TerraMaster has launched the F4-425 Pro, a new AI-powered NAS aimed squarely at creative teams, photographers, videographers and small businesses that need fast, centralised storage without the usual NAS setup headaches. The new four-bay model arrives alongside TerraMaster’s TOS 7 operating system, which the company is positioning as an AI-native NAS platform built around natural language control, local AI processing and automation.

The headline here is the combination of performance and workflow automation. The TerraMaster F4-425 Pro is built around an Intel N350 8-core processor, 16GB of DDR5 memory and dual 5GbE networking, with TerraMaster claiming combined throughput of up to 1010MB/s when the network ports are bonded. That puts it into interesting territory for small studios working with large stills libraries, multi-camera video projects and shared editing environments.

For photographers, the most appealing part may be the hybrid 4+3 storage design. There are four 3.5/2.5-inch SATA drive bays and three M.2 2280 NVMe slots, so you can use high-capacity hard drives for the main archive and SSDs for faster pools or caching. TerraMaster’s specification page lists 120TB of internal raw HDD capacity from four 30TB drives, while the launch information points to a higher total when the M.2 SSD capacity is included.

I’m particularly interested in how TOS 7 will handle real-world photo organisation. TerraMaster says the system can use on-device AI for facial recognition, automated file sorting and semantic analysis, with data processed locally rather than sent to the cloud. That could be very useful for anyone managing years of RAW files, client galleries, behind-the-scenes video and delivery folders.

This sits neatly alongside the sort of storage workflows we’ve already been exploring on Camera Jabber. Anyone comparing studio NAS options should also read our UGREEN DXP4800 Plus review, which looks at another four-bay NAS designed for photographers and videographers. For those building a wider backup system, our guide to the best portable SSDs for photographers is useful for field backups before files are moved onto a central archive, while our tutorial on how to back up your digital photographs safely is still a good starting point for thinking about redundancy.

The AI assistant element is also worth watching. TerraMaster says OpenClaw can interpret requests such as creating shared folders, setting snapshots and automating tasks, while the wider TOS 7 system includes more than 500 RESTful API endpoints for custom workflows. For a busy studio, that could mean less time spent configuring permissions, backups and storage tasks manually, and more time actually working on images and video.

Security is another major part of the launch. TerraMaster is promoting BBS Proactive Defense, HyperLock WORM protection and automated 3-2-1-0 backup as part of the F4-425 Pro’s data-protection story. As ever, we’ll want to see how this performs in practice, but the direction makes sense: a modern NAS for creators cannot just be a big box of drives; it has to help protect the work sitting on them.
