Synology NAS vs EVERYONE ELSE – Which Is Best?

If Not Synology? Which Other NAS Brand Should You Choose?

It’s an odd question, but with Synology arguably making some rather higher business and enterprise decisions in recent years, there have been increasing queries about who would fill the void if they moved onwards and upwards. As Synology holds such a powerful position in the NAS market, their absence would certainly lead to quite the battle of strength from other players. The obvious answer would be QNAP, a brand that has a similar history to Synology (over two decades in the business, Taiwan-based, in-house OS, numerous 1st-party tools, home and business solutions, etc.), but in 2025, the reality is nowhere near as clear-cut. Younger established brands that have jockeyed for 3rd position, such as Asustor and Terramaster, have been challenged by several startups (ZimaCube and Zimaboard 2, Orico’s Cyberdata Vault, to name just two) entering the fray, as well as established brands like UGREEN, which are expanding their business into the NAS sector. If Synology, for whatever reason, ceased to occupy this important user class of private turnkey server ownership, who would be best placed to occupy it?

How, Where and Why Has Synology Changed?

Synology’s rapid change in business stance to be more enterprise/hyperscale-focused comes at the same time as their frequency of more entry-level, small business, prosumer, and enthusiast solutions has dropped. The regularity of smaller 2-Bay and 4-Bay solutions has noticeably decreased, and the hardware they feature has changed to accommodate more business-type use. This by no means suggests that the brand is making moves to exit these user groups (indeed, support of DSM and the latest revision DSM 7.2.2 extends to all existing users up to many systems released in the late 2010s). However, there has been plenty of user outcry from existing users and potential customers on the architecture of both DSM and the recent releases that exacerbate users to move away from the brand and spend their allocated budgets elsewhere. Synology still comfortably sits ahead of its competitors in terms of software, features, and the UX of their platform, but many changes in policy and support mentioned below have started this trend:

  • Changes in 3rd-party HDD compatibility on systems above the 8-Bay scale, prioritizing their own 1st-party labeled HDDs and SSDs, as well as reducing the presentation and compatibility listings on their site significantly.
  • Changes in the choice of internal hardware featured in their systems to be more focused on business file processes and less on multimedia use.
  • Comparatively smaller increases in base hardware between refreshes of individual series (e.g., J4125 and V1500B CPUs in 2024 launch devices, despite first appearing in 2019/2020).
  • Considerable increased focus on software enhancements over hardware (not a bad thing, but an undeniable fact).
  • Increased proprietary hardware support over 3rd-party (e.g., Synology-only Memory modules, custom 10GbE adapters like the E10G22-T1, Synology-only M.2 SSDs for Pool Use).
  • An increasing number of cloud subscription services getting newer features, while local services remain secure and stable but static.
  • New product focus shifting towards newer larger-scale solutions like the evolving GridStation series, Active Protect subscription system, and C2 innovations.
  • The predicted elimination of the J entry-level series in favor of the pre-populated and software-streamlined BeeStation.

All of the above are small factors in themselves, but add them all up, and you see small but important stepping stones toward a gear shift in Synology’s target demographic. So, if Synology were to intentionally or inadvertently begin to move outside of these user groups of home, small business, and enthusiast, who stands to fill this space and grow?


QNAP vs Synology?

As mentioned earlier, QNAP stands to be the most likely contender to fill this space. With over 20 years of history, a larger range of hardware solutions than Synology, and software that does pretty much everything Synology’s does, they have been consistent competitors. However, inconsistencies in user experience, conflicting UIs, and a tendency to try to do “too much” have resulted in their losing ground to Synology in terms of software. Add to this the negative brand impact of security incidents in 2020-2022, which tarnished their reputation around security and safety, requiring serious improvement. To the brand’s credit, they have made considerable internal culture changes on this subject, adding bounty programs, tightening system defaults, increasing pen testing, introducing several system security scanning tools, disabling things like SSH and admin super user accounts as standard, and more.

In terms of hardware, they have mostly stuck to what works, refreshing existing product families at the same rate of 2.5-3 years for desktop small-medium scale, and 3-5 years for larger scale. They have also introduced significantly more recent CPUs from both Intel and AMD, as well as 2.5GbE as standard on their solutions at the same price point as 1GbE. If it weren’t for the damaging brand harm caused by the Deadbolt/QSnatch/Qlocker ransomware attacks, I think Synology would have been significantly challenged by QNAP in the last 2-3 years across all fronts. However, the setback to QNAP’s reputation reduced this growth potential significantly, and in the last two years, we have seen an increasing number of new names pop up in NAS that have also harmed QNAP’s appeal to users in terms of hardware value, the thing they could always be relied upon to beat Synology on. QNAP would still stand to become the ‘top dog’ in the event of a Synology exit (Synexit?) from the low-to-medium tiers of NAS storage, but many new players have entered the field, such as…


UGREEN vs QNAP?

