Cost of using GKE CSI Filestore

[rubans]

I wanted to create a PV using ReadWriteMany and understand for GKE, the simplest solution out of the box seems to using CSI FileStore (https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/filestore-csi-driver)

I understand normally Cloud Filestore is quiet expensive as the min billing is based on 1TB and I only need 5GB. Is that still same GKE CSI Filestore or does it bill based on GB?

Wasn't clear based on existing documentation so pls let me know?

The billing rates for FireStore CSI Driver are the same as the rates for Cloud FileStore.  You can use the following link [1] to see the rates charged per gigabyte or use the calculator to make a better estimate depending on your needs.
