UniFi UNAS – 1 Year Later. Should You Buy Now?

It has now been one full year since Ubiquiti made its formal debut in the NAS market with the launch of the UniFi UNAS Pro, a 7-bay rackmount storage system designed to integrate seamlessly within the existing UniFi ecosystem. At launch, the device was seen as a bold but limited step into a space traditionally dominated by established brands such as Synology and QNAP, focusing more on straightforward network storage than application-heavy server functions. Over the following twelve months, the company has steadily expanded the UNAS lineup and rolled out numerous firmware and software updates, refining its NAS operating system, UniFi Drive, and addressing user feedback gathered through real-world testing. From introducing multiple new RAID configurations, encryption, fan control, and USB backup capabilities, to expanding cloud backup support and improving system responsiveness, UniFi has demonstrated a consistent approach to building out the platform incrementally rather than replacing hardware prematurely. Today, the UNAS family includes five systems spanning both desktop and rackmount designs, with capacity options ranging from 2-bay PoE-powered units to 8-bay multi-10GbE solutions. Taken together, these changes illustrate a deliberate evolution of UniFi’s NAS portfolio from a proof of concept into a structured, multi-tier ecosystem with increasing competitiveness in the storage market.

Software Features Added/Improved in UniFi UNAS in 12 Months

In the twelve months since the release of the original UNAS Pro, UniFi Drive OS has developed from a relatively simple file server interface into a more complete NAS management platform. Early releases of the Drive software offered only basic storage creation and sharing options, limited to single-pool RAID 5 or mirror configurations with few administrative tools. Over time, multiple key features have been introduced, including support for RAID 6, multiple storage pools, clustered RAID pools, and hot spare functionality, each of which was implemented through system firmware updates and confirmed through beta and public release candidates. The platform now supports encrypted volumes, user-defined snapshots, and restoration features, offering greater resilience and improved recovery options after system events or accidental deletions. These updates collectively mark a notable improvement in fault tolerance and customization, allowing the UNAS range to better serve both small business and advanced home deployments that require multiple storage tiers or redundancy strategies.

Beyond storage structure, UniFi Drive has also introduced new tools for day-to-day administration and external connectivity. Cloud backup support has expanded to include Dropbox, OneDrive, and Google Drive, replacing the early limitation to only local or UNAS-to-UNAS replication. Shared drive management now includes central administrative oversight, allowing super admins to configure and monitor user-level backup routines across all profiles. The graphical interface itself has become more responsive, adding a file activity monitor that provides timeline-based access logs for folders and files. Support for Apple Time Machine has been added, as well as improved handling of executable files via SMB, and overall network protocol efficiency has increased through back-end adjustments to Samba and NFS. With these refinements, UniFi Drive OS now feels less like an experimental branch and more like a unified part of the broader UniFi management ecosystem, with greater parity across its networking, surveillance, and storage products.

Hardware Products Added/Improved in UniFi UNAS in 12 Months

Since the launch of the original UniFi UNAS Pro in late 2024, Ubiquiti has expanded the UNAS product line into a full hardware family, each model tailored for different deployment scales and power requirements. The first expansion arrived with the compact UNAS 2, a two-bay desktop NAS powered by PoE++, marking the brand’s first use of Power-over-Ethernet as a primary power source for network storage. This device, built around a quad-core ARM Cortex-A55 CPU and 4 GB of LPDDR4 memory, aimed to serve as a lightweight edge storage unit for small offices or UniFi network environments that rely on central power distribution. Its 2.5GbE connection and USB-C port (5 Gbps) provided moderate performance for local transfers and basic backup operations, while its non-hot-swappable dual-drive cage emphasized affordability over convenience. This smaller system demonstrated UniFi’s intent to create entry-level options that could still operate within their ecosystem while maintaining core integration with UniFi Drive OS and cloud management via ui.com.

The next step up in the product family is the UNAS 4, a four-bay desktop NAS that builds directly on the UNAS 2’s design but adds more flexibility. It retains the same ARM Cortex-A55 processor and 4 GB RAM, but introduces dual M.2 NVMe slots for SSD caching or storage expansion and four 3.5-inch SATA bays for larger arrays. It still uses 2.5GbE with PoE+++ as its main power and data input, though at the time of writing, UniFi has not confirmed if the final retail version will include a secondary Ethernet port for redundancy or faster link aggregation. This model brings the UniFi storage ecosystem closer to small business-level performance, allowing for RAID 6 redundancy and improved cooling through a refined chassis design. While compact, the inclusion of NVMe caching and full integration into UniFi Drive 3.3 makes it a practical choice for users who want local storage with minimal cabling and higher data throughput.

