — between multi-year refreshes — then passed this hardware configuration down into lower and more affordable tiers over the years. So this processor’s appearance, and its refresh of the previous R1600 dual-core, four-thread processor in the DS923+ predecessor, is not unexpected — and for many, actually quite welcome.

Here is how the R1600 in the DS923+ 2022/2023 Release compares with the V1500B in the DS925+ Refresh:

Likewise, this processor provides the full spectrum of system software services and abilities that DiskStation Manager 7.2 has to offer. There is not a single DSM application or component that you are unable to take advantage of on this hardware spec. Alongside that, this CPU will comfortably allow for a decent number of VMs, containers, file processes, and simultaneous proprietary application services to all run at the exact same time — despite this system’s modest stature. Integrated graphics processors have been phased out from this particular product family — and this is the second refresh of the product line to remove integrated graphics-equipped processors — instead moving this kind of deployment to its smaller and more multimedia-focused DS425+ and DS225+ models. There are mixed results to this of course, especially given that the DS925+ has removed network upgradability — which I think may well leave quite a lot of CPU bandwidth by the roadside somewhat. But given the similarity in price point between this system and previous refreshes of this 4-bay series, I’m not, on the whole, unhappy with this processor. It’s just a continued departure by the brand away from classic 4-bays like the DS920+ and DS918+.

Alongside this processor, the system arrives with 4GB of DDR4 ECC SO-DIMM memory. ECC memory, in most network storage tech circles, is absolutely paramount for high-volume and high-frequency file transfers and long-term storage. Very, very few systems at the $550 price point ever include ECC memory in a turnkey NAS solution, and I know this is something that has always met with phenomenal praise by system integrators (SIs) who recommend Synology for simple and effective business storage requirements. Additionally, this memory can be scaled up all the way to 32GB, which — once you factor in the eight threads on this processor being spread out across multiple processes — is pretty darn good when you think about the scale of this system physically versus the potential of that software! Of course, in line with several other Synology policy changes over the years, the system is strictly compatible with only first-party memory upgrades from Synology — which you will not be surprised to hear are notably more expensive than third-party options in the market from Crucial, Kingston, and Samsung. This has always been something that has been met with notable disapproval by many, but Synology defends this by repeating the point that they want a single-party ecosystem, and the DS925+ is an appliance that centres around being smooth, efficient, and easy to deploy.

At the base of the system, we find the two M.2 NVMe slots that allow you to install one or two 2280-length SSD drives that can be utilised for read & write caching and/or use as storage pools. The benefits of utilising caching — when used in conjunction with the ECC memory and that file-transmission-focused processor — are pretty bloody significant, and it does allow for a degree of versatility and optimisation for users once again focused on high-volume and high-frequency data storage needs 24/7. But the use of these bays for storage pools is still pretty underwhelming at launch, and a big part of this is — much like other system upgrades — these M.2 bays are limited to only using Synology NVMe SSDs. This is a limitation compared with the predecessor, and while it’s a small tweak over the status quo, it becomes a significant one when you factor in that, currently, the only Synology M.2 NVMe offering is the heavily durability-focused but write-performance-weak SNV3400 series.

No doubt, as Synology rolls out more proprietary media-focused systems in their 2025 lineup and continues to expand the offering of branded storage media, the brand will eventually roll out a much more performance-rich NVMe SSD (perhaps the SNV5300 or SNV7400). But until that happens, these bays are a little restricted in terms of compatible media to really make the most of their capabilities right now.

Bottom line: for the money you’re laying down here — and if you factor in the value and quality of the software — many are going to be happy to overlook the comparatively underwhelming internal hardware on offer here when comparing it against the number of competitors on the market that focus on the hardware more than the software. If you’ve followed the brand for a long time, you’ll probably agree that what we’re seeing here is fairly standard for what this brand tends to include in their systems, and therefore you may be happy to give them a pass on this. But if this is a system that is chiefly being sold on its software and services — let’s discuss those a great deal more!

Synology DS925+ NAS Review – DSM Software and Services

The DS925+ arrives preloaded with Synology’s DiskStation Manager (DSM) 7.2, the latest version of their industry-leading NAS operating system. DSM has long been praised for its clean, intuitive interface that makes it easy for even novice users to get started while still offering deep functionality for IT professionals. Everything from user account creation, network configuration, file sharing, and app management is presented through a streamlined browser-based GUI. It’s an OS that feels more like a well-polished desktop environment than a traditional NAS UI, and the DS925+ handles it with ease thanks to its Ryzen CPU and ECC memory.

DSM offers comprehensive file management through File Station, and supports standard protocols such as SMB, FTP, WebDAV, and Rsync. Whether you’re accessing files locally or remotely, the experience is responsive and customisable. File previews, right-click menus, and in-browser streaming of media files all work out of the box, while features like folder-level encryption, WORM (write once, read many), and fine-grained user permissions ensure strong data governance. The included Synology Drive application further enhances file syncing and backup capabilities across multiple platforms — Windows, macOS, Linux, Android, and iOS.

Synology has also baked in powerful backup and disaster recovery tools into DSM, with Active Backup for Business standing out in particular. It supports full OS and file-level backups for Windows, Linux, virtual machines, SaaS apps like Microsoft 365 and Google Workspace, and even other NAS devices.

Best of all, it requires no additional licenses for most features. Hyper Backup provides flexible multi-destination backup options, while Snapshot Replication protects against ransomware or accidental deletions by allowing near-instant recovery of shared folders or entire volumes.

For users focused on multimedia, DSM supports apps like Synology Photos, Audio Station, and Plex Media Server. While Synology has scaled back some native media tools like Video Station, DSM remains highly compatible with third-party platforms. Container Manager and Virtual Machine Manager allow for lightweight app deployment and virtualisation without a license fee — with the DS925+ capable of running multiple Docker containers or virtual DSM instances simultaneously. Synology’s mobile apps also tie in seamlessly with DSM services, offering secure access to files, surveillance feeds, photo backups, and more.

Ultimately, DSM is the DS925+’s strongest asset. Synology’s software-first approach continues to pay off, delivering an experience that’s miles ahead of most competitors in terms of polish, security, and integration.

Whether you’re a home user setting up private cloud storage or a small business deploying multi-site backups, DSM remains the gold standard in NAS operating systems. For many users, the value of DSM alone justifies choosing Synology — even when hardware compromises or compatibility limitations exist.

Below is a breakdown of how the Synology DS925+ improves upon the software and service support of the DS923:

Synology DS925+ NAS Review – Storage and Compatibility

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

In 2022, when the brand rolled out an update in DSM 7.1 that changed the system status for any NAS using non-Synology-approved drives to display a warning state, the wider Synology user base was in uproar — whether it was because they didn’t like the brand’s position on dictating which drives worked and which didn’t, or because, as a system integrator or admin, they suddenly had a bunch of clueless users complaining that the system had gone from green to amber. Synology would eventually roll this back and, although they never reversed the policy of warning users that their drives were not on the compatibility list, they did soften the system’s response. Fast forward to now, and the brand is again changing its third-party drive verification and compatibility methodologies internally. The 2025 series and onward will strictly require drives that are already listed on Synology’s compatibility list. So why is that a problem right now?

Well — twofold. First, right now only Synology HDDs and SSDs are listed on the official DS925+ compatibility pages, despite the hardware inside the DS925+ being identical to previous Synology hardware from both the 2020 and 2023 generations — both of which still list many Seagate, Western Digital, Toshiba, Samsung, Kingston, and more drives. That does look a little off.

But the second, more serious reason is Synology’s aggressive approach to this policy. Previously, if you used an unverified drive, the system would warn you in Storage Manager after setting up DSM, informing you that the drives were not verified by Synology and that using them might put your system in an unsupported state — potentially limiting any after-sales or technical support the brand could offer. The 2025 series, however, currently will not even allow you to initialise the system out of the box if you are using non-Synology hard drives.

This will no doubt be problematic with e-retailers and online dealers — unless they make this strict compatibility policy exceptionally clear. The rollout of these changes across the 2025 series has been inconsistent and unclear at best. It first emerged via a press release on Synology’s German website, despite now being mentioned in different areas of global Knowledge Centers. Even now, as I write this review, although the official Synology DS925+ page is live, the wording surrounding unverified drives and their support on this new system remains very diplomatic and vague.

It might well be that weeks or months from now, as this system rolls out, the list of drives supported on the Synology DS925+ and other NAS systems in the 2025 series will eventually include third-party drives from WD and Seagate. Nevertheless, the messaging has been profoundly unclear and inconclusive. Synology has always supported third-party drives in numerous systems before this one — systems that, as mentioned earlier, have exactly the same hardware as this system and run the latest version of DSM as well! If their verification and compatibility tests have changed, they need to make this a great deal clearer and more justifiable to users. If they have numerous reported cases of unverified drives wreaking havoc, they need to share these results.

On the flip side, many could argue that as long as Synology provides a range of hard drives and SSDs that are comparable in price and performance to those of third parties, then losing access to third-party drives is no big deal. Unfortunately, that is not globally true. While there are some examples of Synology media being at the same price and performance level as third-party options, the availability and pricing for these drives is nowhere near as consistent as those of third-party brands — and for many, that forms one of the greatest long-term issues for their storage.

If you have an existing Synology NAS that is using third-party hard drives, you are still able to migrate drives over to the new system physically. This will allow for an easy upgrade path for existing users — but it’s not really a tremendous benefit for those who were considering the DS925+ as their first shiny new NAS system.

