UGREEN iDX6011 Pro vs Zettlab D8 Ultra
Updated
Which should you buy?
The Zettlab D8 Ultra offers more on paper: eight bays and memory upgradeable to 96GB. The UGREEN iDX6011 Pro has the faster Core Ultra 7 255H, an internal PCIe slot plus OCuLink and a three-year warranty, and you can buy it in the UK today, which the D8 Ultra could not be in October 2026.
What is the difference between the iDX6011 Pro and the D8 Ultra?
These are the top models from two brands building AI-first NAS systems. The D8 Ultra is the eight-bay sibling of Zettlab's D6 Ultra: a Core Ultra 5 125H with Arc graphics, 32GB of DDR5 expandable to 96GB, two M.2 slots, two 10GbE ports, two USB4 ports and an external PCIe 4.0 x8 connector. Raw capacity reaches around 200TB.
The iDX6011 Pro has six bays but a faster processor, the Core Ultra 7 255H with 16 cores, Arc 140T graphics and a 13 TOPS NPU. Its 64GB of LPDDR5X is soldered. GPU options are stronger: an internal PCIe Gen4 x8 slot that UGREEN documents for NVIDIA cards, plus OCuLink.
For model size the Zettlab wins once upgraded, with 70B class models at 4-bit in reach at 96GB (Estimated). For speed on models that fit in 64GB, the UGREEN's faster CPU and graphics give it the edge.
We have not found a hands-on review of the D8 Ultra itself; its AI features follow the D6 Ultra reviews of the same platform. The UGREEN is in UK stock with a three-year warranty.

That is the difference between 70B class models at 4-bit with room left for longer context and 32B class models comfortably, and 70B class models at 4-bit with little headroom (Estimated). The largest 4-bit model each can hold is roughly 146B and 93B parameters, after leaving 8GB for the operating system.
For GPU acceleration, the UGREEN iDX6011 Pro offers pcie x8 slot, while the Zettlab D8 Ultra 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 Pro has a 13 TOPS NPU; The Zettlab D8 Ultra 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.