Largely known for their power adapters and PC accessories, a year ago UGREEN had practically no real presence in the world of NAS. They had a smaller scale and more entry-level range of solutions that were limited to the East, but aside from that, they were complete outsiders. Fast forward to now, and following a successful and well-marketed Kickstarter campaign that raised millions of dollars, they are now a provider of genuinely impressive turnkey NAS solutions—the NASync series. The key word there is “turnkey”, as in they are providing both the hardware and the software. They could have just rolled out their hardware and made it OS-free (i.e., “Here’s a ready-built server, now go install UnRAID or TrueNAS”), but instead, they opted to produce and include an impressively responsive NAS OS in UGOS. Genuinely challenging the feature set of the likes of Asustor and Terramaster, as well as the design of Synology and the hardware level of QNAP, UGREEN has made a rapidly growing name for itself in the small-to-medium NAS sector.

They definitely lack the range of solutions that those other brands offer, with only 6 solutions currently available (the DXP2800, DXP4800/PLUS, DXP6680, DXP8800, and DXP480T), and no rackmount solutions yet, but it’s a solid start. Equally, their software, although fluid and responsive in nailing down the NAS fundamentals, lacks many of the more impressive AAA+ solutions that are offered by the bigger brands. Lastly, although they raised a considerable sum during the crowdfunding, they do not have the global support, offices, or availability of their long-running NAS competitors—with solutions only being available in two regions, the US and Germany. All of these factors add up to a brand that is poised to make even bigger splashes in the years to come but is perhaps not quite ready to replace the big dog, Synology, just yet!


ASUSTOR vs Synology?

Always the bridesmaid, but never the bride, Asustor is a brand that has been around in the world of NAS in one shape or form for quite a few years. They are one of the mainstream Taiwanese brands in NAS that has always ‘been there’, but it is only in the last 4-5 years that they have been making sizable moves to take on both Synology and QNAP. One of the main ways in which they pursued this is by developing numerous features in both hardware and software that are available from their competitors individually. So features such as M.2 NVMe-focused storage systems, BTRFS support, WORM locking, 2.5GbE/5GbE support, HDMI output via a dedicated GUI, and more are features available on Synology and QNAP to some extent, but only Asustor rolls them under one brand umbrella. So, how poised are they to fill a void if Synology moved out of this space?

Well, from a hardware standpoint, Asustor is in a very good position. Them being Taiwan-based will certainly soothe concerns that have grown around Chinese companies and data storage solutions. Equally, their hardware has evolved rapidly in their last two generations to feature some genuinely unique solutions that are either specific to the platform or priced at a level that makes them genuinely competitive against DIY and BYO solutions. Systems such as the Flashstor series, Lockerstor series, and even value offerings like the Drivestor are surprisingly well equipped. They are not quite on the same level of hardware as QNAP (who have a significantly more diverse hardware portfolio), but they are fleshing it out very well.

However, it is the software of Asustor (ADM) that is unfortunately where the brand is a little more timid. They have a NAS OS, numerous client tools for Windows, Mac, iOS, and Android—and they nail down the bulk of the application fundamentals for storage management, multi-site backup handling, multimedia playback, containers, and more. But the platform lacks a few of the more AAA/desirable services, such as AI-powered photo recognition, a 1st-party VM tool, ZFS support, and ultimately is a little more reliant on 3rd-party applications to fill the gaps. They have recently countered this by officially detailing that they support users who buy Asustor hardware to go ahead and install 3rd-party NAS software like TrueNAS or UnRAID without it harming your warranty—so they know they are not leading the pack in terms of their own ADM NAS software but do make noticeable user concessions. With new hardware on the horizon in the Lockerstor Gen3 and Flashstor Gen2 (both of which see a significant bump in hardware profiles), we might see some impressive moves from Asustor in 2025. I just think they still have some ways to go before they can fill any potential void that Synology might leave.


TERRAMASTER vs Synology?