At the higher end, the UNAS Pro 4 and UNAS Pro 8 extend the lineup into the rackmount segment, reinforcing UniFi’s move toward professional and enterprise environments. The UNAS Pro 4 adopts a 1U form factor, supporting four 3.5-inch SATA drives and two M.2 NVMe slots, while maintaining the same ARM Cortex-A57 CPU and 16 GB LPDDR4 memory as its larger sibling. It also supports dual hot-swappable PSUs for redundancy and arrives with improved thermal airflow optimized for data center racks. The flagship UNAS Pro 8 offers eight 3.5-inch bays, two rear M.2 NVMe bays, and three 10GbE ports (one RJ45 and two SFP+), making it the highest-performing UniFi NAS to date. The system consumes up to 200W under load, uses Btrfs as the primary file system, and integrates the most comprehensive cooling and failover options in the UniFi NAS lineup. Together, these models illustrate UniFi’s full-tier hardware strategy: from PoE-powered desktop storage to rackmount systems supporting multi-gigabit networking and dual redundant power.

Fixes, Changes and Improvements in UniFi UNAS in 12 Months

Over the past year, UniFi has steadily refined the UNAS operating environment, addressing a number of software and usability issues identified by early adopters of the original UNAS Pro. Many of these improvements were released through incremental firmware updates across both the Drive OS and UniFi Controller platforms. Among the most significant early fixes was the resolution of file handling inconsistencies between the built-in web file manager and SMB-based network access, which previously caused discrepancies when deleting or restoring data.

This issue, which affected synchronization between the NAS GUI and mapped network shares, has now been corrected. Similarly, early memory leak and permission errors during large-scale SMB transfers have been resolved through back-end optimization, reducing skipped files and improving overall data reliability. Updates to the system logs and storage integrity checks also brought clearer reporting of failed transfers and RAID rebuild activity, ensuring that users now receive consistent system notifications and warnings.

Another key focus for UniFi’s development team over the last twelve months has been user management, network integration, and environmental control. Earlier versions of Drive OS restricted backup operations to individual users, preventing the super admin from managing backups or schedules across the system. This has since been rectified, allowing full central backup management, while user permission hierarchies have been expanded to distinguish between local-only accounts, remote accounts, and enterprise identity-linked users.

Environmental improvements include the long-requested fan control interface, which gives users the option to manually adjust fan speeds or keep automatic control active depending on temperature thresholds. The addition of real-time thermal monitoring, more accurate CPU and drive temperature reporting, and improved resource graphs now make it easier to track system health. The Drive 3.3 release also introduced a refined GUI with more responsive dashboard elements, consistent data updates in the system console, and a correction to the long-standing uptime reporting bug that falsely displayed “20,000 days active.”

Missing Features and Planned Features in UniFi UNAS in the Next 12 Months

Despite significant progress since the launch of the original UNAS Pro, several key features are still missing from the UniFi Drive OS ecosystem. The most frequently requested addition from users continues to be iSCSI target and initiator support, a capability that would allow direct block-level storage mapping for virtual machines and professional applications. Its absence limits the UNAS series to traditional network file protocols such as SMB and NFS, which are less efficient for tasks requiring raw storage access or integration with virtualization platforms. Equally, the continued lack of RAID 0 support restricts high-performance users who are willing to trade redundancy for speed. While RAID 6 and clustered pools have been introduced, there is still no configuration option that prioritizes sequential throughput over redundancy. Another omission is a native UniFi Drive client tool for Windows, macOS, or Linux that would allow direct desktop synchronization, local file pinning, and on-demand streaming similar to Synology Drive or Dropbox. At present, users must rely on the web interface or manually mapped drives, which limits productivity and offline access.

Looking forward, UniFi has hinted through developer notes and recent firmware structure that the ENAS (Enterprise NAS) line will introduce ZFS file system support, marking a major shift toward high-end storage with data integrity and snapshot efficiency beyond Btrfs. This aligns with the observed trend of UniFi testing ZFS integration within their enterprise roadmap, possibly extending limited functionality to future revisions of the Pro 4 and Pro 8. The upcoming UniFi Drive 3.3 and 3.4 updates are also expected to expand fan and power scheduling, allowing users to define specific system on/off cycles and control Ethernet port activation schedules, effectively creating customizable air-gap routines. Additionally, UniFi’s roadmap includes exploring expansion connectivity, potentially leveraging unused 10GbE interfaces for network-based expansion enclosures or storage clustering between UNAS units. This would mirror the high-availability (HA) or expansion behavior of established NAS brands, though implemented entirely over the UniFi network layer.

