The F4-425 Pro combines an Intel N305 8-core processor, dual 5GbE and three M.2 NVMe slots in a 4-bay NAS. TOS 7 adds the OpenClaw AI agent, online office editing and fast global search.
What the F4-425 Pro does for your data
The Intel N305 8-core processor and 8 GB of memory run several demanding tasks at once.
Two 5GbE ports reach up to 1020 MB/s with link aggregation, and three M.2 NVMe slots with Hyper Cache speed up the disk array.
TOS 7 integrates the OpenClaw AI agent: natural-language commands, AI tasks processed locally by default and more than 500 APIs for custom workflows.
Edit Word, Excel and PowerPoint files online and find any file across all volumes with the new global search.
TRAID supports mixed-capacity drives and online array expansion, alongside RAID 0, 1, 5, 6 and 10.
The Business Backup Suite, TFSS snapshots and HyperLock-WORM support a 3-2-1 backup strategy and help defend against ransomware.
