Digital memory includes hard disc drives (HDD), RAM, SSDs, and cache memory. Is it better to have many memory standards or would it be better for customers if there was just one, like SSD sizes? Is a single standard cheaper and more convenient for consumers? Sequential and direct memory access are two ways. Why do key gadgets increasingly utilise direct access? How can we transfer data from a device that only allows sequential access to one that only supports direct access?