Migrating your drives physically from an older Synology NAS to a new device allows you to proceed – but with warnings

In discussions with numerous people online, a lot of us agree that Synology is kind of half-assing something here. If they’re going to support third-party hard drives and SSDs on their systems, then they need to do it — and do it as well as they have before. Revamping a verification system in-house that many would argue didn’t need revamping in the first place seems silly at best and calculated at worst. Otherwise, if they want to commit to recommending their own media above all else, just go the whole hog: bundle the solutions as standard, pre-populated, and maybe even extend the savings too. Interestingly, the changes in system recognition of non-listed compatible drives seems to only impact HDDs at this time. If you first-time-setup your Synology DS925+ NAS with SATA SSD(s) – you are still able to initialise the NAS as before – albeit with red and amber warnings on the storage GUI:

We’ve already seen the brand’s stance on storage media play out this way with M.2 NVMe SSDs in the 2023 generation and later — only allowing storage pool deployments if you use Synology-branded drives and no others (yet still supporting third-party drives for caching, if you like). Synology knew this was going to be an unpopular policy, but obviously, this is part of their wider roadmap. The brand themselves state that this is a move toward redefining their platform — away from being just hardware and toward becoming a full and complete data appliance.

I do also want to comment on the way that the system presents the use of 3rd party drives, even when used in authorized ways (eg using SATA SSDs in initialization does NOT bar you from their use the way HDDs are when not on the compatibility pages – likewise when you use drives from an older Synology NAS via physical migration to the DS925+).

When you DO have non-synology confirmed drives in the system via these methods – the presentation of DSM is notably more negative and aggressively alarming. Red and Orange text, icons, warnings, alerts and triggering words like ‘At Risk’ are thrown around far, far too liberally.

As mentioned several times, this might all turn out to be a storm in a teacup, and Synology may expedite verification of hard drives on their compatibility lists — or even U-turn on this decision entirely and pretend it never happened. Either way, a lot of users — new and old — have based significant purchasing decisions on this change by the brand.

Synology DS925+ NAS Review – Conclusion & Verdict

On a sheer hardware level, the Synology DS925+ is largely a superior system out of the box compared with any previous 4-bay Synology NAS solution released by the brand in this class series. Whether you’re comparing how much has scaled up in this refresh of the previous 2023 series release, or just generally looking at the standard of what you get for your money here, for the most part — in terms of hardware — it is better than the majority of systems that came before it. The long, long overdue upgrade to 2.5 GbE network connections is welcome (even if the brand is especially late to the party here). The upgrade from a dual-core, four-thread processor to a quad-core, eight-thread processor is certainly going to please those VM and app sandbox/container users greatly. And the continued implementation of ECC memory at 4GB, with scalability up to 32GB, only further doubles down on this point.

DSM continues to impress and still holds itself comfortably as the premier turnkey NAS software solution on the market — both in terms of its feature set as well as its stability and usability. The lack of 10GbE scalability is a bitter pill to swallow when many of us were just getting used to the idea of Synology engaging with 10G NIC upgrades at this hardware level. And although this feature is promised on the DS1525+, it is still something of a pain point on the DS925+ — especially now, as $25 USB-to-2.5G and 5G network adaptors are very much a thing and widely supported everywhere. But for the most part, the hardware is consistent — if a little underwhelming. Synology solutions, though, have never been about the hardware. But beyond this is where the rather curious and unpopular choices by the brand regarding storage compatibility and verification in DSM and the 2025 series in general really end up marring what could have been a very confident release by Synology in the DS925+.

I hope that months from now, this matter is just a memory, and Synology has either expedited the verification of third-party drives or reversed the majority of these decisions due to public outcry. In truth, I think a lot of users would probably have preferred the DS925+ to roll out pre-populated with storage media — much like their new BeeStation series does. Going down the road of restricting which drives people can use was never going to be popular, so either don’t do it or fully commit to it. There is, of course, the argument that these drives — which were previously verified and confirmed working on the exact same hardware (CPU, motherboards, network deployment, and software utilisation) in previous generations — have mystically now been deemed unverified on the new 2025 series and its genuinely identical hardware to what came before. It’s an odd line in the sand to draw, a message that has been delivered messily, and I do not envy the Synology marketing team having to shape the narrative on this one. The bottom line is that the DS925+ is still a very, very good Synology NAS system, and although it loses a few bells and whistles compared to its predecessors, it still delivers very well on a platform that has maintained the same price point for its scale for more than a decade — despite changing world events. But until Synology clears up exactly how and why they’ve changed drive verification on this system in a clear and transparent fashion, I do think this is a NAS device that is going to pale in comparison to the deployment and overall sales of its predecessor — and the brand needs to sort this quickly.

The DS925+ is a good NAS for the money in terms of hardware and software, but we may well be witnessing Synology’s biggest “Apple moment” — for good and for bad.

Cette année, la journée mondiale du mot de passe est tombée le 1er mai. Pas de bol, je n’avais pas préparé d’article pour ce jour, donc il parait aujourd’hui. Mieux vaut tard que jamais, diront certains. J’ai décidé de partager mon expérience, donc n’hésitez pas à en faire de même en commentaire.

Bonnes pratiques pour ses mots de passe

Comme c’est la journée mondiale du mot de passe, il est important de rappeler quelques règles essentielles pour protéger vos comptes en ligne :

• Créez des mots de passe forts de 12 caractères minimum, en mélangeant lettres majuscules et minuscules, chiffres et symboles. Plus c’est complexe, mieux c’est !
• Ne jamais réutiliser les mots de passe sur plusieurs sites. Je sais, c’est plus facile à dire qu’à faire, surtout si l’on doit tout retenir de tête.
• Utilisez un gestionnaire de mots de passe (gratuit ou payant, il en existe beaucoup) pour stocker et générer des mots de passe uniques.
• Ajoutez l’authentification multifactorielle (MFA) lorsque c’est possible. Cela ajoute une couche de sécurité supplémentaire, même si votre mot de passe est compromis.

Mon expérience : gestionnaires de mots de passe

Au fil des années, j’ai utilisé plusieurs outils pour gérer mes mots de passe. Parmi les derniers, je peux citer KeePass, LastPass (que je déconseille pour diverses raisons de sécurité) et surtout Bitwarden. Ce dernier reste mon favori : il est sécurisé, multiplateforme, très complet, gratuit dans sa version de base, rapide et peut même être auto-hébergé sur un NAS. Pour ma part, j’ai environ 400 mots de passe enregistrés (impossible de tous les retenir). Du coup, j’ai un identifiant et un mot de passe fort uniquement pour accéder à mon coffre-fort Bitwarden.

Personnellement, j’utilise Bitwarden sur mon NAS depuis plusieurs années grâce à Docker (Vaultwarden). Cela signifie que mon coffre-fort de mots de passe est hébergé uniquement chez moi, ce qui me rassure côté confidentialité et sécurité.

Pour le quotidien, j’utilise l’extension Bitwarden dans mon navigateur préféré (Firefox) ainsi que l’application officielle sur mon téléphone. Cela me permet d’accéder à mes mots de passe où que je sois, sans sacrifier la sécurité.

Quelques mots de passe « hors ligne »

Cependant, je ne mets pas tous mes mots de passe dans Bitwarden. Oui, je l’avoue, je suis un peu parano sur les bords. Certains mots de passe ultra-sensibles, comme ceux de ma banque en ligne, l’accès à mes PC à la maison et au travail, ou encore celui de mon NAS, ne sont stockés nulle part (sauf dans ma tête, tant qu’elle fonctionne). C’est une précaution supplémentaire, même si cela demande un effort de mémoire.

Et vous, quelles sont vos habitudes pour gérer vos mots de passe ? Utilisez-vous un gestionnaire ? Si oui, lequel ? N’hésite pas à laisser un commentaire

Minisforum MS-A2 PC Review

The Minisforum MS-A2 is the latest entry in Minisforum’s growing lineup of workstation-focused mini PCs. First shown at CES 2025, the MS-A2 builds on ideas introduced in earlier models like the MS01 and MS-A1 but shifts toward an AMD platform, offering users a choice between two high-end Ryzen 9 CPUs. Rather than aiming for the ultra-compact form factor associated with traditional mini PCs, the MS-A2 leans into expandability, performance, and connectivity. It offers multiple M.2 storage slots, PCIe expansion, dual 10GbE SFP+ ports, and a layout designed to accommodate heavier workloads. Throughout this review, we’ll take a closer look at the internal hardware, external connections, design choices, performance in benchmarks, and how it compares to the MS-01, before wrapping up with a final verdict on where it fits in today’s mini PC market.

Minisforum MS-A2 Review – Quick Conclusion

The Minisforum MS-A2 is a powerful mini workstation that targets users needing high CPU performance, network scalability, and internal expandability rather than external device flexibility. Equipped with Ryzen 9 9955HX or 7945HX CPUs, up to 96GB DDR5 memory, triple M.2 slots, and dual 10GbE SFP+ ports, it offers strong capabilities for demanding workloads like virtualization, server hosting, and content creation. However, the absence of USB4/Thunderbolt 4 and observed inconsistencies in storage write speeds mean it may not fit every use case. Positioned alongside rather than as a replacement for the MS-01, the MS-A2 is best suited for buyers who prioritize multi-threaded performance and dense internal storage options in a compact form factor.

