BetterCloud for G Suite's Quota Report tells you how much of their storage quota each user on your domain is utilizing. While Google tends to refer to this as a user's "Drive Storage", a user's storage quota is actually dedicated to both Drive and Gmail storage, and a majority or minority percentage of a user's quota can be taken up by either app.
You can reach the Quota Reports page by navigating from the top menu to Reports > Quotas.
