Will intel's smart storage technology on my z270 board automatically transfer windows to an ssd if I add one to my build

Same as above

No, but it can automatically use it as a cache drive, if it is a proper sized SSD then cloning your HDD to your SSD would be better, assuming you are not building from scratch.

What does Intel Rapid Start technology do?
Simply put, Intel Rapid Start Technology uses a specially formatted and labeled disk partition (more on those details later) to write a copy of what's in RAM to an SSD at shutdown (or when going to sleep), and then reads that SSD information back into RAM as bootup gets underway.

That means no.

http://clonezilla.org/ can do that for you.

Many SSDs include cloning software. My Adata SSD did.
