OneDrive is not only a place where you can store your files. So, if we have to explain it generally, “What is OneDrive?” The most common answer you would hear is something on the lines of “it is a place where we can store text, music, video and other files and access it anytime anywhere.” Although that is indeed the case, there is a lot more about OneDrive than a simple file storage system on the cloud. In Plan 2, you get unlimited storage at $10 per month, which can be a complete substitute for physical SAN storage devices. While it is available to all users for free, OneDrive for Business allows users to store up to 1 TB of data for Plan 1. OneDrive also has two standalone plans: Plan 1 (1 TB storage) & Plan 2 (unlimited storage).

OneDrive for Business is available with all Office 365 Business plans: Business, Business Premium, ProPlus and Enterprise plans: E1, E3, E5. OneDrive is a cloud storage service by Microsoft that allows users to store files on its remote servers. What is OneDrive for Business and How to Get It?
