Asustor Flashstor 6 FS6706T
Score: 83/100Rankings
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 QNAP TR-004U is a 1U rack-mountable 4-bay expansion enclosure that offers flexible RAID options and hot-swappable trays. Its reliance on USB 3.2 Gen 1 and lack of built-in networking can limit throughput. Ideal for data-center environments needing compact local storage expansion.

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.
