Score: 82/100
Terramaster F4-425 Plus 16GB
Score: 84/100Rankings

The TerraMaster F4-425 Plus is a 4-bay hybrid NAS delivering dual 5 GbE connectivity, 16 GB DDR5 memory, and 8K transcoding capabilities. Limitations include PCIe x1 M.2 bandwidth and non-ECC RAM, which may affect high-end workloads. Designed for media-rich home or small-office environments seeking high capacity and fast cache.

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.

“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.