UniFi is also expected to refine NVMe handling, particularly the ability to use installed M.2 drives as standalone storage pools rather than just as cache devices. The introduction of pool-level tiering and dynamic storage balancing could allow users to automatically assign workloads between SSD and HDD pools, improving I/O efficiency without manual adjustment. Beyond hardware-level improvements, there is ongoing demand for the integration of UniFi Protect within the NAS family, allowing video surveillance to run on the same physical storage units rather than on separate NVRs. Although UniFi has historically separated its Protect and Drive ecosystems, internal hardware similarities between the UNAS Pro and UNVR Pro systems suggest eventual compatibility is possible. Finally, more advanced backup filters, bandwidth scheduling, and automated snapshot policies are likely to appear in the next major OS iteration as part of UniFi’s effort to close the gap with traditional NAS brands while maintaining its minimalist network-first design approach.

Conclusion and Verdict – Is the UniFi UNAS Good Now?

One year after the launch of the original UniFi UNAS Pro, the UniFi NAS platform has evolved from a single experimental product into a diversified ecosystem that spans both desktop and rackmount storage. The introduction of the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8 demonstrates that Ubiquiti is committed to building a scalable product range capable of serving both home users and small business environments. On the software side, the development of UniFi Drive OS has been steady and deliberate, with a focus on improving reliability, expanding RAID options, and tightening cloud and local backup integration. These changes, combined with improved temperature management, admin-level control, and performance tuning for SMB and NFS, have resulted in a more mature and dependable NAS experience than the early versions from 2024. However, the range remains deliberately streamlined, prioritizing simplicity and ecosystem integration over third-party app support or virtualization features.

Looking ahead, the next phase of the UniFi NAS roadmap appears to focus on deeper enterprise integration and feature parity with long-standing NAS brands. The likely addition of iSCSI, ZFS, and network-based expansion options will determine how far UniFi can move beyond entry and mid-range use cases. The hardware continues to rely on ARM processors rather than x86, which reinforces UniFi’s focus on efficiency and security but limits advanced workloads such as containerization and VM hosting. Even so, the value proposition remains strong, particularly given the aggressive pricing across the entire UNAS range and its seamless compatibility with the existing UniFi infrastructure. Overall, UniFi’s NAS systems are no longer a novelty—they represent a serious and rapidly developing branch of the company’s portfolio that has gained stability, utility, and confidence within just one year.

UGREEN NASync vs UniFi UNAS – Which Should You Buy?

In the evolving landscape of network-attached storage, the arrival of UGREEN and UniFi (Ubiquiti) marks one of the more interesting shifts in consumer and prosumer data management over the last two years. Both brands, previously recognised for their strength in peripheral hardware and networking respectively, officially entered the NAS sector around late 2023 to early 2024, each taking distinct approaches to design, functionality, and ecosystem integration. UGREEN, following a successful crowdfunding launch in early 2024, built its NASync series around desktop and SSD-based solutions for home, creative, and prosumer users seeking all-in-one local storage, virtualization, and multimedia platforms. Its portfolio now includes systems ranging from the ARM-based DXP2800 to the Intel-powered DXP8800 Plus, offering performance tiers from modest home use to compact workstation-class environments.

Meanwhile, UniFi, a brand with a long history in professional networking and surveillance infrastructure, released its UNAS family within the same timeframe, targeting users already invested in its ecosystem of routers, cameras, and switches. The UNAS lineup now spans from the compact UNAS 2 and UNAS 4 desktop units to the rackmount UNAS Pro 4 and Pro 8 systems, with each designed for straightforward deployment and remote integration within the UniFi Network and Protect platforms. Despite arriving from very different sectors, both companies have effectively lowered the cost of entry to reliable NAS storage while redefining how integrated ecosystems can extend storage functionality. This comparison explores their respective design choices, hardware capabilities, software environments, and operational scope to assess which platform is best suited to different user scenarios in 2025 and 2026.

