If you don't "oversubscribe" your disk space as a matter of policy, you'll force upgrades earlier than most people would consider them necessary. Most users, I'd expect, will be well under quota most of the time. You'd commit all of your disk space to quota long before the space was actually used. In your scenario, you'd be required to expand the disk array whenever it was committed to quota, even if actual use was very low. Every site that I know of which uses quotas handles disk upgrades when utilization requires it, not when quota subscription does.
