Over time, OneDrive has improved, and its consumer version is now equal to both of its significant rivals. But OneDrive for Business, the commercial version, has struggled to keep pace for several fundamental reasons. The main reason is that it didn’t do an excellent job of syncing files and that it relied on aging SharePoint legacy infrastructure, which wasn’t designed for the cloud.