Terramaster has been jockeying for the NAS 3rd place spot with Asustor for well over a decade at this point, and much like their opponent, they have been good at integrating individual features from both QNAP and Synology into their own NAS hardware and TOS platform, but to a larger degree than Asustor. For example, their OS provides largely everything that Asustor ADM does (including TrueNAS/UnRAID support without voiding your warranty) but adds to this with an AI photo recognition platform, their own VM tool, and an impressive Isolation Mode that can sever the system at the click of a button from remote access, 3rd-party PHP, and any external requests (necessitating a restart to disable). However, as this brand is a Chinese brand, there will always be question marks raised by users about how this system compares with Taiwanese-based systems. This is a little unfair, given that Terramaster, Asustor, and QNAP were all successfully hit by the same ransomware attack (Deadbolt) a few years back, so there was plenty of ‘vulnerability’ to spread around!

In terms of hardware, Terramaster has been making some impressive and aggressive strides in this area—with the recent launch of their 3-part F4-424 Intel NAS series (Standard, Pro, and MAX), the release of two 8-bay M.2 NVMe 10GbE equipped systems (the F8 PLUS and F8 SSD PLUS), and new desktop and rackmounts hot on their heels. They have also scaled up the design to better improve cooling, efficiency, and just general visual appeal.

However, much like Asustor, their software is just not able to challenge the standard that Synology has set. For buyers looking for smooth and easy utilization like Synology, Terramaster’s TOS has the danger of feeling a little clunky. Their latest release, TOS6, brings new features, software standards, and design to the mix, but it lacks the range of mobile applications, desktop client tools, and consistent UX/presentation that Synology seems to do so well. Terramaster is a fantastic value-for-money choice, and I would argue they have significantly scaled up the level of hardware and software utility they provide year on year. But they still have a way to go before they can hit the same notes as Synology DSM yet.


WD / Netgear vs Synology?

This is a pretty short one! The answer is no! Both WD and Netgear have regularly reduced their hardware ranges and the frequency of software updates these last few years, and although there are a decent range of business file server systems still being released, the general home/enthusiast/prosumer level of hardware is pretty poor and uninteresting compared to everyone else on this list so far. I cannot help but get the feeling that, aside from some basic backup NAS systems that are still listed at the majority of retailers, the bulk of their range has been in circulation for 5-6 years now without any refresh in sight. For basic target file/folder storage, these systems still provide some limited modern NAS utility, but overall, they are a fairly weak alternative to Synology’s offerings in 2025.


A UniFi NAS?

With increased mentions and leaks online towards a potential NAS in the works from UniFi, this could be a very credible alternative to Synology in terms of software UX and presentation. UniFi, and its incredibly user-friendly UX featured on their Switch, Router, NVR, and Dream Machine combination systems, is where UniFi shines. No doubt any UniFi NAS solution would need to similarly blend into their ecosystem to the same degree. That said, if they were to launch a system, all their experience in the fields of network management, router security, and surveillance systems might not necessarily translate into a similar pedigree in network-attached storage. It’s hard to discuss how or if UniFi could fill any market space that a potential Synology absence would create, as they do not have any systems out in the market to make an informed decision. This is for the “To Be Continued…” pile!


Drobo vs Synology?

No…just…no. See Video Below:


IceWhale / ZimaCube

This is a very interesting one. 2023 and 2024 saw several companies arrive in the turnkey NAS space via the crowdfunding route (we already discussed UGREEN as the biggest example), wanting to break into the market. However, IceWhale benefits from having already launched two previous successfully fulfilled campaigns and is just completing their third one with the ZimaCube NAS system. Arriving with the lightweight containerized platform Zima OS (a modified version of their existing Casa OS), this new series is pretty impressive for its scale and price point at launch. Add to that the significantly unique design, impressive use of 10GbE and Thunderbolt over IP, and a 6x HDD / 4x NVMe system in a compact case, and you can see why they have made a fairly significant splash for a brand that is comparatively unheard of compared to Synology, QNAP, etc.

However, as robust as their range of solutions is (ZimaBoard, ZimaBlade, and ZimaCube), the software is still very rudimentary compared to the bulk of other browser GUI and more “operating system”-stylized UX. There are virtually no client applications, except for their own system search and connection client tools. An eventual successor to Synology, if they moved upwards toward bigger and more business-oriented solutions, would need to hit the software functionality and user experience exceedingly early and exceedingly well.

Mini PC Brands – Lincplus, Aoostar, etc.

This is an odd one. There have been a large number of solutions appearing on sites such as AliExpress that arrive as “OS-Free” services, allowing a user to get a pre-built NAS hardware solution (i.e., no need to build one yourself, which takes longer and requires a degree of technical understanding). The end user can then choose to install popular and well-established solutions like TrueNAS, UnRAID, OpenMediaVault, and more.

