A Review and Full Overview of the UniFi UNAS NAS OS

Update – The UniFi UNAS Pro is now back in stock in the U.S and UK HERE. EU Stocks have been good regardless!

The UniFi UNAS Pro is Ubiquiti’s first serious foray into the NAS market, and it introduces a distinct software platform designed to cater to users already embedded in the UniFi ecosystem. While UniFi is more renowned for its networking hardware and software, the UNAS Pro represents a bold attempt to bring a streamlined, cloud-connected NAS solution that mirrors the simplicity of their existing products. The UNAS Pro offers a single-pane-of-glass interface that simplifies complex NAS management tasks. This makes it particularly attractive to users who may be transitioning from more established brands like Synology or QNAP, but are looking for a solution that integrates easily with their current UniFi products. As we dive deeper into the system, it becomes clear that while it is in its early stages, the software holds promise for both individual users and organizations seeking a hybrid storage and backup solution.

Logging into UniFi UNAS Pro and Remote Access

Accessing the UniFi UNAS Pro can be done through both local network connections and remote access via the UniFi Site Manager. The interface is designed to feel intuitive and familiar to users who have interacted with other UniFi products. For remote access, users can authenticate their credentials through the UniFi Identity application, which enhances security by providing a layer of credential verification and access control.

This ensures that both administrators and regular users can securely log in, regardless of whether they are on the same local network or accessing the NAS from a remote location. One of the most anticipated features is the upcoming SMB mounting tools, which will allow users to mount the drives directly to their local file manager – an extension of the ‘Identity’ application, that will allow for faster and easier local drive mounting. This addition will provide a more seamless experience for local network users, making file management significantly easier.

System Overview: Storage, Temperature, and Resource Utilization

Once logged in, users are presented with a dashboard that provides a comprehensive overview of system resources, storage, and temperature. The software offers real-time data on total storage usage, system temperature, and resource utilization, such as the percentage of CPU and memory currently being used. The NAS is powered by a quad-core ARM-based processor and comes with 8GB of RAM, which provides ample power for handling standard NAS tasks such as backups, file sharing, and even moderate multi-user environments.

While the system temperature is shown, the current version does not yet display individual drive temperatures, although this is expected in future updates. The resource usage breakdown is clear and easy to understand, showing memory consumption, which hovered around 31% in testing. This indicates that the NAS has more than enough headroom for moderate workloads and remains responsive even during peak activity.

Storage Management: Drive Population and RAID Configuration

The storage management tools in the UniFi UNAS Pro are designed to accommodate a variety of setups, making it flexible enough for both beginners and seasoned NAS users. One notable feature is the ability to gradually populate the NAS with drives over time.

This means that users don’t have to fill all the drive bays at once and can expand their storage capacity as needed. New drives are automatically absorbed into the single storage pool, although the current system only supports a single pool, which limits more advanced multi-pool configurations.

The system does support mixed drive configurations, but all drives are classified based on the smallest capacity drive in the array (AKA – you CAN use different drives, but you will lose the extra storage benefits of alternatives such as Synology Hybrid RAID SHR or Terramaster TRAID).

At launch, the system supports RAID 10 for data protection, which offers a good balance between redundancy and performance. However, RAID 6, which provides better redundancy at the cost of performance, is expected to be introduced in future software updates. Users can also configure a hot spare, ensuring that a spare drive is ready to automatically rebuild the array if another drive fails.

Backup Tasks: Setup and Options

UniFi UNAS Pro includes a straightforward and intuitive backup task setup process, allowing users to create both local and remote backups with minimal effort. The software supports backups to other UNAS systems within the same network or linked through the UniFi Site Manager, and it can also integrate with popular cloud storage services like Google Drive.

The backup system is flexible enough to allow users to schedule backups, decide whether to overwrite existing backups, or create entirely new directories for each backup session. However, the software is currently lacking advanced features like automated failure handling, where the system would retry a failed backup or send an alert. This is something that is expected to improve in future software versions. Cloud backup integration is user-friendly, leveraging QR codes for simple account linking, and users have the ability to set detailed rules for backup frequency and data retention.

