Get Graphics Drivers and Hardware Transcoding BACK for Plex/Jellyfin/Emby on your Synology NAS

Note – the video on this fix will be published soon and I will update this article with images ASAP.

Synology’s 2025 refresh brought the DS225+ and DS425+ with the familiar Intel Celeron J4125, but it also quietly removed the kernel graphics driver support that Plex, Jellyfin, and Emby use for hardware transcoding of H.264 and HEVC. This guide explains what changed, why it matters for real-world streaming, and how you can restore GPU-accelerated transcoding on these models using an unofficial SSH method shared by the community. If you rely on your NAS to reshape 4K or high bitrate files for phones, tablets, hotel TVs, or limited connections, this walkthrough will help you get that efficiency back.

What Happened to Hardware Transcoding on the Synology 2025 NAS, and Why Is This a Problem

When Synology launched the 2025 “x25” lineup, users expected a minor refresh of familiar models like the DS225+ and DS425+. Instead, they discovered that Synology had removed the i915 graphics driver from DSM, effectively disabling hardware transcoding on the Intel Celeron J4125 CPU. This meant that Plex, Jellyfin, and Emby could no longer tap into the iGPU’s Quick Sync Video capabilities. Synology confirmed the change in support tickets, explaining that both H.264 (AVC) and H.265 (HEVC) transcoding had been deliberately blocked at the kernel driver level. The company cited licensing costs for HEVC, even though AVC is license-free, and argued that most client devices already support native playback. The earliest and longest discucssions on this topic are HERE on this Plex Forum thread.

The result is a significant downgrade for users who bought these models expecting the same multimedia performance as their predecessors. Instead of 10–20% CPU usage during hardware-accelerated transcoding, users now see 80–100% CPU utilization when reshaping video on the fly. For remote streaming, converting 4K to 1080p or 720p becomes slow, inefficient, and often unworkable. This change undermines the value proposition of the J4125 platform and leaves Plex and Jellyfin users with hardware that is technically capable but artificially restricted, creating frustration across the Synology community.

Disclaimer: This Is Unofficial – Know the Risks!

Before diving into the workaround, it is important to understand that this method is not supported by Synology and involves altering core system modules via SSH. These steps rely on community-compiled drivers and are provided “as is,” without warranty. Making changes at the kernel level can cause instability, break after DSM updates, or in the worst case, lead to data loss if mistakes are made. You should always keep verified backups of your data before proceeding, and only attempt this if you are comfortable working with the command line and root-level access. Proceed entirely at your own risk.

Step By Step Guide to Get J41225  Graphics Drivers Hardware Transcoding Back

1. Download the Source Code

   • Go to Dave Russell’s GitHub repo (007revad) and download the Source Code (.zip) for the graphics driver fix.

   • 

   • Do not unpack the archive on your computer.

2. Create a Folder on Your NAS

   • Log into DSM and create a new Shared Folder (e.g. scripts) on your main volume.

   • 

   • Make sure your DSM account has full access, since root privileges will be needed later.

3. Upload the Archive

   • Use File Station or SMB to upload the .zip file into the new scripts shared folder.

   • 

   • Once uploaded, extract it on the NAS by right-clicking and selecting Extract Here.

   • 

   • If extraction creates subfolders, move the relevant script files (such as transcode_4_x25.sh) directly into the main scripts directory for easier referencing.

   • 

4. Create a Scheduled Task

   • Open Control Panel > Task Scheduler.

   • 

   • Select Create > Triggered Task > User-defined Script.

   • 

   • Give the task a name (e.g. Synogfx).

   • 

   • Set the User to root.

   • Set the event to Boot-up so the script runs every time the NAS restarts.

   

5. Point to the Script

   • In the task settings, paste the full path to the script file, for example:

     sh /volume1/scripts/transcode_4_x25.sh


   • If unsure, right-click the .sh file in File Station, select Properties, and copy the full directory path.

   • 

6. Confirm and Save

   • DSM will warn you about using root and non-standard scripts. Acknowledge this and proceed.

   • 

   • Enter your DSM admin password when prompted.

   • The scheduled task will now appear in the list.

   • 

7. Run the Script

   • Right-click the new task and select Run to execute it immediately.

   • 

   • Optionally, reboot your NAS to confirm that the driver loads automatically on startup.

   • 

8. Verify Hardware Transcoding

   • Open Plex (or Jellyfin/Emby) and play a file requiring transcoding.

   • 

   • Check playback statistics: you should now see HW (hardware transcoding) instead of CPU-only usage.

Conclusion

Synology’s decision to remove iGPU drivers from the 2025 DS225+ and DS425+ left many users frustrated, especially those who rely on Plex or Jellyfin for remote streaming. While the company cites licensing costs and client-side decoding as justification, the hardware itself remains fully capable of transcoding. Thanks to community-driven efforts, it is possible to re-enable Quick Sync on these models with an SSH-based workaround. This fix restores the efficiency and functionality users expected, though it comes with risks and requires maintenance after reboots. For multimedia enthusiasts who value hardware transcoding, this unofficial solution may be the only way to unlock the true potential of these NAS systems.

Why are NAS Systems not 10GbE as Standard Right Now?

It is 2025, yet the majority of NAS systems on the market continue to ship with 1GbE or, at best, 2.5GbE networking, leaving many users questioning why 10GbE has not become a standard feature. Over the past decade, the cost of 10GbE networking equipment, including switches, NICs, and adapters, has steadily declined, and the technology has long since moved from being an enterprise-only option into mainstream availability. Home labs, creative professionals, and small businesses are increasingly working with 4K and 8K media, large VM environments, and multi-terabyte datasets, all of which can easily saturate a 1GbE or even 2.5GbE connection. Despite this shift, when browsing the portfolios of Synology, QNAP, Asustor, TerraMaster, or even newer DIY-friendly NAS brands, the entry-level and mid-tier systems remain locked at bandwidth speeds that are already dwarfed by modern SSD arrays and multi-bay RAID configurations.

asdasd

This gap between user expectations and manufacturer offerings has become more striking as affordable consumer motherboards and even some mini-PCs now integrate 5GbE or 10GbE as standard. By contrast, NAS vendors still tend to position 10GbE as a high-end add-on or restrict it to flagship models, often requiring costly proprietary NIC upgrades. For the average buyer, this creates the perception that NAS devices are lagging behind broader networking trends and are artificially constrained to maintain price tiers. The reality is more complex. The question of why 10GbE has not become universal in NAS hardware cannot be answered solely by pointing to falling market prices of controllers and switches. Instead, the explanation lies in a mix of economics, hardware design limitations, CPU lane allocations, and the fact that networking itself is evolving beyond 10GbE into alternatives like 25GbE and USB4. All of these factors together show why the integration of 10GbE into NAS devices remains more complicated than it may first appear.

Discussing the Issue / Barriers to Manufacturers

One of the most persistent barriers to universal 10GbE adoption in NAS systems is the economic reality of how these devices are positioned. Vendors like Synology, QNAP, and Asustor operate in a layered product ecosystem, where each tier is designed to push customers toward more expensive models. Entry-level devices often compete on affordability rather than raw performance, meaning that features like 10GbE are deliberately held back to differentiate mid-range and enterprise systems. The actual bill of materials (BOM) cost for including 10GbE hardware is lower than it was five years ago, but manufacturers still view it as a premium feature that justifies higher price points. By holding 10GbE in reserve for upper tiers, vendors protect their margins, avoid cannibalising sales of more profitable models, and keep upgrade paths clear for customers as their needs grow. This is not simply technical gatekeeping but a conscious market segmentation strategy.

A second, more technical challenge comes from CPU and chipset design. The processors used in affordable NAS devices are almost always low-power embedded models—Intel Celeron, Atom, or entry-level AMD Ryzen Embedded chips—which provide only a limited number of PCIe lanes. These lanes must be distributed across storage controllers, NVMe slots, expansion slots, and network interfaces. Introducing 10GbE requires not only dedicating at least two, and often four, PCIe lanes, but also ensuring that the CPU can handle the higher throughput without becoming the bottleneck. If a vendor reallocates lanes to add 10GbE, they may have to reduce the number of NVMe slots, cut down on SATA ports, or compromise expansion card bandwidth. For many manufacturers, it is simpler to leave 10GbE out of the base design than to risk producing a system that looks good on paper but struggles to deliver in practice.

Beyond lane allocation, there is also the issue of power, thermals, and board layout. 10GbE controllers typically draw more power and generate more heat than 1GbE or 2.5GbE chips. In compact NAS enclosures designed for low-noise operation, this can force more aggressive cooling solutions or tighter thermal management. For brands already working within strict acoustic and energy efficiency limits, especially in home or small office NAS devices, the integration of 10GbE becomes a balancing act between speed and stability. Higher thermal load can also reduce the overall lifespan of components or require larger enclosures, both of which erode the appeal of entry-level systems where buyers expect compact and efficient designs.

Another factor that discourages widespread 10GbE adoption is ecosystem alignment. NAS vendors are keenly aware that a large percentage of their target audience does not yet operate in 10GbE-ready environments. Even though 10GbE switches and NICs are more affordable in 2025, many households and small offices still rely on routers and switches with 1GbE or 2.5GbE uplinks. For these users, the inclusion of 10GbE would have little practical benefit, since the rest of the network infrastructure cannot support it. From the manufacturer’s perspective, bundling 10GbE into a device that will simply be throttled by the customer’s network backbone risks making the feature look pointless, or worse, “non-functional.” As such, 10GbE tends to be reserved for prosumer and enterprise segments, where it is more likely that users already have or are willing to invest in compatible infrastructure.

Finally, there is a subtle but important business factor at play: vendor ecosystems and upsell opportunities. Many NAS brands sell proprietary 10GbE upgrade cards or branded NICs, which can only be used with their systems. By omitting onboard 10GbE but providing expansion slots, vendors create an additional revenue stream while giving customers flexibility to upgrade later. This model also ensures that users who truly require 10GbE end up spending more within the brand’s ecosystem, while casual buyers stick to lower-cost systems that do not overdeliver. In this sense, the absence of 10GbE on affordable NAS units is not only about technical limitations, but also about preserving a staged upgrade model that aligns with each brand’s long-term revenue strategy.

The Solution – How Can 10GbE Be More Accessible?

The landscape for 10GbE networking hardware has improved significantly in the last few years, with controllers becoming cheaper, more efficient, and easier to integrate into consumer systems. Early 10GbE relied heavily on costly Intel or Mellanox chipsets designed primarily for enterprise servers, often priced in the hundreds of dollars per card. Today, vendors such as Realtek, Aquantia (now under Marvell), and Broadcom produce consumer-focused 10GbE controllers that are smaller, run cooler, and consume less power. These newer chipsets are also designed to integrate more smoothly with mainstream CPUs and motherboards, reducing the need for complex PCB layouts. The result has been a marked reduction in the cost of standalone NICs and USB-to-10GbE adapters, which now frequently sell for under $100, making them accessible even for home users experimenting with faster networking.

Even with this progress, manufacturers remain hesitant to make 10GbE a baseline feature across all NAS devices. Part of the reason lies in how modern NAS systems must juggle limited resources. As CPUs have shifted to PCIe Gen 4 and Gen 5, the available bandwidth has increased, but vendors are also using these lanes to expand NVMe storage pools, enable GPU acceleration, or add AI-focused co-processors for surveillance, indexing, or media analysis. In many cases, vendors see greater value in offering more M.2 slots, dual PCIe expansion options, or flexible NIC bays than in permanently dedicating space to 10GbE. This explains why hybrid designs are now common: devices shipping with 2.5GbE or 5GbE onboard, with a dedicated slot for an optional 10GbE card. Such configurations give users a faster-than-gigabit baseline, but also keep upgrade paths open for power users who truly need multi-gigabit networking.

The state of 10GbE is also being influenced by the rapid adoption of adjacent technologies. 2.5GbE has become the de facto standard in new consumer motherboards and mid-tier switches, offering a cheap and widely compatible upgrade path for everyday users who want more than 1GbE without changing their cabling. At the other end of the spectrum, higher-speed networking such as 25GbE or 40GbE is filtering down from data centres to advanced prosumer setups, while direct-connect solutions like Thunderbolt 4 and USB4 offer bandwidth well beyond 10GbE with less CPU overhead and simpler plug-and-play deployment. Software optimisation is also playing a role: modern NAS operating systems increasingly support IP over Thunderbolt or USB4, which provides a parallel path to multi-gigabit performance without the traditional reliance on Ethernet standards. As a result, 10GbE finds itself squeezed in the middle—too expensive to be a no-brainer at the entry level, but increasingly overshadowed by faster alternatives at the top end. It remains a critical sweet spot for small businesses and creative professionals, but its window of dominance is being challenged by the pace of networking innovation.

Verdict and Conclusion – Buy a 10GbE NAS Now or Wait?

The question of why 10GbE has not become a standard feature across NAS devices in 2025 does not have a single answer, but rather a convergence of factors. Manufacturers face technical challenges in CPU lane allocation, thermal management, and system design, while also making deliberate market choices to protect product segmentation and encourage upsell opportunities. At the same time, 10GbE sits in an awkward position within the networking landscape: cheaper and more efficient than ever, yet increasingly bypassed by the widespread adoption of 2.5GbE on the low end and the emergence of 25GbE, Thunderbolt, and USB4 on the high end. For now, this means that 10GbE remains reserved for higher-tier NAS systems where the hardware can genuinely sustain its throughput and where the user base is prepared to invest in compatible infrastructure. While prices will continue to fall and adoption will grow, it is unlikely that every NAS will adopt 10GbE as standard before other technologies begin to replace it as the next performance baseline.

5 affordable Turnkey 10GbE NAS Solutions (Between $499 and $699)

For years, 10GbE networking has been seen as a premium feature reserved for high-end or enterprise-grade NAS devices, often pushing total system costs well beyond the reach of home users and small businesses. However, as controller prices have dropped and demand for faster data transfers has grown, a new wave of affordable NAS solutions has started to appear with built-in 10GbE. These systems no longer require expensive proprietary upgrade cards or third-party NICs, and many sit comfortably below the $699 / £599 price point. They cover a range of use cases, from compact SSD-based NAS devices to rackmount storage appliances and versatile desktop units. Below is a selection of some of the most notable options currently available, each offering a balance of performance, connectivity, and affordability for users who want to move beyond 1GbE or 2.5GbE without breaking the bank.

UniFi UNAS Pro (7-Bay, Rackmount)

I keep coming back to two words for the UniFi UNAS Pro—fundamentals and consistency. UniFi has clearly focused on making this system a strong addition to their ecosystem, prioritizing the essential storage needs of a NAS. They’ve succeeded in this, but comparisons with long-established competitors are inevitable. While solid, reliable, and stable, the UniFi UNAS Pro will take time to be competitive on the software front. If you’re deeply invested in the UniFi ecosystem, you’ll appreciate its ease of use and integration. However, outside of a UniFi network, it may feel feature-light compared to alternatives. The pricing is competitive for a launch product at $499, and while it’s not the best NAS on the market, it’s the most user-friendly and UniFi-ready. It will likely satisfy many users’ needs. I can certainly see this being integrated into existing UniFi networks as a 2nd stage backup alongside their already existing 3rd party NAS solution, with the potential to graduating to their primary storage as Ubiquiti continue to evolve this platform above and beyond the fundamentals their have nailed down in the UNAS Pro system.

• Approx. Price: $499 / £400

• Specs: ARM Cortex-A57 quad-core CPU, 8 GB RAM, seven 2.5″/3.5″ SATA bays, 1×10GbE SFP+ and 1×1GbE.

• Why It Stands Out: Exceptional price-to-performance for pure storage needs. Lacks advanced multimedia or container apps but ideal for high-speed backups in a rackmount setup.

UGREEN NASync DXP4800 Plus

BOTTOM LINE – The UGREEN NASYnc DXP4800 Plus does not feel ‘finished’ yet and still needs more time in the over, but UGREEN have been very clear with me that this product is not intended for release and fulfilment till summer 2024 and improvements, optimization and product completion is still in progress. Judging the UGREEN NAS systems, when what we have is a pre-release and pre-crowdfunding sample, was always going to be tough. The DXP4800 PLUS is a very well put-together NAS solution, arriving with a fantastic launching price point (arguably even at its RRP for the hardware on offer). UGREEN has clearly made efforts here to carve out their own style, adding their own aesthetic to the traditional 4-bay server box design that plagues NAS boxes at this scale. Equally, although they are not the first brand to consider Kickstarter/Crowdfunding for launching a new product in the NAS/personal-cloud sector, this is easily one of the most confident entries I have seen yet. The fact that this system arrives on the market primarily as a crowdfunded solution (though almost certainly, if successful, will roll out at traditional retail) is definitely going to give users some pause for thought. Equally, the UGREEN NAS software, still in beta at the time of writing, although very responsive and nailing down the basics, still feels like it needs more work to compete with the bigger boys at Synology and QNAP. Hardware architecture, scalability, and performance are all pretty impressive, though the performance of the Gen 4×4 M.2 NVMe slots didn’t seem to hit the numbers I was expecting. Perhaps a question of PCIe bottlenecking internally, or a need for further tweaking and optimization as the system continues development. Bottom line, with expected software updates to roll out closer to launch and fulfillment, such as an expanded App center and mobile client, the UGREEN DXP4800 Plus is definitely a device worth keeping an eye on in the growing Turnkey and semi-DIY NAS market. As an alternative to public cloud services, this is a no-brainer and worth the entry price point. As an alternative to established Turnkey NAS Solutions, we will hold off judgment till it is publicly released.

• Approx. Price: $595 / £475

• Specs: Intel Pentium Gold 8505 (6-thread), 8 GB DDR5, 4×SATA + 2×M.2 slots, 1×10GbE and 1×2.5GbE, plus HDMI, USB-C, USB-A, and SD reader.

• Why It’s Attractive: Well-rounded design with rich connectivity and media support, undercuts most rivals on price and features.

The landscape of 10 Gigabit Ethernet networking has a significant shift over the past few years, with hardware that was once considered enterprise-only gradually trickling down to the consumer and prosumer market. Affordable multi-gig switches, particularly those with 2.5G or SFP-only configurations, are now commonplace. However, the search becomes much more complicated when you’re looking for a compact, budget-friendly 10GbE switch that combines both RJ45 copper and SFP+ fiber ports — and adds basic managed features to the mix. This is precisely where the Goodtop 6-Port 10GbE Managed Switch positions itself, offering four 10GBase-T ports, two SFP+ ports, and a claimed 120Gbps backplane bandwidth, all for around $140 on AliExpress.