Minisforum MS-A2 Review – Internal Hardware

Inside the Minisforum MS-A2, users have a choice between two processors: the AMD Ryzen 9 9955HX or the Ryzen 9 7945HX. Both CPUs offer 16 cores and 32 threads, with a maximum boost clock of 5.4GHz. The 9955HX uses the newer Zen 5 architecture, while the 7945HX is built on Zen 4. The two processors are close in raw specifications, but the Zen 5 variant benefits from a more efficient 4nm process and updated IPC improvements. Integrated graphics are handled by the Radeon 610M on both options, offering basic graphical capabilities suitable for general-purpose workloads, but not designed for high-end gaming or intensive GPU compute tasks.

Memory support on the MS-A2 is generous for a mini PC. It features two DDR5 SO-DIMM slots, allowing up to 96GB of RAM. Systems based on the Ryzen 9000 series CPUs support memory speeds up to 5600MT/s, while Ryzen 7000 series CPUs are rated for up to 5200MT/s. This flexibility gives users room to configure the system for heavy multitasking, virtualization, or memory-hungry professional applications. However, the MS-A2 does not support ECC memory, which may be a consideration for users needing strict data integrity for server or professional workstation tasks.

Storage options are extensive, with three onboard M.2 slots available. One slot supports U.2 or standard M.2 NVMe drives up to 15TB (PCIe 4.0 x4), while two additional M.2 slots support either NVMe or SATA drives up to 4TB each.

All slots run at PCIe 4.0 speeds, ensuring strong storage performance for workflows like video editing, virtual machines, or database management. Minisforum also hints at future expandability through an optional accessory that would allow for the installation of up to six M.2 drives, although cooling for such configurations is still under development.

Cooling inside the MS-A2 is designed to accommodate the considerable thermal output of the CPUs and storage devices.

A dedicated CPU cooling system with copper piping and a 12V fan handles the processor, while a second 5V fan directly cools the SSD slots and the 10GbE controller. Despite the compact space, Minisforum has optimized airflow reasonably well, but heat sink space is limited, especially for M.2 drives, making active airflow critical.

Overall, the internal hardware layout focuses on balancing high performance with maintainability, though users planning extensive upgrades should be aware of space and thermal limits.

Minisforum MS-A2 Review – Ports and Connections

The Minisforum MS-A2 is equipped with a wide range of external connectivity options aimed at both workstation and server-style deployments. On the front panel, users will find two USB 3.2 Gen 1 Type-A ports, one USB 2.0 Type-A port, a 3.5mm four-in-one audio jack, and the system’s main power button with integrated LED indicator. This arrangement makes it easy to quickly connect peripherals like external drives, keyboards, or headsets without reaching around to the back of the device.

The rear panel is where the MS-A2’s workstation orientation becomes more evident. It features two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 2 Type-C ports with Alt Mode DisplayPort 2.0 support, a single HDMI 2.1 output capable of 8K60 video, and dual 2.5GbE RJ45 ports powered by Intel controllers. More notably, the system also includes two 10GbE SFP+ ports driven by an Intel X710 controller, opening up high-speed networking options typically reserved for larger systems.

This broad mix of ports covers a wide range of use cases, from high-resolution displays to enterprise-grade network environments.

The MS-A2 also provides PCIe expansion via a PCIe Gen 4 x8 physical slot, allowing users to install low-profile cards such as additional NICs, storage controllers, or even mobile GPUs through adapters. While the slot runs at x8 electrically, it can mechanically accommodate a x16-sized card, offering some flexibility in component choice.

However, users will need to consider power and thermal requirements carefully, given the limited space and airflow in the chassis. Overall, the MS-A2 offers a strong set of external connection options that match its intended role as a workstation-class device in a small form factor.

Minisforum MS-A2 Review – Design, Cooling and Power Consumption

The Minisforum MS-A2 maintains a compact footprint at 196 × 189 × 48 mm, but compared to typical mini PCs, it leans toward a small form factor workstation design rather than an ultra-portable device. Accessing the internals is straightforward thanks to a tool-less design: a single latch at the rear releases the chassis cover, making upgrades and maintenance simple. Ventilation is placed around all sides and across the base, maximizing airflow within the tight internal layout. Although densely packed, the internal component arrangement is relatively clean and accessible given the system’s size constraints.

Cooling inside the MS-A2 is split between two fans: a 12V fan for the CPU, which uses a heat pipe and fin arrangement, and a separate 5V fan cooling the storage area and 10GbE networking controller.

Minisforum has improved fan placement over the earlier MS-01 model, aiming to deliver better cooling to both the processor and critical components without introducing excessive noise.

During testing, the CPU temperatures at idle remained around 31–32°C, rising to approximately 50–52°C under sustained heavy load, including simultaneous 10GbE network activity and storage operations. SSD temperatures were also well-controlled, aided by direct airflow across the M.2 slots.

Power delivery for the MS-A2 comes through an external 240W power brick, rather than an internal PSU.

This design choice saves internal space but results in a relatively bulky external adapter. In idle conditions, the system drew between 23W and 26W, depending on network activity.

During maximum CPU load under PCMark and 3DMark testing, power consumption peaked at 129W.

Average system operation under moderate workloads saw consumption range between 60W and 80W. These figures suggest a reasonably efficient platform considering the CPU core count and networking capabilities, though users expecting true low-power behavior typical of smaller mini PCs should adjust their expectations accordingly.

Noise levels from the MS-A2 stayed moderate during most activities. Fan noise measured around 36–38 dB under light loads and rose to about 41–43 dB under heavy CPU and network utilization. This places the MS-A2 in a middle ground: quieter than larger workstations but more audible than simpler fanless mini PCs.

Overall, Minisforum’s cooling approach is effective for a compact workstation, balancing thermal performance and acoustic levels without the need for more aggressive—and louder—cooling solutions.

Minisforum MS-A2 Review – Performance Testing

In general usage and synthetic benchmarking, the Minisforum MS-A2 delivered performance levels in line with expectations for a device built around high-end mobile Ryzen processors. PCMark 10 returned an overall score of 6494, with strong showings in productivity (10,353 points) and essentials tasks (11,186 points). Applications like web browsing, document editing, and video conferencing performed without issue, backed by high single-thread and multi-thread responsiveness from the Ryzen 9 9955HX. The MS-A2 consistently handled multitasking loads involving office work, streaming, and background processes without noticeable slowdown.

For more demanding tasks, the MS-A2 remained competitive but showed the limitations of relying solely on integrated graphics. Digital content creation, including tasks like photo editing and light video editing, produced a PCMark 10 sub-score of 6418, which is respectable but not exceptional. 3DMark testing confirmed the Radeon 610M’s limited capabilities for 3D rendering and gaming workloads, achieving a Steel Nomad Light score of 605. These results reaffirm that while the MS-A2 is well-suited to workstation and productivity tasks, it is not designed for gaming or heavy graphical processing without an external GPU.

CPU-centric benchmarks demonstrated the strength of the Ryzen 9 9955HX. In the 3DMark CPU Profile test, the MS-A2 achieved 10,208 points at maximum threads and 9,879 at 16 threads, with a respectable 1,235 points in single-thread performance.

These scores reflect excellent multi-threaded processing capabilities, making the MS-A2 a solid choice for parallelized workloads such as software compilation, virtualization, and data analysis. Across extended testing sessions, thermal throttling was minimal, and the system maintained consistent performance without significant drops under sustained load.

Storage performance varied depending on the drive slot used, but generally provided strong results. Read speeds were consistently high, reaching 5.5 GB/s in AJA testing and peaking at 7.3 GB/s in CrystalDiskMark. However, write speeds showed more inconsistency across different test runs, sometimes peaking near 4 GB/s but with occasional dips depending on the benchmarking tool and conditions. While read performance makes the MS-A2 well suited for workloads involving frequent large file access, users planning heavy write-intensive tasks may want to further validate storage behavior based on their specific needs.

Minisforum MS-A2 or the Minisforum MS-01 PC?

While the Minisforum MS-A2 and MS-01 share a compact workstation focus, they are built around notably different platforms and priorities. The MS-01 uses Intel’s 12th and 13th Gen Core H-series processors, with options ranging from the Core i5-12600H to the Core i9-13900H, alongside Intel Iris Xe integrated graphics. It supports up to 64GB of DDR5 memory at 5200MHz and offers storage flexibility with up to three M.2 SSD slots. Crucially, the MS-01 features two USB4 ports capable of 40Gbps speeds and supports external GPU connectivity, along with dual 2.5GbE RJ45 ports and dual 10GbE SFP+ ports for network-heavy environments.

In contrast, the MS-A2 leverages AMD’s Ryzen 9 9955HX or 7945HX CPUs, offering more cores (16 cores and 32 threads) compared to the MS-01’s maximum of 14 cores and 20 threads. It also supports up to 96GB of DDR5 memory and includes three PCIe 4.0 NVMe slots, but lacks USB4 or Thunderbolt connectivity. Instead, the MS-A2 leans on internal expandability with a full PCIe 4.0 x8 slot and places a stronger emphasis on internal compute performance rather than external device bandwidth. Users needing the fastest possible external drive support or lighter CPU performance may prefer the MS-01, while those requiring maximum multi-threaded processing power and internal storage scalability will find the MS-A2 better suited to their needs.

Minisforum MS-A2 Review – Conclusion and Verdict

The Minisforum MS-A2 offers a significant amount of performance and expandability within a relatively compact design, but it is important to recognize exactly who this system is built for. Users needing strong CPU performance for workloads like virtualization, software development, database management, or network-attached storage will find a lot to like here. The Ryzen 9 9955HX and 7945HX options deliver high core and thread counts rarely seen in mini PCs, supported by fast DDR5 memory and ample M.2 storage options. Dual 10GbE SFP+ ports and PCIe 4.0 expandability add further flexibility for networked environments or specialized hardware configurations. However, the absence of USB4 or Thunderbolt support means the MS-A2 will not suit workflows heavily reliant on high-speed external devices. Storage write performance inconsistencies observed during testing may also warrant further validation depending on the intended workload.

