1TB is not enough for render 15hour 4k video

Hi,

I would like to render a 15 hours video with 4k and 40bit rate.

However, the rendering of the video never ends completely, as the disk fills up during rendering and thus the entire rendering crashes.
During rendering, temporary files (tmp) are created on the disk, which are combined into one mp4 file at the end. But the disk is not enough for this render. How to solve this situation?
The disk has 940 GB free.
