Google Drive is described as the ultimate cloud storage service that is integrated with Google's other apps like Gmail, Calendar, and YouTube. It provides 15GB of free storage that can be accessed from Android devices, Chromebooks, and online. While storage is shared across Google services, Google Music does not count against the storage limit. Google Drive allows users to store any type of file, share files how they want, and offers a powerful search function along with integration with Google Photos, Docs, Sheets, Slides, and Forms.
