Professional reviewers commend the FS6706T for its blistering all-flash performance that pushes the limits of 2.5 GbE, its silent operation, and robust 4K transcoding for Plex streaming, while noting the base 4 GB RAM and lack of HDD support as trade-offs.
Home users and small-business owners praise the fast SSD speeds, quiet operation and low energy use, but note occasional concerns about limited memory and the inability to add traditional hard drives.

“TerraMaster's Best NAS Yet”
Professional reviewers consider the F4-425 Plus a well-rounded, mid-range NAS that delivers a notable performance uplift thanks to its Intel N150 processor, 16 GB DDR5 memory, and dual 5 GbE ports. The hybrid storage architecture and three M.2 slots are highlighted as differentiators, while the non-ECC memory and limited M.2 bandwidth are cited as the main compromises.
Everyday users generally praise the device for its massive capacity, fast NVMe caching, and future-proof 5 GbE networking, especially for home media and small-office workflows. Recurring complaints focus on the limited SSD lane bandwidth, underused HDMI port, and the bulk of the external power brick.
