Sony would like you to know that its latest lineup of 16 gigabyte "Pocketbit" USB sticks will work just fine with Dragon Quest X.
Sony knows they work because they conducted internal tests to make sure. At least that's what the Pocketbit lineup page says:
If decide to power your Dragon Quest X experience through Sony hardware (partially), make sure you pick up a 16 gigabyte stick, as that's the minimum requirement.
