I know that I have seen both of these addressed, but now can't find them. When I launched QU the first time, it asked me a question about rebuilding thumbs - was this all thumbs or just the raw thumbs? How much additional space will be needed? Secondly, where can I find a concise summary of what QU does with raw files that Studio does not do, and what this means in terms of time and storage space. Thanks much.
Q/Ultimate will rebuild all the thumbs because it has a higher quality thumb to offer. The thumbs that are not raw are built in a blink of they eye.
The thumbs for the raw files need extra time (one time only) to create and store a cached copy of the raw file.
The size of this cached copy is determined by the type of raw and the size / resolution of the raw file.
After the cached copies are created, the opening and closing, and adjusting, slide shows, full screen, image editor, comparator screen; all accesses of the raw image, are lightning fast.
There should be no space problem unless you keep 50,000 Raws on your hard drive, and Ultimate is going to cache them all.
Time to get more external space.

Hope some of this helps.
