UniFi UNAS Pro – SIX MONTHS LATER

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!