This serves as an impressively economical solution and has significantly grown in popularity in 2023/2024, but these 3rd-party software platforms lack a lot of the ease of use and quality of life client tools for modern devices that Synology features. Indeed, despite efforts like UnRAID 7 making its day-to-day use much easier, and TrueNAS working with HexOS for a more user-friendly output, these still pale in comparison to DSM and will also require a greater degree of technical user input in the long term to maintain stability, versus Synology’s rather more “it takes care of itself” design.


Synology vs EVERYONE ELSE – Conclusion and Verdict

If Synology were to leave the home/enthusiast/prosumer/small business tier very soon, I do think QNAP would stand to reoccupy this ground. However, give it 2-3 years, and I do think players like Terramaster, Asustor, and yes—even UGREEN—are poised to give QNAP some serious consumer competition. No doubt Synology is still keeping an eye on their competition (big and small) and would not willingly or easily give up this sector without a fight. However, there is no denying that the turnkey NAS industry is no longer the 2-3 horse race it was just five years ago!

Synology vs Terramaster NAS – Which Should You Buy?

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

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

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

Synology vs Terramaster NAS – Hardware Solutions Compared

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

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

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

Synology vs Terramaster NAS – Storage, Compatibility and Scalability

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

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

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

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

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

Synology DSM vs Terramaster TOS NAS – Software Comparison

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

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

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

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

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

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

Synology vs Terramaster NAS – Security and Safety

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

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

Security Feature Synology DSM TerraMaster TOS Notes
System Hardening Proactive hardening (limited root access, secure defaults) Moderately hardened; more configurable access Synology limits risky configurations by design
Security Scanner Built-in DSM Security Advisor with customizable scan depth TOS Security Center (less detailed on TOS 5.x) Synology provides more actionable alerts
2FA Support TOTP-based (authenticator apps, email) TOTP-based Parity on two-factor authentication
SSL Certificate Support Native Let’s Encrypt + custom certs via GUI Let’s Encrypt + custom certs via GUI Equal support, easy HTTPS setup
Firewall Management GUI-based port/IP firewall with profiles Firewall settings available (less granular) Synology allows more granular firewall policy creation
Isolation Mode / Kill Switch ❌ Not available ✅ Isolation Mode disables all external access with one click Advantage: TerraMaster for emergency lockdowns
Vulnerability Response (PSIRT) Dedicated PSIRT, public advisories updated monthly Less frequent disclosure, fewer details published Synology actively discloses and patches
Security Bug Bounty Program ✅ Yes – active white-hat reward program ❌ No public bounty program known Synology engages with global researchers
Third-Party App Restrictions Limited for security; sandboxed services More open but requires user discretion Synology prioritizes closed ecosystem safety
Remote Access Protection QuickConnect includes traffic relay + DDNS + 2FA TNAS.online DDNS with isolation toggle Both offer encrypted remote access, but Synology uses multiple layers
Malware Detection Real-time malware scanner, browser warnings Included scanner, but simpler in scope DSM scanner is more active and integrated
Backup Verification Integrity verification in Active Backup TerraSync + cloud/USB support (manual checks) DSM offers automated backup health reports
Surveillance Hardening Encrypted video storage + HTTPS + IP blocklist Surveillance App with HTTPS, still evolving Synology Surveillance Station is more mature and secure
Ransomware History 2014 “SynoLocker” (quickly patched) 2021–22 “Deadbolt” attacks (multiple waves) TerraMaster more affected in recent years
Update Frequency Frequent monthly patches Less frequent, varies by model DSM has a consistent schedule and transparency

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

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

Synology vs QNAP in 2025

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

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

Synology vs QNAP NAS – Hardware Comparison

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

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

Synology vs QNAP NAS – Storage Services and Scalability 

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

  SERVICE SYNOLOGY QNAP Notes

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

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

Synology DSM vs QNAP QTS/QuTS  – Software Compared

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

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

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

Synology vs QNAP NAS – Security 

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

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

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

Synology vs QNAP NAS – Price Point and Value 

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

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

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

Synology vs QNAP NAS – Conclusion and Verdict 

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

Synology vs UGREEN NAS (in 2025)

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

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

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


Synology vs UGREEN NAS Hardware Compared 

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

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


Synology DSM vs UGREEN UGOS NAS Software & Services

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

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

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

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

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


Software Comparison

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

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

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

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


Synology vs UGREEN NAS – Security 

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

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

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

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

Synology vs UGREEN NAS – Pricing and Value 

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

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


Synology vs UGREEN NAS – Verdict & Conclusion

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

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