At this price point, it’s important to approach products like this with realistic expectations. The Goodtop switch is not aiming to compete with the likes of Cisco, Aruba, or even MikroTik in terms of long-term support or security posture. Like many white-label or lesser-known brands shipping out of China, concerns around firmware transparency, update frequency, and potential vulnerabilities are valid. This is particularly relevant for users planning to expose management interfaces to external networks or integrate these switches into larger, more sensitive environments. Still, for isolated use in lab setups, home networks, or behind firewall-protected infrastructure, devices like this can offer compelling value — if they deliver on core functionality. This review takes a closer look at the Goodtop switch’s physical design, port configuration, internal hardware, software interface, and performance characteristics. Rather than focusing on theoretical specs alone, this analysis is based on hands-on testing to determine where the unit succeeds, where it cuts corners, and what kind of buyer it’s realistically suited for.

Goodtop Budget 6 Port 10GbE Switch Review – Quick Conclusion

The Goodtop 6-Port 10GbE Managed Switch delivers impressive value by combining four 10GBase-T and two 10G SFP+ ports in a compact, low-cost form factor, making it one of the most affordable mixed-media 10GbE switches on the market. It performs reliably under load, supports a full set of essential Layer 2 features like VLANs, link aggregation, and QoS, and provides a practical way for home lab users or small setups to adopt 10G networking without overspending. However, the switch’s low price is reflected in its build quality, fixed-speed noisy fan, and a barebones, unintuitive web interface that may challenge less experienced users. Security features are minimal, with no HTTPS, 2FA, or multi-user support, making it best suited for isolated, firewall-protected environments rather than critical infrastructure. For technically confident users seeking affordable, high-speed connectivity in a controlled setting, the Goodtop switch is a capable and cost-effective option—as long as its limitations are clearly understood.

Goodtop Budget 6 Port 10GbE Switch Review – Design

The Goodtop 6-Port 10GbE switch adopts a compact footprint and minimalist industrial design that aligns with many of the budget-friendly networking products emerging from OEMs in the Chinese market. Its chassis measures 200mm x 118mm x 44mm and is constructed from a thin, painted sheet metal. At just under 700 grams, the device is easy to handle and unobtrusive on a desk or shelf. It supports both desktop placement and wall mounting, the latter made possible by a pair of hook points integrated into the casing. While the construction is adequate for light to moderate use, it doesn’t offer the heft or rigidity seen in more enterprise-leaning gear.

There are no rubber feet to reduce surface vibration, nor any rack-mounting ears included by default. The paint finish is clean but basic, and minor flexing of the panels is possible under moderate pressure. These design choices reflect an emphasis on affordability rather than robustness, and users intending to deploy this switch in harsher physical environments may want to consider added enclosure or structural reinforcement. Still, for indoor use where vibration and temperature control are consistent, the physical form is entirely serviceable.

Thermal management is handled by a single small-diameter fan mounted laterally inside the chassis, supported by perforated ventilation cutouts on the opposing side. This active cooling setup is necessary given the heat output of the internal 10GbE components, particularly when all ports are under load.

During testing, the fan proved effective in maintaining safe thermal levels across typical workloads, with internal temperature readings ranging between 31°C and 36°C depending on ambient conditions and port usage. However, the fan’s acoustic characteristics are worth noting: it operates at a fixed RPM, regardless of system temperature or network activity.

This results in a constant hum that registers between 38 and 41 dBA — not excessive, but certainly noticeable in quiet environments. There are no accessible fan speed controls in the management interface, and the unit lacks thermal sensors or thresholds that would allow for adaptive fan curves.

For users operating this switch in a studio, home office, or any acoustically sensitive environment, the persistent fan noise could be a drawback. Modifications, such as third-party silent fan replacements, may be feasible but would require disassembly and some DIY effort. Overall, the cooling solution works, but its implementation is clearly a compromise between function and cost.

Goodtop Budget 6 Port 10GbE Switch Review – Hardware & Connections

The Goodtop switch is equipped with a total of six 10-Gigabit-capable ports, split between four RJ45 (10GBase-T) and two SFP+ slots. This particular configuration is uncommon at this price tier, especially among switches that offer web-based management. The inclusion of both copper and fiber interfaces in one device provides flexibility for mixed network environments — ideal for users bridging legacy copper infrastructure with newer fiber deployments or integrating NAS devices and uplinks with varying interface standards. All six ports are located on the front panel, clearly labeled and spaced far enough apart to accommodate bulkier cables and transceivers without interference.

The RJ45 ports support standard multi-gig Ethernet protocols, with backward compatibility for 100Mb, 1G, 2.5G, and 5GBase-T connections, depending on cabling. According to the manufacturer’s specs, Cat6 or better is recommended for full 10GBase-T performance up to 100 meters.

The SFP+ ports accept a wide range of 10G transceivers, including DACs (Direct Attach Copper), SR/LR fiber modules, and media converters, offering strong compatibility with third-party optics and hardware.

Despite its low cost, the switch claims a 120Gbps backplane switching capacity and a non-blocking architecture capable of 89.28 million packets per second. While exact benchmarking under full simultaneous port saturation wasn’t possible due to hardware limitations during testing, four concurrent 10GBase-T connections were tested successfully with sustained bidirectional transfers.

Under load, the unit handled transmission reliably without packet loss or obvious performance degradation. Power consumption scales with usage: idle draw sits at approximately 7.5 watts with no connected clients, while active use with four 10G copper links under sustained read/write activity peaked around 19.8 watts.

These values are in line with expectations for a full-10G switch operating with active cooling, and while not low, they are acceptable for most desktop or lab environments. It’s worth noting that due to heat generation and airflow limitations, users may experience rising internal temperatures if all six ports are driven continuously, especially in poorly ventilated setups. However, the flexibility to use either media type and the stable throughput on tested ports suggest that the internal switching logic and port handling are effectively implemented, given the device’s pricing and market position.

Internally, the Goodtop 6-Port 10GbE switch is built around a Realtek chipset configuration comprising the RTL9303 switch controller and RTL8264B PHYs, a pairing commonly found in recent budget and white-label 10G networking products. These components are designed to deliver basic Layer 2 managed functionality with support for VLAN tagging, link aggregation, and other expected switching features. Two medium-sized aluminum heatsinks cover the main chips, with thermal paste applied to ensure contact and heat dissipation, albeit passively reliant on the unit’s single fan for airflow. There is no internal battery backup, surge suppression beyond nominal protection, or modular power regulation — design choices consistent with its low cost.

The unit includes a modest 12Mbit of packet buffer memory and supports a MAC address table size of up to 16K entries, which should be sufficient for most small-to-medium environments. There are no removable components or visible debugging headers, and the board layout is straightforward with no major thermal bottlenecks observed during operation. Overall, the hardware design is minimal but appropriate for the target use case: non-critical environments requiring inexpensive multi-gig connectivity without expectations of advanced redundancy or hardware resilience. While it doesn’t compete with enterprise-class internals in terms of engineering quality or extensibility, it does reflect a competent implementation of entry-level switching silicon with functional thermal management.

Goodtop Budget 6 Port 10GbE Switch Review – Software

The Goodtop switch ships with a built-in web-based management interface that allows users to configure a range of Layer 2 features typical of entry-level managed switches. The interface is accessible via a browser once an IP address is assigned, and no additional software is required. However, the overall presentation and usability of the software are quite basic. The UI lacks visual polish, contextual help, or guided configuration tools. Navigation is functional but unintuitive, with much of the terminology and layout appearing generic and unbranded — a likely result of the firmware being repurposed from a reference design or OEM platform.

There are no wizards or safety prompts to prevent misconfiguration, which could make the switch challenging for less experienced users to manage safely. Additionally, there is no mobile optimization or official companion app, and the interface does not support HTTPS out of the box. Firmware updates are possible via the web console, though update channels or changelogs are not provided, and documentation is sparse.

Despite its limited interface design, the switch includes a solid range of features that are normally found in more expensive units. These include core Layer 2 controls and essential traffic management capabilities, offering flexibility for VLAN segmentation, link aggregation, and network troubleshooting. While these features are mostly geared toward technical users, they cover a surprisingly broad spectrum of functionality for a switch in this price bracket. However, it’s worth noting that the interface offers no access controls beyond a single user account, no two-factor authentication, and no role-based access — all of which may concern users deploying this switch in sensitive or multi-user environments. Fan speed control, system logs, or SNMP monitoring are also absent, limiting the unit’s viability for more advanced administrative needs. Key supported features include:

• VLAN support (802.1Q, VLAN IDs 1–4094)

• Port-based VLAN assignment

• Link Aggregation (LACP)

• Loop detection

• Jumbo frame support (up to 9K bytes)

• MAC address filtering

• Port mirroring

• Broadcast storm control

• QoS / Port-based priority settings

• Traffic statistics monitoring

• Basic firmware upgrade support

These tools are adequate for static network environments or those with fixed segmentation needs, but administrators seeking dynamic configuration, remote logging, or integration with monitoring platforms will find the software lacking in depth.

Goodtop Budget 6 Port 10GbE Switch Review – Verdict and Conclusion

The Goodtop 6-Port 10GbE Managed Switch offers an appealing combination of features that are rarely found together in a product at this price point. With four 10GBase-T copper ports and two 10G SFP+ fiber slots, it caters to users who need to bridge different media types without investing in multiple specialized devices. The unit delivers consistent throughput, a practical management interface, and baseline Layer 2 capabilities suitable for most small-scale, static deployments. For those building or expanding home labs, adding high-speed links between servers and NAS devices, or testing 10GbE equipment without committing to enterprise-level budgets, this switch is a very practical and accessible option. The price tag — typically hovering between $130 and $140 — is particularly compelling when compared with similar switches from established brands, which often cost two to three times as much while offering fewer ports or omitting management functionality.

However, it’s important to understand what trade-offs make that low cost possible. Physically, the unit is built with budget-grade materials, and although the compact design is functional, the thin metal chassis lacks the rigidity and passive cooling features seen in more expensive models. The inclusion of active cooling is necessary given the switch’s full 10GbE capability, but the fixed-speed fan results in a persistent acoustic presence that may not be acceptable in quiet workspaces. In terms of power usage and thermal output, the switch performs within expectations, though it naturally draws more power than multi-gig or 1G devices — something to consider if operating in environments sensitive to power efficiency or heat buildup.

On the software side, the web-based management interface includes a reasonably full feature set for configuring VLANs, link aggregation, QoS, and port monitoring, but the UI is visually dated, lacking intuitive navigation, helpful prompts, or contextual explanations. For seasoned users comfortable with networking terminology and manual configuration, this isn’t a major obstacle. However, newcomers may find the software overwhelming or difficult to use without external guidance. Security is another area where the switch shows its limitations. The absence of HTTPS access, multi-user management, or basic features like two-factor authentication limits its suitability for exposed or multi-tenant environments. Firmware updates are possible, but no public update path or official support channels are offered, making long-term update viability uncertain.

Ultimately, this is a product built around value — and that value is real, as long as buyers know what they’re getting into. The Goodtop switch does not pretend to be a polished enterprise-grade solution, nor does it offer the ecosystem integration or long-term support found in more expensive alternatives. Instead, it provides raw functionality: six full-speed 10GbE ports, a working management layer, and compatibility with a wide range of copper and optical transceivers. For environments that are self-contained, technically managed, and not security-critical, this device offers performance that aligns well with its low cost. For those willing to make small compromises on build quality and user experience, it’s an excellent option for extending 10G connectivity without overspending.

 Synology DS425+ Review – Should You Buy This NAS?

The Synology DS425+ is a 4-bay NAS system launched in mid-2025 as part of the company’s continued refresh of its Plus Series product line, replacing the DS423+. It is designed to serve home power users, creative professionals, and small business environments that require a balance of reliable storage, streamlined software integration, and modest multimedia capabilities. The unit retains a familiar chassis and architecture, featuring the Intel Celeron J4125 quad-core processor (2.0 GHz base, 2.7 GHz burst) with integrated graphics support, 2GB of soldered DDR4 memory (expandable up to 6GB with an additional 4GB Synology module), and two M.2 NVMe slots intended primarily for SSD caching using Synology-verified drives.

DSM Software Ecosystem and Integration

One of the most compelling reasons to consider the DS425+ is its support for Synology’s DiskStation Manager (DSM), a mature and highly integrated NAS operating system. DSM 7.2, which comes preinstalled, offers a unified and consistent user experience with a wide range of built-in applications tailored for home users, remote workers, and small office setups. Core tools like Active Backup for Business allow centralized backup of entire operating systems, folders, and virtual machines, making the DS425+ useful as a bare-metal recovery or disaster recovery node. Hyper Backup enables encrypted, versioned backups to local, remote, or cloud destinations, while tools like Snapshot Replication provide rapid rollbacks and protection against ransomware.

Synology also offers sector-specific solutions through packages like Surveillance Station and Virtual Machine Manager, the former allowing support for up to 40 cameras (with up to 800FPS at 1080p H.264), and the latter providing basic VM hosting for Linux and lightweight Windows workloads. These tools are tightly optimized for the hardware, with low overhead and accessible browser-based management. Furthermore, the DS425+ supports Synology Hybrid RAID (SHR), giving users more flexibility when mixing drive capacities and minimizing unused storage space compared to traditional RAID models.

DSM extends beyond simple storage management by including companion apps like Synology Photos, Drive, and Chat, all of which are compatible with Windows, macOS, Android, and iOS. The DS425+ integrates these tools with centralized user management, group permissions, and support for LDAP and Active Directory.

For users who value reliability, Synology’s proactive security strategy—including its public security advisories, pen-testing initiatives, and in-house incident response—adds extra confidence to the long-term stability and safety of the system. In many cases, users report that the simplicity and polish of DSM is what keeps them loyal to the Synology platform, even when hardware specifications appear modest.

Strict Drive Compatibility and Locked Storage Expansion

One of the most significant limitations of the DS425+ is its strict enforcement of Synology-only drive compatibility, particularly for both 3.5″ HDDs and M.2 NVMe SSDs. As of mid-2025, this model only allows full functionality when paired with Synology-branded drives, such as the HAT5300 series for hard disks or SNV3410/3510 for SSDs.

If users attempt to install non-Synology drives—even widely used options like Seagate IronWolf or WD Red—the system will either block the drives entirely or present warnings and restrict key functionality, such as RAID rebuild, hot spare assignment, or expansion. This policy represents a significant departure from Synology’s historically broader compatibility stance and has become a source of ongoing controversy among users and reviewers alike.

From a practical standpoint, this limitation can result in higher upfront costs, reduced flexibility in sourcing drives, and long-term concerns about availability and vendor lock-in. For example, Synology’s high-capacity enterprise HDDs are often difficult to find in retail channels and may be priced at a premium compared to similar offerings from Seagate or Toshiba.

Users migrating from older Synology systems who want to reuse perfectly functional drives may find themselves unable to do so, as the new system won’t allow proper array recovery or expansion unless all drives meet the strict compatibility criteria. While this approach enables Synology to tightly optimize performance and reliability, it effectively turns the DS425+ into a semi-proprietary ecosystem where even core storage components are vendor-restricted.

This is particularly frustrating for experienced NAS users who expect to mix and match drives or who run environments where hardware recycling and drive lifecycle management are critical. The decision also impacts future-proofing: users who want to grow their arrays over time must now ensure drive stock alignment with Synology’s approved list, which may change over time or vary by region. Despite DSM’s strengths, this hard stance on compatibility significantly undermines one of the key selling points of NAS platforms—modularity—and could be a dealbreaker for value-conscious users or those with existing disk investments.

Low Noise and Power Efficiency for 24/7 Use

Another advantage of the DS425+ lies in its energy-efficient and acoustically quiet design, which makes it highly suitable for constant operation in homes, studios, or office environments where noise and heat are critical considerations. Based on extended testing, the system consumes just 28.25W under access load and drops to as low as 6.10W in HDD hibernation, making it one of the more economical NAS units in its class when measured over long-term 24/7 usage.

Even when populated with four 4TB hard drives and placed under sustained load, real-world power draw rarely exceeded 44W during high CPU utilization. This is further aided by the relatively low thermal output, with ambient casing temperatures measured around 32°C and drive bays stabilizing at just 35°C under load.

In terms of acoustic performance, the DS425+ is equipped with two 92mm fans, and noise testing shows the system remains quiet enough for close-proximity deployment. In idle mode with the fans on their lowest profile, it registers a sound level between 36 to 38 dB(A), which increases only moderately under load or at medium fan speed. Even when the system was manually set to full fan speed with high drive activity, noise output peaked at 53 dB(A)—still manageable for most non-silent workspaces. This operational profile makes the DS425+ appealing to users seeking a low-maintenance NAS that can be discreetly placed in a shared room, office, or AV rack without introducing unwanted distraction or thermal buildup.

This power and noise behavior also helps prolong component lifespan, particularly in warmer climates or enclosed cabinets, and supports use cases like 24/7 media server operation, offsite backups, or even small-scale CCTV archiving. Importantly, despite these low operating figures, the DS425+ still maintains stability and consistent throughput thanks to the efficiency of the J4125 processor and DSM’s power-aware service management. These characteristics, often underappreciated in specs alone, make it especially suitable for those who want reliable long-term uptime without high energy costs or acoustic interference.

Memory Limitations and Unorthodox Upgrade Path

The DS425+ comes with 2GB of DDR4 memory soldered directly to the motherboard, which is low by 2025 standards even for entry-level NAS devices. While it includes an additional memory slot that allows for the installation of a single 4GB module, the system officially supports a maximum of just 6GB of total RAM. This is an unusual and restrictive configuration, especially when many modern NAS devices now ship with 4GB or 8GB by default, and support 16GB or more—sometimes with dual-channel configurations for better performance. Synology’s strict validation policy also means that only their branded RAM (e.g. D4NESO-2666-4G) is fully supported, and installing third-party modules can trigger warnings in DSM or potentially void support coverage.

This memory ceiling becomes problematic when running DSM features that scale with RAM usage, such as Synology Drive, Snapshot Replication, Virtual Machine Manager, or Surveillance Station. As observed during testing, the DS425+ routinely used 27–38% of its available memory at idle, even without third-party packages installed. This is largely due to DSM’s intelligent memory caching system, which improves performance but leaves little headroom for user-defined workloads. Once additional services or multimedia indexing tasks are introduced, memory utilization climbs quickly, increasing the risk of slowdowns, swap usage, or outright service failure under peak demand.

For users who intend to deploy containers, host multiple camera feeds, or run even a small number of VMs, this limitation may lead to bottlenecks sooner than expected. It also makes the DS425+ a less viable choice for future expansion or multi-user environments. Unlike other NAS brands that allow full third-party upgrade freedom—or systems with dual RAM slots and broader capacity support—Synology’s enforced limitations here represent another example of the platform’s increasingly locked-down approach. For a system marketed to prosumers, the inability to exceed 6GB RAM comfortably is a notable technical and strategic constraint.

Integrated Graphics for Light Media Transcoding

Unlike many NAS units in this price tier, the DS425+ includes an Intel Celeron J4125 processor with integrated Intel UHD Graphics 600, which unlocks hardware-accelerated video decoding and transcoding in supported applications like Plex or Jellyfin. This makes the DS425+ one of the few Synology models in 2025 that still offers integrated GPU support out of the box, especially as newer Synology models with more recent CPUs have increasingly omitted integrated graphics. While the DS425+ is not intended to replace a dedicated media server, its GPU can significantly improve performance and efficiency for on-the-fly transcoding of formats like H.264 and H.265 (HEVC), particularly when streaming to remote clients with bandwidth constraints.

