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.

Component Specification
CPU Intel N150 (4 cores, up to 3.6 GHz)
Memory 12GB LPDDR5
Internal Storage 64GB eMMC + 6x M.2 2280 NVMe slots

GMKTec G9 NAS – 4 Bay M.2 NAS @ The lowest Price

$185.99 – Intel N150 – 12GB – No SSD (64GB eMMC Only) – 2x 2.5GbE + WiFi 6 – Ubuntu 24.10 (Preloaded, Switchable) – BUY HERE

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!

Component Specification
CPU Intel N150 (4 cores, up to 3.6 GHz)
Memory 12GB LPDDR5
Internal Storage 64GB eMMC + 4x M.2 2280 NVMe slots
Networking 2x 2.5GbE LAN, WiFi 6, Bluetooth 5.2
Ports 3x USB 3.2, 1x Type-C (DP), 2x HDMI, Audio
OS Ubuntu 24.10 by default, dual-boot capable
Dimensions 146.6 x 100.25 x 38.75 mm


Synology BeeStation 4TB NAS – ALL IN ONE!

$199 – Realtek RTD1619B – 1GB – 4TB SINGLE BAY – 1x 1GbE – BeeStation Manager (BSM) – BUY HERE

The Synology BeeStation 4TB is a fully integrated, single-bay NAS aimed squarely at users who want a no-setup-required solution. 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.

Component Specification
CPU Realtek RTD1619B (Quad-core ARM)
Memory 1GB DDR4
Internal Storage 4TB HDD (included, sealed)
Networking 1x 1GbE LAN
Ports 1x USB-A 3.2 Gen 1, 1x USB-C 3.2 Gen 1
OS Synology BeeStation Manager (BSM)
Dimensions 148 x 62.6 x 196.3 mm


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.

Component Specification
CPU Intel N100 (4 cores, up to 3.4GHz)

Dimensions 231 x 109 x 178 mm (approx.)


ZimaBoard 2 (832 Version) – DIY Enthusiast’s DREAM!

$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.

Component Specification
CPU Intel N150 (4 cores, up to 3.6GHz)
Memory 8GB LPDDR5x
Internal Storage 32GB eMMC + 2x SATA 3.0 (powered)
Networking 2x 2.5GbE LAN
Ports 2x USB 3.1, Mini DisplayPort, PCIe 3.0 x4
OS ZimaOS (also supports CasaOS, Linux distros)
Dimensions 140 x 83 x 31 mm

 


Each of the NAS options presented here offers a different balance of hardware, expandability, and ease of use, while remaining under the $249 price threshold. Users who prefer pre-configured simplicity may lean toward the Synology BeeStation, while those seeking customization and SSD-focused performance might opt for the Beelink ME Mini or GMKTec G9. The UGREEN DXP2800 provides hybrid storage flexibility with a more developed software interface, and the ZimaBoard 2 appeals to technically inclined users who want complete control over their system stack. While no single device is perfect, all five represent viable paths toward local data ownership and self-hosted media or backup solutions without breaking the bank.

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.

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.

Dimensions (H × W × D) 166 × 343 × 243 mm 166 × 343 × 243 mm
Weight 6.0 kg 6.0 kg
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.

Port / Expansion Feature Synology DS1821+

Synology DS1825+

RJ-45 LAN Ports 4 × 1GbE 2 × 2.5GbE
Link Aggregation / Failover Yes Yes
USB Ports 4 × USB 3.2 Gen 1 3 × USB 3.2 Gen 1
Expansion Ports 2 × eSATA (for DX517) 2 × USB Type-C (for DX525)
PCIe Slot 1 × PCIe Gen3 x8 (x4 link) 1 × PCIe Gen3 x8 (x4 link)
NVMe M.2 Slots 2 × M.2 2280 (Cache only) 2 × M.2 2280 (Cache or Storage Pool, Synology-only)
Hot-swappable Drive Bays 8 × 3.5″/2.5″ SATA (Hot-swappable) 8 × 3.5″/2.5″ SATA (Hot-swappable)
Max Drive Bays (with Expansion) 18 (with 2 × DX517 via eSATA) 18 (with 2 × DX525 via USB-C)
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.

Storage Feature Synology DS1821+

Synology DS1825+

Max Single Volume Size 108 TB 200 TB (requires 32 GB RAM)
Max Internal Volumes 64 32
Supported RAID Types SHR, JBOD, RAID 0, 1, 5, 6, 10 SHR, JBOD, RAID 0, 1, 5, 6, 10
Third-Party HDD/SSD Support ✅ Fully supported (with warnings) ❌ Blocked at install/init if not verified
Storage Pool Creation with Unverified Drives ✅ Allowed ❌ Blocked
Storage Pool Expansion (Unverified Drives) ✅ Supported ❌ Blocked
RAID Recovery with Unverified Drives ✅ Supported ❌ Blocked
Hot Spare (Unverified Drives) ✅ Supported ❌ Blocked
Storage Manager Behavior (Unverified Drives) Warnings shown, but system fully functional Persistent alerts, some functions disabled
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.

DSM Feature / Capability Synology DS1821+

Hybrid Share Folder Support 10 10
High Availability Support Yes Yes
RAID Recovery (with unverified drives) ✅ Supported ❌ Blocked
Hot Spare / Expansion (unverified drives) ✅ Supported ❌ Blocked
Storage Manager (Unverified Drives) Warnings only, system fully functional Persistent alerts, functions blocked
M.2 NVMe Storage Pools ❌ Not supported ✅ Supported (Synology NVMe SSDs only)
M.2 NVMe Caching with 3rd-party SSDs ✅ Supported ❌ Blocked
Protocols Supported SMB1/2/3, NFSv3/v4, FTP, WebDAV, Rsync, iSCSI, HTTP/HTTPS, LDAP SMB1/2/3, NFSv3/v4, FTP, WebDAV, Rsync, iSCSI, HTTP/HTTPS, LDAP
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.

Synology NAS vs EVERYONE ELSE – Which Is Best?

Par : Rob Andrews
20 juin 2025 à 18:00

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!

Synology VS Terramaster NAS Drives in 2025 – Which One Deserves Your Data?

Synology and TerraMaster are two well-established brands in the network-attached storage (NAS) industry, each targeting a range of users from home enthusiasts to small and medium-sized businesses. Synology, a Taiwanese company with over two decades in the field, is widely recognized for its DSM (DiskStation Manager) software, which emphasizes stability, security, and integration within a tightly controlled ecosystem. TerraMaster, while newer to the market, has steadily gained ground by offering hardware-focused, cost-effective solutions with increasing software support via its TOS (TerraMaster Operating System) platform.

I want to provide a side-by-side comparison between Synology and TerraMaster as they stand in 2025, focusing on the real-world differences in hardware, storage, software, and security. The goal is to outline the practical strengths and weaknesses of each brand without leaning heavily toward subjective preferences or historical bias. This is especially relevant for users reevaluating Synology due to recent policy shifts, or for those considering TerraMaster as a flexible and affordable alternative.

Synology vs Terramaster NAS – Hardware Solutions Compared

When evaluating Synology’s hardware catalog, the company demonstrates a clear strategy of segmenting performance tiers through tightly integrated systems. The FS (FlashStation) series targets ultra-low latency workloads with powerful multi-core CPUs and all-flash designs. For instance, the FS6400 and FS3600 offer 240,000 and 195,000+ 4K random write IOPS respectively, built for high-throughput environments. The HD series goes a different direction, pushing density with up to 300 drives in models like the HD6500, which pair with dual 10-core CPUs and provide over 6,600 MB/s throughput. Meanwhile, the SA and XS/XS+ series address scalable performance and redundancy needs, offering dual-controller setups, high RAM ceilings, and optional Fibre Channel or 25/40GbE expansion. Synology’s Plus and Value series provide consumer-grade flexibility, but these are becoming increasingly closed ecosystems with limited hardware compatibility and optional expansion cards restricted to specific interfaces or models.

