UniFi New NAS Rumours – Everything We Know

Duing the UniFi World Conference event (the UWC 2025 expo event that took place in several places around the world over a week in May) the brand took the opportunity to share a huge amount of information about their roadmap for hardware and software in 2025 (and 2026!) and although there was a lot of information about cameras, switches, integrations and improvements – the big, BIG detail that emerged that got my attention was that the UNAS series of NAS devices is rumoured to be getting several portfolio additions over the course of the next 18+ Months! All of this was seemingly shared behind closed doors, with photography and video prohibited during the presentations (with choice projects by the brand like these limited to keynote ‘on stage’ presentations) and not available for general access and sharing on the show floor.

However, ALOT of the information shared was then discussed at length on forums and community sites across the internet (unsurprisingly predominantly on Reddit more than most – shocker I know). Because of this, we have a great deal of rumoured, shared and near-confirmed information about what the brand is planning for the soon to be growing UNAS series of devices – including a potentially dedicated M.2 NVMe SSD flash devices, Enterprise grade ZFS Rackmount system (XG NAS?) and even more entry level desktop solutions in 2 and 4 Bay SATA.

There is a lot to get to and I think we will likely see granular and gradual updates to all of these solutions as time wears on, so I wanted to create this article to add shared info and leaks as they appear online. You can get notifications and alerts on this page by subscribing at the bottom of the article.

IMPORTANT – Regardless of how solid/rumoured any of the UniFi UNAS systems that are detailed on this page are – do NOT be complacent about your data and backups! If you need a backup solution right now/soon, do not ‘hold out’ for these devices, as no device will ever be worth the danger of your data being lost (power lose resulting in a raid failure, data corruption, accidental deletion..need I go on?). So, if you like the sound of UniFi and their products, and the UNAS from UniFi sounds like it meets your needs, it is still available RIGHT NOW for just $499 HERE – It is a 7x SATA Half-Depth Rackmout NAS with 10GbE and a comprehensive data management software in UniFi Drive. You can watch my review HERE and my 6 Months Later update on it HERE.

Here is a list of Sources on Reddit that detail what was observed at Unifi World Conference 2025 with regard to Network Attached Storage:

Which UniFi UNAS Devices Are Rumoured for 2025 and 2026?

16th June 2025 Updated

Below are the details we know so far (some details need further verification and confirmation, indicated appropriately) that we are aware of so far. Keep in mind (IMPORTANT) that these drives are massively ‘TBC’, so alongside potential name changes it is also possible that they may not arrive at all – as UniFi might change their mind based on market research about the need for a given device! Additionally, sometimes information online is contradictory to other information (eg the larger and smaller scale NAS system and a potential Pro XG system might well be the same device!), so do not treat this information as set in stone! Let’s break down each entry:

>>>>> IMPORTANT – IMAGES FOR GUIDANCE ONLY <<<<<

2 Bay Entry-Level HDD NAS

The UNAS Pro, although popular, is none the less quite large for much smaller user deployments – so if UniFi was to really stretch it’s muscles into the world of NAS, it would come as no surprise that they would provide more entry/small-footprint devices. So, the oft mentioned 2 Bay UNAS would be desirable, but also UniFi’s most compact HDD system to date, targeting home and SOHO users looking for simple backup or file-sharing functionality. No confirmation or detail on the shared information on the hardware profile (one can imagine an ARM base and 2-4GB of memory – but it’s all very ‘TBC’) and 2.5GbE connectivity. 2 drives would give precious little bandwidth for 10GbE to even be worth the time of day, even with SATA SSDs.

An NVMe SSD NAS dedicated NAS for Creative Workflows

This proposed SSD focused NAS moves away from spinning disks in favor of M.2 NVMe SSD slots, focusing on silent, high-performance workflows for media creators or prosumers. This compact unit maintains a passive cooling design and leverages Drive 3.0’s new dynamic storage pool system to balance protection and performance. It’s intended for those needing faster I/O than HDDs can provide without the size or noise of a rackmount. if this ends up coming out, is would be INCREDIBLY popular (given M.2 SSD prices are now only around 2x more than HDD, with a 4TB M.2 NVMe SSD in both Gen3 and Gen4 hitting just $200+, and WD Red and Seagate Ironwolf 4TB HDDs around the $89-99 mark)

---

4 Bay Desktop-Grade HDD NAS

This would deliver a more durable 4-bay solution with a desktop form factor, designed for small business environments or tech-savvy users. It combines the flexibility of 3.5″ HDDs with the enhanced features of UniFi Drive 3.0, including smarter snapshots and storage pools. Compared to the standard UNAS 2-bay discussed solution, this model would offer better RAID options, as well as performance potential (even in a RAID 5). Nevertheless, if/when this comes around, expect modest hardware under the hood!.

A ‘Proper’ 4 Bay and 8 Bay Rackmount NAS

Alongside the already released 7 Bay UNAS Pro, there is talk of a 4 Bay and 8-bay rackmount NAS aimed at larger deployments such as offices, branch networks, or video surveillance environments as a storage target for UniFi Portect perhaps. Built to handle RAID 6 (rolling ut in the latest UniFi NAS OS and Drive updates) and large-scale storage pools, it includes business-class hardware for redundancy and expandability. Its release aligns with Ubiquiti’s push into more scalable data solutions under the UniFi Drive 3.0 future framework.

An Enterprise ZFS Appliance – THIS IS WHERE IT GETS GOOD!

Although the existing UNAS Pro NAS system runs on an BTRFS foundation, there was multiple references and rumours to UniFi’s first foray into ZFS-based NAS systems and appears to be targeted at enterprise environments requiring snapshot-based backup, inline compression, and greater control over storage topology. Very few hardware specifics have been shared, and it is unclear whether this is a completely separate physical unit or a software SKU atop a Pro-series device. I will be interested to see if, if this arrives, how they will migrate the existing UNAS/Drive/NAS OS appliances onto this ZFS base – as well as whether it will benefit from the inline and native performance/integrity benefits of ZFS!

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!