File Services: SMB, Time Machine, and Connectivity

The file-sharing capabilities of UniFi UNAS Pro are built around widely used protocols such as SMB, which ensures compatibility with Windows environments, and Time Machine, which offers seamless integration with macOS for backups. Users can access their files via local network connections or remotely through a variety of interfaces provided by the system.

The NAS supports both 10G SFP and traditional copper-based Ethernet connections, providing high-speed local access, which is ideal for demanding workflows like video editing or large-scale file transfers.

In addition to these standard file services, the software allows for encrypted drives, which can be locked and unlocked as needed. These encrypted drives provide an extra layer of security, especially for sensitive data, by ensuring that data remains inaccessible during system reboots or maintenance.

User Management: Roles and Permissions

The user management system within the UniFi UNAS Pro software is both flexible and secure, offering administrators the ability to create both local and remote users with varying access levels. Admins can easily create different roles and assign them to users, providing granular control over which storage areas and features each user can access.

For instance, it is possible to create a user with read-only access to specific drives or folders while granting full access to others. Integration with UniFi Identity enables more advanced features, such as role-based access control and multi-factor authentication.

For organizations, this system is invaluable as it allows each user to have a dedicated storage area, with the ability to assign access rights to shared folders. This makes it particularly suitable for businesses where different departments or teams may need different levels of access to shared resources.

Snapshots and Shared Folder Management

Snapshots are a useful feature in the UniFi UNAS Pro software, providing a way to restore previous versions of files or entire folders. However, snapshots are not a true backup solution; they are better described as a tool for turning back time on specific data. One limitation of the snapshot system is that if a snapshot in the middle of a series is deleted, all subsequent snapshots become invalid.

This can create challenges when managing long-term data versions, so careful management of snapshots is essential. Creating and managing shared folders is a straightforward process. Admins can easily set up new shared folders, assign users, and configure storage limits. The system also supports share links, which allow users to share files and folders with external users through expiring links or password-protected URLs. These features are critical for users needing to collaborate or share large amounts of data with others outside their immediate organization.

System Responsiveness and Performance

Despite its relatively simple design, the UniFi UNAS Pro software is responsive and efficient, even under load. During testing, the system remained responsive while accessed remotely over a 100 Mbps connection, which is far from the fastest available bandwidth. This is a testament to the system’s resource management, where memory usage generally remains around 31% of the total 8GB. The software is capable of intelligently managing resources, allowing it to keep performance smooth even during periods of high demand. This level of responsiveness is particularly important for users accessing the system remotely or those relying on it for critical business operations, as it ensures that the system remains functional even when bandwidth is limited.

Settings and System Configuration

The settings and system configuration options within UniFi UNAS Pro are comprehensive, offering everything from backup management to network configuration. One standout feature is the ability to schedule system configuration backups to UniFi’s cloud platform. This ensures that users can quickly restore system settings, user configurations, and shared folder structures in the event of system failure or data loss.

The system also allows for local backups, which can be restored when necessary. Console settings allow users to adjust basic parameters like LED behavior and display options, but more advanced features like hard drive hibernation and scheduled power management are still absent. Future updates are expected to introduce these features, making the system more competitive with established platforms like Synology and QNAP.

Network Configuration and Final Thoughts

The network configuration options in UniFi UNAS Pro are somewhat limited compared to more advanced NAS platforms. While users can adjust settings for individual network ports, features like jumbo frame control and MTU adjustments are currently missing. This may not be a significant issue for most users, but those with more demanding network setups may find these omissions limiting. Overall, UniFi UNAS Pro presents a compelling option for users already invested in the UniFi ecosystem. While it lacks some of the advanced features found in Synology and QNAP systems, it is clear that the platform is evolving rapidly. As Ubiquiti continues to develop the software, users can expect additional functionality, such as container deployment, deeper integration with UniFi Protect, and better file-sharing tools. For those looking for a NAS solution that integrates seamlessly with their UniFi environment, the UNAS Pro is a promising choice with plenty of room for growth.

