I want to know why Cisco has added the storage option in C9000(c9200,c9300,c9400,c9500,c9600) series switches?
And what are the applications in c9000 switches those need the storage?

You will get more details.
Cat9k supports Docker powered container architect, that allows you run different container based applications, some of them need more storage than the basic capacity of a default config
