Google Drive does appear to have performance issues with big data sets. I too have a lot of data (20GB +) in the service and whenever I restart my machine, it does churn the CPU "scanning the web" for changes. Memory usage is also rather high at 600MB. I have never really used dropbox so I don't know if that is really any better from a resource standpoint although from the author of this post indicates like that's the case. I'm still sticking with Google Drive since I only restart my machine about once a month, so this is not too much of a problem for me. In any case, I hope that these issues would get addressed in a future update to the client.