Compared to the MS-01, the MS-A2 trades away some external connectivity and general-purpose flexibility in favor of raw compute power and internal upgrade potential. It does not replace the MS-01, nor is it a direct successor to the MS-A1—it instead sits alongside these models, offering an AMD-based alternative better suited for users prioritizing workstation performance over consumer-grade convenience. At a price range of $639 to $839 depending on the CPU, the MS-A2 is not inexpensive, and users must weigh its strengths against what they actually need. If maximum internal power, heavy multitasking, and network scalability are the priorities, the MS-A2 justifies its cost. If external GPU use, lighter workloads, or lower noise are the focus, other options—including the MS-01—might make more sense. Overall, the MS-A2 fills an important niche in Minisforum’s lineup, provided buyers approach it with the right expectations.

WE LOVE COFFEE

Depuis quelques semaines, Synology prend un virage qui en déroute plus d’un. Tout d’abord, le fabricant limite désormais la compatibilité de ses NAS de la série “Plus” aux seuls disques durs et SSD Synology. Résultat : la DSx25+ est fermée à l’écosystème tiers. Seuls les disques Synology sont compatibles avec la gamme DSx25+. À ce jour, aucun fabricant de disques n’a obtenu de certification. Ce choix stratégique, associé à un DS925+ peu convaincant, pousse une partie de la communauté à envisager des alternatives sérieuses.

Dans ce contexte, nombreux sont ceux qui m’ont demandé quelle alternative pour remplacer un NAS Synology ?

Alternative à Synology

Avant toute chose, rappelons que la majorité des fabricants de NAS sont basés en Chine et à Taïwan. Un événement très important approche : le Computex. Les fabricants y dévoilent traditionnellement leurs nouveautés.

Comparatif meilleurs NAS en 2025

Si vous envisagez de quitter Synology, vous devez être prêt à faire une croix sur DSM, avec son interface et ses applications.

Quels fabricants sur le marché ?

Après Synology, on pense tout de suite à QNAP qui joue au coude à coude avec le fabricant historique. Ensuite, il y a bien sûr Asustor, mais aussi TerraMaster, Ugreen qui vient fraichement de débarquer. Après, le DIY (fait maison) a le vent en poupe en ce moment.

Mon choix : QNAP TS-464

Si je devais aujourd’hui remplacer mon NAS Synology, ce serait sans hésiter par le QNAP TS-464. Ce boitier dispose de 4 emplacements pour disques durs 3,5″ & SSD 2,5″, d’une architecture performante et d’une connectique riche.

Intérieur du NAS

Ce NAS est construit autour d’un processeur Quad Core Intel Celeron N5105 cadencé à 2 GHz (mode Burst jusqu’à 2,9 GHz). Il dispose de 8 Go de RAM extensibles jusqu’à 16 Go. Cette architecture fait de ce NAS un produit performant et économe en énergie. Il sera à l’aise avec les applications multimédias (Plex, Jellyfin…), Docker ou encore la virtualisation de machines Linux ou Windows.

Toujours à l’intérieur, le TS-464 possède 2 emplacements NVMe M.2 pour des SSD ultra-rapides.

Disque dur et SSD

Sur la question de la compatibilité, le TS-464 accepte de nombreux disques durs et SSD. Personnellement, je recommande les WD Red Plus, une valeur sûre.

Pour les SSD, j’apprécie également les WD Red SA500/SN700, mais aussi Samsung Plus/Pro ou encore les Crucial MX500. Ils fonctionnent tous très bien dans les NAS QNAP.

Interface de connexion

La connectique est également très riche :

• 2 ports USB 2.0 (arrière) ;
• 2 ports USB 3.2 Gen 2 (dont 1 en façade) ;
• 1 sortie HDMI 2.0 ;
• 2 ports réseau 2,5 Gb/s ;
• 1 slot PCIe Gen 3 x2 pour ajouter une carte 10 Gb/s ou des ports supplémentaires.

Oui, cela peut surprendre si vous ne connaissez que les NAS Synology.

Test du NAS QNAP TS-464

QTS

Le système embarqué dans les NAS QNAP se nomme QTS. C’est un système optimisé pour le stockage en réseau avec une interface moderne et complète. Comme avec DSM, il est possible d’installer de nombreuses applications : virtualisation, sauvegarde, multimédia, etc. Il existe également un catalogue d’application alternatif, MyQNAP.org qui proposent plusieurs centaines d’applications.

Même s’il est un peu plus technique que DSM, QTS est vraiment très puissant une fois qu’on le maîtrise, avec des possibilités supérieures.

QuTS Hero

QNAP propose un second système pour certains de ses NAS, dont le TS-464 : QuTS Hero. Il s’agit sensiblement de la même chose que QTS, mais axé sécurité et performances grâce notamment au système de fichiers ZFS nativement supporté ici.

Support

QNAP dispose d’une équipe en France, offrant un support en français pour les particuliers et les professionnels. De mon point de vue, c’est vraiment un atout. Même si l’IA commence à révolutionner le support technique, la présence humaine reste encore nécessaire. Aussi, vous pouvez compter sur le Forum des NAS avec sa communauté active et engagée.

Prix

À son lancement, le TS-464 coûtait environ 710 €, un tarif très élevé pour l’époque. Aujourd’hui, il est disponible autour de 630 €, ce qui reste un investissement, mais raisonnable au regard de ses prestations.

En synthèse

Si vous cherchez une alternative fiable, puissante et évolutive à un Synology 4 baies, le QNAP TS-464 est un excellent choix. Il demande peut-être un peu plus temps dans sa prise en main, mais les possibilités offertes par ce NAS sont nettement supérieures.

La nouvelle politique mise en place par Synology avec la série de NAS DSx25+ apporte beaucoup de confusion. Dans les commentaires, vous êtes nombreux à poser des questions — parfois en faisant quelques amalgames. Il faut reconnaître que la communication de Synology n’a pas été très claire sur ce sujet. Ayant un NAS DS925+ en test depuis plusieurs jours, je vais tenter de vous apporter quelques informations complémentaires basées sur mes propres tests.

Compatibilité disque dur et SSD

Avec la nouvelle série DSx25+, Synology a fait le choix de restreindre encore davantage la compatibilité des disques durs et SSD pour ses NAS. À l’heure où j’écris ces lignes, seuls les disques durs et SSD Synology sont officiellement compatibles.

Disposant d’un DS925+, j’ai effectué plusieurs essais avec différents disques et SSD. Voici ce qu’il en ressort…

Migration de disque dur

Fin 2023, j’ai remplacé mon NAS Synology DS920+ et, au passage, j’ai changé l’un des disques durs : un WD Red 4 To. Pour rappel, ce disque est spécialement conçu pour les NAS. Il est compatible avec l’ensemble des précédents NAS Synology, ainsi que chez les autres fabricants (Qnap, Asustor, TerraMaster, etc.).

Le disque, que je n’avais pas reformaté, a été inséré dans le DS925+. Dès le démarrage, le NAS le détecte correctement et propose une migration depuis l’ancien système. Une bonne nouvelle…

Après la migration et le redémarrage du NAS, les données sont parfaitement accessibles. Cependant, en consultant le Gestionnaire de stockage, des avertissements apparaissent :

Voici ce qu’indique DSM : « Ce groupe de stockage contient un ou plusieurs disques migrés. Ces disques peuvent affecter la fiabilité et la stabilité du système et doivent être remplacés immédiatement. Consulter les Infos sur le disque ci-dessous pour identifier les disques migrés. Veillez à sauvegarder vos données, puis supprimez ce groupe de stockage. Créez un nouveau stockage après avoir remplacé les disques par des disques compatibles ». Vous aurez noté également l’information en bas à droite en rouge « Migré depuis un autre système« .

La bonne nouvelle, c’est que tout fonctionne… sauf que l’on a un message d’avertissement. Synology explique qu’il faut le changer rapidement.

Nouvelle installation avec un disque dur

J’ai ensuite procédé à une réinitialisation complète du NAS, tout en conservant le même disque WD Red 4 To. Cette fois-ci, impossible de créer un volume de stockage. Oui, vous avez bien lu : blocage complet par le système.

DSM indique que « Aucun des disques inutilisés de votre Synology NAS ne répond aux exigences de disque ». Si je clique sur plus de détails, un message en rouge m’informe : « Ce disque ne figure pas sur la liste de compatibilité des produits Synology« . Impossible d’aller plus loin…

J’avoue avoir été surpris par cette interruption brutale de la part de Synology. Pour information, j’ai également tenté l’expérience avec un Seagate IronWolf Pro : le comportement est exactement le même.

Nouvelle installation avec un SDD

Étonnamment, le comportement est différent avec un SSD. Je possède un WD Red SA500, un modèle conçu pour des environnements RAID fonctionnant 24h/24 et 7j/7. Encore récemment, il était compatible avec tous les NAS Synology lui aussi.

Avec ce SSD, la création du groupe de stockage est possible. Synology semble estimer qu’un SSD répond mieux à certains critères de qualité (probablement en termes de vitesse de lecture/écriture) qu’un disque mécanique.

