Stating the problem We need a type of new mass storage that can break both barriers of Access times Minimum entry cost New mass storage should also be significantly New mass storage should also be significantly cheaper than non-volatile RAM cheaper than non-volatile RAM $100 now buys 1 GB of flash memory $100 now buys 1 GB of flash memory
