I tested two TerraMaster all-flash NAS products in the past — the F8 SSD Plus and F8 SSD — and both are my go-to recommendation if you need a storage system that can accommodate eight M.2 SSD drives. Just like the F8 SSD, the F4 SSD is powered by Intel's N95 platform, and it gets the same 8GB of RAM as standard.

I used four 2TB WD SN770 drives with the F4 SSD, and it held up just as well as the F8 SSD in my testing.