Category Synology Example Models TerraMaster Example Models CPU & RAM Range Typical Use Case
Entry-Level (2-4 Bay) DS223, DS423, DS224+, DS423+ F2-212, F4-223, F4-210 Quad-core 1.7–2.2GHz, up to 32GB ECC Personal cloud, backups, media streaming

TerraMaster, in contrast, focuses its value proposition heavily on maximizing hardware capabilities per dollar. Even in their midrange, systems like the F6-424 Max or F4-424 Pro include Intel Celeron or i3 CPUs, 2.5GbE or 10GbE connectivity, NVMe SSD support, and upgradeable RAM—all within sub-$700 price ranges. Larger units like the T12-500 Pro or U24-722-2224 scale storage up to 24 bays or beyond, while still offering competitive CPUs and abundant connectivity options. TerraMaster also maintains a vast lineup of hybrid RAID-capable DAS and NAS systems, including USB 3.2 Gen 2 enclosures for fast, direct-attached storage. Unlike Synology, TerraMaster maintains open compatibility with third-party drives and offers more consistent support for M.2 NVMe storage expansion, SSD caching, and even integrated GPU support in some models.

Overall, while Synology’s premium hardware—especially in enterprise segments like FS, HD, and SA series—is clearly capable and built with specific high-performance use cases in mind, the general direction of the brand has shifted toward tightly controlled environments with gradual upgrades. In contrast, TerraMaster’s approach offers broader hardware scalability and modularity across more price points, with emphasis on high-speed networking and expansive storage configurations. For users who prioritize full hardware utilization, third-party component compatibility, or budget scalability, TerraMaster offers more flexibility. Meanwhile, users looking for tightly integrated, support-rich systems—especially in enterprise workloads—may lean toward Synology, albeit at a higher cost per feature.

Synology vs Terramaster NAS – Storage, Compatibility and Scalability

Storage functionality is a critical part of any NAS system, and both Synology and TerraMaster offer a wide range of capabilities here—but with distinct philosophies. Synology employs its own hybrid RAID system known as Synology Hybrid RAID (SHR), which provides flexibility in mixing different drive sizes while still maintaining redundancy. SHR is available in both single- and dual-disk fault-tolerant configurations and is fully integrated with their Btrfs-based file system, offering advanced features like snapshots, deduplication, and WORM (Write Once, Read Many). Their enterprise-class devices also support more traditional RAID configurations (RAID 0/1/5/6/10) and incorporate proprietary features like Synology RAID F1 for flash endurance. However, Synology has increasingly restricted drive compatibility on newer models such as the DS925+, requiring only their own branded HAT or SAT series drives for initialization or full functionality—a move that limits storage choices for end users.

Feature Synology TerraMaster Notes
Drive Compatibility Limited to Synology-branded drives on newer models (e.g. DS925+) Open support: WD, Seagate, Toshiba, Samsung, etc. Synology enforces verified drive policy; TerraMaster is open

Storage Pool Creation via M.2 SSDs DSM 7.2+ allows with Synology-branded SSDs only TOS 5.x+ allows with most 3rd-party M.2 SSDs TerraMaster has more flexibility here
Expansion Units Proprietary only (e.g. DX517, DX525 via eSATA/USB-C) Wider variety including hybrid M.2/HDD enclosures Synology expansion limited to official units
Third-Party Expansion Enclosures Not supported or blocked in DSM Fully supported via USB or DAS TerraMaster supports open expansion ecosystem
Max Capacity (Consumer Units) Up to 180–300TB on XS+/SA series (w/ expansions) Up to 264TB+ on Pro/Enterprise systems Similar potential; depends on model
Storage Protocols iSCSI, SMB Multichannel, NFS, AFP, WebDAV iSCSI, SMB Multichannel, NFS, AFP, WebDAV Parity on protocols
Storage Analytics / Monitoring Detailed UI with health, lifespan & usage stats Less polished UI, but includes drive info & warnings Synology more user-friendly; TerraMaster more technical

TerraMaster offers a more open storage environment, supporting standard RAID types (RAID 0/1/5/6/10) and introducing its own hybrid RAID option, TRAID, designed to dynamically balance storage allocation when using mismatched drives. Like Synology, TerraMaster has implemented Btrfs in its newer systems and supports snapshots, volume encryption, and deduplication (via its Dedup Manager) across many models. However, unlike Synology, TerraMaster places no restrictions on drive brands or third-party SSDs—users are free to populate their systems with Seagate, Western Digital, Toshiba, Kingston, or Samsung drives without concern for compatibility blocks. This openness extends to M.2 NVMe support, where TerraMaster allows NVMe drives to be used not only for cache but also for primary storage pools, something Synology currently reserves for specific enterprise-class devices or limits to caching only in most consumer models.

Where Synology shines is in the management and monitoring of storage. DSM’s Storage Manager provides a clean, user-friendly interface with visualized health metrics, smart monitoring, and snapshot replication tools. Advanced features such as scheduled integrity checks, automatic repair routines, and near-seamless volume expansion contribute to its appeal in professional environments. TerraMaster’s storage UI is functional but somewhat less polished; it provides access to core tools like volume creation, SMART diagnostics, and snapshot management, but lacks some of the refined monitoring granularity found in DSM. Still, for users who prioritize freedom of storage deployment, drive variety, and full hardware utilization, TerraMaster’s openness may outweigh DSM’s slightly more mature GUI design. Ultimately, the storage advantage between the two depends on whether the user values tight software integration or broader hardware flexibility.

Synology DSM vs Terramaster TOS NAS – Software Comparison

Synology’s DSM (DiskStation Manager) remains one of the most mature NAS operating systems available today, known for its polished interface, smooth navigation, and deep integration across features. DSM offers a fully modular, desktop-like GUI accessible through a browser, with a broad suite of first-party applications such as Synology Drive for file synchronization, Hyper Backup for multi-destination backups, and Active Backup for Business, a highly regarded solution for PC, server, and VM backups.

These tools often match or exceed the capabilities of dedicated commercial backup solutions. DSM also includes native virtualization (Virtual Machine Manager), Docker container support, surveillance management (Surveillance Station), and numerous file-sharing services including WebDAV, FTP, iSCSI, and SMB multi-channel. Overall, DSM’s ecosystem is not just well-developed—it is increasingly self-contained, with Synology focusing on reducing third-party dependencies by developing in-house alternatives for productivity, security, and media apps.

 TerraMaster’s TOS (TerraMaster Operating System), currently in version 5.1 with version 6 available on select systems, has seen rapid growth in capabilities and usability over the last few years. While it doesn’t yet match DSM’s polish, it has made significant strides in offering equivalent functionality. TOS supports Btrfs-based snapshots, Rsync and CloudSync for cloud backup, Docker container deployment, and VirtualBox-based virtualization. While the latter is less tightly integrated than Synology’s VMM, it does allow for third-party VM deployment in a usable way.

TerraMaster has also developed TerraSync, a synchronization tool designed to rival Synology Drive, and supports both media management and AI-enhanced photo sorting with apps like Terra Photos. However, many of TOS’s functions rely more heavily on community-driven or open-source third-party applications, resulting in a slightly less unified experience overall.

