Synology DS1525+ NAS Review – A Solid Release, with bizarre compatibility rules
The Synology DS1525+ is the latest entry in the company’s long-running 5-bay Plus series, designed to deliver a flexible and reliable storage solution for small businesses, creative professionals, and advanced home users who require more capacity and functionality than entry-level models but do not need a full enterprise rackmount system. Retaining the familiar compact desktop chassis of its predecessor, the DS1522+, the DS1525+ supports up to 15 drives with two DX525 expansion units and integrates two M.2 NVMe slots for SSD caching or storage pools, catering to workloads that demand higher IOPS and tiered performance. Notably, it moves away from the Ryzen R1600 CPU found in the DS1522+, opting instead for the quad-core AMD Ryzen V1500B, a server-oriented processor that prioritizes file processing and ECC memory support over integrated graphics and media transcoding. This change aligns the system with Synology’s broader SMB product strategy, which emphasizes data integrity and predictable performance under multi-user access rather than consumer-oriented multimedia features.
The DS1525+ also introduces dual 2.5GbE ports, replacing the DS1522+’s four 1GbE ports, and retains a PCIe Gen3 ×2 slot for optional 10GbE network upgrades. These hardware refinements are paired with Synology’s DSM software platform, which continues to offer one of the most comprehensive and secure NAS operating environments on the market. However, as highlighted in testing and the accompanying video review, these benefits are tempered by Synology’s increasingly restrictive hardware validation policies, which limit drive and SSD compatibility and impose artificial constraints on expandability. This review examines the DS1525+ from multiple angles, including design, internal hardware, connectivity, software functionality, and overall value, to help prospective buyers determine whether its trade-offs and strengths align with their needs.
Synology DS1525+ NAS Review – Quick Conclusion
The Synology DS1525+ is a dependable and well-executed 5-bay NAS that strikes a careful balance between reliability, expandability, and ease of use, making it particularly suited for small businesses, creative professionals, and advanced home users looking for a scalable and predictable storage solution. It builds on Synology’s proven design, offering a compact and quiet chassis with hot-swappable drive bays, support for up to 15 drives with expansion units, and efficient cooling that maintains low noise levels even under sustained workloads. Powered by the quad-core AMD Ryzen V1500B processor and equipped with ECC memory—expandable to 32 GB—the DS1525+ handles multi-user file serving, virtualization workloads, and surveillance duties with stability and consistency. The dual rear 2.5GbE ports, with link aggregation and optional 10GbE via the PCIe slot, offer a meaningful upgrade path for network throughput, while the two M.2 NVMe slots allow for SSD caching or dedicated storage pools, further enhancing performance in I/O-heavy tasks. DSM remains one of the most comprehensive and user-friendly NAS operating systems on the market, providing seamless integration of backup, hybrid cloud, collaboration, virtualization, and security tools that save significant administrative time and deliver strong data protection. However, the system also reflects several compromises: the PCIe Gen3 ×2 mini slot limits the bandwidth and physical scope available to high-speed expansion cards, USB ports are restricted to basic storage and UPS use, and NVMe performance is constrained by Synology’s validated SSD options that prioritize endurance over maximum throughput. Furthermore, the transition from four 1GbE ports on the DS1522+ to two 2.5GbE ports on this model sacrifices some redundancy and may necessitate infrastructure upgrades to take full advantage. Despite these limitations, the DS1525+ remains a solid choice for users already invested in Synology’s ecosystem, or for those who value predictable hardware behavior, mature software integration, and quiet, efficient operation over unrestrained hardware flexibility. In environments where DSM’s feature-rich platform and long-term stability are more critical than maximum raw performance or third-party hardware freedom, the DS1525+ delivers a consistent and refined experience.

CONS
Huge limitations on the choice of HDD and SSD Media you can use on this system USB ports limited to basic storage/UPS functionality M.2 NVMe performance has limited scope in current configuration and support
The DS1525+ continues Synology’s established design language, using a compact desktop enclosure measuring 166 × 230 × 223 mm and weighing just under 2.7 kg. The chassis is predominantly plastic on the exterior, with a metal internal frame to support the drive bays and improve rigidity. Although it retains the same overall appearance as the DS1522+, the DS1525+ benefits from thoughtful airflow improvements that enhance thermal performance under sustained workloads. Ventilation is provided by dual 92 mm rear-mounted fans, complemented by side and base vents to maintain consistent internal temperatures even with all five bays populated and two NVMe SSDs installed. The toolless 3.5” drive trays allow quick installation of SATA HDDs without screws, while optional brackets support 2.5” SATA SSDs if required. As noted during testing, the physical build remains sturdy and understated, making it a good fit for office and studio environments where noise and visual distraction are concerns.
In terms of storage flexibility, the DS1525+ supports five native drive bays, each hot-swappable, and accepts a mix of 3.5” SATA HDDs and 2.5” SATA SSDs. The bays are managed by Synology’s DSM software and support all common RAID configurations, including SHR, RAID 5, 6, and 10, enabling users to optimize for capacity, redundancy, or performance depending on their workload. The system can also scale up to 15 drives using two DX525 expansion units, connected via dedicated USB Type-C expansion ports on the rear. Although the move from eSATA to USB-C modernizes the connection standard, it does not significantly increase bandwidth, as it remains limited to approximately 5 Gbps per link, which can become a bottleneck if the expansion units are fully populated with high-speed drives. Despite this, the expandability remains useful for businesses that anticipate growing data storage needs over time, allowing gradual investment rather than a large upfront commitment.
A key design inclusion is the two M.2 2280 NVMe slots located on the underside of the chassis. These slots can be configured as read/write cache for improved random I/O performance or, with Synology’s verified SSDs, as dedicated storage pools. In testing, the NVMe slots were confirmed to operate at PCIe Gen3 ×4 per slot, providing ample bandwidth for most NAS-grade SSDs. However, as pointed out in the video review, the available Synology NVMe SSDs are endurance-oriented and limited in write speed, which may undercut the full potential of these slots for high-throughput storage pools.
The slots also remain restricted by Synology’s SSD validation policy, which prevents the use of competing brands and forces users to choose from Synology’s own range of NVMe drives, which are often more expensive and limited in capacity. Nonetheless, the M.2 slots provide additional flexibility for workloads that benefit from caching or tiered storage setups, particularly in virtualized or database-heavy environments. Another important design consideration is the thermal and acoustic behavior of the DS1525+ when fully populated and under sustained load.
During extended testing with five 7,200 RPM Synology HAT5300 HDDs and two NVMe SSDs, surface temperatures remained within acceptable ranges, averaging 38–43°C around the chassis and 65–70°C on the NVMe drives. The rear fans were able to maintain stable temperatures across the system even with high drive activity, and they support multiple fan profiles (Quiet, Cool, Full-Speed) for users to balance noise and cooling performance. The plastic chassis construction helps keep overall noise levels lower than metal-bodied alternatives, with measured idle noise between 36–39 dBA and peak noise under heavy load reaching around 52–55 dBA when using high-RPM drives. While not silent, it is unlikely to be disruptive in most office or home environments, especially when placed out of direct proximity to users.
Lastly, the DS1525+’s storage features are tightly integrated with Synology’s DSM platform, which supports a maximum single volume size of up to 108 TB (or 200 TB with sufficient memory). RAID migrations, volume expansions, and global hot spares are supported across all common RAID types, making it easy to adjust storage configurations as needs change. For businesses, the ability to expand storage on demand, coupled with snapshot and replication tools in DSM, ensures data resiliency and flexible recovery options. However, the strict hardware validation policy remains a limitation; users migrating from older systems with non-Synology drives may encounter warnings, inability to expand arrays, or even outright initialization failures with unsupported drives. This policy makes it essential to plan storage purchases carefully and verify compatibility prior to deployment.
Synology DS1525+ NAS Review – Internal Hardware
At the heart of the DS1525+ is the AMD Ryzen V1500B processor, a quad-core, eight-thread 64-bit CPU running at 2.2 GHz. This server-class embedded chip is designed primarily for file processing and multi-threaded workload stability, and its inclusion aligns with Synology’s focus on predictable performance and ECC memory support over multimedia capabilities. Unlike the Ryzen R1600 found in the earlier DS1522+, which offers higher clock speeds and integrated graphics, the V1500B omits hardware media encoding and transcoding support entirely, reflecting Synology’s deliberate pivot toward business-oriented file operations rather than consumer-grade media streaming.
The processor is soldered to the mainboard and not user-replaceable, but it provides sufficient compute power for services like Btrfs snapshots, high-volume SMB/NFS file serving, virtualization with up to eight recommended VM instances, and running multiple DSM applications simultaneously. Its support for ECC memory is particularly valuable in critical environments where data integrity is paramount, reducing the risk of corruption during power events or high load.
The system is equipped with 8 GB of DDR4 ECC SODIMM memory as standard, installed as a single 8 GB module. The motherboard provides two SODIMM slots, supporting up to 32 GB of total memory using 16 GB modules in a dual-channel configuration. This memory ceiling is adequate for typical SMB workloads, virtualization, and even moderate database applications, though users with heavier VM demands or larger hybrid cloud deployments may want to upgrade early. Synology strongly recommends using only validated Synology memory modules, as DSM will display warnings if unvalidated modules are detected, and technical support may be limited. During testing, the standard 8 GB configuration was sufficient for running DSM with multiple file shares, virtual machines, snapshot tasks, and background indexing processes without hitting memory bottlenecks. The memory can be easily accessed and upgraded by removing the side panel of the chassis, which is designed for straightforward maintenance.
Thermally, the DS1525+ maintains internal component stability even under full load. The processor is passively cooled, relying on the dual rear 92 mm fans for airflow across the entire system. Temperature readings during stress tests remained within specification, though the V1500B’s higher TDP compared to Intel Atom or Celeron CPUs results in slightly elevated baseline power consumption. The internal layout remains organized and clean, with the M.2 slots located on the underside of the chassis, separate from the mainboard and drive bays. This prevents localized hotspots and allows the fans to maintain airflow across all critical components, including memory and storage. Users should note that while the PCIe Gen3 interface supports expansion cards, the available slot is limited to ×2 link width, reflecting the moderate bandwidth needs of most NAS workloads but potentially constraining advanced 10GbE or multi-SSD configurations. The overall hardware architecture reflects a deliberate balance between cost efficiency, reliability, and the target workload profiles Synology intends for this model.

Synology DS1525+ NAS Review – Ports and Connections
The DS1525+ offers a streamlined set of connectivity options that aim to balance modern bandwidth requirements with compatibility and expandability. On the rear panel, the system features two RJ-45 2.5GbE network ports that replace the four 1GbE ports found on the DS1522+. These ports support link aggregation, failover, and SMB Multichannel for improved throughput and redundancy, but users will need a compatible 2.5GbE or multigigabit switch to fully realize their potential.
For users requiring more network bandwidth, Synology provides a PCIe Gen3 ×2 expansion slot that can accommodate an optional 10GbE NIC, allowing the system to scale up to much higher transfer rates when used in demanding environments such as large media libraries or high-concurrency file sharing. This combination of onboard 2.5GbE and optional 10GbE caters to a wide range of deployment scenarios, though the move from four ports to two may disappoint users who previously relied on the additional ports for VLAN separation or increased failover granularity.
In addition to networking, the DS1525+ includes two USB 3.2 Gen 1 Type-A ports, positioned on the rear, which support basic external storage and UPS connections. Unlike earlier models that offered limited support for USB accessories, the DS1525+’s USB implementation is largely relegated to these basic functions, and it does not support more advanced use cases like external GPUs or high-speed data ingest beyond the capabilities of USB 3.2 Gen 1. The USB ports are adequate for attaching backup drives or monitoring UPS status but are otherwise limited in functionality. Adjacent to the USB ports are two USB Type-C expansion ports that allow connection of up to two DX525 expansion units. While the move to Type-C modernizes the connector form factor, these expansion ports are still based on a SATA-equivalent bandwidth of roughly 6 Gbps per link, limiting their aggregate performance potential. Nonetheless, they enable storage scalability from five to 15 bays, maintaining a clear upgrade path without requiring a complete system replacement.
Physically, all ports are located on the rear panel, keeping the front of the chassis clean and accessible for drive access. The PCIe slot is located internally, and installing an expansion card requires removing the top panel. Users who need the optional 10GbE NIC should plan for this additional step during setup. Power input is handled through an internal 120W AC adapter, eliminating the need for an external brick and contributing to the system’s tidy cabling.
The system also supports Wake-on-LAN and power recovery, allowing administrators to automate power cycles and recover from outages remotely. The inclusion of two 2.5GbE ports reflects Synology’s incremental approach to adopting higher-speed Ethernet standards while maintaining affordability, but it also highlights the relatively modest ambitions of this generation when compared to competitive NAS units that have already adopted four-port 2.5GbE or standard 10GbE onboard configurations.

Synology DS1525+ NAS Review – Speed, Noise and Power Consumption Tests
The DS1525+ demonstrates controlled acoustic performance that is in line with its intended use in office or home environments. The dual 92 mm rear fans operate in three selectable profiles — Quiet, Cool, and Full-Speed — allowing users to adjust the balance between noise and cooling efficiency. During testing with five Synology HAT5300 7,200 RPM drives and two NVMe SSDs installed, idle noise levels were measured at approximately 36–39 dBA in Quiet mode, which is noticeable but unlikely to disturb most users. Under moderate load in Cool mode, noise levels increased slightly to around 37–40 dBA, while Full-Speed mode produced more airflow and reached approximately 43–45 dBA with minimal vibration. Peak noise occurred when the drives were under heavy access and the fans at maximum speed, reaching 52–55 dBA. As noted in the video review, at that point the drive mechanics themselves were more audible than the fans, especially when using high-RPM or larger capacity HDDs. Overall, the system remains suitable for placement in proximity to users as long as larger enterprise-grade drives are avoided.
In terms of power consumption, the DS1525+ is modestly more efficient than earlier generations, though still higher than lower-power Celeron-based alternatives due to the Ryzen V1500B’s higher baseline TDP. In the lowest idle state with no drives installed, the system consumed approximately 16.7–16.8 watts, which can be further reduced through DSM’s scheduled hibernation features. With five 4TB 7,200 RPM drives installed and idle, power draw increased to around 41–42 watts. During active workloads with all drives accessed simultaneously and a 10GbE NIC installed, power consumption peaked at roughly 60–68 watts, which is reasonable given the system’s capacity and workload. When tested using only the SSD storage pool over 10GbE, power draw settled between 53–58 watts, reflecting the efficiency of the NVMe SSDs but also the fact that the Ryzen CPU remains engaged during high-throughput operations. These figures highlight that while the DS1525+ is not among the most power-frugal NAS options, it remains within acceptable limits for its class.
Performance testing covered several storage configurations and network scenarios to evaluate throughput and responsiveness. Using five Synology HAT5300 drives in SHR and a Synology E10G22-T1-Mini NIC installed for 10GbE connectivity, sequential read speeds reached 900–950 MB/s, with write speeds peaking around 800–850 MB/s. This demonstrates that the system can effectively saturate a 10GbE link under optimal conditions with HDD-based arrays. Using only the two onboard 2.5GbE ports with link aggregation, the system achieved approximately 550–580 MB/s combined, which is sufficient for many SMB workloads but falls short of single 10GbE capabilities. NVMe performance was limited by Synology’s validated SSDs, which prioritize endurance over speed, reaching maximum write speeds around 750 MB/s and read speeds closer to 1,000 MB/s in a RAID 0 pool. As noted in testing, higher-performing third-party SSDs are not supported due to validation restrictions, which prevents the system from fully exploiting the NVMe slots’ Gen3 ×4 bandwidth potential.
For real-world mixed workloads, the DS1525+ proved capable of handling simultaneous file sharing, virtual machine hosting, and snapshot operations without significant degradation. Virtualization workloads supported up to eight recommended VM instances, and Surveillance Station operated within specification at up to 40 1080p cameras, though sustained workloads at maximum capacity may benefit from additional memory. File transfers over SMB maintained consistent throughput even under multiple concurrent sessions, and Btrfs snapshot and replication tasks completed within expected timeframes for the test array. The system’s stability and predictability align well with business-focused deployment scenarios, provided users adhere to the validated hardware list and plan network infrastructure accordingly. The key limitations in performance stem not from the hardware itself but from the imposed compatibility restrictions, which may prevent users from selecting higher-performing drives or SSDs.

Synology DS1525+ NAS Review – DSM Software
The DS1525+ runs Synology’s DiskStation Manager (DSM) operating system, which remains a cornerstone of its appeal. DSM combines an intuitive web-based interface with a rich suite of business, backup, collaboration, and security applications that are deeply integrated into the hardware. The operating system leverages the DS1525+’s hardware capabilities fully, supporting Btrfs as the default file system for internal volumes, providing snapshot-based recovery, advanced quota management, and replication options. In this model, DSM supports up to 32 internal volumes, 108 TB per volume (expandable to 200 TB with 32 GB of memory), and all common RAID configurations including SHR for flexible redundancy. File services are comprehensive, with SMB, AFP, NFS, FTP, Rsync, and WebDAV all included, as well as support for Active Directory, LDAP, and Kerberos authentication. The user and group management features allow up to 1,024 user accounts and 256 groups, making it suitable for departmental and SMB environments.
DSM’s package ecosystem enables the DS1525+ to function as more than just a file server. The system supports core Synology applications such as Active Backup for Business, which allows centralized backup of PCs, servers, and cloud services, and Synology Drive, which offers private cloud-style file sharing with file versioning and team collaboration. Hyper Backup facilitates multi-version backups to local or remote destinations, while Surveillance Station turns the NAS into a capable NVR, supporting up to 40 cameras at 1080p. Virtualization workloads are handled through Virtual Machine Manager, which supports up to eight recommended VM instances and integrates with VMware, Windows Server, and Citrix environments. The DS1525+ also supports Snapshot Replication, Hybrid Share for hybrid cloud workflows, and Synology Office and Chat for internal collaboration. The ecosystem continues to prioritize stability, security, and ease of management, which explains its popularity even in the face of growing hardware restrictions.
That said, DSM’s strength also highlights the ongoing tension between software capability and Synology’s restrictive hardware validation policies. The DS1525+ enforces validated drive and SSD lists for full functionality of features like RAID recovery, hot spares, and SSD storage pools. While DSM continues to outperform many competitors in usability and features, these artificial restrictions reduce hardware choice and increase costs. Prospective users should review Synology’s compatibility list before deploying third-party drives, especially if migrating from older systems. For those willing to adhere to Synology’s ecosystem, DSM delivers a mature, reliable platform that simplifies even complex workflows, while maintaining strong security practices and a steady cadence of updates.

