Portable Storage Device

Primary definition

Portable device that can be connected to an information system (IS), computer, or network to provide data storage. These devices interface with the IS through processing chips and may load driver software, presenting a greater security risk to the IS than non- device media, such as optical discs or flash memory cards. Note: Examples include, but are not limited to: USB flash drives, external hard drives, and external solid state disk (SSD) drives. Portable Storage Devices also include memory cards that have additional functions aside from standard data storage and encrypted data storage, such as built-in Wi-Fi connectivity and global positioning system (GPS) reception. See also removable media.
