Concept explainers

Parallel and Distributed Storage
A parallel storage file system is a sort of clustered file system. A clustered file system is a storage system shared by multiple devices simultaneously.
Question

Digital memory includes HDDs, RAM, SSDs, and cache memory. Should consumers have many memory standards, like SSD sizes, or just one? Can customers save money with a single standard? Direct memory access may replace sequential access. Why are critical devices embracing direct access? Can data be transferred from direct-access to sequential-access devices?
