; [[Random access]]: Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage. Most [[semiconductor memories]], [[Flash_memory|flash memories]] and [[hard disk drive]]s provide random access, though both semiconductor and flash memories have minimal [[latency_(engineering)|latency]] when compared to hard disk drives, as no mechanical parts need to be moved.
; [[Sequential access]]: The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.
