Mmm, that's odd since I thought cloning was a sector by sector copy. What did you use for cloning? Some software uses an Intelligent Copy such as Macrium Reflect but I didn't know this was the default. Plus I would have thought the ssd would have been a lot smaller if it had done this. But I don't know much about what it does actually copy. FWIW: From Macium Blog - Intelligent sector copy - Copy only file system sectors/clusters that are in use. This reduces the time to create the clone as unused file system clusters are not copied.
I did the first clone yesterday evening and did not compare the 2 disk properties until this morning ... after I had briefly used the computer AFTER the cloning. So OF COURSE the 2 disk properties would not match.
So I just finished re-cloning the C: drive -- immediately after checking the C: properties -- and now you can see how close the numbers are, only a 7 file difference:
