NEW UniFi NAS – What Comes Next in 2025/2026? ZFS, NVMe, More Racks
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.

|---|---|
| Specification | Details |
| Bays | 2 x 3.5” HDD |
| Storage Type | SATA HDD |

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)
|
|
|---|---|
| Specification | Details |
| Bays | Unknown – Possibly 4x M.2 NVMe |
| Storage Type | PCIe SSD (M.2) |
| Software | UniFi Drive 3.0 (NVMe pool optimization) |
| Features | High-performance SSD storage, silent design |
| Status | Confirmed Seen at UWC 2025 |
| Source(s) | Source 1, Source 3 |
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!.

|---|---|
| Specification | Details |
| Bays | 4 x 3.5” HDD |
| Storage Type | SATA HDD |
| Cooling | Active fan (almost certainly!) |
| Software | UniFi Drive 3.0 |
| Features | Mid-range performance, desktop NAS |
| Status | Confirmed Seen at UWC 2025 |

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.

|---|---|
| Specification | Details |
| Bays | 4 and 8 x 3.5” HDD |
| Storage Type | SATA HDD |

| Status | Confirmed, Seen at UWC 2025 |

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!
|
|
|---|---|
| Specification | Details |
| Bays | TBD |
| Storage Type | ZFS pools (likely mixed HDD/SSD) |
| Cooling | Likely 2 stage rackmount active cooling |
| Software | ZFS OS (Unconfirmed re:UniFi Drive 3.0) |
| Features | Snapshots, compression, enterprise storage, in-line ZFS benefits |
| Status | Confirmed (via software roadmap) at UWC 2025 |
| Source(s) | Source 3, Source 4 |