In real-world usage scenarios, this means the DS425+ can handle direct streaming and limited transcoding of 1080p content without overwhelming the CPU, provided the source formats are within the GPU’s supported codec list. During Plex testing, the DS425+ performed adequately with one or two 1080p transcodes running simultaneously, and was also able to manage basic 4K downscaling if the codec was natively supported by the hardware. For home users who have mixed devices—such as smart TVs, mobile devices, and tablets that vary in codec support—the presence of hardware transcoding offers improved flexibility without requiring as much manual conversion or format standardization of their media library.

Additionally, Synology’s native multimedia applications such as Surveillance Station and Synology Photos also benefit from GPU acceleration, helping speed up thumbnail generation, indexing, and playback, especially for high-resolution image and video collections. While raw CPU power in the DS425+ is modest by 2025 standards, the inclusion of integrated graphics helps balance out performance for lightweight graphical workloads and makes the system more viable as a general-purpose media hub. For users considering a NAS for Plex, family media streaming, or small business content previews, this capability adds meaningful value—especially since few modern Synology NAS devices still include Intel-based chips with iGPU support.

Outdated CPU Platform and Limited Performance Headroom

The DS425+ ships with the Intel Celeron J4125, a 4-core, 4-thread processor that was originally launched in late 2019. While it offers modest performance and includes integrated graphics, the J4125 is now significantly behind modern alternatives in both efficiency and raw compute power. Intel itself has discontinued the Celeron branding entirely, moving toward newer architectures like Alder Lake-N and Jasper Lake, which offer improved IPC (instructions per cycle), higher core/thread counts, and better thermal efficiency—all while retaining low power consumption. In comparison, the J4125’s aging 14nm Gemini Lake architecture struggles with heavier multitasking, especially when running services like virtual machines, surveillance workloads, or multiple Docker containers in parallel.

Synology has retained this CPU across several generations of its 2- and 4-bay Plus series models, which makes the DS425+ feel less like a generational upgrade and more like a lateral move. During performance testing, the unit handled DSM core tasks and multimedia indexing smoothly, but CPU load increased sharply under heavier tasks such as simultaneous Surveillance Station streams, Hyper Backup routines, or basic VM instances.

This limited headroom constrains the DS425+ to light-to-moderate workloads, and it can bottleneck more quickly than newer systems from other brands using more recent Intel N-series or AMD Ryzen Embedded CPUs. This is especially important as DSM continues to add new features that may increase background resource consumption over time.

Additionally, the CPU’s lack of support for modern instruction sets or features like AVX can limit compatibility with certain Docker containers or third-party applications that expect more recent hardware. While the DS425+ can serve well as a general-purpose file server or light media NAS, it’s not suited for users who anticipate growth into heavier mixed-use deployments. In a 2025 market where many similarly priced NAS units offer 6- or 8-core CPUs and PCIe Gen 3 or 4 support, the DS425+ feels constrained and unlikely to age well for users with evolving or expanding workloads.

Compact Form Factor with Versatile Storage Options

The DS425+ offers a space-efficient chassis design that houses four 3.5″/2.5″ SATA drive bays, along with two M.2 2280 NVMe SSD slots for caching. This provides a versatile platform for users who want flexible storage layouts without moving to a physically larger or more expensive rackmount or tower system.

The vertical orientation of the chassis, measuring just 166 x 199 x 223 mm, makes it easy to deploy the device in tight workspaces, shelving units, or beneath desks—ideal for small offices, home studios, or AV setups where space is at a premium. Despite its small footprint, the device retains full support for key RAID configurations including SHR, RAID 5/6/10, and JBOD, and offers hot-swappable access to the main drive bays for ease of maintenance.

The inclusion of two M.2 NVMe slots on the base of the unit allows users to improve performance through read/write caching without sacrificing primary drive bays. Although these M.2 slots are limited to Synology-verified SSDs and are not usable for storage pools, they can still offer significant boosts to random I/O performance in multi-user environments or when used with demanding workloads like Synology Drive or VM hosting. Combined with support for SSD TRIM and smart cache algorithms within DSM, the system can be tuned to optimize response times during high-access periods without introducing large amounts of memory overhead.

From a practical standpoint, this layout is beneficial for users managing multiple storage tiers, such as a mix of large-capacity HDDs for archiving and faster SSDs for active projects or virtual machines. Furthermore, the DS425+ supports volume expansion using larger capacity drives, RAID migration options (e.g. from Basic to RAID 5 or RAID 5 to RAID 6), and up to 32 internal volumes, giving users enough headroom for future scaling. These features, while standard in DSM, are fully supported in this chassis and make it easier to adapt the NAS as storage needs evolve—without the need to start from scratch or invest in a new enclosure.

Limited I/O and Underwhelming Connectivity for the Price

While the DS425+ introduces a 2.5GbE network port alongside a legacy 1GbE port, the rest of its I/O configuration is relatively limited and arguably outdated compared to competitors in its price range. The system includes just two USB 3.2 Gen 1 ports, both of which operate at 5Gbps rather than the more modern 10Gbps (Gen 2) speeds that are increasingly common in 2025. There is no SD card slot, no eSATA or PCIe expansion slot, and no HDMI output, all of which are features now appearing on rival NAS systems from QNAP, TerraMaster, and UGREEN—even at similar or lower price points. These omissions restrict how the device can be expanded or integrated into more complex workflows, such as direct-attached backup targets, external GPU support, or quick media ingestion.

The presence of only a single 2.5GbE port also imposes a bottleneck for users wanting to make full use of SSD caching or high-throughput RAID configurations. There is no support for link aggregation, as the 1GbE and 2.5GbE ports cannot be bonded in a meaningful way, and the system lacks support for 5GbE or 10GbE—either onboard or via expansion. In scenarios where large video files, virtual machine images, or multiple users are simultaneously accessing data, the NAS may become network-bound more quickly than other models with multi-GbE or SFP+ connectivity.

Furthermore, while DSM offers support for USB peripherals such as external drives and UPS devices, the limited port count and bandwidth mean there is little headroom for simultaneous external expansions, and the brand limits the support of USB peripherals for security reasons. For example, attaching both an external drive and a USB-connected UPS may require unplugging one to rotate in another device. This may not impact casual home users, but for power users managing workflows like video editing, offsite rotation backups, or multi-location file sync, this level of I/O flexibility feels dated. When factoring in the DS425+’s pricing, which places it near many NAS models with more expansive I/O, this minimalism can be a significant drawback.

Strong Security Framework and Proactive Vulnerability Management

The DS425+ benefits from Synology’s broader emphasis on security, offering a robust framework for data protection, secure remote access, and proactive threat mitigation. DSM includes built-in tools such as firewall rules, auto-blocking of suspicious IPs, HTTPS configuration, and native integration with Let’s Encrypt for SSL certificates. Two-factor authentication (2FA) can be enforced per user or globally, and built-in VPN server options (including OpenVPN and L2TP/IPSec) provide secure tunnels for remote workers or offsite access. For businesses or power users hosting sensitive data, the inclusion of AES-NI hardware encryption ensures efficient at-rest protection without drastically impacting system performance.

What sets Synology apart is its ongoing commitment to security research and response. The company operates a public-facing Product Security Incident Response Team (PSIRT) and regularly updates a detailed security advisory page disclosing vulnerabilities and their mitigations. Synology also participates in Pwn2Own, a white-hat hacking competition, and runs internal bug bounty programs to uncover and patch exploits before they are discovered in the wild. This culture of transparency and preemptive action is especially valuable as NAS devices become more frequently targeted by malware and ransomware threats, particularly those exposed to the internet or used in hybrid cloud workflows.

Additionally, many DSM apps include granular permission management, audit logs, and user-based access rules, giving administrators tight control over file shares, backup targets, and service access. Synology’s Hybrid Share and Cloud Sync tools support end-to-end encryption and offer options to decouple cloud storage keys from the local system, further strengthening data sovereignty. For users concerned with long-term viability and platform trust, Synology’s structured and well-documented security practices help the DS425+ stand out against competitors that may offer more hardware but less attention to software and infrastructure hardening. This makes it a viable choice for users prioritizing data safety in either personal or professional contexts.

Questionable Long-Term Value Amid Shifting Synology Strategy

Another concern with the DS425+ is its position within Synology’s evolving product strategy, which raises questions about long-term support and ecosystem focus. Synology has recently been expanding its BeeStation and BeeStation Plus lines—pre-populated, user-friendly NAS solutions that share similar hardware (in some cases, the same J4125 CPU), but are bundled with drives and offer a simplified DSM variant tailored for general consumers. These systems, while more limited in scope, are marketed as turnkey alternatives with lower pricing and fewer user-configurable components. The DS425+, by contrast, sits awkwardly between Synology’s increasingly restrictive hardware requirements and the emerging shift toward closed, fully managed platforms.

This change in trajectory creates uncertainty for prospective buyers looking for a long-term investment. If Synology continues prioritizing its proprietary hardware and software pairings, users who prefer modularity, drive freedom, or advanced customization may find themselves increasingly constrained. As already noted, the DS425+ enforces tight compatibility rules, limits memory expansion, and restricts NVMe usage to caching only. At the same time, Synology is streamlining its portfolio around devices with even stricter limitations but more mass-market appeal. This raises the possibility that traditional “Plus” models like the DS425+ may be sidelined or see fewer feature updates in future DSM releases, as Synology shifts development toward more controlled environments.

From a cost perspective, the DS425+ is priced around $519, placing it uncomfortably close to more powerful third-party NAS systems that offer better CPUs, more RAM, and greater I/O flexibility. Competing brands frequently offer 4-bay systems with modern N-series Intel processors or embedded AMD chips, 8GB+ of memory, and faster networking, often for the same or lower price. As a result, the DS425+ risks being outclassed not only by its competition, but by Synology’s own growing lineup of prepackaged solutions. Users investing in the DS425+ today may find themselves limited not just by current specs, but by an ecosystem slowly drifting away from the prosumer and enthusiast segment this model was originally meant to serve.

Synology DS425+ NAS Review – Conclusion and Verdict

The Synology DS425+ presents a mixed proposition in 2025. On one hand, it remains a competent 4-bay NAS solution for users prioritizing software integration, low power operation, and quiet, reliable 24/7 usage. Its support for DSM 7.2 and the full suite of Synology applications—ranging from Active Backup to Surveillance Station and Synology Drive—makes it a strong turnkey platform for general-purpose storage, backup, and multimedia needs. Integrated graphics give it an edge in light media streaming scenarios, and its support for M.2 NVMe caching allows for performance optimization without occupying drive bays. It’s a well-built device that continues to “just work,” particularly in home and small office setups where reliability, simplicity, and refined software matter more than raw horsepower.

However, these strengths are increasingly offset by hardware limitations and Synology’s increasingly restrictive ecosystem. The soldered 2GB of RAM, locked 6GB memory ceiling, outdated CPU, limited I/O, and especially the enforced use of Synology-only drives all hinder flexibility and long-term value. When compared to similarly priced alternatives from competing NAS vendors—many of which offer newer processors, faster ports, and full hardware freedom—the DS425+ can feel constrained and overpriced. In addition, Synology’s expanding focus on pre-populated BeeStation devices suggests a possible shift away from traditional DIY-friendly models like this one. For users who are already invested in the Synology ecosystem or who value DSM above all else, the DS425+ may still be a worthwhile buy. But for those seeking hardware scalability, third-party compatibility, or better price-to-performance, it may be worth considering other options or waiting to see how Synology’s roadmap evolves.

Quick Summary of the Synology DS1825+ NAS

Synology DS1825+ NAS Review HERE

The Synology DS1825+ is an 8-bay desktop NAS that marks a significant shift in the company’s approach to hardware and compatibility. Equipped with the AMD Ryzen Embedded V1500B processor—a 4-core, 8-thread chip running at 2.2GHz —this system balances power efficiency with performance across general file operations, virtualization, and media hosting. It includes support for up to 32GB of ECC DDR5 memory (2x SODIMM, arriving with 8GB by default), two M.2 NVMe slots for Synology-only SSD caching, and an onboard 10GbE port alongside three USB 3.2 Gen 1 ports. However, Synology’s controversial locked ecosystem continues here, restricting users to only Synology-branded drives for full support and access to storage pools, along with limited use of the NVMe bays strictly for cache, not storage.

While its internal hardware is more capable than previous Plus series models, the DS1825+ removes several features seen in past units. By default, it arrives with 2x 2.5GbE network ports, with the option to scale upto 10GbE with the use of a 1st party upgrade PCIe card, but at this pricepoint many users wuld expect 10GbE as standard. The shift to DSM 7.2 brings a refined software experience, including native Active Backup for Business, Hyper Backup, Surveillance Station, and full Docker support. However, DSM’s increasing reliance on Synology’s own hardware and subscription services, such as C2 Surveillance Proxy and Synology Drive Server, makes it harder for users to customize or expand without sticking to Synology’s ecosystem. Overall, the DS1825+ is best suited for users who want an integrated, secure, and reliable NAS experience with minimal manual setup, provided they are comfortable with the tighter hardware constraints.

Quick Summary of the UGREEN DXP8800 PLUS NAS

UGREEN DXP8800 PLUS NAS Review HERE

The UGREEN DXP8800 Plus is an 8-bay NAS solution that positions itself as a powerful, open-platform alternative for users seeking greater control over hardware and software customization. At the heart of the system is the 8-core, 16-thread Intel Core i5-1235U processor, paired with 8GB of DDR5 memory (expandable up to 64GB), but lacks support for ECC memory. Unlike its Synology counterpart, the DXP8800 Plus supports a much wider range of third-party hard drives and SSDs, and offers 2x Gen 4×4 M.2 NVMe slots that can be used not only for cache but also for primary or tiered storage, depending on the user’s operating system. This flexibility is backed by a user-serviceable layout and BIOS access, which allows full compatibility with alternative NAS OS options such as TrueNAS SCALE, UnRAID, or OpenMediaVault.

Connectivity is another area where the DXP8800 Plus stands out. It features two native 10GbE (RJ45) ports, two 2.5GbE ports, and dual USB4/Thunderbolt 4 ports, dramatically expanding external storage, docking, and display capabilities. This, combined with onboard HDMI output and front-accessible USB 3.2 ports, makes it far more versatile for media creation, backup workflows, and even lightweight workstation use. However, the DXP8800 Plus does not come with a polished first-party NAS operating system—UGREEN’s UGOS Pro remains in early stages, and lacks many of the mature backup, surveillance, and cloud services found in DSM. As such, the DXP8800 Plus is ideal for tech-savvy users who value open architecture, higher hardware flexibility, and self-managed software ecosystems over out-of-the-box turnkey simplicity.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Design and Storage

The Synology DS1825+ maintains the familiar chassis style used in the Plus series, combining functionality with conservative aesthetics. It features a full-sized 8-bay front panel with lockable trays, designed for tool-less insertion of 3.5” SATA drives and optional 2.5” adapters. The main body is a mix of steel and plastic, with a focus on rigidity and reduced vibration. The system lacks any onboard display or LCD, offering only basic LED indicators for system status, drive activity, and alerts, which may frustrate users seeking at-a-glance diagnostics. Access to internal components like the DDR5 ECC RAM and dual M.2 NVMe slots requires removing the top cover and internal caddy brackets, which isn’t as straightforward as it could be—especially given that the NVMe slots are only usable for cache and require Synology-branded drives. Thermal management relies on dual 120mm rear-mounted fans, which operate quietly but are non-replaceable without voiding warranty due to the proprietary fan harness. Physically, the NAS is slightly larger than competing 8-bay units and lacks rubberized feet or vibration isolation, which may be relevant for users placing it on shared work surfaces or desks.

The UGREEN DXP8800 Plus delivers a contrasting design focused on space efficiency, cooling, and user-accessibility. The NAS is housed in a durable metal shell with perforated side panels and a high-density internal structure. Despite its smaller footprint, it manages to accommodate eight SATA bays, two 4X4 M.2 NVMe slots, two SODIMM slots, and active cooling—all while remaining user-serviceable with just a standard screwdriver. The hot-swap trays are spring-loaded and support tool-less 3.5” drives or 2.5” drives via included screws. Access to RAM and SSD slots is streamlined through a simple internal partition design that doesn’t require full disassembly, making upgrades significantly faster than on the DS1825+. The rear exhaust fan is larger than expected for a device this compact, and although thermals are generally within acceptable limits, our testing showed that M.2 SSDs running at PCIe Gen 3 speeds did reach over 65°C during sustained I/O, especially when mounted without aftermarket heatsinks. Unlike Synology, UGREEN includes front-mounted USB 3.2 Gen 2 ports (Type-A and Type-C), ideal for creators and users who frequently move large projects or footage onto the system using direct-attached storage.

When it comes to storage flexibility, the differences are stark. Synology’s DS1825+ enforces a strict hardware compatibility policy, where only Synology-certified HDDs (such as the HAT5300) and SSDs (SAT5200 or SNV3410/3510) are officially supported. Drives outside this list may trigger warnings, be ineligible for pools, or lose access to SMART health readings. NVMe drives cannot be used for storage volumes at all and are locked to caching roles only. These restrictions are enforced by DSM 7.2+ and persist even with the system fully updated.

By contrast, the UGREEN DXP8800 Plus places no such limits. Any SATA or NVMe drive can be used, and users can create pools across mixed-capacity and mixed-brand disks, including enterprise-grade drives. Storage volumes can be configured freely in supported OS environments, and the two M.2 slots can act as primary storage, tiered ZFS vdevs, or cache depending on the OS—TrueNAS SCALE, for instance, recognized all M.2 drives and allowed custom pool creation without issue. This makes UGREEN’s system more attractive to users with existing drives or specific ZFS/Btrfs layouts in mind.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Internal Hardware

he Synology DS1825+ is built around the AMD Ryzen V1500B processor, a 4-core, 8-thread embedded SoC designed specifically for NAS and server workloads. With a fixed base clock of 2.2GHz and no boost functionality, this Zen-based CPU focuses on stability, multi-threaded efficiency, and low power consumption, making it well-suited for consistent background operations like file serving, multi-client backups, and large-scale storage array management. The chip includes AES-NI support for hardware encryption acceleration and offers full compatibility with DSM’s virtualization stack, including Docker and Synology’s Virtual Machine Manager. However, the V1500B lacks an integrated GPU, and the DS1825+ does not support hardware transcoding, making it unsuitable for Plex or media applications that rely on real-time video encoding unless offloaded to cloud services like Synology C2. It’s a reliable and mature processor choice, albeit one that prioritizes stability over flexibility or raw speed.