DSM autorise donc la création du volume de données, mais… de nombreux avertissements sont présents (notifications système, avertissement dans le Widget…) et notamment dans Gestionnaire de stockage :

Voici le message : « Ce groupe de stockage contient un ou plusieurs disques non vérifiés. L’utilisation de disques non vérifiés peut affecter la fiabilité et la stabilité du système. Vous pouvez vérifier les Infos sur le disque pour identifier les disques non vérifiés. Veillez à sauvegarder les données de ce groupe de stockage avant de le supprimer. Remplacez ensuite les disques non vérifiés et créez un nouveau groupe de stockage ».

Là aussi, Synology explique qu’il faut le changer rapidement.

En synthèse

Depuis quelques années, Synology renforce progressivement le contrôle sur l’écosystème matériel de ses NAS. Avec la série DSx25+, cette politique devient encore plus stricte : seuls les disques Synology sont officiellement supportés.

Avec un disque dur non Synology (WD Red, Seagate IronWolf…) :

Migration possible si le disque provient d’un ancien NAS Synology

Impossible de créer un nouveau volume/groupe de stockage

Avec un SSD non Synology (WD Red SA500 par exemple) :

Création d’un nouveau volume/groupe de stockage possible

Présence d’avertissements sur la compatibilité et les risques encourus

Si vous envisagez d’acheter un nouveau NAS Synology de cette gamme, il faudra impérativement intégrer dans votre budget l’achat de disques durs ou SSD Synology, sous peine de rencontrer des limitations.

À noter : pour ceux qui souhaitent savoir si le script 007revad fonctionne (afin de rendre éligibles les disques durs et SSD tiers) : la réponse est oui.

UniFi UNAS Pro: 6 Months On — A Measured Look at Ubiquiti’s First NAS

Six months since its public release in October 2024, the UniFi UNAS Pro has matured modestly but meaningfully. Initially positioned as an affordable $499, 7-bay NAS with integrated 10GbE and 1GbE networking, its appeal centered largely around seamless integration into UniFi environments and simple turnkey deployment. The first three months revealed a system that delivered on core promises without overselling itself, providing reliable basic storage with intuitive setup, minimal friction during deployment, and straightforward SMB file sharing. However, its limitations in areas such as feature breadth, expandability, and advanced administrative control left some early adopters questioning whether the device was ready to serve as a primary NAS solution.

UniFi UNAS Pro 6 Months Later – The TL;DR

Ubiquiti’s UniFi UNAS Pro has seen steady but conservative development since its launch in October 2024. At $499, it’s an affordable 7-bay NAS with 10GbE that integrates well within UniFi environments, but it launched with limited features and notable gaps. Over six months, some user-requested improvements have been delivered—such as RAID 6 support, expanded cloud backup options (Dropbox, OneDrive), admin control over user backups, and improved file sharing responsiveness. However, key omissions remain: no iSCSI support, no UniFi Protect integration, no containerization, no fan or power schedule controls, and occasional performance or file handling issues. It’s best suited as a supplementary NAS for existing UniFi networks rather than a full-featured standalone solution. Ubiquiti appears focused on stability and foundational updates, but major feature enhancements or new models have yet to appear. HERE are the most notable changes that have happened in the last 6 Months:

• Added support for RAID 6, hot spare migration, and Time Machine backups via Shared Drives.

• Enabled OneDrive and Dropbox as new cloud backup destinations.

• Introduced File Activity tracking and a Task Center for monitoring ongoing operations.

• Console owners can now manage and back up other users’ drives.

• Added SIEM server integration, SNMP configuration, and support for .exe execution via SMB.

• Users can now toggle Link Sharing and configure release channels per app.

• Support file generation now available for diagnostics.

• Improved setup, storage initialization, drive transfers, and local admin creation flows.

• Enhanced system performance, search speed, and responsiveness across the UI.

• File browsing, sharing, and backup/restore processes made smoother and more reliable.

• Boosted storage mounting and format resiliency, RAID resync handling, and external storage support.

• Improved reporting for storage health, system logs, and overall stability—especially with SSDs and encryption.

• Better SFP speed detection and more stable SMB file operations.

• Resolved issues with folder renaming, failed downloads, backup restore login errors, infinite loading on drive.ui.com, toast notification bugs, and destination switching during backups.

One of the more frequently cited early limitations was the lack of support for advanced RAID configurations and flexible storage management. At launch, users were restricted to basic options like RAID 1, 5, and a variant of RAID 10, with no ability to create multiple independent storage pools. This particularly limited users who wanted to separate SSDs for high-speed cache or hot data from HDDs used for cold or archival storage.

Three months after launch, UniFi began rolling out RAID 6 support—a heavily requested feature—and its integration was further refined by the six-month mark. Notably, users who had initially set up a RAID 5 with a hot spare could now migrate more smoothly to RAID 6 without complete data loss, provided certain steps were followed. While the system still lacks support for custom pool creation or tiered storage strategies, the RAID 6 addition is a clear example of Ubiquiti incorporating community feedback into its development roadmap.

Early adopters also flagged the limited backup options as a major downside, especially for offsite or cloud-based protection. Initially, users were confined to backups via SMB or to another UNAS unit, with Google Drive being the only available cloud service. This created friction for users looking to consolidate cloud storage or use existing platforms.

By the six-month update, support had been added for Dropbox and Microsoft OneDrive, expanding options and bringing the system more in line with mainstream NAS offerings. While other major providers like Amazon S3 or Backblaze B2 remain unsupported, the progress demonstrates ongoing development—even if somewhat slower than expected.

Administrative oversight and user management were similarly underdeveloped at launch. The inability for a super admin to manage, view, or initiate backups on user-specific drives was seen as a major gap in functionality. This was especially problematic in small businesses or households where centralized management is essential. At the six-month mark, UniFi addressed this by enabling admins to directly control user backup routines, offering a more appropriate level of oversight. Though expected in any multi-user NAS environment, this feature only arrived after considerable community pressure, reflecting a reactive—rather than proactive—development pattern.

Performance concerns also became more visible in real-world use. While general file transfers over SMB were stable for most users, large-volume or high-frequency data movements revealed issues. Users reported memory leaks, skipped files, permission errors, and signs of system instability during multi-terabyte migrations. One user described persistent problems during direct NAS-to-NAS SMB transfers, citing missing files and log entries showing out-of-memory warnings. While UniFi has issued multiple patches in response, these issues underline the system’s current limits as a high-performance data mover. Paired with its ARM-based CPU and fixed RAM, the UNAS Pro may not be ideal for workflows involving large file sets or deep nested directories with complex characters.

Quality-of-life improvements have also slowly emerged. File and folder sharing via the GUI is now more responsive, addressing early complaints that changes wouldn’t reflect until refreshing the browser or navigating away. A newly added file activity monitor provides more transparency by displaying changes and access logs on a folder-by-folder basis—a helpful addition for environments that require audit trails. Time Machine support has also been added for macOS users, allowing backups over SMB directly to the device. Additionally, executable files (.exe) now correctly run from network shares, resolving an earlier issue where files appeared to launch but did not actually execute on the system.

Despite hardware parity with UniFi’s UNVR line, the UNAS Pro still does not support UniFi Protect, Ubiquiti’s NVR platform. Although this was never advertised, its omission has disappointed users who hoped to consolidate storage and surveillance into a single device. Likewise, containerization remains absent. Users cannot deploy Docker or LXC-based services directly on the NAS. While the system is positioned more as a basic storage server than a full-featured app platform like Synology or QNAP, even lightweight container support would help bridge the gap in hybrid setups, reducing dependency on external devices for running supplemental services.

Several other features considered standard in competing NAS platforms are still missing. These include iSCSI target support, which allows for block-level storage mapping—a commonly requested enterprise feature that remains unaddressed despite repeated user requests. Scheduled power controls and Ethernet port management are also absent, limiting users’ ability to implement air-gapped operation cycles or optimize network behavior during off-hours.

Additionally, fan control settings are locked, leaving users with no way to adjust thermal behavior. System temperatures frequently hover in the 60–70°C range even during idle states, which some consider concerning. Whether due to poor fan curve logic or unreliable sensor reporting, the lack of manual override remains a drawback.

Another issue affecting a minority of users involves file download errors on mobile devices, particularly iPhones using Safari. Files would only partially download—such as halved images or incomplete audio/video files. The problem was isolated to Safari and resolved by switching to Chrome, but it exposed weaknesses in browser compatibility. Additionally, several systems erroneously report uptime durations exceeding 20,000 days—an obvious bug that, while harmless, illustrates rough edges still present in the software’s reporting logic.

As of April 2025, no additional NAS models have been added to the UniFi lineup. There is still only a single variant of the UNAS Pro, and no indications of rackmount, multi-unit, or lower-tier models have been announced. This suggests Ubiquiti is still treating this device as a pilot platform. The pace of development has been steady, with multiple small improvements and responses to community feedback, but foundational gaps remain. For users who need secure, reliable bulk storage within an existing UniFi network, the UNAS Pro is increasingly serviceable.

However, for broader use cases, it still lacks the depth, flexibility, and robustness of more established NAS vendors. Defintely a device with a long term plan, but it is not in a big hurry to stretch it’s muscles quite yet – but at $499, it has an exceptionally low bar for entry price wise for what you are getting!

WE LOVE COFFEE

Synology vient de dévoiler officiellement son prochain NAS : le DS925+. Il fait déjà beaucoup parler de lui sur les réseaux. Même s’il n’est toujours pas commercialisé, ses spécifications sont d’ores et déjà connues. Vous avez été nombreux à nous solliciter pour savoir ce qu’apporte ce nouveau modèle face à son prédécesseur le DS923+. Nous vous proposons donc un comparatif clair et détaillé basé sur les données constructeurs pour vous aider à y voir plus clair.

