I wish for once they would really offer a unified storage-solution. But Yet it's all just a colelction of different storages with different interfaces, rules and so on. Google Drive has integrateion into all their services somehow, and Google Photos has some bad integration into Google Drive. But what about Google Books? Google Music? Google Mail? Youtube and all the other stuff they have? At best they have some import/export-functionalitity, not a real "One-for-all" type of filemanaging-solution. I haven't tested Google One yet, but it doesn;t seem to change anything there, just offering more space for them all.
