Hard disk drives (HDD), RAM, SSDs, and cache memory are all examples of digital memory. Is it beneficial to have many memory standards or would it be better for consumers if there was just one, similar to SSD sizes? Is a unified standard less expensive and more convenient for consumers? There are two types of memory access: sequential and direct. Why are essential devices increasingly using direct access? How can we move data from one device that only enables sequential access to another that only supports direct access?