UniFi vs UGREEN NAS – The TL;DR

In comparing the UniFi and UGREEN NAS platforms, it becomes clear that each brand represents a different vision of what modern network storage should be. UniFi’s UNAS series builds on the company’s heritage in networking and surveillance, delivering a range of efficient, ARM-powered NAS systems that integrate tightly within the UniFi ecosystem. Models such as the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8 prioritize reliability, centralized management, and long-term stability rather than raw compute power or expandability. Their hardware is deliberately fixed—non-upgradable memory, ARM Cortex-A55 or A57 CPUs, and limited caching support for NVMe drives—but balanced by advanced network connectivity, including dual 10G SFP+ ports, PoE+++ power options, and redundant power supplies. UniFi’s storage OS focuses on core NAS fundamentals: multiple RAID levels, snapshots, encryption, and secure remote access via the UniFi controller. It is intentionally simple, relying on integration with other UniFi products for extended functionality such as surveillance and automation. In contrast, UGREEN’s NASync line follows an open, performance-driven approach designed for flexibility and standalone capability.

Ranging from the DXP2800 with its 8-core ARM processor to the flagship DXP8800 Plus powered by Intel’s i5-1240P, these systems cover every segment from entry-level home use to prosumer and light enterprise workloads.

UniFi vs UGREEN NAS – Design, Storage and Range

When comparing UGREEN and UniFi’s NAS portfolios, the first and most visible difference lies in how each brand approaches system design and deployment environment. UGREEN’s NASync series is focused entirely on desktop enclosures, reflecting the brand’s consumer electronics background and intent to cater primarily to home users, prosumers, and creative professionals. Each model, such as the DXP2800, DXP4800 Plus, and DXP8800 Plus, follows a compact, upright chassis layout with attention to quiet cooling and minimal footprint. The aesthetic is consistent across the range—metallic finishes, clear drive bay accessibility, and understated branding—intended to fit easily on a desk or in a studio environment. By contrast, UniFi’s UNAS range adopts both desktop and rackmount designs, depending on model class. The UNAS 2 and UNAS 4 are designed for smaller workspaces and integrate PoE+++ power options to simplify installation, while the UNAS Pro 4 (1U) and UNAS Pro 8 (2U) are full rackmount systems made from SGCC steel, reflecting their professional and data-center-friendly construction standards.

UGREEN’s systems emphasize flexibility and user-level expandability within their desktop footprint. Most models in the NASync line support 2.5-inch or 3.5-inch SATA drives, dual NVMe SSD slots, and optional PCIe or Thunderbolt expansion, allowing them to function as both storage servers and active editing platforms. The DXP480T Plus, for example, is an all-SSD NAS with four M.2 NVMe bays that appeals to users seeking maximum I/O performance for tasks such as 4K video editing or database caching. The DXP8800 Plus, the flagship, extends this design language with eight SATA bays, dual Gen 4 M.2 SSD slots, dual 10 GbE networking, and Thunderbolt 4 connectivity, making it one of the most powerful turnkey NAS options in the consumer space. In comparison, UniFi’s UNAS systems prioritize structural consistency and network integration over expandability. Even though all models provide dual or single NVMe slots, these are limited to caching duties. Drive capacity across the lineup scales more linearly, from two to eight 3.5-inch bays, maintaining a clear size-to-performance progression while focusing on rack density and cooling efficiency.

From a usability perspective, UGREEN’s design philosophy focuses on standalone versatility. Each NASync model is built to function independently as a complete storage and application host, with optional integration through standard network protocols. Physical accessibility is a clear design consideration, with quick-release trays, front USB ports, and in some models, SD card readers for direct media offload. The visual and acoustic design is optimized for open environments, with whisper-quiet fan systems and smart temperature management, making them suitable for use beside workstations or in living spaces. UniFi’s design philosophy, however, centers on infrastructure harmony rather than isolation. The rackmount models are designed to slide directly into existing UniFi network installations, using standard 1U or 2U spacing and consistent power integration with UniFi’s USP-RPS redundant supply network. Even the desktop UNAS 4 maintains visual continuity with UniFi routers and switches, using similar matte finishes, front-facing status LEDs, and clean ventilation lines.