The Synology DS1825+ is the latest 8-bay desktop NAS in the company’s established Plus series, positioned as the direct successor to the DS1821+ that launched in late 2020. After a considerable gap of nearly four years, expectations were high for significant improvements in hardware and features to match the evolving needs of small businesses, creative professionals, and advanced home users. Synology has chosen to retain the same AMD Ryzen V1500B processor, a quad-core 2.2 GHz CPU, while doubling the base memory to 8 GB ECC and upgrading the network interfaces to dual 2.5GbE. Notably, the DS1825+ also introduces tighter drive and SSD compatibility controls, supporting only Synology-validated HDDs and NVMe SSDs for storage pools. These decisions have sparked debate within the NAS community over whether the incremental updates and compatibility restrictions justify the increased price point. In this review, we examine how the DS1825+ performs in design, expandability, power efficiency, and software integration, and evaluate its suitability as a flexible yet reliable NAS solution in 2025.
Synology DS1825+ NAS Review – Quick Conclusion
The Synology DS1825+ is a solid but measured update to the company’s long-running 8-bay Plus series, combining a proven and durable chassis design, dependable performance, and the full-featured DSM software ecosystem with only modest hardware enhancements over its predecessor. The system maintains the robust all-metal build quality, excellent serviceability, quiet dual-fan cooling, and eight hot-swappable drive bays, expandable to 18 total with DX525 units for future growth. Notable upgrades include doubling the default memory to 8 GB ECC, scalable up to 32 GB for virtualization and heavy workloads, and replacing the DS1821+’s four 1GbE ports with two faster 2.5GbE ports that support link aggregation, failover, and SMB multichannel to better utilize modern networks. Internally, the Ryzen V1500B processor continues to deliver stable and consistent performance across tasks like file serving, virtual machines, snapshots, and surveillance, but it clearly lags behind newer processors in efficiency, PCIe bandwidth, and GPU-accelerated media handling, limiting its appeal for use cases like Plex transcoding or advanced PCIe storage.
DSM remains the system’s strongest attribute, offering a comprehensive suite of business-grade features including Btrfs snapshots, hybrid cloud replication, Docker, SAN Manager, and support for up to eight virtual machines and dozens of IP cameras, all managed through a user-friendly interface. However, the increasingly strict hardware validation policy for HDDs and SSDs means DSM features such as RAID recovery, hot spares, and SSD storage pools require Synology-verified components, which can drive up costs and limit flexibility compared to earlier models. In our testing, the DS1825+ delivered reliable performance, predictable noise and power levels, and excellent expandability, but it trades openness and cutting-edge hardware for stability, integration, and controlled user experience. It is best suited for buyers already invested in the Synology ecosystem who prioritize seamless software, long-term support, and predictable operation over maximum hardware choice or price optimization. But like many Synology solutions released in 2025, this is a product marred by their increasingly aggressive media compatibility policy and, in months to come, if/when further alternative drives appear on the support lists – many of us will wonder what the point of it all was. This is a solid solution, that is tainted by a significant and artifical shortcoming created by the brand themselves. I still recommend it, but be aware of it’s qwerks.

CONS
Limited drive and SSD compatibility, requiring Synology-validated models Retains older Ryzen V1500B CPU from predecessor launched 2021, lacking GPU Only two LAN ports versus four on the previous generation
The DS1825+ continues Synology’s long-standing chassis design used across its larger desktop NAS models, retaining the familiar all-black metal and plastic enclosure. Measuring 166 mm high, 343 mm wide, and 243 mm deep, and weighing around 6 kg, it maintains the compact footprint expected of an 8-bay system while offering good internal airflow and accessibility. The front panel houses eight tool-less drive trays, each supporting either 3.5” SATA HDDs or 2.5” SATA SSDs, with hot-swapping supported on the main bays. Unlike the predecessor, this model enforces strict validation of drives, allowing only Synology-branded HAT5300 series HDDs and SAT5200/5210 SSDs, a significant limitation compared to earlier generations which were more permissive toward third-party drives. The front panel also features brightness-adjustable LEDs, a power button, and USB 3.2 ports for quick external access.
Internally, the DS1825+ provides two M.2 2280 NVMe SSD slots, designed primarily for SSD caching, but also supporting storage pools when used exclusively with Synology’s own NVMe SSDs. These slots use PCIe Gen 3 x4 links, which is adequate for caching and light storage workloads, though significantly behind what Gen 4-capable SSDs could theoretically offer. Importantly, the M.2 slots do not support hot-swap, and installing SSDs requires removing the chassis cover. The use of these NVMe slots for primary storage pools remains an appealing option for virtualized workloads or high-IOPS applications, albeit limited by the drive selection policy and the modest PCIe 3.0 bandwidth.
For users requiring greater capacity, the DS1825+ can be expanded up to a total of 18 drive bays by attaching up to two Synology DX525 expansion units via rear-mounted USB-C ports. This expandability enables support for larger storage pools as business needs grow, but it is worth noting that the expansion connection bandwidth is limited to USB 3.2 Gen 1 levels, which is equivalent to 5 Gbps, potentially creating a bottleneck if fully populating both expansion units with high-capacity drives. The backward-compatible design allows users of older DX517 units to repurpose them, though at a reduced performance ceiling. Unlike rackmount models, the DS1825+ does not support redundant power supplies or expansion over faster SAS connections.
One of the standout aspects of the DS1825+ remains its toolless drive trays, which include plastic clips for 3.5” drives and mounting holes for 2.5” SSDs. This makes maintenance and upgrades straightforward, and the internal dual 120 mm fans can also be replaced easily if needed. The chassis provides three fan modes—full-speed, cool, and quiet—allowing users to balance between thermal performance and noise levels. Overall, the physical construction remains solid and serviceable, benefiting from the company’s years of refinement in NAS hardware design.
The DS1825+ maintains its reputation for efficient use of space while improving storage scalability options over its older siblings. However, its strict drive compatibility requirements limit flexibility for those who previously mixed and matched drives based on cost or availability – which is a little bit of a dampener when you think about how appealing SHR (Synology htbrid RAID) is with those that gradually upgrade storage over the years in a single RAID pool. While the ability to expand to 18 bays and to leverage SSD caching or pools is welcome, users must carefully plan their deployment around Synology’s approved hardware list to avoid operational warnings or outright incompatibility.
Synology DS1825+ NAS Review – Internal Hardware
At the heart of the DS1825+ is the AMD Ryzen V1500B processor, a quad-core, eight-thread 64-bit CPU running at 2.2 GHz. This is the same embedded server-grade chip used in its predecessor, the DS1821+, and is designed for consistent, reliable file processing and multi-tasking in a NAS environment. The V1500B supports ECC memory and offers a modest power envelope compared to consumer-grade CPUs while delivering sufficient performance for most small business tasks, including light virtualization, high-volume file sharing, and running multiple DSM services simultaneously. Notably, the processor lacks integrated graphics, which means it does not support hardware-accelerated video transcoding—a limitation noted during testing and worth considering for users planning to run Plex or similar media servers. Despite its age and modest clock speed by 2025 standards, the V1500B remains a capable chip in terms of PCIe lane allocation and IOPS throughput for NAS workloads, striking a balance between power efficiency and server-oriented stability.
Memory in the DS1825+ is configured as 8 GB of DDR4 ECC SODIMM out of the box, doubling the 4 GB baseline offered on the DS1821+. The system uses standard SO-DIMM slots and offers two memory slots in total, supporting up to 32 GB (2 × 16 GB) if both slots are populated. During testing, the system correctly reported and utilized Synology-branded ECC memory, which the company mandates for full warranty and support compliance. While technically compatible with some third-party modules, users choosing non-Synology memory risk reduced support and the possibility of system warnings in DSM. The inclusion of ECC memory is crucial for ensuring data integrity, especially in RAID arrays and virtual machine workloads, where single-bit memory errors could otherwise lead to data corruption. In practice, 8 GB is adequate for smaller file-serving and backup scenarios, but users planning to run multiple virtual machines, intensive database applications, or very large volumes beyond 108 TB should strongly consider upgrading to the maximum supported memory to maintain performance under heavier loads.
The DS1825+ includes a single PCIe Gen3 x8 slot, operating at x4 link width, which provides flexibility for network upgrades and additional functionality. This slot supports Synology’s own PCIe expansion cards, including 10GbE NICs and M.2 NVMe SSD adapters for additional caching options. However, as noted during testing, some older or third-party PCIe cards that function on other Synology systems were not recognized by the DS1825+, suggesting firmware-level restrictions similar to the strict drive compatibility policies. This limits user choice somewhat and reinforces Synology’s preference for a controlled hardware ecosystem. The PCIe slot itself is easily accessible after removing the cover and is positioned above the mainboard in line with the rear ventilation path, ensuring adequate cooling for add-in cards even during prolonged operation. While the PCIe slot is a welcome inclusion for future-proofing, its limitations in both bandwidth (Gen3 ×4) and card support should be carefully weighed by users planning advanced configurations.

Synology DS1825+ NAS Review – Ports and Connections
On the back of the DS1825+, Synology has revised the network interface configuration to reflect more modern bandwidth expectations while keeping the overall I/O layout consistent with prior models. The system now features two 2.5GbE RJ-45 LAN ports, replacing the four 1GbE ports found on the DS1821+. This effectively doubles the available aggregate bandwidth compared to its predecessor when used with a compatible switch, while also supporting SMB Multichannel, link aggregation, failover, and load balancing through DSM’s network manager. During our testing, the 2.5GbE ports performed reliably and reached near-maximum throughput when paired with high-speed drives or SSD caching. However, the reduction from four ports to two has been met with mixed reactions, as it removes the option to segment traffic across more physical interfaces, which some users previously leveraged for separate VLANs or dedicated services.
Alongside its LAN ports, the DS1825+ includes three USB 3.2 Gen 1 Type-A ports, two located on the rear and one on the front panel. These ports support external hard drives, SSDs, UPS devices, and a limited number of compatible peripherals. For expansion, the system offers two USB Type-C ports on the rear for connecting DX525 expansion units, each adding five additional drive bays. While the shift to USB-C modernizes the physical connectors compared to the legacy eSATA ports used previously, it is important to note that the underlying bandwidth is still equivalent to USB 3.2 Gen 1 (5 Gbps). This limitation may impact performance if fully populating multiple expansion bays, particularly if configured with high-capacity 7,200 RPM HDDs or SSDs. During our testing, expansion connectivity was stable but not as fast as many users might assume given the Type-C connectors. No additional USB-C functionality for general peripherals is supported—these ports are strictly reserved for expansion chassis.
The system’s PCIe Gen3 x8 slot complements the onboard I/O, providing a pathway for additional high-speed interfaces. Synology’s supported PCIe cards include 10GbE network adapters and additional NVMe SSD adapters, which can unlock greater bandwidth potential or dedicated SSD storage for high-performance applications. However, as discussed in the hardware section, card compatibility is limited to Synology-validated options, and some third-party cards that work in earlier models may not function here. This means users planning to scale beyond the included 2.5GbE must factor in the added cost of Synology’s cards. Physically, the slot and I/O arrangement remain clean and accessible, with sufficient spacing to avoid airflow obstructions, and the internal fans provide adequate cooling even under sustained high-speed transfers.

Synology DS1825+ NAS Review – Heat, Noise and Storage Performance Tests
The DS1825+ maintains the same overall acoustic profile as its predecessor, though some subtle differences emerge in testing due to changes in fan tuning and drive validation. Equipped with two 120 mm rear-mounted fans, the system allows users to select between Full-Speed, Cool, and Quiet modes through DSM. In our tests with eight Synology HAT5300 7,200 RPM drives, idle noise measured between 35–38 dBA in Quiet mode, rising to 39–41 dBA under moderate load in Cool mode. At maximum fan speed, noise levels reached 44–46 dBA, which is audible in office environments but not disruptive. During intensive drive access, with fans set to Auto, the system balanced cooling with acoustics, averaging 48–50 dBA. It’s worth noting that drive selection significantly affects perceived noise—higher capacity drives or older models with louder bearings can exceed these figures. The fans remain easy to replace and are effective at maintaining stable internal temperatures even during sustained RAID rebuilds or virtualization workloads, underscoring Synology’s mature thermal management design.
In terms of power consumption, the DS1825+ exhibits predictable behavior for a system of this size and hardware configuration. With no drives installed, idle power draw measured around 21–22 watts with one LAN port active. Fully populated with eight HAT5300 HDDs and left idle with fans on Auto, consumption increased to a baseline of 57–62 watts. This rises further during drive-intensive operations, with power usage determined primarily by the number and type of drives installed—HDDs can draw between 3–10 watts each depending on workload. The Ryzen V1500B is not an especially low-TDP processor, but its efficiency under file-serving workloads keeps total system power reasonable. DSM allows users to fine-tune power use further through features such as scheduled on/off, drive hibernation, and Wake-on-LAN, which proved reliable during testing. Compared to smaller NAS systems, the DS1825+ naturally consumes more power due to its larger drive count and internal fans, but remains efficient relative to comparable 8-bay business-class models.
Performance of the DS1825+ aligns closely with the DS1821+ it replaces, as the core CPU and architecture remain unchanged. In our testing with eight HAT5300 drives configured in RAID 6, sequential read speeds over the dual 2.5GbE ports easily saturated a single link, averaging 290–295 MB/s. When link aggregation was enabled, throughput peaked near 580 MB/s under optimal conditions, confirming the benefit of aggregated connections for large file transfers. When fitted with Synology NVMe SSDs in caching mode, random read and write latencies improved noticeably, particularly in multi-client scenarios or under virtualization workloads. Using NVMe SSDs as storage pools further improved responsiveness but was constrained by the PCIe Gen3 ×4 bandwidth ceiling and limited SSD model options.
For video editing or high-volume content serving, the DS1825+ still benefits from installing a 10GbE NIC, though buyers should factor in the added cost of both the card and compatible network equipment. CPU-intensive tasks like running multiple VMs or DSM apps simultaneously are handled adequately, though media transcoding remains unsupported due to the lack of an integrated GPU.
The system’s flexibility in RAID and storage configurations allows it to adapt to different usage patterns, but it’s clear from our tests that performance is gated more by Synology’s validation policies and hardware constraints than by raw capability. For example, attempts to use third-party SSDs for caching or pools resulted in warnings and reduced feature access, despite the hardware technically supporting them. Similarly, third-party 7,200 RPM NAS HDDs could not be initialized in DSM at all, forcing reliance on Synology’s own drives. This imposed restriction does not impact the system’s fundamental speed or reliability once properly configured but does affect cost and planning. Overall, the DS1825+ delivers solid, predictable performance for its class, but users expecting a generational leap over the DS1821+ may find the gains modest and mostly limited to network throughput and improved default memory.

Synology DS1825+ NAS Review – DSM
The DS1825+ runs Synology’s latest DiskStation Manager (DSM) operating system, providing a consistent and mature software experience across the company’s product line. DSM continues to be one of the strongest reasons to choose Synology, offering a polished browser-based interface, extensive administrative controls, and a large ecosystem of first-party and third-party applications. The DS1825+ ships with the full DSM suite enabled, supporting features like Snapshot Replication, Hyper Backup, Synology Drive, and Virtual Machine Manager out of the box. During testing, DSM performed reliably, with the hardware fully supporting even advanced features like Btrfs file system snapshots, multi-version backups, and iSCSI SAN services. Resource usage remained modest even with several concurrent services running, thanks to the Ryzen CPU and ECC memory ensuring stability and data integrity.
One of DSM’s strengths is its virtualization and containerization support, which the DS1825+ leverages effectively. With its quad-core CPU and up to 32 GB of memory, the system can host several virtual DSM instances or lightweight Linux and Windows VMs via Virtual Machine Manager. Our tests demonstrated support for up to eight recommended VM instances and full compatibility with VMware, Hyper-V, Citrix, and OpenStack environments. The system also handles Docker containers well, although its lack of integrated graphics limits its appeal as a media transcoding server. Surveillance Station also remains fully functional here, with support for up to 40 IP cameras at 1080p H.264 and licensing for two included channels, expandable with additional licenses. This makes the DS1825+ a viable choice for businesses looking to consolidate surveillance storage and general file services on a single platform.
Application support on the DS1825+ aligns with Synology’s broader Plus-series feature set, and DSM’s package center provides easy access to install and manage additional services. The system supports the full suite of collaborative tools such as Synology Office, Chat, MailPlus, and Calendar, with tested limits of around 100 simultaneous users for office productivity and chat workloads. Hybrid Share and C2 cloud integration extend functionality into hybrid environments, allowing users to leverage Synology’s own cloud for offsite replication or shared folders. Synology Drive provides private cloud file synchronization for up to 100 users and over a million hosted files, making the system suitable for medium-sized teams. While the strict hardware validation policies discussed earlier extend to SSDs and HDDs, they do not affect DSM’s software features, which remain fully unlocked and accessible regardless of drive choice.