DS925+ vs DS923+

Les NAS DS925+ et DS923+ sont des boîtiers plutôt haut de gamme chez Synology. Ils proposent chacun 4 emplacements en façade pour des disques durs ou SSD, ainsi que 2 emplacements SSD NVMe sous le NAS (pour le cache ou comme volume de stockage).

Il est également possible d’y connecter une unité d’expansion à 5 baies (DX525), permettant d’atteindre un total de 9 disques. Cette nouvelle unité externe utilise un port USB Type-C.

Processeur

Synology poursuit l’intégration de processeurs AMD Ryzen Embedded dans ses NAS. Le DS925+ embarque désormais un Ryzen V1500B Quad Core cadencé à 2,2 GHz, en remplacement du Ryzen R1600 Dual Core du DS923+.

Ce changement apporte une légère amélioration des performances, notamment en multitâche. Cependant, aucun des 2 modèles ne dispose d’un iGPU (processeur graphique intégré), ce qui limite leur capacité à faire du transcodage vidéo matériel… un point important pour les usages multimédia.

Mémoire ECC

La mémoire vive n’évolue pas entre les 2 modèle. On reste sur 4 Go en DDR4  ECC (Error-Correcting Code ou en français, code correcteur d’erreurs). La mémoire ECC est plus chère, mais elle apporte une certain stabilité. Elle est rarement conseillée dans les NAS, sauf lorsque le système utilise le système de fichiers ZFS.

Les 2 modèles intègrent 4 Go de mémoire DDR4 ECC, extensible jusqu’à 32 Go. C’est vraiment peu pour ce type de produit. La mémoire ECC (Error-Correcting Code) améliore la stabilité et la fiabilité, même si elle n’est pas indispensable dans un NAS non basé sur ZFS.

Connectique

Le DS925+ gagne 1 port USB 3.0 Type-C et 2 ports réseau 2,5 Gb/s. C’est la grande nouveauté de la gamme DSx25+, trop longtemps attendu.
En revanche, il perd l’emplacement pour la carte réseau 10 Gb/s (en option sur le DS923+). Ce dernier permettait d’atteindre selon le fabricant 1180 Mo/s en lecture et 772 Mo/s en écriture séquentielle, avec des SSD NVMe.

Limitation volontaire

Le principal point de friction reste la politique de compatibilité imposée par Synology. Le fabricant restreint l’usage aux disques durs et SSD certifiés. À ce jour, aucun disque n’est officiellement validé pour la série DSx25+, ce qui pourrait poser problème à court terme pour les acheteurs souhaitant utiliser leurs propres disques.

Tableau comparatif DS925+ vs DS923+

En synthèse

Le DS925+ s’inscrit dans la continuité du DS923+ avec quelques améliorations : un processeur plus costaud, des ports réseau 2,5 Gb/s et une connectique légèrement enrichie. Cependant, la suppression de l’emplacement pour carte 10 Gb/s et la politique de disques certifiés viennent tempérer cet enthousiasme.

Pour les utilisateurs ayant besoin de plus de baies, le DS1522+ reste une alternative intéressante avec ses 5 baies natives et la possibilité d’ajouter jusqu’à deux unités DX517. En revanche, son prix est plus élevé, aux alentours de 757 €.

Synology vs UGREEN NAS – Which One Deserves Your Money and Your Data?

In the evolving world of network-attached storage (NAS), users in 2025 are faced with a broader range of choices than ever before. Among the most discussed options in both professional and enthusiast communities are Synology and UGREEN. Synology has been a mainstay in the industry for over two decades, known for its reliable software, long-term support, and deeply integrated ecosystem. UGREEN, by contrast, is a relative newcomer to the NAS market in the West, but has quickly established itself as a serious contender by offering competitive hardware and pricing. Originally known for consumer tech peripherals, UGREEN has leveraged its manufacturing experience and market agility to carve out space in an area traditionally dominated by established NAS brands.

This comparison aims to provide a clear, unbiased overview of both brands, structured across several key categories: hardware capabilities, storage flexibility, software ecosystem, security infrastructure, pricing strategy, and overall value proposition. While some buyers may lean toward a brand due to legacy, others are driven by performance-per-dollar, or openness to customization. It’s important to understand that neither brand is objectively “better” in all respects. Instead, each appeals to different user priorities. What follows is a breakdown of how Synology and UGREEN compare across the board, giving potential buyers the tools they need to make a decision that aligns with their use case, technical comfort level, and long-term plans.

Synology vs UGREEN NAS Hardware Compared 

Synology’s hardware lineup spans everything from small 1-bay entry-level NAS units to rackmount enterprise-class systems with dual controllers. With approximately 15–25 models available at any given time, the variety on offer is extensive. This allows users to choose systems that align closely with their needs—whether that’s for simple backups, media streaming, virtualization, or business-critical data management. However, despite the breadth of its portfolio, Synology’s consumer and SMB offerings are frequently criticized for underpowered processors and limited upgrade paths. Many of their mid-tier models still rely on AMD Embedded or lower-end Intel chips, and memory configurations are often modest compared to similarly priced alternatives. PCIe expansion, 10GbE networking, and true Flash storage support are typically reserved for only the highest-tier devices.

UGREEN, on the other hand, has entered the NAS space with a clear emphasis on hardware strength. Their NASync series—although more limited in model variety—delivers high-performance components out of the box. Even in models priced around $1,100 to $1,200 USD, UGREEN includes features like Intel i5 processors, 16GB of DDR5 RAM, dual 10GbE ports, USB4, SD card slots, and Thunderbolt connectivity. Most of specifications are generally only found in Synology’s XS or SA series, which can cost double or triple the price. In terms of build quality, UGREEN’s enclosures also lean toward a more robust, enterprise-like design with better thermal management and port selection. While they may not yet offer the same portfolio depth or high-end rackmount solutions, the raw hardware value they deliver—especially for power users and media professionals—is difficult to overlook.

Synology DSM vs UGREEN UGOS NAS Software & Services

Storage features and flexibility represent one of the most contested areas between the two brands. Synology has developed a very feature-rich storage management system over the years, offering support for RAID configurations, Btrfs and EXT4 file systems, fast RAID rebuilds, advanced iSCSI LUN management, and deep integration with backup and synchronization tools.

File Services	SMB/NFS/AFP/WebDAV	Supported	Supported (AFP not confirmed)	Core protocols available
	iSCSI Support	Native iSCSI manager	Not currently supported	Important for VM/block-level storage
RAID & Storage	RAID 0/1/5/6/10, SHR	SHR and traditional RAID	Traditional RAID 0/1/5/6/10	No SHR support in UGREEN
	Snapshots	Btrfs-based with GUI versioning	Btrfs-based snapshots	Comparable snapshot system
	Deduplication	Btrfs-based	Planned, not available yet	UGREEN roadmap feature
	Encryption	Volume/folder/drive-level + WORM	No integrated encryption	Major security difference
	SSD Caching	GUI-managed	CLI-managed only (UI planned)	Limited interface currently

Their platform also supports drive pooling, storage tiering (in some models), and robust snapshot capabilities. Expansion options are a strong point too, with a range of proprietary expansion units that allow users to scale storage well beyond the original NAS chassis. These are bolstered by robust utilities in DSM that help manage redundancy, performance, and data recovery, all while maintaining consistency across the ecosystem.

However, Synology’s 2025 policy shift around hard drive compatibility introduces a significant caveat. Newer devices now strictly require Synology-branded drives for both HDD and SSD roles, including caching and storage pools. This effectively locks users into the Synology ecosystem and limits the ability to use commonly available alternatives from WD, Seagate, Samsung, and others. Availability issues in some regions further complicate this approach.

UGREEN, conversely, supports a far more open system—allowing users to populate their NAS devices with nearly any 2.5″, 3.5″, or NVMe drive on the market. With support for drives up to 24TB and Gen 4 NVMe speeds reaching 6,000–7,000 MB/s, UGREEN offers unmatched flexibility in storage media. However, their systems currently lack support for iSCSI and official expansion units, which could be a limitation for more advanced storage scenarios.

Software Comparison

Synology’s DiskStation Manager (DSM) is widely regarded as one of the most refined and mature NAS operating systems in the market. Backed by over two decades of development, DSM offers a wide range of first-party apps covering backup, multimedia, productivity, collaboration, and virtualization.

Tools like Synology Drive, Active Backup for Business, and Synology Photos provide enterprise-grade capabilities in a consumer-friendly package. The platform also integrates with cloud services like Office 365 and Google Workspace, and includes support for SANs, VMs, containers, and cloud sync. Importantly, most of these apps are license-free, representing significant value over time. The application center in DSM is extensive, and Synology’s desktop and mobile client tools are similarly well-developed.

