Terramaster F4-425 review: an affordable 4-bay NAS for home backup and media

ZDNET tested the Terramaster F4-425, a 4-bay NAS that sells on Amazon for $379 (also listed at $399.99 at B&H). The unit supports up to 120TB of storage with drives you must buy separately and offers a compact, fast option for LAN-based file storage, backups and media serving. Setup is straightforward: insert drives, connect Ethernet, power up and use the Terramaster mobile app to discover the device and complete initial configuration.

A web-based UI provides file management and an app store for backups, snapshots, containers, photo management and sync tools. Performance impressed in ZDNET’s tests. Large multi-gigabyte video uploads completed quickly, and the device supports 4K transcoding and multimedia servers such as Plex, Emby and Jellyfin.

Key hardware specs include an Intel x86 quad-core CPU, 4GB RAM, a 2.5Gb Ethernet port, three M.2 SSD slots, multiple USB 3.2 Gen 2 ports, BTRFS/EXT4 file systems and claimed transfer speeds up to 1010 MB/s. The reviewer praised the sync feature but noted it requires some technical steps: installing the TNAS sync client on the NAS, adding the desktop client on each computer, and manually configuring IP, port, username and password.

Samba shares work for manual file access, but the reviewer suggested Terramaster ship the sync client by default and add auto-discovery to the desktop client to simplify setup for nontechnical users.
