And? You can buy a 2 terabytes HD for $50 or so(or less?). I suggest you do that if you want to store the blockchain, SD cards aren't reliable - HDs are cheaper and better. But guess what? Storage isn't the problem anyway.
The problem is that peers have to transmit and process the whole ledger.
And the answer "so called moore's law will magically solve everything" isn't too convincing.

I, the only one with a functional personal computer on my hallway (my own homebrew "Bellyache I", a comedic take on the famous "ILLIAC 4), my room became the "GBDSC", short for "Gigabyte Data Storage Center", a subsidiary of the organization "MOIA", short for "Ministry of Information Abuse", whose ominous motto was, "We've got a file on YOU!"
