Updating my previous post due to new information. From QNAP…
2026/02/13
[New Features]
- Added support for NVIDIA RTX 50 series and Blackwell architecture GPU cards.
[Important Note]
- NVIDIA GPU Driver 6.2.2 will install NVIDIA GPU driver version 575.64.05 and then select the kernel driver type (open-source or proprietary) depending on what NVIDIA GPU cards are installed on your NAS device.
[Compatibility]
- QTS/QuTS hero firmware versions 5.2.9 and later are only compatible with certain versions of NVIDIA GPU Driver 6.2.2 and later. When updating QTS/QuTS hero firmware, it is recommended to update NVIDIA GPU Driver first to avoid the system automatically disabling NVIDIA GPU Driver due to compatibility issues.
So it seems they have added support for Blackwell, you’ll just need to make sure the 4000 pro physically fits inside the case.
Let me know how it goes!
