In the future, for anyone with an internal SSD, partition the drive into 3 parts. Two small partitions that will hold an OS install each (maybe 60 gb ea) and the third partition will be for all documents.
One of the small partitions will be your boot drive that will hold your current OS. The 2nd small partition is for NEW OSes that you can install and try out "risk free". Doing it this way gives you an instant fallback plan if a new OS is crap. Or if you find the new OS is a keeper, it can become your new boot drive and the first partition will then be reserved for the NEXT new OS. No trauma. No big surprises. Easy Peasy.
In the past, before SSDs, partitioning a spinning hard drive meant that each subsequent partition would be slower than the previous one because it would reside closer to the inside of the spinning platter. But with SSDs it doesn't matter. All partitions are equally fast.
