ASUSTOR Flashstor 12 Pro Gen2 (FS6812X) vs TerraMaster F8 SSD Plus
Updated
Which should you buy?
The Flashstor 12 Pro Gen2 is the stronger all-flash NAS: twelve M.2 slots, ECC memory up to 64GB, two 10GbE ports and two USB4 ports. The F8 SSD Plus is smaller and cheaper with eight slots, one 10GbE port and a 32GB memory ceiling. Neither has a GPU path, so both suit RAG storage more than running models.
What is the difference between the Flashstor 12 Pro Gen2 (FS6812X) and the F8 SSD Plus?
Both are compact all-flash NAS systems with no hard drive bays, and both are AI Capable rather than AI Ready: neither has an NPU, a capable integrated GPU or a slot for a graphics card. Their role in a local AI setup is fast, private storage for documents, photos and model files.
The Flashstor 12 Pro Gen2 has twelve M.2 slots on mixed PCIe lanes, a quad-core Ryzen Embedded V3C14, 16GB of ECC DDR5 expandable to 64GB, two 10GbE ports and two USB4 ports. ASUSTOR officially lists Ollama with Open WebUI in App Central for it.
The F8 SSD Plus has eight M.2 slots, each PCIe 3.0 x1, an eight-core Core i3-N305 with UHD graphics, 16GB of DDR5 in a single slot with 32GB as the ceiling, and one 10GbE port. TerraMaster documents Ollama in Docker for its x86 systems.
The ASUSTOR holds more drives, more memory with ECC and doubles the network bandwidth. The TerraMaster is smaller and lighter on power. Neither will run large models quickly.
A good pattern for either is to pair it with a separate GPU machine: the NAS holds the document library and runs the embedding model, and the GPU box answers the questions over the network. With two 10GbE ports the ASUSTOR handles that traffic more comfortably.
Choose the ASUSTOR Flashstor 12 Pro Gen2 (FS6812X) if
You want the most flash capacity and network bandwidth in a small box, ECC memory for an always-on server, and room for an embedding model and a small assistant alongside a large RAG library. Two USB4 ports and official Ollama support in App Central are a bonus.
Choose the TerraMaster F8 SSD Plus if
You want quiet, low-power flash storage for a desk or studio at a lower price, eight slots are enough, and one 10GbE port covers your editing or document library. You accept a 32GB memory ceiling because the NAS will mostly store files rather than run models.

Which can run bigger local models?
The ASUSTOR Flashstor 12 Pro Gen2 (FS6812X) reaches 64GB of memory against 32GB on the TerraMaster F8 SSD Plus. That is the difference between 32B class models comfortably, and 70B class models at 4-bit with little headroom and models up to the 14B class, with 32B class models a tight fit (Estimated). The largest 4-bit model each can hold is roughly 93B and 40B parameters, after leaving 8GB for the operating system.
For GPU acceleration, the ASUSTOR Flashstor 12 Pro Gen2 (FS6812X) has no way to add a graphics card, while the TerraMaster F8 SSD Plus has no way to add a graphics card. A discrete card with its own memory is the biggest single speed upgrade for local models, so this matters more than CPU cores for anyone planning to run 14B models or larger.