The DS1825+ ships with 8GB of ECC DDR4 memory (1x SODIMM) installed, with support for up to 32GB across two slots, and ECC is supported on both official and some compatible third-party modules. The internal layout, however, is relatively restrictive. The memory and M.2 slots require tray removal and partial disassembly to access. Synology includes two M.2 NVMe slots that operate at PCIe Gen 3×4, but DSM only allows them to be used for read/write caching and only with Synology SNV3410 or SNV3510 SSDs. These slots are not available for storage pool creation or system boot, regardless of the SSD used. There is no PCIe slot or BIOS access, making this a closed system that enforces Synology’s validation model tightly. While this approach ensures stability, it limits performance tuning and locks users into higher-priced branded components.

The UGREEN DXP8800 Plus uses an Intel Core i5-1235U, a hybrid 10-core (2 performance, 8 efficiency), 12-thread mobile CPU built on the Alder Lake-U architecture. With a boost clock up to 4.4GHz and integrated Intel Xe graphics, it offers both multi-threaded efficiency and hardware video transcoding support via Quick Sync. This is ideal for users running Plex, Jellyfin, or AI-based video analysis locally. The system ships with 8GB of non-ECC DDR4 memory, expandable to 64GB, using standard SODIMM slots. UGREEN’s internal board features 2x M.2 NVMe slots operating at PCIe Gen 4×4 speeds, offering significantly more bandwidth than Synology’s Gen 3 slots. These SSDs can be used for boot, storage pools, or cache, and the system supports a wide range of third-party drives without warnings or restrictions. BIOS access is fully available, allowing installation of operating systems like TrueNAS, UnRAID, or Proxmox. UGREEN’s internal hardware favors openness and customizability, providing users with direct control over performance, expansion, and component choice—at the cost of requiring more technical expertise.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Ports and Connections

The Synology DS1825+ delivers a modest and business-focused range of connectivity options, designed primarily for reliability and integration within an IT-managed environment. It includes 2x 2.5GbE RJ-45 LAN ports, offering basic link aggregation or dual-network failover functionality. While this offers faster-than-Gigabit throughput, the lack of 10GbE out of the box may be limiting for users working with large media files or virtualization workloads, particularly in comparison to other 2025 systems.

The system provides 3x USB 3.2 Gen 1 (5Gbps) Type-A ports, all located on the rear, suitable for UPS integration, external storage, or compatible backup devices. In terms of expansion, Synology includes 2x USB Type-C ports, but these are reserved exclusively for connecting official DX525 expansion units. They do not support data transfer, peripherals, or USB-C accessories and serve only as proprietary expansion interfaces. No HDMI, DisplayPort, or audio outputs are included, and there is no SD card reader. This reinforces Synology’s design philosophy: operate headlessly, manage remotely, and keep the system within the bounds of their validated ecosystem.

In contrast, the UGREEN DXP8800 Plus positions itself as a fully-featured, hybrid-use NAS platform with wide-ranging I/O options for prosumers and professionals. It features 2x 10GbE RJ-45 LAN ports—a clear advantage over Synology’s 2.5GbE setup—offering significantly more bandwidth for media editing, VM hosts, or multi-user environments. On the front, UGREEN includes 2x Thunderbolt 4 (40Gbps) ports, which double as high-speed USB-C for peripherals, external drives, or even eGPU enclosures in supported OS setups. The rear provides 2x USB-A ports at 10Gbps, plus 2x USB 2.0 ports, allowing backward-compatible peripheral support. For display, the system includes 1x HDMI port with 8K output support, connected via Intel’s Xe iGPU, as well as a high-speed SD 4.0 card reader—a particularly valuable addition for content creators offloading camera media directly to the NAS. There is also a PCIe x4 slot for optional hardware expansion. This broad I/O layout enables the DXP8800 Plus to function as a headless NAS, a media server, or even a workstation replacement, depending on the OS you choose to run.

The gap in connectivity between these two NAS systems reflects their broader design philosophies. Synology has deliberately kept the DS1825+ minimal, standardized, and tightly integrated with its ecosystem, which enhances long-term support and serviceability but limits flexibility. UGREEN, on the other hand, offers extensive general-purpose ports that cater to a wider range of workflows—especially for users running Windows, Proxmox, TrueNAS, or virtualized environments. Whether it’s direct media ingestion via SD card, high-speed expansion through Thunderbolt, or dual 10GbE networking, the DXP8800 Plus outpaces the DS1825+ in almost every I/O category. However, this flexibility comes with the expectation that the user is comfortable with open-platform system management and a DIY-style deployment model.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Software and Services

The Synology DS1825+ runs on DSM 7.2, Synology’s mature and widely respected NAS operating system. DSM offers a broad ecosystem of native applications and services, including advanced storage management, multi-tiered backup solutions, virtual machine hosting, and comprehensive multimedia support. Key built-in tools such as Synology Drive, Hyper Backup, Active Backup for Business, Surveillance Station, and Synology Photos provide enterprise-grade data handling in a highly polished interface.

DSM also includes Snapshot Replication with Btrfs, granular folder/file-level restore, and Active Directory integration. Importantly, DSM supports features like Windows ACL permissions, Samba v4, WORM file locking, and two-factor authentication by default, with Synology’s C2 platform offering cloud sync, identity management, and secure backup options. However, DSM has increasingly tied deeper functionality (e.g., certain security tools and snapshots) to Synology-branded storage and expansion hardware, with third-party drive warnings now appearing by default.

UGREEN’s DXP8800 Plus runs UGOS Pro, a Linux-based operating system developed in-house. Now one year into active deployment, UGOS Pro has matured substantially with ongoing updates and wider feature support. The interface is clean and web-accessible, and recent updates have added core NAS functions previously missing. As of the latest firmware, Docker, virtual machine creation, and Jellyfin media server are all natively supported via one-click installs.

Importantly, iSCSI support was also added, addressing a key omission for enterprise or VMware users. 2-factor authentication (2FA) is now present, and security protocols include IP/MAC-level blocking, custom firewall rules, and access control policies. While UGREEN still lacks the depth of anti-ransomware protection found in DSM or QNAP’s QuFirewall, the fundamentals have improved dramatically. Local-only AI services for photo indexing and object recognition have also been refined, with user-selectable models running without internet access.

Where DSM excels in deep integration and business-class reliability, UGOS Pro stands out for its openness and responsiveness to user feedback. Users can enable SSH, customize OS-level settings, and even install TrueNAS, UnRAID, or Proxmox without voiding the warranty, as UGREEN has opted for an open-platform approach.

UGOS also supports Windows file services (SMB), NFS, and web-based file managers, though its permissions system and UI are still somewhat basic compared to DSM. Synology’s first-party software tends to offer higher polish, more documentation, and broader cross-platform support, particularly in cloud-integrated services, whereas UGOS is catching up in functional breadth but remains relatively limited in automation and long-term software ecosystem depth.

Both platforms include mobile apps and browser-based remote access, but Synology’s remote access via QuickConnect is significantly more user-friendly and secure out-of-the-box, while UGREEN’s remote services are best replaced or supplemented by Tailscale, Cloudflare Tunnel, or similar tools. Synology’s Surveillance Station also has years of development behind it with support for hundreds of IP cameras, whereas UGREEN does not yet include native surveillance software in UGOS Pro.

For users seeking a media-focused setup, UGOS offers a good local multimedia experience via Jellyfin, while DSM supports Plex and Video Station (with transcoding limitations depending on CPU). Ultimately, Synology’s DSM remains the more robust, enterprise-ready option, while UGOS Pro presents a highly promising and increasingly competitive open alternative that still favors self-managed users.

Synology DS1825+ vs UGREEN DXP8800 PLUS NAS – Verdict and Conclusion

The Synology DS1825+ remains a compelling choice for users prioritizing reliability, software integration, and long-term support. With the proven DSM 7.2 platform, it offers enterprise-grade tools for file management, backup, virtual machines, and surveillance. Features like Snapshot Replication, C2 cloud integration, and Active Backup for Business provide peace of mind for professionals who want a turnkey experience with minimal maintenance. Although hardware specs such as the Ryzen V1500B CPU and dual 2.5GbE ports might seem modest compared to rivals, they are more than adequate for office environments, multi-user file sharing, and even light virtualization. That said, its increasing reliance on Synology-branded drives and accessories, as well as its lack of GPU support and M.2 NVMe flexibility, could be frustrating for DIY enthusiasts or media-focused users.

By contrast, the UGREEN DXP8800 Plus is a hardware-forward NAS that emphasizes performance, bandwidth, and customization. With a 12-core Intel Core i5-1235U CPU, dual 10GbE, PCIe expandability, and full-speed Gen 4 NVMe slots, it is built for workloads that demand raw power—media servers, high-speed backups, AI indexing, and even containerized apps via Docker. UGOS Pro has matured considerably over the last year, with new features like iSCSI, 2FA, VM hosting, and Jellyfin support making it much more viable than at launch. Still, while UGREEN’s open architecture and wider SSD/drive compatibility are a strength, its software ecosystem isn’t yet as refined or battle-tested as Synology’s DSM, especially for more security-sensitive or compliance-bound environments. Surveillance features and enterprise-level monitoring tools are also still missing or immature in comparison.

In short, the Synology DS1825+ is best suited for SMBs, IT administrators, or content creators who want a dependable, low-maintenance NAS with rich native features and strong vendor support, especially where third-party remote access is limited or not desired. On the other hand, the UGREEN DXP8800 Plus is ideal for prosumers, media professionals, and tech-savvy users who want maximum hardware flexibility, faster internal/external transfer speeds, and the freedom to customize their NAS at the OS level, even if that means dealing with a slightly rougher software experience. If ease of use, documentation, and long-term stability are your priorities, the DS1825+ remains a safe bet. But if you’re looking for value in performance per dollar, more openness, and higher bandwidth potential, the DXP8800 Plus offers a lot for the price.

AI Console for Synology Mail Plus and Synology Office – But Should You Use It?

Note -Thanks again to Daniel from Germany for all his support and assistance for this video. Visit his site HERE

Synology has introduced a new software package called AI Console, aimed at integrating third-party AI and large language model (LLM) services directly into select Synology productivity applications. The package is available on devices running DSM 7.2 or later and supports only certain x86-64 NAS models, reflecting the higher processing and memory requirements of AI workloads.

Rather than running its own local AI engine, Synology provides a centralised management tool for connecting to established AI providers, including OpenAI, Azure OpenAI, Google Gemini via AI Studio or Vertex AI, Amazon Bedrock, and Baidu AI Cloud. Once linked using the administrator’s API key, these services can be used within Synology MailPlus and Synology Office to perform tasks such as summarising long emails, generating responses, translating text, adjusting tone, and producing refined document content.

The AI Console is designed with administration and control in mind. It allows system managers to configure access on a per-package basis, selectively enabling or excluding AI features for specific users or groups. Advanced options include setting daily or per-minute token limits for each user to control consumption and manage costs, as usage charges are determined by the chosen AI provider rather than Synology itself. For privacy protection, the Console supports a de-identification process that can mask predefined categories of sensitive data before prompts are sent to an AI provider, with the original data restored after the response is received.

Administrators can monitor adoption and usage trends through transaction logs, which capture request details such as timestamps, IP addresses, API models used, and token counts, alongside admin logs that record configuration changes. While the AI Console does not add AI functionality to all DSM applications, it focuses on extending the business-oriented MailPlus and Office suite. However, this is not a move that will please all Synology owners or buyers, as some value their NAS primarily for complete local data control and may view any cloud-connected AI integration as an unnecessary or risky addition.

Why is Synology AI Console So Contentious?

The idea of adding AI functionality to a NAS is divisive because many users adopt these systems specifically to avoid reliance on cloud-based services. A key selling point of a Synology NAS has long been the ability to store, process, and back up data entirely within the user’s own premises, retaining full control over where that data resides and who can access it.

By design, the Synology AI Console connects to external AI providers through API calls, meaning that text-based content from MailPlus or Office documents is transmitted to third-party servers for processing. Even with encryption in transit and privacy safeguards such as de-identification, this external dependency conflicts with the expectations of users who purchased a NAS to minimise exposure to external networks. This tension is heightened by the fact that the AI operations do not run locally on the NAS hardware, which for some buyers undermines the appeal of integrating AI into a device marketed for self-contained operation.

Another factor making AI use contentious is the trust and compliance aspect. Many NAS deployments are in small businesses, professional environments, or home offices handling sensitive material. Sending even anonymised extracts of communications or documents to an external service raises compliance questions for organisations bound by strict data protection rules, especially in regulated industries such as healthcare, finance, or legal services.

While the AI Console provides administrative controls, auditing tools, and the option to disable AI entirely for certain users or packages, the underlying reality remains that data is leaving the local network for processing. This creates a fundamental divide between those who welcome AI for its productivity benefits and those who see any form of off-device data processing as incompatible with the core value proposition of a private NAS.

What Security Provisions Have Synology Put in Place?

Synology’s AI Console incorporates multiple layers of control to reduce the risks associated with transmitting data to third-party AI providers. API keys for connected AI services are stored locally on the NAS rather than in the cloud, and all requests are sent directly from the device to the selected AI provider. Administrators can remove these keys at any time, immediately severing the connection. The system allows AI access to be enabled or disabled at the package level, with the option to exclude specific users or groups entirely. To prevent uncontrolled consumption, administrators can set token rate limits per user, measured either per minute or per day. Transaction logs record each AI request with details such as timestamp, source IP address, user account, API model used, and token usage, while admin logs document any configuration changes. This creates a verifiable audit trail for compliance and internal review.

Key security provisions include:

• Local storage of API keys, with no cloud-based key management.

• Direct communication between the NAS and the AI provider, bypassing Synology’s own servers.

• Ability to revoke API access instantly by deleting stored keys.

• Per-package AI enable/disable controls, with user and group-level exclusions.

• Token rate limiting to control per-user API usage.

• Detailed transaction logs for all AI requests.

• Administrative logs for configuration changes.

• Optional logging of request inputs and outputs for auditing.

For added privacy, Synology offers a de-identification feature that can mask selected categories of sensitive data before they are transmitted to the AI provider, restoring the original information once the processed output is returned. This feature can identify and anonymise common identifiers such as names, email addresses, IP addresses, banking details, and various country-specific personal or business numbers. De-identification relies on a combination of AI-driven semantic analysis and predefined regular expression rules, giving administrators control over which data types are masked. It requires the installation of the Container Manager package and a minimum of 8 GB of RAM, with each enabled language model consuming roughly 1 GB of memory. Although Synology notes that de-identification cannot guarantee 100% masking, the mechanism is intended to significantly reduce the chance of exposing sensitive details during AI processing.

Synology Mail Plus and AI Console Integration

When enabled for Synology MailPlus, the AI Console provides a set of functions aimed at improving email efficiency through automated text processing. Within the MailPlus interface, users can generate short or detailed summaries of incoming emails, which can help quickly assess lengthy messages without reading them in full. The AI assistant can also draft replies based on user instructions, with options to adjust tone, length, and formality, or translate the response into a supported language. All AI processing is text-based, with attachments excluded from transmission to the AI provider. The system also supports “Help me write” prompts directly within the reply editor, allowing for quick generation of tailored responses that can be inserted and then edited before sending. Importantly, these capabilities are only available to users granted AI permissions by the administrator, and all actions are recorded in transaction logs for review.

The integration offers multiple editing refinements, including making a message more formal or casual, shortening or lengthening text, and translating to or from languages supported by the connected AI model. Users can also rephrase replies entirely or request alternative drafts. Although these capabilities are similar to features found in other email platforms that integrate AI, the implementation within MailPlus is designed to remain under the control of the NAS administrator, with optional de-identification masking personal data before it is sent to the provider. Responses are generated by the third-party AI service configured in AI Console, and processing occurs only when the user explicitly invokes an AI function, avoiding any automated sending of content without user action.

From a functional perspective, MailPlus AI integration is targeted primarily at professional or business environments that run their own Synology-hosted mail server. It can streamline response drafting, reduce time spent on routine communication, and support multilingual correspondence. However, the scope is currently limited to text-based tasks, with no AI-driven attachment analysis, advanced categorisation, sentiment detection, or automated email sorting included. The feature set also lacks customisable style profiles beyond the basic tone and length adjustments, meaning more specific brand or sector language must still be applied manually. The value for each organisation will depend on how frequently staff interact with longer, more complex emails, and whether the trade-off of involving an external AI service aligns with internal data handling policies and compliance requirements.

Synology Office and AI Console Integration

In Synology Office, AI Console integration extends across the suite’s document, spreadsheet, and presentation tools, embedding AI-assisted functions within the existing editing interface. In documents, the AI assistant can summarise entire files, rewrite selected sections, adjust tone, translate content, or improve grammar. These actions can be applied either through a right-click contextual menu or via a dedicated AI sidebar that displays results alongside the original content. Users can choose to insert AI-generated revisions directly into the file or keep them separate for manual comparison. The system maintains Office’s existing version history, meaning any AI-driven edits can be rolled back without data loss.

In spreadsheets, the integration is aimed at assisting with formula comprehension and basic data interpretation. Users can request explanations of specific formulas, generate new formulas from plain-language prompts, or run simple calculations without manually writing functions. The AI can also produce summaries of table data, although its analytical depth is limited compared to dedicated business intelligence tools. As with documents, processing is restricted to text-based content; the system does not transmit embedded images or charts to the AI provider. Administrators can control whether AI features are available in spreadsheets, allowing them to be enabled for certain user groups while remaining disabled for others.

For presentations, the AI can refine slide text, translate content, or expand bullet points into fuller sentences, making it useful for producing alternate versions of existing material. The functionality mirrors what is available in documents, with tone and length adjustments as well as grammar checks. However, it does not currently create entirely new slide decks or visual layouts from prompts. The processing workflow remains the same across all Office formats: only when a user explicitly triggers an AI action is the relevant text sent to the configured provider, and all requests are recorded in the AI Console’s transaction logs.

Overall, the Synology Office integration offers consistent AI tools across its core applications, focusing on editorial and language-based support rather than data-driven automation. While the scope is narrower than AI-enabled features in some third-party office suites, the implementation maintains administrative control and allows for selective deployment, making it adaptable to environments where privacy considerations limit the use of external services.

What Features of AI/LLM Are Not Present?

Although the Synology AI Console brings AI-assisted functions to MailPlus and Office, it does not provide the same breadth of capabilities found in some competing platforms. There is no locally hosted AI model option, meaning all processing is dependent on a live connection to a third-party provider. As a result, the system lacks offline functionality, GPU-accelerated local workloads, or support for running open-source LLMs within the NAS environment. In practical terms, this means that all AI operations involve external processing, which may not suit users who require fully on-premises data handling.

Beyond the infrastructure level, several functional gaps remain. The integration does not extend to all DSM applications, omitting areas such as File Station, Photo Station, Synology Photos, and Surveillance Station. Within MailPlus and Office, the AI features are focused on text editing and basic summarisation rather than broader automation. There is no built-in capability for sentiment analysis, advanced data analytics, automatic categorisation, or content generation from large datasets. Similarly, the AI Console does not currently allow multi-step task automation or integration with custom scripts, limiting its use to predefined actions within the supported productivity tools.