Synology DS1825+ NAS Review – Verdict and Conclusion
The Synology DS1825+ is a competent evolution of the company’s long-running 8-bay Plus series, offering measured yet meaningful updates in key areas such as default memory, network bandwidth, and support for Synology’s mature DSM ecosystem. The system retains its robust all-metal chassis with a compact footprint, efficient dual-fan cooling, and easy-to-service drive trays and components. The addition of dual 2.5GbE networking, which supports link aggregation and SMB Multichannel, better aligns with current network environments, though it still requires compatible switches to fully realize its bandwidth potential. The upgrade to 8 GB ECC memory by default, scalable up to 32 GB, provides headroom for virtualization workloads and ensures data integrity during multi-threaded operations like iSCSI SANs and virtual machine hosting. In practice, the DS1825+ performed reliably across all tested DSM features, including Snapshot Replication, Hybrid Share, and Synology Drive, even under heavier RAID 6 configurations. Noise and power consumption stayed within the expected range for an 8-bay business-class NAS, and its expandability to 18 bays via DX525 units ensures the DS1825+ remains a viable option as storage needs grow over time. Taken together, it offers a dependable and familiar experience that continues to serve Synology’s target audience well.
However, the DS1825+ is equally defined by compromises that prospective buyers must consider carefully before purchase. Synology’s increasingly rigid compatibility policies for both HDDs and NVMe SSDs significantly reduce flexibility and raise costs, as users are now effectively required to source only Synology-validated drives to avoid warnings and to unlock certain DSM features like RAID recovery, hot spares, and SSD storage pools. The hardware platform itself, anchored by the now four-year-old Ryzen V1500B processor, has not evolved meaningfully, leaving it without GPU-based transcoding capabilities and limiting PCIe bandwidth to Gen3 ×4 for both add-in cards and NVMe slots. The replacement of the DS1821+’s four 1GbE ports with only two 2.5GbE ports arguably improves aggregate throughput but sacrifices the port density some environments depend on for VLANs or dedicated service segregation. As noted in our testing, PCIe card support also remains restricted to Synology’s own validated models, further constraining upgrade paths for networking or SSD configurations. For those deeply invested in Synology’s ecosystem and who value its software integration and long-term reliability over hardware flexibility, the DS1825+ remains a strong choice that delivers on stability and ease of use. For users prioritizing maximum hardware control, wider component compatibility, or newer processing capabilities, competing platforms with more open policies may better suit their needs. Ultimately, the DS1825+ continues Synology’s tradition of reliable and controlled NAS solutions, but with a narrower appeal than in previous generations.

Synology vient de mettre en ligne une nouvelle version de son logiciel interne pour ses NAS : DSM 7.2.2-72806 Update 4. Le fabricant n’avait pas fourni de mise à jour depuis 5 mois. Cette dernière est assez importante, car elle vient corriger plusieurs failles de sécurité. Nous vous recommandons chaudement de l’appliquer. Regardons de plus près…
Synology DSM 7.2.2 Update 4
L’arrivée de DSM 7.2.2 date de septembre 2024 et cette version avait fait grand bruit. Synology avait pris plusieurs décisions radicales, comme la désactivation des fonctions de transcodage et la suppression de l’application Video Station. Depuis, 3 mises à jour correctives ont été publiées… et puis plus rien pendant 5 mois.
DSM 7.2.2 Update 4 ne propose aucune nouvelle fonctionnalité. Il s’agit uniquement de correctifs, mais ceux-ci sont critiques. Voici ce qu’indique le journal des modifications :
Correction d’une faille de sécurité concernant la bibliothèque SDK (CVE-2025-8024).
Correction de plusieurs failles de sécurité.
Synology indique la correction de la CVE-2025-8024. Or, aucune vulnérabilité n’est répertoriée sous cet identifiant. Serait-ce le CVE-2024-8024 ? Ou la référence d’une faille non dévoilée pour le moment. La seconde ligne du journal des modifications est encore plus évasive.
Malgré ce flou, le constructeur n’a pas pour habitude de publier des mises à jour sans raison valable. Il est donc raisonnable de penser que cette version corrige des vulnérabilités sérieuses.
Comment télécharger et installer DSM 7.2.2 Update 4 ?

Synology Hard Drives and SSD Comparison with Seagate/WD/Toshiba and More – Deal Breaker?
In recent years, Synology has steadily moved toward a more vertically integrated hardware ecosystem, and the arrival of the 2025 generation of NAS systems marks a significant escalation in that approach. With a much stricter verification process for compatible storage media—covering both hard drives and SSDs—Synology now appears to heavily prioritize its own branded storage. This shift has sparked widespread debate across the NAS community, particularly as many long-time users of Seagate IronWolf, WD Red, and Toshiba NAS drives find themselves increasingly locked out of certain key features like RAID expansion, hot spare assignment, and recovery operations unless using “verified” drives. What’s more, while some of Synology’s media are rebranded and firmware-modified versions of familiar drives from Seagate and Toshiba, the pricing and compatibility limitations often leave users puzzled—and frustrated.

In response to growing user concern, we conducted a comparison of Synology’s drive lineup against the current offerings from Seagate, WD, and Kingston—analyzing each in terms of price per terabyte, real-world performance, durability specifications, and availability. Drawing from direct benchmarking, manufacturer datasheets, and controlled NAS testing environments, this article aims to answer a key question: is Synology’s branded media actually worth the premium? While some users may welcome the simplicity of a one-brand ecosystem, others are understandably wary of higher costs, limited SKU availability, and the potential long-term implications of vendor lock-in. Let’s break down what Synology drives really offer—and where they fall short—compared to the tried and tested alternatives on the market.
Synology Hard Drives and SSDs – What Drives Are There to Buy?
Synology’s storage media catalog is divided across value, prosumer, enterprise SATA, and SAS hard drives, alongside both SATA and NVMe SSDs. While these drives carry the Synology name and firmware, they are not designed or manufactured in-house. Instead, Synology rebrands OEM hardware from established vendors: Toshiba for the enterprise SATA and SAS drives, Seagate for the value-tier NAS HDDs, and Phison-based platforms for SSDs. The internal firmware is customized by Synology to integrate tightly with DSM, and in some cases, to restrict compatibility to only their branded drives within the latest 2025 NAS systems.
The naming scheme makes it easier to distinguish between drive classes:
HAT for SATA NAS hard drives
HAS for SAS enterprise drives
SAT for SATA SSDs
SNV for NVMe SSDs
This segmentation aims to help users align their hardware with expected durability (e.g. workload in TB/year), power loss protection, and RAID integration. However, it’s worth noting that several of these drives are virtually identical to third-party counterparts—particularly in the HAT3300 and HAT3310 lines, which closely mirror Seagate IronWolf models down to mechanical structure and spec. Despite this, third-party versions of those drives remain incompatible with key RAID features on the latest Synology systems unless they are officially “verified.”

While Synology’s branding suggests ecosystem cohesion, it’s essential to recognize that their drive firmware is not engineered for general-purpose systems. These drives are optimized—and in some cases restricted—for Synology NAS environments. However, performance benchmarks show that Synology drives often perform equivalently or slightly below their third-party counterparts in synthetic and real-world tests. Moreover, price comparisons reveal a 5–15% markup on average in the value tier, and significantly higher deltas—often exceeding 30–40%—in the enterprise-class and SSD segments. Combined with regional supply inconsistencies and limited SKU availability, the value proposition of Synology-branded drives remains hotly debated, especially when identical hardware from Seagate or Toshiba can be purchased for less—if only the 2025 NAS series would support them natively.
Synology Hard Drives and SSDs vs Seagate, WD, etc – Price per TB and Value
When it comes to entry-level NAS hard drives, the price differences between Synology’s HAT3300 and HAT3310 series and their third-party equivalents—such as Seagate IronWolf and WD Red Plus—are generally modest. In most cases, the cost per terabyte (TB) stays within a 0% to 15% margin, with Synology’s versions sitting slightly higher. For casual or home users who just want a drive that “just works” out of the box and benefits from firmware-level integration with DSM, that small premium might feel justifiable.
But the story changes dramatically as we move into prosumer and enterprise territory. Drives like the Synology HAT5300 and HAS5300 series can cost 40%–50% more than Seagate IronWolf Pro, WD Red Pro, or Seagate Exos alternatives—despite sharing the same mechanical internals in many cases. These aren’t just marginal differences; when you’re building a multi-drive RAID array with 12TB or 16TB drives, that pricing gap quickly snowballs into hundreds or even thousands of dollars extra. And this is particularly frustrating when, for example, Synology’s 12TB HAT5300 (built on Toshiba hardware) costs nearly double what a comparable IronWolf Pro sells for, despite similar endurance ratings and warranty terms.

In short, while Synology’s drives are built on reputable platforms and do offer advantages like verified DSM integration and predictable firmware behavior, the value proposition becomes questionable—especially in higher capacities and enterprise deployments. For many users, especially SMBs and home power users deploying multi-drive setups, that extra 40–50% markup can be hard to justify. When the mechanical hardware is near-identical and the only major differentiator is firmware control, it’s no wonder many are pushing back against this pricing structure.)
SYNOLOGY DSM Storage Manager Benchmarks (1st and 3rd Party Drive Media)
Zoom in to see the results. IMPORTANT that you keep in mind that these SSDs and HDDs are different capacities and therefore direct comparison and correlation between their performance is not fair – I include these because I think it is important to compare the general gist of using Synology HDD media in a system and then alternatives, but measured with Synology’s in-system tools. Larger capacities mostly tend to yeald better results in any brand of drive (not a ‘do-or-die’ rule, but generally true).

IMPORTANT – In the process of upscaling the test result images (as there is a lot crammed in, so I have included the slightly blurred ones here) but I and will replace these with upscaled versions as soon as possible.
When it comes to performance, Synology’s hard drives and SSDs generally stay within expected ranges for their class—but with some caveats. Most of their HDDs mirror the performance of the OEM drives they’re based on, particularly in the HAT3300 and HAT3310 lines, which perform nearly identically to WD Red Plus and Seagate IronWolf models. You’re looking at familiar specs here: 5400–7200 RPM spin speeds, ~200–280MB/s sequential transfer rates, and ~180TB/yr workload ratings. That’s no surprise, considering these are essentially Seagate or Toshiba drives with Synology firmware and branding. Where things start to scale up, like in the HAT5300 and HAS5300 series, the specs remain on par with their higher-end third-party equivalents. These drives offer 550TB/year workloads, 7200 RPM motors, and MTBF figures around 2.5 million hours—just like IronWolf Pro, WD Red Pro, or Seagate Exos. But Synology currently tops out at 20TB in both SATA and SAS drives, while the competition is already pushing 22TB, 24TB, and even 26TB models. So, if you’re planning a high-capacity build, Synology might already be limiting your options on sheer scale alone.

Performance parity continues with Synology’s SATA SSDs. The SAT5221 and SAT5210 series are very close in spec to Kingston’s DC600M drives, offering similar read/write speeds, IOPS performance, and endurance levels. The SAT5210 even pushes into ultra-DWPD territory, boasting up to 10,000 TBW and higher daily write thresholds, which is competitive in the enterprise space. If you need high write endurance and steady power loss protection, these drives tick the right boxes.
The gap, however, opens up in the NVMe tier. Synology’s SNV3400 and SNV3500 drives fall short compared to third-party NVMe SSDs like the WD Red SN700. While Synology focuses on endurance, PLP (power loss protection), and integration with DSM caching features, the performance ceiling on these drives is noticeably lower—both in terms of sequential throughput and IOPS. Capacities also top out at 800GB, while others offer 1TB and beyond with faster read/write performance. So if you’re after speed or larger NVMe caching pools, Synology’s current options may feel behind the curve.

In short, Synology’s drives generally deliver solid, reliable performance that matches their third-party foundations—but the benefits of full DSM compatibility come with a trade-off. While the SATA range holds its ground, the NVMe lineup is due for an update if Synology wants to stay competitive against higher-capacity, higher-speed SSDs now widely available elsewhere. If performance is your main concern, particularly for NVMe caching or flash-heavy tasks, third-party options may be a better fit unless full integration is a must-have.
Synology Hard Drives and SSDs Guide – The Good and the Bad
In reviewing Synology’s lineup of hard drives and SSDs, it’s clear that the hardware itself is solid—built on trusted OEM foundations and tuned to work seamlessly within DSM environments. From a compatibility and reliability standpoint, these drives do offer advantages, particularly for users who want an integrated, no-hassle deployment. That said, these benefits come with notable trade-offs. In many cases, Synology’s drives are mechanically identical to models from Seagate, Toshiba, or Phison, yet priced significantly higher—especially in the enterprise and NVMe tiers. While some of that premium may be justified by firmware-level integration, PLP, or simplified support paths, the cost disparity is hard to ignore for experienced users already comfortable with third-party hardware.
Ultimately, the decision to adopt Synology-branded drives will depend on your priorities. If you’re building a system where out-of-the-box compatibility, long-term support, and unified ecosystem control are paramount, Synology’s media may be a safe bet—albeit at a higher packaged price. But if your focus is on maximizing performance per dollar, scaling capacity, or customizing your setup beyond Synology’s verified list, third-party alternatives remain the more flexible and cost-effective choice. Until Synology expands their verified media list and adjusts regional pricing or availability, many users will continue to see these drives not as a value-add, but as an imposed requirement.

Un vaste coup de filet mené par la police italienne, avec le soutien de la France, de la Roumanie et d’Europol, a permis de démanteler le groupe criminel derrière un rançongiciel touchant les NAS Synology…
Menace sur les NAS Synology
Depuis 2021, le gang opérait sous différents noms « DiskStation Security », « Quick Security », « LegendaryDisk Security », ou encore « Umbrella Security ». Leur objectif : infiltrer des NAS mal sécurisés exposés sur Internet. Les méthodes utilisées incluaient :
Attaques par force brute ;
Exploitation de failles connues ou 0-day.
Conséquences très lourdes
Les cibles étaient principalement des PME, des ONG ou des sociétés du secteur événementiel. Une fois les NAS chiffrés, les criminels exigeaient des rançons en cryptomonnaie pouvant atteindre plusieurs centaines de milliers de dollars. Sans paiement, les données restaient inaccessibles, paralysant totalement l’activité.
Enquête et arrestations en Roumanie
L’enquête, dirigée par le parquet de Milan, s’est appuyée sur des spécialistes en criminologie numérique et d’analyste de blockchain. En juin 2024, une opération conjointe a permis d’arrêter plusieurs suspects lors de perquisitions à Bucarest.
Une réseau bien structuré
Le groupe était organisé en cellules distinctes :
Intrusion et compromission ;
Chiffrement et déploiement des rançons ;
Blanchiment des paiements en cryptomonnaies.
Le principal suspect, un Roumain de 44 ans, est aujourd’hui en détention provisoire à Milan. Il est poursuivi pour accès illégal à un système informatique et extorsion.
Une coopération européenne décisive
Baptisée opération Elicius, cette intervention est un exemple concret de la coopération transfrontalière. L’Italie, la France, la Roumanie et Europol ont mutualisé leurs compétence. Ce type de collaboration devient indispensable face à des cybermenaces de plus en plus sophistiquées.
L’opération a été tenue secrète (jusqu’à présent) pour des raisons stratégiques. Les autorités ont attendu la consolidation des preuves et la mise en détention des principaux suspects avant toute communication. La révélation intervient aujourd’hui, car le procès serait en préparation.
Conseils pour sécuriser un NAS Synology
On a cesse de vous le rappeler, les NAS sont devenus des cibles fréquentes en raison de leur accessibilité depuis Internet et de leur mauvaise configuration. Pour rappel, quelques bonnes pratiques :
Mettre à jour régulièrement le système de votre NAS et les applications ;
Désactiver les services inutiles (Telnet, SSH, UPnP) ;
Ne pas exposer le NAS directement à Internet (utiliser un VPN) ;
Utiliser des mots de passe forts et activer l’authentification multifacteur (MFA) ;
Sauvegarder régulièrement les données importantes et conserver une copie hors ligne.
En synthèse
Le démantèlement de ce gang est un succès dans la lutte contre les rançongiciels visant les NAS Synology. Cette opération montre que les cybercriminels, même organisés à l’échelle internationale, peuvent être identifiés et arrêtés. Mais la menace reste bien réelle…
Une configuration sécurisée des NAS et une bonne hygiène numérique sont essentielles pour s’en prémunir. La vigilance reste la meilleure défense face à une cybercriminalité toujours plus sophistiquée.
30TB Seagate Ironwolf Pro and EXOS HDD Review – When is Enough, Enough?
The arrival of 30TB capacity hard drives from Seagate — in the form of the IronWolf Pro ST30000NT011 and the Exos M ST30000NM004K — marks another incremental step in high-capacity storage for NAS and enterprise environments. Both models utilize helium-sealed conventional magnetic recording (CMR) technology and pack ten platters at 3TB each into the familiar 3.5-inch form factor. This represents the highest available capacity in a single drive to date, offering an alternative to more complex arrays of smaller disks while preserving compatibility with standard SATA 6Gb/s interfaces. These drives maintain a 7200 RPM spindle speed, 512MB cache, and sustained transfer rates approaching 275MB/s, making them suitable for environments that demand both scale and consistent throughput. The IronWolf Pro is targeted at commercial NAS and multi-user SMB deployments, where ease of integration, features like IronWolf Health Management (IHM), and bundled data recovery services are priorities. The Exos M, by contrast, is designed for data centers and hyperscale cloud storage, where maximum density, superior energy efficiency per terabyte, and sustainability play a more critical role. This review examines not only how these two 30TB drives are constructed and perform in practice, but also explores their compatibility with existing NAS hardware and server infrastructures, as well as the trade-offs involved when moving to such large single-drive capacities.
Seagate 30TB Ironwolf Pro and EXOS Hard Drive – Quick Conclusion
The Seagate IronWolf Pro 30TB and Exos M 30TB represent the cutting edge of mechanical storage, delivering unprecedented density in a standard 3.5-inch, SATA-compatible form factor. Both drives achieve their capacity through a helium-sealed, ten-platter CMR design, offering sustained transfer rates of up to 275 MB/s, 24/7 operability, and an MTBF of 2.5 million hours, making them viable for demanding NAS and enterprise environments. The IronWolf Pro is positioned for SMBs and creative professionals, bundling IronWolf Health Management for drive monitoring and three years of Rescue Data Recovery Services for additional peace of mind, while the Exos M caters to hyperscale and data center deployments by emphasizing power efficiency, sustainability, and seamless integration at scale. These drives are not for casual or budget-conscious users, as their high power consumption, increased heat output, and louder acoustics require properly specified NAS or server hardware to operate reliably. Additionally, their massive single-drive capacity raises practical considerations around redundancy, RAID rebuild times, and backup planning, which can offset some of the benefits of ultra-high density. Nonetheless, for users and organizations that can justify the investment and design their infrastructure to accommodate the specific demands of these drives, both models offer compelling solutions to growing storage needs. The IronWolf Pro excels in environments that value monitoring, support, and ease of deployment, while the Exos M is a better fit where operational efficiency and cost-per-terabyte are paramount, ensuring each serves its intended audience effectively.

