yes

will its size decrease or it expand on its own?

it will stay the same.  other drives are 72gb so only 72gb of this 300gb will be used
all drives in a raid array have to be the same size.  the physical disk can be larger though the difference will be unused
they don't make 72gb drives anymore

after doing hot replacement do I have to do anything from Array Configuration?

should rebuild automatically
