Several types of data storage exist in most computer systems. They vary in speed of access, cost per unit of data, and reliability.

* Cache: most costly and fastest form of storage. Usually very small, and managed by the operating system.
* Main Memory (MM): the storage area for data available to be operated on.
o General-purpose machine instructions operate on main memory.
o Contents of MM are usually lost in a power failure or ``crash''.
o Usually too small to store the entire database.
* Direct-access Storage (disk): primary medium for long-term storage.
o Typically the entire database is stored on disk.
o Data must be moved from disk to MM in order for the data to be operated on.
o After operations are performed, data must be copied back to disk if any changes were made.
o Disk storage is called direct access storage as it is possible to read data on the disk in any order (unlike sequential access).
o Disk storage usually survives power failures and system crashes.
* Tape Storage: used primarily for backup and archival data.
o Cheaper, but much slower access, since tape must be read sequentially from the beginning.
o Used as protection from disk failures!