Why is a UniFi NAS a big deal?

It’s a good question. When it comes to turnkey, ready-to-deploy NAS systems for enthusiasts and businesses, there are already some very well-experienced and established providers in the market. Why is it that Ubiquiti and UniFi think they can bring something new into this already well-fleshed-out solutions game? That single ecosystem advantage. That is pretty much what UniFi is all about. UniFi, as the name suggests, is about the unification of all of the devices in your network, all being managed, controlled, and securely gated by the UniFi network controller. The terminology has changed a few times in recent years, but the end result is the same—having your network equipment, wireless connectivity, surveillance systems, and security all managed within a single one-party ecosystem. With NAS products and private servers growing ever more popular, many long-established UniFi users have had to inject a third-party NAS solution from the likes of Synology or QNAP into this clean ecosystem. This means bringing parallel software UIs and UXs into the equation, as well as increasing the attack surface and vectors that managing multiple security updates across the board can introduce.

Equally, UniFi has an exceptionally well-established history for its network and internet security services, combined with an increasing number of their solutions arriving with storage services in place already. Systems like the UNVR series and the UniFi Dream Machine systems all arrive with SATA storage capabilities included, and some more hands-on users have gone ahead and soft-modded UniFi Protect surveillance systems into having a modicum of NAS ability. It doesn’t take much searching online to see that there has been a demand for a first-party network-attached storage solution by UniFi users for an exceptionally long time. Although they have clearly taken their time on it, is this the NAS system that users have been waiting for?

UniFi UNAS Pro Review – Quick Conclusion

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

UniFi UNAS Pro vs Synology NAS – Price

When it comes to pricing, Synology and UniFi are positioned at different ends of the spectrum, catering to a wide variety of users with different needs and budgets.

UniFi‘s UNAS Pro, priced at $499, offers a 7-bay rackmount NAS with 10GbE networking capabilities, making it a highly competitive option, particularly for users already embedded in the UniFi ecosystem. This pricing is aggressive for a rackmount system, as most NAS systems with similar features are priced higher. The UNAS Pro is designed to offer an affordable entry point into the world of NAS for small businesses, IT enthusiasts, or existing UniFi users looking to expand their infrastructure with file storage.

By comparison, Synology offers a wide range of NAS devices, starting with affordable 2-bay home systems and scaling up to high-end rackmount systems designed for large enterprises. For example, the Synology DS923+, which retails around $499, provides a 4-bay desktop solution with expandable 10GbE support and an x86 processor, giving it a slight edge in performance over the UNAS Pro for the same price. However, Synology’s rackmount offerings, such as the RS422+, start at $599 for a 4-bay system, and prices quickly rise for larger models with more features and higher-end hardware.

The price difference between these two brands becomes more apparent as you explore Synology’s higher-end options. Their enterprise-grade NAS systems with features like redundant power supplies, dual controllers, and PCIe expansion slots can cost well over $1,000, whereas UniFi’s UNAS Pro remains a single, relatively fixed offering at the lower end of the price range.

In terms of long-term value, UniFi clearly offers a more affordable entry into the NAS market, particularly for users who already use UniFi’s networking products.

UniFi NAS vs Synolgoy NAS – Software Presentation

The software interface of a NAS system is crucial to its usability, and here, the differences between Synology and UniFi are stark. Synology’s DiskStation Manager (DSM) is known for its user-friendly, graphical interface that feels similar to using a desktop operating system. DSM provides users with a desktop-like environment, complete with drag-and-drop functionality, customizable wallpapers, and a taskbar for quick access to applications. This layout makes it easy for both novice and experienced users to navigate the system, install applications, manage files, and perform backups. The interface is intuitive, with large icons and a clean, modern design that encourages exploration and productivity.

In contrast, UniFi’s UNAS OS is designed with a more text-based, data-centric approach. Borrowing from UniFi’s successful networking interfaces, the UNAS OS focuses heavily on analytics and system monitoring, making it ideal for users already familiar with UniFi’s ecosystem. The interface provides detailed insights into system performance, file transfer speeds, and network activity, which are displayed in simple, granular dashboards. While it may not have the graphical polish of Synology’s DSM, the UNAS OS excels in presenting network data and providing tools for IT administrators who prioritize system efficiency over aesthetics.