In terms of application ecosystems, Synology’s App Center clearly offers the broader and deeper catalog, particularly for business users. First-party applications such as Synology Office, Chat, MailPlus, and Note Station deliver a productivity-focused alternative to cloud services, and their Surveillance Station software stands out as one of the most powerful NVR platforms in the NAS market.

TerraMaster’s App Center includes essential tools but lacks the same level of first-party development. However, it makes up for this in openness: TerraMaster supports a wide array of third-party and open-source platforms more freely, including Jellyfin and Unraid. Moreover, TerraMaster allows alternative operating systems like TrueNAS to be installed without voiding the warranty, which adds considerable flexibility for tech-savvy users. Overall, Synology delivers a more unified and polished software experience, while TerraMaster emphasizes adaptability, freedom, and cost

Synology vs Terramaster NAS – Security and Safety

Synology has long maintained a strong reputation in the NAS sector for prioritizing system security, and this is evident in how thoroughly security is integrated throughout DSM. Synology’s Security Advisor provides active scanning for vulnerabilities, misconfigurations, and password weaknesses, while its firewall, account protection, and IP auto-blocking features offer practical layers of defense against unauthorized access. Synology also supports comprehensive SSL certificate management via Let’s Encrypt and offers two-factor authentication (2FA) with TOTP and hardware key support. From a business continuity perspective, DSM includes native WORM (Write Once Read Many) capabilities and encrypted shared folders to protect sensitive data from tampering or deletion. Perhaps most critically, Synology operates a dedicated PSIRT (Product Security Incident Response Team), frequently publishes security advisories, and participates in high-profile vulnerability testing events like Pwn2Own—demonstrating a serious commitment to vulnerability discovery and remediation.

TerraMaster’s security offering has become more robust over recent years, particularly with the development of Isolation Mode—a unique feature allowing users to instantly sever all external access and remote services with a single click. This acts as a kill switch in the event of a suspected breach or malware event. TOS also includes a system-level security scanner that checks for basic vulnerabilities and enables 2FA, SSH restrictions, and SSL certificate deployment. While TerraMaster’s platform does not offer as many granular policy tools as DSM, it supports core protocols like OpenVPN and L2TP for secure remote access and regularly issues firmware updates in response to new threats. The company also now provides greater transparency regarding CVEs (Common Vulnerabilities and Exposures), though its advisory frequency and scope remain smaller than Synology’s.

Security Feature Synology DSM TerraMaster TOS Notes
System Hardening Proactive hardening (limited root access, secure defaults) Moderately hardened; more configurable access Synology limits risky configurations by design
Security Scanner Built-in DSM Security Advisor with customizable scan depth TOS Security Center (less detailed on TOS 5.x) Synology provides more actionable alerts

Isolation Mode / Kill Switch ❌ Not available ✅ Isolation Mode disables all external access with one click Advantage: TerraMaster for emergency lockdowns
Vulnerability Response (PSIRT) Dedicated PSIRT, public advisories updated monthly Less frequent disclosure, fewer details published Synology actively discloses and patches
Security Bug Bounty Program ✅ Yes – active white-hat reward program ❌ No public bounty program known Synology engages with global researchers
Third-Party App Restrictions Limited for security; sandboxed services More open but requires user discretion Synology prioritizes closed ecosystem safety
Remote Access Protection QuickConnect includes traffic relay + DDNS + 2FA TNAS.online DDNS with isolation toggle Both offer encrypted remote access, but Synology uses multiple layers
Malware Detection Real-time malware scanner, browser warnings Included scanner, but simpler in scope DSM scanner is more active and integrated
Backup Verification Integrity verification in Active Backup TerraSync + cloud/USB support (manual checks) DSM offers automated backup health reports
Surveillance Hardening Encrypted video storage + HTTPS + IP blocklist Surveillance App with HTTPS, still evolving Synology Surveillance Station is more mature and secure
Ransomware History 2014 “SynoLocker” (quickly patched) 2021–22 “Deadbolt” attacks (multiple waves) TerraMaster more affected in recent years
Update Frequency Frequent monthly patches Less frequent, varies by model DSM has a consistent schedule and transparency

Despite these advancements, TerraMaster’s security record has faced scrutiny in the past due to incidents like the Deadbolt ransomware attacks. These incidents, which also affected other NAS vendors, prompted significant user backlash and a push for more proactive security updates and faster patching. TerraMaster has since responded by improving software integrity and introducing layered protection features, but the lingering perception remains that Synology maintains a stronger and more proactive security posture overall.

This perception is reinforced by Synology’s investment in ongoing vulnerability research, bug bounty programs, and a broader portfolio of security-focused tools. As it stands in 2025, Synology continues to lead in NAS security maturity, while TerraMaster has made meaningful progress—especially with unique features like Isolation Mode—but still has ground to cover in enterprise-level protections and threat response.

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

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

Synology vs QNAP NAS – Hardware Comparison

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

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

Synology vs QNAP NAS – Storage Services and Scalability 

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

  SERVICE SYNOLOGY QNAP Notes
File Services SMB, AFP, NFS ✅ ✅ Cross-platform sharing
WebDAV ✅ ✅ Remote access
FTP/FTPS ✅ ✅ Standard protocols
Rsync/Remote Sync ✅ ✅ Sync across systems

Encryption (AES-256) ✅ ✅ Volume/folder-level encryption
Backup & Sync Hyper Backup / HBS3 ✅ (Hyper Backup) ✅ (Hybrid Backup Sync 3) Functionally equivalent
Active Backup for Business ✅ ❌ Enterprise-grade backup (free)
Snapshot Replication ✅ ✅ Data versioning support
Cloud Sync ✅ ✅ Multi-cloud sync integration

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

Synology DSM vs QNAP QTS/QuTS  – Software Compared

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

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

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

Synology vs QNAP NAS – Security 

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

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

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

Synology vs QNAP NAS – Price Point and Value 

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

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

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

Synology vs QNAP NAS – Conclusion and Verdict 

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

Synology PS Series Managed 10GbE PoE Network Switches Revealed

Par : Rob Andrews
26 mai 2025 à 10:00

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

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

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

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

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

Synology PS2600+ 26 Port L2+ Managed PoE Switch

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

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

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

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

Synology PS1000+ 10 Port L2+ Managed PoE Switch

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

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

Synology PS Series Switches, Conclusion and Verdict

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

The Synology RS2825RP+ Rackstation NAS Revealed

Par : Rob Andrews
22 mai 2025 à 09:00

Synology Launches RS2825RP+ RackStation NAS for Business Deployments

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

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

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

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

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

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

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

Synology RS2825RP+ vs RS2821RP+ – A Significant Upgrade?

