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 system uses SGCC steel for the enclosure, weighs 11.5 kg, and includes rack rails in the box, a detail rarely seen in turnkey solutions. Performance tests have demonstrated sequential reads close to 850 MB/s on HDDs in RAID 5, with expectations of saturating a 10GbE link when using SSDs or RAID 0.

The UNAS 2 NAS

4-Core ARM, 4GB RAM, 1X 2.5GbE PoE+++, 2x SATA Bays, Power Over Ethernet delivery (PoE+++ Adapter Included) $199 – HERE

At the opposite end of the spectrum is the UNAS 2, UniFi’s smallest NAS to date. This desktop unit measures just 13.5 x 12.9 x 22.37 cm and weighs 1.3 kg, with a polycarbonate chassis designed to keep cost and weight down.

The device supports two 3.5″ SATA drives housed in a shared tray, a design that requires both drives to be removed together and does not permit hot-swapping. This approach raises concerns about handling healthy drives during replacement but reduces the mechanical complexity of the system.

Category Specification
Form Factor Desktop NAS
Dimensions 135 x 129 x 223.7 mm (13.5 x 12.9 x 22.37 cm)

Thermal Range CPU ~75–80°C under stress, 50–60°C idle/light use
Management UniFi OS web interface, Ethernet, Bluetooth 4.1 for setup
Certifications FCC, CE, IC; NDAA Compliant

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
Form Factor Rackmount NAS (1U)
Drive Bays 4 x 2.5″/3.5″ SATA HDD/SSD
M.2 Support 2 x M.2 NVMe slots
RAID Support RAID 0, 1, 5, 6, clustered RAID, Single Disk
Hot Swap Supported
CPU Quad-Core ARM Cortex-A57, 1.7 GHz
Memory 16 GB LPDDR4 (non-upgradeable)

Management UniFi OS web interface; Ethernet, Bluetooth 4.1 for setup
Positioning Compact 1U rackmount, same CPU/RAM as Pro 8, with redundancy support

The UNAS 4 NAS

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
Enclosure Material Polycarbonate
Drive Bays 4 x 3.5″ SATA HDD
M.2 Support 2 x M.2 NVMe slots (for caching/tiered storage)

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.

      1. The single PoE port is a risk imho for an abrupt shutdown if you update or restart the switch and don’t use the adapter.. I wonder if they are considering that in their software.. Does a grace shutdown option exists?

      5. Seems a perfect replacement for the old Apple AirPort Time Capsule!

        Perfect timing as Apple are discontinuing support for Time Capsule in macOS27. And Apple Time Machine backups are already encrypted so the lack of disk encryption isn’t an issue luckily.

      33. Thanks for the review! I like their thinking with their NAS devices being for storage only. Mini PCs are so cheap now that anybody looking to do enthusiast level stuff with their NAS is better served by a low price NAS + MiniPC vs a high priced all in one device.

        I do think they are missing some key storage functionality from this though – especially for me, I would want some kind of cloud sync to “reverse backup” my Google Drive etc onto the NAS in case I lose access to my Google account. And encrypted backups? I didn’t see an option to encrypt the backup in the backup task creation screen.

        Hopefully they can add some of these things soonish.

      49. I heard about these coming about a month and a half ago. Was at a Unifi event LAST WEEK! They didn’t have these there even, but they mentioned that a desktop 4 bay was coming. Now then they are in the store we can discuss them.

        The 4 bay with m.2, is SSD only used for caching or can you have tiered storage pools?

      61. Very much looking forward to the 8 bay pro model with 2 caching drives. That needs iSCSI. I am unsure on the UNAS Pro (existing model) due to 7 bays. But 8 bays with caching drives, for a bit more $, will be a great simple NAS to back up to and use to store VM snapshots and software installers, backup of NVRs. Now here’s hoping the local importers put this on their pricelists, as I can’t buy from the US (the UI store just cancels orders to freight forwarders these days)

      63. Very much looking forward to the 8 bay pro model with 2 caching drives. That needs iSCSI. I am unsure on the UNAS Pro (existing model) due to 7 bays. But 8 bays with caching drives, for a bit more $, will be a great simple NAS to back up to and use to store VM snapshots and software installers, backup of NVRs.

      66. They just need to update the CPU so we can run containers and it’s a done deal. Many turn key solutions, Qnap & Synology, already support this so it’s strange that this is pure purpose built.

      68. Imagine Synology 225+ is just around 280,-USD with zillions applications, docker and mainly Active Backup – the most important piece of software for NAS – as a backup device. You can backup physical machines, Windows, Mac, Linux servers and also Vmware and Hyper-V hypervisors. Thats insane for that price. I hate Synolog to the core – but that 280USD price is unbeatable. You populate it with 2x4TB original Synology drivers /99USD/, which are the only not-overpriced ones, and you have much much better system than this UNAS2. I think that smallest Synology NAS /225+/ is the only one which still is relevant even with vendor HDD lock-in. Bigger units are no-go and there I see the space for Ugreen/UNAS/TrueNAS competition.

