What term refers to storage devices that can be moved from computer to computer without opening the case?

Removable storage refers to storage devices designed for portability, allowing users to easily transfer data between different computers without the need to physically open a computer case. Common examples of removable storage include USB flash drives, external hard drives, and CDs/DVDs. These devices provide convenience and flexibility, making it simple to back up data or access files on multiple systems.

Hot-swappable devices, while they can be installed or removed while the computer is running, are typically internal components, like certain types of hard drives, that require specific hardware support and are usually not designed for moving between different computers easily. M.2 SSD is a specific type of internal storage that often requires installation onto the motherboard and is usually not portable in the same manner as removable storage. Hybrid drives, which combine HDDs and SSDs, are also typically internal components and do not fit the definition of a device that can be easily moved from one computer to another without accessing the case.

Thus, removable storage is distinctly characterized by its ease of transport and the ability to be used across multiple systems without the need for hardware intervention.
