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.

$189 on Amazon (Check Here)	$549 on Amazon (Check Here)	$2499 on Amazon (Check Here)

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.

Value Series	Best All Rounder	Prosumer NAS
DXP2800 2-Bay NAS	DXP4800 PLUS 4-Bay NAS	DXP8800 PLUS 8-Bay NAS
$399 on Amazon (Check Here)	$699 on Amazon (Check Here)	$1499 on Amazon (Check Here)

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.

Value Series	Best All Rounder	Prosumer NAS
Nimbustor Gen 2 2-Bay NAS	Flashstor Gen 1 12-Bay NAS	Lockerstor Gen 3 8/10-Bay NAS
$369 on Amazon (Check Here)	$449-749 on Amazon (Check Here)	$1999 on Amazon (Check Here)

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.

Value Series	Best All Rounder	Prosumer NAS
F2-424 2-Bay NAS	F4-424 Max 4-Bay NAS	T9-500 Pro 9-Bay NAS
$369 on Amazon (Check Here)	$819 on Amazon (Check Here)	$1499 on Amazon (Check Here)

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.

Value Option	Best All Rounder	SSD Focused NAS
Aoostar WTR Pro 4-Bay NAS	Minsiforum MS-01 3/6-Bay NAS	Lincplus Lincstation N1 6-Bay NAS
$399-799 on Amazon (Check Here)	$399 on Amazon (Check Here)	$399 on Amazon (Check Here)

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

Synology vs EVERYONE ELSE – Conclusion and Verdict

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

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

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

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

 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.

---

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 Terramaster NAS – Conclusion and Verdict

Comparing Synology and TerraMaster in 2025 ultimately highlights a clear philosophical divide between the two NAS brands. Synology continues to build upon a long-standing focus on refined software, tight integration, and enterprise-grade security. Its DSM platform remains one of the most polished and feature-rich operating systems in the NAS space, offering a wide selection of first-party tools for backup, surveillance, virtualization, and secure access. However, this ecosystem is increasingly closed, with stricter hardware compatibility requirements and limited support for third-party drives, SSDs, and expansions. For users who prioritize reliability, ease of use, and support from a mature software ecosystem, Synology remains a compelling—if sometimes restrictive—option.

Synology NAS– 5 Strengths vs TerraMaster in 2025 Superior software polish: DSM offers a more consistent, responsive, and user-friendly interface, ideal for beginners and pros alike. Better security infrastructure: Features like a dedicated PSIRT, frequent vulnerability disclosures, and a bug bounty program give Synology the edge in system safety. Mature first-party apps: Key tools like Active Backup for Business, Surveillance Station, and Synology Drive are more refined and feature-rich than their TOS counterparts. Streamlined management: Built-in tools for snapshots, monitoring, and backup offer a more centralized and automated experience. Longer ecosystem stability: Greater long-term support for software versions and consistent patch cycles provide peace of mind for business use. Cons: Strict hardware compatibility: Recent models (e.g., DS925+) restrict use of non-Synology drives and SSDs, frustrating users seeking flexibility. Less hardware value per dollar: Generally more expensive for equivalent CPU, RAM, and port configurations.

TerraMaster, by contrast, leans into flexibility and hardware value. Its broad portfolio includes NAS units ranging from entry-level to high-performance multi-bay SSD systems, often at lower price points than Synology’s equivalents. TOS 5.1 and the newer TOS 6 have brought meaningful improvements in UI and functionality, while still maintaining a more open approach to compatibility and user customization. Features like native Jellyfin support, VirtualBox VM deployment, and the ability to install TrueNAS or Unraid without voiding warranty make TerraMaster a standout for DIY-leaning users or those with niche requirements. However, its software, while improving, does not yet match the polish or depth of Synology DSM, especially in areas like virtualization, surveillance, and enterprise security.

TerraMaster NAS – 5 Strengths vs Synology in 2025 Better hardware value: Offers more powerful CPUs, RAM, M.2 slots, and 10GbE in the same or lower price bracket. Flexible OS options: Users can install TrueNAS, Unraid, or other OSes without voiding the warranty, offering unmatched flexibility. Open storage support: No restrictions on drive brand or SSD use, supporting Seagate, WD, Toshiba, Samsung, and more. More aggressive expansion options: TOS systems often support more USB and hybrid expansion units across the portfolio. Integrated Jellyfin support: TerraMaster includes native Jellyfin installation without relying on Docker or community packages. Cons: Less mature software ecosystem: TOS apps are less polished and lack some advanced features found in DSM tools. Weaker track record on security: Past vulnerabilities (e.g. Deadbolt) and slower public patching place more responsibility on the user for hardening.

In the end, choosing between Synology and TerraMaster depends heavily on user needs and expectations. Synology suits users who want a highly stable, all-in-one solution with minimal configuration and long-term support. TerraMaster offers greater adaptability and value for power users who are comfortable managing third-party apps and want to stretch their hardware investment further. Neither approach is inherently better—each has its strengths and trade-offs. Buyers seeking a tightly controlled, secure environment may gravitate toward Synology, while those who value hardware scalability, open software choices, and affordability may find more freedom with TerraMaster.

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.

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.

	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.

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

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

UniFi UNAS Pro 6 Months Later – The TL;DR

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

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

• Enabled OneDrive and Dropbox as new cloud backup destinations.

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

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

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

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

• Support file generation now available for diagnostics.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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