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

Category RS2825RP+ RS2821RP+
CPU Model AMD Ryzen V1780B (4-core, 3.35 GHz base / 3.6 GHz boost) AMD Ryzen V1500B (4-core, 2.2 GHz)

Warranty 3 years (extendable to 5 years) 3 years (extendable to 5 years)

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

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

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

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

The Synology DS425+ NAS Revealed

Par : Rob Andrews
21 mai 2025 à 11:00

Synology DS425+ NAS Revealed

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

Synology DS425+ Hardware Specifications

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

Component Specification
CPU Intel Celeron J4125, 4-core, 2.0 GHz (base) / 2.7 GHz (turbo)
Memory (Default) 2 GB DDR4 non-ECC
Memory (Max) 6 GB (2 GB onboard + 1x SO-DIMM slot up to 4 GB)
Drive Bays 4 × 3.5″/2.5″ SATA HDD/SSD (hot-swappable)
M.2 NVMe Slots 2 × M.2 2280 NVMe SSD (for Synology SSDs only – cache or storage pool)
LAN Ports 1 × 2.5GbE RJ-45, 1 × 1GbE RJ-45
USB Ports 2 × USB 3.2 Gen 1
Maximum Raw Capacity Up to 80 TB (4 × 20 TB drives)
RAID Support SHR, Basic, JBOD, RAID 0, 1, 5, 6, 10
Cooling 2 × 92 mm fans
Power Supply External 90W AC adapter
Power Consumption 28.3W (Access), 8.45W (HDD Hibernation)
Dimensions 166 mm × 199 mm × 223 mm
Weight 2.18 kg
Noise Level 19.8 dB(A)
Warranty 3 years (extendable to 5 years in select regions)
Drive Compatibility Synology-verified drives only (HAT3300, HAT5300, SNV3400, etc.)

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

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

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

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

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

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

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

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

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

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

Synology DS425+ NAS – Software and Services

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

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

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

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

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

Synology DS425+ NAS – Price and Release Date

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

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

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

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

PAS7700 – Flagship NVMe Enterprise Rackmount Storage

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

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

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

PAS7700 Specifications

Feature Details
Architecture Dual-controller, active-active
CPU AMD EPYC (per controller)
Memory Up to 1TB DDR4 ECC (per controller)

PAS3600 – Hybrid Flash Storage for Cost-Efficient Deployment

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

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

DVA7400 – AI-Powered Surveillance Rackmount System

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

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

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

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

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

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

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

DS725+ Specifications

Feature Details
CPU AMD Ryzen R1600 (2C/4T)
Memory 4GB DDR4 ECC (expandable)

DS425+ – 4-Bay Multimedia NAS with Modest Refresh

The DS425+ is the 2025 refresh of the DS423+, aimed at SOHO and multimedia users seeking a 4-bay system with enhanced network throughput and M.2 NVMe support. Internally, the DS425+ continues to use the Intel Celeron J4125, a quad-core processor with integrated graphics, and comes with 4GB of DDR4 non-ECC memory. This model includes two Ethernet ports1x 2.5GbE and 1x 1GbE—a somewhat disappointing choice that limits link aggregation potential and overall throughput compared to systems offering dual 2.5GbE.

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

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

DS425+ Specifications

Feature Details
CPU Intel Celeron J4125 (4 cores, 4 threads)
Memory 4GB DDR4 (non-ECC, upgradable)
Drive Bays 4 x 3.5″/2.5″ SATA

It upgrades the CPU from the DS1522+ by moving from the AMD Ryzen R1600 (2C/4T) to the AMD Ryzen V1500B, a 4-core, 8-thread processor that previously powered the DS1621+ and DS1821+. The system comes pre-installed with 8GB of DDR4 ECC memory, double that of its predecessor.

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

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

SNV5420 – Enterprise NVMe SSD for Sustained Caching Workloads

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

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

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

20 mai 2025 à 14:53

Synology DS725+ Expandable 2-Bay NAS Revealed

The Synology DS725+ enters the scene as part of the company’s 2025 refresh to its Plus Series lineup, targeting power users, small businesses, and edge deployments that require compact, capable storage solutions without stepping into rackmount or enterprise territory. As a successor to the DS723+, it introduces several meaningful updates that improve the system’s usability right out of the box—most notably, a doubling of base memory to 4 GB ECC DDR4 (up from 2 GB) and the inclusion of a 2.5GbE LAN port for significantly faster network transfers, especially when working with high-resolution media or syncing large datasets across offices. These improvements make it immediately better suited for modern hybrid cloud workflows via Synology Drive, smoother multi-user access in Synology Photos and Office, and more responsive local performance in Surveillance Station environments. However, these upgrades come with trade-offs: the CPU remains unchanged, using the same AMD Ryzen R1600 found in the DS723+, and the PCIe slot has been removed, eliminating the popular option to upgrade to 10GbE networking or install additional specialized cards. As a result, while the DS725+ simplifies connectivity by offering faster speeds upfront, it also enforces a more rigid hardware configuration. It’s a device clearly designed with platform consistency and managed environments in mind—particularly when paired with Synology’s increasingly closed ecosystem of verified drives and accessories. For those already aligned with Synology’s ecosystem, the DS725+ offers a stable and streamlined solution for private cloud deployment that is more about ability than base storage – but with the option to add more later, collaborative data workflows, and secure backup environments. But does it deserve your data? Let’s discuss.

Synology DS725+ NAS – Hardware Specifications

The DS725+ is powered by the same dual-core AMD Ryzen R1600 processor found in its predecessor, the DS723+. This chip runs at a base clock of 2.6 GHz with a boost up to 3.1 GHz and supports hardware encryption acceleration, making it capable of handling simultaneous services like encrypted file access, Synology Drive syncing, and light virtual machine workloads. While it’s a competent processor for this class of NAS, its reuse in the DS725+ may be seen as a missed opportunity for users who were hoping for a newer or more power-efficient generation—particularly with rising expectations around AI-powered indexing and multimedia transcoding. That said, DSM 7.2’s core apps like Hyper Backup, Snapshot Replication, and Active Backup Suite remain well within the CPU’s performance envelope, ensuring reliable day-to-day operations for home offices and remote workers.

Category Specification
CPU AMD Ryzen R1600 (2-core, 2.6 GHz base / 3.1 GHz turbo)
Hardware Encryption Yes
System Memory (Default) 4 GB DDR4 ECC SODIMM (1 × 4 GB)
Maximum Memory 32 GB (2 × 16 GB)
Memory Slots 2 × SODIMM slots
Drive Bays 2 × 3.5″/2.5″ SATA (hot-swappable)
M.2 NVMe Slots 2 × M.2 2280 NVMe SSD (Synology-verified only; for cache or storage pool)
Max Drive Bays (with Expansion) 7 (with 1 × DX525 expansion unit via USB-C)
RAID Support SHR, Basic, JBOD, RAID 0, 1; RAID 5/6/10 with expansion
LAN Ports 1 × 2.5GbE RJ-45, 1 × 1GbE RJ-45

Warranty 3 years (extendable to 5 years with Extended Warranty Plus in select regions)
Drive Compatibility Synology-verified drives only (HAT3300/5300, SAT5200, SNV3400, etc.)

Where the DS725+ makes a clear improvement is in memory. Unlike the DS723+, which shipped with 2 GB of ECC RAM, the DS725+ doubles the default capacity to 4 GB ECC DDR4, offering more breathing room for multitasking, container workloads, and collaborative apps like Synology Office and Chat. This is particularly helpful for deployments using packages such as Synology MailPlus or managing multiple Surveillance Station camera streams. The RAM is installed in one of two available SODIMM slots, and the unit officially supports up to 32 GB (16 GB x2), making it suitable for heavier use cases like running multiple virtual DSM instances or handling extensive indexing operations in Synology Photos. ECC memory, while not strictly essential for all users, adds a layer of data integrity that reinforces the DS725+’s suitability for professional and production environments.

