Terramaster F4-424 Pro 32GB Black
Score: 79/100Rankings
The ASUSTOR Flashstor FS6706T is a compact 6-bay all-SSD NAS delivering blazing 2.5 GbE performance and 4K transcoding. Its limitations include a modest 4 GB RAM base and the inability to use HDDs, which may restrict capacity flexibility. Best suited for content creators and small-to-medium businesses that prioritize speed over massive raw capacity.
The TerraMaster F4-424 Pro is a 4-bay NAS delivering desktop-grade performance with an Intel i3-N305 CPU, 32 GB DDR5 RAM and dual 2.5 GbE ports. Its lack of 10 GbE networking and limited M.2 bandwidth temper its appeal for high-throughput environments. Ideal for prosumer media enthusiasts and small businesses needing strong transcoding.

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.
Professional reviewers consider the F4-424 Pro the most powerful media-class 4-bay NAS on the market, lauding its desktop-grade i3-N305 CPU, 32 GB DDR5 memory, dual 2.5 GbE, HDMI 2.1 and NVMe caching. They commend its cooling redesign and tool-free bays, but criticize the immature TOS software, absence of 10 GbE/SFP+ and the limited PCIe Gen3 ×2 M.2 bandwidth.
Everyday users love the raw performance for 4K streaming, quiet operation, easy drive swaps and fast initial setup. Common frustrations revolve around the basic TOS app store, occasional firmware bugs, throttled M.2 speeds and the desire for easier RAM upgrades and a built-in battery backup.
