There are several synonyms for the term fixed storage, including internal storage, non-removable storage, and embedded storage. Internal storage refers to the built-in storage space that is integrated into a device, such as a smartphone or computer. Non-removable storage refers to storage that cannot be removed from a device, such as a hard drive or solid-state drive.