In terms of connectivity, the DS725+ makes a decisive shift by replacing the DS723+’s dual 1GbE ports with a more modern setup: one 2.5GbE and one 1GbE port. This move improves real-world transfer speeds out of the box without requiring a PCIe network upgrade, as was previously necessary. However, it also reflects a deliberate limitation: the PCIe Gen3 x2 slot from the DS723+ is no longer present, meaning users cannot add a 10GbE NIC or other expansion cards. Storage-wise, the DS725+ retains the same 2-bay SATA layout, supports hot-swappable 3.5″/2.5″ drives, and introduces M.2 NVMe SSD slots that allow Synology-branded SSDs to be used not just for caching but also for primary storage pools. Users can expand total storage to 7 drives via the DX525 USB-C expansion unit, and cooling is handled by a single 92mm fan in the rear. Power draw remains low, with a 90W adapter and idle consumption under 9W, keeping it efficient for always-on deployment.

Synology DS725+ vs DS723+ NAS – Much of an Upgrade?

At a glance, the DS725+ and DS723+ appear to be cut from the same mold. They share the same AMD Ryzen R1600 dual-core processor, identical physical dimensions, drive bay count, and expansion potential via an optional five-bay unit. However, the DS725+ makes several deliberate design changes aimed at improving out-of-the-box usability, while also signaling a shift toward Synology’s 2025 platform philosophy. Chief among these changes is the inclusion of a 2.5GbE LAN port, replacing one of the two 1GbE ports found on the DS723+. This upgrade allows users to immediately take advantage of higher bandwidth for file transfers, especially useful for larger datasets handled through Synology Drive or multimedia libraries accessed via SMB. At the same time, the DS725+ sheds the DS723+’s PCIe Gen3 x2 expansion slot, which means users no longer have the option to add a 10GbE NIC or other cards. For users needing maximum future-proofing or high-throughput workloads, this loss may feel restrictive.

Drive Compatibility Broad third-party support (with warnings) Synology-verified drives only DS725+ enforces strict hardware lock-in
Warranty 3 years (extendable to 5 years) 3 years (extendable to 5 years) Same

Another key improvement is in system memory. The DS725+ comes with 4 GB of ECC DDR4 RAM pre-installed, doubling the 2 GB included with the DS723+. This seemingly modest upgrade has real-world implications. Services like Synology Photos, which require more memory for AI-driven facial and object recognition, or Synology Office, which handles collaborative document editing, benefit directly from the added RAM—making the system more responsive and able to support more concurrent users from the outset. For users running multiple applications, hosting virtual DSMs, or leveraging Hyper Backup with compression and deduplication, the DS725+ delivers a more capable base configuration without requiring immediate memory expansion. Both systems support upgrades up to 32 GB, but the DS725+ gives a head start where it matters.

However, the most controversial difference between these two models lies in drive compatibility. The DS723+ was among the last in Synology’s lineup to offer relatively open support for third-party drives—with warning banners but no functional blocks in DSM. The DS725+, by contrast, fully embraces Synology’s walled-garden storage policy. Users must use Synology-verified drives (such as HAT3300/5300 HDDs and SNV3400 SSDs) for core operations like DSM installation, volume creation, and RAID rebuilds. While migrated pools using unverified drives may still mount with warnings, new deployments and expansions are effectively locked down. This shift reflects Synology’s strategy to control hardware variables for improved stability and long-term support—but it’s also a clear trade-off in flexibility and total cost, especially for existing users with stockpiled third-party drives from trusted vendors like Seagate or WD.

Synology DS725+ NAS DSM Software & Services

Like all current-generation DiskStation models, the DS725+ runs on Synology DiskStation Manager (DSM) 7.2, a mature, Linux-based operating system that delivers one of the most refined NAS user experiences available today. DSM combines consumer-friendly accessibility with enterprise-ready tools, making the DS725+ suitable for a wide range of use cases—from personal media libraries to business-critical collaboration environments.

Core services such as Synology Drive transform the DS725+ into a fully private cloud, enabling real-time file syncing across devices and platforms, granular access permissions, file versioning, and web-based document previews. The system can support up to 50 Drive users and half a million hosted files, making it a capable solution for small teams managing shared datasets or projects. Meanwhile, Synology Photos leverages the upgraded system memory to provide intelligent media organization, with facial and object recognition that improves as additional photos are indexed—an increasingly valuable feature in creative or archival workflows.

For data protection and business continuity, the DS725+ supports Synology’s comprehensive backup ecosystem. Active Backup Suite consolidates backup tasks for Windows and Linux endpoints, VMware and Hyper-V virtual machines, and Microsoft 365 or Google Workspace SaaS accounts. Administrators can automate tasks, monitor statuses from a unified console, and execute bare-metal recovery when needed.

Complementing this is Hyper Backup, which allows multi-destination backups—ranging from local USB storage to other NAS units, rsync targets, or Synology C2 Storage. The inclusion of Snapshot Replication provides near-instantaneous versioned recovery with 128 snapshots per shared folder and 256 per system, ensuring protection against data corruption, ransomware, or accidental deletion. These tools can be used together to create a robust, layered protection strategy even in a small-scale deployment.

Beyond file management and backup, DSM turns the DS725+ into a complete digital operations hub. With Synology Office, users can co-author documents, spreadsheets, and presentations in real time within a browser—ideal for small teams replacing Google Workspace or Microsoft 365 with a private alternative. Communication tools like Synology Chat and MailPlus offer encrypted messaging and a scalable private email server with support for up to 60 users (5 free accounts included).

For security-conscious setups or compliance-driven environments, these services operate entirely within your NAS, without relying on third-party cloud platforms. Meanwhile, Surveillance Station allows the DS725+ to manage up to 40 IP cameras at 1080p (H.265) with license-free recording for two channels, making it a competent choice for office or home surveillance when paired with Synology’s mobile and desktop apps. DSM’s inclusion of Adaptive Multi-Factor Authentication (AMFA), Active Insight fleet monitoring, and SSL/TLS support ensures that even this compact 2-bay NAS delivers serious administrative and security capabilities.

Synology DS725+ NAS Release and Price

The Synology DS725+ is set for a phased global release, with initial availability rolling out across Eastern markets—including Japan, Taiwan, China, and Australia—in late May 2025, followed by a wider international launch in June 2025. While Synology has yet to publish official retail pricing, the DS725+ is expected to arrive in line with its predecessor, the DS723+, placing it in the $449 to $499 USD range. This positions the DS725+ in the upper tier of the compact 2-bay NAS segment, offering a blend of business-capable performance and centralized storage management for prosumers, remote workers, and small teams.

Although its specifications remain similar to the DS723+ in some areas—particularly with regard to the CPU—the DS725+ includes default features like 2.5GbE networking and higher base memory, which previously required add-ons or manual upgrades. These improvements may appeal to users who want a more capable system straight out of the box without needing to invest in additional hardware. However, buyers should also be aware of the tightened hardware compatibility policy introduced across Synology’s 2025 product line. As with other new-generation models, the DS725+ requires Synology-verified drives for key operations such as DSM installation, volume creation, and SSD caching, which could impact overall system cost and drive choice flexibility.

Given these factors, the DS725+ is best suited for users seeking a stable, tightly integrated NAS experience with long-term software support and advanced functionality provided through DSM. While those with existing third-party drives may need to consider compatibility constraints, the DS725+ still represents a focused and modernized solution in the 2-bay NAS category—particularly for those fully aligned with Synology’s expanding ecosystem.

Synology Beestation Plus 8TB Revealed and Detailed

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

Synology Beestation Plus 8TB – Who Is This For?

