AI NAS Deals – Prime Big Deal Days 2026
An AI NAS runs local language models on the NAS itself, and the deciding number is memory. The iDX6011 Pro has 64GB fixed, the DXP4800 Pro and Minisforum N5 Pro take SO-DIMM upgrades, and NVMe drives hold the models. This page prices each combination today and states which of a 7B, 14B or 32B model fits in memory.

Verdicts: Our tracked low is at or below the lowest price we recorded before today; within 3% is close to it; cut vs list only is below Amazon's reference price but above our low; no history yet means we make no claim. The 90-day line shades the event days. Was prices are Amazon's reference prices.
The Biwin NV7400 4TB at $415.99 is our tracked low: the lowest we recorded was $489.99 on Sep 29. Of 16 rows, 4 are at or near our low, 0 are cut only against Amazon's list price, 0 cost more than usual, and 12 have no history yet. The AI NAS units are newly tracked; the NVMe drives that go in them carry real verdicts from their own price history. Hard drive prices have risen through 2026 on AI datacenter demand (why hard drives cost more in 2026), so a price that only matches our low is a better outcome than in an ordinary year.
Which local LLM fits, at today's prices
Memory needed at 4-bit quantization (Q4_K_M weights plus about 2GB of context), with 6GB held back for the NAS itself. This says whether a model fits in memory, not how fast it runs. Totals add a AData Legend 710 PCIe Gen3 x4 2TB for model storage.
| Combination | Memory | 7B (needs 12.7GB) | 14B (needs 17GB) | 32B (needs 27.9GB) | Total today |

Frequently asked questions
How much RAM does a local LLM need on a NAS?
At 4-bit quantization, roughly 5GB for a 7B model, 9GB for 14B and 20GB for 32B, plus about 2GB of context. We also hold back 6GB for the NAS itself, which is why 32GB is the practical floor for 32B.
Does the fit table say how fast a model runs?
No. It only says whether the model fits in memory. Speed depends on the CPU, integrated GPU or NPU and the runtime you use.
Can I upgrade an AI NAS later?
The iDX6011 Pro's memory is soldered. The DXP4800 Pro and Minisforum N5 Pro take SO-DIMMs, so buying a smaller kit now and upgrading later is possible.
Where should the models be stored?
On NVMe, not hard drives: loading a 20GB model from a hard drive takes minutes. A 2TB NVMe holds dozens of quantized models.