Both the Seagate IronWolf Pro 30TB and Exos M 30TB maintain the standard 3.5-inch hard drive form factor, measuring 26.1mm in height, 101.85mm in width, and 147mm in depth, with a typical weight of 695 grams. This adherence to established dimensions ensures seamless integration into existing NAS bays, server racks, and JBOD enclosures, making them drop-in replacements for lower-capacity drives. Internally, both drives are helium-sealed, a technology critical at this density for maintaining stable platter rotation and reducing turbulence caused by the high number of thin platters spinning at 7200 RPM.
Helium also lowers drag and internal air resistance compared to traditional air-filled drives, which helps moderate temperatures and contributes to better reliability over time. The drives incorporate ten platters, each at 3TB, demonstrating how Seagate has pushed areal density to enable 30TB within the same footprint that previously maxed out at 24TB in nine-platter designs.
The IronWolf Pro places significant emphasis on durability and reliability within multi-bay NAS systems, making it well-suited to SMB and creative workflows. It achieves a mean time between failures (MTBF) of 2.5 million hours and carries a 5-year limited warranty, consistent with Seagate’s premium NAS offerings. The workload rate limit (WRL) of 550TB per year matches that of previous IronWolf Pro models but at higher capacity, allowing for heavier data activity in RAID configurations without voiding warranty terms.
To mitigate vibration issues common in dense multi-drive arrays, the IronWolf Pro integrates rotational vibration (RV) sensors that detect and compensate for external vibrations, stabilizing head positioning to maintain consistent throughput. Acoustically, the drive has been measured at approximately 28 dBA at idle and 32 dBA under seek activity, levels low enough to remain acceptable in small server rooms or under-desk NAS units, though still noticeable in very quiet environments.
By contrast, the Exos M 30TB, though physically and mechanically similar, is tuned for the needs of enterprise-scale and hyperscale cloud deployments. Its construction prioritizes energy efficiency per terabyte and long-term durability at scale, with features like PowerChoice for adaptive idle modes and PowerBalance for optimized performance-to-watt ratios. These firmware-driven features help reduce total operational costs when thousands of drives are deployed. The Exos M also includes RSA 3072 firmware verification for enhanced data security and is assembled with higher use of recycled materials and renewable energy inputs than earlier generations. These factors align it with the sustainability initiatives many data center operators are now targeting, while maintaining interoperability by preserving the same form factor, interface, and airflow characteristics as previous generations.
Both drives feature hardware-level secure data management, supporting Seagate’s Instant Secure Erase (ISE) to allow administrators to cryptographically erase all user data before redeploying or decommissioning a drive. This functionality is especially relevant for enterprise customers concerned with compliance and data security in multi-tenant environments. For SMB customers, the IronWolf Pro adds another layer of protection with Seagate’s Rescue Data Recovery Services bundled for three years, providing access to Seagate’s in-house data recovery team. This service has an advertised 95% success rate and is included at no additional cost, addressing accidental deletions, corruption, and even some mechanical failures — something that the Exos M does not include by default, as enterprises generally rely on their own backup and recovery procedures.
Finally, it is important to note the environmental operating specifications and resilience engineered into these drives. Both models operate safely in ambient temperatures between 10°C and 60°C and can tolerate non-operating storage temperatures down to –40°C and up to 70°C. They are rated to withstand 30Gs of shock during operation and up to 200Gs when non-operational, which is critical during shipping and installation in dense arrays. Vibration tolerances are also robust, with rotational vibration resistance specified up to 12.5 rad/s² between 10Hz and 1500Hz. Both require both +12V and +5V power rails and draw a typical 6.8–6.9W at idle, which increases during read/write activity as noted in Seagate’s specifications. Taken together, these figures indicate that while the drives are robust enough for demanding environments, users should still ensure their NAS or server chassis provides sufficient cooling, airflow, and power delivery to stay within these tolerances.
Comparing the 30TB IronWolf Pro to the 24TB IronWolf Pro and 4TB IronWolf (Non‑Pro) for Perspective
The 30TB IronWolf Pro represents Seagate’s largest capacity in the NAS‑optimized lineup, continuing the incremental increase in platter count, areal density, and helium‑sealed design. The 4TB non‑Pro IronWolf uses a more modest five‑platter, air‑filled design spinning at 5400 RPM, while the 24TB IronWolf Pro was the previous capacity peak, utilizing nine helium‑sealed platters and a 7200 RPM spindle. Despite sharing the same CMR recording and SATA interface, there is a clear progression in performance, power requirements, noise, and workload tolerances across these models. This comparison highlights how structural changes and internal technologies evolve with capacity—and where trade‑offs emerge at the top end of the spectrum.

This side‑by‑side comparison makes it clear that the 30TB model pushes beyond earlier limits, with higher power draw, increased acoustic output, and tighter operating conditions. Once you start thinking about larger Petabyte deployments of course, this all becomes small margins towards the big storage goals. But Simultaneously, the non‑Pro 4TB drives offer much gentler power, acoustic, and workload characteristics—making them more suitable for everyday, personal, or small‑office use. I am just glad to see that Seagate are not in any rush to eliminate the smaller tiers now that they are on the road to 50/100TB drives by the end of the decade and reducing the smaller caps in the way we save ‘sub 1TB’ drive dry up as soon as we hit above 4TB a decade ago!
Seagate 30TB Ironwolf Pro and EXOS Hard Drive – Performance, Noise and NAS Compatibility (WiP)
Performance testing of the Seagate IronWolf Pro 30TB and Exos M 30TB confirms that both drives deliver sustained sequential transfer rates close to their advertised 275 MB/s. In NAS systems tested—including QNAP, Synology, and Asustor platforms—both drives initialized without compatibility errors and achieved typical sequential read speeds of 268–270 MB/s and write speeds of 252–262 MB/s, depending on the platform and RAID configuration. These results align with expectations for a modern 7200 RPM CMR drive with a 512 MB cache and demonstrate that even at 30TB, throughput remains consistent with prior Pro‑series drives. Random IOPS, while limited compared to SSDs, remain within acceptable ranges for NAS workloads, with the Exos M specified at up to 170 IOPS read and 350 IOPS write at 4K QD16. Latency is nominal at approximately 4.16 ms, which is typical for this class of mechanical drive. Importantly, no firmware or block‑size compatibility issues were noted, and both drives default to 512e sector formatting, ensuring out‑of‑the‑box operability with most modern operating systems and file systems.
Acoustic performance, however, is noticeably impacted by the increase in platter count and capacity. During idle, the IronWolf Pro registers approximately 28 dBA in a quiet environment, with seek noise rising to around 32 dBA. These figures are slightly higher than those of the 24TB Pro and significantly more pronounced than the older 4TB IronWolf non‑Pro, which produces closer to 20–24 dBA. Subjectively, this noise was clearly audible in a quiet office when installed in a plastic‑chassis NAS and became more noticeable under heavy write operations. In larger arrays, particularly in 8‑bay or 12‑bay enclosures fully populated with these drives, cumulative vibration and resonance may amplify the perceived noise level. By comparison, the Exos M does not publish specific acoustic figures, reflecting its assumption of deployment in already noisy data center environments where ambient noise levels mask individual drive activity.
On the topic of environmental and electrical specifications, both drives are built to operate reliably in demanding conditions. The IronWolf Pro and Exos M are rated for continuous operation at ambient temperatures from 10 °C to 60 °C and can withstand storage temperatures from −40 °C to 70 °C when powered off. Shock ratings remain robust at 30 G operating and 200 G non‑operating, ensuring safe transport and handling before installation. Rotational vibration tolerance of up to 12.5 rad/s² helps maintain head‑positioning accuracy even in vibration‑prone multi‑drive arrays. Power draw, as specified by Seagate, averages around 6.8–6.9 W when idle and rises to between 8.3–9.5 W during typical operating workloads, depending on the model. Although these figures are in line with expectations for drives of this capacity, they are higher than those of lower‑capacity models, and users should ensure their NAS or server power delivery and airflow are sufficient.
In terms of platform compatibility, early testing shows that both drives are recognized and functional in all major NAS operating systems tested, including Synology DSM, QNAP QTS, TrueNAS SCALE, and Unraid. Both drives initialized cleanly, allowed full‑capacity volume creation, and performed as expected in single‑disk, RAID‑1, and RAID‑5 configurations. Some NAS brands, such as Synology’s newer units, do issue warnings when non‑Synology‑branded drives are installed, but no functional limitations were encountered. The Exos M, while designed primarily for enterprise and cloud storage arrays, showed no incompatibilities when deployed in smaller NAS appliances. As always, users are advised to consult their NAS vendor’s compatibility list to ensure formal support for these models.
Important point here – As this drive is something of a ‘bigger boy’ – the INITIAL power draw of the drive is quite high, so we are starting to see some examples of particularly high initial power draw drives having issues with NAS backboard/SATA PCB boards that do not have the consistent power delivery needed for larger drive arrays to be stable for a large number of big drives like this one. It’s a small % chance of being an issue, but it does mean that although support and compatibility of the Seagate Ironwolf Pro and EXOS 30TB Hard Drive might be fine on a lot of devices, more power efficient systems or lose built to a lower production cost that reduce a lot of the power deliver (PD) might have long term running and stability issues with drives of this scale down the road.
Seagate 30TB Ironwolf Pro and EXOS Hard Drive – Conclusion and Verdict
The Seagate IronWolf Pro 30TB and Exos M 30TB drives both exemplify the steady evolution of high‑capacity mechanical storage, bringing unprecedented density to the familiar 3.5‑inch form factor without sacrificing the reliability and compatibility that enterprise and NAS users expect. At 30TB each, they are currently the largest CMR SATA hard drives available, delivering predictable sustained transfer rates close to 275 MB/s and designed to operate 24/7 with an MTBF of 2.5 million hours. Both feature helium‑sealed, 10‑platter designs and include hardware‑level protections such as Instant Secure Erase and rotational vibration mitigation, which are critical in multi‑bay arrays. Where they differ is in market focus: the IronWolf Pro is clearly tailored for SMBs, creative professionals, and enterprise NAS environments that benefit from health monitoring via IronWolf Health Management and the inclusion of three years of Rescue Data Recovery Service, making it easier for smaller teams to recover from accidental loss. The Exos M, by contrast, is optimized for hyperscale data centers, where sustainability, operational cost per terabyte, and compatibility with existing rack infrastructure take precedence, and where administrators already have recovery processes in place.
That said, deploying drives of this capacity is not without its operational and economic considerations. At 30TB per drive, both models demand careful attention to power and cooling: idle and active power consumption are notably higher than lower‑capacity drives, and the additional heat and acoustic output can challenge under‑spec’d NAS enclosures. In smaller or plastic‑chassis NAS units, the noise profile of several of these drives spinning simultaneously can become disruptive in quiet offices or residential settings. Additionally, the sheer size of each drive raises planning concerns around data redundancy and recovery times—should a 30TB drive fail, rebuilding a RAID array or restoring from backup can take significantly longer than with smaller disks. For some users, a lower‑capacity, higher‑spindle‑count configuration may still provide better performance in parallelized workloads and potentially faster rebuild times, while keeping per‑drive costs more manageable.
Ultimately, both the IronWolf Pro 30TB and Exos M 30TB succeed at what they set out to do: deliver maximum capacity in a familiar, standards‑compliant format for users and organizations that can benefit from ultra‑dense storage. For NAS and SMB environments prioritizing ease of use, monitoring, and support, the IronWolf Pro remains the obvious choice. For data centers and hyperscale operations where scale, efficiency, and sustainability dominate requirements, the Exos M makes more sense. Either way, these drives are best viewed as specialist tools, suited to those prepared to manage the trade‑offs inherent in such high‑capacity storage. Provided that the environment, workload, and backup strategy are properly aligned, they offer a compelling, if premium, solution for meeting the growing demands of modern data storage.

The DS925+ delivers a refined hardware experience out of the box, with its newer AMD Embedded Ryzen V1500B 4 Core/ 8 thread processor, dual 2.5GbE ports for faster LAN connectivity, and modern I/O including USB-C. It features two M.2 NVMe slots (for cache only, unless you use the Synology SNV3400 drives from Synology), dual memory slots supporting up to 32GB of ECC DDR4 RAM, and a compact metal chassis designed for quiet, efficient operation. It also runs cooler and quieter than many of its rivals, making it an ideal fit for environments where noise levels matter—such as living rooms, home studios, or small offices. This makes the DS925+ a “plug-and-play” NAS with premium internal components and minimal need for user intervention.
By contrast, the QNAP TS-464 takes a more modular, expandable approach. Powered by the Intel Celeron N5105/N5095 CPU (a quad-core processor with integrated graphics, but only 4 threads), it offers HDMI 2.0 output, two M.2 PCIe Gen3 x1 slots (which can be used for either caching or storage pools), and a PCIe Gen3 x2 slot for optional 10GbE or more M.2s, USB expansion, or even GPU cards. QNAP also includes dual 2.5GbE ports, putting it on par with the DS925+ in terms of network speed, but it edges ahead in overall hardware adaptability. Want multimedia output via HDMI? QNAP has it. Want to add NVMe storage pools or real-time transcoding? QNAP supports that too. That said, the TS-464 is based on a slightly older CPU architecture, lacks ECC memory support, and typically generates more fan noise under load. Additionally, its OS and ecosystem are broader in scope but often require more manual setup. Ultimately, the DS925+ is purpose-built for those who prioritize a quiet, polished, and simplified experience with modern performance. The TS-464, on the other hand, remains an excellent choice for users who prefer control, multimedia support, and greater hardware flexibility. Choosing between them largely depends on whether you value Synology’s stability and turnkey design, or QNAP’s freedom and potential.
AMD V1500B vs Intel N5105 – CPU Specifications (Synology DS925+ vs QNAP TS-464)
In any NAS system, the processor plays a pivotal role in determining the scope of functionality—whether it’s managing multiple concurrent users, running virtual machines, powering AI-driven applications, or simply handling encrypted transfers and background tasks efficiently. The Synology DS925+ and the QNAP TS-464 take noticeably different approaches in this regard. The DS925+ features the AMD Ryzen Embedded V1500B, a server-grade SoC designed for sustained multi-threaded workloads. The TS-464, on the other hand, runs on the Intel Celeron N5105, a more consumer-oriented chip that prioritizes integrated multimedia support and power efficiency. While both CPUs are quad-core, their architecture, instruction set, and target use cases diverge sharply—affecting not only raw processing, but also the capabilities unlocked within DSM and QTS/QuTS, respectively.