In terms of product range, UGREEN currently offers at least seven NASync models, each targeting a specific performance segment. These include the DXP2800 (2-bay ARM), DXP4800 (4-bay N100), DXP4800 Plus (4-bay N305), DXP6800 Pro (6-bay N305), DXP480T Plus (SSD-only, N305), DH4300 Plus (4-bay ARM), and DXP8800 Plus (8-bay i5-1240P). Each generation introduces more advanced CPUs, faster interfaces, and expanded media capabilities. UniFi’s current UNAS range, while smaller, has diversified rapidly since its launch. The confirmed models include the UNAS 2, UNAS 4, UNAS Pro 4, UNAS Pro 8, and the earlier UNAS Pro 7-Bay, all of which use ARM-based processors and fixed memory configurations. A larger ENAS 16-Bay ZFS system is already in development, targeting enterprise and datacenter deployments in 2026. Compared with UGREEN’s more gradual tiered approach, UniFi’s product scaling is defined by form factor and network bandwidth rather than by CPU class or user workload.

Price segmentation further highlights their opposing strategies. UniFi’s UNAS line is priced aggressively to attract users into its broader ecosystem, starting at $199 for the UNAS 2, rising to $799 for the Pro 8, and including mid-tier models like the UNAS 4 ($379) and Pro 4 ($499). The pricing aligns with UniFi’s established model of offering capable hardware at low margins to encourage ecosystem investment across switches, cameras, and controllers. UGREEN, by contrast, positions its NASync devices as feature-rich all-rounders, with prices reflecting performance class: from $279 for the DXP2800 to around $1,299 for the DXP8800 Plus. The difference in pricing structure is significant but reflects how each company defines value—UniFi through integrated ecosystem scaling, and UGREEN through standalone hardware strength and included functionality.

 

UniFi vs UGREEN NAS – Hardware Range

The internal hardware philosophy of UniFi and UGREEN reflects two distinct interpretations of what a modern NAS should prioritize: efficiency and integration versus performance and versatility. UniFi’s UNAS series relies entirely on ARM-based architecture, a deliberate decision aligned with the company’s emphasis on low power consumption, predictable thermal characteristics, and embedded system reliability. Every model in the current UNAS lineup, including the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8, is built around a quad-core ARM processor—the A55 at 1.7 GHz for the smaller systems and the A57 at 2.0 GHz for the rackmount models. These CPUs deliver modest compute performance but strong stability and power efficiency, allowing for sustained 24/7 operation without requiring active thermal management beyond standard fan arrays. This design philosophy mirrors UniFi’s broader network device ecosystem, where embedded ARM SoCs dominate routers, gateways, and cameras, ensuring unified firmware management and hardware compatibility across all product categories.

UGREEN’s NASync architecture takes the opposite route, aiming to deliver workstation-grade power in compact form factors. The entry-level DXP2800 features an octa-core ARM CPU, already outpacing UniFi’s top models in raw processing capability, while the remainder of the series transitions to x86 platforms from Intel’s latest low-power and mid-tier lines. The DXP4800 uses Intel’s N100 processor, the DXP4800 Plus and DXP6800 Pro adopt the more capable N305 with improved iGPU performance, and the flagship DXP8800 Plus integrates the 12th Gen Intel Core i5-1240P, offering hybrid performance and support for hardware transcoding, virtualization, and PCIe Gen 4 NVMe. This variation in processor choice underlines UGREEN’s strategy of providing scalable compute resources for different workloads, from basic backup operations to multi-user virtualization and AI-assisted indexing. Unlike UniFi, UGREEN’s systems can operate as full Linux servers, running multiple containers or virtual machines without external dependencies.

Memory and expansion options further highlight the divergence in hardware scope. UniFi’s systems employ fixed memory configurations—ranging from 4 GB on the UNAS 2 and 4 to 16 GB on the Pro 8—with no user-accessible upgrade paths. This aligns with their embedded design approach, where firmware optimization and unified memory management are prioritized over modularity. In contrast, UGREEN’s NASync devices all support user-upgradable SO-DIMM DDR4 or DDR5 modules, typically allowing capacities between 8 GB and 64 GB, depending on the model. This flexibility benefits users running memory-intensive services such as Docker containers, Plex transcoding, or AI indexing. Moreover, many of UGREEN’s x86 systems support PCIe expansion cards, offering pathways to add 10 GbE NICs, NVMe storage adapters, or GPU accelerators, while UniFi’s systems are intentionally non-upgradable to maintain uniform hardware control and firmware consistency across the UNAS ecosystem.