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

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

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

Synology Beestation Plus 8TB – Hardware Specifications

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

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

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

Synology Beestation Plus 8TB – BSM Software and Services

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

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

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

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

Compared to the more advanced DS224+, the BeeStation Plus trades flexibility for simplicity. While both use the same Intel J4125 processor, the DS224+ features dual drive bays, 2GB expandable RAM, dual LAN ports, and full access to DSM 7.2, allowing users to configure RAID arrays, run Docker containers, and install Synology’s broader suite of productivity and surveillance apps. However, this comes with added complexity and a higher price tag—typically over $498 USD with equivalent storage. BeeStation Plus instead offers a fixed hardware environment, a tailored software suite, and a frictionless onboarding process that requires no knowledge of storage pools or networking. It’s aimed at users who want a cloud-like experience with full data ownership, whereas the DS224+ is intended for tech-savvy individuals or small businesses that require customizability, scalability, and integration into broader workflows.

Synology Beestation Plus 8TB – Pricing and Release

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

Synology PAS7700 NVMe NAS System

Par : Rob Andrews
14 mai 2025 à 18:00

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

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

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

Synology PAS7700 Hardware Specifications

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

Component Details
Form Factor 4U Rackmount (Dual-node, 2U per node)
Node Architecture Active-Active
CPU (per node) AMD EPYC, 24 Cores
Memory (per node) 64GB DDR4 ECC (Upgradeable to 1TB)
Memory Protection Cache Protection (battery or supercapacitor-based, unconfirmed)
Drive Bays 48 x NVMe (U.2/U.3) total, 24 per node
Drive Interfaces PCIe Gen4 via native AMD EPYC lanes and ASMedia PCIe controller
Networking (per node) 1 x 1GbE Management Port (Copper), 2 x 10GbE Aquantia Ports
Expansion Options Potential PCIe/OCPI slots for additional NICs (details pending)
Chassis Dimensions TBD (Full 4U dual-node chassis, likely hot-swappable)
Power Supply Redundant PSU (assumed, not yet confirmed)
Cooling Enterprise-grade cooling (multi-fan array; details TBD)

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

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

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

Synology PAS7700 Services and Flash Protocols

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

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

  • NFS RDMA (Remote Direct Memory Access):

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

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

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

  • NVMe-TCP (NVMe over TCP/IP):

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

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

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

  • NVMe-FC (NVMe over Fibre Channel):

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

    • Suitable for enterprises already using Fibre Channel SANs.

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

  • NVMe/RoCE (RDMA over Converged Ethernet):

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

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

    • Requires a compatible network fabric with lossless Ethernet configuration.

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

Synology PAS7700 Failover and Redundancy

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

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

  • Protocols:

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

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

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

  • Networking:

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

  • System-Level:

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

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

  • Memory:

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

  • Storage:

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

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

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

Par : Rob Andrews
7 mai 2025 à 09:37

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

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

Synology DS1825+ NAS – Hardware Specifications

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

Component Specification
CPU AMD Ryzen V1500B (4-core, 64-bit, 2.2 GHz)
Memory (Pre-installed) 8 GB DDR4 ECC SODIMM (1 × 8 GB)
Memory (Max Capacity) 32 GB (2 × 16 GB)
Drive Bays 8 × 3.5″/2.5″ SATA HDD/SSD (Hot-swappable, except M.2)
M.2 NVMe Slots 2 × M.2 2280 NVMe SSD (for caching or storage pools, Synology drives only)
Max Drive Bays (with Expansion) 18 (with 2 × DX525 via USB-C)
LAN Ports 2 × 2.5GbE RJ-45 (Link Aggregation / Failover supported)
USB Ports 3 × USB 3.2 Gen 1
Expansion Ports 2 × USB Type-C (for DX525 expansion units)
PCIe Slot 1 × PCIe Gen3 x8 (x4 link)
Cooling 2 × 120 mm fans (user-replaceable; Full-Speed, Cool, Quiet modes)
Power Supply Internal 250W PSU
Power Consumption 60.1W (Access) / 18.34W (HDD Hibernation)
Noise Level 23.8 dB(A) (Idle with Synology drives)
Dimensions (H × W × D) 166 mm × 343 mm × 243 mm
Weight 6.0 kg
Operating Temperature 0°C to 40°C
Drive Compatibility Only Synology-verified HDDs and SSDs supported for full functionality
In terms of connectivity and expansion, the DS1825+ introduces two 2.5GbE RJ-45 LAN ports, replacing the older model’s four 1GbE ports. This change offers significantly higher throughput potential out of the box, particularly for multi-user environments or those running link aggregation. For further scalability, the unit includes one PCIe Gen3 x8 slot (x4 link), which supports 10GbE or 25GbE network interface cards. Additionally, Synology has swapped out the traditional eSATA expansion ports in favor of two USB-C-based connectors, used to link up to two DX525 expansion units, increasing total drive support to 18 bays.
Drive flexibility is offered through eight 3.5”/2.5” SATA drive bays and two M.2 2280 NVMe slots for SSD caching or storage pools – though we will return to the subject of just how flexible drives are in this system in a wee bit. The NVMe slots are not hot-swappable and are positioned internally, but provide a route for improving IOPS performance. Two 120mm fans handle cooling with configurable profiles, and the system operates at an idle noise level of 23.8 dB(A), slightly louder than the DS1821+ but still relatively quiet for an 8-bay desktop NAS. The DS1825+ also retains a 250W power supply, with typical access power consumption rated at 60.1W.

Synology DS1825+ NAS – DSM Software Specifications

The DS1825+ runs Synology’s DiskStation Manager (DSM), a Linux-based operating system that brings a wide array of software features designed for both home and business environments.

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

Synology DS1825+ NAS vs the DS1821+ NAS

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

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

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

Synology DS1825+ NAS – Hard Drive Compatibility

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

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

Storage Manager Alerts – Non-Verified Drives ⚠ Warnings, dismissible 🔴 Persistent, cannot be cleared
Overall Compatibility Flexibility ✅ High – mix-and-match drives allowed ❌ Low – walled-garden enforcement

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

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

Synology DS1825+ NAS – Price and Release

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

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

UniFi UNAS Pro – SIX MONTHS LATER

Par : Rob Andrews

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

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

UniFi UNAS Pro 6 Months Later – The TL;DR

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

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

  • Enabled OneDrive and Dropbox as new cloud backup destinations.

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

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

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

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

  • Support file generation now available for diagnostics.

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

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

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

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

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

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

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


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


Synology vs UGREEN NAS Hardware Compared 

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

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


Synology DSM vs UGREEN UGOS NAS Software & Services

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

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

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

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

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


Software Comparison

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

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

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

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


Synology vs UGREEN NAS – Security 

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

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

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

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

Synology vs UGREEN NAS – Pricing and Value 

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

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


Synology vs UGREEN NAS – Verdict & Conclusion

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

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

Synology DS925+ NAS Leaked (AGAIN)

Par : Rob Andrews
14 avril 2025 à 16:00

The Synology DS925+ NAS is (STILL) Coming..and Soon

UPDATE 3rd May 2025:

The Synology DS925+ NAS is Now Released, and I have made a YouTube Video Review here, and a written DS925+ NAS here

ORIGINAL ARTICLE BELOW:

It is fast becoming the worst-kept secret in the world of network-attached storage, but Synology’s continued plans to launch refreshes of a number of their popular desktop devices received another public outing this weekend, when keen users on Reddit spotted the official pages for the Synology DS925+ and DX525 on Amazon.co.uk, listing hardware specifications, pricing, release dates, and general background info. Although the appearance of the DS925+ isn’t exactly surprising—given the large info drop semi-officially revealed at an official event by a user on Chiphell—it is nonetheless surprising to see these two official Synology products seemingly added by Synology themselves for Amazon distribution, yet with absolutely zero mention on the traditional Synology platforms (Synology Products, Synology Downloads, Synology Download Registry, etc). Nonetheless, this appearance has confirmed numerous details about the DS925+ hardware specifications, for good and for bad, so I wanted to go through the further confirmed specifications and what they mean.

