In an information system, mass storage is that type of memory, also called secondary memory in contrast to the main memory, able to collect large amounts of data in a non-volatile mode. Therefore, the memory device used at this scope must be able to mantain the availability of the data stored, even after its disconnection from the main system or after switching off/restarting the system itself.
Such computer devices are hard disks, optical/removable media such as CDs, DVDs and BlueRays, drives using magnetic media, USB drives and Flash/Nand memory cards, and network storage units, from cheap NAS to the much more expensive SAN/DAS.
