If you already have a capable NAS and you don't want another machine in the house to run as the brain of your audio system, running Roon Server on your NAS can be a great solution. If you have a large amount of content, a NAS can be a convenient and secure way to store it, especially if you have other personal media (photos, videos, backups). Another benefit is that NAS operating systems can provide RAID mirroring, which provides fault tolerance. However, remember that RAID mirroring is not an alternative to backup.

NAS devices are electrically and mechanically noisy, not optimized for high-performance audio, and not especially powerful (for their cost). With the arrival of large-capacity drives, most people no longer need a multi-disk NAS in the home because all their music can be stored on a single drive, and less expensive machines for running your audio system exist.

Roon Server runs on NAS devices using our official Docker image. To run Roon Server successfully, your NAS must meet the following hardware and software requirements:

• Processor: 64-bit x86_64 (amd64) CPU (Intel or AMD). ARM processors are not supported.

• RAM: 4 GB minimum.

• Storage: An SSD is strictly required for the Roon database. Your music files can remain on spinning disks.

• Software: The NAS must support Docker containers (e.g., Synology Container Manager, QNAP Container Station, ASUSTOR Portainer, TrueNAS SCALE Apps, Unraid Docker).

If you are buying or configuring a modern NAS specifically for Roon, we highly recommend choosing a model that includes dedicated M.2 NVMe SSD slots. This allows you to install a lightning-fast SSD for Roon's database without sacrificing any of your main hard drive bays.

An optimal modern NAS configuration looks like this:

• RAM: 8 GB or more. While our minimum requirement is 4 GB (which can generally handle libraries up to about 100,000 tracks), the actual requirement varies based on metadata complexity. Keep in mind that Roon is not the only software consuming memory on a NAS; the operating system and other apps/containers need RAM too. Therefore, 8 GB provides comfortable headroom.

• Database Storage: A 128GB or 256GB M.2 NVMe SSD installed in a dedicated slot for the Roon Server database and application files. Roon databases are relatively small, so you do not need massive capacity here—just speed.

• Backup: An external USB drive or a separate network location for automated backups of your Roon database and music library.

Why this works so well: Using a dedicated NVMe SSD provides the absolute best performance for Roon's database without using up a slower HDD. Upgrading the RAM ensures smooth, snappy operation when searching or browsing, especially as Roon evolves. The redundant HDDs give you massive, fault-tolerant storage for your music files, while a separate external backup strategy protects you from catastrophic hardware failure. Remember, RAID is fault tolerance, not a backup.

Roon stores its metadata and indexes in a custom database built for performance. This database is populated by Roon when it identifies your music files. It lives separately from your music files, and for performance reasons, it is highly recommended that the Roon database be on an SSD instead of a spinning disk. Your music files can be stored on spinning disks with no consequences to performance.

When running via Docker, you will map your NAS's local music folder directly into the Roon container (as /mnt/music:/music:ro)Using these local paths provides much better performance than scanning the NAS over the network via SMB.

Roon Server uses a lot more CPU than typical audio or media server software. While a slower CPU will usually handle basic playback just fine, you will quickly hit its limits if you use advanced features. The consequences of running on a weaker CPU potentially include:

• Stuttering or dropouts in audio playback.

• Slow response for searching.

• Slow loading of artist, album, composer, and work pages.

• Longer startup and connection times for remotes.

• Slower audio analysis for normalization and crossfading.

• Slower import of new music.

If you plan to use Roon's advanced features—such as DSP (Muse), heavy upsampling, EQ, or multi-room streaming to multiple zones simultaneously—we strongly advise choosing a more powerful CPU, such as an Intel Core i3, i5, or an AMD Ryzen equivalent.

Roon database performance is impacted most by the media the Roon database is run on. We don't run Roon databases on spinning disks, and neither should you. Will it work? Yes. Will you have the best Roon experience? No. Everything will be noticeably sluggish if you run it on a spinning disk.

Because Roon Server now runs inside our official Docker container, the core software environment is standardized across all platforms. You get the exact same Roon Server functionality as a standard Linux installation.

However, if you plan to connect a USB DAC directly to your NAS for audio playback, keep in mind that support for Native DSD output is still contingent on your NAS's host operating system having a kernel and ALSA drivers that support it. Additionally, you will need to configure your container to properly pass the USB device through from the host NAS to the Docker container.

Roon Labs provides an official Docker image for running Roon Server on NAS devices. This ensures you always have the most stable and up-to-date version of Roon Server.