        For Both they should be able to use their existing Remote Access Network, Right?

      74. Thanks for your great reviews. I’m a newish Unifi user and am tempted by the 2 bay NAS. I have 2x 4TB HDDs I could use to storage my photos and mirror my 1TB OneDrive.
        Can I attach a 2TB SSD via USB-C and make it availe as another network share? Then I could use the fast and quiet SSD for most and the HDDs to archive stuff. Does seem possible and make sense?

      76. I really wish Ubiquiti would allow Docker and at least one m.2 for this device. However, I guess I can just install linux on a mini pc (to be a server) for Plex, immich, and other apps and then use this Ubiuiti NAS to hold all of the media for the mini pc?

        I really love Ubiquiti’s products but I may just pick up a Ugreen or similar for an all in one solution. Going to hold off on buying anything until I see reviews of the rest of Ubiquiti’s upcoming NAS lineup.

      115. The CPU sticking at a constant temperature is actually ideal.
        You want the silicon to be at a as consistent as possible temperature , my guess is that it’s a pretty minor heat and their intentionally not spin up the fan so that even when it’s idling, it is at that specific constant temperature that prevents any thermal expansion or contraction.
        You do not want your CPU to be significantly cooler when idling for endurance.
        Yes, lower temperatures are always better , but anything under 90° is absolutely fine nowadays.

        My situation: I take pictures of clients in a recurring fashion. I want them to login their account and they can see all the folders I’ve shared with them. These individual links are too primitive and having what should be sub-folders only be “Drives” would be way too unorganized.

      127. Im a current UNAS Pro owner. My unit is RAID 5 with a hot spare. Thanks for the timely opinions and update on the new features. The changes made so far are great for the average user, especially RAID 6 and an “easy” conversion from Raid 5. I hope it is indeed as simple as disabling the hot spare to make it happen w/out data loss. Also Im glad to hear Time Machine on private drives is supported and Admins can control all backup settings. All the other features you wish for, (to me at least), can wait and I won’t miss them. Thanks again for the followup!

      128. A lesson I learned a long time ago and very much applies to Ubiquity, assume the product is complete when you purchase it and won’t get updates. Does it have everything you need? I’ve learned that I can take quite a bit of time (years) for features to be added to UniFi products and even then they are still somewhat incomplete.
        They are clearly a company in a growth phase so I’d imagine lots of projects in the works but they really need to concentrate a bit more on the software experience.
        How does a NAS ship feature incomplete? There was no consumer rush on it. It’s a very odd product line at this point.

      133. I have SMB disabled along with shared links. This is a backup storage device to replace my DS418. However, I might go back to my DS418. The lack of NFS configration options is anoying. Subnet level access via NFS has been a thing since forever except when configured NFS on UNAS Pro. I should not have to enter every single individual IP address, and folder permissions, to the UNAS. Plus the fact that I am required to add a gateway and two DNS servers per network interface. Now, if DNS1 is my router, and my router goes down, what is the bonus of having a second DNS server in a NAS? Plus, what if I want to use 10Gbe as local link only and not route traffic? Why does a network mfg company require things that are not actually required? Filesystem snapshot recovery from the UI? Schedule snapshots, sure. Recovery snapshots. Nope.

      135. Raid 6 has slower write performance to Raid 5 due to calculating dual parity for the two disk redundancy.

        Raid 5 can survive only 1 disk failure but will rebuild array to fault tolerant with hot spare — The question then becomes how long to rebuild data from parity info. Obviously Raid 6 can survive 2 failures and still maintain data integrity- like all things it a compromise.

        Raid 10 gives best performance albeit at losing 50% of your aggregated disk capacity, but could in theory tolerate more than two drive failures. For example

        Best-case: 1 disk per mirror pair can fail — e.g., in an 8-drive RAID 10 (4 mirrored pairs), you could lose 4 disks if each failure is from a different pair.

        Key point: It’s not how many fail, but which ones.

      173. Excellent presentation. Thank you. I am trying to better understand the internal NAS snapshots. I reviewed your previous reviews and see where snapshots seem to exists. I use BTRFS snapshots with my Synology unit and they are basically instanteous and take up no “extra space” initially. I can bring up a file explorere of sorts on the Synology and easily drill down to directories on each set of snapshots looking for the file I want to restore. Do the UniFi NAS snap work like this as well? I really only use my current NAS units for SMB file storage and that storage is mainly file copies from other systems as backups. I need my NAS to have solid network performance and snapshots like I described. The UniFi unit is “fair” on the performance side with you showing roughly 375-475mb/sec read and writes – so it does about half with the 10GbE port can support. At $500, it would be a pretty good unit versus a Synology 1821+ (which needs 10GbE added) if it has good snapshots.