Networking and connectivity options serve as another key point of differentiation. UniFi has leaned on its networking pedigree, offering up to three 10 GbE connections (two SFP+ and one RJ45) on the UNAS Pro 8, with lower-tier models still providing 2.5 GbE or Gigabit connectivity. Power integration is also a hallmark of their design. The UNAS 2 and UNAS 4 use PoE+++, allowing single-cable deployment through UniFi switches, while the Pro series employs redundant power via USP-RPS or hot-swappable PSUs, reducing downtime in managed networks. UGREEN, on the other hand, focuses on local performance flexibility, providing multi-interface options like 10 GbE, 2.5 GbE, USB 4, and Thunderbolt 4, depending on model class. This allows their systems to double as direct-attached storage (DAS) for editors or content creators, particularly when used via Thunderbolt, an option not present in any UniFi NAS. Power designs in UGREEN systems are conventional but efficient, ranging from compact external adapters on smaller models to integrated supplies on higher-end devices.

The overall hardware comparison reveals two clear user archetypes. UniFi’s hardware suits IT administrators and network professionals seeking dependable, uniform, low-maintenance appliances that integrate natively with UniFi controllers and services. UGREEN’s NASync hardware, meanwhile, targets prosumers, creative professionals, and small business users requiring computational headroom and direct system control. Where UniFi builds closed but predictable infrastructure devices, UGREEN delivers open and adaptable machines capable of serving as both NAS and lightweight servers. The contrast is not one of quality but of philosophy—UniFi favoring consistency and system management efficiency, UGREEN focusing on flexibility and computational breadth.

UniFi vs UGREEN NAS – Software, Services and Apps

The most significant distinction between UGREEN and UniFi’s NAS platforms lies in their software ecosystems and the broader intent behind their development. UniFi’s UNAS software mirrors the brand’s overarching approach to product design: lightweight, efficient, and designed to integrate seamlessly into the UniFi Network and Protect ecosystems. The UNAS interface focuses almost exclusively on storage management and file security. It provides the fundamental NAS feature set, including multiple RAID configurations, volume encryption, snapshot management, and user-based permission control. Files can be accessed through SMB, NFS, with remote management possible via the UniFi portal or mobile app. However, beyond core storage functionality, UniFi’s NAS software remains deliberately minimal. It lacks support for virtual machines, Docker containers, or app installation frameworks, relying instead on integration with other UniFi devices for broader capabilities such as video surveillance, network management, or cloud relay services.

UGREEN’s UGOS Pro platform adopts a far more expansive, multifunctional design. The software is built on a modern Linux kernel and supports both ARM and x86 architectures, allowing for a full-featured environment with native support for containers, virtual machines, and AI-enhanced media indexing. Out of the box, users can deploy Docker, Portainer, Kubernetes-compatible containers, and KVM-based virtual machines, enabling workloads that go far beyond traditional NAS operations. Backup and synchronization options are also more diverse, with support for rsync, S3, WebDAV, iSCSI, OneDrive, Google Drive, Dropbox, and two-way synchronization across multiple NAS units. The interface emphasizes transparency and customization, giving users direct access to system-level configuration that UniFi’s more streamlined interface omits. Features such as storage tiering (using both HDD and NVMe), application sandboxing, and external GPU detection on select models position UGREEN’s UGOS Pro as one of the most open and flexible NAS operating systems currently available outside of enterprise-class environments.

In client and access support, the contrast continues. UniFi’s ecosystem is designed for centralized control and consistent performance across its product range. The UNAS systems can be monitored via the same UniFi Controller interface used for switches, gateways, and access points, creating a single-pane-of-glass environment that appeals to IT administrators managing multiple UniFi sites. Remote access and firmware updates are handled automatically through UniFi Cloud, and security is strengthened by integration with two-factor authentication, device certificates, and network isolation policies inherited from the company’s professional networking hardware. UGREEN, conversely, provides a more conventional NAS interface that supports multiple access clients and cross-platform tools. In addition to browser access and mobile apps for Android and iOS, users can mount shared drives directly within macOS, Windows, and Linux, while also leveraging a dedicated UGREEN Drive application for photo management and AI-based face/object recognition. Where UniFi’s UNAS feels like an extension of a larger network ecosystem, UGREEN’s software operates as a complete standalone server environment.