Category	Feature	Synology	UGREEN NASync (DXP Series)	Notes
Core OS	OS	DSM (DiskStation Manager)	UGOS	Synology has a mature, polished UI
	Mobile Apps	Multiple DS apps across iOS/Android	One core management app + FireTV/Google Home apps	Broader app suite on Synology
Virtualization & Containers	Virtual Machines	Virtual Machine Manager	Dedicated VM app	Both platforms now offer VMs
	Docker Support	GUI + Docker CLI	Portainer + Docker CLI	Equal container support
	GPU Passthrough	Not available	Not supported	Neither platform offers this
AI & Surveillance	AI Services	Facial/people detection on DVA NAS	Advanced AI model recognition (Photo AI)	UGREEN offers more AI model types
	Surveillance Suite	Surveillance Station (native)	No native system (use Frigate, MotionEye via Docker)	Docker-based alternative
Media & Streaming	Plex Media Server	Native app support	Docker-only installation	Equal in function
	Jellyfin	Docker/homebrew only	Native app available	More flexible on UGREEN
	Video App	Video Station is EOL	Native video player app	UGREEN actively supports this
Backup & Sync	Backup Solutions	Hyper Backup, Active Backup Suite	Rsync, SMB, Cloud Backup, USB	GUI edge to Synology

Remote Access	DDNS + Tunnel	QuickConnect	UGREEN-hosted tunnel system	Functional equivalents
App Ecosystem	App Center	Extensive with many native packages	Real app center, but much smaller	Synology has a broader catalog
	Package Manager	synopkg	APT + Docker

UGREEN’s UGOS, by contrast, is still in its early stages—at least in the Western market—but has made notable progress. Built on a Linux-based open-source foundation, UGOS offers a modern UI and essential features like RAID management, Docker support, virtualization, remote access, and media streaming. The system is responsive and user-friendly, with most core NAS functions well-covered.

UGREEN’s App Center is less populated but growing, and the brand has made particular strides in AI-driven features—particularly in its photo application, which allows customizable object and face recognition with trainable AI modules. While still lacking some advanced enterprise features like Synology’s iSCSI or SAN support, UGOS is impressive for a brand with only a few years of development. Notably, UGREEN also supports the installation of third-party operating systems like TrueNAS or OpenMediaVault, appealing to users who want full control over their NAS.

Synology vs UGREEN NAS – Security 

When it comes to security, Synology’s long-standing reputation and infrastructure give it a distinct advantage. Over the years, the company has invested heavily in platform hardening, threat detection, and vulnerability response. The built-in Security Advisor not only scans for malware and viruses but also detects weak passwords, outdated software, open ports, and potentially exploitable system configurations. Synology participates in vulnerability disclosure programs, works with penetration testers, and maintains a public-facing security advisory database. They’ve even implemented a bounty system to reward ethical hackers for reporting vulnerabilities. These layers of proactive defense have earned Synology its reputation as one of the most secure NAS platforms in the world.

UGREEN has not experienced any public security incidents as of 2025, but its shorter time in the market means less historical data on its resilience. Their systems now include two-factor authentication and basic malware scanning, but currently lack the more comprehensive vulnerability detection tools that Synology provides. The security advisor in UGOS focuses primarily on active threats like viruses rather than system-level hardening.

That said, UGREEN has been responsive to user feedback and appears committed to improving its security infrastructure. For experienced users who follow best practices and secure their networks effectively, this may not be a deal-breaker. However, for enterprise users or those deploying systems in high-risk environments, Synology’s mature security ecosystem provides more peace of mind.

Remote Access	DDNS + Tunnel	QuickConnect	UGREEN-hosted tunnel system	Functional equivalents
Security & Access	Security Advisor	Ransomware, audit, malware, system hardening	Basic malware scanning only	Synology offers deeper protections
	VPN Server	Native UI for OpenVPN, L2TP, PPTP	Docker-based VPNs (WireGuard, OpenVPN)	Manual setup on UGREEN
	SSL Certificates	Let’s Encrypt + GUI	Let’s Encrypt via Web UI	Parity here
	2FA Support	App-based 2FA	TOTP/Web 2FA	Both support 2FA login

Synology vs UGREEN NAS – Pricing and Value 

Pricing is one of the most decisive factors favoring UGREEN in 2025. The brand offers high-performance hardware at price points that undercut Synology by a substantial margin. An 8-bay UGREEN NAS with an Intel i5 CPU, 16GB DDR5 RAM, dual 10GbE, and Thunderbolt can be purchased for roughly $1,200-1300 (store depending). A Synology unit with similar specs would require jumping to the DS1823xs+ or even the SA series—devices that retail between $1,800 and $3,000 depending on configuration and region. This gap in price-performance makes UGREEN especially appealing to users who want modern hardware for tasks like 4K video editing, large-scale backups, or AI analytics but can’t justify enterprise-level spending.

Synology’s pricing strategy is rooted more in its software and long-term value. While the upfront cost may be higher, the investment is offset by an integrated ecosystem, professional-grade applications, and superior long-term support. For some buyers, particularly businesses and advanced home users who need software stability and vendor accountability, the price premium is justified. However, for price-sensitive consumers, hobbyists, or those comfortable managing their own systems, UGREEN’s value proposition is hard to beat. It’s also worth noting that UGREEN’s openness to third-party operating systems can further extend the device’s utility without adding cost, whereas Synology systems are heavily locked into their proprietary software environment. Here is a comparison of the Synology DS1823xs+ and the UGREEN DXP8800 PLUS NAS. Around $449 difference, but also the general level of the hardware inside and externally is technically higher on the UGREEN system. That said, the Synology system software does a huge amount with it’s software, keeping things super efficient. So, now let’s discuss storage and the respective software that both of these platforms offer to house and protect your data.

Synology vs UGREEN NAS – Verdict & Conclusion

Choosing between Synology and UGREEN in 2025 ultimately comes down to what matters most to the user. Synology is the more mature and refined platform, with a rock-solid software ecosystem, strong security credentials, and long-standing industry credibility. It is ideal for users who want a fully integrated solution with minimal tinkering, extensive app support, and professional-grade backup, synchronization, and collaboration tools. However, the brand’s increasing restrictions on drive compatibility, slower hardware updates, and higher prices may discourage users seeking flexibility or better raw performance.

UGREEN, while newer and still building out its software platform, delivers excellent hardware value and impressive flexibility for the price. It supports a wide range of third-party drives, offers strong virtualization and AI capabilities, and even allows OS replacement—making it highly appealing to power users and technologists. While it may not yet match Synology in software maturity or enterprise security, it is evolving rapidly and clearly resonates with a growing segment of the NAS market. For buyers focused on hardware, performance, and freedom of customization, UGREEN may be the better choice today. For those seeking long-term support, stable software, and enterprise-grade functionality, Synology still sets the benchmark across the rest of the NAS industry in terms of providing an all covering solution, though there is no denying that buyers are getting a little more cost aware. Synology clearly has it’s eyes on bigger prizes right now, and perhaps this is a growing gap in the market that UGREEN is eying up – knife and fork in hand!

Synology vient d’annoncer l’arrivée prochaine d’un nouveau modèle de NAS : le DS925+. C’est le premier modèle de la nouvelle génération DSx25. Au programme : un processeur AMD Ryzen V1500B, 4 Go de RAM DDR4 ECC, et surtout deux ports réseau 2,5 Gb/s. Mais ce n’est pas tout…

Synology DS925+

Alors qu’il est attendu un peu plus tard en France, Synology vient de mettre en ligne la page produit du DS925+ en anglais. Il s’agit d’un NAS 4 baies, capable de recevoir une unité d’expansion de 5 baies supplémentaires, pour un total de 9 emplacements.

Ce nouveau boitier réseau repose sur un processeur Quad Core AMD Ryzen V1500B cadencé à 2,2 GHz, épaulé par 4 Go de RAM en DDR4 ECC (extensible jusqu’à 32 Go). C’est le même CPU que celui utilisé dans les modèles DS1621+ et DS1821+. Pour rappel, ce dernier ne dispose pas de GPU intégré (iGPU).

Disque dur & SSD

Le Synology DS925+ propose 4 emplacements pour disques 3,5 pouces (compatibles SSD 2,5 pouces) et 2 emplacements pour SSD NVMe, accessibles par le dessous de l’appareil. Il s’agit également du premier modèle  à restreindre officiellement la compatibilité aux disques durs et SSD Synology. Pour le moment, aucun autre disque n’est certifié comme compatible pour ce NAS.

Connectique

Côté connectique, le DS925+ est équipé de :

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

C’est tout… et c’est suffisant pour beaucoup.

On notera que Synology répond enfin à une demande récurrente des utilisateurs : la présence du Multi-Gig en standard. En revanche, contrairement au DS923+, le port PCIe a disparu. Ce dernier permettait de recevoir une carte 10 Gb/s.

DSM 8.0 ?

Le NAS sera livré avec DSM 7.2.2. Le fabricant ne fait aucune mention de la prochaine version de son système.

Prix et disponibilité

Le prix officiel du DS925+ n’a pas encore été communiqué par Synology. Toutefois, plusieurs fuites circulent déjà (avec 551£ au UK). La disponibilité semble imminente, une question de jours

[edit du 1/05] Le DS925+ vient d’apparaitre sur Amazon.

Pour plus d’informations sur ce nouveau NAS, rendez-vous sur la fiche produit officielle du DS925+…

Réputé pour ses Mini-PC fiables et performants, Beelink élargit son champ d’action avec une toute nouvelle gamme de solutions de stockage réseau : la série ME. L’entreprise chinoise fait son entrée sur le marché des NAS, avec une ambition claire : proposer une alternative compacte, silencieuse et performante aux solutions traditionnelles. Le premier modèle, baptisé Beelink ME mini, sera disponible très prochainement…

Beelink ME mini

Le Beelink ME mini est un boitier avec des dimensions réduites (99 × 99,2 × 98,3 mm) et un poids plume de 730 g. Malgré sa petite taille, il offre une capacité de stockage importante (jusqu’à 24 To) grâce à ses 6 emplacements M.2 SSD NVMe. Le NAS sera décliné en trois coloris sobres et élégants : blanc perle, bleu paon et gris nuit.

À noter qu’une version pré-configurée avec des SSD Crucial sera également proposée.

