The TerraMaster F4-425 Pro is a diskless 4-bay desktop NAS with an Intel N350 8-core processor, 16GB DDR5, dual 5GbE ports, and three M.2 slots, suited to creators and small teams handling shared files, video workflows, and virtualization.
Recommended For
- Home-media collectors who want a four-drive library for streaming movies and music, with room to add SSD storage for apps or frequently used files.
- Creators and small teams who keep large working files on a shared NAS and have compatible 5GbE networking for faster transfers; reviewers measured performance close to the 5GbE link’s practical ceiling.
- Home-lab users who want one desktop system for storage plus Docker containers, development services, or lighter virtualization workloads.
- Households or small offices consolidating backups, media, and surveillance footage on a shared four-bay system, especially when flexible drive arrangements and multiple network connections are useful.
Real-World Use Scenarios
- Back up and sync files from several home or work computers to one shared location; TOS 7’s centralized backup can create jobs from network shares without installing backup software on every computer.
- Run a home Plex or Jellyfin library for movies and shows; testing found the F4-425 Pro handled 4K playback through Jellyfin, while reviewers also identify media streaming as a practical use for this NAS.
- Keep family photos backed up in a private library and browse them with an app such as Immich; Notebookcheck tested Immich on the F4-425 Pro, including photo processing after uploads.
- Host several self-managed services—such as Jellyfin, Immich, or a personal cloud—in Docker; testing showed the NAS running multiple Docker apps together, making it suitable for a home-lab setup as well as file storage.
- Share large project files across a wired multi-gigabit home or studio network; benchmark testing reached roughly 530–584 MB/s over a 5GbE connection, so actual transfer speeds depend on the client, network, and installed drives.
- Store and review recordings from compatible home IP cameras using the NAS’s surveillance software; this can centralize footage, though remote viewing requires network configuration.
