Oh good grief, stay away from Google drive -it'll only make things worse.

I had similar issues with the sheer amount of files in some directories (moi is actually far from the worst, but i was also shocked the first time i saw the count for such an efficient program)

I'm not fond of bashing software or services but Google Drive just cannot compete with Dropbox.
As I (still happily) use Google for every other service i thought it would make sense to consolidate it and move my large pro Dropbox account over. Big mistake.
That was 4 months ago, and as of yesterday I gave up. I miss the stability of Dropbox

Moi is superbly portable on Dropbox - the object library functionality of CustomUI also means assetts are "just there" when needed (saved some embarrassment recently at a client meeting and I'd forgotten two essential products.)

So stick with it.. the file count is only a problem on initial indexing and sync.. :)