UniFi’s single-pane design keeps all relevant information within reach, but it lacks the app-based approach that Synology users are accustomed to. Synology’s DSM, on the other hand, organizes features into discrete applications, making it easy to jump between tasks like file management, backup scheduling, and multimedia streaming. Below is a table that summarizes the key differences in software presentation between UniFi and Synology at a glance (bigger chart soon, don’t worry!):

Feature	UNAS OS	DSM 7.2
User Interface Style	Text-based, network analytics	Desktop-like, graphical interface
Customization	Minimal	Quite customizable (wallpaper, layout, shortcuts)
Mobile App Support	Limited	Extensive
Third-Party App Store	No	Yes (Synology Package Center)
Storage Interface	Simplified, easy to use	Comparatively Advanced, easy-to-use

Verdict on Software Presentation: Synology’s DSM clearly offers a more engaging and customizable user experience, while UniFi’s UNAS OS focuses on providing a streamlined, efficient interface for users already familiar with the UniFi ecosystem. Users looking for an intuitive, desktop-like experience will prefer DSM, while those focused on networking performance and integration may find the UNAS OS more suitable.

Synology vs UniFi – Software Security

Security is paramount for NAS systems, as they often store sensitive data and operate in environments where external access is necessary. Both UniFi and Synology offer security features, but they take different approaches based on their respective ecosystems.

Synology DSM offers a full suite of security features, including two-factor authentication (2FA), firewall configuration, and behavioral analysis to monitor suspicious activities. DSM allows users to integrate third-party security tools, such as Google Authenticator or OTP services, providing flexibility for businesses that already use external authentication systems. Additionally, DSM includes SSL certificates and IP blocking, ensuring that only trusted users can access the system. Synology also has an inbuilt security scanner that checks the system periodically (ad hoc if you want too) for potential weaknesses in the system configuration,which can be set to a home or business class standard (custom too).

UniFi’s UNAS Pro integrates security measures more closely tied to the broader UniFi ecosystem. 2FA is also available but typically relies on UniFi’s own authentication services, such as the UniFi Identity App. This may be limiting for users who prefer third-party authentication tools. The UNAS OS benefits from UniFi’s enterprise-grade network security tools, such as IP monitoring and network relay services, which are crucial for maintaining the integrity of the entire network infrastructure. However, its NAS-specific security tools, such as DOS protection and auto-lock, are less extensive than Synology’s.

UniFi’s focus on network-level security makes it ideal for businesses that already use UniFi networking hardware, as the UNAS Pro can integrate seamlessly with UniFi switches and security gateways.

However, Synology’s in-system security tools are more comprehensive, making DSM a better choice for users who prioritize NAS-specific security features. It’s also worth remembering that the majority of remote access security features of the UniFi UNAS Pro are locked into use with he UI.COM / UniFi account system. You cannot use 3rd party 2FA/OTP applications or use 3rd party remote access services like Tailscale or Teamviewer.

That said, BOTH systems provide a regular rotation of security and feature system updates over the years that they will be in operation, so the latest security fixes and improvements that are needed to combat vulnerabilities that appear i nthe wild can be automatically adjusted for. However, UniFi does provide a little something extra with simple modular update control. Synology DOES allow you to install updates on the whole OS and/or individual Apps (or be alerted about them but action when it best suits your needs for a restart), but the UniFi UNAS Pro presents this in a much easier to action single option, that allows for full update control to be more granular for either the OS or the application service(s). It’s no more/less than the synology DSM option, but it is presented a great deal more cleanly.

UniFi NAS OS vs Synology DSM – Software Features

When comparing the software features of Synology and UniFi, it’s clear that Synology has had years to develop a rich, feature-packed operating system, while UniFi‘s UNAS OS is still in its infancy. Synology DSM (DiskStation Manager) is known for its vast ecosystem of first-party and third-party apps, which provide a wide array of functionalities beyond basic file storage.