Architecture

Le Beelink ME mini  est construit autour d’un processeur Quad Core Intel N200 capable d’atteindre 3,70 GHz, épaulé par 12 Go de RAM en DDR5. Une configuration suffisamment musclée pour répondre aux usages typiques d’un NAS moderne, mais aussi pour d’autres fonctions plus complexes, comme le transcodage, exécuter des machines virtuelles, etc.

Connectique

Du côté de la connectique, nous avons :

• 2 ports USB 3.0 Type-A dont 1 à l’avant ;
• 1 port USB 3.0 Type-C à l’avant ;
• 2 ports Ethernet 2,5 Gbps ;
• 1 sortie HDMI ;
• Wi-Fi 6 et Bluetooth 5.2.

Mini PC ou NAS, pourquoi choisir ?

Cloud personnel

Faire du matériel c’est une chose, mais offrir un système complet, performant et ergonomique… c’est plus compliqué. Beelink fait le choix de proposer Windows par défaut sur ses machines. Le fabricant indique « Le système d’exploitation Windows comprend un service de stockage NAS intégré, qui prend en charge la connexion directe entre les téléphones mobiles et les PC au sein du réseau local, facilitant ainsi l’échange et la sauvegarde des données entre les téléphones mobiles et les PC. Polyvalent dans ses fonctionnalités, le ME mini peut être à la fois un mini PC et votre espace de stockage en nuage personnel ».

Enfin, Beelink prévoit également 2 modèles supplémentaires : ME Pro et ME MAX pour des besoins plus avancés.

En synthèse

L’arrivée de Beelink sur le marché du NAS est une bonne nouvelle. Le secteur, dominé par quelques acteurs historiques, avait bien besoin d’un vent de fraîcheur. Si la promesse matérielle est au rendez-vous, reste à voir si l’expérience logicielle sera à la hauteur. Affaire à suivre…

Le Beelink ME mini est déjà disponible en Chine en très faible quantité. Il devrait arriver prochainement sur le marché européen, on espère pour un prix autour des 400€ l’unité.

Synology DS925+ NAS Officially Launches in Eastern Markets – Full Specs and Features Confirmed

ORIGINAL ARTICLE BELOW:

Following early retailer listings and semi-official leaks earlier this year, the Synology DS925+ NAS has now been formally launched in Eastern markets, including Taiwan, Japan, and China. With full documentation and product pages now publicly available, we finally have confirmation of the system’s complete hardware and software capabilities, as well as early indications of pricing and the compatibility of Hard Drives and SSDs (something of a hot button topic of late). As expected, this system builds on the DS923+’s foundation but introduces key changes that shift its performance profile and position within the Synology portfolio once again!

At the heart of the DS925+ is the AMD Ryzen V1500B, a quad-core, eight-thread processor previously used in larger business-class NAS models like the DS1621+, DS1821+, and DS2422+. Its integration into a 4-bay unit marks the first time this CPU has appeared in Synology’s enthusiast/prosumer tier, bringing greater virtualization, multi-user performance, and multitasking efficiency to this class. With a base frequency of 2.2 GHz and TDP of 16W, the V1500B is a lower-power but more scalable chip compared to the dual-core R1600 in the DS923+, which has a higher clock but fewer threads. This change benefits users focused on Docker, VMs, or simultaneous file operations.

Confirmed in the datasheet is the DS925+’s dual 2.5GbE network ports, supporting Link Aggregation (LAG) and SMB Multichannel, allowing up to 5GbE aggregate throughput—a significant improvement over the DS923+’s 2x 1GbE configuration. Expansion also sees a shift: the DS925+ uses the new DX525 expansion unit, connected via USB-C (6Gbps), replacing the legacy eSATA-based DX517. Internally, the system includes four hot-swappable drive bays (3.5″/2.5″ SATA HDD/SSD), and two M.2 2280 NVMe Gen 3 slots for SSD caching or storage pools (when using Synology’s SNV series drives).

Memory support includes 4GB of DDR4 ECC by default, expandable up to 32GB via two SODIMM slots, and the system supports 200TB volumes (with 32GB RAM) and up to 32 internal volumes. Storage management features are as expected from DSM 7.2+, including Snapshot Replication, Hyper Backup, Active Backup for Business, and Hybrid Share. While the system does not support 10GbE upgrades (removal of mini PCIe slot), Synology appears to be emphasizing strong native network performance and reduced complexity over modular upgrades.

Physically, the chassis weighs 2.26kg, has two 92mm fans, and offers 2 x USB 3.2 Gen 1 ports, alongside one USB-C expansion port. It operates within a 0°C to 40°C range, supports high altitudes up to 5,000m, and includes all standard Synology DSM security tools: firewalls, encrypted folders, SFTP, HTTPS with custom ciphers, and Adaptive MFA. As a data platform, the DS925+ supports 500,000 hosted files in Synology Drive, up to 80 Office users, and 150 Synology Chat users. On the virtualization side, it supports VMware, Hyper-V, Citrix, OpenStack, and allows for up to 8 virtual DSMs or VM instances (license-dependent). Surveillance support includes two default camera licenses, and scalable support for up to 40 IP cameras at 1200FPS (H.265), with full integration into Surveillance Station and optional C2 cloud backup.

Synology DS925+ Pricing and Availability

Following the official launch of the Synology DS925+ NAS in Eastern markets—including Taiwan, China, and Japan—we now have more concrete pricing details. In China, the base unit without drives is priced at ¥4,999, which converts to approximately £500 before tax. Pre-configured options are also being sold, featuring combinations of Synology’s own-branded hard drives in 4TB, 8TB, 16TB, and even 64TB arrays. For example, a DS925+ with 2 x 8TB Synology drives (16TB total) is listed at ¥8,469 (~£845 pre-tax), while a fully populated 64TB configuration with 4 x 16TB drives is priced at ¥14,919 (~£1,490 pre-tax). In the UK and other Western markets, the DS925+ is expected to launch in early May, with Amazon UK listings already live very briefly last week before it was taken offline, showing the base unit at £550 including VAT. Here’s a rough estimate pricing table for the Synology DS925+ configurations, converted from Chinese Yuan (CNY) to both US Dollars (USD) and British Pounds (GBP) using the exchange rates as of April 22, 2025 (remember this does not precisely calculate tax across nations and their currencies, so these are for rough guidance only):

• 1 Yuan= 0.1371 USD

• 1 Yuan = 0.1025 GBP​

Note: Prices are approximate and based on exchange rates as of April 22, 2025. Actual prices may vary due to fluctuations in exchange rates and regional pricing policies with regard to inclusive tax at checkout.

The accompanying DX525 5-bay USB-C expansion chassis—which replaces the legacy DX517 and uses a similar metal casing—is priced at £439. These prices align with Synology’s long-standing strategy of maintaining consistent MSRP targets for its 2-, 4-, and 5-bay Prosumer-tier NAS units year-over-year, even when internal hardware evolves.

Synology DS925+ NAS HDD Compatibility in 2025

One of the biggest shifts accompanying the DS925+ release is Synology’s newly enforced drive compatibility policy on 2025 and newer NAS systems. Starting with this model, only drives listed on the official Product Compatibility List (PCL) will be supported during initial installation. At launch, this list consists exclusively of Synology-branded HDDs and SSDs, though Synology has confirmed that it plans to expand the third-party validation program moving forward. This move represents a broader shift by Synology toward an appliance-like ecosystem, citing increased reliability, faster support diagnostics, and significantly reduced system anomalies when validated media is used. According to the company, using listed drives can reduce storage-related issues by up to 40%, while severe disk anomalies on newer systems have reportedly decreased by as much as 88% under the new policy. Even though the DS925+ NAS has not been globally launched, in the regions it HAS been launched (China, Australia and Jopan, at the time of writing) it has opened up access to the DS925+ hard drive compatibility pages. Here is what you will find:

Practically speaking, this doesn’t mean you can’t install third-party drives (e.g. Seagate or WD), but using unlisted drives may limit your access to certain features—such as volume creation, deduplication, disk health analytics, automatic firmware updates, and even eligibility for Synology technical support. Fortunately, drive migrations from older Synology systems are supported, and older Plus series models (up to and including 2024) remain unaffected.

Still, new users and businesses investing in DS925+ hardware should factor these limitations into their decision, especially if they plan on using existing non-Synology drives. We are still awaiting FULL confirmation on the extent of the utility of 3rd party HDDs in realword use however. For example – can you even initialize a Synology DS925+ NAS with unverified Synology Hard Drives? There have been claims online that you cannot – but until this is fully verified, I/we will need to hold off full judgement!

Final Thoughts

The Synology DS925+ marks a meaningful update to the company’s 4-bay Plus series—bringing improvements in multi-core processing, networking, and system efficiency. The shift to a more capable 4-core, 8-thread AMD V1500B CPU, combined with 2.5GbE networking and modernized expansion via USB-C, ensures this model is better suited to the needs of virtualized, multi-user, and SMB environments. Yet, some users will see the removal of the PCIe slot for 10GbE upgrades as a notable loss, especially compared with the DS923+ which retains this feature.

That said, the DS925+ does benefit from many refinements learned across the Synology portfolio, and its arrival coincides with a broader strategy shift—one that tightens integration between hardware and software while prioritizing platform consistency. This NAS is clearly aimed at power users and businesses ready to invest in Synology’s controlled ecosystem, and for those who are fine with that trade-off, it offers a lot of value. However, prospective buyers who are still committed to third-party drives or planning future high-speed networking upgrades may want to carefully weigh their long-term priorities before making a decision.