Security and maintenance are handled very differently between the two brands. UniFi benefits from a mature background in network device hardening, employing signed firmware, rolling updates, and extensive beta testing through its large enterprise user base. Features such as encrypted storage volumes, HTTPS enforcement, and VLAN isolation come preconfigured with minimal user intervention. However, the trade-off for this controlled environment is reduced user autonomy, as firmware customization and software-side experimentation are discouraged. UGREEN, while newer to the enterprise security space, implements encryption standards such as AES-256, offers built-in 2FA, and continues to expand its ransomware prevention and snapshot recovery tools. Updates arrive frequently and often include feature additions alongside security patches, though the brand still lacks a formal bug bounty or transparency reporting system comparable to UniFi’s. Overall, UGREEN’s software offers greater flexibility and control, while UniFi’s remains more mature and hardened within its controlled network framework.

 

UniFi vs UGREEN NAS – Verdict and Conclusion

Both UGREEN and UniFi have entered the NAS sector from distinct starting points and continue to move in different directions, each targeting a particular type of user. UniFi’s UNAS series delivers consistency, predictable performance, and dependable integration with the broader UniFi ecosystem. Its software is stable, lightweight, and well-suited to users who prioritize straightforward storage management, reliable data handling, and unified control across routers, switches, and surveillance systems. While the hardware is limited to fixed ARM configurations and non-expandable memory, it is efficient, quiet, and designed for continuous operation with minimal maintenance. For organizations already invested in UniFi infrastructure, the UNAS systems provide a logical expansion that keeps management centralized and operational risk low. However, their value depends heavily on ecosystem synergy; outside of that environment, the systems remain competent but relatively inflexible standalone NAS options.

UGREEN’s NASync platform, on the other hand, appeals to users seeking broader performance capability and independence. Its x86-based models, upgradable memory, and open software environment allow it to serve as a hybrid between NAS and compact server, capable of running applications, containers, and virtual machines alongside storage tasks. The design language is more suited to individual or small business use than datacenter deployment, but the hardware range—from ARM to Core i5—covers a far wider performance spectrum than UniFi’s. Software maturity continues to evolve quickly, with new features added frequently, and the systems provide extensive compatibility with third-party clients and backup services. The trade-off is that long-term reliability and enterprise-level security validation are still developing.

Ultimately, UniFi NAS suits users who already rely on UniFi’s networking ecosystem and value simplicity, predictability, and centralized management, while UGREEN NAS caters to those prioritizing flexibility, compute power, and open software capability. Both brands have lowered the entry barrier into reliable NAS ownership, but they embody opposing philosophies: UniFi focuses on integration and control, whereas UGREEN emphasizes capability and independence.

UniFi MASSIVELY Scale up their NAS Portfolio with the UNAS Pro 8, UNAS Pro 4, UNAS 4 and UNAS 2

Note, the UNAS Pro 2 is NOW LIVE on the UniFi Store . The UNAS 4, UNAS Pro 4 and UNAS Pro 8 are now in the site, but are not available till October.

Ubiquiti is preparing to significantly broaden its NAS product line in late 2025 with the introduction of four new systems under the UNAS branding. The new lineup follows the launch of the original UNAS Pro in 2024, which gained attention as a low-cost, seven-bay rackmount appliance that introduced UniFi into the NAS sector. With the release of the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8, the company is moving into what it describes as its “phase two” of NAS development, aiming to cover both desktop and rackmount form factors while integrating closely with the wider UniFi ecosystem. This expansion arrives at a time when established NAS vendors are tightening drive compatibility and raising prices, leaving a gap for alternatives that emphasise affordability, simplified deployment, and ecosystem consistency.

The UNAS Pro 8 NAS

4-Core ARM, 16GB RAM, 3x 10GbE, 8x SATA Bays, 2x M.2 Bays (trays required), Redundant PSU (2nd Sold Seperately) $799 – HERE

The UNAS Pro 8 will serve as the top-end model of the range, positioned in a 2U rackmount chassis and built to deliver higher capacity and redundancy. It features eight front-facing 2.5″/3.5″ SATA bays alongside two rear-mounted M.2 NVMe slots, accessible through modular trays.

The Pro 8 is powered by a quad-core ARM Cortex-A57 processor running at 1.7 GHz and paired with 16 GB of LPDDR4 memory. Unlike many entry-level ARM systems, the Pro 8 includes three 10-gigabit network interfaces: two SFP+ and one RJ45 supporting multi-gig speeds down to 100 MbE. Redundant hot-swappable 550W PSUs are supported, though only one is included by default, with seamless failover tested successfully under load.