Is Synology AI Console Safe?

From a technical and administrative perspective, Synology has implemented several measures to protect data when using the AI Console. API keys are stored locally on the NAS, and requests to AI providers are sent directly from the device rather than passing through Synology-operated servers. Administrators can limit access to specific packages, exclude selected users or groups, set token usage caps, and monitor all AI interactions through detailed logs. For additional privacy, the optional de-identification feature can mask sensitive details such as personal identifiers, banking information, and IP addresses before prompts are transmitted, restoring them only after the AI provider returns a response.

However, the safety of the AI Console ultimately depends on the chosen AI provider and the user’s own policies. All processing occurs on the provider’s infrastructure, meaning data leaves the local network whenever AI features are used. Even with encryption and masking in place, this external dependency may be unacceptable in environments with strict regulatory requirements or where complete local control is mandatory. While Synology provides the tools to minimise risk and monitor usage, it is the administrator’s responsibility to select a compliant provider, configure de-identification appropriately, and ensure that AI features are only enabled where the security implications are fully understood.

Feature-Rich DSM Software and Integrated Services

One of the strongest arguments in favor of the DS225+ is its inclusion of Synology’s DiskStation Manager (DSM), widely recognized as one of the most polished NAS operating systems on the market. DSM 7.2 runs natively on the DS225+ and includes a comprehensive suite of first-party tools designed for file management, backup, synchronization, collaboration, and multimedia.

Applications such as Active Backup for Business enable full system imaging and granular backups for Windows and Linux clients, while Hyper Backup supports encrypted, versioned backups to remote Synology NAS, USB drives, or public cloud platforms. These tools are license-free and integrate tightly with DSM’s centralized control panel and task scheduler, making them practical for individuals and small teams alike.

The DS225+ also supports Snapshot Replication, allowing users to create fast, low-overhead restore points across shared folders or entire volumes. This is especially useful for protecting data against accidental deletion or ransomware threats. Multimedia services such as Synology Photos and Video Station are included, with support for AI-driven features like facial and object recognition—provided the RAM is upgraded to at least 4GB.

Additionally, users can deploy lightweight productivity services such as Synology Drive, Chat, and Office, all of which are accessible via browser or mobile apps. While the DS225+ is limited to 2 bays, it still benefits from full access to Synology’s software stack, giving users enterprise-grade functionality in a compact and relatively affordable unit.

Locked Drive Compatibility Limits Flexibility and Upgrade Options

A major drawback of the DS225+ is Synology’s increasingly rigid stance on drive compatibility, particularly with its 2025 product generation. At launch, the DS225+ only officially supports Synology-branded HDDs and SSDs, including the HAT5300 and SAT5200 series. While these drives offer solid performance and enterprise-grade validation, they are often more expensive than third-party alternatives and far less widely available in retail markets.

More critically, DSM may block or degrade functionality if users install unsupported drives—such as WD Red, Seagate IronWolf, or Toshiba N300—even if those drives meet technical requirements. This includes disabling RAID creation, expansion, and in some cases even volume initialization.

For users hoping to reuse drives from older systems or build cost-effective arrays with commodity drives, this presents a serious limitation. The policy effectively turns the DS225+ into a semi-proprietary system where basic RAID features and DSM warnings depend on purchasing Synology-approved hardware.

While it’s possible the compatibility list may expand in the future, as of July 2025, this restriction creates significant friction for DIY users or small offices managing mixed storage fleets. It also undermines the flexibility that has traditionally been one of Synology’s key advantages over more locked-down storage ecosystems. Users seeking the freedom to choose drives based on price, warranty, or local availability will find the DS225+ ecosystem increasingly restrictive.

Exceptionally Low Power Consumption and Quiet Operation

The DS225+ is particularly well-suited for 24/7 deployment in environments where power efficiency and noise are concerns, such as home offices, media rooms, or shared living spaces. In real-world usage, the system consumes just 16.98 watts during access and drops as low as 6.08 watts in HDD hibernation, making it one of the most energy-efficient 2-bay NAS systems in its class.

This low draw is aided by the efficient Intel J4125 processor and a single 92mm system fan that manages thermals without overcompensating. During testing, the DS225+ maintained component temperatures of 32°C–37°C even under sustained moderate CPU and disk activity, confirming that the chassis design and airflow are well-optimized for the thermal envelope.

In terms of acoustics, the DS225+ is also ideal for quiet setups. It produces just 19.6 dB(A) of noise at idle—barely above ambient background levels—and remains quiet even under drive access or medium fan profiles. This makes it an appealing choice for use in proximity to desks, entertainment setups, or even bedrooms, without becoming a source of distraction. The adjustable fan modes (Full-Speed, Cool, and Quiet) can be fine-tuned in DSM, allowing users to prioritize either silence or cooling based on workload and ambient conditions. For users who want a reliable NAS that can operate continuously without noticeable noise or energy penalties, the DS225+ delivers an efficient and unobtrusive experience.

Aging Intel Celeron J4125 CPU Limits Future-Proofing

The DS225+ continues to use the Intel Celeron J4125, a 4-core, 4-thread processor first launched in late 2019. While it still performs adequately for DSM tasks, light media streaming, and small office workloads, it is now well behind newer processor architectures in terms of efficiency, instruction set support, and overall responsiveness.

Competing NAS units released in 2024 and 2025 have moved on to Intel N-series, Jasper Lake, or even embedded AMD processors, many of which offer better performance-per-watt, additional cores, and support for modern instruction sets such as AVX2 and higher memory bandwidth. In contrast, the J4125’s dated 14nm Gemini Lake Refresh architecture lacks modern features and could begin to show its age sooner, especially under multitasking or when running additional DSM packages concurrently.

Although the DS225+ is not intended for heavy virtualized workloads or media encoding, the use of such an older CPU architecture restricts its growth potential. During testing, even modest activity such as Surveillance Station recording or Synology Drive sync tasks caused the CPU to reach 60–70% utilization, leaving little room for additional services. Docker and Virtual Machine Manager are supported, but their use is constrained by both CPU headroom and the device’s limited memory ceiling. For users expecting to scale their usage over the next 3–5 years, the DS225+ may struggle to keep pace as DSM continues to evolve and introduce more background services, analytics, and real-time processing demands.

Integrated Graphics for Light Transcoding and Multimedia Tasks

A notable advantage of the DS225+ is its use of the Intel Celeron J4125, a quad-core x86 processor that includes integrated Intel UHD 600 graphics. While this is not a new CPU, the presence of onboard graphics enables hardware-accelerated video decoding and transcoding, a feature that’s become less common in newer NAS systems using ARM-based or non-iGPU x86 processors. For users planning to run Plex or Jellyfin, this hardware acceleration allows the DS225+ to handle light 1080p transcoding tasks—useful when streaming to devices with limited codec support or over constrained network connections.

This capability is especially important for homes or small offices that want centralized media storage without relying on local playback compatibility. During testing, the DS225+ performed adequately when transcoding one or two 1080p streams simultaneously, especially when the source files used H.264 or H.265 formats compatible with the GPU.

Synology’s native apps like Surveillance Station and Synology Photos also benefit from integrated graphics, improving responsiveness during thumbnail generation and background indexing of photos and videos. While not intended for intensive media workflows, the DS225+ offers enough GPU performance for common multimedia use cases, making it more versatile than similarly priced NAS units that lack any form of video acceleration.

Limited Memory and Restrictive Upgrade Policy

The DS225+ ships with just 2GB of DDR4 memory, which is soldered directly to the motherboard, limiting flexibility from the outset. While it does feature a single accessible SODIMM slot to expand the total memory to 6GB (2GB onboard + 4GB additional), Synology officially supports only their own branded 4GB memory module. Using non-Synology memory will either trigger DSM warnings or void technical support eligibility. This restrictive policy contrasts with other NAS vendors that support industry-standard memory upgrades more openly. In practical terms, the 6GB ceiling is already considered low for 2025, especially as DSM continues to expand its service ecosystem and memory-hungry packages like Photos, Drive, and Surveillance Station become more prevalent.

Real-world testing shows that even at idle with no user-installed applications, DSM often consumes 28–38% of available memory due to intelligent caching. Once additional services are installed—such as indexing, media streaming, or light virtual machines—the system can begin to feel constrained, leading to slower response times or increased reliance on swap memory. For example, enabling facial recognition in Synology Photos or running simultaneous Docker containers may quickly push the system beyond its comfortable operational range. This limitation makes the DS225+ poorly suited for users who want to experiment with virtualization, host large collaborative environments, or ensure headroom for future DSM features. Even for modest multi-user environments, the soldered memory and limited upgrade capacity represent a clear technical bottleneck.

Dual LAN Ports with 2.5GbE Support for Faster Transfers

The DS225+ is equipped with two Ethernet ports—one standard 1GbE and one 2.5GbE—giving users flexibility in how they connect and scale their network performance. This is a meaningful improvement over entry-level NAS models that only offer single Gigabit connectivity, especially as more consumer routers and switches begin to support multi-gigabit speeds. When paired with a compatible switch or direct 2.5GbE connection, the DS225+ can achieve transfer speeds up to 280–290MB/s under optimal conditions, significantly reducing the time needed for backups, media streaming, or large file transfers over LAN. For those sticking to 1GbE setups, the second port still provides redundancy or the option to separate network traffic between general access and administrative tasks.

Although the DS225+ does not support link aggregation or PCIe expansion, having dual LAN ports allows for some segmentation and future-proofing in small network environments. Users can reserve the faster 2.5GbE interface for high-priority devices such as a workstation or editing PC, while the 1GbE port can be used for background syncing, IP camera feeds, or system management. The inclusion of 2.5GbE is also relevant in home lab and prosumer scenarios, where higher-speed NAS-to-NAS replication or remote backup over multi-GbE connections is becoming more common. While the benefit is conditional on the rest of the network infrastructure supporting these speeds, it’s still an advantage that many previous 2-bay NAS models from this brand do not provide.

Limited I/O Expansion and Slower USB Connectivity

While the DS225+ includes the essentials for a basic NAS setup, its external connectivity is minimal, offering just two USB 3.2 Gen 1 ports, each limited to 5Gbps. This is notably behind the current standard of USB 3.2 Gen 2, which offers 10Gbps, and well below newer competitors that feature USB-C, eSATA, or PCIe slots for future expansion.

The lack of a front-mounted USB port or SD card reader also reduces convenience for users who regularly transfer media from cameras or external drives. In scenarios involving backup rotation, media ingestion, or hot-swapping data from multiple USB devices, users may find themselves manually unplugging and swapping cables due to the low number and placement of ports.

This limitation becomes more pronounced as the DS225+ cannot be expanded via PCIe, ruling out the addition of 10GbE networking, additional NVMe cache, or external SAS enclosures. Even Synology’s own expansion units are unsupported on this model, meaning what you see is essentially what you’re locked into for the lifespan of the system. While the DS225+ works well within its default role, users requiring scalable connectivity for workflows like multi-tiered backup, external archives, or direct media workstations will likely find it too constrained. The inability to expand I/O makes it harder to adapt the device as your setup grows or changes, placing it at a disadvantage in a market where even entry-level NAS units are becoming more modular.

Compact Design with Full DSM Access and RAID Flexibility

Despite its small physical footprint, the DS225+ delivers the full functionality of Synology’s DSM ecosystem, enabling users to configure advanced storage, backup, and collaboration features without needing a larger or more expensive unit. Measuring just 165 mm x 108 mm x 232.2 mm and weighing 1.3 kg, the DS225+ fits easily on a shelf, under a desk, or alongside other AV equipment. This makes it especially appealing to users with limited space or those looking to maintain a minimal setup. The 2-bay form factor supports 3.5″ SATA HDDs or 2.5″ SSDs, and users can configure their storage using Basic, JBOD, RAID 0, RAID 1, or Synology Hybrid RAID (SHR) depending on redundancy and capacity needs.

The benefit here is that while the DS225+ lacks the expansion features of higher-end NAS units, it doesn’t compromise on software or configurability. DSM allows for volume expansion with larger drives, RAID migration from Basic to RAID 1, and SSD TRIM support for improving SSD longevity. Users can also benefit from Btrfs snapshots and file versioning, even on this compact system.

This flexibility allows individuals to start with a single drive and expand or rebuild as storage needs increase. The ability to pair this with external drives via USB 3.2 for backups or offloading archived content extends its functionality further. For users who want the core NAS experience without the complexity or physical scale of larger models, the DS225+ is a strong, space-efficient option.

Unclear Upgrade Path Amid Synology’s Strategic Shift

The DS225+ sits within a transitional period for Synology, during which the company has increasingly signaled a shift toward pre-populated, locked-down platforms such as the BeeStation and BeeStation Plus series. These newer lines are aimed at users seeking simplicity and cloud-like convenience, but they also reflect Synology’s broader move toward closed ecosystems with tighter control over hardware and software integration. As these preconfigured models begin to replace traditional bare-metal Plus series NAS options in Synology’s lineup, it’s unclear how much longer models like the DS225+ will remain actively supported or prioritized in DSM development.

This creates uncertainty for prospective buyers who want a long-term investment. While Synology’s current support lifecycle is generally strong, the tighter coupling between software and specific hardware could eventually result in DSM updates being optimized for newer, more restrictive platforms. For example, users of the DS225+ may find that future DSM features—such as enhanced AI functions or hybrid cloud integrations—are limited or unsupported due to the older CPU or reduced memory ceiling.

Additionally, if the company continues to prioritize its locked-drive strategy and proprietary accessories, even firmware-level changes could make legacy systems like the DS225+ feel increasingly boxed in. This isn’t an immediate concern, but for users thinking 3–5 years ahead, the direction of Synology’s portfolio suggests the DS225+ may not age as gracefully as its predecessors once did.

Synology DS225+ NAS Review – Verdict and Conclusion

The Synology DS225+ delivers a polished and well-integrated NAS experience that caters to home users and small teams looking for dependable data storage, backups, and light multimedia handling. Its compact form factor, efficient thermal and acoustic design, and access to the full DSM 7.2 ecosystem make it a compelling choice for those who prioritize low noise, low power use, and a robust software suite. The inclusion of 2.5GbE networking, integrated graphics for basic Plex or Jellyfin transcoding, and support for Btrfs, SHR, and snapshot replication ensure that it remains practical for a wide range of core NAS tasks. It’s a system that “just works,” and for many users, that is enough to justify its place on their shortlist.

However, the DS225+ is increasingly defined by its limitations as much as its strengths. The use of an aging processor, restricted memory expansion, limited I/O, and locked-down drive compatibility significantly reduce its appeal for users who expect flexibility, performance headroom, or long-term scalability. When positioned against similarly priced or even cheaper NAS solutions from competing brands—many of which offer newer CPUs, broader third-party drive support, and better external connectivity—the DS225+ risks feeling outdated straight out of the box. Synology’s evolving product strategy also casts doubt on the long-term direction for devices like this. For users who are already committed to the Synology ecosystem or need something simple and quiet for basic NAS duties, the DS225+ can still be a solid purchase. For those looking for open-ended expandability or stronger hardware per dollar, however, it’s worth comparing alternatives or waiting to see how Synology’s next generation unfolds.

Synology DS1525+ NAS Review – A Solid Release, with bizarre compatibility rules

The Synology DS1525+ is the latest entry in the company’s long-running 5-bay Plus series, designed to deliver a flexible and reliable storage solution for small businesses, creative professionals, and advanced home users who require more capacity and functionality than entry-level models but do not need a full enterprise rackmount system. Retaining the familiar compact desktop chassis of its predecessor, the DS1522+, the DS1525+ supports up to 15 drives with two DX525 expansion units and integrates two M.2 NVMe slots for SSD caching or storage pools, catering to workloads that demand higher IOPS and tiered performance. Notably, it moves away from the Ryzen R1600 CPU found in the DS1522+, opting instead for the quad-core AMD Ryzen V1500B, a server-oriented processor that prioritizes file processing and ECC memory support over integrated graphics and media transcoding. This change aligns the system with Synology’s broader SMB product strategy, which emphasizes data integrity and predictable performance under multi-user access rather than consumer-oriented multimedia features.

The DS1525+ also introduces dual 2.5GbE ports, replacing the DS1522+’s four 1GbE ports, and retains a PCIe Gen3 ×2 slot for optional 10GbE network upgrades. These hardware refinements are paired with Synology’s DSM software platform, which continues to offer one of the most comprehensive and secure NAS operating environments on the market. However, as highlighted in testing and the accompanying video review, these benefits are tempered by Synology’s increasingly restrictive hardware validation policies, which limit drive and SSD compatibility and impose artificial constraints on expandability. This review examines the DS1525+ from multiple angles, including design, internal hardware, connectivity, software functionality, and overall value, to help prospective buyers determine whether its trade-offs and strengths align with their needs.

Synology DS1525+ NAS Review – Design and Storage

The DS1525+ continues Synology’s established design language, using a compact desktop enclosure measuring 166 × 230 × 223 mm and weighing just under 2.7 kg. The chassis is predominantly plastic on the exterior, with a metal internal frame to support the drive bays and improve rigidity. Although it retains the same overall appearance as the DS1522+, the DS1525+ benefits from thoughtful airflow improvements that enhance thermal performance under sustained workloads. Ventilation is provided by dual 92 mm rear-mounted fans, complemented by side and base vents to maintain consistent internal temperatures even with all five bays populated and two NVMe SSDs installed. The toolless 3.5” drive trays allow quick installation of SATA HDDs without screws, while optional brackets support 2.5” SATA SSDs if required. As noted during testing, the physical build remains sturdy and understated, making it a good fit for office and studio environments where noise and visual distraction are concerns.

In terms of storage flexibility, the DS1525+ supports five native drive bays, each hot-swappable, and accepts a mix of 3.5” SATA HDDs and 2.5” SATA SSDs. The bays are managed by Synology’s DSM software and support all common RAID configurations, including SHR, RAID 5, 6, and 10, enabling users to optimize for capacity, redundancy, or performance depending on their workload. The system can also scale up to 15 drives using two DX525 expansion units, connected via dedicated USB Type-C expansion ports on the rear. Although the move from eSATA to USB-C modernizes the connection standard, it does not significantly increase bandwidth, as it remains limited to approximately 5 Gbps per link, which can become a bottleneck if the expansion units are fully populated with high-speed drives. Despite this, the expandability remains useful for businesses that anticipate growing data storage needs over time, allowing gradual investment rather than a large upfront commitment.

A key design inclusion is the two M.2 2280 NVMe slots located on the underside of the chassis. These slots can be configured as read/write cache for improved random I/O performance or, with Synology’s verified SSDs, as dedicated storage pools. In testing, the NVMe slots were confirmed to operate at PCIe Gen3 ×4 per slot, providing ample bandwidth for most NAS-grade SSDs. However, as pointed out in the video review, the available Synology NVMe SSDs are endurance-oriented and limited in write speed, which may undercut the full potential of these slots for high-throughput storage pools.

