Synology DS925+ vs UGREEN iDX6011
Updated
Which should you buy?
For local AI the UGREEN iDX6011 is in a different class: a Core Ultra processor with an NPU, 32GB or 64GB of memory and UGREEN's own assistant, against the DS925+'s four-core Ryzen with no graphics. Choose the Synology for its backup and sharing software and lower price, not for running models.
What is the difference between the DS925+ and the iDX6011?
Many people searching for an AI NAS are weighing a Synology they trust against a newer AI-first brand, and this pairing shows the trade-off clearly.
The DS925+ is a four-bay Synology running DSM, with a quad-core Ryzen V1500B, 4GB of ECC memory expandable to 32GB, two M.2 slots and two 2.5GbE ports. It has no integrated graphics, no NPU, no PCIe slot and no 10GbE upgrade path. Community guides show Ollama in Container Manager running small models on the CPU, and Synology AI Console can connect DSM to a model running elsewhere.
The iDX6011 is a six-bay UGREEN with a Core Ultra 5 125H, Arc graphics and an 11 TOPS NPU, 32GB or 64GB of soldered memory, two 10GbE ports and an internal PCIe Gen4 x8 slot. UGREEN's Uliya assistant runs on it locally.
In practice the Synology suits 1B to 3B models slowly, while the iDX6011 runs 14B to 32B class models depending on memory (Estimated). The DS925+ costs much less and DSM's backup tools remain the benchmark.
There is a middle path worth knowing about: keep a Synology for storage and point AI Console or Open WebUI at a model server on another machine. That gives you DSM's reliability and real model speed, at the cost of running two boxes.
Choose the Synology DS925+ if
You want dependable storage, Hyper Backup, Synology Photos and Drive, and AI is something you will run on a separate machine through AI Console. Four bays and 2.5GbE are enough for your household, and you value the DSM ecosystem and its long update record over raw compute.
Choose the UGREEN iDX6011 if
You want the NAS itself to run your private assistant and search your files, with two 10GbE ports, six bays and a GPU slot for later. UGOS Pro is acceptable to you in exchange for real local AI hardware.

Which can run bigger local models?
The UGREEN iDX6011 reaches 64GB of memory against 32GB on the Synology DS925+. 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 Synology DS925+ has no way to add a graphics card, while the UGREEN iDX6011 offers pcie x8 slot. 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.
The UGREEN iDX6011 has a 11 TOPS NPU. NAS NPUs help vendor features such as photo recognition and search, but most open-source LLM runtimes do not use them yet.
