- Secondary storage refers to storage devices and their media that are not directly accessible by the CPU12. Data needs to be transferred to primary storage to be available1. Secondary storage includes hard drives and non-volatile random-access memory1. These devices are slower than RAM but non-volatile, meaning they retain their contents when powered down2.Learn more:✕This summary was generated using AI based on multiple online sources.