In terms of raw specs, the V1500B offers 4 cores and 8 threads with a base clock of 2.2GHz and support for ECC memory—a key advantage for mission-critical environments. This CPU is built for multitasking and thrives in scenarios involving virtual machines, container services, and intensive file indexing or backup operations. As a result, the DS925+ supports up to 8 concurrent virtual machines, 8 virtual DSM instances, and higher thresholds for connected users across Synology apps. It is better suited to offices or power users who rely on services like Synology Office, Drive, or Surveillance Station running in tandem. The system handles up to 150 Synology Chat users, 80 Office users, and 80 Drive users, offering excellent multitasking performance with low overhead.
The QNAP TS-464’s Intel N5105 is a 10nm Jasper Lake processor, also quad-core but without hyper-threading and with a slightly lower base clock (2.0GHz). However, it includes integrated Intel UHD Graphics, giving it one key advantage the DS925+ lacks: hardware-accelerated video transcoding via QNAP’s own QuMagie, Video Station, and especially Plex Media Server with support for on-the-fly 1080p and 4K decoding when paired with proper client-side licensing. This makes the TS-464 ideal for multimedia-heavy environments. Beyond media, the N5105 powers QTS and QuTS hero with access to QNAP’s broader and often more modular ecosystem. This includes Hybrid Backup Sync (HBS 3) for unified backup and disaster recovery, QuDedup for deduplicated snapshot replication, QVR Elite and QVR Pro for professional-grade surveillance (supporting multiple IP camera licenses natively), and AI Core features like face recognition and event detection when paired with the QuMagie or QVR Human apps. The TS-464 also supports Virtualization Station, enabling users to run lightweight Linux or Windows VMs with direct passthrough access to USB or PCIe devices, and Container Station, which offers both Docker and LXC container compatibility with GPU passthrough for NPU-based AI inference workloads. Thanks to the included PCIe Gen 3 x2 slot, the system supports optional upgrades like 10GbE NICs, QM2 expansion cards (for M.2 SSD or additional 2.5GbE/10GbE ports), or even Wi-Fi 6 cards, something entirely absent in the DS925+. Additionally, QNAP allows direct output to an external display via HDMI 2.0, enabling standalone use of HD Station apps like Chrome, LibreOffice, Kodi, and even Linux desktop environments — a feature highly prized in HTPC and security NVR deployments. Users can leverage Linux Station to run full Ubuntu VMs locally, or install Ubuntu Core through the App Center for custom development or edge AI inference scenarios.
Taken together, the TS-464 may not support the same high virtual machine/user count as the DS925+, but it compensates with a broader set of integrated appliances catering to power users, home labs, edge AI, and media-heavy deployments. It’s a more “tinker-friendly” platform, favoring flexibility and breadth over centralized system control and vertical integration. If you need an appliance that works across entertainment, security, and hybrid cloud workflows, with room for add-on functionality via hardware or apps, the TS-464 is hard to beat for the price. That said, the Synology DS925+ ultimately offers greater headroom for enterprise workflows, heavier VM usage, and large-scale hybrid deployments. It sacrifices media transcoding and graphical acceleration, but gains a server-class CPU that ensures consistent performance under heavier load conditions. Meanwhile, the TS-464 excels in edge-case versatility, offering more multimedia flexibility and richer expansion potential via PCIe. If your priorities lie in business-class performance, ECC memory support, and robust multi-user capacity, the DS925+ is the clear winner. But for media streaming, home lab tinkering, and a wider hardware feature set, the TS-464 remains a very compelling alternative.
Synology DS925+ vs QNAP TS-464 – Software Specifications
When it comes to NAS platforms, hardware is only half the story—what truly determines a system’s long-term value is the strength, maturity, and flexibility of its software. Synology’s DSM (DiskStation Manager) and QNAP’s QTS/QuTS Hero are two of the most advanced NAS operating systems available today, offering extensive suites of services for backup, virtualization, hybrid cloud, media streaming, and AI-assisted surveillance. But while both OS platforms cover similar ground, their design philosophies, application depth, and supported workloads differ substantially. The Synology DS925+ and QNAP TS-464, though comparable in price and both aimed at prosumers and SMBs, unlock very different software experiences depending on the deployment goals—be it centralized IT infrastructure, media-rich home labs, or container-based edge computing.
With the DS925+, Synology leans into its strength in unified management and vertical integration. DSM 7.2 is optimized for reliability, simplicity, and scalability within Synology’s ecosystem. The DS925+ supports up to 8 virtual machines and 8 Virtual DSM instances through Virtual Machine Manager, offers extensive group and user quotas, and enables full integration with Synology’s cloud services (such as Synology C2 Backup, C2 Identity, and Hybrid Share). Its higher hardware ceiling allows for more active users: 150 on Synology Chat, 80 on Synology Drive and Office, and up to 8 simultaneous VPN connections. Backup capabilities are similarly robust, with a higher threshold of shared folder sync tasks and superior support for incremental snapshot replication. Surveillance Station on the DS925+ supports up to 40 IP cameras and benefits from reduced CPU overhead during continuous recording, even while handling concurrent backup or media indexing operations. DSM’s elegant UI, consistent updates, and tightly integrated packages make it ideal for organizations that value centralized IT administration and long-term platform stability.
On the other hand, the QNAP TS-464 running QTS 5 or QuTS Hero offers a more open and modular software ecosystem. While the Intel N5105 CPU imposes lower multitasking ceilings than the V1500B, QNAP compensates with a broader set of feature-specific applications and customization paths. The TS-464 supports virtualization through Virtualization Station (for VMs) and Container Station (for Docker + LXC), and unlike the DS925+, can output video directly via HDMI 2.0—allowing the NAS to act as a standalone Linux desktop, NVR, or HTPC via HybridDesk Station. QNAP also differentiates itself with Hybrid Backup Sync (HBS3), which enables multi-destination sync, deduplicated backup via QuDedup, and real-time disaster recovery tools not found in DSM. QVR Pro and QVR Elite offer an expansive surveillance suite with optional AI-powered analytics (e.g., face recognition, people counting) when paired with compatible QNAP AI apps. The inclusion of ZFS with QuTS Hero (an optional OS for the TS-464) enables inline compression, self-healing file systems, and block-level snapshots, which can be critical for data integrity in business scenarios.
QNAP also encourages expansion through its App Center, which includes over 150+ native and third-party apps, from Node.js and GitLab to Home Assistant, Ubuntu Station, and even Mattermost for self-hosted chat. While the system supports fewer concurrent users and VMs than the DS925+, its strength lies in feature breadth and system-level flexibility. Add-ons like 10GbE NICs, QM2 SSD accelerators, or Wi-Fi 6 cards via PCIe further extend its versatility, especially for hybrid edge workloads or multi-role deployments that evolve over time. In short, the Synology DS925+ is designed for administrative simplicity and long-term scaling, excelling in consistent performance across multi-user deployments with deep DSM integration. The QNAP TS-464, meanwhile, is a powerful sandbox for customization, offering greater freedom, multimedia functionality, and third-party integration—at the cost of some operational polish and software limits. Choosing between them depends on whether your priorities lie in predictable enterprise-grade execution or a more adaptable, feature-dense platform.
Synology DS925+ vs QNAP TS-464 – Hard Drive and SSD Compatibility
In 2025, Synology has taken its most aggressive step yet toward locking down hardware compatibility, and nowhere is this more evident than in the DS925+. Following years of gradual restrictions—starting with warnings for unverified drives and progressing to default white-listing only Synology-branded media—the DS925+ now represents a firm line in the sand. At the time of writing, this system will not allow DSM initialization if it detects hard drives or SSDs that are not officially listed on Synology’s compatibility list. This list includes exclusively Synology HAT5300/HAT3310 HDDs and SAT5200 SSDs, with no third-party Seagate, WD, Toshiba, Samsung, or Kingston media currently supported. Regardless of drive quality or performance, unsupported models will be outright blocked during system setup. While Synology claims this guarantees optimal reliability and performance within DSM 7.2, the move drastically reduces flexibility for users and integrators alike.
In stark contrast, the QNAP TS-464 embraces an open compatibility philosophy. It supports virtually all major consumer and enterprise drives—from Seagate IronWolf and Exos, to WD Red, Red Plus, and Ultrastar, as well as Toshiba N300/X300 and Samsung/Kingston SSDs—up to 24TB per drive (or higher as of late 2025). QNAP also maintains a regularly updated compatibility list, but crucially, this list is advisory rather than mandatory. Users can install any 3.5″ or 2.5″ SATA HDD/SSD, and as long as it meets the physical and electrical standards, the TS-464 will initialize without issue. This means integrators, home users, or small businesses can reuse existing drives or select from the most cost-effective options in their region—something that’s increasingly difficult to do on newer Synology units. Moreover, QNAP allows mixing and matching of drive brands and capacities within the same storage pool (especially under QuTS hero’s ZFS environment), giving users granular control over redundancy, performance tuning, and cache layering with non-proprietary M.2 NVMe SSDs. This openness also applies to QNAP expansion units, many of which continue to work even with completely mixed-brand storage configurations—something Synology’s newer expansion policies have started to restrict.
For users in regions where Synology-branded media is expensive, hard to find, or simply not justified for non-critical applications, this policy shift on the DS925+ can be a deal-breaker. It positions the system closer to an appliance model, where Synology controls not only the hardware and software, but the storage medium itself. While that vertical integration may improve long-term reliability for some enterprise users, it’s difficult to reconcile with the broader DIY NAS community that values choice and modularity. Ultimately, this creates a philosophical divide: QNAP remains open, modular, and adaptable, trusting users to make informed decisions about their storage media. Synology, in contrast, is consolidating control, with the DS925+ exemplifying a move toward a closed ecosystem—potentially alienating users who previously praised DSM for its balance of simplicity and flexibility. Prospective buyers need to weigh not just performance and features, but how tightly they want to be tied to a single vendor’s hardware roadmap.
Synology DS925+ vs QNAP TS-464 NAS – Which Should You Buy?
The Synology DS925+ is a 2025 refresh designed with clear intent: push performance, tighten control, and streamline the out-of-box experience. In contrast, the QNAP TS-464—released in late 2022—is a Swiss Army knife of NAS flexibility, packed with customization options, open compatibility, and enough horsepower to meet the needs of both power users and small business deployments. Choosing between them ultimately comes down to what kind of NAS experience you’re after: a controlled, polished, and tightly integrated environment, or an open, adaptable, and hardware-friendly platform. On raw performance, the DS925+ has the edge. Its quad-core, 8-thread AMD V1500B CPU delivers higher throughput for multitasking, virtual machines, and heavier concurrent services, and DSM’s user/service thresholds are notably higher as a result. Add in dual 2.5GbE ports by default, and it’s clearly a step ahead of the DS923+ predecessor 1GbE-only base configuration, and you are looking at a healthy upgrade in several ways in this refresh. However, QNAP claws back ground with its PCIe Gen3 x2 slot, allowing 10GbE upgrades, Wi-Fi cards, and even GPU acceleration in select use cases—something Synology removed entirely from the DS925+. In QNAP’s favor is also its support for real-time hardware transcoding, HDMI 2.0 video output, and direct-attached monitor access—making it a better fit for media-centric environments where local playback, Plex, or Kodi usage matters.

But perhaps the most significant dividing line is drive compatibility. The DS925+ will only initialize DSM with Synology-validated drives—locking out nearly all third-party HDDs and SSDs unless explicitly approved. This hardline stance means limited flexibility for users wanting to build using existing drives or regional market alternatives. Meanwhile, the TS-464 supports virtually all consumer and enterprise drives, from Seagate to Toshiba to Kingston, giving users total control over their storage budget and deployment roadmap. This open-ecosystem approach extends to M.2 NVMe usage too, where QNAP allows storage pool creation, caching, and tiering with off-the-shelf modules, while Synology restricts pool creation to only their branded NVMes. If you’re an IT administrator, content creator, or SMB looking for a polished, performance-forward NAS and you’re fully on board with Synology’s ecosystem—including its branded drives—then the DS925+ offers a streamlined, high-ceiling experience with excellent multitasking potential and cleaner UI/UX polish under DSM 7.2. But if you’re someone who values flexibility, upgrade paths, media support, or simply wants to control your storage choices without vendor lock-in, the QNAP TS-464 is an incredibly compelling alternative—offering strong performance for its price, an open architecture, and a deeper toolbox under QTS/QuTS Hero.

Best NAS You Can Buy Right Now (Mid-2025) for Under $499
As of mid-2025, the sub-$499 NAS market is more competitive than ever, with several brands offering systems that deliver strong hardware, dedicated operating systems, and multiple drive bays within a modest budget. For home users, prosumers, and small teams looking to centralize data, manage backups, or stream media locally, this price bracket now includes options that would have cost significantly more just a few years ago. From rackmount storage appliances to compact flash-based servers, there are now choices to suit a wide variety of workloads and network environments.
This article examines five out-of-the-box NAS systems that are currently available for $499 or less. While each system takes a slightly different approach—whether prioritizing raw bandwidth, containerization, virtualization support, or software simplicity—they all represent viable solutions for users seeking value without compromising core functionality.
Important Disclaimer and Notes Before You Buy
All of the NAS systems featured in this list are diskless, meaning they do not include storage media by default. Users will need to purchase compatible 3.5″ HDDs, 2.5″ SSDs, or M.2 NVMe drives separately depending on the system’s configuration. This significantly affects the total cost of ownership, particularly for all-flash systems where NVMe drives are required. Some devices also use onboard flash or eMMC storage to house the operating system, but this is not sufficient for general file storage. Buyers should also consider the cost of drives, RAID redundancy planning, and any accessories (e.g., cables or cooling enhancements) when budgeting for deployment.
Another consideration is the variation in NAS operating systems provided. While most models come with a vendor-specific OS—such as Synology DSM, TerraMaster TOS, UGOS, or Unraid—some platforms allow or even encourage the installation of third-party alternatives like TrueNAS or Unraid without voiding hardware warranties. However, in cases where the software stack is less mature or limited in features, users may need to invest more time configuring services such as Plex, Docker, or SMB sharing manually. As such, these systems are best suited to users who are comfortable managing basic network services or are willing to explore more advanced functionality over time.

Best NAS You Can Buy Right Now (Mid-2025) for Under $249
As personal data storage needs continue to grow in 2025, more users are seeking cost-effective alternatives to cloud services and monthly subscription platforms. Whether you’re backing up years of photos, hosting your own video library, or managing light business data locally, a dedicated NAS (Network Attached Storage) device offers greater privacy and control without recurring fees. Fortunately, the sub-$249 price point now includes a variety of surprisingly capable systems. Thanks to developments in low-power processors, DDR5 memory adoption, and more efficient operating systems, these devices can now handle everything from Plex streaming to light container workloads with relative ease. In this article, we explore five NAS solutions currently available at or below this price point, offering a balance of performance, connectivity, and storage potential for those looking to build their own storage solution on a modest budget.
Important Disclaimer and Notes Before You Buy!
Before diving into the specific NAS models, it’s important to understand the limitations and shared characteristics of devices in this price range. Most sub-$249 NAS units do not include any hard drives or SSDs, and many rely on M.2 NVMe slots or 2.5″/3.5″ SATA bays that must be populated separately. Some models ship with basic onboard storage (e.g., 32GB–64GB eMMC) sufficient only for the operating system. As such, the actual cost of getting a fully operational NAS with adequate storage for your needs may exceed the base unit price. Buyers should also be aware that these devices are best suited for home users, personal cloud use, and entry-level tasks, rather than intensive business or enterprise workloads. Additionally, several of the devices covered in this list do not come with a full-featured NAS operating system. Instead, they either rely on lightweight Linux-based platforms like CasaOS or ZimaOS, or they provide a basic UI designed for local file access and container management. While these OS options are improving in terms of user-friendliness, they may lack advanced features like comprehensive RAID management, automated snapshots, or multi-user file permission systems found in higher-end platforms like Synology DSM or TrueNAS. These NAS units are most appropriate for users with some technical confidence, or for those looking for a basic plug-and-play setup with limited customization needs.
Beelink ME Mini NAS – 6 Bay SSD NAS
$209– Intel N150 – 12GB – No SSD (64GB eMMC Only) – 2x 2.5GbE + WiFi 6 – No OS / User Install – BUY HERE
The Beelink ME Mini is a compact NAS device aimed at users who want high-speed, SSD-based storage in a minimal footprint. Measuring just 99mm on each side, it features six M.2 2280 NVMe slots, providing up to 24TB of total capacity when fully populated. Powered by the Intel N150 processor and paired with 12GB of LPDDR5 memory, it offers a decent balance between performance and energy efficiency. Connectivity is handled via dual 2.5GbE LAN ports, WiFi 6, and Bluetooth 5.2, making it suitable for both wired and wireless environments. The unit is cooled passively and contains an integrated power supply, reducing cable clutter and making it ideal for placement in home media setups or small offices.
However, the device does not include an operating system, and users will need to install a preferred NAS OS themselves — whether that’s CasaOS, Ubuntu Server, or something container-based. There’s also no bundled storage beyond the 64GB eMMC system partition, so the overall cost will rise depending on your NVMe selections. It lacks support for traditional 3.5″ or 2.5″ SATA drives, making this NAS most suitable for users seeking a quiet, SSD-only setup with strong networking performance and flexibility for custom OS installation.
The GMKTec G9 offers similar internal hardware to the Beelink ME Mini, including the same Intel N150 processor and 12GB of LPDDR5 memory, but with a more rectangular chassis and fewer SSD slots — four instead of six. The system includes 64GB of onboard eMMC storage, primarily used for booting Ubuntu 24.10, with the option to dual-boot into Windows 11 if a suitable SSD is installed. Like the Beelink, it lacks traditional SATA support and focuses on high-speed NVMe storage via M.2 2280 slots, up to 4TB per drive. The unit is cooled actively and includes dual HDMI outputs, making it more appealing for those who may want to use it as a lightweight desktop or media output device in addition to a NAS.
One of the notable differences is its broader OS support and better I/O variety, including three USB 3.2 ports and a DisplayPort-capable USB-C connector. This NAS is best suited to users looking for a more configurable or multi-purpose system with better visual output options. However, as with the Beelink, users must add their own NVMe storage, and setup requires a basic understanding of system boot configuration and OS installation. Note – this one GETS HOT, so get SSD heatsinks and ensure a good active airflow wherever you deploy it!

Unlike most NAS devices in this price range, it comes pre-configured with a 4TB internal hard drive and a sealed chassis, meaning users don’t need to source or install any storage themselves. It runs on a Realtek RTD1619B ARM-based processor, includes 1GB of DDR4 memory, and connects over a single 1GbE port. The included BeeStation Manager (BSM) OS is designed specifically for beginners, offering cloud-style file access, photo management, and mobile app integration with minimal technical effort.
This NAS is best suited to individuals or households that want a simple local backup and file-sharing solution that behaves more like a smart external hard drive than a customizable NAS. It supports basic multimedia functions, Synology mobile apps, and remote access features, but does not allow for internal expansion or RAID redundancy. The included USB-A and USB-C ports can be used for manual backups to external drives. However, because it’s a sealed single-drive unit with no RAID options, users should plan to back up to another location—either cloud or USB—to ensure data protection. Despite these limitations, its all-in-one design, 3-year warranty, and simple user experience make it one of the few truly plug-and-play NAS systems under $250.

UGREEN NASync DXP2800 NAS – The New Challenger!
$249 – Intel N100 – 8GB – No Storage (32GB eMMC) – 1x 2.5GbE – UGOS Pro – BUY HERE
The UGREEN DXP2800 is part of the company’s NASync lineup, aimed at users who want a blend of expandability and affordability. It combines the practicality of traditional HDD storage with the performance benefits of SSDs, offering two 3.5″ SATA bays alongside two M.2 NVMe SSD slots for faster caching or active data operations. At the heart of the system is an Intel N100 processor, a 12th-generation quad-core chip from Intel’s energy-efficient N-series lineup, which supports both basic virtualization and multimedia streaming. This is paired with 8GB of DDR5 memory, non-ECC but upgradable, and a 32GB eMMC used solely for the preloaded UGOS Pro operating system. Connectivity is handled through a single 2.5GbE LAN port and a mix of USB ports on both front and rear panels — including USB-C and 10Gbps-capable USB-A. UGOS Pro, while relatively new, features a clean web-based interface with container support, RAID management (0, 1, JBOD), remote file sharing, and basic multimedia services.
While it lacks the ecosystem polish of Synology DSM or QNAP QTS, it is one of the few turnkey options in this price range that supports both SSD and HDD usage in a flexible, non-proprietary layout. However, buyers should still account for the need to install their own drives and configure the storage pools manually. It’s a solid balance of raw hardware potential and modest software capability for users willing to manage their setup beyond the initial boot.
$199 – Intel N150 – 8GB – No Storage (32GB eMMC) – 2x 2.5GbE – ZimaOS – BUY HERE
The ZimaBoard 2 (832) is a low-profile, single-board NAS platform designed for flexibility and modularity rather than out-of-the-box convenience. Unlike traditional NAS systems with enclosures and tool-less drive bays, this unit is a bare embedded board that offers direct access to interfaces for those who want to build or customize their own setup. It is powered by the same Intel N150 quad-core processor used in other compact NAS systems, paired here with 8GB of LPDDR5x memory and 32GB of onboard eMMC storage for its pre-installed ZimaOS. This board features two powered SATA 3.0 ports, making it one of the few sub-$250 NAS options that supports HDDs natively without requiring USB-to-SATA adapters or expansion modules.
In terms of connectivity, the ZimaBoard 2 includes dual 2.5GbE LAN ports, USB 3.1, a PCIe 3.0 x4 slot, and a Mini DisplayPort output supporting 4K60 video. While the PCIe slot expands potential use cases (e.g., additional networking, storage, or accelerator cards), most users will opt to use the SATA ports for reliable storage first. The board is passively cooled with a large integrated heatsink and operates silently, but thermal performance may vary based on enclosure design and ambient temperature. It is particularly well-suited to DIY users looking to build a lightweight NAS, firewall, media server, or container host. ZimaOS includes a web-based UI and supports CasaOS and Linux-based OS alternatives, but configuration still requires basic familiarity with system setup and storage configuration. It’s not intended for users looking for plug-and-play simplicity, but rather those who want total control over their NAS hardware and software environment.

