TerraMaster F4-425 Plus (4-bay) and F2-425 Plus (2-bay) hybrid AI NAS systems are upgrades to the earlier Intel N95-based F4-424 and F2-424 NAS systems with an Intel N150 processor, dual 5GbE ports (up from 2.5GbE), and up to three M.2 SSD slots for up to 144TB of hybrid storage.
Both models feature DDR5 memory (up to 16GB), 4K/8K video transcoding, and support TerraMaster’s TRAID technology for improved performance and data redundancy. They also offer USB expansion options and quiet cooling, making them NAS solutions suitable for home and business use.

The devices run TerraMaster’s TOS 6 operating system, offering a user-friendly interface for application management, data backup, and system configuration. It supports Docker and VirtualBox virtualization, RAID management through TRAID, and backup synchronization with Google Drive, OneDrive, and Amazon S3. The system also includes AES-NI hardware encryption, HyperLock-WORM protection, AI-powered photo recognition, and built-in support for Plex, Jellyfin, and Emby servers for secure and efficient data, media, and application management.
The main benefits of the Terramaster NAS systems compared to other Intel N150-based solutions are the availability of 5GbE networking and SATA bays, features that are missing on products like the Beelink ME Mini and CWWK X86 -P6 with 2.5GbE networking and M.2 slots only.
In our previous post (linked above), we mentioned that the older F2-424 2-bay NAS and F4-424 4-bay NAS were not powerful enough, and how the F4-424 Pro with the Core i3-N305 was priced way too high at around $700. It looks like the company has addressed those issues and found a middle-ground solution, as the new 4-bay F4-425 Plus goes for $569.99, while the 2-bay F2-425 Plus sells for $399 on Amazon, and that’s before clicking on the $85 or $60 coupon currently available on Amazon. More information is available on TerraMaster’s website and the press release.
