Google Drive for desktop or local disk?

Hi.

My students want to be able to work from a computer at home as well as on the computer at school. Does working against Google Drive desktop work well or is it always better to work against a local hard drive? Is there a risk that editing will be slow when you have to constantly sync against a cloud? From what I understand, it's always best to store the files locally on the computer. So we've never tried anything else. We don't have the option to use Lucidlink, for example. Grateful for your advice!