What Are Synology NAS Product Refreshes and What is Synology’s Logic?
When Synology introduces a new wave of NAS devices, it’s easy to assume that each new model is a significant leap forward. However, many of these launches are better classified as product refreshes, not entirely new product lines. This distinction matters. A refresh typically reuses a core hardware platform—such as the chassis, CPU, or layout—but includes modest updates like better network interfaces, more memory, or small component shifts. In 2025, Synology rolled out one of its broadest refresh cycles in years, affecting models across their two-bay, four-bay, five-bay, and eight-bay portfolios. Understanding what a refresh actually is helps users make more informed decisions, especially when evaluating whether to upgrade or wait.
Synology refreshes its products for a few practical reasons. First, component availability and pricing change over time. CPUs and other hardware elements that were once expensive or reserved for high-tier models often become more affordable, making them suitable for use in lower-tier devices. For example, the AMD V1500B processor, once exclusive to mid-tier and enterprise NAS systems, has trickled down into several 2025 refreshes like the DS925+ and DS1525+. Similarly, market-wide transitions—such as the shift from 1GbE to 2.5GbE—are reflected in these updates, allowing Synology to modernize existing models while keeping their manufacturing costs and prices relatively stable.
One of the key things that sets a refresh apart from a brand-new NAS model is Synology’s commitment to product tier consistency. Devices like the DS725+, DS425+, or DS1825+ aren’t being built to reinvent the wheel. Instead, they exist to preserve the price-to-performance balance that their predecessors established in the Synology product lineup. By holding onto the same CPU, expanding RAM slightly, and upgrading network ports from 1GbE to 2.5GbE, Synology keeps these NAS solutions within their traditional target audience—be it home users, prosumers, or small businesses. The physical design and key feature sets are familiar, and that’s deliberate. Refreshes aim to improve what already works, not redefine the category.
It’s also worth recognizing that Synology’s product refreshes are not aimed at recent buyers. If you just picked up a DS723+ or DS923+ last year, you are not the intended audience for the DS725+ or DS925+. Instead, these refreshes are aimed at users still running a DS216+, DS416, or DS1813+—users who are five to ten years deep into their existing systems. For them, the new hardware represents a meaningful leap forward, even if it looks modest on paper. When you compare a DS916+ to a DS925+, the differences in memory, CPU threads, M.2 caching, and DSM features become much more pronounced.
Pricing also plays a central role in Synology’s refresh strategy. For the most part, Synology tries to keep prices stable across generations, despite inflation and rising manufacturing costs. For example, the DS425+ and DS225+ refreshes, though modest in their hardware upgrades (mainly 2.5GbE LAN replacing 1GbE), still aim to hit the same price points as their DS423+ and DS224+ predecessors. This can make refreshes seem less appealing to new buyers comparing specs on a chart, but it serves long-term users who value Synology’s software ecosystem, consistent performance, and extended support.
One notable outlier in Synology’s refresh strategy is the continued use of the Intel Celeron J4125 processor, particularly in models like the DS425+, DS225+, and DS625slim. Despite Synology’s tendency to update hardware every 2–3 years based on market trends and component availability, the J4125—originally launched in 2019—feels increasingly outdated in 2025. Intel itself has moved away from the Celeron/J-series naming convention entirely, transitioning to more efficient and capable platforms like Alder Lake-N and N-series processors. This shift highlights just how long in the tooth the J4125 has become. With no support for newer instruction sets, lower efficiency compared to modern equivalents, and limited future compatibility, its continued presence in refreshed Synology NAS models stands in stark contrast to the broader trend of hardware advancement. While Synology has prioritized price consistency and DSM support, the persistence of this older CPU dampens the appeal of these refreshes for new buyers who expect more current internals at a similar price point.
Another important factor is Synology’s software-first development model. Their NAS hardware isn’t meant to push technical limits but rather serve as a stable, reliable platform for DSM (DiskStation Manager). That’s why even in refreshes, the focus is on compatibility and long-term support over flashy specs. Synology has made this clear through product cycles like the DS1825+, which retains the same CPU as the DS1821+ but gains 2.5GbE and better memory configuration—supporting the increasing demands of DSM applications without needing an overhaul of the entire system.
In summary, a product refresh in Synology’s ecosystem is not a groundbreaking redesign, but a thoughtful, incremental update within an established product profile. These refreshes ensure the long-term viability of key NAS tiers while adapting to evolving market standards like 2.5GbE, more demanding software workloads, or new expansion options. For long-time users, they offer an accessible upgrade path. For newcomers, they may seem underwhelming on paper. But in either case, they represent a balancing act between hardware, price, and software synergy, which has long been Synology’s model—whether you agree with it or not.

Depuis plusieurs années, Synology explore l’intégration de l’intelligence artificielle pour améliorer son service client. Si le fabricant reste discret sur ses outils internes, William Eudes (Technical Support Manager de Synology France) nous a donné un aperçu de SynoGPT, une solution de support assistée par IA utilisée exclusivement en interne…
Une IA en soutien du support, pas un remplaçant
SynoGPT est un outil basé sur les technologies de RAG (Retrieval-Augmented Generation), mêlant génération de texte et recherche dans une base documentaire. Il est utilisé depuis 2 à 3 ans en interne par le support technique de Synology, avec une montée en puissance significative depuis début 2024.
L’outil ne se connecte pas directement aux données des utilisateurs, mais repose sur une base de connaissances support (interne et publique) ainsi qu’un historique des tickets traités par le passé. La finalité est claire : proposer une réponse fiable et rapide aux demandes basiques de niveau 0.
« L’IA ne remplace pas le support, elle l’accompagne », insiste William Eudes.
Niveau 0 : l’IA prend le relais en autonomie
En moyenne, 2 000 tickets sont reçus chaque mois par le support Synology France. Environ un quart de ces tickets (de niveau 0, les demandes simples) sont aujourd’hui pris en charge par SynoGPT. Si un ticket n’est pas pris en charge par un technicien au bout de 30 minutes, l’IA envoie une réponse automatiquement, ce qui est particulièrement utile en dehors des heures ouvrées.
Depuis septembre 2024, l’envoi des réponses est automatisé après validation des suggestions de l’IA. Cela signifie que les réponses proposées par l’IA sont jugées assez fiables pour être envoyées sans relecture systématique, tout en étant toujours disponibles en interne pour évaluation.
Résultat : 60 % des clients ne rouvrent pas leur ticket après une réponse de SynoGPT, un signe fort de la pertinence de l’outil.
Si le client répond au ticket, c’est un humain qui prend la suite… en aucun cas l’IA.
Notée presque comme un humain
Chaque réponse fait l’objet d’un questionnaire de satisfaction. Selon Synology « Les réponses générées par notre IA atteignent également un niveau très proche des performances humaines, ce qui démontre l’efficacité de cette technologie en complément de notre expertise ».
En parallèle, les techniciens notent également la qualité des réponses IA une fois le ticket clôturé. Ce double mécanisme d’évaluation permet à Synology d’améliorer continuellement la pertinence des réponses générées par SynoGPT.
SynoGPT est actuellement réservé aux utilisateurs particuliers et petites structures. Les clients professionnels et grands comptes continuent de bénéficier d’un accompagnement humain complet, notamment pour les projets complexes, comme la migration d’unités de stockage – un service qui reste gratuit chez Synology.
Mon retour d’expérience
J’ai personnellement eu recours au support de Synology un dimanche, en ouvrant un ticket pour un problème technique. 30 minutes plus tard, je recevais une réponse (clairement identifiée comme générée par l’IA). À ma grande surprise, les 5 pistes proposées étaient toutes cohérentes et bien ciblées.
Dans mon cas, le problème venait finalement d’une défaillance matérielle, prise en charge dans le cadre de la garantie. Mais je dois reconnaître que l’IA a su m’aiguiller efficacement. Elle aurait probablement permis de résoudre le souci…
C’est la pertinence de la réponse, combinée au fait qu’elle provenait clairement d’une IA, qui a éveillé ma curiosité et m’a donné envie d’en savoir plus… jusqu’à provoquer ce rendez-vous avec William.
En synthèse
Avec SynoGPT, Synology montre qu’il est possible d’intégrer l’IA dans un processus de support sans déshumaniser la relation client. Loin de remplacer les équipes, l’outil automatise le traitement des demandes simples pour mieux recentrer les techniciens sur les cas complexes.
Et pour l’avoir testé moi-même, je peux confirmer : réactivité, pertinence et clarté sont bien au rendez-vous. Une belle démonstration d’une IA réellement utile…
The 45Drives HL8 is an 8-bay desktop NAS chassis developed for users who want professional-grade storage hardware without committing to the rigid ecosystems of traditional NAS vendors. Designed and manufactured in North America, the HL8 is available in several configurations, with this review focusing specifically on the chassis, backplane, and power supply model. This version includes a precision-built steel enclosure, a direct-wired 8-bay SATA backplane, and a 500W 80 Plus Gold-rated Flex ATX power supply. It omits bundled motherboards, CPUs, and pre-installed operating systems, appealing to users who prefer to build or customize their NAS hardware environment while still benefiting from an integrated power and storage foundation. The HL8 aims to bridge the gap between low-cost DIY NAS enclosures, which often suffer from poor thermals and awkward layouts, and locked-down consumer appliances that limit software choices and upgrade potential. With a hinged open-frame design, support for full-height PCIe cards, and internal layout optimized for accessibility and cooling, the HL8 is positioned as a platform for long-term use and adaptability rather than a quick-start solution. While its price point is significantly higher than generic imported chassis, its construction and modular focus suggest it’s intended for serious users seeking more control, not simply more convenience.
Who Are 45Drives?
45Drives is a Canadian storage hardware manufacturer based in Nova Scotia, operating as a division of Protocase, a custom enclosure and prototyping company. The brand has built a reputation among system integrators, IT professionals, and homelab enthusiasts for delivering modular, open-platform storage solutions. Unlike many NAS vendors that focus on vertically integrated ecosystems, 45Drives offers systems built around industry-standard components, designed to be user-serviceable and adaptable. Their catalog includes high-density rackmount systems like the Storinator, hybrid flash-HDD systems such as the Stornado, and more recently, a range of compact desktop NAS chassis under the “HL” or HomeLab label. The HL8, HL4, and HL15 models are part of this effort to scale down enterprise-grade build quality into a form factor more appropriate for deskside or small office deployment.
A core part of 45Drives’ identity is its commitment to open-source principles, not just through hardware compatibility but also in software tooling and education. The company develops and maintains Cockpit-based management modules—such as their ZFS and Samba interfaces—for Linux distributions like Rocky Linux, which they often preinstall with their systems. These modules are freely available on GitHub, and the company encourages users to modify, self-host, or adapt them as needed. In addition to their software work, 45Drives actively engages with the community through regular YouTube content, documentation portals, and technical support that continues even when customers deviate from default hardware or software configurations. This combination of enterprise durability, user empowerment, and open development has earned 45Drives a dedicated following among those who want to retain full control over their infrastructure without sacrificing reliability or support.

45Drives HL8 8-Bay MITX NAS Review – External Design
The HL8’s exterior sets it apart from typical consumer NAS enclosures through its bold and unique industrial construction – practically enterprise grade, at a homelab and desktop level. Built from 16-gauge powder-coated steel, the chassis weighs approximately 22 lbs even before drives are installed, conveying a sense of structural rigidity that clearly aligns more with enterprise hardware than with mass-market desktop cases.
The finish is matte and durable, avoiding cheap plastics or decorative panels. Buyers can choose between metal and acrylic front plates, and several color options are available, offering some degree of personalization—something rarely seen at this tier. Branding is subtle, with the HL8 model designation etched into the top panel and a logo plate on the front face.
Unlike most enclosures that rely on removable panels or sliding trays, the HL8 features a hinged “clam shell” design. The entire upper shell lifts open via captive thumb screws, granting immediate access to internal components without needing to remove the drives or disconnect cabling.
This mechanism provides real-time visibility into the system’s interior during operation, making it easier to perform diagnostics, replace fans, or adjust cabling. It’s particularly helpful for users who regularly service or upgrade their systems, and it avoids many of the frustrations associated with cramped or tool-dependent access panels.
The front of the case houses eight hot-swap 3.5” bays in a vertical arrangement, accessible without tools and pre-wired via the internal backplane. These bays are trayless and rely on drive guides for alignment, secured by the structural frame rather than individual plastic sleds. This design allows for rapid drive installation and removal while minimizing potential points of mechanical failure. The front ventilation is cut directly into the steel fascia, and airflow is directed through the drive bays by internal Noctua fans located behind them. There are no visible indicators or LCD panels on the front panel—minimalism is favored over visual clutter.
Around the rear, the layout remains conventional but clean. The rear I/O cutout accommodates standard mini-ITX motherboard layouts, and the single expansion slot supports a full-height PCIe card up to 72mm in height. The integrated Flex ATX power supply sits beside the motherboard area with its own exhaust fan, and ample passive ventilation is provided via additional steel cutouts. While visually understated, the HL8’s outer design prioritizes durability, accessibility, and functional airflow—traits that reflect its enterprise lineage more than its homelab label might suggest.

45Drives HL8 8-Bay MITX NAS Review – Internal Case Design
Internally, the HL8 case is engineered for both accessibility and structured airflow, with a layout that avoids many of the compromises found in smaller or mass-produced enclosures. The most notable feature is its fully hinged body, which allows the entire top and side panel assembly to lift upward without removing the drives. This open-access approach separates the drive chamber from the motherboard compartment without creating restrictive airflow barriers. It’s a significant advantage for users who need to inspect, troubleshoot, or upgrade internal components, especially when working with larger cooling units or dense cable configurations.
The motherboard area is positioned on the right side of the chassis, aligned horizontally to the drive plane, which prevents any obstruction by drive trays or cabling. This layout supports standard mini-ITX boards and allows full visibility of memory slots, M.2 sockets, and power headers even with drives installed. The motherboard is flanked by routing space that supports organized cabling, including SATA or power leads. This spacing is particularly useful when working with non-modular PSUs or when routing SATA cables from alternative controllers or add-in cards. The case does not limit users to any specific board vendor or layout beyond the mini-ITX size constraint.
Cabling for the backplane is pre-installed in the PSU model, which simplifies setup considerably. The backplane itself is a direct-wired design supporting up to eight SATA drives without requiring SAS expander cards or proprietary interfaces. This approach ensures compatibility with a wide range of consumer and enterprise SATA drives and avoids the long-term risks of vendor-specific drive bay lock-ins. It also makes replacing or troubleshooting individual cables far easier than in systems using multipath or bundled connectors. Power and data connections are cleanly routed through the side of the case, keeping airflow clear and minimizing vibration interference.
The Flex ATX PSU sits at the rear left and is mounted horizontally, drawing air through its own intake and exhausting separately from the main airflow path. This compact configuration leaves the bulk of the case’s lower chamber available for future expansion or airflow tuning. Additional internal fan mounts and brackets are preinstalled, and 45Drives includes all necessary mounting screws and documentation—even down to port-specific manuals for the pre-installed PSU. The internal design of the HL8 shows clear thought toward ease of maintenance and modularity, reflecting an expectation that users will revisit and modify their system over time rather than treat it as a sealed appliance.
45Drives HL8 8-Bay MITX NAS Review – Noise and Cooling
The HL8’s cooling design reflects a balance between thermal efficiency and acoustic performance, especially in its PSU-included configuration. By default, this model ships with multiple Noctua fans—specifically, two NF-A12x15 fans for intake and one NF-A4x10 for exhaust—which are widely regarded for their low noise output and long-term reliability.
Combined with the direct airflow path created by the open drive cage layout, the HL8 maintains effective cooling of both hard drives and system components without requiring high-RPM, high-noise fan profiles. Even under load, thermal tests show the drive temperatures hovering around 50°C in a 20°C ambient environment—well within safe operating margins for mechanical disks.
In real-world usage, the system produces around 33–34 dBA at idle and 42 dBA under full fan load during tasks such as ZFS pool creation or sustained disk activity. These levels are consistent with what you would expect from a quiet desktop PC and are significantly lower than typical rackmount systems or budget enclosures using unbranded high-speed fans.
The use of steel panels throughout the chassis also contributes to noise dampening, reducing vibration resonance from spinning drives. Overall, the HL8’s thermal and acoustic profile is well-suited for deployment in office or home environments where audible noise is a concern, without sacrificing long-term cooling performance.
45Drives HL8 8-Bay Case vs the Jonsbo N3 Case
The 45Drives HL8 and the Jonsbo N3 both offer 8-bay NAS enclosures for mini-ITX builds, but they cater to very different tiers of the DIY NAS market. The HL8 is positioned as a premium, enterprise-grade enclosure built entirely from 16-gauge steel and manufactured in Canada. It includes a fully integrated backplane, Noctua fans, and a Flex ATX PSU—features aimed at maximizing serviceability, thermal control, and long-term reliability.
Priced at roughly $880 USD for the chassis, backplane, and PSU combo, it targets users who demand industrial standards in a desktop form factor. The Jonsbo N3, in contrast, is a Chinese-manufactured enclosure constructed from 2.0mm aluminium alloy with 1.0mm steel internals.
It focuses on maximizing functionality in a compact and aesthetically refined format, with average retail pricing ranging between $150–$170 USD, though occasional sales and unpredictable shipping costs on platforms like AliExpress can make pricing volatile.

