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 TS-873A-8G is an 8-bay NAS with an AMD Ryzen quad-core processor, expandable up to 64 GB RAM and dual 2.5 GbE ports, delivering strong performance for demanding workloads. It lacks built-in 10 GbE and has a relatively high active power draw. Suited for small-business labs and media servers requiring large capacity and virtualization.

Professional reviewers consider the TS-873A a solid high-performance NAS that delivers high compute performance for virtualization and media transcoding; eight hot-swappable bays provide up to 64 TB of raw storage; dual 2.5 GbE ports enable faster network transfers; expandable DDR4 memory up to 64 GB with ECC support ensures data integrity; multiple USB 3.2 ports for high-speed peripheral connectivity; optional PCIe slots allow adding 5 GbE/10 GbE adapters for future network upgrades.
Direct consumer reviews are scarce, but the specifications suggest users would likely appreciate the high-speed connectivity, transcoding performance and flexibility for multiple workloads. Potential concerns that surface in discussions revolve around the limited two-bay design and the non-expandable 8 GB RAM, which may restrict future growth.


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.
