TerraMaster rolls out the F4‑425 Pro, a modest lift over the 2025 F4‑425 Plus. The unit ships with an Intel Core 3 N350 8‑core CPU and 16 GB DDR5 RAM, a jump that adds a steep price tag but keeps the chassis identical. Buyers still enjoy the familiar, fan‑powered design and its quiet operation makes it suitable for home offices.

Software arrives with TOS 7.0.0616, built on Linux kernel 6.12. TerraMaster claims native AI support, driven by OpenClaw, though the feature set feels nascent. Engineers reportedly refined over 1,000 functions and added 50 new ones in the past year, aiming to smooth file‑system handling and expand RAID options for users and administrators across regions globally today and tomorrow.

The Pro supports up to 144 TB of raw storage—four 30 TB HDDs—plus 24 TB of NVMe caching across three 2280 slots. Dual 5 GbE ports and multiple USB 3.2 Gen 2 connections keep it competitive, while an HDMI 2.1 output opens media playback options. Power consumption data remain undisclosed, a common omission in NAS specs for ease of understanding in the.

Priced at $800 before VAT, the F4‑425 Pro sits roughly $100 above the cheaper Core i3‑N305 variant. For enthusiasts seeking higher core counts, the upgrade costs justify the performance gains. TerraMaster’s consistent hardware design and updated OS suggest a focus on reliability, positioning the Pro as a solid choice for small‑business NAS deployments in today's market environment.