By contrast, UniFi UNAS OS focuses on core NAS functions, offering fewer features but maintaining tight integration with UniFi’s networking solutions.

Synology DSM is renowned for its wide range of software features that cater to home users, small businesses, and enterprise environments. DSM is designed to be a complete solution, offering robust support for file management, multimedia streaming, backup solutions, virtualization, and containerized applications. There is even support of a 3rd Party App center that can be added in less than a minute to add even further applications and services to your Synology NAS system:

One of the standout features of DSM is its application center, known as the Synology Package Center. Here, users can find hundreds of first-party and third-party apps that can be easily installed to extend the functionality of their NAS. These apps cover a broad spectrum of use cases, including:

• Plex Media Server / Video Station (for now!) / Audio Station / Synology Photos for media streaming to smart TVs and mobile devices.
• Synology Active Backup for High-end license-free backup management across hundreds/thousands of devices
• Hyper Backup to manage domestic backup Operations
• The Office Collaboration Suite for an email manager, user chat facilities, office package and more
• Synology Container Manager / Docker for running containerized applications, which is essential for developers or businesses needing to test software in isolated environments.
• Virtual Machine Manager (VMM), allows users to run multiple operating systems, including Windows, Linux, and DSM Virtual Appliances, on a single NAS.

For businesses, Synology offers Active Backup for Business, a powerful backup solution that supports PCs, physical servers, virtual machines, and even cloud services like Office 365 and Google Workspace. This makes Synology DSM an attractive option for organizations looking for a comprehensive, multi-platform backup solution. DSM also excels in multimedia management. Apps like Synology Photos and Audio Station allow users to organize and access their photos, music, and videos from anywhere. Video Station, though recently phased out in favor of third-party options like Plex, has historically provided an easy-to-use platform for media streaming and management.

For surveillance needs, Synology offers Surveillance Station, which allows users to turn their NAS into a full-fledged NVR (Network Video Recorder), supporting IP cameras from a wide variety of manufacturers. This feature makes Synology NAS systems a compelling choice for businesses or homeowners who need both data storage and security monitoring.

While UniFi UNAS OS lacks the extensive feature set of DSM, it provides essential NAS features for file storage, snapshot management, and backup scheduling. It’s clear that UniFi’s focus is on simplicity and integration with their broader UniFi ecosystem. Drive is the primary app available on UNAS OS, offering basic file storage and sharing capabilities with snapshot and backup support.

Currently, UNAS OS does not support advanced features like Docker, virtual machines, or third-party media server apps such as Plex. This limits its appeal to more advanced users who need the ability to run multiple services or applications from their NAS. However, UniFi’s focus on network-level integration could be seen as a strength for businesses that already use UniFi networking hardware and want a NAS that fits seamlessly into their existing infrastructure.

There’s also potential for future growth. UniFi has a robust history of adding new features to their products post-launch, and it is possible that UNAS OS could see support for containerized applications like Docker or surveillance software such as UniFi Protect in the future. However, currently UniFi has not allowed Protect to be deployable on the UNAS Pro system – however you can use the UNAS Pro as a targetted storage system for your existing UNVR or UDM system. Most of the features of the UniFi UNAS Pro are not presented as ‘applications’ or ‘optional services’, but rather they are backed into the UX of the NAS OS already. Snapshots, Shared Drives, Security management, SMB file/folder management, Encrypted Drives, etc – all of it is in the OS already. That said, it still feels comparatively feature dry vs the Synology NAS pplatform.

I know I seem to be hammering the UniFi’s UNAS OS hard here, but currently it lacks many of the popular/current advanced capabilities that may appeal to users, favouring their simple and integrated experience over a large feature set.

Synology NAS H/W vs UniFi UNAS Pro – Hardware and Storage Expandability

Hardware and storage expandability is a critical factor for users looking to invest in a NAS system, especially for businesses or power users who expect their storage needs to grow over time. In this area, Synology excels, providing a broad range of options that allow users to easily expand their storage capacity and enhance system performance. On the other hand, UniFi’s UNAS Pro offers more limited expandability, focusing instead on offering a compact, all-in-one solution without much room for future upgrades.