The slots also remain restricted by Synology’s SSD validation policy, which prevents the use of competing brands and forces users to choose from Synology’s own range of NVMe drives, which are often more expensive and limited in capacity. Nonetheless, the M.2 slots provide additional flexibility for workloads that benefit from caching or tiered storage setups, particularly in virtualized or database-heavy environments. Another important design consideration is the thermal and acoustic behavior of the DS1525+ when fully populated and under sustained load.

During extended testing with five 7,200 RPM Synology HAT5300 HDDs and two NVMe SSDs, surface temperatures remained within acceptable ranges, averaging 38–43°C around the chassis and 65–70°C on the NVMe drives. The rear fans were able to maintain stable temperatures across the system even with high drive activity, and they support multiple fan profiles (Quiet, Cool, Full-Speed) for users to balance noise and cooling performance. The plastic chassis construction helps keep overall noise levels lower than metal-bodied alternatives, with measured idle noise between 36–39 dBA and peak noise under heavy load reaching around 52–55 dBA when using high-RPM drives. While not silent, it is unlikely to be disruptive in most office or home environments, especially when placed out of direct proximity to users.

Lastly, the DS1525+’s storage features are tightly integrated with Synology’s DSM platform, which supports a maximum single volume size of up to 108 TB (or 200 TB with sufficient memory). RAID migrations, volume expansions, and global hot spares are supported across all common RAID types, making it easy to adjust storage configurations as needs change. For businesses, the ability to expand storage on demand, coupled with snapshot and replication tools in DSM, ensures data resiliency and flexible recovery options. However, the strict hardware validation policy remains a limitation; users migrating from older systems with non-Synology drives may encounter warnings, inability to expand arrays, or even outright initialization failures with unsupported drives. This policy makes it essential to plan storage purchases carefully and verify compatibility prior to deployment.

Synology DS1525+ NAS Review – Internal Hardware

At the heart of the DS1525+ is the AMD Ryzen V1500B processor, a quad-core, eight-thread 64-bit CPU running at 2.2 GHz. This server-class embedded chip is designed primarily for file processing and multi-threaded workload stability, and its inclusion aligns with Synology’s focus on predictable performance and ECC memory support over multimedia capabilities. Unlike the Ryzen R1600 found in the earlier DS1522+, which offers higher clock speeds and integrated graphics, the V1500B omits hardware media encoding and transcoding support entirely, reflecting Synology’s deliberate pivot toward business-oriented file operations rather than consumer-grade media streaming.

The processor is soldered to the mainboard and not user-replaceable, but it provides sufficient compute power for services like Btrfs snapshots, high-volume SMB/NFS file serving, virtualization with up to eight recommended VM instances, and running multiple DSM applications simultaneously. Its support for ECC memory is particularly valuable in critical environments where data integrity is paramount, reducing the risk of corruption during power events or high load.

The system is equipped with 8 GB of DDR4 ECC SODIMM memory as standard, installed as a single 8 GB module. The motherboard provides two SODIMM slots, supporting up to 32 GB of total memory using 16 GB modules in a dual-channel configuration. This memory ceiling is adequate for typical SMB workloads, virtualization, and even moderate database applications, though users with heavier VM demands or larger hybrid cloud deployments may want to upgrade early. Synology strongly recommends using only validated Synology memory modules, as DSM will display warnings if unvalidated modules are detected, and technical support may be limited. During testing, the standard 8 GB configuration was sufficient for running DSM with multiple file shares, virtual machines, snapshot tasks, and background indexing processes without hitting memory bottlenecks. The memory can be easily accessed and upgraded by removing the side panel of the chassis, which is designed for straightforward maintenance.

Thermally, the DS1525+ maintains internal component stability even under full load. The processor is passively cooled, relying on the dual rear 92 mm fans for airflow across the entire system. Temperature readings during stress tests remained within specification, though the V1500B’s higher TDP compared to Intel Atom or Celeron CPUs results in slightly elevated baseline power consumption. The internal layout remains organized and clean, with the M.2 slots located on the underside of the chassis, separate from the mainboard and drive bays. This prevents localized hotspots and allows the fans to maintain airflow across all critical components, including memory and storage. Users should note that while the PCIe Gen3 interface supports expansion cards, the available slot is limited to ×2 link width, reflecting the moderate bandwidth needs of most NAS workloads but potentially constraining advanced 10GbE or multi-SSD configurations. The overall hardware architecture reflects a deliberate balance between cost efficiency, reliability, and the target workload profiles Synology intends for this model.

Synology DS1525+ NAS Review – Ports and Connections

The DS1525+ offers a streamlined set of connectivity options that aim to balance modern bandwidth requirements with compatibility and expandability. On the rear panel, the system features two RJ-45 2.5GbE network ports that replace the four 1GbE ports found on the DS1522+. These ports support link aggregation, failover, and SMB Multichannel for improved throughput and redundancy, but users will need a compatible 2.5GbE or multigigabit switch to fully realize their potential.

For users requiring more network bandwidth, Synology provides a PCIe Gen3 ×2 expansion slot that can accommodate an optional 10GbE NIC, allowing the system to scale up to much higher transfer rates when used in demanding environments such as large media libraries or high-concurrency file sharing. This combination of onboard 2.5GbE and optional 10GbE caters to a wide range of deployment scenarios, though the move from four ports to two may disappoint users who previously relied on the additional ports for VLAN separation or increased failover granularity.

In addition to networking, the DS1525+ includes two USB 3.2 Gen 1 Type-A ports, positioned on the rear, which support basic external storage and UPS connections. Unlike earlier models that offered limited support for USB accessories, the DS1525+’s USB implementation is largely relegated to these basic functions, and it does not support more advanced use cases like external GPUs or high-speed data ingest beyond the capabilities of USB 3.2 Gen 1. The USB ports are adequate for attaching backup drives or monitoring UPS status but are otherwise limited in functionality. Adjacent to the USB ports are two USB Type-C expansion ports that allow connection of up to two DX525 expansion units. While the move to Type-C modernizes the connector form factor, these expansion ports are still based on a SATA-equivalent bandwidth of roughly 6 Gbps per link, limiting their aggregate performance potential. Nonetheless, they enable storage scalability from five to 15 bays, maintaining a clear upgrade path without requiring a complete system replacement.

Physically, all ports are located on the rear panel, keeping the front of the chassis clean and accessible for drive access. The PCIe slot is located internally, and installing an expansion card requires removing the top panel. Users who need the optional 10GbE NIC should plan for this additional step during setup. Power input is handled through an internal 120W AC adapter, eliminating the need for an external brick and contributing to the system’s tidy cabling.

The system also supports Wake-on-LAN and power recovery, allowing administrators to automate power cycles and recover from outages remotely. The inclusion of two 2.5GbE ports reflects Synology’s incremental approach to adopting higher-speed Ethernet standards while maintaining affordability, but it also highlights the relatively modest ambitions of this generation when compared to competitive NAS units that have already adopted four-port 2.5GbE or standard 10GbE onboard configurations.

Synology DS1525+ NAS Review – Speed, Noise and Power Consumption Tests

The DS1525+ demonstrates controlled acoustic performance that is in line with its intended use in office or home environments. The dual 92 mm rear fans operate in three selectable profiles — Quiet, Cool, and Full-Speed — allowing users to adjust the balance between noise and cooling efficiency. During testing with five Synology HAT5300 7,200 RPM drives and two NVMe SSDs installed, idle noise levels were measured at approximately 36–39 dBA in Quiet mode, which is noticeable but unlikely to disturb most users. Under moderate load in Cool mode, noise levels increased slightly to around 37–40 dBA, while Full-Speed mode produced more airflow and reached approximately 43–45 dBA with minimal vibration. Peak noise occurred when the drives were under heavy access and the fans at maximum speed, reaching 52–55 dBA. As noted in the video review, at that point the drive mechanics themselves were more audible than the fans, especially when using high-RPM or larger capacity HDDs. Overall, the system remains suitable for placement in proximity to users as long as larger enterprise-grade drives are avoided.

In terms of power consumption, the DS1525+ is modestly more efficient than earlier generations, though still higher than lower-power Celeron-based alternatives due to the Ryzen V1500B’s higher baseline TDP. In the lowest idle state with no drives installed, the system consumed approximately 16.7–16.8 watts, which can be further reduced through DSM’s scheduled hibernation features. With five 4TB 7,200 RPM drives installed and idle, power draw increased to around 41–42 watts. During active workloads with all drives accessed simultaneously and a 10GbE NIC installed, power consumption peaked at roughly 60–68 watts, which is reasonable given the system’s capacity and workload. When tested using only the SSD storage pool over 10GbE, power draw settled between 53–58 watts, reflecting the efficiency of the NVMe SSDs but also the fact that the Ryzen CPU remains engaged during high-throughput operations. These figures highlight that while the DS1525+ is not among the most power-frugal NAS options, it remains within acceptable limits for its class.

Performance testing covered several storage configurations and network scenarios to evaluate throughput and responsiveness. Using five Synology HAT5300 drives in SHR and a Synology E10G22-T1-Mini NIC installed for 10GbE connectivity, sequential read speeds reached 900–950 MB/s, with write speeds peaking around 800–850 MB/s. This demonstrates that the system can effectively saturate a 10GbE link under optimal conditions with HDD-based arrays. Using only the two onboard 2.5GbE ports with link aggregation, the system achieved approximately 550–580 MB/s combined, which is sufficient for many SMB workloads but falls short of single 10GbE capabilities. NVMe performance was limited by Synology’s validated SSDs, which prioritize endurance over speed, reaching maximum write speeds around 750 MB/s and read speeds closer to 1,000 MB/s in a RAID 0 pool. As noted in testing, higher-performing third-party SSDs are not supported due to validation restrictions, which prevents the system from fully exploiting the NVMe slots’ Gen3 ×4 bandwidth potential.

For real-world mixed workloads, the DS1525+ proved capable of handling simultaneous file sharing, virtual machine hosting, and snapshot operations without significant degradation. Virtualization workloads supported up to eight recommended VM instances, and Surveillance Station operated within specification at up to 40 1080p cameras, though sustained workloads at maximum capacity may benefit from additional memory. File transfers over SMB maintained consistent throughput even under multiple concurrent sessions, and Btrfs snapshot and replication tasks completed within expected timeframes for the test array. The system’s stability and predictability align well with business-focused deployment scenarios, provided users adhere to the validated hardware list and plan network infrastructure accordingly. The key limitations in performance stem not from the hardware itself but from the imposed compatibility restrictions, which may prevent users from selecting higher-performing drives or SSDs.

Synology DS1525+ NAS Review – DSM Software

The DS1525+ runs Synology’s DiskStation Manager (DSM) operating system, which remains a cornerstone of its appeal. DSM combines an intuitive web-based interface with a rich suite of business, backup, collaboration, and security applications that are deeply integrated into the hardware. The operating system leverages the DS1525+’s hardware capabilities fully, supporting Btrfs as the default file system for internal volumes, providing snapshot-based recovery, advanced quota management, and replication options. In this model, DSM supports up to 32 internal volumes, 108 TB per volume (expandable to 200 TB with 32 GB of memory), and all common RAID configurations including SHR for flexible redundancy. File services are comprehensive, with SMB, AFP, NFS, FTP, Rsync, and WebDAV all included, as well as support for Active Directory, LDAP, and Kerberos authentication. The user and group management features allow up to 1,024 user accounts and 256 groups, making it suitable for departmental and SMB environments.

DSM’s package ecosystem enables the DS1525+ to function as more than just a file server. The system supports core Synology applications such as Active Backup for Business, which allows centralized backup of PCs, servers, and cloud services, and Synology Drive, which offers private cloud-style file sharing with file versioning and team collaboration. Hyper Backup facilitates multi-version backups to local or remote destinations, while Surveillance Station turns the NAS into a capable NVR, supporting up to 40 cameras at 1080p. Virtualization workloads are handled through Virtual Machine Manager, which supports up to eight recommended VM instances and integrates with VMware, Windows Server, and Citrix environments. The DS1525+ also supports Snapshot Replication, Hybrid Share for hybrid cloud workflows, and Synology Office and Chat for internal collaboration. The ecosystem continues to prioritize stability, security, and ease of management, which explains its popularity even in the face of growing hardware restrictions.

That said, DSM’s strength also highlights the ongoing tension between software capability and Synology’s restrictive hardware validation policies. The DS1525+ enforces validated drive and SSD lists for full functionality of features like RAID recovery, hot spares, and SSD storage pools. While DSM continues to outperform many competitors in usability and features, these artificial restrictions reduce hardware choice and increase costs. Prospective users should review Synology’s compatibility list before deploying third-party drives, especially if migrating from older systems. For those willing to adhere to Synology’s ecosystem, DSM delivers a mature, reliable platform that simplifies even complex workflows, while maintaining strong security practices and a steady cadence of updates.

Synology DS1525+ NAS Review – Verdict and Conclusion

The Synology DS1525+ is a capable and well-built NAS that continues the company’s focus on dependable performance, solid build quality, and integration with the robust DSM software ecosystem.

The inclusion of a server-grade Ryzen V1500B CPU and ECC memory support ensures predictable performance for file serving, virtualization, and surveillance workloads, while the dual M.2 slots and PCIe expansion keep it competitive in terms of flexibility. DSM remains a standout feature, providing an excellent range of tools for backup, collaboration, and hybrid cloud deployments that can save significant time and administrative effort in day-to-day use. From a hardware standpoint, it represents a moderate but clear improvement over the DS1522+ in terms of network bandwidth and workload readiness, even if some areas, like PCIe bandwidth and USB functionality, have seen little or no change.

However, the DS1525+ also reflects several limitations inherent in Synology’s current approach. The switch from four 1GbE ports to two 2.5GbE ports sacrifices some port redundancy and may require infrastructure upgrades to fully benefit. The reliance on validated Synology drives and SSDs, while arguably aimed at improving stability and support, adds cost and restricts flexibility, which can frustrate users migrating from existing hardware ecosystems. In performance terms, while the DS1525+ can saturate a 10GbE link under the right conditions, the full potential of its NVMe slots and PCIe expansion is hampered by both validation policies and hardware link width. Ultimately, this NAS is best suited for those already invested in Synology’s ecosystem or those who value software integration and ease of use over hardware openness. For buyers who prioritize predictability, software maturity, and a controlled experience, the DS1525+ delivers on its promises.

Review of the Synology DS1825+ NAS – Locked In?

The Synology DS1825+ is the latest 8-bay desktop NAS in the company’s established Plus series, positioned as the direct successor to the DS1821+ that launched in late 2020. After a considerable gap of nearly four years, expectations were high for significant improvements in hardware and features to match the evolving needs of small businesses, creative professionals, and advanced home users. Synology has chosen to retain the same AMD Ryzen V1500B processor, a quad-core 2.2 GHz CPU, while doubling the base memory to 8 GB ECC and upgrading the network interfaces to dual 2.5GbE. Notably, the DS1825+ also introduces tighter drive and SSD compatibility controls, supporting only Synology-validated HDDs and NVMe SSDs for storage pools. These decisions have sparked debate within the NAS community over whether the incremental updates and compatibility restrictions justify the increased price point. In this review, we examine how the DS1825+ performs in design, expandability, power efficiency, and software integration, and evaluate its suitability as a flexible yet reliable NAS solution in 2025.

Synology DS1825+ NAS Review – Quick Conclusion

The Synology DS1825+ is a solid but measured update to the company’s long-running 8-bay Plus series, combining a proven and durable chassis design, dependable performance, and the full-featured DSM software ecosystem with only modest hardware enhancements over its predecessor. The system maintains the robust all-metal build quality, excellent serviceability, quiet dual-fan cooling, and eight hot-swappable drive bays, expandable to 18 total with DX525 units for future growth. Notable upgrades include doubling the default memory to 8 GB ECC, scalable up to 32 GB for virtualization and heavy workloads, and replacing the DS1821+’s four 1GbE ports with two faster 2.5GbE ports that support link aggregation, failover, and SMB multichannel to better utilize modern networks. Internally, the Ryzen V1500B processor continues to deliver stable and consistent performance across tasks like file serving, virtual machines, snapshots, and surveillance, but it clearly lags behind newer processors in efficiency, PCIe bandwidth, and GPU-accelerated media handling, limiting its appeal for use cases like Plex transcoding or advanced PCIe storage.

DSM remains the system’s strongest attribute, offering a comprehensive suite of business-grade features including Btrfs snapshots, hybrid cloud replication, Docker, SAN Manager, and support for up to eight virtual machines and dozens of IP cameras, all managed through a user-friendly interface. However, the increasingly strict hardware validation policy for HDDs and SSDs means DSM features such as RAID recovery, hot spares, and SSD storage pools require Synology-verified components, which can drive up costs and limit flexibility compared to earlier models. In our testing, the DS1825+ delivered reliable performance, predictable noise and power levels, and excellent expandability, but it trades openness and cutting-edge hardware for stability, integration, and controlled user experience. It is best suited for buyers already invested in the Synology ecosystem who prioritize seamless software, long-term support, and predictable operation over maximum hardware choice or price optimization. But like many Synology solutions released in 2025, this is a product marred by their increasingly aggressive media compatibility policy and, in months to come, if/when further alternative drives appear on the support lists – many of us will wonder what the point of it all was. This is a solid solution, that is tainted by a significant and artifical shortcoming created by the brand themselves. I still recommend it, but be aware of it’s qwerks.

Synology DS1825+ NAS Review – Design & Storage

The DS1825+ continues Synology’s long-standing chassis design used across its larger desktop NAS models, retaining the familiar all-black metal and plastic enclosure. Measuring 166 mm high, 343 mm wide, and 243 mm deep, and weighing around 6 kg, it maintains the compact footprint expected of an 8-bay system while offering good internal airflow and accessibility. The front panel houses eight tool-less drive trays, each supporting either 3.5” SATA HDDs or 2.5” SATA SSDs, with hot-swapping supported on the main bays. Unlike the predecessor, this model enforces strict validation of drives, allowing only Synology-branded HAT5300 series HDDs and SAT5200/5210 SSDs, a significant limitation compared to earlier generations which were more permissive toward third-party drives. The front panel also features brightness-adjustable LEDs, a power button, and USB 3.2 ports for quick external access.

Internally, the DS1825+ provides two M.2 2280 NVMe SSD slots, designed primarily for SSD caching, but also supporting storage pools when used exclusively with Synology’s own NVMe SSDs. These slots use PCIe Gen 3 x4 links, which is adequate for caching and light storage workloads, though significantly behind what Gen 4-capable SSDs could theoretically offer. Importantly, the M.2 slots do not support hot-swap, and installing SSDs requires removing the chassis cover. The use of these NVMe slots for primary storage pools remains an appealing option for virtualized workloads or high-IOPS applications, albeit limited by the drive selection policy and the modest PCIe 3.0 bandwidth.

