title: Comparison of uploading files to GCS using Google Drive vs gsutil
body: <p>I have been comparing how to upload files to a cloud storage, one is in-browser (or emulating a browser) and the other is command-line via <code>gsutil</code> to a Google Cloud Storage bucket.</p>
  
  <p>Does Google Drive use gsutil in the backend, or or the uploader a totally customized and proprietary piece of software? Is there a way to achieve upload speeds to a Google Cloud Storage bucket similar to the upload speeds I'm able to achieve via Drive? If not, what would you suggest for how to get upload speeds equivalent to that in Google Drive, to upload files to a GCS bucket?</p>
