@Omanimous Without knowing the exact details. A 128GB disk (ssd or hdd) from two different manufacturers are usually different sized down to the byte level. So in theory if your source disk is one byte larger than your destination disk a non-resize FOG image will fail.

I can say for my reference image (which I deploy to all hosts), I create on a VM with a 40GB hard drive. That way I’m assured it will deploy to all hardware on my campus. For win10 I use a 60GB reference image.

With FOG 1.2.0 I used non-resizable and then let windows expand the disk. With the 1.2.0 trunk build FOG expands the disk now. I still use a 40GB reference image for Win7. So I always go smaller to larger when the image is deployed.
