Performance Verdicts

Winner for LLM Inference

tie

Both have 0 GB memory, so bandwidth decides. Samsung SSD 9100 PRO 2TB PCIe 5.0 NVMe's 0 GB/s vs 0 GB/s translates directly to more tokens per second at equivalent model sizes.

Winner for Stable Diffusion / Image Generation

tie

Neither is optimised for image generation, but Samsung SSD 9100 PRO 2TB PCIe 5.0 NVMe's 0 GB/s bandwidth makes generation faster. Both run SDXL via Metal (macOS) or ROCm (Linux). Expect slower generation times than a discrete GPU.

Winner for Power Efficiency

tie

Both draw around 999W at peak load.

Overall Winner

5.0 NVMe wins

Samsung SSD 9100 PRO 2TB PCIe 5.0 NVMe edges ahead overall — better memory, bandwidth, and user ratings for local AI workloads. The gap is real but not always worth the price difference; assess based on your primary use case.

Frequently Asked Questions

Q1Which runs Ollama faster — Samsung 990 PRO Heatsink SSD 4TB NVMe M.2 or Samsung SSD 9100 PRO 2TB PCIe 5.0 NVMe?

Samsung 990 PRO Heatsink SSD 4TB NVMe M.2 runs Ollama faster. Its 0 GB/s memory bandwidth vs 0 GB/s means faster token generation — roughly — more tokens/second on the same model. On Llama 3.1 8B, expect around 0 tok/s vs 0 tok/s.

Q2Can either mini PC run Llama 3 70B?

Neither mini PC has enough memory for Llama 3 70B without heavy CPU offloading (39 GB required at Q4_K_M). You would need a Mac Mini M4 Pro with 64 GB unified memory or a discrete GPU with 24 GB VRAM paired with ample system RAM.

Q3Which is better value for local AI in 2026?

Samsung 990 PRO Heatsink SSD 4TB NVMe M.2 offers better performance-per-dollar for AI workloads due to its 0 GB/s bandwidth advantage. However, if price is the primary concern and 7B–13B inference is the goal, both get the job done — the gap matters more at higher workloads and model sizes.

Q4Which has better software support for local AI?

Both run Ollama well. AMD-based mini PCs offer ROCm acceleration on Linux; Intel-based ones are adding OpenVINO support. macOS Apple Silicon has the most polished Ollama experience.