The UNAS 2 runs on a quad-core ARM Cortex-A55 at 1.7 GHz with 4 GB of LPDDR4 memory. Networking is provided by a single 2.5 GbE RJ45 port, which also delivers PoE++ power, with a maximum system budget of 60W (52W for drives). A 60W PoE++ injector is included for users without a suitable switch. A 1.47-inch colour LCM display on the front provides status updates, though it is non-interactive. A USB-C port rated at 5 Gbps adds external storage capability, addressing an omission noted in the original UNAS Pro, but it does not support UPS integration or networking adapters.

The UNAS Pro 4 NAS

4-Core ARM, 16GB RAM, 10GbE, 4x SATA Bays, 2x M.2 Bays (trays required), Redundant PSU (2nd Sold Seperately) $499 – HERE

Between these two extremes sits the UNAS Pro 4, a 1U rackmount unit designed for users who want the resilience of redundant PSUs and NVMe support without committing to an eight-bay chassis.

It includes four SATA bays and two M.2 NVMe slots, sharing the same ARM Cortex-A57 CPU and 16 GB of memory as the Pro 8. Like its larger counterpart, it is built for rack environments where redundancy and compact form factor are key priorities.

While exact dimensions and weight have not yet been confirmed (with the UNAS 2 and UNAS Pro 8 being the main focus of this new launch), the design is expected to follow Ubiquiti’s established rackmount conventions. Its specification profile makes it an option for smaller businesses or branch offices that need rack integration but do not require the capacity of an eight-bay system.

Category	Specification

4-Core ARM, 4GB RAM, 1X 2.5GbE PoE+++ (TBC), 4x SATA Bays, 2x M.2 Bays (trays required), Power Over Ethernet delivery (PoE+++ Adapter Included) $379 – HERE

The UNAS 4, meanwhile, extends the desktop line and mirrors the design philosophy of the UNAS 2 but doubles the bay count.

It provides four 3.5″ SATA bays along with two M.2 slots, making it the only desktop model in the range to support NVMe caching or tiered storage.

It retains the same ARM Cortex-A55 CPU and 4 GB of fixed memory as the UNAS 2, positioning it as a modest but slightly more versatile desktop option.

Like the smaller model, it uses PoE+++ for power delivery and 2.5 GbE for connectivity, though it remains unconfirmed whether it will also include a secondary network interface for failover or link aggregation. As with other desktop models, the chassis is constructed from polycarbonate, with compact dimensions intended for office or home use rather than data centre deployment.

Category	Specification
Form Factor	Desktop NAS

UniFi Drive 3.3 Update?

Alongside the hardware announcements, UniFi will also release UniFi Drive 3.3, a major update to its NAS management software.

This version introduces expanded RAID configuration options, broader support for third-party cloud platforms, enhanced fan control, and improved analytical tools for monitoring system health and performance.

Snapshots and backups remain central features, with cloud and LAN targets supported, while the update also improves scheduling flexibility and introduces additional reporting features.

Although iSCSI remains absent, UniFi Drive continues to mature from the limited platform released with the first UNAS Pro, and the 3.3 update is expected to improve usability across the entire new range.

The introduction of these four models demonstrates Ubiquiti’s intent to build a full family of NAS solutions rather than rely on a single experimental release. By offering both rackmount and desktop systems at varying capacities, the company is positioning itself to compete more directly with established NAS vendors, albeit with a more streamlined and ecosystem-focused approach. The UNAS 2 and UNAS 4 are targeted primarily at existing UniFi users seeking simple storage that integrates seamlessly with PoE switches, while the Pro 4 and Pro 8 are built to appeal to businesses looking for redundancy, higher bay counts, and greater throughput. The use of ARM processors across the line reflects UniFi’s efficiency-first design, even though it places limits on heavy workloads such as virtualisation or multimedia transcoding.

Detailed performance reviews and comparisons of the new models are expected in the weeks ahead, assessing how each device performs within its target segment. Particular attention will focus on how the Pro units handle sustained 10GbE workloads with HDD and SSD configurations, how the PoE-driven desktop models cope with thermal and power constraints, and how UniFi Drive 3.3 stacks up against more mature operating systems. With Ubiquiti steadily fleshing out its NAS portfolio one year on from the first UNAS Pro, the company’s ability to deliver consistent updates and address early hardware and software limitations will determine whether it can establish a lasting position in the NAS market.
