Amazon S3/Glacier don't just provide some random cloud storage, but availability from specific locations, guaranteed bandwidth/rate, detailed logging, API, etc.

Amazon S3/Glacier don't just provide some random cloud storage, but availability from specific locations, guaranteed bandwidth/rate, detailed logging, API, etc. While Google Drive might be an interesting place to just store "some stuff", it's not really comparable for any larger scaled application. I'm not sure what bandwidth Google Drive provides, but looking at Dropbox, I'd never want to serve any customer with that "crappy" < 1 MiB/s speed. It's okay for all the small changes Dropbox is designed for, but for serving as public storage space, it's not really acceptable.