For users requiring greater capacity, the DS1825+ can be expanded up to a total of 18 drive bays by attaching up to two Synology DX525 expansion units via rear-mounted USB-C ports. This expandability enables support for larger storage pools as business needs grow, but it is worth noting that the expansion connection bandwidth is limited to USB 3.2 Gen 1 levels, which is equivalent to 5 Gbps, potentially creating a bottleneck if fully populating both expansion units with high-capacity drives. The backward-compatible design allows users of older DX517 units to repurpose them, though at a reduced performance ceiling. Unlike rackmount models, the DS1825+ does not support redundant power supplies or expansion over faster SAS connections.

One of the standout aspects of the DS1825+ remains its toolless drive trays, which include plastic clips for 3.5” drives and mounting holes for 2.5” SSDs. This makes maintenance and upgrades straightforward, and the internal dual 120 mm fans can also be replaced easily if needed. The chassis provides three fan modes—full-speed, cool, and quiet—allowing users to balance between thermal performance and noise levels. Overall, the physical construction remains solid and serviceable, benefiting from the company’s years of refinement in NAS hardware design.

The DS1825+ maintains its reputation for efficient use of space while improving storage scalability options over its older siblings. However, its strict drive compatibility requirements limit flexibility for those who previously mixed and matched drives based on cost or availability – which is a little bit of a dampener when you think about how appealing SHR (Synology htbrid RAID) is with those that gradually upgrade storage over the years in a single RAID pool. While the ability to expand to 18 bays and to leverage SSD caching or pools is welcome, users must carefully plan their deployment around Synology’s approved hardware list to avoid operational warnings or outright incompatibility.

Synology DS1825+ NAS Review – Internal Hardware

At the heart of the DS1825+ is the AMD Ryzen V1500B processor, a quad-core, eight-thread 64-bit CPU running at 2.2 GHz. This is the same embedded server-grade chip used in its predecessor, the DS1821+, and is designed for consistent, reliable file processing and multi-tasking in a NAS environment. The V1500B supports ECC memory and offers a modest power envelope compared to consumer-grade CPUs while delivering sufficient performance for most small business tasks, including light virtualization, high-volume file sharing, and running multiple DSM services simultaneously. Notably, the processor lacks integrated graphics, which means it does not support hardware-accelerated video transcoding—a limitation noted during testing and worth considering for users planning to run Plex or similar media servers. Despite its age and modest clock speed by 2025 standards, the V1500B remains a capable chip in terms of PCIe lane allocation and IOPS throughput for NAS workloads, striking a balance between power efficiency and server-oriented stability.

Memory in the DS1825+ is configured as 8 GB of DDR4 ECC SODIMM out of the box, doubling the 4 GB baseline offered on the DS1821+. The system uses standard SO-DIMM slots and offers two memory slots in total, supporting up to 32 GB (2 × 16 GB) if both slots are populated. During testing, the system correctly reported and utilized Synology-branded ECC memory, which the company mandates for full warranty and support compliance. While technically compatible with some third-party modules, users choosing non-Synology memory risk reduced support and the possibility of system warnings in DSM. The inclusion of ECC memory is crucial for ensuring data integrity, especially in RAID arrays and virtual machine workloads, where single-bit memory errors could otherwise lead to data corruption. In practice, 8 GB is adequate for smaller file-serving and backup scenarios, but users planning to run multiple virtual machines, intensive database applications, or very large volumes beyond 108 TB should strongly consider upgrading to the maximum supported memory to maintain performance under heavier loads.

The DS1825+ includes a single PCIe Gen3 x8 slot, operating at x4 link width, which provides flexibility for network upgrades and additional functionality. This slot supports Synology’s own PCIe expansion cards, including 10GbE NICs and M.2 NVMe SSD adapters for additional caching options. However, as noted during testing, some older or third-party PCIe cards that function on other Synology systems were not recognized by the DS1825+, suggesting firmware-level restrictions similar to the strict drive compatibility policies. This limits user choice somewhat and reinforces Synology’s preference for a controlled hardware ecosystem. The PCIe slot itself is easily accessible after removing the cover and is positioned above the mainboard in line with the rear ventilation path, ensuring adequate cooling for add-in cards even during prolonged operation. While the PCIe slot is a welcome inclusion for future-proofing, its limitations in both bandwidth (Gen3 ×4) and card support should be carefully weighed by users planning advanced configurations.

Synology DS1825+ NAS Review – Ports and Connections

On the back of the DS1825+, Synology has revised the network interface configuration to reflect more modern bandwidth expectations while keeping the overall I/O layout consistent with prior models. The system now features two 2.5GbE RJ-45 LAN ports, replacing the four 1GbE ports found on the DS1821+. This effectively doubles the available aggregate bandwidth compared to its predecessor when used with a compatible switch, while also supporting SMB Multichannel, link aggregation, failover, and load balancing through DSM’s network manager. During our testing, the 2.5GbE ports performed reliably and reached near-maximum throughput when paired with high-speed drives or SSD caching. However, the reduction from four ports to two has been met with mixed reactions, as it removes the option to segment traffic across more physical interfaces, which some users previously leveraged for separate VLANs or dedicated services.

Alongside its LAN ports, the DS1825+ includes three USB 3.2 Gen 1 Type-A ports, two located on the rear and one on the front panel. These ports support external hard drives, SSDs, UPS devices, and a limited number of compatible peripherals. For expansion, the system offers two USB Type-C ports on the rear for connecting DX525 expansion units, each adding five additional drive bays. While the shift to USB-C modernizes the physical connectors compared to the legacy eSATA ports used previously, it is important to note that the underlying bandwidth is still equivalent to USB 3.2 Gen 1 (5 Gbps). This limitation may impact performance if fully populating multiple expansion bays, particularly if configured with high-capacity 7,200 RPM HDDs or SSDs. During our testing, expansion connectivity was stable but not as fast as many users might assume given the Type-C connectors. No additional USB-C functionality for general peripherals is supported—these ports are strictly reserved for expansion chassis.

The system’s PCIe Gen3 x8 slot complements the onboard I/O, providing a pathway for additional high-speed interfaces. Synology’s supported PCIe cards include 10GbE network adapters and additional NVMe SSD adapters, which can unlock greater bandwidth potential or dedicated SSD storage for high-performance applications. However, as discussed in the hardware section, card compatibility is limited to Synology-validated options, and some third-party cards that work in earlier models may not function here. This means users planning to scale beyond the included 2.5GbE must factor in the added cost of Synology’s cards. Physically, the slot and I/O arrangement remain clean and accessible, with sufficient spacing to avoid airflow obstructions, and the internal fans provide adequate cooling even under sustained high-speed transfers.

Synology DS1825+ NAS Review – Heat, Noise and Storage Performance Tests

The DS1825+ maintains the same overall acoustic profile as its predecessor, though some subtle differences emerge in testing due to changes in fan tuning and drive validation. Equipped with two 120 mm rear-mounted fans, the system allows users to select between Full-Speed, Cool, and Quiet modes through DSM. In our tests with eight Synology HAT5300 7,200 RPM drives, idle noise measured between 35–38 dBA in Quiet mode, rising to 39–41 dBA under moderate load in Cool mode. At maximum fan speed, noise levels reached 44–46 dBA, which is audible in office environments but not disruptive. During intensive drive access, with fans set to Auto, the system balanced cooling with acoustics, averaging 48–50 dBA. It’s worth noting that drive selection significantly affects perceived noise—higher capacity drives or older models with louder bearings can exceed these figures. The fans remain easy to replace and are effective at maintaining stable internal temperatures even during sustained RAID rebuilds or virtualization workloads, underscoring Synology’s mature thermal management design.

In terms of power consumption, the DS1825+ exhibits predictable behavior for a system of this size and hardware configuration. With no drives installed, idle power draw measured around 21–22 watts with one LAN port active. Fully populated with eight HAT5300 HDDs and left idle with fans on Auto, consumption increased to a baseline of 57–62 watts. This rises further during drive-intensive operations, with power usage determined primarily by the number and type of drives installed—HDDs can draw between 3–10 watts each depending on workload. The Ryzen V1500B is not an especially low-TDP processor, but its efficiency under file-serving workloads keeps total system power reasonable. DSM allows users to fine-tune power use further through features such as scheduled on/off, drive hibernation, and Wake-on-LAN, which proved reliable during testing. Compared to smaller NAS systems, the DS1825+ naturally consumes more power due to its larger drive count and internal fans, but remains efficient relative to comparable 8-bay business-class models.

Performance of the DS1825+ aligns closely with the DS1821+ it replaces, as the core CPU and architecture remain unchanged. In our testing with eight HAT5300 drives configured in RAID 6, sequential read speeds over the dual 2.5GbE ports easily saturated a single link, averaging 290–295 MB/s. When link aggregation was enabled, throughput peaked near 580 MB/s under optimal conditions, confirming the benefit of aggregated connections for large file transfers. When fitted with Synology NVMe SSDs in caching mode, random read and write latencies improved noticeably, particularly in multi-client scenarios or under virtualization workloads. Using NVMe SSDs as storage pools further improved responsiveness but was constrained by the PCIe Gen3 ×4 bandwidth ceiling and limited SSD model options.

For video editing or high-volume content serving, the DS1825+ still benefits from installing a 10GbE NIC, though buyers should factor in the added cost of both the card and compatible network equipment. CPU-intensive tasks like running multiple VMs or DSM apps simultaneously are handled adequately, though media transcoding remains unsupported due to the lack of an integrated GPU.

The system’s flexibility in RAID and storage configurations allows it to adapt to different usage patterns, but it’s clear from our tests that performance is gated more by Synology’s validation policies and hardware constraints than by raw capability. For example, attempts to use third-party SSDs for caching or pools resulted in warnings and reduced feature access, despite the hardware technically supporting them. Similarly, third-party 7,200 RPM NAS HDDs could not be initialized in DSM at all, forcing reliance on Synology’s own drives. This imposed restriction does not impact the system’s fundamental speed or reliability once properly configured but does affect cost and planning. Overall, the DS1825+ delivers solid, predictable performance for its class, but users expecting a generational leap over the DS1821+ may find the gains modest and mostly limited to network throughput and improved default memory.

Synology DS1825+ NAS Review – DSM

The DS1825+ runs Synology’s latest DiskStation Manager (DSM) operating system, providing a consistent and mature software experience across the company’s product line. DSM continues to be one of the strongest reasons to choose Synology, offering a polished browser-based interface, extensive administrative controls, and a large ecosystem of first-party and third-party applications. The DS1825+ ships with the full DSM suite enabled, supporting features like Snapshot Replication, Hyper Backup, Synology Drive, and Virtual Machine Manager out of the box. During testing, DSM performed reliably, with the hardware fully supporting even advanced features like Btrfs file system snapshots, multi-version backups, and iSCSI SAN services. Resource usage remained modest even with several concurrent services running, thanks to the Ryzen CPU and ECC memory ensuring stability and data integrity.

One of DSM’s strengths is its virtualization and containerization support, which the DS1825+ leverages effectively. With its quad-core CPU and up to 32 GB of memory, the system can host several virtual DSM instances or lightweight Linux and Windows VMs via Virtual Machine Manager. Our tests demonstrated support for up to eight recommended VM instances and full compatibility with VMware, Hyper-V, Citrix, and OpenStack environments. The system also handles Docker containers well, although its lack of integrated graphics limits its appeal as a media transcoding server. Surveillance Station also remains fully functional here, with support for up to 40 IP cameras at 1080p H.264 and licensing for two included channels, expandable with additional licenses. This makes the DS1825+ a viable choice for businesses looking to consolidate surveillance storage and general file services on a single platform.

Application support on the DS1825+ aligns with Synology’s broader Plus-series feature set, and DSM’s package center provides easy access to install and manage additional services. The system supports the full suite of collaborative tools such as Synology Office, Chat, MailPlus, and Calendar, with tested limits of around 100 simultaneous users for office productivity and chat workloads. Hybrid Share and C2 cloud integration extend functionality into hybrid environments, allowing users to leverage Synology’s own cloud for offsite replication or shared folders. Synology Drive provides private cloud file synchronization for up to 100 users and over a million hosted files, making the system suitable for medium-sized teams. While the strict hardware validation policies discussed earlier extend to SSDs and HDDs, they do not affect DSM’s software features, which remain fully unlocked and accessible regardless of drive choice.

Synology DS1825+ NAS Review – Verdict and Conclusion

The Synology DS1825+ is a competent evolution of the company’s long-running 8-bay Plus series, offering measured yet meaningful updates in key areas such as default memory, network bandwidth, and support for Synology’s mature DSM ecosystem. The system retains its robust all-metal chassis with a compact footprint, efficient dual-fan cooling, and easy-to-service drive trays and components. The addition of dual 2.5GbE networking, which supports link aggregation and SMB Multichannel, better aligns with current network environments, though it still requires compatible switches to fully realize its bandwidth potential. The upgrade to 8 GB ECC memory by default, scalable up to 32 GB, provides headroom for virtualization workloads and ensures data integrity during multi-threaded operations like iSCSI SANs and virtual machine hosting. In practice, the DS1825+ performed reliably across all tested DSM features, including Snapshot Replication, Hybrid Share, and Synology Drive, even under heavier RAID 6 configurations. Noise and power consumption stayed within the expected range for an 8-bay business-class NAS, and its expandability to 18 bays via DX525 units ensures the DS1825+ remains a viable option as storage needs grow over time. Taken together, it offers a dependable and familiar experience that continues to serve Synology’s target audience well.

However, the DS1825+ is equally defined by compromises that prospective buyers must consider carefully before purchase. Synology’s increasingly rigid compatibility policies for both HDDs and NVMe SSDs significantly reduce flexibility and raise costs, as users are now effectively required to source only Synology-validated drives to avoid warnings and to unlock certain DSM features like RAID recovery, hot spares, and SSD storage pools. The hardware platform itself, anchored by the now four-year-old Ryzen V1500B processor, has not evolved meaningfully, leaving it without GPU-based transcoding capabilities and limiting PCIe bandwidth to Gen3 ×4 for both add-in cards and NVMe slots. The replacement of the DS1821+’s four 1GbE ports with only two 2.5GbE ports arguably improves aggregate throughput but sacrifices the port density some environments depend on for VLANs or dedicated service segregation. As noted in our testing, PCIe card support also remains restricted to Synology’s own validated models, further constraining upgrade paths for networking or SSD configurations. For those deeply invested in Synology’s ecosystem and who value its software integration and long-term reliability over hardware flexibility, the DS1825+ remains a strong choice that delivers on stability and ease of use. For users prioritizing maximum hardware control, wider component compatibility, or newer processing capabilities, competing platforms with more open policies may better suit their needs. Ultimately, the DS1825+ continues Synology’s tradition of reliable and controlled NAS solutions, but with a narrower appeal than in previous generations.

Synology Hard Drives and SSD Comparison with Seagate/WD/Toshiba and More – Deal Breaker?

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

In response to growing user concern, we conducted a comparison of Synology’s drive lineup against the current offerings from Seagate, WD, and Kingston—analyzing each in terms of price per terabyte, real-world performance, durability specifications, and availability. Drawing from direct benchmarking, manufacturer datasheets, and controlled NAS testing environments, this article aims to answer a key question: is Synology’s branded media actually worth the premium? While some users may welcome the simplicity of a one-brand ecosystem, others are understandably wary of higher costs, limited SKU availability, and the potential long-term implications of vendor lock-in. Let’s break down what Synology drives really offer—and where they fall short—compared to the tried and tested alternatives on the market.

Synology Hard Drives and SSDs – What Drives Are There to Buy?

Synology’s storage media catalog is divided across value, prosumer, enterprise SATA, and SAS hard drives, alongside both SATA and NVMe SSDs. While these drives carry the Synology name and firmware, they are not designed or manufactured in-house. Instead, Synology rebrands OEM hardware from established vendors: Toshiba for the enterprise SATA and SAS drives, Seagate for the value-tier NAS HDDs, and Phison-based platforms for SSDs. The internal firmware is customized by Synology to integrate tightly with DSM, and in some cases, to restrict compatibility to only their branded drives within the latest 2025 NAS systems.

The naming scheme makes it easier to distinguish between drive classes:

• HAT for SATA NAS hard drives

• HAS for SAS enterprise drives

• SAT for SATA SSDs

• SNV for NVMe SSDs

This segmentation aims to help users align their hardware with expected durability (e.g. workload in TB/year), power loss protection, and RAID integration. However, it’s worth noting that several of these drives are virtually identical to third-party counterparts—particularly in the HAT3300 and HAT3310 lines, which closely mirror Seagate IronWolf models down to mechanical structure and spec. Despite this, third-party versions of those drives remain incompatible with key RAID features on the latest Synology systems unless they are officially “verified.”

	800GB	$299.99	$374.99

While Synology’s branding suggests ecosystem cohesion, it’s essential to recognize that their drive firmware is not engineered for general-purpose systems. These drives are optimized—and in some cases restricted—for Synology NAS environments. However, performance benchmarks show that Synology drives often perform equivalently or slightly below their third-party counterparts in synthetic and real-world tests. Moreover, price comparisons reveal a 5–15% markup on average in the value tier, and significantly higher deltas—often exceeding 30–40%—in the enterprise-class and SSD segments. Combined with regional supply inconsistencies and limited SKU availability, the value proposition of Synology-branded drives remains hotly debated, especially when identical hardware from Seagate or Toshiba can be purchased for less—if only the 2025 NAS series would support them natively.

Synology Hard Drives and SSDs vs Seagate, WD, etc – Price per TB and Value

When it comes to entry-level NAS hard drives, the price differences between Synology’s HAT3300 and HAT3310 series and their third-party equivalents—such as Seagate IronWolf and WD Red Plus—are generally modest. In most cases, the cost per terabyte (TB) stays within a 0% to 15% margin, with Synology’s versions sitting slightly higher. For casual or home users who just want a drive that “just works” out of the box and benefits from firmware-level integration with DSM, that small premium might feel justifiable.

But the story changes dramatically as we move into prosumer and enterprise territory. Drives like the Synology HAT5300 and HAS5300 series can cost 40%–50% more than Seagate IronWolf Pro, WD Red Pro, or Seagate Exos alternatives—despite sharing the same mechanical internals in many cases. These aren’t just marginal differences; when you’re building a multi-drive RAID array with 12TB or 16TB drives, that pricing gap quickly snowballs into hundreds or even thousands of dollars extra. And this is particularly frustrating when, for example, Synology’s 12TB HAT5300 (built on Toshiba hardware) costs nearly double what a comparable IronWolf Pro sells for, despite similar endurance ratings and warranty terms.

In short, while Synology’s drives are built on reputable platforms and do offer advantages like verified DSM integration and predictable firmware behavior, the value proposition becomes questionable—especially in higher capacities and enterprise deployments. For many users, especially SMBs and home power users deploying multi-drive setups, that extra 40–50% markup can be hard to justify. When the mechanical hardware is near-identical and the only major differentiator is firmware control, it’s no wonder many are pushing back against this pricing structure.)