Synology DS925+ NAS Confirmed Hardware Specifications

As previously alluded to last month in the previous leak, the Synology DS925+ will arrive with the already integrated CPU from AMD that featured on previous SMB releases—the V1500B. This is a quad-core CPU that allows for more cores, more threads (i.e. more vCPUs) than the R1600 in the DS923+, as well as a lower TDP—though also a lower total clock speed available at first. It arrives with 4GB of ECC memory that can be scaled up to 32GB via two SODIMM DDR4 slots. DS925+ includes 2 × 2.5GbE, a very welcome if somewhat overdue upgrade on this product series from Synology. The SSD compatibility for storage pools and the speed allocated to each slot is still TBC. The expansion capabilities of the DS925+ have changed from the long-running eSATA support and DX517 of older Synology devices and now lean towards popular USB-C, and this is what triggered the new DX525 expansion box. We are still awaiting confirmation of the confirmed speed of this USB-C port, as well as its broader compatibility for other things (given the larger variety of USB-C options available in the market compared with eSATA), but slides shown at the Synology partner event last month seemingly indicated that this will NOT be USB 3.2 Gen 2 10Gbps.

Probably the biggest and most controversial change here in the newer generation box is the removal of the mini PCIe upgrade slot that featured on the DS923+. The new DS925+ completely lacks this ability to scale up to 10GbE later down the line, which is probably going to upset a lot of users. PCIe modules they have sold (which would greatly explain, perhaps, the motivation for removing this feature), it is still something of a blow that this new generation device has removed a particularly appealing network upgrade path option. The motivation for this could be theoretically for multiple reasons, such as:

  • Synology might well have deemed the two-times 2.5GbE network connectivity on the DS925+ sufficient for the four drives of SATA storage that it features, as well as ensuring that the system does not overlap other devices higher in the product portfolio food chain too much.
  • The PCIe line distribution of this CPU and the chipset used on this board might result in limitations to the distribution of those lanes and therefore made the upgrade difficult to implement.
  • The USB-C port for expansions may support a 10GbE upgrade module down the line that Synology intend on rolling out—a bit of a long shot though, as currently USB-C to 10GbE is only afforded to TB3/TB4/USB4 connectivity and would commit a great deal of internal lane distribution to that port to accommodate this potential upgrade.
  • As previously alluded to, perhaps user integration of this upgrade slot on previous DS923+ devices was too low to justify accommodating this feature in the newest iteration.

Any of those reasons, or others, might well be why Synology decided to rescind this feature on this device. Nevertheless, it is something of a bitter pill that this device will not be featuring the ability to scale up out of the potential 5GbE bonded network connection that it arrives with and likely serves as a slight bottleneck to more high-performance hard drives in the SATA bays, as well as a significant cap on using SATA SSDs or M.2 NVMes in storage pools via the provided slots.

The AMD Ryzen R1600 and V1500B are both embedded CPUs used across Synology’s NAS lineup, but they serve distinct roles depending on the target user and workload. The R1600 is a dual-core, four-thread processor with higher clock speeds (2.6GHz base / 3.1GHz boost), making it ideal for environments that prioritize single-threaded performance—such as general file sharing, light server tasks, and basic backup operations. It has a TDP of 25W and is commonly found in more entry-level to mid-range Synology NAS models like the DS723+ and DS923+. By contrast, the V1500B is a quad-core, eight-thread CPU running at a lower base clock of 2.2GHz, but it delivers greater efficiency and significantly better multi-threading performance—essential for virtual machines, Docker containers, multiple user sessions, and parallel workflows. Its lower TDP of 16W also makes it a more efficient option for always-on deployments in business settings.

CPU Comparison: AMD Ryzen Embedded V1500B vs R1600

Specification AMD Ryzen Embedded V1500B AMD Ryzen Embedded R1600
Cores / Threads 4 Cores / 8 Threads 2 Cores / 4 Threads
Hyperthreading Yes Yes

Turbo Frequency (All Cores) Not Specified Not Specified
Overclocking No No
TDP 16W 25W
Cache (L1 / L2 / L3) 384KB / 2MB / 32MB 192KB / 1MB / 4MB
Socket Type BGA1140 BGA1140
Architecture Zen (Normal) Zen (Normal)
CPU Class Embedded / Mobile Embedded / Mobile
First Seen Q2 2021 Q4 2022
Single Thread Rating (CPUBenchmark) 1230 (-28.7% vs R1600) 1724 (Higher)
CPU Mark (Overall) (CPUBenchmark) 4829 (Higher) 3276 (-32.1% vs V1500B)
Estimated Yearly Power Cost $2.92 $4.56

What makes the V1500B particularly notable in the DS925+ is that this CPU was previously reserved for Synology’s larger SMB and enterprise-tier systems, such as the DS1621+, DS1821+, and DS2422+. By introducing it into a prosumer-class 4-bay NAS, Synology is clearly continuing its long-standing trend of moving mature hardware platforms down into lower product tiers over time, as the cost of components becomes more accessible and manufacturing scales improve. This strategy enables Synology to offer higher-tier performance at mid-tier price points, effectively refreshing their product range while maintaining price consistency. For users who prioritize multi-tasking, virtualized workloads, or long-term scalability, the arrival of the V1500B in the DS925+ marks a significant shift in capability for this tier of NAS.

Want to Understand How Synology NAS Product Refreshes Work, as well as Why Synology Chooses Certain Hardware? Read my article below:

Synology DS925+ NAS HDD and SSD Compatibility?

Unfortunately, there is no mention of Synology’s position on third-party hard drive and SSD compatibility on the new DS925+ confirmed yet. Realistically, basing it on the predecessor and other Synology Plus Series devices, at the very least, we’re going to see a repeat of the priority towards Synology’s own series of hard drives and SSDs, with a handful of third-party drives from Seagate, Western Digital, and Toshiba added to the support list. This has now become the status quo with the majority of Synology Plus Series and above devices, and if this device rolls out with that, I’m not going to say that it’s perfect, but at the very least it does still leave a narrow window open for users to use third-party hard drives without the system spitting alerts or amber warnings at you during setup.

As the system is being listed on the Amazon pages without drives included, that at the very least removes the concern of many that Synology may have been proceeding down the pre-populated system route, or being more rigid on the lock-in of the drives you can use on the system. Nevertheless, there is still the matter of the M.2 NVMe slots and whether this system will continue with the policy of third-party drives only being supported for use as caching, whereas Synology’s own M.2 NVMe drives support both caching and storage pools. It will most certainly continue with this position.

Synology DS925+ NAS Price and Release Date?

As originally predicted last month, the pricing of the DS925+ will be largely the same as that of the DS923+, as Synology is always keen to maintain the pricing at each tier of its portfolio year on year—even if sometimes that can result in the hardware being a little more lean despite the cost of components going up. I kind of respect how long Synology has been able to maintain the same price for their prosumer 4-bay device, right? All the way back since 2015, it has always arrived at that similar £550 price. Keep in mind that the price listed on the early leaked Amazon.co.uk page includes VAT, whereas pricing listed in other countries like the U.S. will likely not include tax.

