The capability of a portable media device to store a large amount of data is best indicated by gigabytes. Gigabytes are a unit of digital information storage that represent approximately one billion bytes. This measure is commonly used to quantify the storage capacity of devices such as USB drives, external hard drives, and smartphones, providing a clear understanding of how much data can be stored.

Comparatively, bytes and megabits are smaller units of storage; bytes comprise eight bits, while megabits equal one million bits. While they can provide insight into storage, they do not typically convey the large storage capacities associated with modern devices. Kbps is a measure of data transfer speed rather than capacity, indicating how quickly data can be transmitted rather than how much data can be stored. Thus, gigabytes is the most suitable measure for understanding the storage capabilities of portable media devices.
