I use Google Workspaces at work, and I have configured my notebook more like a netbook. Every possible file and folder gets stashed in Drive, and the agent runs to integrate with the Windows filesystem. This is especially important for Company Data and Confidential Materials.

I have modest storage needs in my role, but imagine a developer, Big Data user, or video editor used it. As long as they could tolerate the latencies, they might stash quite a bit in there.
