With sd cards and flash memory getting larger and more affordable there is no need for anything else. It is also one of the fastest possible types of memory if implemented in the right way. Why waste space for a HDD or drive if the same amout of memory fits into a SD or micro SD card, in the future even for a lower price.
Cardridges are the fastest possible storage, faster than any HDD or optical media could ever be. And production costs will soon be lower too.