With regards to the intended release date and availability of the DS925+, the Amazon leak page appears to indicate the 7th of May. Now, whether this has always been the plan by the brand when refreshing all of its currently existing product line, or it is a launch date that has been changed rapidly in light of discussions surrounding tariffs and stock travelling around the world, is yet to be confirmed. Nevertheless, that seems like a fairly reasonable launch date in light of the information—originally appearing online with the product page added to Amazon on April 8th—and the slow but steady gear Synology goes through when making a product live across traditional online retailers. You can use the links below to monitor the availability and price of the Synology DS925+ on Amazon, as it will redirect to your own region via the link.

Synology DS923+ vs DS925+ NAS – Buy Now or Wait?

When comparing the Synology DS923+ and DS925+, the differences are subtle but important depending on your priorities. Both NAS units share the same price point, run Synology’s DSM software with identical features, and include the same baseline 4GB DDR4 ECC memory (expandable up to 32GB). They also both lack integrated graphics, feature four SATA drive bays, and offer two M.2 NVMe Gen 3 slots for SSD caching. However, the DS925+ gains an edge in raw parallel processing power, featuring a quad-core, eight-thread AMD V1500B CPU, which translates to more virtual CPUs (vCPUs) for virtual machines and containerized applications. It also benefits from dual 2.5GbE ports, enabling up to 5GbE performance with Link Aggregation or SMB Multichannel, compared to the 2x 1GbE ports on the DS923+, which top out at 2GbE combined. Additionally, the DS925+ offers a faster expansion interface via USB-C (6Gbps) versus the older eSATA (5Gbps) on the DS923+.

Estimated Price ~£550 ~£550
Warranty 3 Years (5 Years with Extended Warranty) 3 Years (5 Years with Extended Warranty)

That said, the DS923+ still holds certain advantages. Its AMD R1600 CPU features a higher clock speed, which may offer better single-threaded performance in lighter tasks or low-concurrency applications. Crucially, the DS923+ supports an optional 10GbE upgrade via its mini PCIe slot, a feature completely removed in the DS925+, which could be a deal-breaker for users planning to grow into a higher-speed networking environment. So, should users buy the DS923+ now or wait for the DS925+? If 10GbE upgradeability or faster per-core performance is important for your workload, the DS923+ is still a strong option. However, if you’re prioritizing multi-threaded performance, better default network speeds, and a more modern expansion standard, the DS925+ is the more forward-looking choice—particularly for virtualization and container-heavy environments. Ultimately, both devices serve the same class of user, but choosing the right one depends on whether your focus is scalability or efficiency out of the box.

Buy a NAS Now or Not? – LET’S TALK TARIFFS BABY (sigh)

Par : Rob Andrews
9 avril 2025 à 17:27

The U.S. Tariffs and Their Looming Impact on NAS and Storage Tech

The United States has recently announced a sweeping set of import tariffs on goods from nearly every major trading partner in the world. This policy shift, driven largely by the country’s growing trade deficits with nations like China, the European Union, Vietnam, and others, imposes additional fees ranging from 15% to 50% on products entering the U.S. The implications go far beyond international politics—they’re about to hit consumers directly, especially in the realm of network-attached storage (NAS), data drives, and related IT infrastructure. For businesses and tech enthusiasts alike, this could drastically reshape buying decisions and the way storage technology is sourced and maintained in the years ahead.

Most NAS brands, regardless of their international reputation or market share, are headquartered—and more importantly, manufactured—outside the United States. While brands like Synology, QNAP, TerraMaster, and Asustor dominate the global NAS market, they are based in Taiwan and China—countries now subject to tariffs as high as 46%. Even U.S.-founded companies aren’t immune; Seagate and Western Digital, for instance, produce the bulk of their drives in Thailand, Malaysia, and other tariff-affected countries. Likewise, 45Drives, a Canadian company with a strong presence in the U.S. market, assembles its products in Nova Scotia. This global web of production means almost no storage brand will emerge from this tariff structure unscathed.

However, it’s not just the tariffs themselves that are concerning—it’s the uncertainty they create in the supply chain. Distributors, wholesalers, and resellers operate on tight margins and forecasting models. With the risk of sudden pricing hikes or shifts in demand, many are likely to reduce inventory levels rather than gamble on unstable costs. If distributors begin ordering fewer units or delaying shipments while waiting for clarity, that can result in long-term effects on availability down the chain. For consumers and IT professionals, this may translate into fewer options, slower shipping times, and inconsistent stock at retailers, especially for higher-end or business-class hardware.

This reduction in stock won’t be immediately obvious but will likely manifest in 3 to 6 months as upstream inventory runs out. Unlike the global chip shortages of previous years—which were driven by raw material scarcity and manufacturing delays—this looming shortage will stem from financial caution and policy volatility. Retailers might maintain listings but hold little-to-no actual stock, while lead times on specialized or enterprise-grade NAS solutions could stretch uncomfortably long. Resellers will be hesitant to overstock and risk capital loss, creating an environment where supply is bottlenecked before it even hits the storefront.

Another critical layer is the manufacturing cost ripple effect. Even products partially or fully assembled in the U.S. will see increased base costs if their components—be it PCBs, chips, enclosures, or storage platters—originate from affected countries. These costs are added long before the end product even appears on a website or in a store. What this means is that even before the tariff surcharge is applied to the final product, the wholesale cost has already been inflated. Once one manufacturer adjusts their pricing to reflect these new realities, competitors are likely to follow. The result will be a new pricing baseline that is unlikely to ever return to previous levels, even if some tariffs are eventually eased.

Some may hold out hope that this will prompt a new era of domestic manufacturing, particularly for brands looking to sidestep tariffs altogether. While this is a possibility, it’s far from an immediate solution. Setting up manufacturing in the U.S. involves immense logistical, financial, and regulatory challenges. Even if companies begin the process today, meaningful change is at least two to three years away. And critically, even if production is moved stateside, prices are unlikely to fall—once the market accepts a higher cost structure, manufacturers rarely roll back pricing, especially if demand remains strong. Historically, many brands have relied on international redistribution centers to navigate or lessen the impact of tax and tariff regimes. Countries like Singapore, Thailand, and the Netherlands have served as strategic re-export hubs, helping companies reduce costs and navigate trade restrictions. These setups have allowed goods to flow more freely into Western markets with minimal added expense. However, the comprehensiveness of the new U.S. tariff list is expected to close many of these loopholes. As more countries are swept into the tariff net, fewer workarounds remain viable, which means both gray market and authorized resellers will struggle to avoid passing costs along to the buyer.

This brings us to the practical question: should consumers and businesses buy their NAS systems now or wait? While there’s no one-size-fits-all answer, those who anticipate needing storage solutions in the next three to six months may be better off acting sooner. The intersection of declining stock availability, rising manufacturing costs, and pending tariff implementation could create a narrow window where current prices and availability are the best we’ll see for a while. Delaying too long risks not only paying more but facing potential wait times for critical systems. That said, users with stable systems and strong backup routines may prefer to ride out the uncertainty, at least temporarily. Ultimately, the storage industry—like much of the tech sector—is facing a period of turbulence. Boardrooms across the globe are likely holding emergency meetings to re-evaluate supply chains, regional assembly strategies, and consumer pricing models. But without clear long-term policy direction, many companies will be hesitant to make bold changes, opting instead for a wait-and-see approach. For now, the best advice is to monitor inventory levels closely, stay informed about regional pricing trends, and—if you’re in the U.S.—think seriously about whether a short-term investment in your storage infrastructure might save you money and headaches down the line.