In terms of hardware layout and user experience, the HL8 emphasizes modularity and ease of access. Its unique “flower-style” hinged chassis allows for complete servicing of drives, motherboard, cabling, and PSU without disassembly. The built-in backplane supports both SATA and SAS, reducing the need for messy cabling or additional HBA cards unless required for scale-out. Meanwhile, the Jonsbo N3 offers a two-chamber design separating drives and the motherboard/PSU area, supporting 8 hot-swap drives via an included SATA-only backplane. However, the power delivery system relies on two Molex and one SATA connector—an odd combination that may require more planning for power distribution. The N3 also employs a PSU passthrough cable from the back to a front-mounted internal SFX PSU, saving space but potentially restricting airflow and complicating installation. Unlike the HL8’s enterprise cable routing, the N3 requires tight cable management due to its smaller internal volume, and is more prone to cable congestion near the motherboard tray.
Where the HL8 wins in build quality and professional usability, the N3 counters with surprising features at its price point. The N3 includes dual rear fans, 8 LED indicators for drive activity, USB 3.2 Gen 2 Type-C front I/O, and support for large PCIe GPUs or network cards up to 250mm. However, it uses rubber grommet-mounted drive holders instead of trays—a cost-saving measure that may reduce vibration but introduces concerns about long-term durability and ease of drive removal. It also lacks tool-less panels for the main lid, requiring an Allen key for access, which, while flush and neat, isn’t practical for regular service. By comparison, the HL8 is fully toolless throughout. Ultimately, the HL8 is ideal for users who prioritize low-maintenance reliability and modular enterprise design in a desktop form, while the N3 offers excellent value for cost-conscious DIY builders willing to trade some serviceability and airflow flexibility for size, aesthetics, and affordability.
45Drives HL8 8-Bay MITX NAS Review – The Pre-Built AMD Model
In addition to offering the HL8 as a chassis with backplane and power supply, 45Drives also sells a fully assembled, tested, and burn-in validated configuration for users who prefer a turnkey deployment. The current prebuilt model typically includes a Gigabyte B550I AORUS Pro AX mini-ITX motherboard, paired with either an AMD Ryzen 5 5500GT (6-core, 12-thread) or Ryzen 7 5700G (8-core, 16-thread) processor. These CPUs offer solid single- and multi-threaded performance, integrated graphics for transcoding or light GUI workloads, and efficient power profiles.
The build also comes with up to 64GB of DDR4 UDIMM memory, a 1TB NVMe SSD (typically Gen 4), Noctua NH-L9a-AM4 low-profile CPU cooler, and factory-installed Noctua case fans. All internal wiring is professionally routed, and the system arrives with Rocky Linux and the Houston UI preinstalled for immediate setup.

At the time of writing, the total cost of the prebuilt HL8 with the Ryzen 5700G configuration is $1,538 USD. In contrast, a self-built system using comparable off-the-shelf components can be assembled for approximately $875–$900. A rough cost breakdown would be: Ryzen 7 5700G and B550I motherboard combo ($260), 64GB DDR4 UDIMM ($103), 1TB NVMe SSD ($60), 500W Flex ATX Gold PSU ($90), Noctua CPU and case fans ($75), plus an equivalent MITX 8-bay chassis with SATA backplane ($159–$180). While this approach offers clear cost savings, it comes with multiple delivery sources, fragmented warranties, and no factory testing—factors that may be important to users prioritizing reliability and vendor accountability over price.
The prebuilt model is best suited to users who want predictable performance, reduced setup time, and consolidated post-sale support. It removes the need for component sourcing, physical assembly, and initial troubleshooting. However, it also imposes some limitations, such as the use of a single 2.5GbE network port and lack of configuration flexibility. Users requiring more advanced networking or GPU options will need to expand via the PCIe slot manually. Overall, the prebuilt HL8 fills a niche for those who want an enterprise-adjacent storage server without the learning curve or integration work required by a ground-up build, but it may be over-specified or overpriced for more self-sufficient users.
The 45Drives Houseton UI Software – Any Good?
The Houston UI platform from 45Drives is built on top of the open-source Cockpit Project, designed to offer users a web-based server management interface with a lightweight footprint.
Its browser-based GUI makes it accessible from any device on the network, and it supports multiple Linux distributions, including Rocky Linux, which is often used as the default OS with Houston UI.
One of the primary strengths of Houston UI is its ZFS management interface. Users can easily create, modify, and monitor ZFS storage pools without needing to interact directly with the command line.
The system allows for selection of RAID types (RAIDZ1, Z2, etc.), VDEV expansion, record size configuration, deduplication, encryption, and adjustable compression — all accessible within a guided, GUI-based setup.
System monitoring is a central feature of Houston UI, with a real-time dashboard showing CPU, memory, network throughput, and active services. It includes disk status indicators, smart monitoring tools, and hardware detail pages.
Some of which include visual layouts depending on motherboard detection. While the graphical presentation is basic compared to Synology DSM, it does provide sufficient system insight for regular administration.
Houston UI also includes a modular service control center, where administrators can enable or disable a wide range of server services such as Samba (SMB), NFS, SSH, and rsync.
Each module is toggleable, and users can configure individual services with editable configuration files directly from the browser. This brings flexibility, while still maintaining visual accessibility for basic tasks.
The task scheduler in Houston UI provides an easy way to set up automated jobs — including backups, updates, power cycling, and network interface toggling.
Unlike many systems that hide these functions under multiple wizards, Houston offers a unified “Tasks” area for managing all routine automations, including custom scripts and cron-based tasks.
A standout feature is the cloud synchronization and backup module, which offers connectivity to cloud platforms such as Amazon S3 and Backblaze B2, as well as support for local-to-remote rsync and FTP targets. It allows users to control bandwidth, frequency, and folder mappings from a single-pane interface — something that’s typically fragmented in competing platforms.
For users running virtual machines, Houston UI includes a KVM-based virtualization manager. This allows the creation and monitoring of guest VMs directly through the browser, including storage provisioning, image selection, CPU/memory configuration, and console access. While not as feature-rich as Proxmox, it’s suitable for lightweight VM workloads and container testing.
Finally, Houston supports module extensions, with 45Drives publishing their own file sharing and ZFS modules via GitHub. These can be installed on any compatible Linux system running Cockpit. This open approach allows users to build their own UI extensions or pull from the community, avoiding platform lock-in and enabling customization well beyond the factory defaults.
45Drives HL8 8-Bay MITX NAS Review – Verdict and Conclusion
The 45Drives HL8, when configured as a chassis with backplane and PSU, represents a refined and deliberate approach to small-form NAS deployment. Priced around $880 USD, this configuration sits well above entry-level alternatives, but the investment is clearly reflected in its enterprise-grade construction, serviceable layout, and attention to detail. With a robust 16-gauge steel chassis, direct-wired SATA backplane, and a high-efficiency 500W Flex ATX PSU pre-installed, it offers an ideal base for users who plan to build a serious and scalable NAS solution without locking themselves into restrictive ecosystems.
The hinged body design, tool-free drive access, and Noctua fan integration show a strong understanding of real-world usability, especially for those who perform ongoing maintenance, upgrades, or hardware experimentation. In that sense, it’s less a typical “consumer NAS case” and more a modular platform intended for long-term infrastructure use in homelab and small business environments.
That said, this is not a universal fit for all users. The HL8’s exclusive support for mini-ITX motherboards imposes limitations on connectivity and expansion, especially for those needing multiple PCIe lanes or additional SATA ports without relying on adapters. And while the internal layout is clearly optimized, buyers still need to be comfortable sourcing and configuring their own motherboard, CPU, memory, and storage—something that could be daunting for beginners or those seeking simplicity over flexibility. In markets where similar 8-bay enclosures from lesser-known brands can be found for half the price, the HL8’s value lies more in its physical build quality, localized production, and long-term viability rather than raw cost efficiency. Users comparing it to entry-tier rackmount gear or compact server cases will need to weigh whether the HL8’s refinement and modularity justify the premium.
Ultimately, the HL8 is a product with a clearly defined audience: self-hosters, IT professionals, and technical users who understand the value of vendor-agnostic hardware and want to retain full control over their system’s lifecycle. It offers a rare middle ground between low-cost DIY setups that require piecemeal integration and fully locked turnkey NAS systems from mainstream brands. For those who are willing to invest not only financially but also in the time and knowledge needed to assemble and manage their NAS environment, the HL8 stands out as one of the most thoughtfully engineered and supportable 8-bay NAS chassis currently on the market.

Synology vient d’annoncer leDS225+, le successeur du DS224+. Cette nouvelle version s’inscrit dans la stratégie de renouvellement de la gamme DSx25+, qui introduction enfin le 2,5 Gb/s. Toutefois, au-delà de cette amélioration réseau, les évolutions restent légères. Ce nouveau NAS justifie-t-il réellement un investissement ?
Synology DS225+ vs DS224+
Processeur et RAM = Même Combat
Les 2 NAS partagent la même architecture. Ils sont construits autour du processeur Quad Core Intel Celeron J4125 cadencé à 2,0 GHz (jusqu’à 2,7 GHz en mode Burst) et 2 Go de RAM DDR4 (non ECC), extensibles jusqu’à 6 Go.
Le processeur J4125 date un peu, mais il a fait ses preuves. Il présente l’avantage d’intégrer un iGPU (processeur graphique) Intel UHD Graphics 600, ce qui est important si vous souhaitez faire du transcodage vidéo matériel avec Plex ou Jellyfin…. On regrettera que Synology se cantonne à seulement 2 Go de mémoire vive par défaut en 2025.
Connectique
La seule vraie nouveauté de ce DS225+, c’est l’arrivée d’un port réseau 2,5 Gb/s, qui vient compléter le port 1 Gb/s déjà présent.
Cette évolution, longtemps réclamée par la communauté, permet de passer les 300 Mo/s sur un réseau compatible. Pour les transferts de gros volumes, c’est une amélioration qui se traduit par des gains de temps substantiels. C’est également particulièrement appréciable dans les environnements multi-utilisateurs.
Côté des ports USB, il n’y a aucun changement.
Politique de compatibilité plus stricte
Depuis la série DSx25+, Synology a durci sa politique de compatibilité matérielle, en particulier concernant les disques durs et SSD. Seuls les modèles estampillés Synology sont désormais officiellement supportés, excluant de fait des références pourtant bien établies sur le marché, comme les Seagate IronWolf ou les WD Red. Cette stratégie traduit une volonté claire de contrôler l’ensemble de l’écosystème afin d’optimiser les performances et la fiabilité de ses produits.

Le Synology DS225+ s’inscrit davantage dans une logique de rafraîchissement que d’une véritable révolution. L’ajout du port 2,5 Gb/s est une bonne nouvelle, qui répond aux attentes des utilisateurs.
Si vous possédez déjà un DS224+, la migration ne se justifie que dans des scénarios très spécifiques (besoin absolu de débits réseau supérieurs). Pour les nouveaux acquéreurs, le choix dépendra essentiellement de leur approche vis-à-vis de la politique de disques certifiés.
Synology DS1825+ vs DS1821+ NAS Comparison – Get It Right, FIRST TIME!
When Synology releases a new NAS in its “Plus” lineup, users often expect a blend of practical improvements, long-term support, and a reasonable upgrade path from the previous generation. The Synology DS1825+ arrives in 2025 as the official successor to the 2020/2021-released DS1821+, carrying over much of the same core design while introducing selective enhancements—and a few contentious changes. Both are 8-bay desktop NAS systems targeted at advanced home users, small businesses, and content creators who need multi-user access, flexible RAID configurations, and extensive app support. However, while the DS1821+ was praised for its broad compatibility and modular connectivity, the DS1825+ adopts a more tightly controlled hardware ecosystem. In this comparison, we break down the key differences across hardware, ports, storage capabilities, DSM software features, and drive compatibility so you can decide which model truly fits your long-term needs—without second-guessing your choice later.
Synology DS1825+ vs DS1821+ NAS Comparison – Internal Hardware
At the center of both the Synology DS1821+ and DS1825+ is the AMD Ryzen V1500B processor, a 4-core, 8-thread embedded SoC with a 64-bit architecture and a base frequency of 2.2 GHz. This chip, built on the Zen architecture, offers a balance of power efficiency and multi-threaded performance suited for environments with simultaneous multi-user file access, virtual machines, and complex RAID configurations. Synology’s decision to retain the same processor in the DS1825+ reflects confidence in its reliability and capability. However, for users hoping for a jump to Zen 2 or Zen 3-based hardware, the lack of a CPU upgrade could be a disappointment—especially considering that competing vendors have started adopting newer architectures for their mid-range systems. Still, for typical NAS tasks that do not involve on-the-fly 4K video transcoding or GPU-heavy operations, the V1500B remains a stable and effective platform with AES-NI encryption support and virtualization compatibility across VMware, Hyper-V, and Docker workloads.

The most immediate improvement in the DS1825+ over its predecessor is in the system memory. While the DS1821+ ships with 4 GB of DDR4 ECC SODIMM, the DS1825+ doubles that to 8 GB by default, giving users more overhead for running DSM services out of the box. This matters in practical terms for multitasking within Synology’s ecosystem—such as simultaneous use of Synology Drive, Surveillance Station, Virtual Machine Manager, and snapshot services. For environments where users may deploy hybrid workloads (e.g., backup automation combined with real-time collaboration tools), the extra memory in the DS1825+ reduces the likelihood of performance bottlenecks or memory swapping. Both systems support up to 32 GB (2 × 16 GB), but starting with 8 GB means many users won’t need to upgrade at all. Additionally, since both units use ECC memory, they help ensure integrity in business-critical applications by reducing silent data corruption—an especially relevant factor when hosting VMs or storing sensitive files over time.
Thermal and power characteristics between the two systems remain largely consistent, with both featuring dual 120mm fans and an internal 250W PSU that can handle full drive loads with expansion units attached. The DS1821+ and DS1825+ are also nearly identical in physical size and structure, though the newer model has a slightly higher idle noise level—23.8 dB(A) versus 22.2 dB(A)—due to denser internal configuration and possibly fan speed curve adjustments. From an operational standpoint, the DS1825+ is marginally more power-efficient in idle states, consuming just 18.34W during HDD hibernation compared to 26.18W in the DS1821+. These marginal differences suggest a refinement in system tuning, although not a radical redesign. Overall, while the DS1825+ doesn’t revolutionize internal hardware, its doubled memory and subtle optimizations give it the edge for users planning to push DSM with multiple services or those who prefer an upgrade-free deployment experience.
Synology DS1825+ vs DS1821+ NAS Comparison – Ports and Connections
One of the most tangible areas of differentiation between the DS1821+ and DS1825+ lies in their external connectivity. The older DS1821+ is equipped with four 1GbE RJ-45 LAN ports, a familiar configuration that supports link aggregation and network redundancy. This setup was common in Synology’s mid-range lineup during its 2020–2022 releases, offering a total aggregated bandwidth of up to 4Gbps—assuming your switch infrastructure supports it. For many small business users, this array of ports provided simple flexibility: you could dedicate individual ports for different services or bond them for faster file transfers. However, in practice, 1GbE is increasingly becoming a limiting factor for modern workloads, especially in environments with large raw video files, database access, or multiple users performing high-speed backups.

The DS1825+ reflects a more current networking trend by replacing the four 1GbE ports with two 2.5GbE RJ-45 ports. While this reduces the total number of interfaces, it significantly increases throughput per port, offering an aggregated maximum of 5Gbps when bonded. This shift represents a smarter allocation of bandwidth for users with 2.5GbE-capable switches or routers, and it’s more practical than the 1GbE spread seen in the DS1821+. In small office networks or prosumer setups where simultaneous data access is routine, the DS1825+ delivers higher per-connection performance, improving large file transfers and reducing latency during remote access. Though fewer in number, the newer ports provide better real-world performance potential—and users seeking higher bandwidth can still add a 10GbE or 25GbE NIC via the PCIe slot in both models.
Beyond networking, the DS1825+ introduces a notable change in expansion port design. The DS1821+ includes two eSATA ports for attaching Synology DX517 expansion units, which align with legacy expansion practices. In contrast, the DS1825+ replaces these with two USB-C-based expansion ports, designed specifically for use with the newer DX525 expansion units. While this doesn’t directly affect day-to-day operations, it signals a move toward a USB-based proprietary interface for future expansion, likely with more streamlined cabling and higher throughput potential. Additionally, the DS1825+ trims down from four USB 3.2 Gen 1 ports to three, a minor trade-off that may impact users with multiple USB-connected devices such as UPS units or backup drives. Still, for most users, the improved network and expansion standards make the DS1825+ more forward-looking, even if it reduces legacy connectivity options found on the DS1821+.
Synology DS1825+ vs DS1821+ NAS Comparison – Storage
Both the DS1821+ and DS1825+ offer eight front-facing SATA drive bays, supporting 3.5″ HDDs and 2.5″ SSDs, with hot-swappable trays for easy maintenance and upgrades. On the surface, storage capacity and configuration appear nearly identical: both models can scale up to 18 total drives using two Synology expansion units and support RAID levels including SHR, RAID 5, 6, and 10. This makes either system a viable choice for users with large datasets, whether for media, surveillance, or business-critical file hosting. However, subtle distinctions in how storage can be configured and expanded in each model make a significant difference over time.

The DS1825+ supports storage pools using its two internal M.2 NVMe slots, something the DS1821+ does not. On the older model, those slots are limited strictly to SSD caching, and even then, Synology allowed users to use third-party NVMe drives for read/write acceleration. In the DS1825+, Synology enables users to form full storage pools using M.2 SSDs—but only if those SSDs are from Synology’s own SNV3400 or SNV3410 series. This adds flexibility in theory, especially for users interested in all-flash configurations or high-speed tiers, but restricts user choice in practice. The DS1821+ offers more freedom in selecting SSDs and hard drives, with only non-blocking warning messages when using unverified models, while the DS1825+ actively blocks storage pool creation and system initialization with unlisted drives.
This tightening of compatibility extends into pool expansion, RAID rebuilds, and even hot spare assignments. In the DS1821+, users could freely mix third-party drives and expand pools over time using available or similarly specced HDDs—even those not on the official compatibility list. The DS1825+ takes a stricter approach: attempts to initialize DSM with unverified HDDs will fail, and pool expansion or RAID recovery with unsupported drives is outright blocked. While existing volumes from older NAS systems can still be migrated and booted, they will trigger persistent compatibility warnings in DSM, often with degraded system health indicators. This shift may offer Synology more control over performance validation and support consistency, but it limits flexibility for users relying on diverse or existing storage media—making the DS1821+ a better option for those with a mix-and-match approach, and the DS1825+ more suitable for fully standardized Synology deployments.
Synology DS1825+ vs DS1821+ NAS Comparison – DSM Capabilities
Both the DS1821+ and DS1825+ are powered by Synology’s DiskStation Manager (DSM) 7.2 operating system, offering access to a rich suite of applications for file management, backup, surveillance, virtualization, and cloud syncing. Core tools such as Synology Drive and Synology Photos provide a private cloud alternative to services like Google Drive or Dropbox, while packages like Hyper Backup and Active Backup for Business enable full-system and client-based data protection strategies. These services run similarly on both systems, but hardware differences can influence practical performance. For example, the DS1825+ ships with 8 GB of ECC memory by default, making it more responsive when running multiple DSM apps in parallel—such as Snapshot Replication combined with Virtual Machine Manager and Drive Client Sync. In contrast, the DS1821+ ships with 4 GB of memory, which may require an upgrade before achieving similar multitasking fluidity, especially in environments with more than a few simultaneous users.

