F4-425 vs Plus vs Pro vs D8 Hybrid 2 Which TerraMaster Fits You?
Three four-bay NAS boxes and one eight-bay DAS enclosure. The differences come down to networking, NVMe slots, CPU and whether you need a network at all.
So which TerraMaster should you actually buy?
For most people, the F4-425 Plus. It has the best review record of the group (18 reviews, 4.7 average), dual 5GbE and three NVMe slots, and it starts at $509.99. Choose the plain F4-425 at $364.99 if you just need simple storage and streaming, and the Pro if you want an N350 with 16GB for Docker or heavy transcoding. The D8 Hybrid 2 is a different product entirely: a USB DAS for one computer, not a NAS.
Three NAS tiers and one DAS
The F4-425, Plus and Pro share the same four-bay concept with different CPUs, RAM, networking and M.2 support. The D8 Hybrid 2 breaks from the pattern and connects directly to a computer over USB-C. All four list a 2-year warranty.
