Everything here https://firebase.google.com/pricing/ that says "/GB" in Blaze plan, if I have less than GB will the price be calculated lower (like Amazon Web Service's) or billed as full GB?

Want to move from AWS but my app has rather small database/storage but requires large amount of access that it exceeded Spark plan. It would be a shame if Firebase bill me full $5 for realtime database that have barely anything. (In that case stick with AWS might be better)

I know this should go to their support but unfortunately this page https://firebase.google.com/support/ told me to come here, and their direct support is capped at 5 times per year..

Prorated. Calculated lower.

Storage charges are prorated on a per-object basis