Differences emerge in how each system handles volume structure and scaling. The DS1821+ supports up to 64 internal volumes, giving it an advantage in deployments where users need to segregate workloads—for instance, separating surveillance footage, shared team folders, user home directories, and VM storage into distinct volumes for quota management and performance tuning. This flexibility makes the DS1821+ better suited for educational institutions or small business IT teams who manage multiple user groups and need clear storage separation. The DS1825+, on the other hand, limits internal volumes to 32 but increases the maximum single-volume size to 200 TB (with 32 GB RAM installed). This makes it better aligned with large, contiguous workloads like uncompressed 4K video editing archives, security footage retention for legal compliance, or massive CAD/CAM datasets—all of which benefit more from fewer, larger volumes than from numerous smaller ones.
Service limits within DSM also subtly differentiate the two models. The DS1821+ is rated for up to 110 concurrent users in Synology Drive and Office, whereas the DS1825+ recommends a slightly lower threshold of 100 users. While the difference is marginal, it may reflect the DS1825+’s tighter memory tuning or more restrictive compatibility model, which now relies on verified Synology storage media for optimal performance. For example, in environments running Synology Office with real-time collaborative editing—paired with Drive, MailPlus, and external file sharing through WebDAV—the DS1821+ might offer more flexibility when loaded with third-party high-performance SSDs for caching. The DS1825+, restricted to Synology’s own SNV3400/3410 NVMe drives, demands tighter ecosystem compliance, which could affect responsiveness if storage performance becomes a bottleneck. Nonetheless, both models offer full support for advanced DSM modules like Synology High Availability, SAN Manager, and Hybrid Share, ensuring that users deploying in mission-critical environments still have access to the high-availability and hybrid cloud features that define Synology’s enterprise-ready platform.
Although DSM 7.2 offers the same interface and core functionality across both the DS1821+ and DS1825+, the user experience diverges notably during storage migration, particularly when using older or unverified hard drives. Users migrating existing volumes from earlier Synology systems—such as the DS918+, DS1819+, or DS920+—will find that the DS1821+ accepts those drives with minimal friction. DSM will boot normally, recognize the existing array, and issue only minor warnings in Storage Manager regarding drive verification, which are generally dismissible and do not affect functionality. RAID recovery, pool expansion, and the addition of hot spare drives all remain fully accessible, even when using third-party or previously unsupported drives. In contrast, the DS1825+ enforces stricter hardware validation: while it will mount migrated volumes, the system interface becomes saturated with persistent warning banners, amber and red health statuses, and limited drive information if the drives are not officially verified. These warnings cannot be dismissed, and attempts to rebuild RAID, add new drives to existing pools, or assign hot spares using unverified media will be blocked entirely. As a result, while both systems technically support migration, the DS1821+ offers a far more tolerant and practical transition path for users with legacy or mixed-brand storage configuration.
Synology DS1825+ vs DS1821+ NAS Comparison – Conclusion
Choosing between the Synology DS1825+ and DS1821+ comes down to whether you prioritize modern hardware refinements or broader long-term flexibility. The DS1825+ introduces subtle but meaningful upgrades: faster 2.5GbE connectivity, double the base memory, and NVMe storage pool support—features that clearly position it as the more forward-thinking choice for users committed to staying within the Synology ecosystem. However, these improvements come with tighter restrictions, most notably in its rigid drive compatibility policy. DSM cannot be installed unless only Synology-verified drives are used, and the system actively blocks unverified drives from being used in storage pools, RAID rebuilds, or even hot spare configurations. In contrast, the DS1821+ offers more freedom—supporting a wider range of HDDs and SSDs, allowing RAID recovery and expansion with non-Synology drives, and presenting a cleaner, less obstructive DSM experience when migrating from older hardware. While it may lack the newer model’s out-of-the-box performance gains, its open-ended architecture gives users—especially those with legacy drives or mixed environments—more breathing room. For users building a NAS from scratch and willing to adopt Synology’s closed hardware ecosystem, the DS1825+ is a capable and streamlined solution. But for those looking to extend the life of existing hardware or retain control over their storage media choices, the DS1821+ remains the more versatile and user-friendly option.

If Not Synology? Which Other NAS Brand Should You Choose?
It’s an odd question, but with Synology arguably making some rather higher business and enterprise decisions in recent years, there have been increasing queries about who would fill the void if they moved onwards and upwards. As Synology holds such a powerful position in the NAS market, their absence would certainly lead to quite the battle of strength from other players. The obvious answer would be QNAP, a brand that has a similar history to Synology (over two decades in the business, Taiwan-based, in-house OS, numerous 1st-party tools, home and business solutions, etc.), but in 2025, the reality is nowhere near as clear-cut. Younger established brands that have jockeyed for 3rd position, such as Asustor and Terramaster, have been challenged by several startups (ZimaCube and Zimaboard 2, Orico’s Cyberdata Vault, to name just two) entering the fray, as well as established brands like UGREEN, which are expanding their business into the NAS sector. If Synology, for whatever reason, ceased to occupy this important user class of private turnkey server ownership, who would be best placed to occupy it?
How, Where and Why Has Synology Changed?
Synology’s rapid change in business stance to be more enterprise/hyperscale-focused comes at the same time as their frequency of more entry-level, small business, prosumer, and enthusiast solutions has dropped. The regularity of smaller 2-Bay and 4-Bay solutions has noticeably decreased, and the hardware they feature has changed to accommodate more business-type use. This by no means suggests that the brand is making moves to exit these user groups (indeed, support of DSM and the latest revision DSM 7.2.2 extends to all existing users up to many systems released in the late 2010s). However, there has been plenty of user outcry from existing users and potential customers on the architecture of both DSM and the recent releases that exacerbate users to move away from the brand and spend their allocated budgets elsewhere. Synology still comfortably sits ahead of its competitors in terms of software, features, and the UX of their platform, but many changes in policy and support mentioned below have started this trend:
Changes in 3rd-party HDD compatibility on systems above the 8-Bay scale, prioritizing their own 1st-party labeled HDDs and SSDs, as well as reducing the presentation and compatibility listings on their site significantly.
Changes in the choice of internal hardware featured in their systems to be more focused on business file processes and less on multimedia use.
Comparatively smaller increases in base hardware between refreshes of individual series (e.g., J4125 and V1500B CPUs in 2024 launch devices, despite first appearing in 2019/2020).
Considerable increased focus on software enhancements over hardware (not a bad thing, but an undeniable fact).
Increased proprietary hardware support over 3rd-party (e.g., Synology-only Memory modules, custom 10GbE adapters like the E10G22-T1, Synology-only M.2 SSDs for Pool Use).
An increasing number of cloud subscription services getting newer features, while local services remain secure and stable but static.
New product focus shifting towards newer larger-scale solutions like the evolving GridStation series, Active Protect subscription system, and C2 innovations.
The predicted elimination of the J entry-level series in favor of the pre-populated and software-streamlined BeeStation.
All of the above are small factors in themselves, but add them all up, and you see small but important stepping stones toward a gear shift in Synology’s target demographic. So, if Synology were to intentionally or inadvertently begin to move outside of these user groups of home, small business, and enthusiast, who stands to fill this space and grow?
QNAP vs Synology?
As mentioned earlier, QNAP stands to be the most likely contender to fill this space. With over 20 years of history, a larger range of hardware solutions than Synology, and software that does pretty much everything Synology’s does, they have been consistent competitors. However, inconsistencies in user experience, conflicting UIs, and a tendency to try to do “too much” have resulted in their losing ground to Synology in terms of software. Add to this the negative brand impact of security incidents in 2020-2022, which tarnished their reputation around security and safety, requiring serious improvement. To the brand’s credit, they have made considerable internal culture changes on this subject, adding bounty programs, tightening system defaults, increasing pen testing, introducing several system security scanning tools, disabling things like SSH and admin super user accounts as standard, and more.
In terms of hardware, they have mostly stuck to what works, refreshing existing product families at the same rate of 2.5-3 years for desktop small-medium scale, and 3-5 years for larger scale. They have also introduced significantly more recent CPUs from both Intel and AMD, as well as 2.5GbE as standard on their solutions at the same price point as 1GbE. If it weren’t for the damaging brand harm caused by the Deadbolt/QSnatch/Qlocker ransomware attacks, I think Synology would have been significantly challenged by QNAP in the last 2-3 years across all fronts. However, the setback to QNAP’s reputation reduced this growth potential significantly, and in the last two years, we have seen an increasing number of new names pop up in NAS that have also harmed QNAP’s appeal to users in terms of hardware value, the thing they could always be relied upon to beat Synology on. QNAP would still stand to become the ‘top dog’ in the event of a Synology exit (Synexit?) from the low-to-medium tiers of NAS storage, but many new players have entered the field, such as…
UGREEN vs QNAP?
Largely known for their power adapters and PC accessories, a year ago UGREEN had practically no real presence in the world of NAS. They had a smaller scale and more entry-level range of solutions that were limited to the East, but aside from that, they were complete outsiders. Fast forward to now, and following a successful and well-marketed Kickstarter campaign that raised millions of dollars, they are now a provider of genuinely impressive turnkey NAS solutions—the NASync series. The key word there is “turnkey”, as in they are providing both the hardware and the software. They could have just rolled out their hardware and made it OS-free (i.e., “Here’s a ready-built server, now go install UnRAID or TrueNAS”), but instead, they opted to produce and include an impressively responsive NAS OS in UGOS. Genuinely challenging the feature set of the likes of Asustor and Terramaster, as well as the design of Synology and the hardware level of QNAP, UGREEN has made a rapidly growing name for itself in the small-to-medium NAS sector.
They definitely lack the range of solutions that those other brands offer, with only 6 solutions currently available (the DXP2800, DXP4800/PLUS, DXP6680, DXP8800, and DXP480T), and no rackmount solutions yet, but it’s a solid start. Equally, their software, although fluid and responsive in nailing down the NAS fundamentals, lacks many of the more impressive AAA+ solutions that are offered by the bigger brands. Lastly, although they raised a considerable sum during the crowdfunding, they do not have the global support, offices, or availability of their long-running NAS competitors—with solutions only being available in two regions, the US and Germany. All of these factors add up to a brand that is poised to make even bigger splashes in the years to come but is perhaps not quite ready to replace the big dog, Synology, just yet!
ASUSTOR vs Synology?
Always the bridesmaid, but never the bride, Asustor is a brand that has been around in the world of NAS in one shape or form for quite a few years. They are one of the mainstream Taiwanese brands in NAS that has always ‘been there’, but it is only in the last 4-5 years that they have been making sizable moves to take on both Synology and QNAP. One of the main ways in which they pursued this is by developing numerous features in both hardware and software that are available from their competitors individually. So features such as M.2 NVMe-focused storage systems, BTRFS support, WORM locking, 2.5GbE/5GbE support, HDMI output via a dedicated GUI, and more are features available on Synology and QNAP to some extent, but only Asustor rolls them under one brand umbrella. So, how poised are they to fill a void if Synology moved out of this space?
Well, from a hardware standpoint, Asustor is in a very good position. Them being Taiwan-based will certainly soothe concerns that have grown around Chinese companies and data storage solutions. Equally, their hardware has evolved rapidly in their last two generations to feature some genuinely unique solutions that are either specific to the platform or priced at a level that makes them genuinely competitive against DIY and BYO solutions. Systems such as the Flashstor series, Lockerstor series, and even value offerings like the Drivestor are surprisingly well equipped. They are not quite on the same level of hardware as QNAP (who have a significantly more diverse hardware portfolio), but they are fleshing it out very well.
However, it is the software of Asustor (ADM) that is unfortunately where the brand is a little more timid. They have a NAS OS, numerous client tools for Windows, Mac, iOS, and Android—and they nail down the bulk of the application fundamentals for storage management, multi-site backup handling, multimedia playback, containers, and more. But the platform lacks a few of the more AAA/desirable services, such as AI-powered photo recognition, a 1st-party VM tool, ZFS support, and ultimately is a little more reliant on 3rd-party applications to fill the gaps. They have recently countered this by officially detailing that they support users who buy Asustor hardware to go ahead and install 3rd-party NAS software like TrueNAS or UnRAID without it harming your warranty—so they know they are not leading the pack in terms of their own ADM NAS software but do make noticeable user concessions. With new hardware on the horizon in the Lockerstor Gen3 and Flashstor Gen2 (both of which see a significant bump in hardware profiles), we might see some impressive moves from Asustor in 2025. I just think they still have some ways to go before they can fill any potential void that Synology might leave.
TERRAMASTER vs Synology?
Terramaster has been jockeying for the NAS 3rd place spot with Asustor for well over a decade at this point, and much like their opponent, they have been good at integrating individual features from both QNAP and Synology into their own NAS hardware and TOS platform, but to a larger degree than Asustor. For example, their OS provides largely everything that Asustor ADM does (including TrueNAS/UnRAID support without voiding your warranty) but adds to this with an AI photo recognition platform, their own VM tool, and an impressive Isolation Mode that can sever the system at the click of a button from remote access, 3rd-party PHP, and any external requests (necessitating a restart to disable). However, as this brand is a Chinese brand, there will always be question marks raised by users about how this system compares with Taiwanese-based systems. This is a little unfair, given that Terramaster, Asustor, and QNAP were all successfully hit by the same ransomware attack (Deadbolt) a few years back, so there was plenty of ‘vulnerability’ to spread around!
In terms of hardware, Terramaster has been making some impressive and aggressive strides in this area—with the recent launch of their 3-part F4-424 Intel NAS series (Standard, Pro, and MAX), the release of two 8-bay M.2 NVMe 10GbE equipped systems (the F8 PLUS and F8 SSD PLUS), and new desktop and rackmounts hot on their heels. They have also scaled up the design to better improve cooling, efficiency, and just general visual appeal.
However, much like Asustor, their software is just not able to challenge the standard that Synology has set. For buyers looking for smooth and easy utilization like Synology, Terramaster’s TOS has the danger of feeling a little clunky. Their latest release, TOS6, brings new features, software standards, and design to the mix, but it lacks the range of mobile applications, desktop client tools, and consistent UX/presentation that Synology seems to do so well. Terramaster is a fantastic value-for-money choice, and I would argue they have significantly scaled up the level of hardware and software utility they provide year on year. But they still have a way to go before they can hit the same notes as Synology DSM yet.
WD / Netgear vs Synology?
This is a pretty short one! The answer is no! Both WD and Netgear have regularly reduced their hardware ranges and the frequency of software updates these last few years, and although there are a decent range of business file server systems still being released, the general home/enthusiast/prosumer level of hardware is pretty poor and uninteresting compared to everyone else on this list so far. I cannot help but get the feeling that, aside from some basic backup NAS systems that are still listed at the majority of retailers, the bulk of their range has been in circulation for 5-6 years now without any refresh in sight. For basic target file/folder storage, these systems still provide some limited modern NAS utility, but overall, they are a fairly weak alternative to Synology’s offerings in 2025.
A UniFi NAS?
With increased mentions and leaks online towards a potential NAS in the works from UniFi, this could be a very credible alternative to Synology in terms of software UX and presentation. UniFi, and its incredibly user-friendly UX featured on their Switch, Router, NVR, and Dream Machine combination systems, is where UniFi shines. No doubt any UniFi NAS solution would need to similarly blend into their ecosystem to the same degree. That said, if they were to launch a system, all their experience in the fields of network management, router security, and surveillance systems might not necessarily translate into a similar pedigree in network-attached storage. It’s hard to discuss how or if UniFi could fill any market space that a potential Synology absence would create, as they do not have any systems out in the market to make an informed decision. This is for the “To Be Continued…” pile!
Drobo vs Synology?
No…just…no. See Video Below:
IceWhale / ZimaCube
This is a very interesting one. 2023 and 2024 saw several companies arrive in the turnkey NAS space via the crowdfunding route (we already discussed UGREEN as the biggest example), wanting to break into the market. However, IceWhale benefits from having already launched two previous successfully fulfilled campaigns and is just completing their third one with the ZimaCube NAS system. Arriving with the lightweight containerized platform Zima OS (a modified version of their existing Casa OS), this new series is pretty impressive for its scale and price point at launch. Add to that the significantly unique design, impressive use of 10GbE and Thunderbolt over IP, and a 6x HDD / 4x NVMe system in a compact case, and you can see why they have made a fairly significant splash for a brand that is comparatively unheard of compared to Synology, QNAP, etc.
However, as robust as their range of solutions is (ZimaBoard, ZimaBlade, and ZimaCube), the software is still very rudimentary compared to the bulk of other browser GUI and more “operating system”-stylized UX. There are virtually no client applications, except for their own system search and connection client tools. An eventual successor to Synology, if they moved upwards toward bigger and more business-oriented solutions, would need to hit the software functionality and user experience exceedingly early and exceedingly well.
Mini PC Brands – Lincplus, Aoostar, etc.
This is an odd one. There have been a large number of solutions appearing on sites such as AliExpress that arrive as “OS-Free” services, allowing a user to get a pre-built NAS hardware solution (i.e., no need to build one yourself, which takes longer and requires a degree of technical understanding). The end user can then choose to install popular and well-established solutions like TrueNAS, UnRAID, OpenMediaVault, and more.
This serves as an impressively economical solution and has significantly grown in popularity in 2023/2024, but these 3rd-party software platforms lack a lot of the ease of use and quality of life client tools for modern devices that Synology features. Indeed, despite efforts like UnRAID 7 making its day-to-day use much easier, and TrueNAS working with HexOS for a more user-friendly output, these still pale in comparison to DSM and will also require a greater degree of technical user input in the long term to maintain stability, versus Synology’s rather more “it takes care of itself” design.
Synology vs EVERYONE ELSE – Conclusion and Verdict
If Synology were to leave the home/enthusiast/prosumer/small business tier very soon, I do think QNAP would stand to reoccupy this ground. However, give it 2-3 years, and I do think players like Terramaster, Asustor, and yes—even UGREEN—are poised to give QNAP some serious consumer competition. No doubt Synology is still keeping an eye on their competition (big and small) and would not willingly or easily give up this sector without a fight. However, there is no denying that the turnkey NAS industry is no longer the 2-3 horse race it was just five years ago!