Synology NAS systems are designed with scalability in mind. Many of their models, especially in the DS and RS series, allow for storage expansion via external expansion units. For example, the Synology DX517 expansion unit can add up to 5 additional drive bays to models like the DS920+, increasing the total number of drives and overall storage capacity. Similarly, Synology’s rackmount NAS solutions like the RS1221+ can connect to RX418 expansion units, enabling businesses to significantly increase their storage capacity as their data needs grow.

Additionally, Synology’s rackmount models often come with PCIe slots, allowing users to add features such as 10GbE networking, SSD caching, or even NVMe drives for high-speed storage pools. This level of hardware flexibility means that Synology systems can grow alongside a business’s needs, offering features that improve performance and expand storage without requiring a completely new system. For users seeking to maximize performance, Synology also offers support for SSD caching, which can greatly improve read and write speeds by using NVMe SSDs or SATA SSDs to cache frequently accessed data. Models like the DS1621xs+ support dual NVMe M.2 slots for SSD caching, giving users the ability to enhance performance even further without sacrificing drive bays for traditional hard drives.

Beyond the hardware expandability, Synology’s storage management features are equally powerful. Synology’s Hybrid RAID (SHR) technology allows users to mix and match drive sizes, making it easy to upgrade individual drives over time without losing data. SHR automatically optimizes storage space and provides RAID-like redundancy, ensuring data is protected even if drives fail.

In contrast, the UniFi UNAS Pro is designed as a more compact, self-contained unit. The 7-bay capacity offers a solid amount of storage from the outset, especially for SMBs and home users. However, the expandability options are much more limited when compared to Synology. For instance, the UNAS Pro does not support external expansion units, meaning that users are confined to the 7-bay configuration from the start.

Moreover, the UNAS Pro lacks PCIe slots or NVMe support, limiting its ability to be upgraded with features like 10GbE or SSD caching. This is particularly noticeable when comparing the UNAS Pro to Synology models that allow for these kinds of hardware upgrades. While 10GbE is included on the UNAS Pro, its lack of PCIe expandability means users cannot add additional features like dual 10GbE ports or SSD caching to further improve performance. Another limitation of the UNAS Pro is the inability to upgrade the RAM. While 8GB of DDR4 RAM is included, this cannot be expanded, which may be a limiting factor for users who want to run more intensive applications or serve multiple users simultaneously. In comparison, many of Synology’s NAS devices, such as the DS1821+, come with expandable memory, allowing users to increase RAM up to 32GB or more depending on the model.

Overall, UniFi’s UNAS Pro offers sufficient storage capacity for most small businesses and home users, but its lack of expandability makes it a less flexible solution for those who anticipate needing more storage or advanced features in the future.

Key Examples of Synology’s Expandable Hardware Features:

• DX517 Expansion Unit: Adds 5 additional bays to compatible DS series NAS devices.
• PCIe Slots: Found in models like the DS1621+, allowing for 10GbE upgrades, SSD caching, and more.
• NVMe Support: NVMe SSD caching is available in devices like the DS1621xs+, improving I/O performance.

HOWEVER, we also need to factor in that Synology has recently been reducing the number of 3rd party HDDs and SSDs that are listed as ‘compatible’ and ‘supported’ on their product advice pages. The majority of 2024/2025 systems now either list ONLY Synology HDD/SSD media (such as the HAT5300, SAT5210, SNV3410, etc) or list only a handful of storage media from established brands such as Seagate and WD (around 15-18 – out of potentially hundreds), despite them being proven to work successfully. UniFi has it’s own range of storage media drives for their UNAS Pro, UDM and UNVR systems, however they also widely support 3rd party drive utilities.