Zoom in to see the results. IMPORTANT that you keep in mind that these SSDs and HDDs are different capacities and therefore direct comparison and correlation between their performance is not fair – I include these because I think it is important to compare the general gist of using Synology HDD media in a system and then alternatives, but measured with Synology’s in-system tools. Larger capacities mostly tend to yeald better results in any brand of drive (not a ‘do-or-die’ rule, but generally true).

Synology Hard Drives and SSDs vs Seagate, WD, etc – Performance

IMPORTANT – In the process of upscaling the test result images (as there is a lot crammed in, so I have included the slightly blurred ones here) but I and will replace these with upscaled versions as soon as possible.

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

Seagate Exos	12–24TB	285 MB/s	7200 RPM	550 TB/yr	2.5M hrs	Enterprise SAS

Performance parity continues with Synology’s SATA SSDs. The SAT5221 and SAT5210 series are very close in spec to Kingston’s DC600M drives, offering similar read/write speeds, IOPS performance, and endurance levels. The SAT5210 even pushes into ultra-DWPD territory, boasting up to 10,000 TBW and higher daily write thresholds, which is competitive in the enterprise space. If you need high write endurance and steady power loss protection, these drives tick the right boxes.

The gap, however, opens up in the NVMe tier. Synology’s SNV3400 and SNV3500 drives fall short compared to third-party NVMe SSDs like the WD Red SN700. While Synology focuses on endurance, PLP (power loss protection), and integration with DSM caching features, the performance ceiling on these drives is noticeably lower—both in terms of sequential throughput and IOPS. Capacities also top out at 800GB, while others offer 1TB and beyond with faster read/write performance. So if you’re after speed or larger NVMe caching pools, Synology’s current options may feel behind the curve.

SATA & NVMe SSDs – Synology vs Kingston

In short, Synology’s drives generally deliver solid, reliable performance that matches their third-party foundations—but the benefits of full DSM compatibility come with a trade-off. While the SATA range holds its ground, the NVMe lineup is due for an update if Synology wants to stay competitive against higher-capacity, higher-speed SSDs now widely available elsewhere. If performance is your main concern, particularly for NVMe caching or flash-heavy tasks, third-party options may be a better fit unless full integration is a must-have.

Synology Hard Drives and SSDs Guide – The Good and the Bad

In reviewing Synology’s lineup of hard drives and SSDs, it’s clear that the hardware itself is solid—built on trusted OEM foundations and tuned to work seamlessly within DSM environments. From a compatibility and reliability standpoint, these drives do offer advantages, particularly for users who want an integrated, no-hassle deployment. That said, these benefits come with notable trade-offs. In many cases, Synology’s drives are mechanically identical to models from Seagate, Toshiba, or Phison, yet priced significantly higher—especially in the enterprise and NVMe tiers. While some of that premium may be justified by firmware-level integration, PLP, or simplified support paths, the cost disparity is hard to ignore for experienced users already comfortable with third-party hardware.

Ultimately, the decision to adopt Synology-branded drives will depend on your priorities. If you’re building a system where out-of-the-box compatibility, long-term support, and unified ecosystem control are paramount, Synology’s media may be a safe bet—albeit at a higher packaged price. But if your focus is on maximizing performance per dollar, scaling capacity, or customizing your setup beyond Synology’s verified list, third-party alternatives remain the more flexible and cost-effective choice. Until Synology expands their verified media list and adjusts regional pricing or availability, many users will continue to see these drives not as a value-add, but as an imposed requirement.

The Synology DS925+ versus QNAP TS-464 – Buy NEW or Buy QNAP?

Every so often in the NAS market, a new model arrives that challenges not just its predecessors but also its closest competitors. With the 2025 release of the Synology DS925+, buyers now face an interesting dilemma: go with Synology’s latest compact powerhouse, or choose QNAP’s TS-464—a device that has already proven itself since its release in 2022/2023 and offers a wide array of features at a competitive price. The DS925+ brings notable upgrades to CPU architecture, system memory scalability, and integration within Synology’s tightly controlled ecosystem. Meanwhile, the TS-464 has spent years benefiting from firmware maturity, PCIe expandability, and a more open hardware approach that appeals to power users and tinkerers alike. But which device is ultimately the better buy in 2025? Should you embrace Synology’s ecosystem with its newer, high-performance release, or does QNAP’s more versatile and budget-friendly offering still hold strong in the face of newer competition? Let’s dive into the details to help you decide which NAS deserves your next investment.

Synology DS925+ vs QNAP TS-464 – Hardware Specifications

When placing the 2025 Synology DS925+ alongside the 2022/2023 QNAP TS-464, one might expect the newer model to clearly dominate in every area. But hardware comparisons in the NAS market are rarely so simple. While both units are aimed at tech-savvy home users and small businesses looking for reliable, always-on storage solutions, their approaches to hardware—and the user needs they prioritize—are noticeably different. The DS925+ emphasizes streamlined performance, reduced noise, and integration within Synology’s tightly managed ecosystem. The QNAP TS-464, meanwhile, leans into raw hardware flexibility, DIY expandability, and a more open feature set for power users. Below is a detailed hardware breakdown of both NAS devices, showing where each shines and where compromises were made.

The DS925+ delivers a refined hardware experience out of the box, with its newer AMD Embedded Ryzen V1500B 4 Core/ 8 thread processor, dual 2.5GbE ports for faster LAN connectivity, and modern I/O including USB-C. It features two M.2 NVMe slots (for cache only, unless you use the Synology SNV3400 drives from Synology), dual memory slots supporting up to 32GB of ECC DDR4 RAM, and a compact metal chassis designed for quiet, efficient operation. It also runs cooler and quieter than many of its rivals, making it an ideal fit for environments where noise levels matter—such as living rooms, home studios, or small offices. This makes the DS925+ a “plug-and-play” NAS with premium internal components and minimal need for user intervention.

By contrast, the QNAP TS-464 takes a more modular, expandable approach. Powered by the Intel Celeron N5105/N5095 CPU (a quad-core processor with integrated graphics, but only 4 threads), it offers HDMI 2.0 output, two M.2 PCIe Gen3 x1 slots (which can be used for either caching or storage pools), and a PCIe Gen3 x2 slot for optional 10GbE or more M.2s, USB expansion, or even GPU cards. QNAP also includes dual 2.5GbE ports, putting it on par with the DS925+ in terms of network speed, but it edges ahead in overall hardware adaptability. Want multimedia output via HDMI? QNAP has it. Want to add NVMe storage pools or real-time transcoding? QNAP supports that too. That said, the TS-464 is based on a slightly older CPU architecture, lacks ECC memory support, and typically generates more fan noise under load. Additionally, its OS and ecosystem are broader in scope but often require more manual setup. Ultimately, the DS925+ is purpose-built for those who prioritize a quiet, polished, and simplified experience with modern performance. The TS-464, on the other hand, remains an excellent choice for users who prefer control, multimedia support, and greater hardware flexibility. Choosing between them largely depends on whether you value Synology’s stability and turnkey design, or QNAP’s freedom and potential.

AMD V1500B vs Intel N5105 – CPU Specifications (Synology DS925+ vs QNAP TS-464)

In any NAS system, the processor plays a pivotal role in determining the scope of functionality—whether it’s managing multiple concurrent users, running virtual machines, powering AI-driven applications, or simply handling encrypted transfers and background tasks efficiently. The Synology DS925+ and the QNAP TS-464 take noticeably different approaches in this regard. The DS925+ features the AMD Ryzen Embedded V1500B, a server-grade SoC designed for sustained multi-threaded workloads. The TS-464, on the other hand, runs on the Intel Celeron N5105, a more consumer-oriented chip that prioritizes integrated multimedia support and power efficiency. While both CPUs are quad-core, their architecture, instruction set, and target use cases diverge sharply—affecting not only raw processing, but also the capabilities unlocked within DSM and QTS/QuTS, respectively.

In terms of raw specs, the V1500B offers 4 cores and 8 threads with a base clock of 2.2GHz and support for ECC memory—a key advantage for mission-critical environments. This CPU is built for multitasking and thrives in scenarios involving virtual machines, container services, and intensive file indexing or backup operations. As a result, the DS925+ supports up to 8 concurrent virtual machines, 8 virtual DSM instances, and higher thresholds for connected users across Synology apps. It is better suited to offices or power users who rely on services like Synology Office, Drive, or Surveillance Station running in tandem. The system handles up to 150 Synology Chat users, 80 Office users, and 80 Drive users, offering excellent multitasking performance with low overhead.

The QNAP TS-464’s Intel N5105 is a 10nm Jasper Lake processor, also quad-core but without hyper-threading and with a slightly lower base clock (2.0GHz). However, it includes integrated Intel UHD Graphics, giving it one key advantage the DS925+ lacks: hardware-accelerated video transcoding via QNAP’s own QuMagie, Video Station, and especially Plex Media Server with support for on-the-fly 1080p and 4K decoding when paired with proper client-side licensing. This makes the TS-464 ideal for multimedia-heavy environments. Beyond media, the N5105 powers QTS and QuTS hero with access to QNAP’s broader and often more modular ecosystem. This includes Hybrid Backup Sync (HBS 3) for unified backup and disaster recovery, QuDedup for deduplicated snapshot replication, QVR Elite and QVR Pro for professional-grade surveillance (supporting multiple IP camera licenses natively), and AI Core features like face recognition and event detection when paired with the QuMagie or QVR Human apps. The TS-464 also supports Virtualization Station, enabling users to run lightweight Linux or Windows VMs with direct passthrough access to USB or PCIe devices, and Container Station, which offers both Docker and LXC container compatibility with GPU passthrough for NPU-based AI inference workloads. Thanks to the included PCIe Gen 3 x2 slot, the system supports optional upgrades like 10GbE NICs, QM2 expansion cards (for M.2 SSD or additional 2.5GbE/10GbE ports), or even Wi-Fi 6 cards, something entirely absent in the DS925+. Additionally, QNAP allows direct output to an external display via HDMI 2.0, enabling standalone use of HD Station apps like Chrome, LibreOffice, Kodi, and even Linux desktop environments — a feature highly prized in HTPC and security NVR deployments. Users can leverage Linux Station to run full Ubuntu VMs locally, or install Ubuntu Core through the App Center for custom development or edge AI inference scenarios.

Taken together, the TS-464 may not support the same high virtual machine/user count as the DS925+, but it compensates with a broader set of integrated appliances catering to power users, home labs, edge AI, and media-heavy deployments. It’s a more “tinker-friendly” platform, favoring flexibility and breadth over centralized system control and vertical integration. If you need an appliance that works across entertainment, security, and hybrid cloud workflows, with room for add-on functionality via hardware or apps, the TS-464 is hard to beat for the price. That said, the Synology DS925+ ultimately offers greater headroom for enterprise workflows, heavier VM usage, and large-scale hybrid deployments. It sacrifices media transcoding and graphical acceleration, but gains a server-class CPU that ensures consistent performance under heavier load conditions. Meanwhile, the TS-464 excels in edge-case versatility, offering more multimedia flexibility and richer expansion potential via PCIe. If your priorities lie in business-class performance, ECC memory support, and robust multi-user capacity, the DS925+ is the clear winner. But for media streaming, home lab tinkering, and a wider hardware feature set, the TS-464 remains a very compelling alternative.

Synology DS925+ vs QNAP TS-464 – Software Specifications

When it comes to NAS platforms, hardware is only half the story—what truly determines a system’s long-term value is the strength, maturity, and flexibility of its software. Synology’s DSM (DiskStation Manager) and QNAP’s QTS/QuTS Hero are two of the most advanced NAS operating systems available today, offering extensive suites of services for backup, virtualization, hybrid cloud, media streaming, and AI-assisted surveillance. But while both OS platforms cover similar ground, their design philosophies, application depth, and supported workloads differ substantially. The Synology DS925+ and QNAP TS-464, though comparable in price and both aimed at prosumers and SMBs, unlock very different software experiences depending on the deployment goals—be it centralized IT infrastructure, media-rich home labs, or container-based edge computing.

With the DS925+, Synology leans into its strength in unified management and vertical integration. DSM 7.2 is optimized for reliability, simplicity, and scalability within Synology’s ecosystem. The DS925+ supports up to 8 virtual machines and 8 Virtual DSM instances through Virtual Machine Manager, offers extensive group and user quotas, and enables full integration with Synology’s cloud services (such as Synology C2 Backup, C2 Identity, and Hybrid Share). Its higher hardware ceiling allows for more active users: 150 on Synology Chat, 80 on Synology Drive and Office, and up to 8 simultaneous VPN connections. Backup capabilities are similarly robust, with a higher threshold of shared folder sync tasks and superior support for incremental snapshot replication. Surveillance Station on the DS925+ supports up to 40 IP cameras and benefits from reduced CPU overhead during continuous recording, even while handling concurrent backup or media indexing operations. DSM’s elegant UI, consistent updates, and tightly integrated packages make it ideal for organizations that value centralized IT administration and long-term platform stability.

On the other hand, the QNAP TS-464 running QTS 5 or QuTS Hero offers a more open and modular software ecosystem. While the Intel N5105 CPU imposes lower multitasking ceilings than the V1500B, QNAP compensates with a broader set of feature-specific applications and customization paths. The TS-464 supports virtualization through Virtualization Station (for VMs) and Container Station (for Docker + LXC), and unlike the DS925+, can output video directly via HDMI 2.0—allowing the NAS to act as a standalone Linux desktop, NVR, or HTPC via HybridDesk Station. QNAP also differentiates itself with Hybrid Backup Sync (HBS3), which enables multi-destination sync, deduplicated backup via QuDedup, and real-time disaster recovery tools not found in DSM. QVR Pro and QVR Elite offer an expansive surveillance suite with optional AI-powered analytics (e.g., face recognition, people counting) when paired with compatible QNAP AI apps. The inclusion of ZFS with QuTS Hero (an optional OS for the TS-464) enables inline compression, self-healing file systems, and block-level snapshots, which can be critical for data integrity in business scenarios.

QNAP also encourages expansion through its App Center, which includes over 150+ native and third-party apps, from Node.js and GitLab to Home Assistant, Ubuntu Station, and even Mattermost for self-hosted chat. While the system supports fewer concurrent users and VMs than the DS925+, its strength lies in feature breadth and system-level flexibility. Add-ons like 10GbE NICs, QM2 SSD accelerators, or Wi-Fi 6 cards via PCIe further extend its versatility, especially for hybrid edge workloads or multi-role deployments that evolve over time. In short, the Synology DS925+ is designed for administrative simplicity and long-term scaling, excelling in consistent performance across multi-user deployments with deep DSM integration. The QNAP TS-464, meanwhile, is a powerful sandbox for customization, offering greater freedom, multimedia functionality, and third-party integration—at the cost of some operational polish and software limits. Choosing between them depends on whether your priorities lie in predictable enterprise-grade execution or a more adaptable, feature-dense platform.

Synology DS925+ vs QNAP TS-464 – Hard Drive and SSD Compatibility

In 2025, Synology has taken its most aggressive step yet toward locking down hardware compatibility, and nowhere is this more evident than in the DS925+. Following years of gradual restrictions—starting with warnings for unverified drives and progressing to default white-listing only Synology-branded media—the DS925+ now represents a firm line in the sand. At the time of writing, this system will not allow DSM initialization if it detects hard drives or SSDs that are not officially listed on Synology’s compatibility list. This list includes exclusively Synology HAT5300/HAT3310 HDDs and SAT5200 SSDs, with no third-party Seagate, WD, Toshiba, Samsung, or Kingston media currently supported. Regardless of drive quality or performance, unsupported models will be outright blocked during system setup. While Synology claims this guarantees optimal reliability and performance within DSM 7.2, the move drastically reduces flexibility for users and integrators alike.

In stark contrast, the QNAP TS-464 embraces an open compatibility philosophy. It supports virtually all major consumer and enterprise drives—from Seagate IronWolf and Exos, to WD Red, Red Plus, and Ultrastar, as well as Toshiba N300/X300 and Samsung/Kingston SSDs—up to 24TB per drive (or higher as of late 2025). QNAP also maintains a regularly updated compatibility list, but crucially, this list is advisory rather than mandatory. Users can install any 3.5″ or 2.5″ SATA HDD/SSD, and as long as it meets the physical and electrical standards, the TS-464 will initialize without issue. This means integrators, home users, or small businesses can reuse existing drives or select from the most cost-effective options in their region—something that’s increasingly difficult to do on newer Synology units. Moreover, QNAP allows mixing and matching of drive brands and capacities within the same storage pool (especially under QuTS hero’s ZFS environment), giving users granular control over redundancy, performance tuning, and cache layering with non-proprietary M.2 NVMe SSDs. This openness also applies to QNAP expansion units, many of which continue to work even with completely mixed-brand storage configurations—something Synology’s newer expansion policies have started to restrict.

For users in regions where Synology-branded media is expensive, hard to find, or simply not justified for non-critical applications, this policy shift on the DS925+ can be a deal-breaker. It positions the system closer to an appliance model, where Synology controls not only the hardware and software, but the storage medium itself. While that vertical integration may improve long-term reliability for some enterprise users, it’s difficult to reconcile with the broader DIY NAS community that values choice and modularity. Ultimately, this creates a philosophical divide: QNAP remains open, modular, and adaptable, trusting users to make informed decisions about their storage media. Synology, in contrast, is consolidating control, with the DS925+ exemplifying a move toward a closed ecosystem—potentially alienating users who previously praised DSM for its balance of simplicity and flexibility. Prospective buyers need to weigh not just performance and features, but how tightly they want to be tied to a single vendor’s hardware roadmap.

Synology DS925+ vs QNAP TS-464 NAS – Which Should You Buy?

The Synology DS925+ is a 2025 refresh designed with clear intent: push performance, tighten control, and streamline the out-of-box experience. In contrast, the QNAP TS-464—released in late 2022—is a Swiss Army knife of NAS flexibility, packed with customization options, open compatibility, and enough horsepower to meet the needs of both power users and small business deployments. Choosing between them ultimately comes down to what kind of NAS experience you’re after: a controlled, polished, and tightly integrated environment, or an open, adaptable, and hardware-friendly platform. On raw performance, the DS925+ has the edge. Its quad-core, 8-thread AMD V1500B CPU delivers higher throughput for multitasking, virtual machines, and heavier concurrent services, and DSM’s user/service thresholds are notably higher as a result. Add in dual 2.5GbE ports by default, and it’s clearly a step ahead of the DS923+ predecessor 1GbE-only base configuration, and you are looking at a healthy upgrade in several ways in this refresh. However, QNAP claws back ground with its PCIe Gen3 x2 slot, allowing 10GbE upgrades, Wi-Fi cards, and even GPU acceleration in select use cases—something Synology removed entirely from the DS925+. In QNAP’s favor is also its support for real-time hardware transcoding, HDMI 2.0 video output, and direct-attached monitor access—making it a better fit for media-centric environments where local playback, Plex, or Kodi usage matters.

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