Ubiquiti Launches UniFi UNAS Dual and Quad Bay Desktop NAS Series

Ubiquiti has unveiled its UniFi UNAS desktop NAS series that includes the UNAS 2 (two-bay) and UNAS 4 (four-bay) models each targeting different storage and performance needs. The UNAS 4 with its four bays, stands as the top model in the series featuring a quad-core Arm Cortex-A55 processor operating at 1.7 GHz paired with 4 GB of system memory. It can hold both 2.5-inch and 3.5-inch drives, and has room for two M.2 NVMe SSDs. This device is 246 x 129 x 224.5 mm in size and weighs 2.6 kg. Users can swap drives while the system is running, set up RAID, and use hot-spare features. The drives can use up to 80 W of power, while the whole system tops out at 90 W through PoE+++ power delivery.

The smaller UNAS 2 is made for less demanding setups offering two 3.5-inch drive bays in a 135 x 129 x 223.7 mm case. While lacking hot-swap functionality and NVMe support, it retains the same processor, memory configuration, and networking options as its larger sibling. Power consumption drops to 60 W via PoE++ delivery.
Both models feature 1.47-inch color displays, Bluetooth 4.1 connectivity, and polycarbonate construction. Management occurs through Ethernet interfaces integrated into Ubiquiti's UniFi ecosystem. According to IT Home, pricing starts at $199 for the UNAS 2 and $379 for the UNAS 4, with availability scheduled for Q4 2025.

This is awesome, maybe it will light a fire under synology's ass to stop their recent bullshit.

Ubiquiti is not perfect, but this price point and the features they bring look very enticing

The past few releases of their most important software (OS and Network) were disastrous. They launched 3 consecutive updates that they needed to pull immediately when the forums filled with complaints of things totally breaking, and they released fixed updates days later. Then they released a big update that was the worst in years but they didn't pull it, they let users complain for a month with network devices that wouldn't start or work properly anymore. Then a month later they pushed an RC version to fix these issues which, you guessed it, had entirely new things that were breaking. And another month+ long ongoing wait, maybe this time for real they fix the issues.

I'm still on an ok version on my network built on high end Ubiquiti gear (gateways, switches, APs), so just watching and waiting but would hate to be in such a situation with garbage software affecting my data. That's an order of magnitude higher impact than "just" network issues.

Synology also killed HEVC transcoding!!


Among other things like requiring their own branded drives which are just firmware flashed toshibas.

And the whole debacle with the wd red drives..

NASty behavior from synology

Same here. Have had unifi aps for 12 years and just recently ditched my meraki router and switch for unifi cloud gateway ultra and unifi switch ultra 60w!!

This may be a stupid question, but how much of an impact does it make on your electrical bill?

I save more! Merakis used a lot more. UPS runtimes during the last 2 huge outages: 6 hours for ubiquiti runtime off an apc backups 1080ns vs 4.5hrs for meraki runtime

How much more? Can you give a rough estimate?

Well it's harder to determine the actual dent in my electric bill cuz they are jacking it up cuz electric companies because of ai data centers are jacking up everyone's rates...plus been using the AC more than normal

I don't have precise numbers but the power supplies on the merakis are beefier and more watts then the ubiquitis. By far. I can power the ubiquiti w usbc and a battery pack if I needed to, but couldn't on the merakis