This would not be an issue in the case of Synology if their own branded storage media was the same price or superior – but the reality is that Synology storage media IS more expensive and in many cases a better, faster and/or larger drive from Seagate/WD is available at the same and/or lower price. This is less true on the entry NAS class of HDDs (eg Seagate Ironwolf vs Synology HAT3300, with only 2-4% difference), but once you look at higher capacity HDDs and more durable HDDs and SSDs, the price difference is kinda crazy:

Synology promotes their solutions are ‘all on one’ solutions and focus all their development towards a single NAS ecosystem, so focusing support, compatibility and operations towards their own media makes sense in a development sense. However, many first time Synology NAS buyers who are scaling up from smaller solutions or migrating away from SAAS/PAAS/Cloud storage in a big way might be unaware of the media storage policy they seem to be persuing. By no means a dealbreaker for many, but something to be aware of!

Synology vs UniFi ANS – Verdict and Conclusion

Choosing between Synology and UniFi NAS systems comes down to evaluating your specific needs, the level of software and hardware expandability you require, and whether you prioritize a more established ecosystem or tighter integration with your networking infrastructure. Both brands offer compelling NAS solutions, but they target different user bases and excel in distinct areas. For users who prioritize software features, scalability, and a broad range of applications, Synology is the clear winner. With over two decades of experience in the NAS market, Synology has fine-tuned its DSM (DiskStation Manager) software to offer an impressive array of first-party and third-party applications. Whether you’re a home user looking for a media server or a business seeking comprehensive backup solutions, Synology DSM provides an extensive feature set that meets almost any need. The rich support for virtualization, containerized apps, and backup tools makes it a top choice for advanced users and businesses with diverse requirements. Synology’s hardware lineup is also far more diverse, with options that cater to everyone from entry-level users to enterprises. Their hardware is expandable, supporting PCIe slots, NVMe caching, and external expansion units, which makes them suitable for users with growing storage needs or demanding performance requirements. Moreover, Synology’s Hybrid RAID (SHR) and flexible storage management tools are ideal for users who need to easily expand their storage without dealing with complex RAID setups. The downside of Synology, however, is its cost. While its hardware is packed with features, it comes at a higher price point, especially as you move up the product range. Additionally, some users have criticized Synology’s recent push to restrict third-party drive compatibility in newer models, which could be a drawback for users looking for more flexibility in their hardware choices.

UniFi’s UNAS Pro series is a newer player in the NAS field but leverages Ubiquiti’s expertise in networking to provide a product that is tightly integrated with the UniFi ecosystem. If you’re already invested in UniFi’s networking gear, adding a UniFi NAS to your setup can make network management and storage integration much simpler. UniFi’s controller-based system allows users to manage their entire network—including their NAS—from a single dashboard, which is a significant convenience for users in SMB environments. The UNAS OS, while still in its early stages, does an admirable job at nailing down the fundamentals of NAS functionality, such as file storage, snapshots, and backups. However, it currently lacks the depth and range of applications found in Synology DSM. This makes UniFi a better choice for users who are looking for simple storage solutions rather than advanced features like Docker, virtual machines, or third-party multimedia apps. When it comes to hardware expandability, UniFi lags behind Synology. The 7-bay UNAS Pro offers a decent starting point for storage, but the lack of PCIe slots, NVMe support, or external expansion units limits its long-term scalability. Furthermore, the inability to upgrade RAM or add additional 10GbE ports means that UniFi’s NAS might not grow as effectively with your needs over time. However, it does come with built-in 10GbE, which could be a compelling feature for users looking to take advantage of higher network speeds out of the box.

Which NAS Should You Choose?

• If you’re a business or power user who needs a highly customizable, feature-rich NAS with long-term expandability, Synology is likely the better choice. Its DSM software, extensive hardware options, and proven reliability make it a solid investment for users who want full control over their storage and the ability to run advanced applications.
• On the other hand, if you’re already embedded in the UniFi ecosystem and prioritize network integration over advanced NAS features, UniFi’s UNAS Pro may be more appealing. Its ease of use and seamless integration with other UniFi devices make it a great option for SMBs and users who prefer simplicity over extensive customization.

Ultimately, the decision between Synology and UniFi NAS depends on whether you value software flexibility and advanced applications (Synology) or seamless integration and simplicity (UniFi).
